Application of a Constrained External Fixator Frame for Treatment of a Fixed Equinus Contracture

Ankle equinus can result from congenital, traumatic, neurological, and pathological etiologies. Corrective methods have been described in the literature using a combination of soft tissue releases or osseous procedures with reported complications. We present a case report of a patient with a post-traumatic fixed equinus deformity of 28° at maximum dorsiflexion, treated successfully through gradual correction using a modified constrained external fixator. The patient maintained a rectus foot and was able to perform all daily activities at the final follow-up. Fixed equinus deformities can be difficult to manage. Gradual correction with an external fixator is a reasonable treatment option. Level of Clinical Evidence: 4
