Distal scaphoid resection arthroplasty for scaphoid nonunion with radioscaphoid arthritis.
The authors compare the functional outcome of 8 patients treated by distal scaphoid resection arthroplasty for scaphoid nonunion with symptomatic wrist arthritis before surgery and after a minimum follow-up of 6 months. There was a significantly better range of radial deviation and grip strength at the time of re-examination. Significantly fewer patients complained of resting pain. By contrast ...
متن کاملScaphoid Nonunion.
The natural history and treatment of scaphoid fractures and subsequent nonunions have occupied a substantial portion of the orthopaedic literature. The authors examine the role of modern diagnostic tools in making an earlier diagnosis of scaphoid nonunion, in more accurately determining the displacement and angulation of the fragments, and in identifying the presence of avascular necrosis. They...
متن کاملAvascular necrosis of the distal pole of the scaphoid
Avascular necrosis (AVN) of the scaphoid predominantly occurs in the proximal pole. Review of the literature revealed only six cases and all are suspect due to the lack of either MRI investigation or investigation of bleeding preoperatively. We report four new cases and one of them appears to be a real distal pole AVN of the scaphoid in the literature.
متن کاملThe relationship between the site of nonunion of the scaphoid and scaphoid nonunion advanced collapse (SNAC).
We studied retrospectively the radiographs of 33 patients with late symptoms after scaphoid nonunion in an attempt to relate the incidence of scaphoid nonunion advanced collapse (SNAC) to the level of the original fracture. We found differing patterns for nonunion at the proximal, middle and distal thirds. The mean intervals between fracture and complaint were 20.9, 6.7 and 12.6 years and obvio...
متن کاملUlnar variance in scaphoid nonunion.
BACKGROUND Negative ulnar variance can be a risk factor in Kienböck's disease, wrist instability, and scaphoid bone fracture. This study focused on the ulnar variance in wrists with scaphoid bone nonunion. METHODS We retrospectively reviewed posteroanterior wrist radiographs of 65 patients who were diagnosed as established scaphoid nonunion and underwent open reduction and bone grafting betwe...
