The purpose of this study is to report a new technique and assess clinical outcome of compressive fractures with posterior vertebral defect treated by percutaneous vertebroplasty combined with the spinal external fixator. ⋯ The preliminary results are encouraging, showing that the spinal external fixator combined with percutaneous vertebroplasty was a safe and effective method to treat the osteoporotic compressive fractures with posterior vertebral defect.

To report the radiological predictors of kyphotic deformity in osteoporotic vertebral compression fractures (OVCF). ⋯ Progressive segmental kyphotic collapse following an OVCF seems unavoidable. Patients with TL junction and superior endplate fracture are probably at the highest risk for significant segmental kyphotic deformity.

Failure to select the appropriate lowest instrumented vertebra (LIV) in selective lumbar fusion (SLF) for thoracolumbar/lumbar curves (LC) can result in adding-on in the lumbar curve (LC) or the need for fusion extension due to a decompensating thoracic curve (TC). The selection criteria that predict optimal outcomes still need to be refined. The objectives of the current study were to identify risk factors for failure of anterior scoliosis correction and fusion (ASF) as well as predictors of optimal outcomes and ASF efficacy for SLF. ⋯ A high chance of achieving a target LC ≤ 20° and a low risk of revision was dependent on LC-bending, preoperative LC and TC, and a LIV at SV-1 with non-parallel LIVDA. Our risk model analysis may support the selection of a safe LIV to achieve the target LC.
