ABSTRACT
Introduction:
Calcaneal fractures are rare injuries constituting 2% of all fractures. Fractures of calcaneum correspond to nearly 60-75% of the tarsal bone fractures. The calcaneum is the most commonly fractured tarsal bone 90% occur in males between 21 and 45 years of age. The calcaneal fracture may be extra-articular (sparing the subtalar joint) and intra-articular involving the subtalar joint. Intra-articular fractures account for approximately 75% of calcaneal fractures and have been associated with poor functional outcomes. In this study, we aim to assess the functional outcome of internal fixation in displaced intra-articular calcaneal fractures. Materials andMethods:
A prospective interventional study was conducted on patients with only intra-articular calcaneal fractures admitted to Chettinad Hospital and Research Institute, Kelambakkam during the period from May 1, 2022, to February 29, 2024, and a total of 32 patients were considered. The functional outcome was assessed by the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scoring System.Results:
The average age of the patients in our study was 39 years of which all were male. Fall from height is the most common mode of injury. The right calcaneum is more commonly involved than the left. The mean duration of hospital stay was around 10 days. The fracture classification was based on the sanders and Essex-Lopresti classification of which 17 patients were sanders type 3 and 13 patients were sanders type 2 and 1 patient was sanders type 4. The mean time for radiological union is 12 weeks. The Bohler's angle and Gissane's angle preoperatively 16.16 ± 8.87 and 121.48 ± 7.47 restored to near normal values after fixation 27.77 ± 6.02 and 113.485 ± 44, respectively. Heel height and heel width restored to near normal values of (pre-operative heel height - 24.74 ± 3.71 and heel width - 39.97 ± 4.11 and post-operative heel height - 31.55 ± 3.38 and heel width - 34.0 ± 3.1), respectively. The most common complications were wound-related complications (superficial wound infection - 9.7%, deep wound infection - 3.2%, and wound margin necrosis and wound dehiscence 6.4%) and the most common late complications were complex regional pain syndrome - 9.7% and subfibular lateral impingement with peroneal tendinitis - 6.5%. AOFAS grading of functional outcome had shown good to excellent results in 83.8% (26 patients) of the cases. The mean AOFAS score was 83.39 in our study.Conclusion:
The present study shows that open reduction and internal fixation give superior radiographic results as shown by the restoration of Bohler's and Gissane's angle and height and width of the calcaneus to near normal values, indicating anatomical restoration of calcaneal shape. The functional outcome by AOFAS score showed good to excellent results in most of the patients with minimal wound complications.
