Abstract
Objective: This study evaluates the use of the Isola Growing Rod System for scoliosis in a group of skeletally immature patients with predominantly neuromuscular disorders. Our series of patients was unsuitable for definitive anterior and posterior fusion due to poor respiratory function.
Design: We reviewed the case notes and x-rays of eighteen patients who had undergone instrumentation with the Isola Growing Rod System. The Cobb angles on the pre-operative and subsequent post-operative X-rays were measured. Complications were noted.
Subjects: Eighteen children with scoliosis.
Outcome measures: Curve correction and complications.
Results: Two patients had idiopathic scoliosis, four patients had spinal muscular atrophy with the remainder having varied diagnoses. Eight patients were fully ambulant, the remainder being wheelchair bound pre-operatively. The average age at rod insertion was eight years, three months. The average number of lengthenings was four. The mean pre-operative Cobb angle was 76 degrees, the mean most recent Cobb angle 28 degrees. One patient required definitive fusion. Two patients required revision procedures due to implant failure.
Conclusion: Our study shows that progressive scoliosis associated with neuromuscular disorder can be controlled with the growing rod system, thus avoiding both anterior release and the ‘crankshaft’ phenomenon, until the optimal time for definitive spinal fusion.
