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 cross-sectional study. ⋯ Facet tropism was more significantly observed at levels with VRS. On the convex side of the main curve, facet joints at levels with VRS were more coronally oriented. A larger Cobb angle and severe facet tropism in degenerative scoliosis should be considered to be related to VRS.

Krag versus Caudad trajectory technique for pedicle screw insertion in osteoporotic vertebrae: biomechanical comparison and analysis.
To compare in detail the effects of pedicle screw insertion in osteoporotic vertebrae via Krag and Caudad trajectory techniques. ⋯ Pedicle screws inserted in osteoporotic lumbar vertebrae using the Caudad trajectory displayed significantly higher biomechanical strength than those inserted using the Krag trajectory, especially during early fixation. Stability of pedicle screw fixation using the Caudad trajectory technique can be estimated by QCT.
