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...

We have investigated whether assessment of blood flow to the proximal scaphoid can be used to predict nonunion in acute fractures of the scaphoid. We studied 32 fractures of the scaphoid one to two weeks after injury, by dynamic fat-suppressed T1-weighted gradient-echo MRI after the intravenous administration of gadopentetate dimeglumine (0.1 mmol/kg body-weight). Steepest slope values (SSV) an...

Scaphoid fractures are the most common carpal fractures; their overall incidence is however low. Missing a scaphoid fracture may lead to a non-union with a possible disastrous outcome for the patient; for this reason, treatment of a suspected scaphoid fracture, even without a proven fracture on the first radiograph, has been conservative with plaster treatment. There are many clinical tests dev...

BACKGROUND Surgically, it is difficult to achieve union of a scaphoid nonunion that is associated with osteonecrosis of the proximal pole, and those with carpal collapse are especially difficult to treat. A variety of vascularized bone grafts can be used. The purpose of this study was to compare the effectiveness of two types of vascularized bone graft -- a distal radial pedicle graft and a fre...

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...

The scaphoid is the most common of the carpal bones to fracture; upper limb fractures are associated in 5-10% of cases, and around 2% of the concomitant fractures are of the distal radius. One case of bilateral carpal scaphoid fractures associated with bilateral distal radius fractures is presented. Radiographs showed displaced Salter-Harris Type II radius fracture and nondisplaced transverse m...

BACKGROUND Scaphoid fractures are common, but can easily be overlooked clinically. The purpose of this study was to determine the incidence of this injury and the treatment outcome for patients with scaphoid fractures in our department. MATERIAL AND METHOD All patients with scaphoid fractures who were treated in the Orthopaedic Section of Haugesund Hospital from 1987 up to and including 2011 ...

PURPOSE To assess the results of a hybrid Russe procedure using a corticocancellous strut, cancellous autologous nonvascularized bone graft, and cannulated headless compression screw to reduce the deformity reliably from a collapsed scaphoid nonunion, provide osteoinductive stimulus, and stabilize the fracture for predictable union. METHODS A hybrid Russe procedure was performed for scaphoid ...

Despite the high incidence of scaphoid fractures, their diagnosis and treatment is often delayed which can lead to complications such as non-union, avascular necrosis, and future arthritis. We present three cases with non-classical mechanisms of injury, leading to a delayed diagnosis in all three cases. Our cases serve to emphasize the importance of a high index of suspicion for the possibility...

BACKGROUND Traditionally, acute undisplaced or minimally-displaced scaphoid fractures are treated by casting in short- or long-arm casts. Although reports have shown that operative treatment is safe, effective and produces satisfactory results, outcomes from current studies comparing these two methods are questionable. The aim of this meta-analysis was to evaluate the effects of operative versu...
