2、 at presentation is 2 years.在美國，未成年人急診就診中牽拉肘的發(fā)生率大約在2.7/1000.相關(guān)報道(bodo)的中位年齡為2歲。The injury is unique to infants and young children because the radial head is lessbulbous than it is in older persons and may easily become displaced.牽拉肘特別常見于嬰幼兒和青少年，因為幼兒的橈骨頭還未發(fā)育像成人那樣的圓球狀橈骨頭，所以很容易移位。Reduction of a pulled

3、elbow is a safe procedure that can be performed in the outpatient setting.復(fù)位牽拉肘是相對安全的操作，完全可以在門診進行。The annular ligament encircles the neck of the radius and holds it tightly in placeagainst the ulna), thereby maintaining the position of the proximal radiusin relation to the ulna and the capitellum of

4、 the distal humerus while allowing180-degree rotation.環(huán)狀韌帶包繞橈骨頸使其緊鄰尺骨，從而維持橈骨與毗鄰尺骨以及肱骨遠端肱骨小頭的相對位置，同時可以完成180旋轉(zhuǎn)。When there is forceful longitudinal traction, such as when a child is pulled or lifted by the arm, the radial head is pulled underneath the annular ligament.在強大的縱向（軸向）牽拉下，比如提拉幼兒手臂或用手臂引體向上時，橈骨

10、raindications to performing a reduction are few and are usually easilyRecognized.復(fù)位的禁忌征很少且容易(rngy)鑒別。If a child has a history and physical examination that are consistentwith fracture, such as deformity, swelling, or bruising of the elbow or a history ofa fall onto the arm from a substantial height,

11、 then a radiograph should be obtainedto evaluate for fracture.如果孩子的病史或體格檢查與骨折吻合，比如畸形，腫脹或肘關(guān)節(jié)挫傷或有高處摔落手臂著地的外傷史，則應(yīng)行影像學(xué)檢查來判斷是否骨折。If the radiograph does not reveal fracture or effusion, thenreduction may be considered.如果影像學(xué)檢查未發(fā)現(xiàn)骨折或突出，則可以考慮手法復(fù)位。第八頁，共二十頁。橈骨小頭半脫位橈骨小頭半脫位In one study, reduction was achieved on
