The Mini Bone Extra-articular Reconstruction System for Progressive Collapsing Foot Deformity—Surgical Technique With Cadaveric Quantification of Surrounding Anatomy

Abstract

We present a novel surgical technique, the mini Bone Extra-articular Reconstruction (BEAR) system, that involves minimally invasive all BEAR systems. The surgical technique was used to perform the medial displacement calcaneal osteotomy, Evans osteotomy, and Cotton osteotomy on 9 cadaveric feet under fluoroscopic guidance. We also present a case series of patients who have undergone the procedure. We first carefully dissected the sural nerve, superficial peroneal nerve, and its branches from each cadaveric foot and evaluated injuries following the mini-BEAR osteotomy cuts. We then measured and recorded the distance between the osteotomy cuts and these anatomic structures. We believe that this technique can potentially replace the multiple long surgical incisions with minimal ones. Level of Evidence: Level IV.
