Traumatic road rash allowing for an incredible view of the flexor muscles and tendons! 🤕😳
There are many muscles that live in the anterior compartment of the ante-brachium (forearm). They allow for flexion of the wrist and the fingers, like shooting a basketball, while resisting extension movements. These muscles can easily be divided into 3 layers (superficial, intermediate, and deep) to give a better understanding of where they lie within the forearm and what nerves/nerve levels innervate them.
SUPERFICIAL LAYER (closest to the skin):
-Flexor Carpi Radialis: median nerve C6, C7
-Palmaris Longus: median nerve C7, C8
-Flexor Carpi Ulnaris: ulnar nerve C8, T1
-Flexor Digitorum Superficialis: median nerve C7, C8, T1
DEEP LAYER (closest to the bone):
-Flexor Digitorum Profundus: median nerve C8, T1
-Flexor Pollicis Longus: median nerve C8, T1
-Pronator Quadratus: median nerve C8, T1
Clinical Relevance: Almost all of these muscles originate in the medial epicondyle of the humerus. Overuse of these flexor muscles can lead to irritation of the origin, resulting in medial epicondylitis (AKA: golfer's or baseball elbow). The most common symptom is pain along the palm side of the forearm, from the elbow to the wrist, on the same side as the little finger. The pain can be felt when bending the wrist toward the palm against resistance, or when squeezing a rubber ball.
If you or a loved one feel like they may be experiencing these symptoms please ask us and contact your primary healthcare physician to prevent any further complications. Stay flexing and stay safe everyone! 💪🤓
