Comparative Study
Comparison of results of total disc replacement in postdiscectomy patients versus patients with no previous lumbar surgery.
Data for this study were collected as part of a prospective Food and Drug Administration regulated IDE trial for the ProDisc total disc replacement. ⋯ The results of this study indicate that the outcome of TDR is not compromised among patients witha history of previous discectomy. This finding supports TDR as a viable treatment for patients with symptomatic disc degeneration arising from a previously operated lumbar disc.

Retrospective case series. ⋯ The prevalence of increased proximal junctional flexion was 9.2%. No significant risk factors were identified. Total Scoliosis Research Society-22r scores were similar for groups with normal and increased proximal junctional flexion at follow-up.

A retrospective analysis of 59 patients operated for excision of soft highly migrated intracanal lumbar disc herniations by percutaneous endoscopic foraminoplasty. ⋯ Foraminoplastic-PELD is safe and effective procedure for surgical treatment of soft migrated herniations. The results are comparable to results of open discectomy.
