The article demonstrates the diagnostic value of the direct x-ray enlargement technique, taking a group of 11 patients with osteochondrosis dissecans of a femoral condylus as an example. The method is unsuitable as a diagnostic screening method, since the informative content of the enlarged roentgenograph, is greater in a defined area only, and since the additional exposure burden should not be overlooked, especially in the patients in question, who are mostly relatively young. However, the direct radiological enlargement technique is well suited for postoperative follow-up, since it is only with the help of visualization of the increasing trabecular bone bridges between femoral condylus and dissecate, that the process of incorporation can be visualized and hence also judged in respect of its success.
本文以一组11例股骨髁剥脱性骨软骨炎患者为例，展示了直接X线放大技术的诊断价值。该方法不适用于诊断性筛查，因为放大后的X线片仅在特定区域具有更高的信息量，且不应忽视额外的辐射负担，尤其是对于这些大多相对年轻的患者。然而，直接放射学放大技术非常适合术后随访，因为只有借助可视化股骨髁与剥脱骨块之间不断增加的小梁骨桥，才能观察到骨块融合的过程，从而判断其成功与否。
