Ⅱ型:假体柄所在部位骨折
Ⅲ型:假体以远部位骨折
Ⅳ型:胫骨结节骨折
各型中分别含A、B、C亚型“A型:假体固定良好;B型:假体松动;C型:术中骨折”[1] Felix NA, Stuart MJ, Hanssen AD (1997) Periprostheticfractures of the tibia associated with total knee arthroplasty. Clin OrthopRelat Res 345:113–124处理原则危险因素
表面重修(最主要) 创伤
髌股关节对线不良
截骨过多或不对称髌骨假体周围骨折
Goldberg分型[1]Ⅰ型:髌韧带完好,未累及关节面
Ⅱ型:髌韧带损伤,或累及关节面
Ⅲ型:髌骨下极骨折,髌韧带损伤Ⅲa,髌韧带完好Ⅲb
Ⅳ型:髌骨骨折脱位[1] Goldberg VM,Figgie HE 3rd,Inglis AE,etal. Patellar fracture type and prognosis in condylar total knee arthroplasty.Clin Orthop. 1988;236:115-122.备注:主要依据伸膝装置的完整性、髌骨假体的固定情况和骨折的解剖部位将髌骨假体周围骨折分为4型治疗原则手术效果不稳定,存在争议[1]
未累及关节面,髌韧带完好(I,IIIa)——保守治疗
累及关节面或髌韧带受累(II,IIIb,IV)——ORIF
