Abstract：
Limping refers to an asymmetrical gait that deviates from the typical gait pattern expected for a child of a certain age. In most children, limping is caused by a mild, self-limiting event, such as a contusion, strain, or sprain. However, a child\'s limping is always a pathological finding that poses a particular diagnostic challenge and necessitates a thorough assessment. The pediatrician must weigh a wide range of acute and chronic potential causes of a non-traumatic limp, including infection, neoplasia, and chronic inflammatory disorders. A thorough history and clinical examination will help us arrive at the correct diagnosis. Understanding the typical gait is essential to recognizing and correctly interpreting the disordered one. The examination of child limping involves using a variety of diagnostic methods. Efficient and cost-effective diagnosis and treatment of the underlying condition requires a systematic approach. This review provides the pediatric rheumatologist perspective and approach for evaluating non-traumatic limp in children, with a focus on the use of point-of-care (PoC) musculoskeletal ultrasound (MSUS) as a crucial tool in daily practice.
摘要：
跛行指的是不对称的步态,其偏离对于一定年龄的儿童预期的典型步态模式。在大多数孩子中，跛行是由轻微的，自限事件,比如挫伤,应变，或扭伤。然而,一个孩子的一瘸一拐总是一个病理发现，提出了一个特殊的诊断挑战，需要一个彻底的评估。儿科医生必须权衡各种非创伤性跛行的急性和慢性潜在原因，包括感染,瘤形成,和慢性炎症性疾病。全面的病史和临床检查将帮助我们得出正确的诊断。理解典型的步态对于识别和正确解释无序的步态至关重要。儿童跛行的检查涉及使用各种诊断方法。有效且具有成本效益的诊断和治疗基础疾病需要系统的方法。这篇综述提供了小儿风湿病学家评估儿童非创伤性跛行的观点和方法。重点是使用即时护理（PoC）肌肉骨骼超声（MSUS）作为日常实践中的关键工具。
