Abstract:
Objective: To compare the effectiveness of short-segment and long-segment bone cement-augmented fixation combined with vertebroplasty in treatment of stage Ⅲ Kümmell disease. Methods: A clinical data of 44 patients with stage Ⅲ Kümmell disease met the selection criteria between January 2014 and December 2017 was retrospectively analyzed. Eighteen cases were treated with short-segment bone cement-augmented fixation combined with vertebroplasty (short-segment group) and 26 cases were treated with long-segment bone cement-augmented fixation combined with vertebroplasty (long-segment group). There was no significant difference in gender, age, disease duration, fracture segment, bone mineral density (T value), Frankle grading, and preoperative pain visual analogue scale (VAS) score, Oswestry disability index (ODI), anterior edge height of injured vertebrae, kyphosis Cobb angle, and thoracolumbar kyphosis (TLK) between the two groups ( P>0.05). The operation time, intraoperative blood loss, bone cement injection volume, bone cement leakage rate, VAS score, ODI, anterior edge height of injured vertebrae, kyphosis Cobb angle, and TLK were compared between the two groups. Results: The operation time and the intraoperative blood loss in the short- segment group were significant lower than those in the long-segment group ( P<0.05). There was no significant difference in bone cement injection volume and bone cement leakage rate between the two groups ( P>0.05). All patients were followed up 12-36 months, with an average of 24.4 months. The VAS score, ODI, anterior edge height of injured vertebrae, kyphosis Cobb angle, and TLK significantly improved at 1 week after operation and last follow-up in the two groups ( P<0.05), there was no significant difference between the two groups ( P>0.05). At last follow-up, the neurological function of the two groups recovered, and there was no significant difference in Frankle grading between the two groups ( P>0.05). There were 3 cases (16.67%) of non-surgical vertebral fractures in the short-segment group and 6 cases (23.08%) in the long-segment group, showing no significant difference between the two groups ( P>0.05). Bone rejection occurred in 1 case in the short-segment group, and neither internal fixation failure nor collapse of the injured vertebrae occurred during follow-up. Conclusion: Both short-segment and long-segment bone cement-augmented fixation combined with vertebroplasty can achieve good effectiveness in treatment of stage Ⅲ Kümmell disease, and can maintain the height of the injured vertebra and prevent the collapse of the injured vertebra. Compared with long-segment fixation, short-segment fixation has the advantages of shorter operation time and less intraoperative bleeding.
