摘要

Objective

Neuromuscular scoliosis (NMS) typically develops at an early age, leading to postural instability and cardiopulmonary complications due to spinal deformity and pelvic obliquity. Long-term comfort requires surgical intervention to restore spino-pelvic balance. This study aimed to report the long-term outcomes of a reverse T-construct pelvic fixation technique combined with magnetically controlled growing rods for the pediatric NMS treatment.

Methods

Between 2016 and 2023, 34 patients with NMS underwent surgery using the reverse T-construct using two sacral screws and two iliac screws connected by a horizontal rod, linked to magnetically controlled growing rods. Clinical and radiographic outcomes were evaluated with a minimum follow-up of two years.

Results

The mean age at surgery was 10 ± 1.7 years. The mean preoperative Cobb angle of 69.9° ± 20.3, was decreased to 35.6° ± 21.4 postoperatively. At the last follow-up, the average correction loss was 8.9° ± 17 (p < 0.05). The mean preoperative pelvic obliquity of 14.8° ± 11.1, improved to 3.3° ± 3.7 postoperatively, with an average correction loss of 1.5° ± 3.5° at the last follow-up (p < 0.05). Two postoperative infections and two cutaneous complications were reported. Eight mechanical complications were recorded: one rod fracture, one migration of a rib hook, and six related to pelvic fixation.

Conclusions

The reverse T-construct with magnetically controlled growing rods demonstrated satisfying long-term correction of spinal alignment and pelvic obliquity. This technique offers stable pelvic balance, early mobilization, with a low complication rate, making it a viable alternative for managing patients NMS.
