Manual reduction combined with percutaneous vertebroplasty for the treatment of osteoporotic vertebral compression fractures with intravertebral clefts / 中国骨伤

ABSTRACT

OBJECTIVE@#To explore the therapeutic efficacy of manual reduction combined with percutaneous vertebroplasty in treating osteoporotic vertebral compression fractures(OVCFs) with intravertebral clefts.@*METHODS@#The clinical data of 94 patients with osteoporotic vertebral compression fractures with intravertebral clefts treated from January 2014 to January 2017 were retrospectively analyzed. The patients were divided into group A and group B according to different operative methods. In group A, 45 patients were treated with unilateral approach PVP, including 17 males and 28 females, aged (75.35±11.82) years old, with a bone density T-value of (-4.28±0.65) g/cm³; in group B, 49 patients treated with manual reduction combined with unilateral approach PVP, including 19 males and 30 females, aged (76.79±9.64) years old, with a bone density T-value of (-4.33±0.72) g/cm³. The operation time, bone cement injection volume and postoperative complications of two groups were recorded. The VAS and ODI scores of two groups were analyzed respectively at 1, 12, 18 months after operation. Vertebral height and kyphosis Cobb angle of two groups were compared immediately after surgery and 12, 18 months after operation. The distribution of bone cement in the vertebral body was observed and its distribution excellent rate was calculated.@*RESULTS@#There was no significant difference in operation time between two groups. The amount of bone cement injection was(8.42±1.24) ml in group A and(9.19±1.09) ml in group B, and the difference between two groups was statistically significant(0.05), but group A was higher than group B at 12 and 18 months after operation (<0.05). The vertebral height and Cobb angle before surgery, immediately after surgery, and 12, 18 months after surgery in group A were(59.17±1.42)%, (85.95±2.19)%, (75.27±3.45)%, (68.34±2.24)% and(23.83±3.37)°, (15.26±2.61)°, (17.63±2.16)°, (19.46±2.54)°, and in group B were(59.31±1.87)%, (89.19±2.53)%, (88.62±2.51)%, (88.59±2.62)% and(24.72±3.78)°, (14.91±2.28)°, (15.48±2.55)°, (15.86±2.81)°. Vertebral height Immediately after surgery was greater in group B than in group A and Cobb angle in group B was smaller than in group A (<0.05). During follow-up, there was no significant change in vertebral height in group B, while vertebral body recollapse in group A(<0.05).@*CONCLUSIONS@#In the treatment of osteoporotic vertebral compression fractures with intravertebral clefts, the manual reduction combined with PVP is more effective than single PVP, which can effectively prevent vertebral body recollapse and improve the long-term efficacy of patients.
