Abstract:

BACKGROUND: With the mature of the spinal surgery and the development of fixation instrument, spine fusion and fixation has become the main method for the treatment of spine diseases, but the long-term adjacent segment degeneration is more and more serious.
OBJECTIVE: To retrospectively analyze the risk factors of adjacent segment degeneration after spinal fixation, which can help to improve spine fixation and reduce the long-term complications.
METHODS: A computer-based search was performed on VIP database and PubMed database for the articles on the adjacent segment degeneration after spine fusion and fixation published from January 2005 to December 2012, the key words were “spine fusion, adjacent segment degeneration, unilateral single cage” in Chinese and English. All articles were selected firstly, and those related to adjacent segment degeneration after spine fusion were collected. Randomized controlled trials were included and the nonrandomized controlled trials were excluded. The duplicated investigations were eliminated. The articles explored the adjacent segment degeneration after spine fusion mainly dependent on the surgical method, fusion mode and damage of adjacent segment.
RESULTS AND CONCLUSION: A total of 27 articles were coincident with the inclusion criteria. From the articles, we find that the fusion number, way, position and the damage to the adjacent segment were the main reasons for adjacent segment degeneration. The total disc replacement and unilateral single cage play important role in preventing and delaying the adjacent segment degeneration. The influence of the fixation materials and surgical way should be considered before fusion, in order to avoid and reduce the occurrence of adjacent segment degeneration.
