The surgical treatment of inveterate hip dislocation in children affected with cerebral palsy: a preliminary report.

The incidence of hip dislocation in patients affected with cerebral palsy is directly correlated with the degree of neurologic deficit. Surgical treatment aimed at stabilization of the coxofemoral joint relieves pain and avoids the occurrence of changes in the static of the pelvis and vertebral column. The authors report their experience with procedures for the recovery of joint congruency (release of the adductors and psoas, surgical reduction of the dislocated epiphysis, femoral shortening associated with varus-derotation at the osteotomy level, acetabuloplasty) performed in one or more surgical stages, and operations with a purely anthalgic purpose (innominate osteotomy according to Chiari), specifying relative indications in relation to age.
