ABSTRACT
PURPOSE:
To study clinical and radiological outcomes of pediatric cervical kyphosis correction with a standalone posterior cervical approach. Cervical spine kyphotic deformity in pediatric age group is a distinct entity and the management is challenging. Pediatric cervical kyphosis is less often encountered, and literature is sparse with only few case series. Management algorithms are devised keeping the flexibility of the deformity at the core of decision making. Circumferential fusion is mostly recommended for non-flexible (rigid) kyphosis.METHODS:
Authors present a single center retrospective analysis of cases of pediatric cervical kyphosis managed by a standalone posterior approach. Pre- and post-operative clinical and radiological parameters were recorded and analyzed. Changes in neurological status, kyphosis correction and bony fusion were assessed. Surgical and implant related complications were noted.RESULTS:
Seven cases (6 male, 1 female) were included. Mean age was 13.9±2.9 years, ranging from 8-17 years. Etiology was traumatic in 2 cases, developmental in 2, and syndromic, Hirayama disease and post-laminectomy in 1 case each. Mean kyphosis correction was 36.80±19.30 (87%±21%) with a mean pre-operative kyphosis angle of 37.80±15.30 and mean immediate post-operative kyphosis angle of 3.70±8.70. Mean hospital stay duration was 10±6 days. Median follow-up duration was 36 months. Myelopathy improved in 5 cases at last follow-up. Six cases demonstrated bony fusion at a mean follow-up of 8.4±1.5 months.CONCLUSION:
Significant immediate correction in pediatric cervical kyphosis may be achieved with a standalone posterior approach with proper planning and technique in selected cases. Inserting pedicle screws at strategic locations of implant construct offer better corrections and pull-out strength and maintain long-term stability resulting in higher arthrodesis rates. Larger studies with longer follow up are needed to further ascertain the role of standalone posterior cervical approaches in pediatric cervical kyphosis.
