BACKGROUND: The therapeutic regimen of intraarticular calcaneal comminuted fractures commonly selects plate and screw fixation. However, for case of posterosuperior calcaneal fracture, the weakness of achilles tendon stretch and plate screw fixation results in difficulty or maintenance of reduction. OBJECTIVE: To investigate the therapeutic effects of open reduction and internal fixation with steel screw and Steinmann pins for comminuted calcaneal intra-articular and posterosuperior fractures. METHODS: From December 2009 to December 2013, forty patients with fractures of comminuted calcaneal posterosuperior fractures were randomly divided into two groups. In the control group, patients were treated by open reduction and internal fixation by plate screw only. In the experimental group, patients were treated by open reduction and internal fixation by combination of plate screw and Steinmann pin. The Gissane and Bohler angles of the calcaneus were measured from lateral radiograph before and 4 weeks after surgery, and the MARYLAND score was assessed at the last follow-up. Gissane and Bohler angle and MARYLAND score were compared in each group and among different groups. RESULTS AND CONCLUSION: All patients were followed up for 9-23 months. BOHLER and GISSANE angles were significantly bigger at 4 weeks after surgery compared with pre-treatment in both groups (P < 0.05). BOHLER and GISSANE angles were significantly bigger in the experimental group than in the control group at 4 weeks after surgery (P < 0.05). During final follow-up, the average score by MARYLAND Foot Score was 78 in the experimental group and 67 in control group, with their excellent and good rate of 80% and 73%. The excellent and good rate was significantly higher in the experimental group than in the control group (P < 0.05). These data indicated that open reduction and internal fixation with combination of plate screw and Steinmann pin has better efficacy in treatment of the comminuted calcaneal intra-articular and posterosuperior fractures compared with plate and screw fixation alone. Their fixation is firm. Functional exercise can be performed earlier. Postoperative recovery of function of the affected limbs is better than plate and screw fixation alone. © 2014 Journal of Clinical Rehabilitative Tissue Engineering Research. All rights reserved.
