INTRODUCTION
Iatrogenic patellar fracture is reported as a complication of patella procedures, such as medial patellofemoral ligament reconstruction, reconstruction of the anterior cruciate ligament of the knee using bone-patellar tendon-bone technique, and resurfacing the patella in total knee arthroplasty.
CASE PRESENTATION
A 65-year-old lady with right patella fracture was treated with open reduction and cerclage wiring. An iatrogenic split fracture was noted during tension of the cerclage wire and was successfully managed by screw fixation of the split fracture.
CONCLUSIONS
Split fracture is a rare complication of circumferential cerclage wiring of patellar fracture. The surgeon should be aware of the contributing factors in order to avoid this complication.
引言
医源性髌骨骨折被报道为髌骨手术的一种并发症，如内侧髌股韧带重建、采用骨-髌腱-骨技术重建膝关节前交叉韧带以及在全膝关节置换术中对髌骨进行表面置换。
病例报告
一名65岁的右髌骨骨折女性接受了切开复位和环扎钢丝固定治疗。在环扎钢丝张力过程中发现了医源性劈裂骨折，并通过对劈裂骨折进行螺钉固定成功处理。
结论
劈裂骨折是髌骨骨折环扎钢丝固定的一种罕见并发症。外科医生应了解相关影响因素以避免这种并发症。
