Effects of Bilateral Transpedicular Kyphoplasty with Single Balloon on the Treatment of Osteoporotic Vertebral Compressed Fractures for Elder Patients

Objective: To investigate the clinical efficacy of bilateral transpedicular kyphoplasty with single balloon on the treatment of the osteoporotic vertebral compressed fractures in elder patients. Methods: 52 patients with osteoporotic vertebral compressed fractures who were treated by the percutaneous bilateral transpedicular kyphoplasty with single balloon were selected. Then the VAS of patients, the vertebral height restoration, the improvement of Cobb's angle after the operation and the postoperative recurrence of patients were analyzed. Results: All the patients were followed up for 2-17 months and experienced dramatic pain relief after the procedures. The average pain score(VAS) of patients decreased from 8.6 to 2.5 after the operation, and there was statistically significant difference(P0. 05). The vertebral height restoration on the anterior border was(56.5%±34%), the middle portion was(60.5%±35.4%), and the posterior border was(40.7%±32.3%). The improvement of sagittal alignment was significant(P0.05). Comparing with the situation before operation, the average correction of Cobb's angle has reached 10° presented by the X-ray(P0.05). There were three cases with no more clinical symptoms but less cement at the anterior vertebral edge after treatment. Another one with intercostal neuralgia got relief when treated by NSAIDs for six months. Conclusion: It is obvious that the bilateral transpedicular kyphoplasty with single balloon has the influence on the treatment of osteoporotic vertebral compressed fractures, and it is worthy of clinical promotion.
