股骨是大腿骨，股骨的末端形成球狀，與髖關節相連接。骨頭壞死多因失去血液供養，壞死的部位全身都有可能，若在股骨頭的部位稱為股骨頭壞死( Avascular necrosis of femoral head )。血液供養全身細胞，如果發生循環中斷或停止，則會造成該器官部位受損，心臟例如心肌梗塞、腦部例如中風等。發生在股骨頭，則會造成負重結構塌陷，軟骨垮下，導致髖關節持續發炎、整個髖關節退行性病變。初期症狀多為髖關節卡卡很緊，或腹股溝區疼痛、或走路跛行，如果進一步不能盤腿或無法走路時，才驚覺事態嚴重。

然而，股骨頭壞死的進程很快，沒有明顯警示，很多患者來找醫師時已經出現大範圍壞死，卻被當成腰痛或膝蓋痛處理。筆者建議最好先做理學檢查，而且二側都檢查，因為此病雙側髖關節均罹病的機率很高。如果是初期，X光片是看不太出來的，要用CT電腦斷層或MRI核磁造影。股骨頭壞死原因可能為外傷性或非外傷性。外傷的話，骨頭斷掉或脫臼造成血液與養分輸送停頓；若與受傷無關的話，機轉未明，也可能是長期服用類固醇導致。

Born Again with the Acupuncture Treatment for Avascular Necrosis of the Femoral Head

The femurs are a pair of thigh bones; the head of the femur takes the shape of a ball and articulates with the hip joints. Most avascular necrosis (AVN) is caused by the loss of blood supply to the bone. The death of bone tissue may occur in any part of the body. When it occurs in the head of the femur, it's called AVN of the femoral head. The blood supplies oxygen to the cells across the human body. If the supply is disrupted or stopped, the organs and parts where the disruption takes place will be damaged. For instance, when the disruption takes place in the heart, myocardial infarction will strike, and if it occurs in the brain, a stroke will result. If it occurs in the femoral head, the weight-bearing structure will collapse and the soft bones will break down, leading to constant inflammation and degenerative lesions in the hip joint. The symptoms in the preliminary phase include the locking of – and tightness in – the hip joints, pain in the groin, and limping when walking. When patients are not able to sit with crossed legs or walk, often the condition is already very severe.
