If neglected or misdiagnosed, non-union of a scaphoid fracture will almost inevitably progress to radiographic and symptomatic osteoarthritis of the wrist with subsequent morbidity and lifelong disability, especially in young males in which the fracture is more common. Fractures of the scaphoid bone are the most common fractures of the carpus and second in occurrence among fractures of the wris...

OBJECTIVE Ulnar variance may be a risk factor of developing scaphoid non-union. METHODS A review was made of the posteroanterior wrist radiographs of 95 patients who were diagnosed of scaphoid fracture. All fractures with displacement less than 1mm treated conservatively were included. The ulnar variance was measured in all patients. RESULTS Ulnar variance was measured in standard posteroan...

A fractured scaphoid is a common disabling injury that is frequently complicated by non-union. The treatment of non-union remains challenging because of the scaphoid's small size and delicate blood supply. Large animal models are the most reliable method to evaluate the efficacy of new treatment modalities before their translation into clinical practice. The goal of this study was to model a hu...

The scaphoid is the most commonly fractured bone in the carpus. Although greater than 90% of scaphoid fractures unite with cast immobilization, failure to heal remains a clinical reality, particularly when the fracture is displaced or associated with intracarpal instability [1–3]. Dabezies [4] reported a 55% incidence of nonunion and a 50% rate of proximal pole avascular necrosis (AVN) in scaph...

Background Scaphoid fractures are common carpal fractures that are often misdiagnosed as wrist sprains and may go on to nonunion. The location of the fracture site may influence the stability of scaphoid nonunions. Purpose To determine whether the stability of a scaphoid nonunion depends upon the fracture's location, we tested the hypothesis that a simulated fracture distal to the apex of the s...

Functional limitations and pain are end results of scaphoid nonunion with progressive carpal collapse and radiocarpal arthritis. The aim of this study was to assess the functional outcome of four-corner arthrodesis with scaphoidectomy for the treatment of grade IV scaphoid nonunion with Scaphoid Nonunion Advanced Collapse (SNAC) stages II and III. Ten patients with symptomatic grade IV non unio...

The nutrient vascular foramina of scaphoid bone were observed and clinical interpretations were discussed. The 220 dry scaphoid bones of adult age group were studied. The vascular foramina distal to mid of waist were 1 to 2 in 17.72 % specimen and rest of 82.28% bones had more then 2 foramina. There was no scaphoid without vascular foramina distal to mid of waist of scaphoid. But the proximal p...

The aim of this review was to present currently available evidence on the management of acute scaphoid fractures. Acute scaphoid fractures are usually diagnosed by a combination of history, physical examination, and radiography. However, in many patients scaphoid fractures are still missed. Thus, the general trend is to over-treat patients with a suspicion of scaphoid fracture. Many aspects of ...
