Unicompartmental isoelastic resurfacing prosthesis for malignant tumor of the distal radius: A case report with a 3-year follow-up

We report a case of 74-year-old man in whom a unicompartmental isoelastic resurfacing prosthesis was used to reconstruct the distal radius after en-bloc resection of a malignant tumor. Thirty-nine months after the operation, on a visual analogic scale, pain score was 0110 and range of motion was 25 degrees of flexion, 5 of extension, 70 of pronation, 45 of supination, 20 of radial deviation, and 30 of ulnar deviation. The Quick DASH functional score was 72.72/100. With radiographic finding, the prosthesis was well-aligned, with no evidence of loosening but with slightly implant conflict with the lunate. This case report indicates that unicompartmental isoelastic resurfacing prosthesis seems a simple and reliable technique for distal radius reconstruction after en-bloc resection of malignant tumor.
