Which symptom is NOT one of the 5 P's of compartment syndrome?

• A. Pain
• B. Palpable pulse
• C. Pallor
• D. Paresthesia

Answer: (B)

In the context of compartment syndrome, the five "P's" typically recognized are Pain, Pallor, Paresthesia, Pulselessness, and Pressure. Each of these symptoms helps clinicians assess the presence and severity of compartment syndrome.

The correct answer identifies "Palpable pulse" as not being one of the classic five symptoms. In fact, one of the key signs associated with compartment syndrome is "Pulselessness," which indicates that blood flow has been compromised due to increased pressure in the compartment.

In a healthy situation, a palpable pulse would be present, indicating adequate blood supply and circulation to the affected area. However, during compartment syndrome, if the condition progresses and is severe enough, a pulse may become absent. Therefore, while "palpable pulse" suggests normal circulation, this symptom does not belong in the classic group of signs for compartment syndrome, which aim to indicate potential ischemia or compromised blood flow. Understanding these distinctions is crucial for effective assessment and intervention in sports medicine and athletic training scenarios.
