Fusion between the os centrale and the scaphoid has played a central role in many functional and phylogenetic interpretations of hominoid evolution. In particular, scaphoid-centrale fusion shared among African apes and humans has been interpreted as an adaptation in knuckle-walkers, an exaptation in hominins, and has been offered as evidence for a knuckle-walking origin of bipedalism. However, ...

The authors compare the functional outcome of 8 patients treated by distal scaphoid resection arthroplasty for scaphoid nonunion with symptomatic wrist arthritis before surgery and after a minimum follow-up of 6 months. There was a significantly better range of radial deviation and grip strength at the time of re-examination. Significantly fewer patients complained of resting pain. By contrast ...

Introduction: Internal fixation used as treatment for scaphoid fractures has increased with advances in surgical techniques [1]. Proximal pole scaphoid fractures present a clinical challenge due to their lower success rate when cast immobilization and internal fixation are utilized [2]. Screws maximizing length have been shown to impact wrist motion for fixed scaphoid waist fractures [3]. Addit...

UNLABELLED Trans-scaphoid perilunate fracture-dislocation is the most common variety of fracture-dislocations of the wrist. Because of the carpal scaphoid fracture association, post-reduction stability is poor, often requiring surgery. Of the several surgical techniques used over time, percutaneous screw fixation for scaphoid fracture is currently preferred. MATERIAL AND METHODS Six cases of ...

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 Our aim is to study the accuracy of emergency medicine (EM) physician-performed, bedside ultrasonography (BUS) in patients with clinical suspicion of scaphoid fracture and normal radiographs. METHODS From January to December 2011, an EM physician used BUS to prospectively evaluate patients presenting to the emergency department (ED) with clinical suspicion of scaphoid fracture and ...

BACKGROUND/AIM Management of scaphoid trauma includes imaging with repeated X-rays whose interpretation is difficult and often ambivalent. The aim of the study was to propose a fast magnetic resonance imaging (MRI) protocol permitting exclusion of traumatic lesions of the scaphoid bone in children, which would avoid unnecessary immobilization and irradiation in negative cases. PATIENTS AND ME...

One hundred and eleven patients with signs and symptoms of carpal scaphoid injury, but with no fracture visible on X-ray, underwent bone scintigraphy of the wrists. The first 42 patients were re-X-rayed 10 days after injury: bone scanning had identified all fractures confirmed on this X-ray; there were no false negative bone scans. Sixty-seven patients (60%) did not have increased focal uptake ...

Scaphoid fractures are commonly seen in orthopedic practice. An organized and thoughtful approach to diagnosis and treatment can facilitate good outcomes. Anatomical knowledge of the scaphoid is important both for the treatment and prognosis. The blood supply to scaphoid is from distal to proximal pole. Clinical suspicion is of paramount importance. X ray is most important to confirm the diagno...

PURPOSE Partial wrist arthrodesis is a commonly performed procedure for the treatment of posttraumatic wrist arthritis because of its ability to provide pain relief without sacrificing complete wrist motion. The purpose of this study was to evaluate the redistribution of force after four-corner fusion and scaphoid excision, and to correlate the findings with the reported clinical outcomes. ME...
