Traumatic Hip Dislocation
外傷性髖關節脫臼
摘要
在台灣，外傷性髖關節脫臼已成為骨科急診常見之疾病。分析75例(男60仃，女15例)病患，年齡由3歲到76歲不等，52%為活動範圍較大的20至40歲，86.8%因車禍所致，其中四份之三是摩多車騎士。以脫臼方位來分，後位性佔56例；中位性17例；前位性2例。而後位性依受傷程度不同，細分成5型。經追蹤治療後發現，受傷的嚴重度或脫臼型式以及脫臼持續時間與日後股骨頭壞死或骨性髖關節炎有莫大關連，小心迅速的復位，尤其在受傷後12小時以內完成，可以帶來較滿意的結果。髖臼的電腦斷層掃描，是評估關節面破壞程度及是否完全復位的好方法。同時將脫臼皆型，有助於治療的計劃及預估未來的結果。在穩定型脫臼復位後，平均牽引18天，但非穩定型者，則多需20天為荷。雖然手術使關節面盡可能完美，但並不能減少外傷性骨性關節炎，更沒有減少股骨頭壞死的發生，手術僅提供骨折的復位使日後做髖關節重整手術時有較軏整的骨質。

Traumatic hip dislocation (THD) is not a rare orthopaedic emergency for it is encountered daily in Taiwan. Seventy-five cases (60 males and 15 females)were analysed, the subjects ranged in age from three to 76 years and 52% fell in the active age group from 20-40 years old. 86.8% were due to traffic accidents, and three quarters of them were the result of high-speed motorcycle accidents. There were 56 posterior dislocations, 17 central dislocations and 2 anterial dishlocations. The complications and morbidity, particularly the cases with femoral head avascular nerosis or dislocation, and the duration of dislocation. Prompt, and gently reduction within 12 hours remains the cornerstone of successful therapy. Secondly, the typing of the dislocation provides guideline for planning the recuction and the duration of traction immobilization after the reduction. Stable dislocations need an average of 18 days of traction, while unstable types ned another 20 days.
