Abstract:
[Objective]To discuss the pathological typing of posterior longitudinal ligament(PLL) in cervical spondylotic myelopathy.[Method]Data of pathological typing and resection methods of PLL were reviewed in 87 patients with cervical spondylotic myelopathy.[Result]The degeneration of the posterior longitudinal ligament(DPLL) was divided into single-DPLL(n=34,39.1%) and proliferation-DPLL(n=53,60.9%) by the results of resecton and pathological studies.The proliferation-DPLL was subdivided into hyperplasy-DPLL(n=26,29.9%),accretion-DPLL(n=12,13.8%)and ossification-DPLL(n=15,17.2%).[Conclusion]The posterior longitudinal ligament can thoroughly be resected in cervical spondylotic myelopathy combined with single-DPLL or with hyperplasy-DPLL.In cervical spondylotic myelopathy combined with accretion-DPLL or ossification-DPLL,complete decompression can be obtained by isolating the accretion and the ossification-chondrification of DPLL.
