Cervical artificial disc replacement (C-ADR): global perspectives on use and trends.
Evid Based Spine Care J
February 2012
Study Design: Cross-sectional survey.
Objectives: To obtain information from the global community regarding cervical artificial disc replacement (C-ADR) use and trends before and after US Food and Drug Administration (FDA) approval of devices in 2007 and summarize available information on utilization and government approval for devices.
Methods: Data on utilization and approval were sought from PubMed, Google, FDA, and manufacturers' websites.
Article Synopsis
- The study aimed to evaluate how factors like spinal injury level, timing of treatment, and cause of injury affect recovery after thoracic spinal cord injuries (SCIs).
- Out of 486 articles reviewed, only 10 studies provided relevant data, all categorized with low quality (LOE III) and highlighting a lack of comprehensive research on thoracic SCIs.
- Results indicated that lower thoracic injuries had fewer pulmonary issues, and early surgery could lead to shorter hospital stays, but overall, the evidence is insufficient to make strong conclusions about recovery outcomes.
Study Design: Systematic review.
Objective: To assess whether the presence or magnitude of postsurgical malalignment in the coronal (scoliosis) or sagittal plane (kyphosis/spondylolisthesis) affects the risk of cervical adjacent segment pathology (ASP).
Summary Of Background Data: ASP occurs in selected patients who have undergone surgical treatment for cervical spondylosis.
Study Design: Systematic review.
Objective: To review the literature on proximal junctional kyphosis (PJK) as a specific form for proximal adjacent segment pathology and report on the incidence, timing, risk factors, and effect on health-related quality of life (HRQOL) outcomes reported for PJK.
Summary Of Background Data: PJK is a complication of spinal deformity surgery that can compromise outcomes and necessitate revision surgery.
