Calcaneal apophysitis is the most common cause of heel pain in children and adolescents. However, the relationship between skeletal maturity and heel pain in the specific youth cohort is unclear.
To clarify the relationship between the maturity stages of the calcaneal apophysis and heel pain in youth baseball players.
Cross-sectional study; Level of evidence, 3.
A total of 336 youth male baseball players participated in this study. Ultrasound scanning of the calcaneal apophysis was performed along the longitudinal line connecting the middle of the Achilles tendon, the middle of the calcaneus, and the second toe, between the proximal calcaneal edge and the medial calcaneal tubercle. The authors classified the maturity of the calcaneal apophysis into 5 stages, from nonpresence of the apophysis (stage 1) to complete fusion (stage 5). The diagnosis of heel pain was based on subjective report of feeling pain on the squeeze test. The relationship between the maturity stages and physical characteristics was investigated using 1-way analysis of variance or the Kruskal-Wallis test, and the relationship between the maturity stages and heel pain was investigated using the chi-square test.
Of the 336 players, 49 had heel pain, for a prevalence of 14.6%. Eighteen (5.4%) players had unilateral heel pain, and 31 (9.2%) players had bilateral heel pain. There were no significant differences in the maturity stages of the calcaneal apophysis between the players with no heel pain and those with heel pain. However, no players had heel pain during stage 5, when the calcaneus had completed its maturation.
The prevalence of heel pain was 14.6% in Japanese youth male baseball players. There was no relationship between the maturity stages of the calcaneal apophysis and heel pain. Heel pain that could be associated with calcaneal apophysitis did not occur during stage 5, when maturation of the calcaneal apophysis was complete.
跟骨骨骺炎是儿童和青少年足跟痛最常见的原因。然而，在特定青年人群中，骨骼成熟度与足跟痛之间的关系尚不清楚。
阐明青年棒球运动员跟骨骨骺成熟阶段与足跟痛之间的关系。
横断面研究；证据等级，3级。
共有336名青年男性棒球运动员参与本研究。沿连接跟腱中点、跟骨中点和第二趾的纵线，在跟骨近端边缘与跟骨内侧结节之间对跟骨骨骺进行超声扫描。作者将跟骨骨骺的成熟度分为5个阶段，从无骨骺（1期）到完全融合（5期）。足跟痛的诊断基于挤压试验时疼痛的主观报告。使用单因素方差分析或Kruskal-Wallis检验研究成熟阶段与身体特征之间的关系，使用卡方检验研究成熟阶段与足跟痛之间的关系。
在336名运动员中，49名有足跟痛，患病率为14.6%。18名（5.4%）运动员有单侧足跟痛，31名（9.2%）运动员有双侧足跟痛。无足跟痛的运动员与有足跟痛的运动员在跟骨骨骺成熟阶段无显著差异。然而，在跟骨成熟的5期，没有运动员有足跟痛。
日本青年男性棒球运动员足跟痛的患病率为14.6%。跟骨骨骺成熟阶段与足跟痛之间无关联。在跟骨骨骺成熟完全的5期，未出现可能与跟骨骨骺炎相关的足跟痛。
