Compartment Syndrome Mnemonic – “5 P’s”

Compartment Syndrome Mnemonic –

Compartment Syndrome — the orthopedic version of a ticking time bomb. ⏱️
And no, I’m not being dramatic. If you’ve ever seen Dr. Faisal Afridi sprint across the ER shouting “fasciotomy tray, now!” — you know what I mean.

It’s one of those emergencies you can’t afford to miss — because missing it means muscle necrosis, nerve damage, and possibly amputation.
(Don’t worry, I’ll give you a mnemonic. But first, a quick ward story.)

🏥 Real life clinical encounter

Last Eid, a 28-year-old shepherd from Zehri, Balochistan limped into our ER post-motorbike accident — left leg swollen, firm, and “just a little sore.”
“Classic shin hit,” someone mumbled.
But something didn’t sit right — the pain was out of proportion, he couldn’t move his toes, and his calf felt like a cricket bat on palpation.

I called Dr. Faisal Afridi. One look, and he said the dreaded words:

“This is compartment syndrome. We’re taking him in now.”

And thus began the urgent fasciotomy waltz. 💃🩺

🧠 The Mnemonic: 5 P’s of Compartment Syndrome

P Clinical Feature Explanation
Pain Out of proportion to injury First and most important sign. Especially on passive stretch. Watch this one like a hawk. 🦅
Paresthesia Tingling, numbness Nerve ischemia sets in fast. Patients describe it as pins and needles or electric shocks ⚡
Pallor Pale skin distal to compartment Due to compromised arterial inflow — usually a late finding 🚨
Paralysis Weakness or inability to move the limb Also late. If present, the clock’s already ticking fast. Call ortho. NOW. 🏃‍♂️
Pulselessness Absent distal pulses Rare and very late. If you’re waiting for this one, you’re already too late ⌛

 

Common Causes of Compartment Syndrome

  • Crush injuries — post-accident or earthquake trauma (thanks to Quetta’s tremor tantrums).
  • Tight casts — someone got overzealous in plaster room again. 🙃
  • Reperfusion injuries — post-vascular surgery, especially in trauma.
  • Snake bites — especially in patients from Panjgur and Kharan. Seen it twice this year alone. 🐍

Happy learning folks! 🙂
