BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014205189 DESCRIPTION Kienböck’s disease (KD) is characterised by avascular necrosis of the lunate bone and is of unknown aetiology. KD is thought to result from a combination of vascular, anatomic and traumatic insults resulting in interruption of the blood supply to the lunate and ...

Fractures of the lunate are rare injuries that usually result from high-energy trauma and are typically associated with other carpal and ligamentous injuries. The incidence of lunate fractures has been cited as 0.5% to 6.5% of all carpal fractures. These fractures are not frequently reported in the literature, and no consensus exists on the treatment of these injuries in the acute and chronic s...

A 30-year old male right handed professional tennis player complained about reduced athletic performance, chronic pain and restricted extension of his right wrist. Lateral radiograph of the right wrist demonstrated an osteophyte projecting from the dorsal lip of the lunate bone. The presence of an osteophyte on the lateral radiograph of the lunate along with the history, clinical examination, i...

The radiographic files of 70 patients with Kienbock's disease were analyzed. Ulnar variance, carpal height and Kienbick stage were determined. A significant difference in ulnar variance was seen between early and late stages of the disease. In later stages there is a marked negative ulnar variance, not caused by bone apposition on the radius. We hypothesize that negative ulnar variance encourag...

A few numbers of patients admitted to the emergency department due to the lunate dislocation can cause a direct injury to the wrist ligament, which mainly occurs after wrist trauma, and often diagnosis is far from the mind. A 32 years old man due to severe pain and tenderness of the wrist started the previous day during swimming, referred to Emergency Department of Imam Reza Hospital of Mashhad...

A young 22-year-old male presented with complaints of pain, tingling, and numbness over his right wrist for 1 year had a history falls on outstretched hand. Radiological evaluations such as X-rays were done, which showed break in the proximal carpal arc. An MRI affected was done. findings are suggestive avascular necrosis lunate along dislocation marrow edema/contusion lunate. Complete disrupti...

background: abnormal angulation of the lunate can be an indication of intercarpal pathology. on magnetic resonance images (mris) the lunate often looks dorsally angulated, even in healthy wrists. the tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. the primary aim of this study was to deter...

Intraosseous ganglion cysts of the carpal bones located in the lunate are one of the rarely seen pathologic conditions. Here we present a case of the penetrating type of intraosseous ganglion cyst located in the lunate as an uncommon cause of wrist pain. The patient was successfully treated by surgical intervention. Intraosseous ganglion cyst should be considered in the differential diagnosis o...

The pathomechanics, ligamentous damage, and degree of carpal instability in perilunate and lunate dislocations were analyzed by experimentally loading 32 cadaver wrists to failure. Thirteen perilunate and two lunate dislocations were produced. The mechanism of injury was extension, ulnar deviation, and intercarpal supination. These dislocations occurred in a sequential fashion due to progressiv...
