A prospective study of femoral shaft fractures in children under the age of 14 years has been carried out in 71 patients who were reviewed both clinically and radiographically at yearly intervals. The processing of data has been carried out by univariate and multivariate analysis. Femoral overgrowth (F.O.) averaged 8.63 mm (range 1-21 mm), and was found to be influenced by age (greater overgrowth in children between 3 and 9 years), the initial displacement of the fracture (greater overgrowth in severely displaced fractures), and overriding of the fragments at the time of healing (the greater the overriding the lesser the overgrowth). Consideration of these factors allowed overgrowth to be predicted from the time of fracture. Overgrowth occurred in all children over 2 years of age, and took place mainly during the first year after the fracture. It continued, although to a lesser extent, during the second year, and for as long as the fifth year in 27%. After this time the growth rate of both femurs was equal in all the children. Ipsilateral tibial overgrowth was present in only 60% of the children and averaged 1.05 mm (1-5 mm).
对71例14岁以下儿童股骨干骨折患者进行了一项前瞻性研究，这些患者每年接受临床和影像学检查。数据处理采用单因素和多因素分析。股骨过度生长（F.O.）平均为8.63毫米（范围1 - 21毫米），发现其受年龄（3至9岁儿童过度生长较多）、骨折初始移位（严重移位骨折过度生长较多）以及愈合时骨折碎片的重叠情况（重叠越多，过度生长越少）影响。考虑这些因素后，可以从骨折时预测过度生长情况。2岁以上儿童均出现过度生长，主要发生在骨折后的第一年。在第二年仍会持续，但程度较轻，27%的儿童会持续到第五年。此后，所有儿童两侧股骨的生长速度相等。仅60%的儿童出现同侧胫骨过度生长，平均为1.05毫米（1 - 5毫米）。
