Cervical neurofibromatosis with tetraplegia: management by cervical suspensory traction.
A case report. ⋯ Cervical suspensory traction is a viable and safe adjunct technique for applying gradual and sustained effort to maximize postoperative correction in the treatment of NF-1 patients with severely rigid and large curves. This report should contribute to expanding the alternative method for the staged treatment strategy to complex abnormalities.

A cross-sectional magnetic resonance imaging (MRI) study. ⋯ Herniations were most likely in the subjects with recent onset or persistent (3-yr period) low back symptoms, although they were also detected in subjects with no symptoms. The clinical relevance of herniations on MRI remains to be evaluated in the context of symptoms.

Measurement of radiation dose from C-arm fluoroscopy during a simulated intraoperative use in spine surgery. OBJECTIVE.: To investigate scatter radiation doses to specific organs of surgeons during intraoperative use of C-arm fluoroscopy in spine surgery and to provide practical intraoperative guidelines. ⋯ The following factors could reduce radiation exposure during intraoperative use of C-arm; (1) distance from the patient, (2) C-arm configuration, (3) radioprotective equipments, (4) rotating the surgeons' eyes away from the patient, and (5) avoiding direct exposure of surgeons' hands.

A cross-sectional analysis of parents' and patients' perceptions of deformity- and brace-related stress regarding conservative treatment of adolescent idiopathic scoliosis. ⋯ Patients and parents perceive the emotional stress related to brace treatment in the same way; however, parents overestimate the assessment of stress levels related to body deformity. From the perspective of patients and parents, brace wearing increased the level of stress induced by the deformity alone. Complete assessment of conservative treatment should include evaluation of emotional stress from the perspective of patients and parents.

Numerical modeling and simulations of scoliotic spine instrumentation using monoaxial, uniaxial, polyaxial, and multiple-degrees-of-freedom (6DOF) postloading pedicle screws. ⋯ The bone-screw loads of different screws were significantly different. The descending order of bone-screw loads was monoaxial, uniaxial, polyaxial, and 6DOF screws. For patients with large and stiff spinal deformities or for patients with compromised bone quality, screws with more degrees of freedom offer better perspective to reduce bone-screw connection failure.
