股骨头坏死，不错的文献

[upload=1] Abstract
Osteonecrosis of the femoral head is a disabling clinical entity affecting young adults that usually leads to destruction of the hip joint.A high
index of suspicion is necessary for the diagnosis due to the insidious onset of the bone infarcts and the lack of specific clinical signs at the early
stages.Many etiology-associated factors have been identified reducing thus the number of idiopathic cases.A number of joint salvaging treatment
options are available if early diagnosis can be achieved.MR imaging has been proved to be a highly accurate method both for early diagnosis and
for staging of the disease.Replacement of the hip joint is the last resort for pain relief and function,although non-desirable because of the young
age of the affected population.

摘要
股骨头坏死是一种临床致残疾患，好发于年轻患者，通常会导致髋关节破坏。由于此病发病隐匿，早期缺乏骨坏死和特异性临床症状，因此对此病的诊断主要基于早期的高度怀疑。目前导致该病的许多病因学相关因素已经确定，因此特发性股骨头坏死的数量有所减少。如果该病得到早期诊断，临床有多种挽救方案可供选择。MRI检查已被证明是一个非常准确的方法，可以提供早期诊断和疾病分期。髋关节置换术是最后的手段，主要是为了减轻疼痛和功能障碍，尽管罹患该病得主要人群是青年患者，接受关节置换并非患者理想初衷。
