Abstract

Complex multiplanar ankle/foot deformity as equinocavovarus is a common problem in patients with spastic cerebral palsy hemiparesis. The data from 30 consecutive patients (30 feet), treated between March 2009 and March 2010, with equinocavovarus and toe clawing secondary to spastic cerebral palsy hemiparesis, aged 16 to 18 years, were analyzed clinically and radiographically. All the patients had received conservative physiotherapy treatment and ankle/foot orthoses before undergoing combined soft tissue and bony surgical procedures performed in a single session to correct the complex toe clawing, cavus, varus, and equinus deformities. Preoperative measurements of certain foot angles were compared with their corresponding postoperative values. A grading system for evaluation of the results using a point scoring system was used to accurately evaluate both the clinical and the radiographic results after an average follow-up period of 2.5 years. Of the 30 patients (30 feet), 18 (60%) had excellent, 9 (30%) good, 3 (10%) fair, and 0 had poor outcomes. Neither vascular problems nor nonunion occurred. Significant improvement was seen postoperatively (p < .0333). Neither staged surgical procedures nor gradual distraction techniques using external fixators are ideal modalities to correct complex ankle/foot equinocavovarus deformity in patients with spastic cerebral palsy. Single-event, multilevel surgery with complete soft tissue and bony correction appears to be the treatment of choice in such cases. It shortens the treatment period and avoids patient dissatisfaction associated with multiple procedures, without major complications.
