[Influence of intertrochanteric varisation osteotomy on the gait of children with Perthes disease].

BACKGROUND
The purpose of this study was to investigate possible effects of intertrochanteric varisation osteotomy on the gait of children with Perthes disease.


PATIENTS
Clinical and radiographic examinations and gait analysis were conducted on 50 children.


METHOD
Gait analysis was conducted using the GANGAS system.


RESULTS
Despite predominantly very good or good results shown by the clinical and radiographic examinations, gait analysis detected various functional deficits.


CONCLUSIONS
The examinations show that for the group of patients described, gait analysis is a valuable method of recording functional deficits and early recognition of the need for postoperative, physiotherapeutic treatment, thus helping to avoid chronificating alterations of the gait and, consequently, potential secondary damage.
