Complex regional pain syndrome (CRPS type 1 and type 2), sometimes referred to by the hyponyms reflex sympathetic dystrophy (RSD) or reflex neurovascular dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms.
Complex regional pain syndrome is characterized by pain that is distributed regionally, usually starts in an extremity distally, occurs after a trauma, and is disproportionate in severity or duration compared to the expected course of the trauma — the sites affected by complex regional pain syndrome experience autonomic and inflammatory changes.
Compartment syndrome is a serious condition. [5] Increased pressure in a body compartment can harm blood flow and tissue function. [5] [6] [7] If not treated quickly, it may cause permanent damage. [7] There are two types, acute and chronic. [8] Acute compartment syndrome can lead to a loss of the affected limb due to tissue death. [6] [9]
Complex regional pain syndrome is a term for any amount of spontaneous regional pain lasting longer than the expected recovery time of an observed physical trauma, or other injury. This includes two separate types: type I and type II.
A compartment space is anatomically determined by an unyielding fascial (and osseous) enclosure of the muscles.The anterior compartment syndrome of the lower leg (often referred to simply as anterior compartment syndrome), can affect any and all four muscles of that compartment: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius.

The most important signs and symptoms of compartment syndrome are observable before actual contracture. What is known as the five Ps of compartment syndrome include: pain, generally the initial symptom, accompanied by pulselessness, pallor, paralysis, and paraesthesias. Pain will likely also increase upon extension of the affected limbs hands ...
