Kuhlmann vascularized bone grafting for treatment of Kienböck's disease: a case report
نویسندگان
چکیده
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 vascularized bone graft for Kienböck's disease. In addition, the indications, contraindications, and outcomes are described.

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...

Kienböck, a German radiologist, described avascular necrosis of the lunate (Kienböck's disease) in 1910. The epidemiology and etiology are not well-known and always has been debated. A negative ulnar variance is considered as a predisposing factor for Kienböck's disease by the majority of the authors. The treatment depends upon the stage of the disease at the time of presentation and diagnosis....

The aim of this study was to compare two surgery methods including radial shortening and radial shortening combined with vascularized bone graft for treatment of stage II or IIIa of Kienböck's disease. It is a randomized, controlled clinical trial, which was carried out in 2011-2013. Twenty-four patients were assigned equally to radial shortening group (A) or radial shortening combined with vas...
متن کاملVascularized bone grafts for the treatment of carpal bone pathology.
Primary bone healing fails to occur in 5-15 % of scaphoid bones that undergo fracture fixation. Untreated, occult fractures result in nonunion up to 12 % of the time. Conventional bone grafting is the accepted management in the treatment algorithm of scaphoid nonunion if the proximal pole is vascularized. Osteonecrosis of the proximal scaphoid pole intuitively suggests a need for transfer of th...
