Prevalence of lumbar total disc replacement candidates in a community-based spinal surgery practice.

Study Design: This study was a retrospective record review of consecutive lumbar surgical patients seen by one surgeon in a private, community setting over a 15-month period.

Objective: The purpose of this study was to evaluate the potential frequency that candidates for total disc replacement (TDR) might be seen in a community-based spinal surgery practice.

Summary Of Background Data: The impact of TDR technology on the practice of spine surgery remains uncertain.

The prevalence of indications and contraindications to cervical total disc replacement.

Background Context: Although the prevalence of indications and contraindications to lumbar total disc replacement (TDR) has been evaluated, no study to date has quantified the potential candidacy for cervical disc replacement in practice.

Purpose: To report the potential candidacy rate for cervical TDR from both an academic and private practice spine surgery setting.

Study Design/setting: Retrospective case series.

Substance P-containing nerves within the human vertebral body. an immunohistochemical study of the basivertebral nerve.

Background Content: The basivertebral nerve provides innervation to the trabecular bone of the vertebral body. The function of this nerve is not known.

Purpose: The study was undertaken to better define the anatomic origin of this intraosseous nerve and to determine if this nerve contains substance P.

Clinical value of routine preoperative magnetic resonance imaging in adolescent idiopathic scoliosis. A prospective study of three hundred and twenty-seven patients.

Background: The prevalence of intraspinal pathology associated with scoliosis has been reported to be as high as 26% in some series, and, on the basis of this finding, preoperative magnetic resonance imaging is used in the screening of patients with adolescent idiopathic scoliosis. However, this practice continues to be highly controversial. In order to better resolve this issue, we performed what we believe to be the largest prospective study to evaluate the need for preoperative magnetic resonance imaging in patients with adolescent idiopathic scoliosis requiring arthrodesis of the spine.
