Management of Malunited Intra articular Fracture of the Calcaneous

Background and objectives to evaluate calcaneal malunion management through a salvage procedure consisting of combined subtalar joint fusion, calcaneal osteotomy, and lateral wall exostectomy with malunion type 3 according to Zwipp and Rammelt classification and follow up the outcome of their management. Methods 30 patients with complex intra-articular calcaneal malunion to assess the outcome of their management according to the deformity with subtalar deformity with or without calcaneal osteotomy after approval by the local ethical committee of the university. Results There was a statistically significant increase in the AOFAS score and FAAM score at 6 months and 1 year postoperative as compared to the preoperative value. Also, there was an increase in talocalcaneal height and a change in talar declination and lateral talocalcaneal angle at 6 months and 1 year postoperative. Conclusion The use of combined subtalar joint fusion, calcaneal osteotomy, and lateral wall exostectomy in correcting the malunited calcaneal fractures is associated with significant improvement without the occurrence of major complications.
