Transpedicular Kyphoplasty For Middle Thoracic Osteoporotic Vertebral Compression Fractures With Limited Incision

Objective To evaluate the clinical feasibility, curative effectiveness of middle thoracic osteoporotic vertebral compression fractures using transpedicular kyphoplasty with limited incision.Methods From December 2015 to September 2013,36 patients with middle thoracic osteoporotic vertebral compression fractures in our hospital were allocated to two groups randomly and equally. The test group were used transpedicular kyphoplasty with limited incision (n=18), and the control group were used percutaneous kyphoplasty surgery (n=18). Of them, there were 7 males and 29 females with an average age of 74.5 years old (ranged from 64 to 86). The fracture involved 42 vertebral bodies (7 segments of the T5,8 segments of T6,15 segments of T7 and 12 segments of T8). Single vertebral fractures in 30 cases and double-vertebral fractures in 6 cases. All patients were followed up more than 6 months after operation. By comparing and analyzing visual analogue scale (VAS), Oswestry disability index (ODI) scores, Cobb angle function of kyphosis, the operation time,hospital stay, intraoperative blood loss, X-ray fluoroscopy times and the bone cement leakage at 1 day pre-opratively,1 day post-operatively,3 months post-operatively and 6 months post-operatively between two groups.Results The VAS scores, ODI scores and Cobb angle function of kyphosis were lower at each time point post-operatively than 1 day pre-opratively in both groups (P<0.05). The test group showed obviously lower levels of the operation time and X-ray fluoroscopy times than that of the control group, and significantly higher levels of intraoperative blood loss than that of the control group (P<0.05). The test group had similar rates of the bone cement leakage to routine group (P>0.05). There were no meaning in VAS scores, ODI scores, hospital stay and Cobb angle function of kyphosis at 1 day pre-opratively and each time point post-operatively between two groups (P>0.05).Conclusion 1.Transpedicular kyphoplasty for middle thoracic osteoporo-tic vertebral compression fractures with limited incision has advantages of less radiation damage and shorter operation.2.Transpedicular kyphoplasty for middle thoracic osteoporotic vertebral compression fractures with limited incision needs less equipment requirements, which is suitable for use in the promotion of primary hospital.3.Compared with classic PKP, transpedicular kyphoplasty with limited incision has similar clinical curative effectiveness.
