髖關節是人體最大且重要的關節,穩定性極佳,主要功能為支撐身體的重量及維持正常的步態。若髖部疼痛便會影響到活動功能。引起髖部疼痛的原因很多,疾病史及理學檢查對鑑別診斷相當重要。但年輕成人髖部疼痛的表現常不明顯,病史及檢查多為正常,其原因大多為局部髖關節或腰椎受傷所致。若排除常見疾病後,可能應考慮是否有下肢生物力學結構的問題,例如足內翻或外翻、腿長不等及肌肉無力等情況,因而造成髖部疼痛。本文提供年輕成人髖部疼痛的個案,以下肢生物力學的觀點,發現個案有足部過度旋前及腿長不等的問題,利用適當的矯正鞋墊矯正身體力學結構上的不平衡,不需依賴藥物便使病人症狀緩解,並可預防髖部疼痛的反覆發作。
The hip is the largest and most important joint in the human body, characterized by extremely good stability. The major functions of the hip joint are to support the body's weight and maintain normal gait. Hip pain, which may be caused by several reasons, affects the normal functioning of several activities. Although medical history and physical examination are important in differential diagnosis, they often present as normal because the symptoms of hip pain in young adults are not always obvious. The most common cause is local injury of the hip joint or lumbar spine. Ruling out common diseases of the hip joint, we considered biomechanical problems of the lower limb. For example, foot varus or valgus, discrepancy in leg length, or muscle weakness may also induce hip pain. This article presents the case report of a young adult with hip pain. Using biomechanic concepts, excessive pronation of the foot and discrepancy in leg length were found. Using suitable foot orthosis to correct the imbalance in body mechanics without the use of medication can relieve the symptoms of hip pain and prevent relapse.
