To investigate the effects of long-term diving on the morphology and growth of the distal radial epiphyseal plate in young divers.
Cohort study.
Guangzhou Sport University.
Thirty-eight professional divers, aged 10 to 17 years, and 25 age-matched volunteers.
Each subject received a physical examination at the beginning of the study and underwent bilateral magnetic resonance imaging of the wrist. The divers were divided into 2 groups depending on the status of the epiphyseal plate: group A (positive distal radial epiphyseal plate injury) and group B (no positive distal radial epiphyseal plate injury). A third group, group C, consisted of the 25 volunteers.
The frequency of distal radial epiphyseal plate injury and the thickness of the distal radial epiphyseal plate were analyzed across the 3 groups.
Twenty-nine cases (29/76, 38.15%) of distal radial epiphyseal plate injury were observed in 20 divers (20/38, 52.63%). The incidence of injury to the right hand was higher than that for the left (P = 0.009). There were statistically significant differences (P = 0.000) among the 3 groups in terms of epiphyseal plate thickness; group A > group B > group C.
Distal radial epiphyseal plate injury is common in divers, and more injuries are seen in the right hand. Moreover, growth of the radius was impaired in divers relative to controls. We consider that loading during diving may influence growth of the epiphyseal plate in either a transient or permanent manner.
探讨长期潜水对青少年桡骨远端骺板形态和生长的影响。
队列研究。
广州体育学院。
38 名年龄在 10 至 17 岁的专业潜水员和 25 名年龄匹配的志愿者。
每位受试者在研究开始时接受体检，并进行腕关节双侧磁共振成像。根据骺板的状态将潜水员分为 2 组：A 组（桡骨远端骺板阳性损伤）和 B 组（无桡骨远端骺板阳性损伤）。第 3 组为 C 组，由 25 名志愿者组成。
分析 3 组桡骨远端骺板损伤的频率和桡骨远端骺板的厚度。
在 20 名潜水员（20/38，52.63%）中观察到 29 例（29/76，38.15%）桡骨远端骺板损伤。右手损伤的发生率高于左手（P=0.009）。骺板厚度在 3 组之间存在统计学差异（P=0.000）；A 组>B 组>C 组。
桡骨远端骺板损伤在潜水员中较为常见，且右手损伤更为多见。此外，与对照组相比，潜水员的桡骨生长受到了损害。我们认为，潜水过程中的负荷可能以暂时或永久性的方式影响骺板的生长。
