Overview

当骨弯曲和破裂,但是没有完全裂成碎片时,则发生青枝骨折。这种骨折看起来与试图折断树上一段小“青”枝的情况类似。

大多数青枝骨折发生在 10 岁以下儿童中。这种骨裂类型常见于儿童,因为他们的骨比成人的软,且更易弯曲。

即使轻度青枝骨折,通常也用石膏固定。除了将骨折块接在一起使其愈合之外,石膏还可帮助防止儿童在跌倒时骨发生完全断裂。

症状

体征和症状各有不同,取决于青枝骨折的严重程度。轻度骨折可能会被误认为是扭伤或擦伤。较严重的青枝骨折可能引起明显的畸形,伴显著疼痛和肿胀。

何时就诊

如果孩子受伤的肢体持续疼痛,请联系医生。如果孩子无法承受重量,或出现明显的疼痛、畸形和肿胀,请立即就医。

病因

儿童骨折最常见于跌倒时。手臂骨折比腿部骨折更常见,因为您跌倒时,共同反应是伸出手臂支撑自己。

风险因素

幼儿发生青枝骨折的风险较高,这是因为他们的骨骼比成人的软,更易弯曲。一旦发生青枝骨折,骨骼便会弯折并开裂,而不是断成单独的碎片。大多数青枝骨折发生在 10 岁以下的儿童中。
