SURGICAL GOAL: Surgical treatment of dynamic lumbar spinal stenosis and discogenic/arthrogenic low back pain with a new percutaneous interspinous spacer as a therapeutic alternative to more invasive standard procedures.
Central, lateral and foraminal dynamic lumbar spinal stenosis. Discogenic and arthrogenic (facet osteoarthritis) low back pain. Symptomatic, segmental hyperlordosis. Disc degeneration with dynamic (reducible) retrolisthesis. Interspinous pain ('Kissing-Spines').
Osteoporosis. Conus-/Cauda-syndrome. Structural spinal stenosis. Spondylolisthesis (degenerative and/or isthmic). Deformities. Previous posterior operation in index segment.
Percutaneous, minimally invasive implantation of an interspinous spacer (InSpace ™, Synthes, Oberdorf, Switzerland).
Early unrestricted mobilization.
Good early results (after 2 year follow-up) in 42 patients with 76% subjective patient satisfaction rate. No approach related complications. Avoidance of the more invasive alternative procedure (decompression, fusion, total disc replacement) in 76.2% of the patients.
手术目标:采用新型经皮棘突间间隔器对动力性腰椎管狭窄症和椎间盘源性/关节源性下腰痛进行手术治疗,作为更具侵入性的标准手术的一种治疗选择。
中央型、侧方型和椎间孔型动力性腰椎管狭窄症。椎间盘源性和关节源性(小关节骨关节炎)下腰痛。症状性节段性腰椎前凸。伴有动力性(可复位)椎体滑脱的椎间盘退变。棘突间疼痛(“亲吻棘突”)。
骨质疏松症。圆锥/马尾综合征。结构性椎管狭窄。椎体滑脱(退行性和/或峡部裂性)。脊柱畸形。索引节段既往有后路手术史。
经皮微创植入棘突间间隔器(InSpace™,辛迪思,瑞士奥伯多夫)。
早期无限制活动。
42例患者早期效果良好(随访2年),患者主观满意率达76%。无与手术入路相关的并发症。76.2%的患者避免了更具侵入性的替代手术(减压、融合、全椎间盘置换)。
