| Summary: | Category: Hindfoot Introduction/Purpose: The operative treatment of calcaneal fractures has been a controversial topic. Open reduction and internal fixation is associated with a high incidence of postoperative soft tissue complications. Closed reduction and percutaneous K-wires fixation was used to preserve soft tissue. The aim of our study is to evaluate the outcome of closed reduction and percutaneous K-wires fixation of displaced intra-articular calcaneal fractures. Methods: Twenty two displaced intra-articular calcaneal fractures were treated by closed reduction and percutaneous K-wires fixation. The clinical evaluation was based on Maryland Foot Score. According to Sander’s Classification, Eleven fractures were type II, nine were type III and two were type IV. Bimanual compression across the calcaneus was applied to reduce the calcaneal width. A Schanz screw was inserted into the calcaneal tuberosity and was forcibly pushed downwards to elevate the depressed fragment. Two parallel 2 mm K-wires were placed from the posterior inferior corner of the calcaneus across the posterior facet and into the talar body. The reduction of the articular surface was maintained by two crossing subchondral 2 mm K-wires. If the reduction was not satisfactory, a 1-2 cm long transverse incision was used just below the tip of the lateral malleolus. A small tipped periosteal elevator was introduced to elevate the depressed fragment before K-wire fixation. Results: The mean follow up period was 7.68 months. The clinical outcome revealed 18 fractures (81.8%) of satisfactory (14 excellent and 4 good), and 4 patients (18.2%) of unsatisfactory results (4 fair and 0 poor). The mean time of radiological union was 11.86 (range 10 – 14) weeks. One patient had pin tract infection. One patient developed heel widening. Conclusion: Closed reduction and percutaneous K-wires fixation of calcaneal fractures minimizes the soft tissue complications and postoperative scar formation. The mini approach for elevation of the depressed posterior facet restores the articular surface and decreases late subtalar arthritis.
