Abstract:
Semiconstrained arthroplasty of the distal radioulnar joint (DRUJ) (Scheker prosthesis, Aptis Medical, Glenview, KY, USA) is a treatment option in case of irreparable destruction of the DRUJ. In our unit, a Scheker endoprosthesis was implanted in 5 wrists in 4 patients. 3/5 wrists (60%) in 3/4 patients (75%) underwent revision surgery. Reasons for revision surgery were implant loosening, periprosthetic fracture of the radius and suspicion of periprosthetic infection. Asymptomatic loosening of the screw of the radial head cover was detected in one wrist. Scheker arthroplasty is technically demanding. The prosthesis is prone to failure over the long term. Before implantation, all patients should be informed of the high risk of revision surgery.
