ABSTRACT
STUDY DESIGN:
Retrospective analysis.OBJECTIVE:
To evaluate, in children with cerebral palsy, the following aspects of growing rod (GR) treatment for scoliosis structural effectiveness, effect of pelvic fixation, hospital stay duration, and complications. SUMMARY OF BACKGROUND DATA Children with cerebral palsy frequently develop severe spinal deformity and pelvic obliquity (PO). Growth-preserving strategies are attractive, but comorbidities raise the risk/benefit ratio. To our knowledge, no previous studies have focused on growth-preserving spine surgery in these children.METHODS:
From our multicenter patient group, we identified 27 children with cerebral palsy treated with GRs (single rod in 4; dual rods in 23 [15 extending to the pelvis]). We collected radiographical, surgical, hospital stay, and major complication data. We compared Cobb angle and PO improvement between patients with and without pelvic instrumentation via the Student t test (significance, P = 0.05). No patient required anterior spinal fusion.RESULTS:
Average improvements for all patients (preoperative to latest follow-up) were Cobb angle, 35° ± 23°; PO, 14° ± 19°; T1-S1 length, 7.9 ± 4.4 cm; and space available for lung ratio, 0.17 ± 0.21. For the 8 patients who underwent fusion, average improvements (preoperative to postfusion) were Cobb angle, 43° ± 28°; PO, 2° ± 21°; T1-S1 length, 9.5 ± 6.0 cm; and space available for lung ratio, 0.26 ± 0.28. Pelvic GR fixation produced better PO correction (P < 0.001) but similar Cobb angle correction (P = 0.556). Hospital stays averaged 8.7 ± 12.1 days after initial surgery, 1.4 ± 2.5 days after lengthening (45% were outpatient procedures), and 13.4 ± 6.2 days after fusion. The most common complication was deep wound infection (30%).CONCLUSION:
GRs via a posterior-only approach are effective. Constructs extending to the pelvis control PO more effectively. However, 30% of patients experienced deep wound infection.
