Purpose: The purpose of this study is to analyze the clinical and radiological results of minimally invasive percutaneous screw fixation in intra-articular calcaneal fractures and its complications.
Materials and Methods: This study is based on 30 intra-articular calcaneal fractures that treated by index operation from June 2005 to November 2006 with at least 6 months follow-up. We assessed the clinical and radiological outcomes and complications.
Results: According to Sanders classification, there were 8 in type IIA , 7 in type IIB, 3 in type IIIAB, 6 in type IIIBC, 6 in type IV. And according to Essex-Lopresti classification, there were 9 in the tongue type, 21 in the joint depression type. Average follow-up period was 14.6 months (range: 6-23 months). Average interval between from injury to operation was 2.3 days. Average AOFAS score was 87.7 (range: 52-92). Satisfactory results were obtained in 22 cases (73.3%) by AOFAS score and in 20 cases (66.7%) by VAS score (mean: 3.4). Radiological results improved from 8.7 to 20.3 degrees in the Bohler angle and from 40.2 mm to 52.1 mm in calcaneal height. Postoperative complications were 2 skin and soft tissue problems and 1 sural neuropathy.
Conclusion: Minimally invasive percutaneous screw fixation may be useful alternative surgical method in the management of Sanders type II and III calcaneal fractures, which is possible to achieves the anatomical restoration and minimizes postoperative complication in patients with high risks of soft tissue compromise and allows relatively early operation.
