RESUMO
BACKGROUND: Displaced intra-articular calcaneal fractures are challenging injuries, and there is debate regarding the best method of treatment. PATIENTS AND METHODS: Between 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. RESULTS: The 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. CONCLUSION: The 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.
