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...

We report the case of a 21-year-old man who injured his right hand in a fall from his motorbike, causing a trans-scaphoid perilunate fracture-dislocation associated with vertical fracture of the pyramid (A and B). On day 2, patient underwent a bloody reduction (C) of disorganized carpal bones with osteosynthesis of scaphoid and pyramid (D). Peri-lunate fracture-dislocation is a rare injury cons...

Scaphoid fractures are the most common fractures of the carpal bones, corresponding to 60%. Of these, 10% progress to nonunion; moreover, 3% can present necrosis of the proximal pole. There are various methods of treatment using vascularized and non-vascularized bone grafts. To evaluate and compare the rate of scaphoid consolidation with necrosis of the proximal pole using different surgical te...

We reviewed the records of 431 patients who had open reduction and internal fixation of the scaphoid performed by one surgeon (TJH) over a 13-year period. The Herbert bone screw provided adequate internal fixation without the use of plaster immobilisation, promoting a rapid functional recovery. On average, patients returned to work 4.7 weeks after surgery and wrist function was significantly im...

Materials and methods The reconstructed site was the humerus in 15 cases, the radius, the ulna or the wrist joint in 22 cases, carpal or metacarpal bone in 52. The etiologies consisted of three traumatic bone defects, 13 traumatic nonunions of long bone, two osteonecroses of the humeral head, eight osteomyelitis, nine case after resections of bone tumor, two congenital pseudoarthroses of the ul...

A wide range of hand and wrist injuries occur in today's recreational and elite athletes and account for 3% to 9% of all sports injuries. The onus is on the physician to discriminate between injuries that can be managed with an early return to sport, and those injuries that place the athlete at risk of further injury if they are not managed aggressively from the outset. The physician and the at...

A prospective study was undertaken of fifty-one patients who were randomly assigned to treatment with either a long or a short thumb-spica cast for a non-displaced fracture of the carpal scaphoid. The duration of follow-up was at least until union; the average follow-up was twelve months. Twenty-eight fractures were treated with a long thumb-spica cast and twenty-three, with a short thumb-spica...

Understanding the kinematics of the carpus is essential to the understanding and treatment of wrist pathologies. However, accurate measurement of the kinematics of the carpal bones is difficult because they are small bones undergoing complex movements of small amplitudes. As a result, to date, there is no clear consensus on carpal kinematics. Moreover, most studies only investigate single rotat...

BACKGROUND The purpose of this study was to investigate the frequency and distribution of associated carpal bone fractures (CBFs) in distal radial fractures (DRFs). METHODS Three hundred and thirteen patients who underwent surgical treatment for DRFs between March 2007 and January 2010 were reviewed retrospectively. In this study, 223 patients who had preoperative computed tomography (CT) wer...

Perilunate Dislocation Anterior-posterior (AP) view (Figure 1) demonstrates the distal and proximal carpal rows overlapping, as well as a complete radial styloid fracture. Lateral view (Figures 2 and 3) demonstrates dorsal dislocation of the capitate, whereas the lunate remains articulated with the radius. More often seen in young men in their teens to twenties, rather than children or the elde...
