Correlation of technical surgical goals to the GDI and investigation of post-operative GDI change in children with cerebral palsy.

Aim: The purpose of this study was to introduce a standardized set of surgical technical achievement goals (TAGs) as part of a comprehensive outcome assessment model for children with spastic cerebral palsy (CP) undergoing orthopaedic surgical intervention to improve gait. Examination of relationships of these surgical goals to the Gait Deviation Index (GDI) and use of two assessments in tandem provided a thorough picture of technical surgical outcomes. This study also investigated changes in GDI in children with spastic CP after surgery.

The use of dynamic EMG in predicting the outcome of split posterior tibial tendon transfers in spastic hemiplegia.

The purpose of this study was to assess the outcome of split posterior tibial tendon transfers in patients with spastic cerebral palsy to determine whether the use of preoperative dynamic electromyography was predictive of surgical success. The study is a consecutive case series of 25 children with spastic hemiplegia who underwent unilateral split posterior tibial tendon transfers for varus foot deformities. Three patients were considered failures because of residual varus, which required further surgery.

Rectus and hamstring surgery in cerebral palsy: a gait analysis study of results by functional ambulation level.

The purpose of this study is to determine if children more severely involved with cerebral palsy respond as well to rectus transfer and hamstring surgery as those with less severe involvement. Ninety-nine children were classified as independent community ambulators, crutch/walker-dependent community ambulators, or household/exercise ambulators. Maximum knee extension in stance and total range of knee motion in gait increased following surgery in all groups.
