Clinical cohort. ⋯ The results suggest a strong adherence to radiography guidelines for patients with a new episode of low back pain who presented to chiropractic teaching clinics. Although a high proportion of patients had red flags, radiography utilization was lower than rates reported in previous studies suggesting that adherence to guidelines may help prevent unnecessary radiography.

A case of acquired lumbar spondylolysis following lumbar disc arthroplasty L5-S1 in an 40-year-old woman and review of the literature. ⋯ Spine surgeons should be aware of the possibility of lumbar disc arthroplasty to induce acquired spondylolysis impairing good clinical results.

Retrospective review of cases at a single institution from 1998 to 2005. ⋯ Combined spinal cord transection and spinal fusion allowed an average correction of kyphosis by 81.9 degrees . The complication rate was 89%, with wound concerns being the most significant. Additionally, 22% of patients required shunt revision within 6 weeks of surgery. We attribute this to alteration of CSF dynamics resulting from loss of CSF absorption and flow-buffering capacity below the level of the spinal cord transection.

A prospective study involving 56 patients with cervical spondylotic myelopathy (CSM) was conducted. ⋯ Outcomes of mild forms of CSM during nonsurgical treatment were generally good as shown by average JOA scores. The only prognostic factor for mild forms of CSM was circumferential spinal cord compression in the maximum compression segment on axial MRI. Surgical treatment can be considered for patients with this prognostic factor.

Fibrin sealant (FS) combined with or without growth factor was used to improve the micro-architectural and biomechanical properties of vertebral body in osteoporotic ovine spine. ⋯ The use of bBMP/FS in the treatment of vertebral osteoporosis in an attempt to enhance bone strength merits further study.
