Abstract:
BACKGROUND: Forceful fixation and enough blood supply in fracture site are the fundament for treating bone nonunion. OBJECTIVE: To investigate the outcome of autologous iliac bone-grafting and plate fixation in treatment of the ununited distal ulnar fracture with osseous defects. DESIGN, TIME AND SETTING: The own control study was performed at the Department of Orthopaedics, Sixth People’s Hospital, Shanghai Jiao Tong University from August 2002 to May 2006. PARTICIPANTS: Of 21 cases of the ununited distal ulnar fracture with osseous defects, 13 cases were induced by ulnar and radial fracture, and 8 cases were induced by ulnar fracture. There were 15 cases of open fracture and 6 cases of closed fractureof first onset. Bone defects were 1.5 cm-5.0 cm, averagely 3.1 cm. METHODS: Bone defects were filled with intercalary iliac grafts. Length and axial ray of ulna were controlled. Ulna was fixed utilizing 5-8 wells 1/3 tubular plate, reconstruction plate or locking compression plate. At least two screws were used at the distaend, and 3 or 4 screws were fixed in the proximal end. Follow-up was conducted once per month to observe clinical appearanceand radiograph in each patient. MAIN OUTCOME MEASURES: Fracture nonunion, dorsal extension and palmer flexion of wrist joint, pronation and supination othe forearm were measured. RESULTS: All 21 cases were followed up for a mean time of 14.7 months. All the patients obtained bony union, and a mean timof 4.6 months (ranged 3 to 7 months). The distal ulnar healed with
