Abstract
Purpose
Hemiplegic cerebral palsy patient may present a shorten leg on the hemiplegic side that afflicts negatively the kinematic of the uninvolved limb. Thus, the aim of this study was to investigate the modification of gait kinematic after epiphysiodesis for limb equalization and secondary to verify the prediction of correction.
Methods
Skeletally immature hemiplegic patients with a minimum limb leg discrepancy (LLD) of 2.5 cm were treated with epiphysiodesis of the unaffected knee and clinically evaluated with Edinburgh visual gait score (EVGS). Green–Anderson curve was used to predict time decision for correction.
Results
Ten LLD patients were evaluated with the Edinburgh visual gait score (EVGS) before and after surgery. Mean age was 12.7 years, mean follow-up was 6.7 years, and mean LLD was 3.4 cm before surgery and 1.2 cm at final follow-up. After lower limb equalization surgery, improvement in gait kinematics was observed on both the uninvolved and hemiplegic limb of hemiplegic cerebral palsy patients (p < 0.001). Final correction did not reach expected correction (2.3 vs. 2.8 cm). However, the difference was not statistically significant (p = 0.058).
Conclusion
This is the first study to report improvement on both the uninvolved and hemiplegic limb gait kinematics after limb equalization surgery. Due to the impaired dorsiflexion of the hemiplegic foot, LLD target at the end of growth should range between 0.5 and 1.5 cm.
