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.

Comparative StudyComparative effectiveness of minimally invasive versus open transforaminal lumbar interbody fusion: 2-year assessment of narcotic use, return to work, disability, and quality of life.
Retrospective cohort comparison between minimally invasive (MIS) and open transforaminal lumbar interbody fusion (TLIF). ⋯ Both MIS-TLIF and open-TLIF provide long-term improvement in pain, disability, and EuroQol-5D in patients with back and leg pain from grade I degenerative spondylolithesis. However, MIS-TLIF may allow for shortened hospital stays, reduced postoperative narcotic use, and accelerated return to work, reducing both direct medical costs and indirect costs of lost work productivity associated with TLIF procedures.

Comparison of surgical outcomes of lenke type 1 idiopathic scoliosis: vertebral coplanar alignment versus derotation technique.
Prospective clinical study. ⋯ In treating thoracic scoliosis, the VCA technique could achieve as good correction and clinical outcome as the derotation technique. The advantage lies in its superior renormalization effect of thoracic kyphosis compared with the derotation technique from the concave side.

Clinical evaluation of anterior screw fixation for elderly patients with type II odontoid fractures.
A retrospective study of elderly patients who underwent anterior screw fixation for type II odontoid fractures between 2000 and 2009 was conducted. ⋯ Anterior screw fixation can be performed safely in elderly patients with type II odontoid fracture, and the clinical outcomes of this procedure were satisfactory. High fusion rates, low postoperative complications, and maintenance of cervical motion were acquired. The anterior screw fixation can be a reliable and reasonable treatment for type II odontoid fractures in the elderly patients.
