Flattening of the epiphysis of the long bones is seen in several bone dysplasias. It is the hallmark of multiple epiphyseal dysplasia and is an important sign in the diagnosis of spondyloepiphyseal dysplasias, diastrophic dysplasia, and pseudoachondroplastic dysplasia. The goal of this study was to determine norms for the height of the distal femoral epiphysis and to apply these standards to patients with bone dysplasias. Ratios of the distal femoral epiphysis height to both the distal femoral metaphysis width and the distal femoral epiphysis width were obtained from 640 radiographs of healthy children of different ages. Application of these standards to 41 patients with the bone dysplasias mentioned above proved useful in ascertaining decreased height of the distal femoral epiphysis. These standards are of particular value in subtle or early cases in which the thinning of the epiphysis may not be apparent upon simple observation. Obtaining three simple measurements from the anteroposterior knee radiographs allows determination of the presence or absence of flattening of the epiphysis.
在多种骨发育异常中可见长骨骨骺变平。它是多发性骨骺发育异常的标志，也是诊断脊椎骨骺发育异常、畸形性发育异常和假性软骨发育异常的重要体征。本研究的目的是确定股骨远端骨骺高度的标准，并将这些标准应用于骨发育异常患者。从640张不同年龄健康儿童的X线片上获得了股骨远端骨骺高度与股骨远端干骺端宽度以及股骨远端骨骺宽度的比值。将这些标准应用于41例上述骨发育异常患者，结果证明有助于确定股骨远端骨骺高度降低。这些标准在单纯观察时骨骺变薄可能不明显的细微或早期病例中具有特殊价值。通过对膝关节前后位X线片进行三项简单测量，可确定骨骺是否变平。
