摘要
目的 :关于骺—干骺动脉在骨折愈合中的作用 ,资料较少 ,有必要研究。方法 :本研究用家兔 2 4只 ,4只用于观察正常骺端皮质血管。其余制作骨折模型并于骨折后 38、18、2 8、42 d分别处死 ,观察骺—干骺端皮质微血管的变化。结果 :早期 (3～ 8d)骺端皮质微血管扩张明显 ,中期 (8～ 2 8d)血管扩张及血管相对密度达到最高峰 ,后期 ,血管变细 ,密度降低 ,但仍然比正常组高。结论
Objective:The effects of epiphyseal-metaphyseal were know a little after fracture.Methods:The experiment involved 24 rabbits.4 rabbits were killed and performed ink perfusion on artery of femur to survey the blood vessels of compacta of epiphysis and metaphysis,the orthers received simulated fracture on tibia and were sacrified respectively in 3,8,18,28,42 days after operation to survey recorstruction of vessels of compacta of epiphysis and metaphysis.Results:The vascular changes were as follows,in early stage (3 days),the blood vessels were quite distended,in mid-stage (8-28 days),the density of vessels rose to the highest,and later stage,the density of vessels decreased but were higher than density of normal group.Conclusions:It was snggested that the blood vessels of epiphysis and metaphysis were very important in fracture healing.
