The wrist represents a complex anatomic region in the human extremity and a highly functional and intricate structural joint. Most perilunate injuries result from a staged disruption of the ligamentous structures. Forces may be directed through the carpal bones themselves resulting in a fracture. Early anatomic reduction of any carpal malalignment is of the utmost importance. Unfortunately, eve...

The wrist is a region that is very vulnerable to injuries of the extremities. Among these injuries, fractures of the pyramidal bone (or triquetrum) in association with dislocation of the hamate and carpal instability are uncommon. They are generally correlated with high-energy trauma and may be associated with neurovascular deficits, muscle-tendon disorders, skin lesions or injuries to other ca...

The purpose of this study was to review the clinical results of carpal ligaments injuries with scaphoid nonunion. We hypothesized that scaphoid nonunion with carpal ligament injury is associated with clinical result. We retrospectively reviewed 60 cases of -Herbert screw fixation with bone graft for scaphoid nonunions. Scapholunate (SL) and lunotriquetral (LT) ligaments lesions were confirmed b...

Carpal dislocation and fracture dislocation are uncommon and difficult to treat. Early diagnosis and treatment of such injuries are necessary to prevent progressive carpal instability and traumatic arthritis. Perilunate fracture dislocation is a combination of ligamentous and osseous injuries that involve the 'greater arc' of the perilunate. Despite being severe, these injuries often go unrecog...

Injuries to the scapholunate joint [SLJ] are the most frequent cause of carpal instability and account for a considerable degree of wrist dysfunction. It is insufficient to cause abnormal carpal posture or collapse on static radiographs, an isolated injury to the scapholunate interosseous ligament may cause progression to abnormal joint mechanics, cartilage wear, and degenerative changes. Inter...

Perilunate dislocations, lunate dislocations and perilunate fracture dislocations are rare injuries comprising of less than 10% of all wrist injuries. Volar peri-lunate dislocations (VPLDs) account for less than 3% of perilunate dislocations. These severe carpal injuries occur after high-energy trauma to the wrist and falls on the outstretched hand. We present a case of a missed VPLD who develo...

Objective: To describe the results of the endoscopic carpal tunnel release using the MicroAire Carpal Tunnel Release System. Methods: This descriptive study was conducted from June 2007 to May 2009 on 63 patients (68 hands) who underwent endoscopic carpal tunnel release for severe carpal tunnel syndrome in the Royal Jordanian Rehabilitation Center at King Hussein Medical Center. The procedure w...

Since Destot in 1905, the study of intracarpal injuries has interested many authors who were faced with wrist traumatisms [ 1– 7 ] . Therefore, the analysis of the sole traumas is not enough to understand carpal biomechanics. Studies have thus been led in different directions to solve injuries’ mechanism. Imaging studies dealt with the radiography of healthy subjects [ 8– 17 ] , with the in vit...

2 Department of Orthopaedic Surgery, Massachusetts General Hospital, Boston, MA Perilunate injuries result from high-energy trauma to the carpus. Early diagnosis and treatment is essential to optimizing outcome. Initial management should consist of closed reduction of any carpal malalignment. Subsequent open reduction with percutaneous pinning or internal screw fixation and soft tissue repair i...

From a mechanical point of view, the wrist represents the most complex joint in the body, providing a large range of motion in the flexion-extension (FE) and radial-ulnar-deviation (RUD) planes. Anatomically, the wrist could be divided into two carpal rows. Deeper insight into wrist biomechanics is highly desirable, because the complex wrist structure causes a variety of possible injuries and t...
