To determine the prevalence of chronic wrist injuries among adolescent gymnasts and the consequences of repetitive stress.
Students of a Chinese opera school underwent radiography of both wrists and answered a questionnaire. They were separated into study (n = 261) and control (n = 63) groups according to participation in or abstinence from exercise training, respectively. They were further separated into fused and unfused physis subgroups. The ulnar variance was measured on posteroanterior radiographs. Abnormalities of distal radii were investigated.
An increase in both mean ulnar variance and frequency of ulnar-plus variance was noted in the study subgroups. Fourteen (8.2%) of 170 wrists of the fused physis study subgroup had an exceedingly large ulnar-plus variance. Sixty-one (17.3%) of 352 wrists had abnormal morphology of the distal radii in the unfused physis study subgroup. Widening of the physis was the most common finding.
Chronic, repetitive stress in the wrists of adolescent gymnasts results in a localized growth disturbance of the distal radius with resultant ulnar-plus variance. Stress injuries of the physis may lead to permanent sequelae, even in asymptomatic individuals.
确定青少年体操运动员慢性腕部损伤的患病率以及重复性应力的后果。
一所戏曲学校的学生接受了双腕部X线摄影并回答了一份问卷。根据是否参与运动训练，他们被分别分为研究组（n = 261）和对照组（n = 63）。他们又进一步被分为骨骺融合组和未融合组亚组。在正位X线片上测量尺骨变异。对桡骨远端异常情况进行调查。
研究亚组中平均尺骨变异和尺骨正向变异频率均增加。骨骺融合研究亚组的170例腕部中有14例（8.2%）存在极大的尺骨正向变异。未融合骨骺研究亚组的352例腕部中有61例（17.3%）桡骨远端形态异常。骨骺增宽是最常见的表现。
青少年体操运动员腕部的慢性重复性应力会导致桡骨远端局部生长紊乱，从而产生尺骨正向变异。骨骺应力损伤可能导致永久性后遗症，即使是无症状个体。
