The elbow is a complex joint formed by the articulation of three bones –the humerus, radius and ulna. The elbow joint helps in bending or straightening of the arm to 180 degrees and assists in lifting or moving objects.
The bones of the elbow are supported by
- Ligaments and tendons
- Blood vessels

Bicep Tendon Tear at Elbow
The biceps muscle, located in the front of the upper arm allows you to bend the elbow and rotate the arm. Biceps tendons attach the biceps muscle to the bones in the shoulder and in the elbow.
Biceps tear can be complete or partial. Partial biceps tendon tears will not completely break the tendon. Complete tendon tears will break the tendon into two parts.

The elbow is a hinge joint made up of 3 bones – humerus, radius and ulna. The bones are held together by ligaments to provide stability to the joint. Muscles and tendons move the bones around each other and help in performing various activities. Elbow dislocation occurs when the bones that make up the joint are forced out of alignment.

Elbow Injuries in the Throwing Athlete
An athlete uses an overhand throw to achieve greater speed and distance. Repeated throwing in sports such as baseball and basketball can place a lot of stress on the joints of the arm, and lead to weakening and ultimately, injury to the structures in the elbow.

Osteoarthritis of the Elbow
Although the elbows are not weight-bearing joints, they are considered to be most important for the functioning of the upper limbs. Hence, even minor trauma or disease affecting the elbow may cause pain and limit the movements of the upper limbs. Arthritis is one of the common disease conditions affecting the elbow joint.

Tennis elbow is the common name used for the elbow condition called 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 (lateral epicondyle). It is a painful condition occurring from repeated muscle contractions at the forearm that leads to inflammation and micro tears in the tendons that attach to the lateral epicondyle.

Ulnar Nerve Entrapment (Cubital Tunnel Syndrome)
Cubital Tunnel Syndrome is a condition characterized 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. The cubital tunnel is a narrow passageway on the inside of the elbow formed by bone, muscle, and ligaments with the ulnar nerve passing through its centre. The roof of the cubital tunnel is covered with a soft tissue called fascia.

Golfer’s elbow, also called Medial Epicondylitis, 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 medial epicondyle. The medial epicondyle is the bony prominence that is felt on the inside of the elbow.

Recurrent & Chronic Elbow Instability
The elbow is formed by the junction of the humerus (upper arm bone), and radius and ulna (forearm bones). These three bones articulate to form the elbow joint, which is held and supported by muscles and strong ligaments called the lateral ligament (on the outer side) and ulnar collateral ligament (on the inner side). Injury to these ligaments cause elbow instability and dislocation of the joint.

Elbow Fractures in Children
The elbow is a joint that consists of three bones – the humerus (upper arm bone), radius (forearm bone) and ulna (forearm bone). An elbow fracture most commonly occurs when your child falls on an outstretched arm. It can lead to severe pain in the elbow and numbness in the hand. Fractures are more common in children due to their physical activities as well as their bone properties.

Distal Biceps Rupture
The biceps muscle is located in front of your upper arm. It helps in bending your elbow, rotational movements of your forearm and in maintaining 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.
