Amendment Description We are filing this Amendment No. 1 on Form 10-Q/A to amend and restate in their entirety the following items of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2017 as originally filed with the Securities and Exchange Commission on August 14, 2017 (the “Original Form 10-Q”): (i) Item 1 of Part I “Condensed Consolidated Financial Statements,” (ii) Item 2 of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and (iii) Item 4 of Part I, “Controls and Procedures,” in Exhibits 31.1, 31.2, 32.1 and 32.2, and our financial statements formatted in Extensible Business Reporting Language (XBRL) in Exhibits 101. No other sections were affected, but for the convenience of the reader, this report on Form 10-Q/A restates in its entirety, as amended, our Original Form 10-Q. This report on Form 10-Q/A is presented as of the filing date of the Original Form 10-Q and does not reflect events occurring after that date, or modify or update disclosures in any way other than as required to reflect the restatement described below. We have determined that our previously reported results for the six months ended June 30, 2017 erroneously recorded accumulated depreciation on surgical instruments. Correcting the error requires a decrease in property and equipment, net, in the amount of $617,627 and a related increase in cost of goods sold. Detection of the error resulted in the restatement of the condensed consolidated balance sheet, condensed consolidated statement of operations, condensed consolidated statement of cash flows and Note 4, property and equipment, net for the six months ended June 30, 2017 included in this Form 10-Q/A. We have made necessary conforming changes in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” resulting from the correction of this error.
