Ligament reconstruction is considered in patients with ligament rupture. Your surgeon will make an incision over the elbow. Care is taken to move muscles, tendons, and nerves out of the way. The donor's tendon is harvested from either the forearm or below the knee.
Golfer’s elbow is a condition associated with pain on the inside of the elbow where tendons of your forearm attach to the bony prominence (medial epicondyle). It is also called medial epicondylitis and is caused by injury or irritation to the tendons which can become painful and swollen.
The common extensor tendon is a tough band of fibrous connective tissue that attaches to the lateral epicondyle of the humerus (long bone in the upper arm) at the elbow. Rupture or tear of the common extensor tendon is the most common acute tendon injury of the elbow.
A humerus fracture is a condition that occurs when there is a break in the humerus or upper arm bone that commonly occurs as a result of severe trauma. Fracture of the humerus can affect the movement and function of your arm as well as your work and activities of daily living.
Elbow fracture reconstruction is a surgical procedure employed to repair and restore the appearance and full function of a damaged elbow caused by severe trauma or injury. This may include repairing damaged structures or replacing missing or damaged structures with adjoining skin, muscles, ligaments, tendons, bones, or nerves to restore the appearance and function.
A distal humerus fracture is a condition that occurs when there is a break in the lower end of the humerus bone that commonly occurs as a result of severe trauma. Fracture of the distal humerus can affect the movement and function of your arm as well as your work and activities of daily living.
Olecranon fractures are described as a break in the bony tip of the elbow that sticks out when you bend your arm. A fracture of the olecranon bone can be very painful and make motion of the elbow difficult or impossible. This kind of fracture is common and normally happens in isolation (with no other injuries involved).
UCL repair with an internal brace is a surgery that involves the use of collagen-coated tape (internal brace) surgically placed at the site of the damaged UCL ligaments. It provides better resistant and a faster recovery compared to traditional reconstruction surgery that involves the use of graft tissue from your body.
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.
The elbow is a complex joint of the upper limb, formed by the articulation of the long bone of the upper arm or humerus, and the two bones of the forearm - the radius and ulna. It is one of the important joints of the upper limb and is involved in basic movements such as bending and extending the arm and rotating the forearm.
A biceps tear can be complete or partial. Partial biceps tendon tears will not completely break the tendon while complete tendon tears will break the tendon into two parts. Tears of the distal biceps tendon are usually complete and the muscle is separated from the bone. Tears of the distal biceps tendon most often result from a sudden injury or lifting a heavy object.
Radial head fractures are very common and occur in almost 20% of acute elbow injuries. Elbow dislocations are generally associated with radial head fractures. Radial head fractures are more common in women than in men and occur more frequently in the age group of 30 to 40 years.
Inflammation of the olecranon bursa leads to a condition called olecranon bursitis. The causes of elbow bursitis may include trauma or a hard blow on the elbow, excessive leaning on the elbow, infection by puncture wounds or insect bites, or conditions such as gout and rheumatoid arthritis.
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.
Osteochondritis dissecans is a joint condition in which a piece of cartilage, along with a thin layer of bone separates because of inadequate blood supply. The separated fragments are sometimes called “joint mice”. These fragments may be localized or may detach and fall into the joint space, causing pain and joint instability.
Posterior elbow impingement is a medical condition characterized by compression and injury of soft tissue structures such as cartilage at the posterior aspect (back) of the elbow joint. The impingement is caused by repetitive forced extensions and overuse of the elbow.
Lateral elbow impingement is a medical condition characterized by compression and injury of the soft tissue structures, such as cartilage located at the outer aspect of the elbow joint. The impingement is caused by repetitive forced extensions and overuse of the elbow.
Hyperextension injury of the elbow occurs when the elbow joint is bent beyond its normal range of motion, causing damage to the bones and ligaments of the elbow. It may also cause elbow dislocation. The condition is more common in tennis, football, weight-lifting and contact sports.
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.
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
- 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 backwards
- 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 fibres 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 fibres 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.
