Case Report of Modified Sauvé-Kapandji Technique Using Endobutton Suture in Secondary Treatment of Madelung Deformity

The Sauvé-Kapandji technique is considered a useful treatment option for distal radioulnar joint instability encountered in many conditions, such as Madelung deformity or in post-traumatic entities. However, post-operative instability of the proximal ulnar stump and radioulnar convergence may be symptomatic and is still a major concern. Despite proximal ulnar stump stabilization with various techniques, many patients still complain of pain and limitation of wrist movement. We report a case of a patient with Madelung disease treated initially by corrective radial and ulnar osteotomy, and then encountered a post-traumatic distal radioulnar joint instability. This condition was treated with a modified Sauvé-Kapandji procedure using a single endobutton suture, leading to good clinical and radiological results.
