Scaphoid fractures are generally known to be difficult to diagnose and difficult to heal. In some reports, up to 40% of scaphoid fractures were reported to be missed at initial presentation. Clinical examinations and plain radiographs are generally poor at identifying scaphoid fractures immediately after injury. In this study we report a scaphoid fracture that has no difficulty in diagnosis bec...

Avascular necrosis of the scaphoid following a fracture in children is rare and there is no established treatment protocol in the literature. We present two boys with nonunion and avascular necrosis of the scaphoid treated by simple immobilisation. Both cases healed with painless wrists and full movements. Our cases confirm that an ununited scaphoid fracture in children may heal with conservati...

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...

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 palmar dislocation of scaphoid and lunate is uncommon. We have found only 19 reported cases in the literature. We reported a simultaneous, divergent dislocation. The closed reduction followed by percutaneous pinning has given a good result without avascular necrosis of any carpal bone.

Isolated carpal scaphoid dislocations are rare. Because of this, treatment strategies can be conflicting and vague. The current authors present a case of isolated scaphoid dislocation that was treated initially with closed reduction and percutaneous pinning. Failure of this index treatment necessitated open reduction and internal fixation providing an adequate short-term outcome. Current treatm...

BACKGROUND To determine the association between lunate morphology and the scapholunate instability using radiographic images, and investigate the association between lunate morphology and scaphoid fracture location. METHODS Between January 2003 and December 2011, we retrospectively evaluated the plain radiographs and computed tomography (CT) images of 70 patients who underwent surgical interv...

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 ...
