The Schnöllner operation for reduction of spondylolisthesis was performed through a transversal incision. After removal of the disc, two pedunculus screws with two different threads are inserted. Over these screws the reduction is performed against a slotted sacral plate. The operations were performed at the following levels: 48 at L5-S1, seven at L4-L5, and two at both levels. 70.8% of the patients had preoperative lumboischialgia, 23.3% lumbalgia. Postoperatively, 92.1% were without pain. Twenty-seven patients had preoperative sensory disturbances, while only five had such disorders five years after operation. New sensory disturbances occurred after operation in 11 patients, seven of these persisted. Before operation, 27 patients had pareses of the foot and toe extensors; after operation, ten of them. Paresis occurred in 12 cases, of which three persisted. In 13 cases the reposition was complete, in 17 cases the displacement after operation ranged from 11% to 30%. The lumbosacral angle was markedly diminished.
施诺尔纳（Schnöllner）复位腰椎滑脱手术通过横向切口进行。切除椎间盘后，插入两枚不同螺纹的椎弓根螺钉。在这些螺钉上方，对着开槽的骶骨板进行复位。手术在以下节段进行：L5 - S1节段48例，L4 - L5节段7例，两个节段均有手术的2例。70.8%的患者术前有腰腿痛，23.3%有腰痛。术后，92.1%的患者无痛。27例患者术前有感觉障碍，而术后五年只有5例有此类障碍。术后有11例出现新的感觉障碍，其中7例持续存在。术前，27例患者有足趾伸肌轻瘫；术后，其中10例仍有轻瘫。有12例出现轻瘫，其中3例持续存在。13例复位完全，17例术后移位范围为11%至30%。腰骶角明显减小。
