Evaluating Outcomes of Arthroscopic-assisted Treatment of Scaphoid Nonunion

Abstract

Background: Scaphoid nonunion is not uncommon and may eventually lead to complications such as deformity, instability, and degenerative changes. Open reconstruction could jeopardize vascular supply and cause capsular contracture. Arthroscopic treatment of scaphoid nonunion is an effort to avoid such complications. Objectives: This study evaluated the mid-term results of arthroscopic assisted treatment of scaphoid nonunion. Methods: Fifteen patients who underwent arthroscopic assisted treatment of scaphoid nonunion were included in the study. Ten patients had scaphoid waist fractures, while in five patients, the fracture was in the proximal pole. The union was evaluated radiographically three months, six months, and one year after surgery. The range of active motion, grip strength, and standard disability questionnaires such as disabilities of the arm, shoulder, and hand (DASH), patient-related wrist evaluation (PRWE), and modified Mayo wrist scales were evaluated one year after surgery. Results: Based on radiographic findings, all patients' fractures were satisfactorily united after three months. Functional scores, motion range, and grip strength improved to an acceptable level. There was no complication, including infection or nerve damage. Conclusions: Arthroscopic treatment of scaphoid nonunion seems to be an effective method with low complications and favorable results.
