Factors Thoracolumbar Osteoporotic Compression Fractures In Patients With Postoperative Pain Improvement PVP Analysis

Purpose：Explore osteoporotic compression fractures related factors in patientswith percutaneous vertebroplasty (PVP) pain improvement after treat.Methods: A retrospective analysis of240patients with vertebroplasty (PVP)treatment of osteoporotic thoracolumbar compression fracture cases. All patients will bedivided into four groups, each group60cases. A vertebral compression group study groupswere divided into two portions A1and A2, A1case of vertebral compression ratio less than35%, between35%-50%of cases of vertebral compression A2. Group B cobb angle studygroup is divided into two parts, B1and B2, B1cases of kyphosis cobb angle is less than15°, B2cases cobb angle between15°-25°. Group C bone density study group, alwaysmake divided into two parts, C1and C2. C1part of the bone mineral density T-scorebetween-1and-2.5, C2part of bone mineral density T-score less than-2.5. Group D is theamount of bone cement injected into the study group between2ml-4ml, between D1D2partial amount of bone cement injected into the part of the bone cement injection volume4ml-6ml. Preoperative routine X-ray, CT and MRI, postoperative follow-up observationand periodic review. Each of the two groups were recorded and compared VAS pain scoreimprovement.Results: The analysis and comparison of A, B, C, D four factors research group,rational grouping, four factors have impact on the VAS scores of different time periods, thedifference was statistically significant (P <0.05). Each grouping internal factors, differentfor different time periods VAS scores were significantly affect the difference wasstatistically significant (P <0.01), vertebral compression ratio group, kyphosis Cobb’s anglegroup and BMD measurements of bone cement injected group difference in the amount of internal group at different times of the VAS scores had no significant effect, the differencewas not statistically significant (P>0.05)Conclusions:(1) Percutaneous vertebroplasty (PVP) treatment of thoracolumbarosteoporotic compression fracture effect is significant and effective. It can effectively andquickly relieve pain and restore vertebral body strength and stiffness, and can improve theinjured vertebral height, increase the stability of the spine biomechanics, satisfactoryfollow-up of efficacy.(2) preoperative kyphosis vertebral compression rate and the size ofcobb’s angle or not, no significant difference in improving postoperative pain in patientswith PVP, that pain can be significantly alleviated. But the greater the preoperativevertebral compression ratio, the more obvious postoperative vertebral height restoration.(3)The lower bone mineral density, the greater the degree of dispersion after the injection ofbone cement, improving patient pain, the more obvious that the more satisfactory.(4) theamount of bone cement injected to improve postoperative pain and no significantcorrelation. But PVP intraoperative injection of bone cement should not be too large,especially for patients with more severe osteoporosis, to reduce the likelihood of theoccurrence of bone cement leakage and reduce long-term risk of adjacent vertebralfractures.
