Background: Surgical treatment of intrathoracic meningoceles, commonly associated with neurofibromatosis type 1 (NF1), aims to reduce sac size for symptomatic relief. The procedures can be divided into cerebrospinal fluid diversion and definitive repair. The authors describe the management of an intrathoracic meningocele in a 56-year-old female with preexisting NF1.

View Article and Find Full Text PDFBackground Context: Disappearing bone disease (DBD) is a rare idiopathic musculoskeletal disorder that is distinguished by bone resorption without bone formation, vascular or lymphatic vessel proliferation, and soft-tissue swelling. Long-term follow-up of a patient with DBD has rarely been reported in the literature.
Purpose: The following is a case report of a female patient with DBD of the humerus and the spine who was followed for 42 years, documenting the progression of the disease and outcomes.
Background Context: The value of scoliosis screening has been recently shown in a multicenter randomized controlled trial. However, the long-term sustainability of the clinical effectiveness of scoliosis screening as a routine health service remains unknown.
Purpose: The aim of this study was to assess the sustainability of the clinical effectiveness of school scoliosis screening.

Study Design: A case report.
Objective: To report a rare case of acute spinal subdural hematoma (SSH) complicating lumbar spine surgery, its characteristic presenting symptoms, diagnostic imaging, possible cause, and pitfall in management.
Methods: A 59-year-old woman with lumbar spinal instability and stenosis underwent laminectomy and decompression at L3-L5 with instrumentation and fusion from L3-S1.
Study Design: A prospective cohort study of Cobb angles (CA) and apical vertebral rotations (AVR) in 25 patients who had adolescent idiopathic scoliosis.
Objective: To assess in vivo the concomitant vertebral derotation occurring with correction of scoliosis deformity as a result of coupling effect by using the fulcrum bending radiograph and to assess whether the fulcrum bending radiograph can predict the amount of postoperative apical derotation when no additional intraoperative apical derotation maneuver is used.
Summary Of Background Data: Adolescent idiopathic scoliosis (AIS) is a 3-dimensional coupling deformity.
Background: Scoliosis in skeletally immature children is often treated by implantation of a rod to straighten the spine. Rods can be distracted (lengthened) as the spine grows, but patients need many invasive operations under general anaesthesia. Such operations are costly and associated with negative psychosocial outcomes.

As such, we assessed a single institute's experience in the management of large PTCs (>35 degrees) in patients with adolescent idiopathic scoliosis (AIS) who were either fused or not fused. A retrospective radiographic analyses of 30 consecutive AIS patients with double thoracic curves who underwent PSF with a minimum of 2 years' follow-up were included for review.

The long-term natural history of the progression of spinal deformity, particularly scoliosis, and associated complications in EDS patients remains relatively unknown.
Purpose: To assess the progression of spinal deformity and associated complications in a patient with EDS, who was not surgically treated for her spine condition and was followed up for 20 years.
Study Design: A retrospective review of infective spondylitis patients assessed at a major, tertiary referral centre in Hong Kong.
Objective: To assess the prevalence, risk factors, clinical features, and prognostic outcomes associated with tuberculous spondylitis to that of pyogenic spondylitis in Southern Chinese treated at a single institution.
Summary Of Background Data: Previous studies in Asia suggest that tuberculous spondylitis is the predominant infection unless proven otherwise.
Background: The fulcrum bending radiograph accurately predicts scoliosis curve correction in patients with thoracic adolescent idiopathic scoliosis who are managed with hooks. We assessed the predictive value of the fulcrum bending radiograph in the context of alternate-level pedicle screw fixation of the scoliotic spine.
Methods: A prospective radiographic analysis of patients with thoracic adolescent idiopathic scoliosis who were managed operatively with alternate-level pedicle screw fixation at a single institution was performed.
The gait outcome measures used in clinical trials of paraplegic locomotor training determine the effectiveness of improved walking function assisted by the functional electrical stimulation (FES) system. Focused on kinematic, kinetic or physiological changes of paraplegic patients, traditional methods cannot quantify the walking stability or identify the unstable factors of gait in real time. Up until now, the published studies on dynamic gait stability for the effective use of FES have been limited.

However, published studies on dynamic gait stability for the effective use of FES are limited. This paper introduces a new risk-tendency graph (RTG) technique to analyze and process gait stability in FES-assisted paraplegic walking.
