The authors report the novel use of sublaminar polyester bands in posterior instrumented spinal fusions of the thoracic and lumbar spine and sacrum in 5 children. This is the first reported use of polyester bands in spinal surgery in the United States.
The authors retrospectively reviewed the demographics and procedural data for children who underwent posterior instrumented fusion using sublaminar polyester bands.
Five children, ranging in age from 9 months to 18 years, underwent posterior instrumented fusion for posttrauma kyphotic deformity (1 patient), congenital scoliosis from hemivertebra anomaly (3 patients), and neuromuscular scoliosis associated with spina bifida (1 patient). There were 1 instance of lamina fracture with application and tensioning of the polyester band and 1 instance of transient worsening of proprioception with sublaminar passage of the polyester band.
Pedicle screws, laminar/pedicle/transverse process hooks, and sublaminar metal wires have been incorporated into posterior spinal constructs and widely reported and used in the thoracic and lumbar spine and sacrum with varying success. This report demonstrates the successful results of hybrid posterior spinal constructs that include sublaminar polyester bands that promise the technical ease of passing sublaminar instrumentation with the immediate biomechanical rigidity of pedicle screws and hooks.
作者报告了在 5 例儿童胸椎、腰椎和骶骨后路器械融合中使用聚酯带的新方法。这是聚酯带在美国首次应用于脊柱手术的报道。
作者回顾性分析了使用聚酯带行后路器械融合的儿童患者的人口统计学和手术资料。
5 例儿童（年龄 9 个月至 18 岁）因创伤后后凸畸形（1 例）、半椎体畸形所致先天性脊柱侧凸（3 例）和脊膜膨出相关神经肌肉性脊柱侧凸（1 例）接受了后路器械融合。1 例在应用和拉紧聚酯带时出现椎板骨折，1 例在聚酯带经椎板下通过时出现短暂的本体感觉恶化。
椎弓根螺钉、椎板/椎弓根/横突钩和经椎板金属丝已被纳入后路脊柱结构中，并在胸椎、腰椎和骶骨中得到广泛报道和应用，取得了不同的效果。本报告展示了包括聚酯带的混合后路脊柱结构的成功结果，这种结构具有经椎板器械置入的技术优势，同时具有椎弓根螺钉和钩即刻生物力学刚性。
