Long-term systemic metal distribution in patients with stainless steel spinal instrumentation: a case-control study.
Case-control study. ⋯ Cr testing is suggested as a reliable marker for the malfunctioning assessment and as a support for standard procedures, especially with doubtful diagnosis. Furthermore, high levels of Cr ions were observed in female patients. This finding deserves attention especially when counseling young fertile women.

Effect of lamina open angles in expansion open-door laminoplasty on the clinical results in treating cervical spondylotic myelopathy.
A retrospective study. ⋯ In different angles of lamina open-door, the improvement rate of neurological function after surgery had no statistically significant difference between 2 groups. When the open-door angle is maintained between 15 and 30 degrees, it can reduce the incidence of C5 palsy in the hinge side and AS, but we should prevent reclosure of the lamina open-door.

Cost per quality-adjusted life year gained of revision fusion for lumbar pseudoarthrosis: defining the value of surgery.
Single cohort study of patients undergoing revision fusion for lumbar pseudoarthrosis. ⋯ Revision arthrodesis was associated with improved 2-year quality of life in patients with pseudoarthrosis-related back pain. Nevertheless, in our experience revision surgery was shown to be marginally cost-effective at $118,945 per QALY gained.

Cement augmented anterior odontoid screw fixation is biomechanically advantageous in osteoporotic patients with Anderson Type II fractures.
A biomechanical human cadaveric study. ⋯ Cement augmentation for fixation of osteoporotic type II odontoid fractures showed biomechanical advantages. It was also shown that cement augmentation of the newly developed screw is technically easy and safe under in vitro conditions. The technique might be useful with regard to the surgical treatment of elderly patients with osteoporotic odontoid fractures.
