Tennis Elbow

Tennis elbow is a common name for the elbow condition lateral epicondylitis. It is an overuse injury that causes inflammation and microtears of the tendons that attach to the lateral epicondyle.

Golfer's Elbow

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.

Throwing Injuries

Throwing Injuries

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.

Elbow Injuries

The elbow is a complex joint formed by the articulation of three bones – the humerus, radius, and ulna. Articular cartilage lines the articulating regions of the humerus, radius, and ulna.

Triceps Injuries

Triceps Injuries

The triceps or triceps brachii is a crucial muscle of the upper arm (humerus). It runs along the upper arm bone between the shoulder and elbow.

Elbow Sprain

An elbow sprain is an injury to the soft tissues of the elbow. It is caused due to stretching or tearing (partial or full) of the ligaments that support the elbow joint.

Although the elbows are not weight-bearing joints, they are considered to be most important for the functioning of the upper limbs.

triceps-tendon-repair

Triceps Tendonitis

Triceps tendonitis is inflammation of the triceps tendon, the tissue that connects the triceps muscle on the back of the upper arm to the back of the elbow joint, allowing you to straighten your arm back after you have bent it.

Cubital Tunnel Syndrome (Ulnar Nerve Entrapment)

When the elbow is bent, the ulnar nerve can stretch and catch on the bony bump. When the ulnar nerve is compressed or entrapped, the nerve can tear and become inflamed, leading to cubital tunnel syndrome.

Radial Tunnel Syndrome

Radial Tunnel Syndrome

Radial tunnel syndrome is a painful condition caused by pressure on the radial nerve of the forearm. The entrapment or compression occurs frequently in the proximal forearm in the radial tunnel; a narrow space formed by muscles, bone, and tendon near the elbow joint.

Little League Elbow

Little League Elbow

Little league elbow, also called medial apophysitis, is an overuse condition that occurs when there is overstress or injury to the inside portion of the elbow. It is commonly seen in children involved in sports activities that require repetitive throwing such as baseball.

Ulnar Nerve Neuropathy

Ulnar nerve neuropathy is the entrapment or compression of the ulnar nerve causing impairment of its function.

Loose Bodies in the Elbow

Loose Bodies in the Elbow

Your elbow is a joint made up of three bones held together by muscles, ligaments, tendons, and cartilage. It is both a hinge and pivot joint allowing you to bend and rotate your elbow freely. Loose bodies in your elbow are small pieces of bone or cartilage that have broken off and are lying or floating free within the joint. They can make elbow movement such as bending or rotation difficult.

A ligament is a band of elastic, tough fibrous connective tissue around a joint. It attaches bone to bone, supports and holds them together and limits the joint's movement.

Elbow Arthroscopy

Elbow Arthroscopy

Elbow arthroscopy, also referred to as keyhole or minimally invasive surgery, is a surgical procedure that is performed through tiny incisions to evaluate and treat several elbow conditions.

Ulnar Nerve Transposition

The ulnar nerve is one of the 3 main nerves in the arm that travels down from the neck through a bony protuberance inside the elbow (medial epicondyle), under the muscles of the forearm and down the hand on the side of the palm, towards the little finger.

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 lifting or moving objects.

The bones of the elbow are supported by:

  • Ligaments and tendons
  • Muscles
  • Nerves
  • Blood vessels

Bones and Joints of the Elbow

The elbow joint is formed at the junction of three bones:

  • The humerus (upper arm bone) forms the upper portion of the joint. The lower end of the humerus divides into two bony protrusions known as the medial and lateral epicondyles, which can be felt on either side of the elbow joint.
  • The ulna is the larger bone of the forearm located on the inner surface of the joint. It articulates with the humerus.
  • The radius is the smaller bone of the forearm situated on the outer surface of the joint. The head of the radius is circular and hollow, which allows movement with the humerus. The articulation between the ulna and radius helps the forearm to rotate.

The elbow consists of three joints, namely:

  • The humeroulnar joint is formed between the humerus and ulna and allows flexion and extension of the arm.
  • The humeroradial joint is formed between the radius and humerus and allows movements like flexion, extension, supination, and pronation.
  • The radioulnar joint is formed between the ulna and radius bones and allows rotation of the lower arm.

Articular cartilage lines the articulating regions of the humerus, radius, and ulna. It is a thin, tough, flexible and slippery surface that acts as a shock absorber and cushion to reduce friction between the bones. The cartilage is lubricated with synovial fluid, which further enables the smooth movement of the bones.

Muscles of the Elbow Joint

There are several muscles extending across the elbow joint that help in various movements. These include the following:

  • Biceps brachii: Upper arm muscle, enabling flexion of the arm
  • Triceps brachii: Muscle in the back of the upper arm that extends the arm and fixes the elbow during fine movements
  • Brachialis: Upper arm muscle beneath the biceps, which flexes the elbow towards the body
  • Brachioradialis: Forearm muscle that flexes, straightens and pulls the arm at the elbow
  • Pronator teres: Muscle that extends from the humeral head, across the elbow, and towards the ulna, and helps to turn the palm facing backward
  • Extensor carpi radialis brevis: Forearm muscle that helps in movement of the hand
  • Extensor digitorum: Forearm muscle that helps in movement of the fingers

Ligaments and Tendons of the Elbow

The elbow joint is supported by ligaments and tendons, which provide stability to the joint.

Ligaments are a group of firm tissues that connect bones to other bones. The most important ligaments of the elbow joint are the:

  • Medial or ulnar collateral ligament: Comprised of triangular bands of tissue on the inner side of the elbow joint
  • Lateral or radial collateral ligament: A thin band of tissue on the outer side of the elbow joint
  • Annular ligament: Group of fibers that surround the radial head, and hold the ulna and radius tightly in place during movement of the arm

Together, the medial and lateral ligaments are the main source of stability and hold the humerus and ulna tightly in place during movement of the arm.

The ligaments around a joint combine to form a joint capsule that contains synovial fluid.

Any injury to these ligaments can lead to instability of the elbow joint.

Tendons are bands of connective tissue fibers that connect muscle to bone. The various tendons that surround the elbow joint include:

  • Biceps tendon: attaches the biceps muscle to the radius, allowing the elbow to bend
  • Triceps tendon: attaches the triceps muscle to the ulna, allowing the elbow to straighten

Nerves of the Elbow

The main nerves of the elbow joint are the ulnar, radial and median nerves. These nerves transfer signals from the brain to the muscles that aid in elbow movements. They also carry sensory signals such as touch, pain, and temperature back to the brain.

Any injury or damage to these nerves causes pain, weakness or joint instability.

Blood Vessels Supplying the Elbow

Arteries are blood vessels that carry oxygen-pure blood from the heart to the hand. The main artery of the elbow is the brachial artery that travels across the inside of the elbow and divides into two small branches below the elbow to form the ulnar and the radial artery.
