Organization And Business Disclosure [Abstract]
Organization and Business	1. Organization and Business Nature of operations Tenon Medical, Inc. (the “Company”), was incorporated in the State of Delaware on June 19, 2012 and was headquartered in San Ramon, California until June 2021 when it relocated to Los Gatos, California. The Company is a medical device company that has developed a novel inferior-posterior approach to sacroiliac joint fusion for treatment of the most common types of sacroiliac joint disorders that cause lower back pain. The Company received U.S. Food and Drug Administration (“FDA”) clearance in 2018 for its primary product, The Catamaran TM Basis of consolidation The consolidated financial statements of the Company include the accounts of the Company and its wholly-owned subsidiary, Tenon Technology AG (“TTAG”), a Swiss company. TTAG was a majority-owned subsidiary until October 28, 2021, at which date the Company acquired the remaining non-controlling interest of TTAG (see Note 8). All intercompany balances and transactions have been eliminated in consolidation.

Accounting Policies [Abstract]
Summary of Significant Accounting Principles	2. Summary of Significant Accounting Principles Basis of presentation We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the SEC. As permitted under these rules and regulations, we have condensed or omitted certain financial information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The unaudited condensed consolidated balance sheet as of December 31, 2021 has been derived from our audited consolidated financial statements, which are included in our amended Registration Statement on Form S-1 filed with the SEC on April 20, 2022 (our “amended Registration Statement”). These condensed consolidated financial statements have been prepared on the same basis as our annual consolidated financial statements and, in management’s opinion, reflect all adjustments consisting only of normal recurring adjustments that are necessary for a fair presentation of our financial information. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The financial statements of the subsidiary are prepared for the same reporting period as the parent, using consistent accounting policies in all material respects. The amount of consolidated net loss attributable to the Company and ownership interests in TTAG held by parties other than the Company are both presented on the face of the Consolidated Statements of Operations. Given that TTAG is a wholly-owned subsidiary as of June 30, 2022, this separate presentation has been discontinued for the three and six months then ended. Further, given that the Company purchased the non-controlling interest in TTAG as of October 28, 2021, the amount of consolidated net loss attributable to the Company and the non-controlling interest are both presented on the face of the Consolidated Statements of Operations and Comprehensive Loss. These unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements as of and for the years ended December 31, 2021 and 2020 included in our amended Registration Statement. The Company’s significant accounting policies are disclosed in the audited consolidated financial statements as of and for the years ended December 31, 2021 and 2020 included in our amended Registration Statement. There have been no material changes in the Company’s significant accounting policies during the six months ended June 30, 2022. Going concern uncertainty and liquidity requirements The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. Since inception, the Company has incurred losses and negative cash flows from operations. Management expects to incur additional operating losses and negative cash flows from operations in the foreseeable future as the Company continues its product development programs and starts the commercial launch of The Catamaran System. On April 29, 2022, the Company closed an initial public offering (the “IPO”) of its common stock for proceeds of $13,765, net of issuance costs. Based on the Company’s current level of expenditures, the Company believes that its existing cash and cash equivalents and short-term investments as of June 30, 2022 will provide sufficient funds to enable it to meet its obligations for a period of at least twelve months from the date of the filing of these consolidated financial statements. Use of estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant estimates made by management include, but are not limited to, realization of deferred tax assets, accrued liabilities, obsolescence of inventory, stock-based compensation and the fair value of the Company’s common stock and preferred stock. Income Taxes The Company accounts for income taxes utilizing ASC 740, “Income Taxes”. ASC 740 requires the measurement of deferred tax assets for deductible temporary differences and operating loss carry forwards, and of deferred tax liabilities for taxable temporary differences. Measurement of current and deferred tax liabilities and assets is based on provisions of enacted tax law. The effects of future changes in tax laws or rates are not included in the measurement. The Company recognizes the amount of taxes payable or refundable for the current year and recognizes deferred tax liabilities and assets for the expected future tax consequences of events and transactions that have been recognized in the Company’s financial statements or tax returns. The Company currently has substantial net operating loss carry forwards. The Company has recorded a 100% valuation allowance against net deferred tax assets due to uncertainty of their ultimate realization. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Impact of COVID-19 In March 2020, the World Health Organization declared the coronavirus (“COVID-19”) outbreak to be a pandemic. During the years ended December 31, 2021 and 2020, the Company’s financial results were not significantly affected by the COVID-19 outbreak. The Company has considered all information available as of the date of issuance of these consolidated financial statements and the Company is not aware of any specific events or circumstances that would require an update to its estimates or judgments, or a revision to the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. The extent to which the COVID-19 outbreak affects the Company’s future financial results and operations will depend on future developments which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the outbreak, and current or future domestic and international actions to contain and treat it. Net loss per share Basic net loss per share is based upon the weighted-average number of common shares outstanding. Diluted net loss per share is based on the assumption that all potential common stock equivalents (convertible preferred stock, stock options, and warrants) are converted or exercised. The calculation of diluted net loss per share excludes potential common stock equivalents if the effect is anti-dilutive. The Company’s weighted-average common shares outstanding for basic and diluted are the same because the effect of the potential common stock equivalents is anti-dilutive. The Company had the following dilutive common stock equivalents as of June 30, 2022 and 2021 which were excluded from the calculation because their effect was anti-dilutive. June 30, 2022 June 30, 2021 Outstanding restricted stock units 1,117.530 — Outstanding stock options 727,394 484,787 Outstanding warrants 121,000 25,000 Common shares convertible from notes payable — 2,079,510 Common shares convertible from preferred stock — 245,611 Total 1,965,924 2,834,908 Recent Accounting Pronouncements There have been no accounting pronouncements or changes in accounting pronouncements in the six months ended June 30, 2022 that are significant or potentially significant to the Company.

Leases [Abstract]
Leases	7. Leases In June 2021, the Company entered into a facility lease agreement for its company headquarters in Los Gatos, California. This non-cancelable operating lease expires in June 2026. The Company includes options that are reasonably certain to be exercised as part of the determination of lease terms. The Company may negotiate termination clauses in anticipation of any changes in market conditions, but generally these termination options are not exercised. Residual value guarantees are generally not included within operating leases. In addition to base rent payments, leases may require the Company to pay directly for taxes and other non-lease components, such as insurance, maintenance, and other operating expenses, which may be dependent on usage or vary month-to-month. Non-lease components were considered and determined not to be material. The Company determined if an arrangement is a lease at inception of the contract in accordance with guidance detailed in the new standard and performed the lease classification test as of the lease commencement date. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease’s commencement date based on the present value of lease payments over the lease term. When a lease did not provide an implicit rate, the Company used its estimated incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments. Operating lease costs for the facility lease were $73 and $12 for the three months ended June 30, 2022 and 2021, respectively, and were $146 and $12 for the six months ended June 30, 2022 and 2021, respectively. Lease costs are included in general and administrative expenses in the consolidated statements of operations and comprehensive loss.

Equity [Abstract]
Stockholders' Equity	8. Stockholders’ Equity The Amended and Restated Certificate of Incorporation dated February 18, 2014 authorized the issuance of 3,937,550 shares of common stock and 2,099,525 shares of preferred stock, with a par value of $0.001 per share. During April 2021 the Company increased the number of authorized shares to 7,000,000 shares of common stock and 2,460,802 shares of preferred stock, and increased the number of authorized shares of Series A Convertible Preferred Stock (“Series A Preferred Stock”) to 1,798,905. During October 2021 the Company increased the number of authorized shares to 10,487,904 shares of common stock and 3,297,061 shares of preferred stock. During February 2022, the Company increased the number of authorized shares to 130,000,000 shares of common stock and 20,000,000 shares of preferred stock. Reverse Stock Split On April 6, 2022, the Company effected a 1:2 reverse stock split (the “Reverse Stock Split”) by filing an amendment to the Company’s Amended and Restated Certificate Incorporation, as amended, with the Delaware Secretary of State. The Reverse Stock Split combined every two shares of our common stock issued and outstanding immediately prior to effecting the Reverse Stock Split into one share of common stock. Similarly, shares of Series A and Series B Preferred Stock became convertible into common stock at a conversion rate of one-to-0.5, subject to adjustments for stock dividends, splits, combinations, and similar events. No fractional shares were issued in connection with the Reverse Stock Split. All historical and per share amounts reflected throughout this document have been adjusted to reflect the Reverse Stock Split. The authorized number of shares and the par value per share of the Company’s common stock were not affected by the Reverse Stock Split. Initial Public Offering On April 26, 2022, the Company’s Registration Statement relating to the IPO was declared effective by the SEC. The IPO consisted of 3,200,000 shares of common stock, par value $0.001 per share at a public offering price of $5.00 per share. Pursuant to the Underwriting Agreement dated April 26, 2022, between the Company, The Benchmark Company, LLC (“Benchmark”) and Valuable Capital Limited (together with Benchmark, the “Underwriters”), the Company granted the Underwriters warrants to purchase a total of 96,000 shares of the Company’s common stock at an exercise price of $5.00 per share. The warrants expire on the fifth anniversary of the commencement of sales under the IPO. On April 27, 2022, the shares of the Company’s common stock began trading on the Nasdaq Capital Market LLC under the symbol “TNON.” 11 On April 29, 2022, the IPO closed, and the Company received approximately $13.8 million in net proceeds from the IPO after deducting the underwriting discount and commission and other estimated IPO expenses payable by the Company. As a result of the completion of the IPO and as required under the terms of the convertible notes payable described in Note 6, the Company converted the entirety of the related outstanding principal and accrued interest to 3,955,415 shares of the Company’s common stock at the conversion price detailed in Note 6 and issued the common stock to the noteholders, fully satisfying the Company’s obligations. On April 29, 2022, as result of the completion of the IPO, the Company converted all shares of Series A and Series B Preferred Stock to 2,693,342 shares of the Company’s common stock at the conversion rate detailed below and issued the common stock to the preferred stockholders, fully satisfying the Company’s obligations. This includes 1,172,346 shares issued to TTAG’s minority shareholder in accordance with the anti-dilution protection provisions of the Exchange Agreement. Concurrent with the completion of the IPO and in accordance with the Amended and Restated Exclusive Sales Representative Agreement executed in May 2021, the counterparty to the agreement received anti-dilution protections to maintain ownership of 3.0% of the fully diluted equity of the Company through the date of an initial public offering and was issued 312,351 shares of the Company’s common stock to the Representative, fully satisfying the Company’s obligations. Also, as a result of the completion of the IPO, the Company issued 85,739 shares of its common stock to a consultant. The value of these shares issued at the IPO price of $5.00 per share was charged to operating expenses in the Company’s financial statements. Preferred Stock On October 28, 2021, the Company entered into an Agreement (the “Exchange Agreement”) with TTAG’s minority shareholder. Pursuant to the Exchange Agreement, TTAG’s minority shareholder agreed to exchange 574,033 shares of Series A Convertible Preferred Stock issued by TTAG, representing its entire ownership interest in TTAG, for the Company’s Series A Preferred Stock, representing a 24% ownership interest in the Company’s fully-diluted capital, which includes the pro forma conversion of all outstanding convertible preferred stock and promissory notes, options, and warrants. Pursuant to the terms of the Exchange Agreement, the Company issued TTAG’s minority shareholder 2,550,763 shares of Series A Preferred Stock. These shares were subject to anti-dilution protection to maintain TTAG’s minority shareholder’s 24% ownership interest in the Company, excluding any shares issued by the Company in an IPO or a qualified offering of at least $5,000 at a per share price of at least $3.3737. Upon conversion of the Company’s convertible notes payable as described in Note 6, the Company issued 1,172,346 shares of its common stock to TTAG’s minority shareholder. In accordance with ASC 810-10-45-23, the Company did not recognize any gain or loss in the consolidated statements of operations and comprehensive loss in conjunction with the Exchange Agreement. The carrying value of the non-controlling interest in TTAG was reduced to zero, and the value of the Company’s investment in TTAG increased accordingly. The shares of Series A Preferred Stock issued were recorded at fair value. The difference between the increase in the Company’s investment and the fair value of the Series A Preferred Stock issued was recorded as a decrease in Additional Paid in Capital (“APIC”). The resulting negative APIC was then reclassified to accumulated deficit. In a series of closings from 2012 through 2015, the Company issued an aggregate of 491,222 shares of Series B Convertible Preferred Stock (“Series B Preferred Stock”) at $2.795 per share for proceeds of $1,272, net of stock issuance costs. The Company classified the convertible preferred stock outside of total stockholders’ deficit because, in the event of certain deemed liquidation events that are not solely within the control of the Company, the shares would become redeemable at the option of the holders. The Company did not adjust the carrying values of the convertible preferred stock to the deemed liquidation values of such shares since a liquidation event was not probable of occurring. Conversion At the option of the holder, shares of Series A and Series B Preferred Stock were convertible into common stock at a conversion rate of one-to-0.5, subject to adjustments for stock dividends, splits, combinations, and similar events. Automatic conversion will occur in the event of a firmly underwritten public offering of common stock of the Company at a price of at least $4.00 per share, subject to appropriate adjustments for stock dividends, splits, combinations, and similar events, and with total gross proceeds to the Company of at least $15,000, before deduction of underwriters’ commissions and expenses. As noted above, the Series A and Series B Preferred Stock were converted to common stock at the time of the Company’s IPO. Redemption The shares of the Series A and Series B Preferred Stock were redeemable only upon acquisition or liquidation of the Company. Liquidation preference With respect to any distributions in connection with a liquidation, dissolution or winding up of the Company, or in connection with the sale of voting control of all or substantially all of the assets of the Company, by way of merger, acquisition, consolidation or similar transaction, prior to any distribution to common stockholders, the holders of Series A and Series B Preferred Stock were entitled to receive $1.526 and $4.981 per share, respectively, plus any declared but unpaid dividends, adjusted to reflect any dividends previously paid. If, upon the occurrence of such event, the assets and funds distributed among the holders of Series A and Series B Preferred Stock shall be insufficient to permit the payment to such holders of the full liquidation preference amounts, the entire assets and funds of the Company legally available shall be distributed ratably among the preferred stockholders in proportion to the preferential amount to which each holder is entitled. After payment of the liquidation preferences, the holders of common stock are entitled to receive the remaining assets of the Company available for distribution to its stockholders pro rata based on the number of shares of common stock held by each holder. Voting rights The holders of vested shares of common stock shall be entitled to vote on any matter submitted to a vote of the stockholders and each such holder shall be entitled to one vote per share of common stock held. The holders of Series A and Series B Preferred Stock were entitled to vote together with the common stock as a single class on any matter submitted to a vote of the stockholders. Holders of Series A and Series B Preferred Stock were entitled to the number of votes equal to the number of common stock issuable upon conversion of their respective Series A and Series B Preferred Stock at the time such shares are voted. The holders of a majority of the preferred stock had additional voting rights as specified in the Company’s Amended and Restated Certificate of Incorporation, as amended. Equity awards In 2012, the Board of Directors of the Company (the “Board”) approved the Tenon Medical, Inc. 2012 Equity Incentive Plan (the “2012 Plan”). The 2012 Plan provides for the issuance of common stock options, appreciation rights, and other awards to employees, directors, and consultants. Options issued under the 2012 Plan generally vest over a period of two On January 10, 2022 and February 2, 2022, the Board and stockholders, respectively, of the Company approved the Tenon Medical, Inc. 2022 Equity Incentive Plan (the “2022 Plan”), which was effective on April 25, 2022. The number of shares of common stock that may be subject to awards and sold under the 2022 Plan is equal to 1,600,000. Automatic annual increases in number of shares available for issuance under the 2022 Plan is equal to the least of (a) 1,100,000 shares, (b) 4% of the total number of shares of all classes of common stock outstanding on the last day of the immediately preceding fiscal year, or (c) such number determined by the 2022 Plan administrator no later than the last day of the immediately preceding fiscal year. Annual increases will continue until the tenth anniversary of the earlier of the Board or stockholder approval of the 2022 Plan, which is January 10, 2032. Upon the effective date of the 2022 Plan, the Board terminated the 2012 Plan such that no new equity awards will be issued by the 2012 Plan. The Company adopted the fair value recognition provisions in accordance with authoritative guidance related to equity-based payments. Compensation expense in 2022 and 2021 includes the portion of awards vested in the periods for all equity-based awards granted, based on the grant date fair value estimated using a Black-Scholes option valuation model, consistent with authoritative guidance. A summary of the Company’s share option and restricted stock unit activity under its plans is as follows: Number of Weighted Number of Outstanding Weighted- Outstanding at December 31, 2021 727,394 $ 5.32 — $ — Granted — $ — 1,117,530 $ 8.86 Forfeited — $ — — $ — Outstanding at June 30, 2022 727,394 $ 5.32 1,117,530 $ 8.86 The following table sets forth stock-based compensation expense recognized for the three and six months ended June 30, 2022 and 2021: Three months ended June 30, Six months ended June 30, 2022 2021 2022 2021 Research and development $ 178 $ 13 $ 207 $ 13 Sales and marketing 12 4 24 8 General, and administrative 362 44 490 44 Total stock-based compensation expense $ 552 $ 61 $ 721 $ 65 At June 30, 2022, there were 482,470 shares available for issuance under the 2022 Plan. Warrants During 2020, the Company issued warrants to purchase 25,000 shares of common stock to a consultant. The warrants, which are equity-classified, are immediately exercisable at an exercise price of $5.20 per share. The fair value of the warrants on the grant date was $2.30 per warrant, which was calculated based on the following weighted-average assumptions, using a Black-Scholes option valuation model: expected term of 5.00 years; expected volatility of 51.88%; dividend yield of 0%, and risk-free interest rate of 0.30%. The Company recorded deferred offering costs of approximately $58 associated with these warrants during 2020. In April 2022, as noted above, the Company granted the Underwriters warrants to purchase a total of 96,000 shares of the Company’s common stock. The warrants are immediately exercisable at an exercise price of $5.00 per share and expire on the fifth anniversary of the commencement of sales under the IPO. The fair value of the warrants on the grant date was $2.75 per warrant, which was calculated based on the following weighted-average assumptions, using a Black-Scholes option valuation model: expected term of 5.00 years; expected volatility of 62.55%; dividend yield of 0%, and risk-free interest rate of 2.92%. The Company recorded the fair value of these warrants of approximately $264 as an issuance cost to additional paid-in capital in 2022. As the IPO issuance costs were also recorded to additional paid-in capital, the net impact was $0.

On March 1, 2022, Mr. Mentak filed a more detailed Statement of Claims, which the Company responded to on March 16, 2022.

Given that TTAG is a wholly-owned subsidiary as of June 30, 2022, this separate presentation has been discontinued for the three and six months then ended. Further, given that the Company purchased the non-controlling interest in TTAG as of October 28, 2021, the amount of consolidated net loss attributable to the Company and the non-controlling interest are both presented on the face of the Consolidated Statements of Operations and Comprehensive Loss. These unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements as of and for the years ended December 31, 2021 and 2020 included in our amended Registration Statement. The Company’s significant accounting policies are disclosed in the audited consolidated financial statements as of and for the years ended December 31, 2021 and 2020 included in our amended Registration Statement. There have been no material changes in the Company’s significant accounting policies during the six months ended June 30, 2022.
Going concern uncertainty and liquidity requirements	Going concern uncertainty and liquidity requirements The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. Since inception, the Company has incurred losses and negative cash flows from operations. Management expects to incur additional operating losses and negative cash flows from operations in the foreseeable future as the Company continues its product development programs and starts the commercial launch of The Catamaran System. On April 29, 2022, the Company closed an initial public offering (the “IPO”) of its common stock for proceeds of $13,765, net of issuance costs. Based on the Company’s current level of expenditures, the Company believes that its existing cash and cash equivalents and short-term investments as of June 30, 2022 will provide sufficient funds to enable it to meet its obligations for a period of at least twelve months from the date of the filing of these consolidated financial statements.
Use of estimates	Use of estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant estimates made by management include, but are not limited to, realization of deferred tax assets, accrued liabilities, obsolescence of inventory, stock-based compensation and the fair value of the Company’s common stock and preferred stock.
Income Taxes	Income Taxes The Company accounts for income taxes utilizing ASC 740, “Income Taxes”. ASC 740 requires the measurement of deferred tax assets for deductible temporary differences and operating loss carry forwards, and of deferred tax liabilities for taxable temporary differences. Measurement of current and deferred tax liabilities and assets is based on provisions of enacted tax law. The effects of future changes in tax laws or rates are not included in the measurement. The Company recognizes the amount of taxes payable or refundable for the current year and recognizes deferred tax liabilities and assets for the expected future tax consequences of events and transactions that have been recognized in the Company’s financial statements or tax returns. The Company currently has substantial net operating loss carry forwards. The Company has recorded a 100% valuation allowance against net deferred tax assets due to uncertainty of their ultimate realization. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.
Impact of COVID-19	Impact of COVID-19 In March 2020, the World Health Organization declared the coronavirus (“COVID-19”) outbreak to be a pandemic. During the years ended December 31, 2021 and 2020, the Company’s financial results were not significantly affected by the COVID-19 outbreak. The Company has considered all information available as of the date of issuance of these consolidated financial statements and the Company is not aware of any specific events or circumstances that would require an update to its estimates or judgments, or a revision to the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information becomes available. The extent to which the COVID-19 outbreak affects the Company’s future financial results and operations will depend on future developments which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the outbreak, and current or future domestic and international actions to contain and treat it.
Net loss per share	Net loss per share Basic net loss per share is based upon the weighted-average number of common shares outstanding. Diluted net loss per share is based on the assumption that all potential common stock equivalents (convertible preferred stock, stock options, and warrants) are converted or exercised. The calculation of diluted net loss per share excludes potential common stock equivalents if the effect is anti-dilutive. The Company’s weighted-average common shares outstanding for basic and diluted are the same because the effect of the potential common stock equivalents is anti-dilutive. The Company had the following dilutive common stock equivalents as of June 30, 2022 and 2021 which were excluded from the calculation because their effect was anti-dilutive. June 30, 2022 June 30, 2021 Outstanding restricted stock units 1,117.530 — Outstanding stock options 727,394 484,787 Outstanding warrants 121,000 25,000 Common shares convertible from notes payable — 2,079,510 Common shares convertible from preferred stock — 245,611 Total 1,965,924 2,834,908
