Conservative versus operative treatment for Kienböck's disease. A retrospective study

In this retrospective study on Kienböck's disease, a comparison was made between 21 cases operated on by various techniques and 22 cases treated conservatively, with a mean follow-up of 65 months. Operative management of the disease did not show any superiority over conservative treatment. Moreover, surgery was responsible for a loss of mobility of 24%, and for a change in social activities in about a quarter of the patients, while grip strength was only slightly improved. Surgical indications for Kienböck's disease should be carefully considered, keeping in mind their side-effects, and the relative benignity in some cases of the natural course of the disease.
