Three-dimensional analysis of thoracic apical sagittal alignment in adolescent idiopathic scoliosis.
Retrospective review of a series of adolescent idiopathic scoliosis patients. ⋯ This 3D analysis of thoracic scoliosis demonstrated a consistent loss of kyphosis within the 5 thoracic apical vertebrae. The true apical sagittal profile was found to be overestimated by an average of 10 degrees as compared to the perceived alignment from standard lateral radiographs.

Outcomes of muscle-preserving interlaminar decompression (MILD) for the lumbar spine are reported. ⋯ In MILD for the lumbar spine, damage to the posterior stabilizing structures such as the intervertebral facet joints, paravertebral muscles, thoracolumbar fascia, supra- and interspinous ligaments, can be minimized, while preserving the function of the spinous processes as lever arms for lumbar extension.

Review Case Reports
Acquired hemophilia a in a patient with lumbar disc herniation: a case report and review of the literature.
To summarize the clinical manifestations and treatment of acquired hemophilia A in a patient with lumbar disc herniation. ⋯ Surgical operation may be a factor contributing to acquired hemophilia A, which, to our knowledge, has not been reported in the literature. Diagnosis of acquired hemophilia requires clinical acumen and any patient who presents with bleeding and a prolonged activated partial-thromboplastin time should be considered. Initial hemodynamic stabilization followed by treatment with immunosuppressive therapy is straightforward and highly successful.

Comparative Study
Computed tomography evaluation of rotation correction in adolescent idiopathic scoliosis: a comparison of an all pedicle screw construct versus a hook-rod system.
Retrospective review with historical cohort. ⋯ Our study finds axial rotation correction using APSs and a direct vertebral body derotation technique was significantly greater than that obtained with the HR construct.
