An Overview on PRP Injections for the Elbow Joint
Patients in the Chicago, Westchester, Oak Brook and Hinsdale, Illinois area actively involved in tennis and golf commonly report elbow pain and inflammation. In addition, lateral elbow pain is commonly seen in association with repetitive manual work. Many of these patients are later diagnosed with lateral epicondylitis, commonly known as tennis elbow, or medial epicondylitis, commonly referred to as golfer’s elbow. Caused by chronic overuse to the elbow joint, tennis elbow and golfer’s elbow can be extremely painful conditions. Dr. Nikhil Verma, elbow specialist, offers an innovative treatment option for patients suffering from an elbow overuse injury, PRP injections in the elbow. Platelet rich plasma is sometimes referred to as blood PRP since it utilizes a patient’s own blood to accelerate the body’s healing response after an elbow injury.
The elbow joint is made up of three bones- the humerus (upper arm bone) and the two bones in the forearm (radius and ulna). There are bony bumps at the bottom of the humerus called epicondyles. The bony bump on the outside of the elbow (lateral side) is called the lateral epicondyle and the bony bump on the inside of the elbow (medial side) is called the medial epicondyle. Elbow anatomy also includes a complex system of ligaments, tendons and muscles that hold the joint together and provide stability and joint function.
What is Golfer’s Elbow?
Medial epicondylitis, more commonly known as golfer’s elbow, involves damage to the wrist flexors on the inner portion of the elbow. Wrist flexors are the muscles in the palm side of the forearm that pulls the wrist down. Most of the wrist flexor tendons attach to the medial epicondyle. As the wrists flex and form a grip, the forearm muscles tighten and pull on the tendons. During a golf swing, force is put on the flexor muscles and the tendons attaching these muscles to the medial epicondyle in the elbow. When the wrist flexor tendons are weakened due to overuse, microscopic tendon tears occur where the tendon attaches to the medial epicondyle. These microscopic tears lead to inflammation and pain, which causes golfer’s elbow.
What is Tennis Elbow?
Tennis elbow is similar to golfer’s elbow, but it occurs on the outside rather than the inside of the elbow joint. Lateral epicondylitis, more commonly known as tennis elbow, involves damage to the muscles and tendons on the outer portion of the forearm. The forearm muscles extend the wrist and fingers, which is repetitively used in the groundstroke of tennis. The main tendon associated with tennis elbow is called the Extensor Carpi Radialis Brevis (ECRB), which attaches to the lateral epicondyle. The position of the ECRB is at risk due to the position – as the elbow bends and straightens the muscles rub against the epicondyles. When the ECRB is weakened from overuse, microscopic tendon tears occur where the tendon attaches to the lateral epicondyle. These microscopic tears lead to inflammation and pain, which causes tennis elbow.
