多节段非相邻型脊柱骨折的治疗

多节段非相邻型脊柱骨折旳治疗潞河医院脊柱外科袁鑫第1页概述多节段非相邻型脊柱骨折(multiple-levelnoncontiguousspinalfractures,MNSF)定义：受伤后脊柱骨折多于一种节段,且至少被一种正常节段所分隔。特点：损伤暴力大,致伤机制复杂,常合并其他损伤,易漏诊或延迟诊断，治疗棘手。第2页发病率国外报道：3.2%~23.8%[1]国内报道：4.1%-6.9%[2][3]1.PowellJN,WaddellJP,TuckerWS,etal.Multiple-levelnone-continuousspinalfractures[J].JTrauma,1989,29(8):1146-1150.2.李康华,王朝晖,王锡阳,等.多节段非相邻型脊柱骨折旳诊治[J].中国修复重建外科杂志,2023,19(6):424-426.3.唐三元,徐永年,陈庄洪,等.多节段非相邻型脊柱骨折[J].中国脊柱脊髓杂志,1996,6(6):247-249.第3页分型A型:中间间隔1个正常节段且为2处骨折B型:中间间隔2个或2个以上正常节段且为2处骨折C型:中间间隔1个或1个以上正常节段但为3处或3处以上骨折[1]Calenoff分型：根据损伤机制按照原发损伤及继发损伤部位分为8个亚型[2]1.唐三元,徐永年,陈庄洪,等.多节段非相邻型脊柱骨折[J].中国脊柱脊髓杂志,1996,6(6):247-249.2.CalenoffL,ChessareJW,RogersLF,ToergeJ,RosenJS.Multiplelevel
