冬季为何是骨折的"高发季"？ 一到冬天，关节疼痛、肌肉僵硬、骨质疏松等病症就成了骨科、康复科门诊的"常客"。 中新网北京12月26日电(记者 赵方园)随着大部分地区气温降至0℃以下，全国入冬进度条不断加载，也 迎来了护骨养骨的关键时刻。 为什么天冷时我们的骨骼似乎变得更"脆"？哪些信号是关节发出的"求救"警报？中新健康邀请了浙江大 学医学院附属邵逸夫医院骨科副主任医师徐文斌进行解答。徐文斌表示，冬季气温低，人体血液循环较 慢，会使人反应迟钝，肢体协调性下降。 从身体内部看，低温首先引发血管的收缩痉挛。这导致流向关节和骨骼的血液减少，局部组织陷入"营 养不良"的状态，代谢废物和炎性物质容易淤积，从而引发或加重疼痛与不适。 这三类人群需格外警惕骨折风险 一是老年人。随着年龄增长，骨量流失导致的骨质疏松使骨骼变"脆"，加之反应速度、肌肉力量与平衡 能力下降，使他们一旦摔倒，极易发生腕部、髋部或脊柱骨折。 二是儿童和青少年。这个阶段骨骼还在发育，骨骺端比较脆弱，加上孩子活泼好动，容易因碰撞导致骨 折。 三是特殊疾病人群，如骨质疏松症、糖尿病、甲状腺疾病患者，以及长期服用激素的人，骨骼强度都会 受影响。另外，缺乏运动、 ...
