We present the positional magnetic resonance imaging findings of a prospective case series of patients undergoing surgery with the Dynesys spinal stabilization device (Zimmer, Inc., Warsaw, IN). ⋯ In vivo, the Dynesys Stabilization System allows movement at the instrumented level, albeit reduced, with no significant increased mobility at the adjacent segments. There was reduction of the anterior disc height without a significant increase of the posterior disc height.

Comparative Study
Long-term results of one-level lumbar arthroplasty: minimum 10-year follow-up of the CHARITE artificial disc in 106 patients.
A retrospective chart and radiographic review. ⋯ This retrospective study demonstrates the safety and efficacy of the CHARITE Artificial Disc at one level, either L4-L5 or L5-S1, in the long-term. Clinical outcomes and the rate of return to work were excellent overall. The rate of adjacent-level disease requiring surgical intervention was considerably lower (2.8%) compared with reports in the literature for lumbar fusion. As with any surgical procedure, proper indications play a pivotal role in clinical success.

Case Reports Multicenter Study Comparative Study
Surgical strategy for cervical myelopathy due to ossification of the posterior longitudinal ligament: Part 2: Advantages of anterior decompression and fusion over laminoplasty.
Retrospective study of 27 patients who underwent anterior decompression and fusion (ADF) for treatment of cervical myelopathy due to ossification of the posterior longitudinal ligament (OPLL). ⋯ Although ADF is technically demanding and has a higher incidence of surgery-related complications, it is preferable to laminoplasty for patients with occupying ratio of OPLL > or =60%.

Case Reports Multicenter Study
Upper extremity palsy following cervical decompression surgery results from a transient spinal cord lesion.
Retrospective analysis. ⋯ The results of the present study support our hypothesis that the etiology of the palsy is a transient disturbance of the spinal cord following a decompression procedure. It appears to be caused by reperfusion after decompression of a chronic compressive lesion of the cervical cord. We recommend that physicians inform patients and surgeons of the potential risk of a spinal cord deficit after cervical decompression surgery.

Randomized Controlled Trial Multicenter Study
Neck collar, "act-as-usual" or active mobilization for whiplash injury? A randomized parallel-group trial.
Randomized, parallel-group trial. ⋯ Immobilization, "act-as-usual," and mobilization had similar effects regarding prevention of pain, disability, and work capability 1 year after a whiplash injury.
