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.

Multicenter Study
Treatment of thoracic scoliosis: are monoaxial thoracic pedicle screws the best form of fixation for correction?
Multicenter retrospective cohort study of 100 consecutive patients. ⋯ Similar coronal and sagittal plane correction was achieved in thoracic adolescent idiopathic scoliosis with 3 different constructs. There was a trend toward improved correction of clinical rib hump deformity with MONO screw constructs compared with POLY screw constructs.
-
Retrospective review. ⋯ Patients with scoliosis and OTRC have a greater risk of adding-on proximally and of loss of correction with anterior-only instrumentation; they may also have less predictable lumbar correction from selective thoracic fusion. However, after combined surgery, they have results similar to those of more skeletally mature patients.
-
Retrospective study. ⋯ The distal end of a fusion for thoracic hyperkyphosis should include the SSV. Levels that include the first lordotic vertebra but not the SSV are not always appropriate to prevent postoperative distal junctional kyphosis.

An anatomic, epidemiologic study of lumbar and cervical arthrosis in cadaveric spines. ⋯ Concurrent lumbar and cervical arthrosis is a common condition. Lumbar arthrosis and advancing age are associated with cervical arthrosis independent of race and sex. Lumbar arthrosis precedes cervical arthrosis. These findings suggest an underlying systemic component for spinal osteoarthritis.
