| 【Abstract】 Objectives: To evaluate and compare the safety and effectiveness of ultrasonic bone curette(UBC) versus traditional tools(TT) in degenerative lumbar scoliosis(DLS) decompression and osteotomy. Methods: From February 2008 to December 2016, 54 DLS patients with age no younger than 45 years underwent posterior decompression. Ponte osteotomy, long segment(more than or equal to five levels) instrumented and fusion by UBC or TT were included as UBC group(28 patients) or TT group(26 patients) in our hospital. Instrumental complications, neurological deterioration at discharge, operation time, evaluated blood loss (EBL), EBL/vertebra fused and cell saver transfused were compared between the two groups. Results: The numbers of laminectomies, Ponte osteotomies and discectomies in UBC group were more than those of TT group(P<0.05). Instrument related complications and neurological function at discharge showed no significant difference between UBC group and TT group(P>0.05). The EBL, EBL/vertebra fused and cell saver transfused in UBC group were less than those in TT group(834.0±354.4ml vs 1467.3±804.9ml, P=0.002; 120.8±57.2ml vs 191.4±88.4ml, P=0.003; 342.3±179.9ml vs 552.2±295.2ml, P=0.003). Conclusions: The UBC is more effective and safe for posterior decompression, Ponte osteotomy, long segment instrumented and fusion in DLS patients. When compared to TT, the usage of UBC is relatively more effective with significant less intraoperative blood loss, and the safety of UBC is at least not less. |
