摘要
目的观察双开门颈椎管成形合并羟基磷灰石人工骨材料植骨术治疗颈椎管狭窄症的效果。方法采用双开门法行颈椎管成形、椎管扩大及羟基磷灰石人工骨植骨术治疗12例颈椎管狭窄症。结果经过5年随访,11例发育性颈椎管狭窄患者临床症状明显缓解、体征改善,1例疗效不佳。结论双开门颈椎管成形及人工骨材料植骨术是治疗颈椎管狭窄症的一种安全有效的手术方法。羟基磷灰石载体具有良好的生物相容性及骨传导性,是理想的骨移植替代材料,在颈椎椎管成形术中具有良好的应用价值。
Objective To evaluate the effects of double-door laminoplasty and hydroxyapatite artificial bone grafting in the treatment of cervical spinal stenotic myelopathy. Methods Twelve cases of cervical spinal stenotic myelopathy underwent expansive double-door laminoplasty of the cervical spine and hydroxyapatite artificial bone grafting. The clinical outcome of the patients and the operative procedures were assessed. Results The 5-year follow-up showed significantly alleviated clinical symptoms and improved physical signs in all the patients except for 1 patient who responded poorly to the surgery. Conclusions Expansive double-door laminoplasty of the cervical spine in combination with hydroxyapatite artificial bone grafting is safe and effective for treating cervical spinal stenotic myelopathy. Hydroxyapatite artificial bone possesses good biological compatibility and osteoconduction, and is applicable in the laminoplasty procedures as an ideal bone graft material.
