Results of Total Cervical Disc Replacement with a Minimum Follow-up of 10 Years.

 In the present study, we present the results with at least 10 years of follow-up of the cervical disc prosthesis implanted in a single level.  Retrospective study of patients undergoing single-level total cervical disc replacement (TCDR). Clinical results included the neck disability index (NDI) and the visual analogue scale (VAS) in the preoperative period, one year postoperatively, and a minimum of 10 years of follow-up.

Minimum of 10-year follow-up of V-rod technique in lumbar spondylolysis.

Purpose: To describe and analyze the use of the V-rod technique described by Gillet to repair spondylolysis in both early and late postoperative periods.

Methods: Patients submitted to surgical correction of lumbar spondylolysis with a V-rod system were selected upon exclusion of adjacent disk degenerative changes and high-grade spondylolisthesis. A preoperative clinical (ODI and VAS) and radiological evaluation was performed, along with assessments on the early (clinical evaluation-up to 1 year) and late (clinical and radiological-at least 10 years) postoperative periods.

Paediatric cervical spine injures. Nineteen years experience of a single centre.

Purpose: This observational study aims to describe pediatric C-spine injuries from a level 1 trauma centre through a period of 19 years.

Methods: Clinical records of pediatric trauma patients admitted to a level 1 trauma centre between 1991 and 2009 were analyzed. Patients were stratified by age into groups A (8 or less) and B (9 to 16), and in lower (C0-C2) and upper (C3-C7) spine injuries.

Sagittal Correction and Reciprocal Changes After Thoracic Pedicle Subtraction Osteotomy.

Study Design: A retrospective clinical review.

Objective: To evaluate the sagittal correction efficacy of a thoracic pedicle subtraction osteotomy (PSO), to determine and predict changes at both the cervical and lumbar mobile unfused segments after whether an upper or lower level thoracic PSO.

Summary Of Background Data: Thoracic PSO is a technically challenging but increasingly valid procedure in the treatment of fixed thoracic deformities.

Epithelioid hemangioendothelioma presenting as a vertebral fracture.

Epithelioid hemagioendothelioma (EH) is a rare vascular tumor with an intermediate biological behavior between hemangioma and angiosarcoma. Vertebral location is even more rare, and because the number of reported cases of EH is small and the follow-up periods short, the best surgical treatment, the role of radiotherapy and chemotherapy, as well as the definitive prognosis are still not established. The authors report a case of EH which presented as a vertebral fracture with neurological impairment, where a percutaneous biopsy was inconclusive.
