Spine
-
Eight cases of fibrous dysplasia (FD) of the mobile spine treated surgically at the same center were retrospectively reviewed. ⋯ The radiological features of spinal FD may be atypical. The rate of correct preoperative pathological diagnosis by computed tomography-guided biopsy was low for patients with suspected spinal FD. Vertebroplasty is probably a valuable therapeutic option for spinal FD with pathological fractures. Limited decompression and stability with vertebroplasty might be recommended for patients with neurological deficits.

This was a cross-sectional study. ⋯ The modified LEFS had satisfactory psychometric properties in patients with LBP and could serve as a supplementary outcome measure to assess their activity limitations.

Biomechanics of spinal hemiepiphysiodesis for fusionless scoliosis treatment using titanium implant.
In vitro study of the effect of hemiepiphyseal implant on biomechanical properties of porcine thoracic motion segments. ⋯ Implantation of a titanium clip-screw construct decreased range of motion by less than one-fifth, increased stiffness by one-third or less, and decreased the neutral zone by less than one-half. Range of axial translation decreased on the instrumented side and increased contralaterally. This study suggests that most of the flexibility of the spine is preserved in the immediate postoperative period after implantation of the spinal hemiepiphyseal construct.

Case report. ⋯ Isthmic spondylolisthesis must be considered as a cause within VBI. Surgery presents good results.

Retrospective case-control study. ⋯ This is the most detailed comparison of coccygeal morphology and morphometry in adults with and without coccydynia investigated using cross-sectional imaging. Anatomical differences in joint fusion and coccygeal curvature may either predispose to the development of coccydynia or arise as a result of this condition.
