Combined posterior and delayed staged mini-open anterior short-segment fusion for thoracolumbar burst fractures.
A prospective study. ⋯ This combined procedure is less invasive than the conventional combined one, and finally achieves shorter stabilization, resulting in preservation of motion segments. It thus seems to be a reasonable treatment option for thoracolumbar burst fractures.

Treatment of thoracolumbar burst fractures by means of anterior fusion and cage.
Retrospective case series. ⋯ Anterior thoracolumbar decompression and fusion secured with an anterior mesh cage and instrumentation in thoracolumbar burst fractures provided excellent immediate reduction of post-traumatic local kyphosis.

Optimization of radiation exposure and image quality of the cone-beam O-arm intraoperative imaging system in spinal surgery.
Retrospective study. ⋯ The radiation doses of the O-arm system can be reduced 5 to 13 times without negative impact on image quality with regard to information required for spinal surgery.

Analysis of concave and convex rib-vertebral angle, angle difference, and angle ratio in patients with lenke type 1 main thoracic adolescent idiopathic scoliosis treated by observation, bracing or posterior fusion, and instrumentation.
Retrospective review. ⋯ Convex RVA was smaller than concave RVA between T1 and T10 in all groups of patients. RVAD and RVARa values in the scoliotic segment were greater in patients with untreated scoliosis more than 40 degrees than in patients with an untreated deformity of <25 degrees or in patients, treated by bracing or surgery, with a residual curve of <25 degrees. These measurements are a useful tool in the armamentarium of the surgeon treating spinal deformities and could be used to better characterize the deformity and/or to evaluate effects of brace or surgical treatment.

Influence of hinge position on the effectiveness of expansive open-door laminoplasty for cervical spondylotic myelopathy.
A prospective study. ⋯ Our results indicate that proper inward shift of the hinge can ensure effectiveness of surgical decompression, avoid an excessive backward shift of the spinal cord, reduce the incidence of C5 palsy, and alleviate the severity of axial symptoms. In addition, an inward shift should be cautious and contraindicated in patients with fluorosis cervical stenosis, ossification of posterior longitudinal ligament, and ossification of ligament flavum.
