Abstract：Objective To investigate the clinical effects of the volar anatomical locking plate and bone grafting in the treatment of the malunion of the distal radius. Methods From January 2013 to October 2016, 34 patients of malunion of the distal radius were treated by internal fixation with a volar anatomical locking plate and bone grafting. Among them, 15 patients were treated by allogeneic bone grafting ( Allogeneic Group ), while 19 patients with autologous bone grafting ( Autologous Group ). Preoperative and postoperative palm angle, ulnar deviation angle and radius height, fracture healing time, postoperative radial height loss rate, and postoperative Cooney function score of the wrist joint between the 2 groups were statistically analyzed. Results All the patients had primary healing after the operation. All the 34 patients were followed up ( 10.23 ± 5.29 ) months. The average fracture healing time was ( 3.52 ± 0.45 ) months. The fracture healing time: ( 3.75 ± 0.15 ) months in the Allograft Group; ( 3.47 ± 0.36 ) months in the Autogenous Group; no significant differences existed ( P > 0.05 ). The palm angle [ ( 7.3 ± 6.4 ) °, ( 7.1 ± 3.8 ) ° ], ulnar inclination [ ( 22.1 ± 5.7 ) °, ( 21.9 ± 4.2 ) ° ] and radial height [ ( 12.0 ± 3.3 ) mm, ( 12.7 ± 1.6 ) mm ] postoperation were significantly improved compared with the data preoperation, with statistical significance ( P < 0.01 ). However, there were no significant differences between the 2 groups at different stages ( P > 0.05 ). There were no significant differences in the rate of radial height loss and the wrist Cooney function score between the 2 groups 3 months postoperatively ( P > 0.05 ). Conclusions The treatment of malunion of the distal radius with bone grafting can enhance the reduction and fixation of the fracture, promote the healing of the fracture, reduce the postoperative reduction of the height of the radius and improve the function of the wrist. Demineralized bone matrix can replace autologous bone for bone grafting, avoiding the risk of bone surgery.
