Posterior-only unit rod instrumentation and fusion for neuromuscular scoliosis.

摘要: Study Design. A retrospective study to determine the efficacy of posterior-only unit rod instrumentation and fusion in a skeletally immature neurornuscular scoliosis population. Objective. To whether approach this population adequately addresses concerns correction pelvic obliquity, maintenance that over time, inci dence crankshaft phenomenon. Summary Background Data. Controversy exists regarding need for anterior release improve curve flexibility obtain an arthrodesis those petients at risk crankshafting with continued growth Methods. From 1992 through 1997, 28 consecutive patients neuromuscular underwent treatment progressive, symptomatic spinal deformities. Preoperative, immediate postopera tive, final follow-up radiographs were analyzed respect obliquity correction, development phenomenon as evidenced by loss and/or increased rib-vertebral angle difference. The average age was 12.8 years 58 months minimum 2 years. Results. Twenty-six available follow-up. initial Cobb averaged 66%, 75% corrected. These corrections maintained time. Before surgery 27 Risser 0, 1, or 2. triradiate cartilage open nine patients, five ≥ 10 age. At 22 26 5 4 4. There one patient difference length follow-up, no frontal sagittal plane atignment. Conclusions results indicate even very young patient, acceptable amounts can be achieved fusion. biomechanical stiffness construct seemed able prevent majority risk.
