Twenty-two necrotic femoral heads in young adults were radiologically followed-up after grafting with vascularized bone by comparing the preoperative and the postoperative state of the hip joint. Three parameters were observed and followed; the flattening of the femoral head; the degree of osteoarthrosis of the joint; and the degree of incorporation of the graft into the recipient bone. The results, expressed by index figures, showed that the femoral head flattened during the first two years postoperatively; that the maximal incorporation occurred during the same period of time; and that the appearance of postoperative osteoarthrosis was slow during the first year and increased subsequently. This numerical characterization of radiological findings allows systematic individual analysis after revascularization of the femoral head with bone grafts. It is also suited for comparisons between patients, between series of patients and of various treatment techniques. Furthermore, this quantification provides a numerical index that seems to correlate with the outcome of the treated hip joint.
通过比较髋关节术前和术后状态，对22例年轻成人坏死股骨头进行带血管骨移植后的放射学随访。观察并跟踪了三个参数：股骨头的扁平程度；关节骨关节炎的程度；以及移植物与受体骨的融合程度。以指数数字表示的结果表明，股骨头在术后头两年变扁平；最大融合发生在同一时期；术后骨关节炎在第一年出现缓慢，随后增加。这种放射学结果的数值表征允许在股骨头带骨移植再血管化后进行系统的个体分析。它也适用于患者之间、患者系列之间以及各种治疗技术之间的比较。此外，这种量化提供了一个似乎与治疗后髋关节结果相关的数值指标。
