The toros of fresh cadavers were used to create endoscopic channels through the iliac wings to gain access to the L5-S1 disc and foramen. The spine and pelvis then were dissected out en bloc, and the anatomic relationships were studied. ⋯ The results of this study suggest that it is possible to access the L5-S1 disc and foramen through the ilium without injuring important structures. It would be necessary to conduct a study based on an animal model and to evaluate the results before using this procedure in a clinical situation.

Eight children in whom atlantoaxial dislocation had developed underwent occipitocervical fusion using a rectangular rod. The postoperative results are presented, and the postoperative growth and deformation of the cervical spine were determined radiographically. ⋯ Occipitocervical fusion with a rectangular rod is useful for treating atlantoaxial dislocation in children and yields excellent results because of the firm internal fixation it achieves. This surgery induced no apparent postoperative spinal deformations.

A topographic and histologic study was done to describe the location of the lumbar epidural fat and to find potential tissular specificities. ⋯ Posterior lumbar epidural fat is not a simple incidental tissue and shows specific histologic features: sliding spaces and rarefaction of connective tissue that could explain semifluid features of the tissue. These characteristics suggest a functional role of posterior epidural fat in the lumbar spinal unit.

This study evaluated the long-term results of Klippel-Feil syndrome in patients with congenital scoliosis. ⋯ Only a small number of patients with Klippel-Feil syndrome and congenital scoliosis developed cervical symptoms. No fusion pattern that placed the patient at greater risk for developing symptoms could be identified. Factors that did lead to a greater incidence of cervical symptoms were fusion to the cervicothoracic junction and congenital cervical stenosis.

A prospective, population-based cohort study of working adults. ⋯ People dissatisfied with work are more likely to report low back pain for which they do not consult a physician, whereas lower social status and perceived inadequacy of income are independent risks for working people to seek consultation because of low back pain.
