Elbow

Normal Anatomy of the Elbow

The arm in the human body is made up of three bones that join together to form a hinge joint called the elbow. The upper arm bone or humerus connects from the shoulder to the elbow forming the top of the hinge joint. The lower arm or forearm consists of two bones, the radius and the ulna. These bones connect the wrist to the elbow forming the bottom portion of the hinge joint.

Tennis Elbow

Tennis elbow is the common name for the elbow condition lateral epicondylitis. It is an overuse injury that causes inflammation of the tendons that attach to the bony prominence on the outside of the elbow. It is a painful condition occurring from repeated muscle contractions in the forearm that leads to inflammation and microtears in the tendons that attach to the lateral epicondyle. The lateral epicondyle is the bony prominence that is felt on the outside of the elbow and the condition is more common in sports individuals playing tennis.

Cubital Tunnel Syndrome

Cubital tunnel release surgery is the surgery to correct the cubital tunnel syndrome. Cubital tunnel syndrome, also called ulnar nerve entrapment is a condition caused by compression of the ulnar nerve in an area of the elbow called the cubital tunnel. The ulnar nerve travels down the back of the elbow behind the bony bump called the medial epicondyle and through a passageway called the cubital tunnel.

Elbow Arthroscopy

The elbow is the joint that connects the upper arm bone and the forearm bones. Elbow joint helps in movement of the arms forward, backward, as well as to twist the arms inside and outside. Elbow joint may get affected by inflammation, injury, or other disease conditions causing severe pain and requiring surgical treatment. Arthroscopy is a minimally invasive surgery performed using a tiny device called arthroscope.

Biceps Tendon Repair

The biceps muscle is located in front of your upper arm. It helps in bending your elbow as well as in rotational movements of your forearm. Also, it helps to maintain stability in the shoulder joint. The biceps muscle has two tendons, one of which attaches it to the bone in the shoulder and the other attaches at the elbow. The biceps tendon at the elbow is called the distal biceps tendon and if there is a tear in this tendon, you will be unable to move your arm from the palm-down to palm-up position.
