Abstract:
Objective To investigate the anatomical features, operative method and efficacy of internal fixation in the treatment of iutra-articular fractures of caleaneum via the sinus tarsi approach. Methods The pathway, branches distribution and anastomosis of perforating descending branch of peroneal artery were observed on 18 adult cadaveric lower limbs. A sinus tarsi approach was designed. From July 2001 to January 2008, 71 intra-articular calcaneal fractures in 68 patients were treated with open reduction and internal fixation via sinus tarsi approach at lateral sides of calcaneus. According to the Sanders classification, there were 26 type Ⅱ fractures, 32 type Ⅲ fractures and 13 type Ⅳ fractures. Results All patients were followed up for a mean period of 39.3 months (13-85 months), and the fractures were completely healed. There was a significant difference in the length, width and height of the calcaneus, Bohler angle and Gissane angle before and after operation (P < 0.01). According to Maryland Foot Score, the operative effect was excellent in 33 feet, good in 29 feet, fair in 6 feet and poor in 3 feet. Conclusion Open reduction and internal fixation via sinus tarsi approach is an effective method for minimally invasive treatment of intraarticular fractures of the calcaneus, with the advantages of good clinical results and causing minimal damage to soft tissues.
