BACKGROUND The carpal scaphoid is the most commonly fractured carpal bone in young adults after a fall on an outstretched arm that results in acute dorsal flexion of the wrist. However, stress fractures of the scaphoid are relatively rare. To the best of our knowledge, we describe the first case in the literature of carpal scaphoid stress fracture in a tennis player. CASE PRESENTATION An 18-y...

The term carpal instability is commonly used, but what carpal stability actually is has not been defined. Much of the mechanically complex wrist’s versatility is due to the intercalated three bone proximal carpal row. Landsmeer described the collapse tendency associated with intercalated segments. The factors which provide static stability are the oblique alignment of the scaphoid, the obliquel...

OBJECTIVES The aim of this study was to assess the cost effectiveness of multiple competing diagnostic strategies for suspected scaphoid fractures. METHODS With published data, the authors created a decision-tree model simulating the diagnosis of suspected scaphoid fractures. Clinical outcomes, costs, and cost effectiveness of immediate computed tomography (CT), day 3 magnetic resonance imagi...

Background and purpose - The epidemiology and optimal diagnostics of wrist injuries in children are not knotwn. We describe fractures revealed by magnetic resonance imaging (MRI) in a prospective population of children and adolescents with posttraumatic radial-sided wrist tenderness, and compare the diagnostic value of radiographs and computed tomography (CT) with that of MRI. Patients and meth...

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...

We have examined whether the rotatory subluxation of the scaphoid which is seen in patients with advanced Kienböck's disease is associated with scapholunate advanced collapse (SLAC) wrist. We studied 16 patients (11 men, 5 women) who had stage-IV Kienböck's disease with chronic subluxation of the scaphoid. All had received conservative treatment. The mean period of affection with Kienböck's dis...

Treatment of nondisplaced scaphoid waist fractures has evolved from conventional cast immobilization to percutaneous screw insertion. This study assessed clinical and radiologic outcomes of volar percutaneous screw fixation for 15 type B2 scaphoid fractures (according to the Herbert and Fisher classification). All patients were followed for an average of 33 months (range, 6-50 months). All frac...

Analysis of radiographs of 52 wrists showed that, from ulnar to radial deviation, the amount of scaphoid shortening and ulnar translation of the scaphoid varies in a normal distribution. There is a significant correlation between the two measurements, such that the more the scaphoid shortens the less it translates and vice versa. Females subjects were more likely to have greater scaphoid shorte...

Nondisplaced fractures of the scaphoid heal with cast immobilization in most cases, but operative treatment is being offered with greater frequency to active patients as an approach to reduce the period of cast immobilization. Computed tomography is more useful for evaluating displacement than standard radiography. Displaced fractures are at greater risk for nonunion and malunion-both of which ...
