  • Sinus tarsi approach combined with medial distraction technique for treatment of intra-articular calcaneus fractures

    ObjectiveTo discuss the effectiveness of limited open reduction via sinus tarsi approach using medial distraction technique in the treatment of intra-articular calcaneus fractures by comparing with open reduction and internal fixation via extensile L-shaped incision. MethodsA retrospective analysis was made on the clinical data of 21 patients with intra-articular calcaneus fractures treated by sinus tarsi approach combined with medial distraction technique between April 2013 and November 2014 (minimally invasive group), and 32 patients treated by extensile L-shaped incision approach between June 2012 and September 2014 (extensile incision group). No significant difference was found in gender, age, injury pattern, fracture classification, time from injury to operation, preoperative Böhler angle, Gissane angle, calcaneal varus angle, the ankle and hind-foot score of American Orthopaedic Foot and Ankle Society (AOFAS), and visual analogue scale (VAS) score between 2 groups (P>0.05), which was comparable. The operation time, wound complications, and bone healing time were recorded. The postoperative function was also evaluated by AOFAS score and VAS score. The pre-and post-operative Böhler angle, Gissane angle, and calcaneal varus angle were measured on the X-ray films, and the corrective angle was calculated. ResultsSixteen patients were followed up 6-18 months (mean, 11.5 months) in the minimally invasive group, and 23 patients for 6-24 months (mean, 13.5 months) in the extensile incision group. Difference was not significant in operation time between 2 groups (t=0.929, P=0.796). No complication occurred in the minimally invasive group; partial skin flap necrosis occurred in 3 cases of the extensile incision group, was cured after dressing change. There was no loosening of implants or reduction loss in 2 groups at last follow-up. Subtalar joint stiffness occurred in 1 case of the minimally invasive group and 4 cases of the extensile incision group, and 1 patient had discomfort for the implants in the extensile incision group. The bone healing time was (9.9±0.8) weeks in the minimally invasive group, and was (10.1±0.7) weeks in the extensile incision group, showing no significant difference (t=0.613, P=0.845). Böhler angle, Gissane angle, calcaneal varus angle, AOFAS score, and VAS score were significantly improved at last follow-up when compared with preoperative values in 2 groups (P < 0.05), but there was no significant difference between 2 groups (P>0.05), and the corrective value of angle showed no significant difference between 2 groups (P>0.05). ConclusionLimited open reduction via sinus tarsi approach for intra-articular calcaneus fractures could reduce the incidence of wound complications effectively. Meanwhile, the medial distraction technique is helpful to correct the heel varus deformity.
