Disassembly of a Howmedica Modular Resection system
Ryotaro Nabeyama; Shuichi Matsuda; Kazuhiro Tanaka; Yukihide IwamotoKnee
We report the postoperative disassociation of a Morse taper junction of a Howmedica Modular Resection system implanted after the resection of a malignant distal femoral bone tumor. The disassembly occurred without apparent trauma. This complication was managed by closed reduction under epidural anesthesia. This disassembly probably occurred because of decreased tension of the soft tissue around the prosthesis or an impaired locking mechanism.
