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.

Osteoporotic vertebral fractures are a frequently encountered clinical problem, and like other fractures, they may develop nonunion that can often go unrecognized. The aim of this study is to review the related articles reporting the osteoporotic vertebral fracture nonunion and discuss the radiological characteristics, diagnosis, and treatment of osteoporotic vertebral fractures.

A retrospective study. ⋯ Single-level cervical TDR with Prestige LP obtained satisfactory clinical outcomes and partially restored the natural cervical kinematics. At instrumented level, the deviated COR had a negative correlation with the flexion-extension ROM.

A retrospective clinical data analysis. ⋯ The location of ONL commonly corresponds to the most stenotic level of the spinal canal. The location of ONL also correlates with the level of osteophyte formation and intervertebral disc degeneration, indicating that ONL has correspondence to instability-related cervical pathological changes in cervical spondylosis.
