Anatomical reconstruction of the spring ligament complex: "internal brace" augmentation.

The calcaneonavicular (spring) ligament complex is a critical static support of the medial arch of the foot. Compromise of this structure has been implicated as a primary causative factor of talar derotation leading to the clinical deformity of peritalar subluxation. Few procedures have been described to address this deficiency. The technique we describe here is a simple yet effective method to reconstruct the spring ligament complex that can easily be used in conjunction with other more commonly used procedures for extra-articular reconstructions of this deformity. We believe this procedure allows for a more powerful deformity correction and may decrease dependency on other nonanatomic reconstructive procedures.
