The elbow is a complex structure. It consists of three bones, the joints between them, the ligaments that keep it stable and the muscles that generate strength and motion. Your elbows take a lot of stress from regular movements like lifting or carrying a bag to more complex motions like throwing a baseball. The muscles that surround the elbow are also used for motion in the wrist. Elbow problems can be caused by overuse, traumatic injury, and/or changes that occur naturally in your body.

How Your Elbow Works
The elbow consists of three bones: the upper arm bone (humerus) and two bones in the forearm the ulna and the radius. The ulna bone runs on the bottom side of your forearm, from the wrist to the elbow and is the bone used to rest your arms. It has a U-shape to it that holds the bottom of the upper arm bone (humerus). The radius is the other bone in the forearm and it rotates around the ulna. These bones, the radius and ulna, are responsible for turning the palm of your hand up and down.
There are two main ligaments in the elbow that help provide stability. These ligaments are commonly injured in sports or during traumatic injuries. The radial collateral ligament provides stability to the outside of the elbow while the ulnar collateral ligament (UCL) provides stability to the inside of the elbow. The UCL is more commonly injured as this ligament can be stretched with throwing or racket-type sports.
Surrounding the elbow joint, there are four main groups of muscles that help power the elbow and wrist. The biceps muscles are located on the front of the upper arm bone, which bend the elbow. On the backside of the upper arm bone are the triceps muscles, which straighten the elbow. Some wrist flexor tendons attach on the outside of the elbow while the wrist extensors attach to inside of the elbow. These muscles all work together to allow the hand to turn palm up and palm down as well as bend and straighten the elbow.
There are two main nerves that can cause pain in the elbow and numbness/weakness in the hand, the ulnar nerve and radial nerve. The ulnar nerve travels behind the inside of your elbow and is the nerve responsible for the zinging pain down into your hand when you hit your “funny bone”. This nerve provides feeling for your little finger and half of your ring finger on the palmar side of the hand. The radial nerve travels through the muscle of your forearm and provides some sensation to the back of your hand but primarily is responsible for powering the muscles in the forearm and hand.
Evaluating Elbow Pain
Evaluation for elbow pain starts with you giving us a history of your problem: when and how it started, how it currently feels, and which treatments you have tried so far. We also ask you about other medical conditions that may contribute to your elbow pain. We do a physical exam to test the structures of your elbow. We check your elbow’s range of motion, strength and do special tests that can uncover specific problems.
Based on the findings of your physical exam, we may recommend a cortisone injection as both a clinical test and treatment for your pain. The numbing medicine mixed in the injection helps us determine the source of your pain, whereas the cortisone medication of the injection can provide pain relief. Sometimes we order tests such as x-rays or MRIs to visualize your bones and soft tissues. X-rays can show us things like fractures, spurs, and changes from arthritis. MRIs can show us more detail of the bones, as well as soft tissue damage like tears of the ligaments or the tendons.
Whatever the cause of your elbow pain, we are dedicated to helping you find the best treatment. Request an appointment today.
