Evaluation of the short-term results of closed reduction and percutaneous K-wires fixation of displaced intra-articular calcaneal fractures (DIACF).

PURPOSE: Optimum management of displaced intra-articular calcaneal fractures (DIACF) still controversial. Open surgery carries the risk of wound complications, while non-operative management has a high incidence of arthrosis. To avoid these complications, minimally invasive and percutaneous fixation was introduced. The purpose of this study was to prospectively evaluate the short term clinical and radiological outcomes after closed reduction and percutaneous fixation of DIACF using K-wires.

PATIENTS AND METHODS: Outcomes of twenty patients were evaluated at the final follow up. A functional assessment using the AOFAS scoring system. Radiological parameters recorded included three angles (Böhler's, Gissane and posterior facet inclination angles) and three distances (calcaneal length, height and width). Any complications were reported at any follow-up.

RESULTS: The mean patient's age was 33 ± 15.2 years, 8 (40%) patients with type II fractures, 10 (50%) patients with type III fractures, and 2 (10%) with type IV fracture according to Sanders classification. After a mean follow-up of 9 months, the mean AOFAS score was 84, excellent in 9 patients (45%), good in 9 (45%), and fair in 2 (10%). At the final follow-up the Böhler's angle, Gissane angle and PFIA was 25.1° ± (5.2), 119.9° ± (9.4) and 51.7° ± (5.9) respectively and the calcaneal height, length and width was 41.8 mm ± (2.1), 75.1 mm ± (3.01) and 40.9 mm ± (2.6) respectively. We had no cases of deep infection, 20% had significant subtalar arthritis.

CONCLUSION: The closed reduction and percutaneous fixation technique for DIACF management offered acceptable clinical and radiographic outcomes, with fewer complications when compared to other management options.
