儿童骨龄评定与生长预测指导下肢不等长治疗的研究进展

Research advances in the treatment of leg length discrepancy guided by bone age assessment and growth prediction in children

下肢不等长(leg length discrepancy)是一种由常见骨科疾病导致的症状。通常小于1 cm的LLD临床表现并不显著,可无需治疗,而大于1 cm的LLD可能导致步态异常和脊柱畸形,因此需要进行干预。LLD患者的诊疗流程包括骨龄测定、生长预测以及治疗方式的选择。目前临床上存在多种骨龄评定与生长预测的方法,各有其优点与局限性。本文就骨龄测定方法、生长预测法和LLD治疗三个方面的研究进展进行综述。

Leg length discrepancy(LLD)is a frequent symptom of common orthopedic diseases.The clinical manifestation of LLD smaller than 1 cm is insignificant so that there is no need for intervention.However,LLD larger than 1 cm leading to abnormal gait and spinal deformity should be treated properly.The management process of LLD patients includes bone age determination,growth prediction and selecting treatment options.Currently many methods are available for bone age assessment and growth prediction.Yet each modality has its own advantages and limitations.This review summarized the latest researches of bone age determination,growth prediction and proper treatment of LLD.
