A total of 203 profile countings were performed on 68 fractures of the tibial shaft, which included 25 normally healing cases, 37 cases of delayed union, and six cases of non-union. The measurements were performed on the 1st and the 7th day after the injection of strontium. In 27 cases the fracture received 2-3 strontium injections with associated profile counting at different stages of the healing process. The cases of normally healing fractures and delayed union showed differences in the average strontium uptake. However, these differences were not distinct enough to enable classification of individual fractures into groups. In cases requiring bone grafting, the transplant was found to accelerate metabolism and increase the accretion of strontium at the site of the fracture. The investigation shows that the real value of strontium profile counting lies in its ability to give information about the osteogenetic activity of the bone, which is a necessary prerequisite for the healing of the fracture.
对68例胫骨干骨折进行了总共203次轮廓计数，其中包括25例正常愈合病例、37例延迟愈合病例和6例不愈合病例。测量在注射锶后的第1天和第7天进行。27例骨折在愈合过程的不同阶段接受了2 - 3次锶注射及相关的轮廓计数。正常愈合骨折和延迟愈合病例在平均锶摄取量上存在差异。然而，这些差异不够明显，无法将个体骨折分类。在需要植骨的病例中，发现移植骨能加速代谢并增加骨折部位锶的积聚。研究表明，锶轮廓计数的实际价值在于其能够提供有关骨成骨活性的信息，这是骨折愈合的必要前提。
