No firm statistical evidence exists establishing the superiority of the anterior or the posterior approach in the management of spondylostenosis, although some sense of order is evolving. In general the consensus suggests that in spondylostenosis, the anterior approach may be preferred for disc or segmental osteophyte intrusions limited to one or two levels. Laminectomy is the preferred procedure in patients with a narrowed canal and multiple level involvement. The surgeon's personal preference and experience remains the dominant factor. Patients with congenital stenosis involving all of the major segments, with or without superimposed developmental changes, require more extensive laminar decompression with proper attention to the craniocervical junction where anomalies may occur. The success of laminectomy is dictated by the preservation of cervical lordosis. In patients with major dorsally located abnormalities such as hyperlordosis, shingling, and arthrosis with hypertrophy of the yellow ligaments, posterior decompression is essential. Subsequent stabilization is rarely required with proper surgical and postoperative care. Both an anterior and posterior approach may be indicated in unique circumstances of spondylostenosis complicated by subluxation and instability.
虽然目前尚无确凿的统计学证据证实前路或后路手术在治疗脊椎狭窄症方面的优越性,但已逐渐形成了一些共识。一般来说,对于局限于一两个节段的椎间盘或节段性骨赘侵入,前路手术可能更受青睐。对于椎管狭窄且累及多个节段的患者,椎板切除术是首选的手术方式。外科医生的个人偏好和经验仍是主要因素。对于累及所有主要节段的先天性狭窄患者,无论是否伴有叠加的发育性改变,都需要进行更广泛的椎板减压,并适当关注可能出现异常的颅颈交界区。椎板切除术的成功取决于对颈椎生理前凸的保留。对于存在严重的背部异常情况(如颈椎前凸过大、椎板重叠、关节病伴黄韧带肥厚)的患者,后路减压至关重要。在适当的手术和术后护理下,很少需要进行后续的稳定手术。在脊椎狭窄症合并半脱位和不稳定的特殊情况下,可能需要同时采用前路和后路手术。
