The percutaneous kyphoplasty treatment of osteoporosis thoracolumbar vertebral compression fractures

Objective To evaluate the clinical efficacy of percutaneous kyphoplasty( PKP) in treating refractoy low back pain in patients with osteoporotic thoracolumbar vertebral compression fractures. Methods PKP was used to treat 59 cases of osteoporotic vertebral compression fracture patients( 80 vetebrae). VAS scores,vertebral height and Cobb angle changes recorded before and after surgery were compared in order to analyse the effect. Results PKP was successfully performed on these patients,and there was no neurological impairment or bone cement allergy in these patients. The 59 cases were successfully followed up for 24 months. VAS values were respectively 6. 06 ± 1. 02 points before operation,2. 45 ± 1. 04 points after the operation,2. 80 ± 1. 13 points in 12 months after surgery and 2. 90 ±1. 90 points in 24 months after surgery,the kyphosis Cobb angles were respectively 24. 62° ± 4. 71°,21. 71° ± 3. 92°,22. 20° ± 3. 60°,22. 90° ± 3. 28°,vertebral height value were respectively 19. 0 mm ± 1. 80 mm,26. 3 mm ± 2. 10mm,25. 9 mm ± 2. 00 mm,24. 2 mm ± 2. 03 mm. All the differences were statistically significant( P 0. 05). The treatment efficiency rates were respectively 93. 00% after surgery,81. 72% in 12 months and 72. 09% in 24 months.Conclusions PKP is effective for osteoporotic thoracolumbar vertebral compression fractures,which has minimal trauma and good security. It can rapidly relieve pain,obtain a satisfactory clinical result.
