Transpedicular balloon kyphoplasty for aged osteoporotic spinal compressive fractures / 中华骨科杂志

ABSTRACT

Objective To investigate the results of transpedicular balloon kyphoplasty for treatement of aged osteoporotic spinal compressive fractures. Methods Ten cases of aged osteoporotic spinal compressive fractures (range 57 to 72 years old), with T11 1 case, T12 4 cases, L1 5 cases were treated with kyphoplasties under “C” armed imaging guiding. The inflatable bone tamp was inserted into the fractured vertebral body transpedicularly in a minimally invasive way. The balloon was inflated, elevating the endplate and restoring vertebral body height and then confirmed by “C” armed imaging. The balloon was deflated and withdrawn, leaving a cavity within the vertebral body. The cavity was then filled with bone cement or other preferred material, creating an “internal cast” which was also confirmed by “C” armed imaging. Results The back pain disappeared immediately after the kyphoplasty in all of 10 cases. In the same day or following day after the procedure, the patients were allowed to get off bed. The height restoration of vertebral body and correction of kyphosis were confirmed by X-ray after the procedure. The average correction of kyphosis was 16?. At the time of the last follow up, all 10 cases retained the life style as before injury, there was no back pain, and deformity correction was maintained well. No complications occurred. Conclusion Kyphoplasty is a safe and effective way to treat aged osteoporotic spinal compressive fractures.
