[Choice of operative procedures to correct equinus deformity in patients with cerebral palsy]

Equinus deformity of the foot presents a great number of difficulties to ambulant patients with cerebral palsy. Non-operative treatment of the incorrectible - fixed equinus is not successful. Many procedures are applied to treat it operatively, so its not clear which procedure at what age is the most successful. The purpose of this manuscript. is to clarify the issue. The results of four procedures are analyzed: aponeurectomny of m. gastrocnemius, Achilles tendon lengthening by z-plasty, a combination of these two procedures and sliding elongation of m. triceps surae. The analysis was based on 417 operations in 291 patients of the average age of 9 years (1-64). The average followup was 7 years. The assesment of the results was based on the visual evaluation of the gait, on pedoscope prints and on comparison of ankle movements before and after operation. The analysis shows that the best results were achieved by sliding elongation of m. triceps surae after the age of 7.
