Abstract:
OBJECTIVE:By comparing the clinical efficacy of short-segment and long-segment fixation for single-segment thoracic and lumbar spine III stage Kümmell disease to explore a more suitable fixed segment for the disease.
METHODS:The clinical data of 46 patients with single-segment thoracic and lumbar spine III stage Kümmell disease treated from July 2013 to December 2016 were retrospectively analyzed. Forty-six patients were divided into short-segment fixation group(one vertebra above and below the diseased vertebra) and long-segment fixation group(two vertebrae on the upper and lower of the diseased vertebra) according to different methods of cement stick fixation. There were 25 patients in the short-segment fixation group, including 9 males and 16 females, with an average age of (75.3±4.5) years old, lumbar spine bone mineral density T-value of (-3.1±0.3) g/cm³, follow-up time of (13.0±2.3) months; there were 21 patients in long-segment fixation group, 6 males and 15 females, with an average age of (74.5±3.9) years old, lumbar spine bone mineral density T-value of (-3.2±0.3) g/cm³, follow-up time of (14.7±3.6) months.The gender, age, follow-up time, operation time, intraoperative blood loss, cement leakage, and the rate of adjacent vertebrae fractures were compared between two groups, as well as pain VAS score, ODI, and kyphosis angle before and after surgery.
RESULTS:There were no significant differences in age, gender, bone density, pain VAS score, ODI, and kyphosis between two groups before surgery. The operation time and intraoperative blood loss of short-segment fixation group were less than that of long-segment fixation group. The pain VAS score, ODI and kyphosis of the two groups were significantly improved at 7 days after the operation and at the latest follow-up, there was no significant difference between two groups. There were no significant differences in bone cement leakage(9/25 vs 11/21) and adjacent vertebrae fractures(4/25 vs 3/21).
CONCLUSIONS:Both long-segment fixation and short-segment fixation can effectively relieve pain, correct kyphosis, improve functional index, and achieve better clinical results, but short-segment fixation has less operation time and less intraoperative blood. So single-segment thoracic and lumbar spine III stage Kümmell disease does not need to extend the fixed segment, short-segment fixation is more in line with clinical needs and worthy of further study.
