BACKGROUND Adjacent segment degeneration is a long-term complication of arthrodesis. However, the incidence of adjacent segment degeneration varies widely depending on the patient's age and underlying disease and the fusion techniques and diagnostic methods used. QUESTIONS/PURPOSES We determined (1) the frequency of adjacent segment degeneration and(More)
BACKGROUND Concerns have been raised regarding residual symptoms of caudal segment (L5-S1) degeneration that may affect clinical outcomes or require additional surgery after isolated L4-5 fusion, especially if there is pre-existing L5-S1 degeneration. This study aimed to evaluate the L5-S1 segment after minimally invasive lumbar interbody fusion at the L4-5(More)
OBJECTIVE Percutaneous endoscopic lumbar discectomy (PELD) with remarkable advancements has led to successful results comparable with open discectomy; however, its application in herniated disc (HD) with migration is still challenging and technically demanding. The purpose of this study is to propose various strategies for PELD according to HD with(More)
OBJECTIVE Sacral insufficiency fracture (SIF) contributes to severe low back pain. Prolonged immobilization resulting from SIF can cause significant complications in the elderly. Sacroplasty, a treatment similar to vertebroplasty, has recently been introduced for providing pain relief in SIF. The purpose of this study is to investigate the clinical(More)
OBJECTIVE Endoscopic foraminoplasty facilitates the engagement of the working cannula via the intervertebral foramen, allowing cannula access near the herniated disc (HD) for the successful application of percutaneous endoscopic lumbar discectomy (PELD). The purpose of this study was to evaluate the efficacy of foraminoplasty for HD and propose applicable(More)
