Three cases of absence of the carpal scaphoid bone have previously been reported in this country (Hodgson 1943, Hanley and Conlon 1957). All three had similar deformities, namely absence or hypoplasia of the carpal scaphoid bone, associated with retardation in the development of the first metacarpal bone, the styloid process of the radius and thenar muscles. While agreeing with these authors th...

OBJECTIVES To measure the rate of union in patients with pseudoarthosis of the scaphoid, treated with trapezoidal bone grafting as outlined by Fernandez and 1 of 3 methods of internal fixation and to compare unions versus nonunions and potential predictors of union to determine if associations exist. DESIGN A retrospective radiologic study of scaphoid pseudoarthroses. SETTING Division of Or...

BACKGROUND Fractures of the scaphoid are well known to be problematic especially when complicated by avascular necrosis, nonunion and carpal collapse. Fixation techniques have involved nonvascularised bone grafting; however, in the presence of avascular necrosis, generally poor union rates (47%) occur as identified by a meta-analysis performed by Merrell et al. The introduction of pedicled vasc...

Chondromyxoid fibroma is a rare benign cartilage-forming tumor, counting for 0.5% of all primary bone tumors . The development of Chondromyxoid fibroma in the carpal bones is extremely rare. This article describes a rare case report of Chondromyxoid Fibroma in Scaphoid bone of a 15 year male. To our knowledge, this is the first report of Chondromyxoid fibroma in Scaphoid. The rarity of the lesi...

Aims The aim of the Scaphoid Waist Internal Fixation for Fractures Trial (SWIFFT) was to determine optimal treatment adults with a bicortical undisplaced or minimally displaced fracture waist scaphoid, comparing early surgical fixation initial cast immobilization, immediate being offered patients nonunion. Methods A cost-effectiveness analysis conducted assess relative merits these forms treatm...

We have reviewed 22 patients with scaphoid fractures treated by internal fixation with the Herbert screw. Three patients had trans-scaphoid perilunar dislocations, one had an oblique displaced fracture of the waist of the scaphoid and 18 had fractures with delayed or non-union. Corticocancellous bone grafts were added in nine of the cases of non-union. Results were excellent or good in 80% of c...

BACKGROUND The scaphoid fractures account for 50%-80% of all carpal bone fractures in young individuals. Non-union of the fracture occurs in approximately 5%-10% of undisplaced scaphoid fractures. Current management varies significantly among different places and surgeons. OBJECTIVES The purpose of this review is to investigate the evidence of the effectiveness and safety of various treatment...

BACKGROUND Poor reduction or neglect of an unstable carpal scaphoid fracture may lead to scaphoid nonunion or avascular necrosis. When pre-operative suggestion of avascular necrosis of the proximal pole is confirmed by intra-operative evaluation, conventional bone graft is not enough and a vascularized bone graft is strongly recommended. METHODS Five patients with nonunion of scaphoid fractur...

A displaced fracture of the scaphoid is one in which the fragments have moved from their anatomical position or there is movement between them when stressed by physiological loads. Displacement is seen in about 20% of fractures of the waist of the scaphoid, as shown by translation, a gap, angulation or rotation. A CT scan in the true longitudinal axis of the scaphoid demonstrates the shape of t...
