摘要
作者对61例股骨颈骨折后的股骨头进行了组织学检查,发现52％的股骨头有不同时相的骨髓腔内出血(简称IH)或含铁血黄素沉着。出血灶位于坏死区内或与坏死骨相间。坏死越严重,IH的发生率越高。统计学分析表明,不同坏死分级的IH发生率之间的差别有高度显著性(p<0.01)。认为严重的IH可阻断局部骨髓和骨小梁的血液供应,导致或加重股骨头缺血坏死。并讨论了股骨颈骨折治疗过程中防止股骨头内再出血的方法及其临床意义。
61 femoral heads after femoral neck fracture were examined hislologically. There were hemosiderin or multiphase intramedullary haem-orrhage(IH)in 52% of the femoral heads. A statistical analysis showed significant differences in the incidence of IH between the groups with different grades of necrosis(P<0. 01). Above phenomena indicate that there is certain correlation between IH and avascular necrosis. Serious IH may interrupt local blood supply to both bone marrow and trabeculae besides a damage of the retinacular vessels,and is of definite effect on initiation and aggravation of avascular necrosis.
