Randomized Controlled Trial Comparative Study
A comparison between unilateral transverse process-pedicle and bilateral puncture techniques in percutaneous kyphoplasty.
A prospective comparative study. ⋯ Both bilateral and unilateral PKP are relatively safe and provide effective treatment for patients with painful osteoporotic vertebral compression fracture. However, unilateral PKP received less radiation dose and operation time, it also offered a higher degree of deformity correction and resulted in less complication than bilateral PKP.

A retrospective and radiological study of degenerative spinal diseases. ⋯ In degenerative spinal diseases, long instrumentation and fusion (≥ 2 levels) provides more efficient LL reconstruction. PT, SS, and SVA improve corresponding to LL in a linear regression model. Linear regression equations could be developed and used to predict PT and SVA change after long instrumentation and fusion for LL reconstruction.
