Radiographic and functional outcome of operated closed intra-articular fractures of calcaneum: a retrospective analysis

Background: The present study aims to analyse the results of surgical outcome of the operated calcaneal fractures using either plates or cannulated cancellous screws. Recently there has been considerable shift of treatment of calcaneal fractures from conservative to operative owing to better understanding of fracture pattern. However, reduction of long-term functional outcome of such patients is always questionable and remains unanswered. Methods: A 25 fractures were operated with locking plates or cannulated screws after proper assessment. Functional assessment was done using AOFAS scoring system. Radiological outcome was assessed using restoration of Bohler and Gissane angle. Results: The results were extrapolated as excellent in 20 patients, good in 3 patient's and poor result in 2 patients. Statistical analysis revealed better outcomes in percutaneous cannulated screw fixation as compared to open plate fixation.  6 patients had to undergo implant exit of which 5 were cannulated screw backout, prominence irritating the soft tissue and 1 plate removal had to be done because of infection. None of the patients had subtalar arthritis, heel pad problems, peroneal tendinitis or implant failure. Conclusions: Surgical management in the treatment of choice for intra articular calcaneal fractures after thorough evaluation. The choice of implant depends upon the communition of fracture, soft tissue compromise, joint surface incongruity and surgical expertise. Radiological maintenance of Bohler and Gissane angle intraoperatively and at follow up is a good indicator for predicting functional outcomes score.
