Minimally Invasive Arthroscopic-Assisted Reduction with Percutaneous Fixation in the Management of Intra-Articular Calcaneal Fractures: A Review of 24 Cases

Abstract

A retrospective analysis of 24 cases of minimally invasive, open reduction, and internal fixation of intra-articular calcaneal fractures is presented. Collected data included articular step-off, medial wall displacement, and Boehler's angle, in addition to other descriptive characteristics of the fracture and case series. The operative technique is described in detail including the optimal screw constructs. Arthroscopic assistance was used in 10 of the cases. The articular step-off of the posterior facet, medial wall displacement, and Boehler's angle all displayed statistically significant change between the preoperative and postoperative periods (P < .0001). These results were consistent with the goal of restoration of articular congruity, calcaneal morphology, and calcaneal height. There were no soft tissue complications. The mean overall follow-up duration was 2.8 years (range 1 to 10 years). Of the 18 patients who were followed for more than 1 year (range 1.0 to 10 years), none went on to subtalar fusion. The results of this study suggest that a minimally invasive approach can improve radiographic parameters consistent with the ultimate goals of operative reduction of calcaneal fractures, and can be used to achieve satisfactory results with minimal risk of wound complication. 4.
