Percutaneous Screw Fixation for Scaphoid Fractures

摘要

Treatment of nondisplaced scaphoid waist fractures has evolved from conventional cast immobilization to percutaneous screw insertion. This study assessed clinical and radiologic outcomes of volar percutaneous screw fixation for 15 type B2 scaphoid fractures (according to the Herbert and Fisher classification). All patients were followed for an average of 33 months (range, 6-50 months). All fractures achieved radiographic union at an average of 57 days (range, 35-70 days), requiring no additional procedures. None of the patients showed radiographic signs of osteoarthritis, osteonecrosis of the scaphoid, or hardware-related complications. For scaphoid waist fractures without collapse, percutaneous screw fixation provided satisfactory results with a high rate of union, early return of function, and minimal complications.
