Abstract

PURPOSE
To understand the relationship between the gait patterns in transverse plane and the transverse plane deformities. MATERIALS AND METHODS: We evaluated the clinical, radiological, and three-dimensional gait analysis data of 152 spastic diplegics with transverse plane deformities. We define the transverse plane deformities as follows: 1) femoral anteversion > or =30 degrees, 2) thigh foot angle < or =-5 degrees or > or =25 degrees, 3) severe foot deformities that could affect the foot progression angle. RESULTS: We classified gait patterns of spastic diplegics into 6 groups on the base of pelvic compensation and foot progression angle, and divided anatomic characteristics into symmetric and asymmetric type. Among the gait patterns, pattern I-A (in-toeing with pelvic compensation) and II-A (in-toeing without pelvic compensation) were most prevalent. Femoral antetorsion was the most frequent torsional deformities, whereas valgus of foot was second most. CONCLUSION: We classified the gait patterns and analyzed the relationship between each gait pattern and types of torsional deformities.
