Cervical disc replacement and anterior interbody fusion in the repair of middle-aged patients with cervical spondylosis:cervical function and range of motion / 中国组织工程研究

ABSTRACT

BACKGROUND:The development of spinal non-fusion technology promoted movement function protection of adjacent segment and operating segment. In the treatment of cervical spondylosis surgery, non-fusion technology has been widely carried out. For middle-aged patients with cervical spondylosis, the demand for spinal joint movement function is high. Non-fusion technology can improve the postoperative quality of life and slow down the risk of adjacent segment degeneration. OBJECTIVE:To evaluate the clinical efficacy of anterior cervical different implant materials (fusion or non-fusion) in the treatment of single segment of the intervertebral disc degeneration of cervical spondylosis in middle-aged patients. METHODS:This study enrol ed 10 cases of single segmental radiculopathy and cervical myelopathy after cervical intervertebral disc replacement from June 2011 to June 2013. Simultaneously, 10 cases were randomly selected from patients with anterior interbody fusion as the control group. Before treatment, at 1 and 3 months, and 1 year after treatment, changes in range of motion of cervical vertebra were observed using imaging results. Therapeutic effects were assessed using Japanese Orthopaedic Association Scores, Visual Analog Scale and The Neek Disability Index in both groups. RESULTS AND CONCLUSION:Al patients did not suffer from incision fat liquefaction, infection and delayed healing, and had finished fol ow-up for more than 1 year. Results revealed that Japanese Orthopaedic Association Scores and Visual Analog Scale scores were improved at 1 and 3 months, and 1 year after treatment (P0.05). In the analysis of range of motion of cervical vertebra and The Neek Disability Index, there were significant advantages in non-fusion treatment group (P<0.05). For middle-aged patients with cervical spondylosis, due to its life demand for neck mobility, the repair program of non-fusion cervical intervertebral disc replacement has a clear advantage.
