Seroma â Definition, Symptoms, Fluid, Treatment, Types. A Seroma is a collection of serous fluid that develops after surgery or any blunt injury. Serous fluid is the fluid compartment of blood that seeps out when blood vessels are injured or ruptured during operation. Inflammation on the surgical site also increases the capillary permeability, thus increasing the flow of plasma from blood vessels into the interstitial spaces (spaces between cells).
A detailed description of the anatomical variations of the median nerve in the carpal tunnel, including the bifid median nerve, was previously reported. The bifid median nerve is a cause of secondary carpal tunnel syndrome due to its relatively higher cross-sectional area compared with a nonbifid median nerve. Magnetic resonance imaging (MRI) and ultrasound can be obtained to show bifid median nerves, helping surgeons avoid potential surgical hazards.
The unbranched portion of the median nerve (which arises from the cubital fossa) innervates muscles of superficial and intermediate groups of the anterior(flexor) compartment except flexor carpi ulnaris.he median nerve originates from the lateral and medial cords of the brachial plexus, and has contributions from ventral roots of C5 & C6 (lateral cord) and C8 & T1 (medial cord).
