The distribution of hyaline cartilage in the sagittal plane of the normal human femoral head was examined. 28 specimens from persons aged 10 to 68 years subject to post-mortem examination in a teaching hospital were anatomically orientated and x-rayed in a lateromedial projection. An optical technique was used to measure the cartilage thickness from the x-ray films thus produced. Measurements were made with a sensitivity of +/- 0-01 mm using a metrological projector. 11 defined sites on each femoral head were surveyed to give the distribution of cartilage thickness. The greatest thickness was identified anterior to the zenith. Between the ages of 20 and 45 years the thickness of this zone increased with age. The thickness of femoral head cartilage was not evidently related to femoral head diameter, femur length, or body weight.
对正常人体股骨头矢状面透明软骨的分布进行了研究。选取了28例年龄在10至68岁之间、在教学医院接受尸检的标本，进行解剖定位，并拍摄后内侧位X线片。采用光学技术从所拍摄的X线片上测量软骨厚度。使用计量投影仪进行测量，灵敏度为±0.01毫米。对每个股骨头的11个特定部位进行测量，以得出软骨厚度的分布情况。发现最高点前方的软骨厚度最大。在20至45岁之间，该区域的厚度随年龄增长而增加。股骨头软骨厚度与股骨头直径、股骨长度或体重无明显关联。
