Abstract
ObjectiveTo assess the long‐term outcomes after percutaneous reduction (PR) and screw fixation versus plate fixation via the sinus tarsi approach (STA) for displaced intra‐articular calcaneal fractures (DIACF).MethodsThis retrospective study included a total of 150 patients (June 2008–August 2011), comprising 85 men and 65 women (mean age, 38.4 years), who were assigned to the PR group or the STA group. The inclusion criteria were DIACF (>2 mm) including Sanders type II and III, closed fracture, unilateral fracture, no history of smoking or no smoking during hospitalization and 3 months after surgery, and follow‐up time not less than 8 years. The exclusion criteria were clear surgical contraindications (severe cardiovascular and cerebrovascular diseases), local or systemic infection symptoms, diagnosis with diabetes or lower extremity vascular disease, and Sanders type IV or open fractures. Outcomes were assessed by means of the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot scores, radiographic images, and postoperative complications.ResultsThe mean follow‐up period was 8.7 years (range, 8.0–10.0 years). The AOFAS scores in the PR group during the follow‐up period were 54.2 ± 5.1, 85.8 ± 4.0, 88.1 ± 3.8, 87.9 ± 3.6, 87.8 ± 3.9, 86.9 ± 3.9, respectively, and in the STA group were 55.0 ± 5.6, 84.5 ± 5.2, 87.1 ± 3.8, 86.9 ± 3.8, 87.7 ± 3.3, and 87.6 ± 2.8, respectively. There was no significant difference in AOFAS scores, Bohler's angle, Gissane's angle, calcaneal length, and height between the two groups (P > 0.05). The good to excellent rate of the PR group (80.8%) was less than that of the STA group (91.7%) (P = 0.055). For Sanders III fractures, the good to excellent rate of the PR group (33.3%) was less than that of the STA group (76.9%) (P = 0.029). For calcaneal width recovery, the STA group performed better than the PR group (P < 0.05). The incidence of postoperative complications in the PR group (12.8%) was lower than that in the STA group (27.8%) (P = 0.026), of which the incidence of wound complications was 3.8% in the PR group and 13.9% in the STA group (P = 0.041). In addition, there was no significant difference in other postoperative complications such as sural nerve injury, peroneus longus and brevis muscle injury, calcaneal valgus symptoms, lateral impingement symptoms, and subtalar arthritis (P > 0.05).ConclusionFrom the 8–10‐year follow‐up results of PR and STA as surgical procedures for the treatment of DIACF, it was found that there was no significant difference in the overall efficacy between them. STA was found to be superior to the PR in terms of the recovery of calcaneal width, providing more stable fixation for Sanders III fractures. PR was found to be more effective in reducing wound complications.

Summary
75% of calcaneal fractures are intraarticular fractures. Displaced intra-articular fractures of the calcaneus are disabling injuries that occur mostly in young, active, physical laborers and, have a high socioeconomic impact. Studies have demonstrated a decrease in the incidence of late consequences and the socioeconomic burden of these injuries when treated by ORIF5,6,9. Because the skin of the lateral calcaneal wall is thin and vulnerable to injury, wound complications remain a major concern[7]. These complications mainly include wound edge necrosis, dehiscence, hematoma, infection, and sural nerve injury[10,11,12,13]. It is reported that these methods effectively reduce the incidence of wound complications[19]
