Abstract

Background: Open hindfoot surgery is associated with a relatively high rate of complications, including neurovascular injuries and wound healing problems compared with percutaneous techniques. However, there is a scarcity of literature describing the outcomes of these percutaneous techniques given their relatively recent adoption. The present study aims to assess the rate of postoperative complications for 3 commonly performed percutaneous calcaneal osteotomies. Methods: One hundred eighteen patients (unilateral feet) were treated with one of 3 common percutaneous calcaneal osteotomies. Sixty-five patients (55.1%) were treated with a medializing calcaneal osteotomy for hindfoot valgus, 32 patients with a Zadek osteotomy (27.1%) for insertional Achilles tendinopathy, and 21 patients (17.8%) with a modified Dwyer osteotomy for hindfoot varus. Fisher exact test was used to assess for associations between categorical variables. Results: The mean age was 46.2 years and there was a mean follow-up of 16.1 months. The overall rate of postoperative complications was 3.4% (n = 4), and no significant differences were found between the different osteotomy types. Complications included 2 cases (1.7%) of transient neuritis, 1 case of prolonged wound drainage (0.8%), and 1 nonunion (0.8%). None of the complications were associated with any recorded preoperative comorbidity. Discussion: In this series, we found that percutaneous calcaneal osteotomies are a safe alternative method for the treatment of conditions involving the hindfoot. The rate of postoperative complications may be less when compared to the reported rates of open hindfoot correction and should be considered in patients with a traditionally high risk of developing a postoperative complication. Level of Evidence: Level IV, retrospective analysis.
