Fixation techniques for split anterior tibialis transfer in spastic equinovarus feet.

Abstract

Equinovarus of the foot is the most common lower extremity deformity following traumatic brain injury. We evaluated outcomes of the split anterior tibialis tendon transfer (SPLATT) for correction of equinovarus in 47 patients with hemiplegic traumatic brain injury and specifically studied differences in outcomes with two tendon fixation techniques. Seventeen patients constituting Group I underwent fixation with one technique and 30 constituting Group II had another technique. Patients in both groups had appropriate procedures based on dynamic electromyography and gait analyses. Both groups were demographically comparable. All 47 feet were corrected to plantigrade position. Thirty-six of 47 patients became brace-free at final followup. There was a notable decrease in the use of ambulatory aids and ambulatory status improved in both groups. There were three fixation-related complications in Group I and none in Group II. Surgical correction of the spastic equinovarus with SPLATT, in the appropriate patient, with or without associated tendon procedures helps to achieve and maintain correction, improves the ambulatory status of the patient, and eliminates the need for bracing in as much as 77% of patients. We recommend the Group II construct owing to the considerably lower complication rate.
