Objective Quantification of the severity of congenital clubfoot is essential for its re-search and treatment. Up to date, no scoring system is available for hind limb bud development. In this study,a scoring system was established based on a murine model Methods Sixty female Wistar rats weighing 220~250 g were randomized into the six control groups and six experimental groups. Vaginal sperm plug detection day was considered to be day 0 of gestation. Hind limb buds from fetuses of E13, 14, 15,16,17 and 18 days were removed and processed. Results Morphogenetic differentiation changes were detected in the experimental groups. According the new scoring system, clubfoot-like deformity was present in 80.9% of the experimental fetuses. We were able to quantify the extent morphogenetic diffcrentiation of the hind limb accordingly. Conclusions Congenital clubfoot deformities begin at early developmental stage and become exaggerated as the fetuses mature. The scoring system can quantify the extent of congenital clubfoot deformity and facilitate its management. 相似文献

颈椎由于创伤、肿瘤切除、畸形矫正等原因造成颈椎不稳定,需要重建颈椎的稳定性.既往使用侧块螺钉固定、钢丝脊突间固定、钩型钢板固定等固定技术,以上方法均固定颈椎的前柱加中柱或后柱,术后需要加用外固定才能保持其稳定性. 相似文献
