Preoperative 3D CT imaging techniques provide displacement analysis of the distal scaphoid fragment in 3D space, using the matched opposite scaphoid as reference. Its accuracy depends on the presence of anatomical bilateral symmetry, which has not been investigated yet using similar techniques. Our purpose was to investigate symmetry by comparing the relative positions of distal and proximal po...

BACKGROUNDS This paper describes a novel method in treatment of scapholunate dissociation accompanied with rotatory subluxation of the scaphoid. The idea of this method is to create a kind of axial lever that can fully reconstruct anatomical relationship between the scaphoid and the lunate, with no involvement of extrinsic ligaments, and with simultaneous restriction of pathological alignment o...

Trans-scaphoid perilunate fracture dislocations, which account for more than half of total cases injuries, are common in young patients and occur as a result high-energy improper management can impair wrist alignment function. Understanding the related anatomy pathomechanics may help surgeons evaluate diagnose patients. Early operation to reduce fix injuries should be considered achieve optimal...

a case with scaphoid osteochondroma (exostosis) with wrist pain and tender mass. in this case, mass resection was performed with excellent outcome.

Avascular necrosis (AVN) of the scaphoid predominantly occurs in the proximal pole. Review of the literature revealed only six cases and all are suspect due to the lack of either MRI investigation or investigation of bleeding preoperatively. We report four new cases and one of them appears to be a real distal pole AVN of the scaphoid in the literature.

Isolated dislocation of the carpal scaphoid is a rare injury. Such dislocation is extremely rare. In this article the authors report a twenty-eight-year-old man with isolated dislocation of the scaphoid with associating radial styloid fracture. We manage the patient with open reduction and Kirschner wire fixation. One year later there is a good functional and radiographic result.

A rare case of radiocarpal dislocation is presented. The lunate and proximal pole of the scaphoid were displaced in a volar and proximal direction. The injury was missed initially and the patient was subsequently operated on six weeks later. Open reduction and internal fixation of the scaphoid was performed and this was followed by an uneventful postoperative period, with a satisfactory functio...

The authors compare the functional outcome of 26 patients successfully treated by percutaneous osteosynthesis and 24 patients successfully treated by a short-arm thumb cast for the acute scaphoid fracture after a follow-up of at least 12 months. The patients treated by percutaneous osteosynthesis showed a significantly better range of wrist motion at the time of re-examination. Differences in p...

Diagnosing of injuries of the wrist bones is problematic due to a highly complex and variable geometry. knowledge of variations of healthy bone shapes is essential to detect wrist pathologies, developing prosthetics and investigating biomechanical properties of the wrist joint. In previous literature various methods have been proposed to classify different scaphoid and lunate types. These class...
