Risk Factors for Early Recurrence After Transforaminal Endoscopic Lumbar Disc Decompression.

Background: Transforaminal endoscopic lumbar disc decompression (TELD) has emerged as a treatment alternative to open lumbar discectomy, but rates of herniated lumbar disc (HLD) recurrence after TELD are higher by comparison.

Objectives: We conducted this study to identify factors correlating with early HLD recurrence after TELD.

Study Design: Retrospective study.

Fracture of the L-4 vertebral body after use of a stand-alone interbody fusion device in degenerative spondylolisthesis for anterior L3-4 fixation.

Many studies attest to the excellent results achieved using anterior lumbar interbody fusion (ALIF) for degenerative spondylolisthesis. The purpose of this report is to document a rare instance of L-4 vertebral body fracture following use of a stand-alone interbody fusion device for L3-4 ALIF. The patient, a 55-year-old man, had suffered intractable pain of the back, right buttock, and left leg for several weeks.

Intraoperative discography for detecting concealed lumbar discal cysts.

Lumbar discal cyst is a rare cause of radiculopathy. Their exact pathogenesis and the optimal treatment modality remain unidentified. Depending on their location, discal cysts cannot always be easily identified intraoperatively.
