A 13-year-old girl presented with a 5-month history of right (dominant) wrist pain that resulted from a forced dorsiflexion-type injury. She experienced progressive discomfort in the wrist that subsequently was associated with stiffness and weakness. The pain persisted even though she curtailed her sporting activities, and it became progressive and disabling. She had no history of a fracture or...

Kienböck's disease, defined as avascular necrosis of the lunate, is a relatively rare condition with a poorly understood etiology. Conservative and invasive treatments for Kienböck's disease exist, including wrist immobilization, surgical joint-leveling procedures, vascularized bone grafting, proximal row carpectomy, and total wrist arthrodesis. Staging Kienböck's disease using radiography assu...

Avascular necrosis of the lunate bone (Kienböck disease) is caused by loss of blood supply of the bone. This study aimed to evaluate the efficacy and safety of a novel nickel-titanium (Ni-Ti) memory alloy arthrodesis concentrator in the treatment of this disease.A consecutive 24 patients with stage IIIb aseptic lunate necrosis were treated with scapho-trapezio-trapezoeid (STT) arthrodesis using...

Treatment of stage IIIA and III B avascular necrosis of the lunate bone remains controversial. We present a series of 5 cases in young patients treated with a vascularised bone graft from the second metacarpal, combined with a lateral shortening and closing wedge osteotomy of the radius. Good clinical and radiographic results were obtained and disease progression was halted with the combination...

Treatment of Kienböck's disease has historically been determined by staging, ulnar variance, and presence or absence of arthritic changes. With the advent of newer techniques of vascularized bone grafting, the status of the cartilage shell of the lunate has become another factor that can influence the procedure performed. The purpose of this article is to describe the technique of Kuhlmann vasc...

Chondroma is the most common primary bone tumour of the hand, but carpal chondroma has, as far as we know, been reported only twice previously in the English language literature: in one report by Dahlin (1957), no localisation was mentioned: the other, by Takigawa (1971) described a patient with a chondroma in the scaphoid and lunate of the right wrist. We report two patients each with a chondr...
