This is a retrospective review on the application of the authors' technique of atlantoaxial lateral mass plate and screw fixation on a rare subset of patients having mobile and reducible atlantoaxial subluxation in the presence of occipitalized atlas. ⋯ Although lateral mass plate and screw fixation in the presence of occipitalized atlas is technically a relatively difficult and anatomically a precise surgical procedure, the firm and segmental stabilization that it provides offers an optimum situation for bony fusion.

Comparative Study
Changes in the cross-sectional area of multifidus and psoas in patients with unilateral back pain: the relationship to pain and disability.
Prospective, cross-sectional observational study. ⋯ Atrophy of multifidus has been used as one of the rationales for spine stabilization exercises. The evidence of coexisting atrophy of psoas and multifidus suggests that a future area for study should be selective exercise training of psoas, which is less commonly used in clinical practice.

Comparative Study
Complications associated with lumbar laminectomy: a comparison of spinal versus general anesthesia.
A case-controlled, comparative study of 400 patients undergoing lumbar surgery, treated with either spinal or general anesthesia. An independent observer analyzed outcomes. ⋯ For patients undergoing decompressive lumbar surgery, spinal anesthesia is at least comparable to general anesthetic with respect to complications. Specific advantages to spinal anesthesia include decreased nausea and antiemetic requirements, reduced analgesic requirements, and reduced overall complication rate.

Case Reports Comparative Study
New technique in congenital scoliosis involving fixation to the pelvis after hemivertebra excision.
The authors conducted a retrospective study involving description of a new surgical technique. ⋯ This prospective study demonstrates a successful surgical technique for spinal stabilization after congenital hemivertebra excision in infants and young children with relatively small and soft bones when standard constructs like pedicle screws may not be optimal devices. Coronal and sagittal balance (restoration with improvement of lordosis) was successfully achieved in all cases.

Comparative Study
Occupational gonadal and embryo/fetal doses from fluoroscopically assisted surgical treatments of spinal disorders.
Simulation of lumbar spine fluoroscopy used during surgical treatments of spinal disorders on a humanoid phantom and monitoring of the scattered radiation levels. ⋯ Radiogenic genetic and embryo/fetal risks resulting from occupational exposure due to fluoroscopically assisted surgical treatments of spinal disorders are well within tolerance levels provided that rigorous confinement to all pertinent occupational dose constraints is established.
