🟦 對話稿 Dialogue(中英對照)
Koala:
指骨是什麼? What are phalanges?
BOSS 醫生:
指骨就是構成手指的細長骨頭。
Phalanges are the slender bones that form the fingers.
Koala:
每一根手指都有一樣多的指骨嗎?
Does each finger have the same number of phalanges?
BOSS 醫生:
幾乎一樣,但拇指少一節!
Almost — but the thumb has one less segment!
👉 拇指 Thumb
近端指骨 Proximal phalanx 遠端指骨 Distal phalanx
👉 其他四指 Other four fingers
1️⃣ 食指 Index finger
近端 Proximal 中節 Middle 遠端 Distal
2️⃣ 中指 Middle finger
近端 Proximal 中節 Middle 遠端 Distal
3️⃣ 無名指 Ring finger
近端 Proximal 中節 Middle 遠端 Distal
4️⃣ 小指 Little finger
近端 Proximal 中節 Middle 遠端 Distal
🟦 結構篇 Structure(中英對照)
BOSS 醫生:
指骨負責精細動作與抓握穩定。
Phalanges enable fine motor control and grip stability.
骨頭 Bones
共 14 塊指骨 Total 14 phalanges 拇指 2 塊 Thumb has 2 其餘每指 3 塊 Each other finger has 3
關節 Joints
指間關節 Interphalangeal joints (IP joints)
近端指間關節 PIP joints
遠端指間關節 DIP joints
拇指只有一個 IP
關節 The thumb has only one IP joint
功能 Function
彎曲 Flexion
伸直 Extension
精細操作 Fine manipulation
🟦 日常使用 Daily Use(中英對照)
Koala:
指骨平常都在做什麼? What do phalanges do every day?
BOSS 醫生:
一句話:Phalanges = 精細動作的主角
舉例 Examples:
滑手機 Scrolling on a phone
寫字 Writing
扣鈕扣 Buttoning a shirt
拿筆 Holding a pen
彈鋼琴 Playing the piano
使用滑鼠 Using a mouse
🟦 習慣與保養 Habits & Care(中英對照)
BOSS 醫生:
常見壓力來源 Common stress sources:
長時間打字 Prolonged typing
頻繁滑手機 Repetitive phone scrolling
長期關節彎曲姿勢 Sustained flexed posture
運動撞擊 Sports impact
改善方式 Tips for Improvement:
手指伸展運動 Finger stretching exercises
握力球訓練 Grip ball training
避免長時間固定姿勢 Avoid prolonged static positions
補充關節活動度訓練 Joint mobility training
🟦 小知識 Mini Note(中英對照)
Koala:
為什麼遠端指間關節容易變形? Why do distal interphalangeal joints often deform?
BOSS 醫生:
因為遠端指骨最細小,長期重複使用或退化容易造成骨關節炎,例如常見的「赫伯登結節」。
The distal phalanges are small and frequently used, making them prone to osteoarthritis, such as Heberden’s nodes.
