BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Globus and its wholly-owned subsidiaries. All intercompany balances and transactions are eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates, in part, on historical experience that management believes to be reasonable under the circumstances. Actual results could differ from those estimates. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the condensed consolidated financial statements in the period they are determined to be necessary. Significant areas that require management’s estimates include intangible assets, contingent payment liabilities, allowance for doubtful accounts, stock-based compensation, write-down for excess and obsolete inventory, useful lives of assets, the outcome of litigation, recoverability of intangible assets and income taxes. We are subject to risks and uncertainties due to changes in the healthcare environment, regulatory oversight, competition, and legislation that may cause actual results to differ from estimated results.
Marketable Securities	Marketable Securities Our marketable securities include municipal bonds, corporate debt securities, commercial paper, securities of U.S. government-sponsored agencies and asset-backed securities, and are classified as available-for-sale as of June 30, 2017. Available-for-sale securities are recorded at fair value in both short-term and long-term marketable securities on our condensed consolidated balance sheets. The change in fair value for available-for-sale securities is recorded, net of taxes, as a component of accumulated other comprehensive loss on our condensed consolidated balance sheets. Premiums and discounts are recognized over the life of the related security as an adjustment to yield using the straight-line method. Realized gains or losses from the sale of our marketable securities are determined on a specific identification basis. Realized gains and losses, along with interest income and the amortization/accretion of premiums/discounts are included as a component of other income, net, on our condensed consolidated statements of income. Interest receivable is recorded as a component of prepaid expenses and other current assets on our condensed consolidated balance sheets. We maintain a portfolio of various holdings, types and maturities, though most of the securities in our portfolio could be liquidated at minimal cost at any time. We invest in securities that meet or exceed standards as defined in our investment policy. Our policy also limits the amount of credit exposure to any one issue, issuer or type of security. We review our securities for other-than-temporary impairment at each reporting period. If an unrealized loss for any security is considered to be other-than-temporary, the loss will be recognized in our condensed consolidated statement of income in the period the determination is made.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first-in, first-out basis. The majority of our inventories are finished goods and we utilize both in-house manufacturing and third-party suppliers to source our products. We periodically evaluate the carrying value of our inventories in relation to our estimated forecast of product demand, which takes into consideration the estimated life cycle of product releases. When quantities on hand exceed estimated sales forecasts, we record a write-down for such excess inventories.
Revenue Recognition	Revenue Recognition Revenue is recognized when persuasive evidence of an arrangement exists, product delivery has occurred, pricing is fixed or determinable, and collection is reasonably assured. A significant portion of our revenue is generated from consigned inventory maintained at hospitals or with sales representatives. For these products, revenue is recognized at the time the product is used or implanted. For all other transactions, we recognize revenue when title to the goods and risk of loss transfer to customers, provided there are no remaining performance obligations that will affect the customer’s final acceptance of the sale. Our policy is to classify shipping and handling costs billed to customers as sales and the related expenses as cost of goods sold.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09 amends the guidance in former Topic 605, Revenue Recognition, and most other existing revenue guidances in US GAAP. Under the new standard, an entity will recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the payment to which the entity expects to be entitled in exchange for those goods or services and provide additional disclosures. As amended, the effective date for public entities is annual reporting periods beginning after December 15, 2017 and interim periods therein. Early adoption is not permitted prior to the first quarter of 2017. We will adopt ASU 2014-09 effective January 1, 2018 using the modified retrospective method (retrospective application with the cumulative effect of initially applying the guidance recognized at the date of initial application). This update will not have a material impact on our financial position or results of operations. The updated guidance will require additional disclosure regarding our revenue transactions. In July 2015, the FASB released ASU 2015-11, Simplifying the Measurement of Inventory (Topic 330) (“ASU 2015-11”) as part of the FASB’s Simplification Initiative. This update is intended to more closely align the measurement of inventory under GAAP with the measurement of inventory under International Financial Reporting Standards. Within the scope of the update, an entity is required to measure inventory at the lower of cost or net realizable value. Net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonable and predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for all public entities for fiscal years beginning after December 31, 2016, including interim reporting periods within that period, and is required to be applied prospectively, with early adoption permitted. We adopted ASU 2015-11 on January 1, 2017. This update does not have a material impact on our financial position, results of operations, and disclosures. In February 2016, the FASB released ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all leases with terms greater than 12 months, whether operating or financing, while the income statement will reflect lease expense for operating leases and amortization/interest expense for financing leases. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, and requires the use of the modified retrospective method, which will require adjustment to all comparative periods presented in the consolidated financial statements. We are currently evaluating the impact of this update on our financial position, results of operations, and disclosures. In March 2016, the FASB released ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which will simplify the income tax consequences, accounting for forfeitures, and classification on the statements of cash flows. ASU 2016-09 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016, and is required to be applied either prospectively, retrospectively or using a modified retrospective transition method, depending on the area covered in this update. We adopted ASU 2016-09 effective January 1, 2017. ASU 2016-09 requires that all excess tax benefits and tax deficiencies are recognized as income tax expense or benefit in the income statement as discrete items in the reporting period in which they occur. The adoption of this provision is required to be applied using a prospective transition method, therefore prior period net income has not been adjusted. Under the provisions of the new guidance, we elected to account for forfeitures as they occur, and using the required modified retrospective adoption, the impact to retained earnings was immaterial. We elected to apply the presentation requirements for cash flows related to excess tax benefits retrospectively to all periods presented. As a result of this retrospective application, our cash provided by operating activities increased by $0.8 million for the six months ended June 30, 2016, and our cash provided by financing activities decreased by $0.8 million for the six months ended June 30, 2016. In October 2016, the FASB released ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”). ASU 2016-16 removes the current exception in US GAAP prohibiting entities from recognizing current and deferred income tax expenses or benefits related to transfer of assets, other than inventory, within the consolidated entity. The current exception to defer the recognition of any tax impact on the transfer of inventory within the consolidated entity until it is sold to a third party remains unaffected. This update is effective for public entities for annual reporting periods beginning after December 15, 2017. Early adoption is permitted and should be in the first interim period if an entity issues interim financial statements. We are currently evaluating the impact of this new accounting standard on our financial position, results of operations, and disclosures. In November 2016, the FASB released ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires that amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. Transfers between cash and cash equivalents and restricted cash and restricted cash equivalents will no longer be presented in the statement of cash flows. The amendments in this update should be applied using a retrospective transition method to each period presented. This update is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years; early adoption is permitted, including adoption in an interim period. We do not expect the adoption of this update to have any material impact on our financial position, cash flows, or disclosures. In January 2017, the FASB released ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The amendments in this ASU should be applied prospectively and are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early application permitted. No disclosures are required at transition. We are currently evaluating the timing and impact of the new standard on our financial position, results of operations and disclosures. In January 2017, the FASB released ASU 2017-04, Intangibles - Goodwill and Other (Topic 805): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which eliminates the Step 2 calculation for the implied fair value of goodwill to measure a goodwill impairment charge. Under the updated standard, an entity will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. ASU 2017-04 does not change the guidance on completing Step 1 of the goodwill impairment test and still allows an entity to perform the optional qualitative goodwill impairment assessment before determining whether to proceed to Step 1. This update is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted for any impairment test performed on testing dates after January 1, 2017. We are currently evaluating the timing and impact of the new standard on our financial position, results of operations and disclosures. In May 2017, the FASB released ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”), which clarifies the changes to terms or conditions of a share based payment award that requires application of modification accounting under Topic 718. A change to an award should be accounted for as a modification unless the fair value of the modified award is the same as the original award, the vesting conditions do not change, and the classification as an equity or liability instrument does not change. This update is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2017. Early application is permitted and prospective application is required for awards modified on or after the adoption date. This update will not have a material impact on our financial position, results of operations or disclosures.

Disclosure of accounting policy for investments in financial assets, including marketable securities (debt and equity securities with readily determinable fair values), investments accounted for under the equity method and cost method, securities borrowed and loaned, and repurchase and resale agreements. For marketable securities, the disclosure may include the entity's accounting treatment for transfers between investment categories and how the fair values for such securities are determined. Also, for all investments, an entity may describe its policy for assessing, recognizing and measuring impairment of the investment.
