ABSTRACT
The single event multilevel surgery (SEMLS) is a procedure preferably for patients with cerebral palsy (CP), including several orthopedic surgeries in one surgical time, and involves at least two levels joints of lower extremities, seeking to optimize gait. It is based on biomechanical principles provided by the gait lab (GL). Objective: To evaluate the impact of SEMLS in the gait of patients with CP spastic diplegia, one year after surgery. Patients and Methods: Retrospective study with review of medical records of 61 patients undergoing SEMLS. 23 out of 61 subjects accomplished the inclusion criteria. GL data before and after surgery was summarized in Gait deviation index (GDI), cadence and velocity, as well as functional mobility scale (FMS). Patients were categorized in two groups according to the Gross motor function classification system (GMFCS) as A for I-II GMFCS and B for III GMFCS. Statistical comparison was performed using Wilcoxon test. Results: The average SEMLS include 6.19 procedures per patient. Overall, significant variations in GDI (p < 0.0001) and cadence (p < 0.007) were found. In the subgroup A, there were significant changes in all GL variables (p < 0.009). In subgroup B, a significant effect was only found for GDI. Although FMS showed improvement, it was not statistically significant for 50 m and 500 m, in both subgroups and the total population (14 patients). Conclusion: Significant improvement was seen in CP spastic diplegic patients, for both cadence and GDI after one year SEMLS, particularly in the subgroup with independent walking...
La cirugía multinivel (CMN), es un procedimiento usado preferentemente en pacientes con parálisis cerebral (PC) que reúne varias cirugías ortopédicas en un tiempo quirúrgico involucrando como mínimo dos niveles articulares de extremidades inferiores, buscando optimizar la marcha. Se basa en principios biomecánicos aportados por el laboratorio de marcha (LM). Objetivo: Evaluar el impacto de CMN en la marcha de pacientes con PC tipo diplejía espástica, a un año postcirugía. Pacientes y Método: Estudio de cohorte única, retrospectivo. Se revisaron fichas de 61 pacientes intervenidos con CMN, 23 cumplieron los criterios de inclusión. Se obtuvo datos de LM pre y a un año postoperatorio, resumidos en cadencia del paso, velocidad, Gait Deviation Index (GDI), y Functional Mobility Scale (FMS); los sujetos se dividieron en subgrupos: A con Gross Motor Function Clasification System (GMFCS) I-II y B con GMFCS III. Se realizó comparación estadística mediante test de Wilcoxon con p < 0,05. Resultados: En promedio se realizaron 6,19 procedimientos quirúrgicos por paciente. En el grupo total se obtuvo variaciones significativas en GDI (p < 0,0001) y cadencia (p < 0,007). En el subgrupo A hay variaciones significativas en todas las variables de marcha (p < 0,009). En subgrupo B hay variaciones significativas sólo en GDI. Para la escala FMS existió mejoría, sin significancia estadística en 50 m y 500 m, en los 14 pacientes examinados y en los subgrupos. Conclusión: Se observa mejoría en la marcha de pacientes PC tipo diplejía espástica, en cadencia y GDI, tras un año post CMN, particularmente en el subgrupo A, con marcha independiente...

Because complications are more common in patients with cerebral palsy (CP), surgeons and anesthesiologists must be aware of perioperative morbidity and be prepared to recognize and treat perioperative complications. This study aimed to determine the incidence of and risk factors for perioperative complications of orthopedic surgery on the lower extremities in patients with CP. We reviewed the medical records of consecutive CP patients undergoing orthopedic surgery. Medical history, anesthesia emergence time, intraoperative body temperature, heart rate, blood pressure, immediate postoperative complications, Gross Motor Function Classification System (GMFCS) level, Cormack-Lehane classification, and American Society of Anesthesiologists physical status classification were analyzed. A total of 868 patients was included. Mean age at first surgery was 11.8 (7.6) yr. The incidences of intraoperative hypothermia, absolute hypotension, and absolute bradycardia were 26.2%, 4.4%, and 20.0%, respectively. Twenty (2.3%) patients had major complications, and 35 (4.0%) patients had minor complications postoperatively. The incidences of intraoperative hypothermia, absolute hypotension, and major postoperative complications were significantly higher in patients at GMFCS levels IV and V compared with patients at GMFCS levels I to III (P<0.001). History of pneumonia was associated with intraoperative absolute hypotension and major postoperative complications (P<0.001). These results revealed that GMFCS level, patient age, hip reconstructive surgery, and history of pneumonia are associated with adverse effects on intraoperative body temperature, the cardiovascular system, and immediate postoperative complications.

BACKGROUND: We evaluated the clinical and radiological results of one-stage correction for cerebral palsy patients. METHODS: We reviewed clinical outcomes and radiologic indices of 32 dysplastic hips in 23 children with cerebral palsy (13 males, 10 females; mean age, 8.6 years). Ten hips had dislocation, while 22 had subluxation. Preoperative Gross Motor Function Classification System (GMFCS) scores of the patients were as follows; level V (13 patients), level IV (9), and level III (1). Acetabular deficiency was anterior in 5 hips, superolateral in 7, posterior in 11 and mixed in 9, according to 3 dimensional computed tomography. The combined surgery included open reduction of the femoral head, release of contracted muscles, femoral shortening varus derotation osteotomy and the modified Dega osteotomy. Hip range of motion, GMFCS level, acetabular index, center-edge angle and migration percentage were measured before and after surgery. The mean follow-up period was 28.1 months. RESULTS: Hip abduction (median, 40degrees), sitting comfort and GMFCS level were improved after surgery, and pain was decreased. There were two cases of femoral head avascular necrosis, but no infection, nonunion, resubluxation or redislocation. All radiologic indices showed improvement after surgery. CONCLUSIONS: A single event multilevel surgery including soft tissue, pelvic and femoral side correction is effective in treating spastic dislocation of the hip in cerebral palsy.
