Sinus tarsi approach in high-risk patients with displaced intra-articular calcaneus fractures: A case series

Abstract

PurposeThough research exists regarding calcaneal fractures, the treatment approach for displaced intra-articular calcaneal fractures (DIACF) remains controversial. The most common approach, the extensile lateral approach (ELA), for the treatment of DIACFs has high rates of wound complications reported. In contrast, the sinus tarsi approach (STA) is becoming more popular due to its minimally invasive technique. The objective of this retrospective study is to investigate the incidence of wound complications in high-risk patients with DIACF following operative fixation via the STA. MethodsFollowing IRB approval, a retrospective chart review was performed between 2007 and 2013 to assess high-risk patients for the presence of wound complications, including deep infections and delayed wound healing, following the use of STA for the management of DIACF's (n = 36). Demographics, risk factors, and secondary outcomes such as time to surgery were recorded. ResultsOf the 36 high-risk patients included in our study, seven had post-operative complications following operative fixation via the STA. Specifically, four patients had delayed wound healing, and three developed deep infections. Time to surgery had the greatest negative effect on postoperative complications and was influenced by age, sex, and the presence of a concomitant injury. ConclusionIn conclusion, this study demonstrates that the STA is a viable option for high-risk patients with displaced intra-articular fractures. Additionally, time to surgery should be minimized, when possible, to reduce risks of post-operative complications, including infections and delayed wound healing.
