摘要

股骨頭壞死是一種常見到之疾病，它可以使病人行動困難，造成日常生活不便：磁振造影術對於股骨頭病變的偵測，非常敏感，可以診斷出早期之股骨頭壞死。本研究之目的在於對於患者一側有股骨頭壞死，我們利用磁振造影術，檢查其另一側之股骨頭，以便早日發現早期之股骨頭壞死。本研究收集自民國84年8月至86年7月，54例股骨頭壞死之病例。我們為病人忠、側及另側股關節作磁振造影術檢查。我們並紀錄病人是否有抽煙，飲酒之習慣，其患側疼痛之時間；兩側股骨頭之常規素片，磁振造影術之變化。結果顯示：在常規素片方面，無症狀一側之股骨頭，祇有10例（18.5%）可以從片子中看出病變：在磁振造影方面，則有29例（53.7%）可以從片子中看出訊號有變化。顯然的，磁振造影比常規素片敏感很多。因此我們建議當懷疑病人股，骨頭有壞死時，宜進行兩側之股骨頭磁振造影檢查，以便早日發現早期股骨頭壞死，造福病患。

Osteonecrosis is a common disease; it will lead to difficulty in walking, which decreases the patient s quality of life. Magnetic resonance (MR) imaging is a new and sensitive modality for the early detection of osteonecrosis of the hip. Our study attempted determine the incidence and extent of osteonecrosis in the asymptom atic hip when the patient had osteonecrosis in the other hip joint. We collected 54 cases of proven osteonecrosis of the hip for this study. All patients underwent bilateral MR imaging of the hips. Radiographs and MR images were assembled and assessed for changes in the asymptomatic hip joint. Our results showed that hip radiography detected bony changes in 18.5% cases, while MR imaging showed change of signal intensity in 53.7% of the cases. Obviously, MR imaging is more sensitive than radiographs. The incidence of bilateral involvement of osteonecrosis in the hip joints is relatively high. We suggest MR imaging of both hip joints for early detection of osteonecrosis.
