OBJECT Infections following spine surgery negatively affect patient quality of life (QOL) and impose a significant financial burden on the health care system. Postoperative wound infections occur at higher rates following dorsal cervical procedures than ventral procedures. Quantifying the health outcomes and costs associated with infections following dorsal(More)
STUDY DESIGN Morphometric and volumetric analyses and virtual screw placement. OBJECTIVE The aim of the study was to (1) define the morphometric and volumetric dimensions of the laminae of C3-C7 and (2) analyze the feasibility of unilateral and bilateral translaminar screw placement at C3-C7. SUMMARY OF BACKGROUND DATA Previous studies on translaminar(More)
STUDY DESIGN Retrospective 1-year cost-utility analysis. OBJECTIVE To determine the cost-effectiveness of decompression with and without instrumented fusion for patients with grade I degenerative L4-L5 spondylolisthesis at 1-year follow-up. SUMMARY OF BACKGROUND DATA Despite its benefits to health outcomes, lumbar fusion is associated with substantial(More)
BACKGROUND CONTEXT Posterior cervical fusion (PCF) has been shown to be an effective treatment for cervical spondylosis, but is associated with a 9% complication rate and high costs. To limit such complications and costs, it is imperative that proper selection of surgical candidates occur for those most likely to do well with the surgery. Affective(More)
BACKGROUND CONTEXT Cervical disc arthroplasty (CDA) is a motion-preserving procedure that is an alternative to fusion. Proponents of arthroplasty assert that it will maintain cervical motion and prevent or reduce adjacent segment degeneration. Accordingly, CDA, compared with fusion, would have the potential to improve clinical outcomes. Published studies(More)
OBJECT Cost-effectiveness research in spine surgery has been a prominent focus over the last decade. However, there has yet to be a standardized method developed for calculation of costs in such studies. This lack of a standardized costing methodology may lead to conflicting conclusions on the cost-effectiveness of an intervention for a specific diagnosis.(More)
BACKGROUND CONTEXT C5 palsy is a debilitating postoperative complication of cervical decompression surgery. Although the prognosis is typically good, patients may be unable to perform basic activities of daily living, resulting in a decreased quality of life. No studies have investigated the quality-of-life and financial implications. PURPOSE The aim of(More)
BACKGROUND CONTEXT Some, smaller studies have investigated the effect of preoperative depression on postoperative improvement in quality of life (QOL). However, they have not used the Patient Health Questionnaire 9 (PHQ-9) in self-reported depression. PURPOSE To assess the effect of preoperative depression as measured by the PHQ-9 on postoperative(More)
BACKGROUND Cervical disc arthroplasty (CDA) is a novel motion-preserving procedure that is an alternative to fusion. The Mobi-C disc prosthesis, one of many Food and Drug Administration (FDA)-approved devices for CDA, is the only FDA-approved prosthesis for two-level CDA. Hence, it may allow for improved outcomes compared with multilevel fusion procedures.(More)
Thirty-six young adults (M age = 24.3 years) and 36 old adults (M age = 71.8 years) listened to four double-episode stories having either standard, interleaved, or scrambled structure. Two days later they were asked to recall the stories. Analysis of the mean number of nodes recalled revealed no age differences in the recall of standard and scrambled(More)
