Abstract
This article summarises a comparative retrospective study (1983–2001) of 42 consecutive spastic–diplegic ambulatory patients (aged 2–10 years) by examining the radiographic and clinical results of two soft-tissue procedures for paralytic hip subluxation (PSH). Group A comprised 20 patients (26 PSHs) who were treated by iliopsoas tenotomy, and group B comprised 22 patients (31 PSHs) who were treated by rectus femoris and iliopsoas tenotomy with iliac crest resection (sartorius release). All patients had bilateral adductor tenotomies. At 8.8 years mean follow-up, group A migration percentages (MP) improved from 39.8% to 24.7% with 92.3% good/average results. At a mean follow-up period of 8.3 years, group B improved from 58.0% to 25.9% with 96.8% good/average results. Long-term hip reduction was achieved in 84.6% of group A and 80.6% of group B hips. Relative MP correction was superior in group B. No patient had MP progression in either the PSH or non-PSH hip. Walking ability improved in 55% of group A and 86% of group B patients (Functional Mobility Scale). In conclusion, we recommend release of all the principle hip flexors: rectus femoris, sartorius, and iliopsoas, coupled with adductor tenotomies, in this patient group.
Résumé
Une comparative rétrospective de 42 patients diplégiques spatiques mais ambulatoirs âgés de 2 à 10 ans a été réalisée entre 1983 et 2001 avec évaluation des résultats. Deux techniques de libération tissulaire étant pratiquées devant l’existence d’une sub-luxation paralytique de la hanche. Le groupe A (20 patients, 26 hanches PSHs) ont été traités par ténotomie de l’iliopsoas, dans le groupe B 22 patients, 31 PSHs ont été traités par ténotomie du droit antérieur, de l’iliopsoas avec résection de la crête iliaque libérant le sartorius. Tous les patients ont bénéficié également d’une ténotomie bilatérale des adducteurs. À 8,8 ans de suivi, dans le groupe A, le pourcentage de migration de la tête MP est amélioré de 39,8% à 24,7% avec 92,3% de bons résultats en moyenne alors que dans le groupe B, à 8,3 ans la sub-luxation est améliorée de 58,0% à 25,9% avec 96,8% de bons résultats. La réduction de la hanche est obtenue dans 84,6% des cas du groupe A et 80,6% des cas du groupe B. La correction de la migration de la tête est supérieure dans le groupe B, aucun patient n’a vu sa migration augmenter. La marche a été améliorée de 55% dans le groupe A, à 86% dans le groupe B. Nous recommandons la libération de tous les muscles fléchisseurs de la hanche: droit antérieur, sartorius, iliopsoas en association avec une ténotomie des adducteurs chez ce type de patients.
