Abstract

The distal ulna has always been considered to be expendable and its removal has been advocated for a variety of post-traumatic degenerative and oncological conditions but recent studies showed that the distal radioulnar joint allows supination and protonation of the forearm and is important to one's grip strength and lifting ability. Several prosthesis models have already been made to replace the mechanical functionality of the distal radioulnar joint. We present two cases of females aged 22 and 12 years, respectively, who presented with wrist pain and swelling without any history of trauma and with terminal degree limitation in wrist movements due to tenderness and swelling. Both of them did not have any distant metastasis upon radiographic staging. The skeletally mature patient underwent radical excision of the distal ulnar osteosarcoma and received a distal radioulnar joint replacement prosthesis (Scheker prosthesis). The other skeletally immature patient underwent radical excision of the involved distal ulnar osteosarcoma with stabilization of the residual ulnar stump using the extensor carpi ulnaris sling in a modified version of the Goldner and Hayes technique. Both of our patients were treated according to the protocols ...Continue Reading
