Comparative Study
Disc herniation-related back pain impairs feed-forward control of paraspinal muscles.
A comparative study of lumbar paraspinal muscle reflexes during sudden upper limb loading in healthy control subjects and patients with sciatica. ⋯ The results provide evidence for impaired feed-forward control of lumbar muscles in patients with sciatica.

Comparative Study
Evaluation of various evoked potential techniques for spinal cord monitoring during scoliosis surgery.
This prospective study compared the outcomes of different evoked potential (EP) techniques for intraoperative spinal cord monitoring. ⋯ CSEP and CMEP are recommended for routine monitoring, so that both ascending and descending tracts are monitored. If adequate signals for either of these proposed monitoring methods cannot be easily obtained, SSEP can substitute for CSEP, whereas SCEP can substitute for CMEP.

One case is reported in which a failed anterior fusion for Grade 4 spondylolisthesis was treated with a vascularized fibular strut graft using a posterior approach. ⋯ A vascularized fibular strut graft is a feasible alternative in the treatment of severe spondylolisthesis. No complications were encountered in the involved patient. Future application may include salvage reconstruction of failed arthrodesis or in individuals with systemic conditions that may impair graft incorporation using more standard techniques.

This is a retrospective study of surgical correction of thoracolumbar kyphosis caused by ankylosing spondylitis. ⋯ Transpedicular wedge osteotomy can effectively and safely correct kyphotic deformity of the thoracolumbar spine caused by ankylosing spondylitis, regardless of rigidity of the spinal curves. Two-level osteotomy can provide sufficient correction for severe cases.

A case report of anaerobic vertebral osteomyelitis after anal dilatation. ⋯ Bacteroides fragilis hematogenous osteomyelitis is a rare entity. This is the first reported case of such disease after anal dilatation.
