Cervical degenerative pathology can produce pain and disability and, in case of failure of conservative treatment surgery is indicated.
107 patients affected by single level cervical degenerative pathology were surgically treated by Cloward procedure. On radiographs, the sagittal segmental alignment (SSA) of the affected level and sagittal alignment of the cervical spine were measured.
Preoperatively, mean SSA was 0.6° and at the last follow-up 1.8°. In particular, adjacent-level degeneration occurred more frequently in Group A than in Group B.
Lordotic SSA angle can be considered a protective factor against adjacent-level degeneration.
颈椎退行性病变可引起疼痛和残疾,在保守治疗失败的情况下,手术是指征。
107 例单节段颈椎退行性病变患者接受 Cloward 手术治疗。在影像学上,测量病变节段的矢状位节段排列(SSA)和颈椎的矢状位排列。
术前 SSA 平均为 0.6°,末次随访时为 1.8°。特别是 A 组比 B 组更容易发生相邻节段退变。
前凸 SSA 角可被视为预防相邻节段退变的保护因素。
