[Evaluation of the functional results in the treatment of pelvic limbs with multiple level surgery in spastic ICP patients].

UNLABELLED The purpose of this study is to assess the effects of multiple level surgery of the pelvic limbs in patients with spastic infantile cerebral palsy seen at the National Rehabilitation Institute and show that their clinical improvement is comparable to the reports in the national and international literature. MATERIAL AND METHODS This is a longitudinal, prospective, descriptive, self-controlled, before-and-after clinical trial that included patients with spastic infantile cerebral palsy who underwent multiple-level single-stage surgery from January 2007 to August 2008. The inclusion criteria were as follows: both genders, ages 4 to 16 years, with a complete clinical file, with preoperative and 8-12 month postoperative rehabilitation. Elimination criterion: any event not related with multiple-level surgery. Exclusion criterion: any surgeries prior to admission. A descriptive statistical analysis was used, together with the Student t-test and the chi-square test. RESULTS 81 patients with a mean age of 7 +/- 3.2, an age range of 4-16 years; 60.5% males and 39.5% females. The subtypes of spastic infantile cerebral palsy were as follows: biparesis 64.2%, quadriparesis 22.2%, hemiparesis 8.6%, double hemiparesis 4.9%. The clinical-surgical classification (14) changed as a result of improvement and according to the number of surgical procedures: 6 patients (7.4%) had significant improvement (p = 0.13) with one procedure; 44 patients (54.3%) had significant improvement (p = 0.002) with two procedures; 28 patients (34.6%) had significant improvement (p = 0.04) with three procedures, and 3 patients (3.7%) had significant improvement (p = 0.19) with four procedures. On the other hand, when the number of surgical procedures was related with the diagnostic subtype of spastic infantile cerebral palsy, in those undergoing one procedure the clinical-surgical classification did not change in the cases of biparesis (p = 0.26), hemiparesis (p = 0.18), and double hemiparesis (p = 0.50). In those undergoing two surgical procedures the significant changes occurred for the cases of biparesis (p = 0.20), quadriparesis (p = 0.007), and double hemiparesis (p = 0.16). In those undergoing four procedures no changes occurred in the cases of biparesis (p = 0.26) and hemiparesis (p = 0.50). DISCUSSION An improvement in the clinical-surgical classification was observed (p = 0.0001) based on the results of Gazi Zorer, as well as a significant improvement (p < 0.001) and an improvement reported by the gait analysis by the following authors: Ugur Sayli, Gouth, MA Khan.
