Spine
-
A retrospective, comparative follow-up study. ⋯ Circumferential fusion provided significantly better long-term clinical, radiographic, and SRS total score than posterolateral or anterior fusion for high-grade isthmic spondylolisthesis.

Comparative Study
An evaluation of image-guided technologies in the placement of percutaneous iliosacral screws.
A surgical simulation study in human cadaver spine specimens was conducted to evaluate the accuracy of 3 different surgical navigation systems compared to standard fluoroscopy in the percutaneous placement of iliosacral screws. ⋯ Computer-assisted fluoroscopy based image navigation appears to be more accurate than standard fluoroscopy in placing these screws. However, errors may occur with all techniques. Further refinement in registration procedures may highly improve the accuracy of percutaneous screw placement in a variety of spinopelvic procedures.

Comparative Study Controlled Clinical Trial
Head repositioning accuracy in patients with whiplash-associated disorders.
Controlled study, measuring head repositioning error (HRE) using an electrogoniometric device. ⋯ In patients with WAD, range of motion and head repositioning accuracy were reduced. However, the differences were small. Vision suppression and task type influenced HRE.

Case Reports
Segmental spinal dysgenesis: case report of a 50-year follow-up after surgery at age 3 years: case report.
Case report with ultra long-term follow-up. ⋯ Arthrodesis at age 3 years provided an optimal ultra long-term follow-up.
