We report about a dorsal dislocation of the lunate accompanied by a trapezoid fracture in a 41-year old male patient after a motorcycle accident. The lunate dislocation with no dorsal or volar intercalated segment instability (DISI, VISI) was diagnosed by x-ray whereas the trapezoid fracture was only diagnosable by computed tomography. A closed reduction and internal fixation of the lunate by t...

Lunate dislocations are well described in the volar direction as part of the perilunate dislocation, sometimes together with fractures of the other carpal bones or distal radius, as described by the anatomical studies of Mayfield [1]. It is a result of disruption of the complex inter-carpal and radiocarpal ligaments that hold the well conforming carpus in their normal position. Given the streng...

Scapho-trapezio-trapezoid arthrodesis was originally performed for the treatment of scapho-lunate instability. However, only a few publications have described this technique for treatment of osteoarthritis of the scapho-trapezio-trapezoid (STT) joint. The purpose of this paper is to analyze the results of triscaphoid arthrodesis for STT osteoarthritis with a long-term follow-up. Thirteen cases ...

BACKGROUND The application of radiofrequency energy (RFE) has become widespread for surgical performed chondroplasty especially due to the anticipated sealing effect, however the safety of this procedure in the wrist remains unclear. The purpose of this study was to investigate the subchondral temperature during radiofrequency energy (RFE) application simulating chondroplasty in an arthroscopic...

The movements of the carpal bones during the scaphoid shift test were evaluated radiographically in 60 wrists. The clinical results were graded according to the degree of subluxation of the scaphoid and pain on the dorsum of the wrist. Lateral radiographs at rest and under stress were taken and the relative movements of the scaphoid with respect to the radius and lunate, and the rotation of the...

Lunate fractures are rare and usually occur together with other fractures, dislocations, or ligament disruptions. We want to report an acute fresh isolated lunate fracture without additional ligamentous injury fixated early surgical intervention. A 23-year-old right-hand-dominated male patient was admitted our hospital after falling from 1.5-meter ladder over right hand’s palmar face. Standard ...

background:to determine the prevalence of incidental kienböck disease.   methods: a retrospective analysis of 150,912 radiological reports or images obtained over a five year period was performed of 76,174 patients who underwent a radiograph or computed tomography scan which included the wrist, in edinburgh and lothian, uk. results: there were 5 cases of incidental kienböck disease and 13 cases...
