摘　　要：单开门椎板成形术在多节段脊髓型颈椎病的治疗中得到广泛的应用,具有减压脊髓、缓解术前神经症状或体征、保持颈椎活动度的临床优势。然而,在临床工作中会经常遇到单开门椎板成形术后颈椎活动受限的患者,且在其术后颈椎正侧位X线片中能观察到相邻椎弓直接接触的现象,称之为相邻椎弓骨撞击,骨撞击是导致颈椎活动受限的重要原因之一。近年来有不少关于预防骨撞击术式改良的报道,虽然短期的临床效果显著,但长期的临床疗效有待进一步研究,同时对骨撞击的病因及发病机制尚无共识,本文就单开门椎板成形术后相邻椎弓骨撞击的流行病学、生物力学、临床表现、对手术疗效影响及其改良术式进行综述。Single-door laminoplasty has been widely used in the treatment of multisegment cervical myelopathy,with the clinical advantages of decompression of the spinal cord,relieving preoperative neurological symptoms or signs,and maintaining cervical mobility.However,in clinical work,patients with limited cervical spine activity after single open door laminoplasty are often encountered,and the direct contact with the adjacent vertebral arch can be observed in the postoperative X-ray of the anterior and lateral cervical spine,which is called the adjacent vertebral arch bone impact,which is one of the important causes of the limited cervical spine movement.In recent years,there have been many reports on the prevention of bone impact,although the short-term clinical effect is significant,but long-term clinical efficacy to be further study,and the cause and the pathogenesis of bone impact is no consensus,this paper on the surgery of adjacent vertebral arch impact epidemiology,biomechanics,clinical performance,surgical effect and improvement.
