Abstract:

BACKGROUND: At present, lumbar fusion, which is widely used in the treatment of lumbar degenerative diseases, usually leads to lumbar stiffness and acceleration of adjacent segment degeneration. Non fusion, such as total disc replacement, is an effective way to avoid these problems, but there are some disputes about the value and indications.

OBJECTIVE: To evaluate the efficacy and safety of total disc replacement in the treatment of lumbar degenerative diseases.
METHODS: Totally 97 cases of degenerative diseases of the lumbar spine were treated by surgical treatment, and they were divided into 2 groups according to the operation methods. 55 cases underwent lumbar fusion surgery in the fusion group and 42 cases underwent artificial total disc replacement in the replacement group. All patients were followed up for 6 years. The Visual Analogue Scale (VAS) score, Oswestry Dysfunction Index (ODI), and the incidence of complication were compared between the two groups before and after the operation.
RESULTS AND CONCLUSION: (1) There were no significant differences in general information, VAS score, and ODI between the two groups before operation (P > 0.05). (2) The operation time and postoperative hospital stay in the replacement group were significantly shorter than that in the fusion group, and the amount of bleeding during operation was significantly lower in the replacement group than that in the fusion group (P < 0.01). (3) The scores of VAS and ODI in two groups were significantly lower after operation than those before operation (P < 0.01). The VAS score and ODI in the replacement group were significantly lower than that in the fusion group at postoperative 6 months and 1 year after operation (P < 0.01). (4) The incidence of complications in the replacement group (2%) was significantly lower than that in the fusion group (5%) (P < 0.05). (5) In conclusion, artificial total disc replacement for the treatment of degenerative lumbar disease can effectively relieve the pain of lumbago and leg, improve the lumbar function and have better medium-term and long-term effects.
