Minimally invasive K-wire fixation of displaced intraarticular calcaneal fractures through a minimal sinus tarsi approach

BackgroundDisplaced intra-articular calcaneal fractures are challenging injuries, and there is debate regarding the best method of treatment.Patients and methodsBetween January 2018 and January 2021, a prospective study was conducted on 46 patients with 56 displaced intraarticular calcaneal fractures that were treated with minimally invasive fixation using Kirschner wires (KWs) through the sinus tarsi approach.ResultsThe mean follow-up period was 22.36 months. The American Orthopaedic Foot and Ankle Society (AOFAS) score was adopted as a method of clinical evaluation; the mean AOFAS score was 78.4. All cases showed radiographic evidence of adequate healing, with no collapse till the final follow-up. Complications included persistent pain, subtalar arthritis, deep infection and superficial pin site infection.ConclusionThe use of the sinus tarsi approach and percutaneous KWs represents a minimally invasive approach which expands the indications of surgery for displaced intra-articular calcaneal fractures with fewer treatment-related complications.Level of evidence (4) case series.Trial registration This study has been approved by the ethical research committee of the Faculty of Medicine, Tanta University, under the code: 35901/10/22.
