A case study of an 18-month-old female with craniovertebral instability and spinal cord compression requiring circumferential stabilization. A review of surgical techniques in upper cervical spine and craniovertebral stabilization for young children is provided.
To describe an interesting surgical approach in a young pediatric patient requiring circumferential stability at the craniovertebral junction.
Craniovertebral instability is problematic in the young pediatric population due to the inability to secure hardware for stabilization. We present an interesting case of spinal cord compression with craniovertebral instability in an 18-month-old female requiring circumferential cervical spine and craniovertebral stabilization.
The patient presented with acute onset quadriparesis after a fall. Radiographs demonstrated C2-C3 disruption with canal compromise. Magnetic resonance imaging revealed signal changes of the spinal cord at C2-C3. Neurological examination revealed normal muscle volume with strength 1/5 in the upper extremities and 0/5 in the lower extremities. Respirations were normal with normal diaphragmatic function. Cranial nerves were intact.
Halo-traction attempted at 0.453 kg induced occipital-atlantal dislocation. The patient underwent anterior corpectomy of C3 and the base of C2 with autologous rib grafts placed from C2 to C4 and macropore as an anterior plating system. Posteriorly the patient had occiput-C3 fusion with a titanium rod and autologous rib grafts bilaterally. Postoperatively the patient regained normal neurological function with circumferential fusion after 4 months in a halo vest.
This case demonstrates the ability to achieve circumferential stabilization in the young pediatric patient. Injuries at the odontoid synchondrosis can be difficult to treat and are only complicated by having to achieve a posterior fusion at the craniovertebral junction. We present a successful case of circumferential fusion and offer a surgical technique to achieve spinal cord decompression and fusion of the upper cervical spine and craniovertebral junction in the young pediatric population.
一项针对一名18个月大患有颅颈不稳定和脊髓受压且需要进行环形稳定术的女性患者的病例研究。本文还对上颈椎及幼儿颅颈稳定术的手术技术进行了综述。
描述一种针对一名需要在颅颈交界处进行环形稳定术的小儿患者的有趣手术方法。
由于无法固定用于稳定的硬件装置,颅颈不稳定在小儿人群中是个难题。我们报告了一例18个月大患有颅颈不稳定和脊髓受压的女性患者,该患者需要进行颈椎和颅颈交界处的环形稳定术。
该患者在跌倒后出现急性四肢瘫。X线片显示C2 - C3节段脱位并伴有椎管狭窄。磁共振成像显示C2 - C3节段脊髓信号改变。神经学检查显示肌肉量正常,上肢肌力为1/5,下肢肌力为0/5。呼吸正常,膈肌功能正常。颅神经完整。
尝试以0.453千克进行头环牵引导致枕寰关节脱位。患者接受了C3椎体及C2椎体基部的前路椎体次全切除术,取自体肋骨植骨并从C2至C4使用大孔前路钢板系统。后路进行枕骨 - C3融合术,双侧使用钛棒和自体肋骨植骨。术后,患者在佩戴头环背心4个月后实现环形融合,神经功能恢复正常。
本病例证明了在小儿患者中实现环形稳定的能力。齿突软骨结合处损伤可能难以治疗,且因必须在颅颈交界处进行后路融合而更加复杂。我们展示了一例成功的环形融合病例,并提供了一种手术技术,以实现小儿人群中上颈椎和颅颈交界处的脊髓减压和融合。
