Traumatic anterolateral dislocation of the fibular head is an uncommon sports injury which is easily overlooked. Seventeen cases have been collected during private practice over the years. The typical mechanism of injury is a fall on the affected flexed knee with the leg adducted under the body and the ankle inverted. On physical examination there is an obvious bony prominence laterally of the fibular head and varying disability with activities; there is no significant effusion or signs of internal knee derangement or instability. Comparison identical radiographic views are necessary to confirm the diagnosis: on the anteroposterior view the fibular head is displaced laterally and the proximal interosseous space is widened; on the lateral view there is a greater overlap of the fibula on the tibia on the affected side. Peroneal nerve and ankle injuries can occur concomitantly with anterolateral proximal tibiofibular dislocation. Treatment options are closed or open reduction acutely and local strapping or fibular head resection for chronic cases based upon time of presentation and disability.
腓骨头创伤性前外侧脱位是一种罕见的运动损伤，很容易被忽视。多年来在私人诊所收集了17例病例。典型的损伤机制是患侧屈膝跌倒，下肢内收于身体下方且踝关节内翻。体格检查时，腓骨头外侧有明显的骨性突出，活动时有不同程度的功能障碍；无明显积液或膝关节内部紊乱或不稳定的体征。需要对比相同的X线片来确诊：前后位片上腓骨头向外侧移位，近端骨间隙增宽；侧位片上患侧腓骨在胫骨上的重叠更多。腓骨头前外侧脱位可能同时伴有腓总神经和踝关节损伤。治疗方案根据就诊时间和功能障碍情况，急性期可选择闭合或切开复位，慢性病例可选择局部绑扎或腓骨头切除术。
