Randomized Controlled Trial Comparative Study Clinical Trial
Does the method of injection alter the outcome of epidural injections?
A pilot study involving 44 patients with low back and leg pain was performed to compare the relative efficacy of epidural caudal and lumbar injections.

Trigeminal sensory impairment is frequent in whiplash cases. The pathophysiology is unknown. The purpose of the present investigation was to prospectively study the trigeminal sensibility for temperature and vibration and to evaluate their relationship with the clinical symptoms. ⋯ Sensory disturbances over the trigeminal skin area persisted over the years ( r = 0.764. p < 0.000). At follow-up, a significant correlation ( r = 0.614, p < 0.000) was found between the sensory disturbances and the symptoms related to the central nervous system, whereas no significant relationship was found with the musculoskeletal symptoms. Trigeminal sensory impairment can either be explained by dysfunction in the central nervous system or by inhibitory mechanisms secondary to pain.

No previous study has compared the complications between anterior/posterior and transforaminal interbody fusions. We performed a retrospective analysis of 164 patients to compare the complications and associated predictive factors of the two techniques of circumferential lumbar fusion. Fifty-three had same-day anterior/posterior fusion (group 1), and 111 had transforaminal interbody fusion (group 2). ⋯ In group 1, body mass index was independently associated with complications. In group 2, both hospital stay and adjunctive treatment were predictive of complications. Transforaminal lumbar interbody fusion is the preferred technique because it is associated with shorter operating time, less blood loss, shorter hospital stay, and lower incidence of complications.

The sagittal and frontal profiles of the entire spine are poorly studied in lumbosacral spondylolisthesis. It was the purpose of this study to further investigate these profiles. Standing posterior-anterior and lateral radiographs in 24 children with lumbosacral spondylolisthesis were reviewed (18 isthmic, 6 congenital). ⋯ Thoracic kyphosis was less in those with scoliosis (21 +/- 25 degrees versus 33 +/- 25 degrees, p = 0.033). In children with lumbosacral spondylolisthesis, the sacrum becomes more vertical as the slip worsens. As the sacrum becomes more vertical, the thoracic spine becomes more lordotic, which is likely an adaptive mechanism used by the body to maintain forward visual gaze.
