BACKGROUND Anterior cervical discectomy and fusion (ACDF) is the gold standard for treating symptomatic cervical disc degeneration. Cervical total disc replacements (TDRs) have emerged as an alternative for some patients. The purpose of this study was to evaluate the safety and effectiveness of a new TDR device compared with ACDF for treating single-level cervical disc degeneration. METHODS T...

1. Introduction Adjacent segment degeneration (ASD) has been reported as the one of late serious complication after spinal fusion surgery [1-3]. Presumably, the immediate rigidity produced by instrumentation causes more stress leading to accelerated degeneration at adjacent levels [2]. Many previous studies have been corroborated a trend toward earlier development of ASD with instrumentation as...

STUDY DESIGN Retrospective radiographic analysis. OBJECTIVE To retrospectively review a group of patients undergoing anterior cervical discectomy and fusion (ACDF) to determine the relative risk of adjacent level disc degeneration after incorrect needle localization. SUMMARY OF BACKGROUND DATA The needle puncture technique is a well-established method to cause disc degeneration in experimen...

Spinal rigid instrumentations have been used to fuse and stabilize spinal segments as a surgical treatment for various spinal disorders to date. This technology provides immediate stability after surgery until the natural fusion mass develops. At present, rigid fixation is the current gold standard in surgical treatment of chronic back pain spinal disorders. However, such systems have several d...

STUDY DESIGN A retrospective study. PURPOSE We investigated the risk factors in adjacent segment degeneration (ASD) after more than 5 years of follow-up of lumbar spinal fusion. OVERVIEW OF LITERATURE There are many concerns regarding ASD followed by lumbar spinal fusion. However, there is a great deal of dispute about the risk factors. METHODS A total of 55 patients who were followed up ...

OBJECTIVE To determine the outcome of posterolateral fusion (PLF) for patients over 70 years of age with degenerative lumbar spinal disease. METHODS The authors reviewed 18 patients (13 women and 5 men) over 70 years of age who underwent PLF with a minimum 2-years follow-up at a single institution. The parameters for analysis were clinical outcome, intraoperative bleeding, operating time, tra...
