Intra Articular Calcaneal Fracture with Subtaler Joint Depression: Minimally Invasive Sinus Tarsi Approach for Open Reduction and Internal Fixation

Abstract

Background Numerous studies have demonstrated that fractures of the calcaneum, which account for a significant fraction of major tarsal bone fractures, are linked to severe and protracted impairment. This study aimed to evaluate minimally invasive sinus tarsi approach (STA) for open reduction and internal fixation of calcaneal fracture with joint depression to clarify and identify it benefits and drawbacks. Methods This prospective cohort research was performed on all adult cases with a displaced intra articular calcaneus fracture who were admitted to our institution. Patients aged of 14 to 60 years with unilateral, isolated, uncomplicated fractures were included. Results Our study conducted on 31patients with 34 fractures with a mean age of 34 years (type II 47% and type III 53%). The mean duration of follow-up was 20.45 months, the mean American orthopaedic foot and ankle society was 91.38% and the mean Maryland foot score was 94.79%. Pain and discomfort" were reported by 14 patients in regards to their foot. Seven individuals were found to have soreness at the locations of the posterior screws. The remaining 7 cases were identified as having complex regional pain syndrome, which is characterised by persistent foot pain, particularly when bearing weight. Sural nerve dystrophy was the only patient's complaint. One patient exhibited slight toe clawing. Conclusion The STA is a minimally invasive intervention utilised in the treatment of calcaneal fractures. It enables anatomic reduction of articular surfaces and allows for a clear view of the fracture.
