Spinal deformities following selective dorsal rhizotomy

Area of Science:

• Neurosurgery
• Pediatric Orthopedics
• Spinal Surgery

Background:

• Selective dorsal rhizotomy (SDR) offers significant benefits for children with spastic cerebral palsy (CP).
• Postoperative spinal deformities are a potential concern following SDR procedures.

Purpose of the Study:

• To evaluate the incidence and risk factors associated with postoperative spinal deformities in pediatric patients after SDR.

Main Methods:

• Retrospective review of 98 patients undergoing SDR (1991-2001).
• Analysis of preoperative and postoperative spinal radiographs.
• Regression analysis to identify predictors of spinal deformity.

Main Results:

• High rates of radiologically detected scoliosis (44.8%), hyperlordosis (19.5%), and spondylolisthesis (19.1%) were observed.
• Preoperative CP severity predicted scoliosis; less ambulatory patients were more prone.
• Younger age and male sex correlated with lower hyperlordosis rates.
• Spondylolisthesis occurred only in ambulatory children.

Conclusions:

• SDR in children with CP is associated with a high prevalence of asymptomatic spinal deformities.
• Factors such as ambulatory status, CP severity, age at surgery, and sex influence deformity development.
