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.

A matched cohort comparison of adult idiopathic scoliosis (AdIS) patients treated with all pedicle screw constructs compared to hook/hybrid constructs. ⋯ Pedicle screw correction of AdIS is safe and effective. Compared to hook/hybrid constructs, these patients displayed significantly improved correction of the major curve (even in the absence of anterior releases), maintenance of thoracic kyphosis, and a lower revision rate. Similar SRS scores and blood loss were noted. The hook/hybrid patients had significantly longer operative times. The use of BMP-2 in 7 patients and TLIF/ALIF also in 7 of the pedicle screw patients may have decreased the need for revision surgery up to the latest follow-up.

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.

Study to determine the internal consistency and validity of adapted German version of Scoliosis Research Society-22 (SRS-22) questionnaire. ⋯ The adapted German version of the SRS-22 questionnaire can be used to assess the outcome of treatment for German-speaking patients with idiopathic scoliosis.

Prospective clinical study. ⋯ When performing a prone thoracoscopic release for severe thoracic deformity, excellent coronal plane correction is achieved. There does not appear to be any detrimental effect on pulmonary function when a prone thoracoscopic release using double lung ventilation is added to a PSFI. This technique can be efficacious in achieving excellent deformity correction without adversely affecting pulmonary function and is recommended when treating severe spinal deformity. Adding a thoracoplasty provided a negative effect on pulmonary function and limited the benefits of performing a thoracoscopic release to the PSFI patients.
