Abstract
Scaphoid non-unions management has four main goals: first is to restore articular surface as the scaphoid is predominantly articular. The second goal is to correct the deformity, the third goal is to keep the ligamentous attachment while the fourth goal is to preserve scaphoid vascularity. Reconstruction of collapsed scaphoid non-unions with humpback deformity using the volar approach usually violates wrist joint capsule and its ligamentous structures as well as its blood supply. This may risk joint stability and may lead to stiffness. Arthroscopic correction of humpback deformity and its fixation has the advantage of achieving an accurate reduction of articular surface and high success rate regarding time to union that allows for early rehabilitation and return to function. Although arthroscopic technique is a minimally invasive surgery, it is a challenging procedure that needs a lot of practice and high experience.
The aim of this work was to evaluate the results of arthroscopic management of scaphoid fracture non-union with humpback deformity.
In this study, 20 patients suffering from non-united scaphoid fractures were treated by arthroscopic debridement, reduction, fixation and bone grafting.
All patients were examined both clinically and radiologically on admission. The age of the patients ranged from 19 to 39 years with an average of 28 years. All patients were males. The right side was affected in 14 (70%), and the left in 6 patients (30%). The dominant hand was affected in 18 patients (90%). Eleven patients (55%) were light workers, 9 (45%) were heavy manual workers. The mean duration of symptoms was 15.45 months.
