髋臼骨连接不正非常难以治疗,多年来,已经由全髋关节置换手术适应症。我们对待一个突出的髋臼的畸形愈合,20年前,使用一个关节内的支持,通过一个同种异体移植物对应于股骨头片段被冻存。这种扩展的放射学和临床结果后续非常引人注目,它激励我们现在这种原始的技术。
髋臼骨连接不正非常难治疗(
D先生。,aged 31, was hospitalised urgently in late June 1999, in a teaching hospital 300 km from his home, following a polytrauma sustained in a motorcycle accident. The initial workup revealed a left haemopneumothorax, a ruptured spleen, bilateral acetabulum fractures with intrapelvic protrusion on the right, a bifocal right femur fracture, and a diaphyseal left femoral fracture. A haemostatic splenectomy was carried out immediately and the haemopneumothorax drained. The femoral fractures were nailed 2 days later, but no surgery was carried out on the right acetabulum. The patient was transferred to our facility 5 weeks after sustaining the initial injuries, to be closer to family, presenting acetabular protrusion of the right femoral head (Figure
初始状态的髋臼的骨折。
病人接受手术在1999年8月5日,5周后初始事故。我们决定使用侧方法,同时访问两个髋臼的列。病人被放置在一个标准的操作表,在横向卧位,阴和腰骶的接触,和纯粹的横向切口,切除外侧长伽马钉植入的疤痕。这伤疤从髂骨15厘米以下的大转子。20厘米纵向开放提供完美的筋膜接触的转子的地区和臀中肌。由于钉子的存在,我们决定部分臀中肌横截,其转子插入2厘米以上,提升臀部肌肉,曾因3斯坦曼别针,钉入髂翼。臀小肌也沿着大转子disinserted,充分暴露前和髋关节的关节囊的上部分。后,有必要disinsert上层pelvitrochanteric肌腱,没有动人的股方肌。为了深入联合,我们进行了一次periacetabular关节切开术,紧随其后的是一个近端股骨颈的纵向切口沿轴,和disinsertion沿着转子间线前荚膜的皮瓣。这为我们提供了一个完美的两列视图以及关节腔。 Unfortunately, all attempts to reduce the fracture failed, as the fracture had consolidated at both the front and rear. When luxating the hip joint, we observed that the acetabular cavity was perfectly congruent with the femoral head and that simply pressing a compress deep into the acetabulum would restore this congruence. We therefore decided to replace this compress with a cryopreserved femoral head fragment from the bone bank, which we fitted to the bottom of the acetabulum and the femoral head, forming a self-stabilising intra-acetabular buttress (Figure

20多年后,病人仍然作为一个送货司机,咨询的左髋部疼痛,导致早期骨关节炎。右髋关节仍没有痛苦,和运动的范围如下:100°弯曲,扩展180°,内部旋转10°,外部旋转30°,绑架30°,内收10°。放射检查,没有可见的髋关节骨关节炎,和intra-acetabular贪污是完全集成(数据

髋臼的骨折畸形愈合后是相对常见的骨科或手术治疗。治疗是困难的,和缺乏公布的数据。治疗通常建议在过去的20年里已经全髋关节置换术(THA) [
在髋臼的畸形愈合intrapelvic突出,intra-acetabular支撑是一种可行的选择,因为它恢复股骨head-acetabulum一致。这与长期随访观察鼓励我们推广这种技术,特别是现代成像技术的使用允许容易识别的理想术前适应症。
