目的:通过带螺纹内固定贯穿股骨头骺板的实验研究,分析带螺纹内固定是否会造成生长抑制及其关系。
方法:新西兰兔40只,分为4组,每组10只,螺纹针穿透骺板并留置其内造成骺板损伤,通过螺纹针数量增减改变损伤面积,A组为空白对照组,B组为损伤骺板面积的4%,C组为损伤骺板面积的6%,D组为损伤骺板面积的8%.用X线机对4组实验对象进行定期摄片观察,术后2周拆内固定,继续定期摄片,判断骺板有无早闭等并发症。
结果:各实验组与对照组在实验观察期间,股骨颈长度、直径,股骨头直径、骺板闭合时间差异均无统计学意义。股骨颈长度、直径,股骨头直径生长速度先快后慢,在骺板将要闭合时最慢。
结论:兔股骨头骺板损伤面积在8%以下是安全的,不会对股骨颈发育起到抑制作用。螺纹针可以用于兔骺板部位,未发现该固定方法对骺板的发育起到抑制作用。 |

| Experimental study on internal fixation with screws through femoral epiphyseal plate |

Abstract:
Objective:To explore the effect of internal fixation with screw through femoral epiphyseal plate on growth inhibition via an experimental study.
Methods:Forty New Zealand rabbits were randomly divided into 4 groups and 10 rabbits in each group. Epiphyseal plate was injured by penetrating of screws,and the size of damage area was controlled by changing the number of threads. Group A:blank group;group B:injury area accounted for 4% of the epiphyseal plate;group C:injury area accounted for 6%;group D:injury area accounted for 8%. The internal fixation was removed after 2 weeks,and the results were observed with X-ray film for 4 groups to judge the complications such as early closure of epiphyseal.
Results:In each group,there were no statistical differences in the length of the femoral neck,the diameter of femoral neck,the diameter of the femoral head,and the epiphyseal plate closure time. The growth speed of the length and diameter of the femoral neck,as well as the diameter of femoral head,were quicker on the early phase,and the speed was slowest when the epiphyseal plate was being closed.
Conclusion:The injury area of epiphyseal plate under 8% is safe for its growth. Because no evidences demonstrate the growth inhibition of epiphyseal plate,the screws can be used for rabbit epiphyseal plates. |
