Case Reports
Polyethylene wear debris and long-term clinical failure of the Charité disc prosthesis: a study of 4 patients.
A clinical case series of 4 patients undergoing anterior lumbar revision due to failure of total disc replacement surgery. ⋯ This study demonstrates the clinical significance of polyethylene wear debris and the potential for osteolysis with total disc replacements. The authors recommend that patients undergoing lumbar disc arthroplasty receive long-term follow-up to monitor the wear and functional status of their implants.
-
A prospective study of patients undergoing lumbar disc herniation surgery. ⋯ Patients undergoing lumbar disc herniation surgery are mostly satisfied with provided care before and after surgery, however, less satisfied with information provided. Further, patients with preoperative positive expectations on work return and realistic expectations on pain and physical recovery have a greater chance to be satisfied with the surgical results.
-
A prospective nonrandomized, longitudinal cohort study. ⋯ The results indicate the potential of radiosurgery in the treatment of patients with spinal metastases, especially those with solitary sites of spine involvement, to improve long-term palliation.
-
A population-based, prospective cohort. ⋯ Emotional distress is a predictor for low back disability in persons with earlier LBP, but not in persons without. To prevent low back disability, emotional distress should be considered and treated in persons with LBP.

In vitro biomechanical flexibility experiment studying 5 sequential conditions. ⋯ Direct fixation of the pars ineffectively limits flexion and extension after a Type II hangman's fracture. If pars screw fixation can be achieved, posterior C2-C3 fixation more effectively stabilizes a hangman's fracture than anterior cervical plating.
