Between 1993 and 1998, 332 I-BII (Insall Burstein II) prostheses were implanted in our department. We studied 5 cases of tibial polyethylene spine fractures. The fractures occurred 3 to 5 years following the surgery. All cases with fractures had mild medial laxity that was noted on follow-up of 2 to 3 years following arthroplasty. One also developed mild hyperextension. All the patients had a revision surgery. In 2 cases, the polyethylene was changed to a thicker one, together with medial reinforcement. Three cases were revised to a rotating hinge prosthesis.
1993年至1998年间，我们科室植入了332个I-BII（英萨尔·伯斯坦二世）假体。我们研究了5例胫骨聚乙烯脊柱骨折病例。骨折发生在手术后3至5年。所有骨折病例在关节置换术后2至3年的随访中均发现有轻度内侧松弛。其中1例还出现了轻度过伸。所有患者均接受了翻修手术。2例患者将聚乙烯换成了更厚的，并进行了内侧加固。3例患者翻修为旋转铰链假体。
