Lower incidence of dysphagia with cervical arthroplasty compared with ACDF in a prospective randomized clinical trial.

Study Design: The current study of 251 consecutive 1-level anterior cervical reconstructions was undertaken to compare the incidence of dysphagia between cervical disk replacement and conventional anterior cervical fusion and instrumentation.

Objectives: This is a report of 251 patients from 5 investigational centers in the Food and drug Administration's prospective, randomized porous-coated motion (PCM) trial using a validated dysphagia outcomes instrument. The dysphagia data for both PCM and anterior cervical diskectomy and fusion (ACDF) patients were reviewed from 5 centers to (1) compare the severity of dysphagia, (2) compare the postoperative incidence of dysphagia, and (3) to compare the resolution of perioperative dysphagia.

Prospective controlled trial of STAR total ankle replacement versus ankle fusion: initial results.

Background: Mobile-bearing ankle replacements have become popular outside of the United States over the past two decades. The goal of the present study was to perform a prospective evaluation of the safety and efficacy of a mobile-bearing prosthesis to treat end stage ankle arthritis. We report the results of three separate cohorts of patients: a group of Scandanavian Total Ankle Replacement (STAR) patients and a control group of ankle fusion patients (the Pivotal Study Groups) and another group of STAR total ankle patients (Continued Access Group) whose surgery was performed following the completion of enrollment in the Pivotal Study.

Cervical disc replacement in patients with and without previous adjacent level fusion surgery: a prospective study.

Study Design: Prospective 6-center study. OBJECTIVE.: To evaluate outcomes of cervical disc replacement performed adjacent to a prior cervical fusion.
