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 median nerve is the nerve that runs through the carpal tunnel of the wrist and connects with the thumb and all fingers of the hand, with the exception of the little finger. This nerve originates with the cervical spine and is routed through the arm and forearm. The nerve gathers in compressed form to run through the narrow carpal tunnel and to the fingers. In addition to controlling sensation in the hand, it is also important to the general nerve function of the upper portion of the arm. In relation to the hand, the median nerve controls all sensation and nerve function on the palm side of the thumb. The nerve also manages the process of sensation for the index and middle fingers, and half of the ring finger.
