Shoulder Anatomy

The shoulder is the most flexible joint in the body enabling a wide range of movements including, forward flexion, abduction, adduction, external rotation, internal rotation, and 360-degree circumduction.

Thus, the shoulder joint is considered the most insecure joint of the body but the support of ligaments, muscles and tendons function to provide the required stability.

Elbow Anatomy

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.

Conditions

Rotator Cuff Tear

Rotator cuff is the group of tendons in the shoulder joint providing support and enabling wider range of motion. Major injury to these tendons may result in tear of these tendons and the condition is called as rotator cuff tear. It is one of the most common causes of shoulder pain in middle aged adults and older individuals.

Shoulder Pain

Pain in the shoulder suggests a shoulder injury which is more common in athletes participating in sports such as swimming, tennis, pitching and weightlifting. The injuries are caused due to the over usage or repetitive motion of the arms.

Subluxation

The shoulder is a highly mobile ball and socket joint. The ball of the upper arm bone (humerus) is held in place at the socket (glenoid) of the shoulder blade (scapula) by a group of ligaments. A partial dislocation of the shoulder joint is termed as a subluxation. This means the ball has partially moved out of the glenoid as opposed to a dislocation, where the ball completely moves out of the glenoid. Subluxation usually occurs from falls or a direct blow to your shoulder.

Shoulder Impingement

Shoulder impingement is the condition of inflammation of the tendons of the shoulder joint. It is one of the most common causes of pain in the adult shoulder. The shoulder is a 'ball-and-socket' joint. A ‘ball' at the top of the upper arm bone, humerus, fits neatly into a 'socket’, called the glenoid, which is part of the shoulder blade, scapula. Shoulder impingement is also called as swimmer’s shoulder, tennis shoulder, or rotator cuff tendinitis.

SLAP Tears

The shoulder joint is a ball and socket joint. A 'ball' at the top of the upper arm bone (the humerus) fits neatly into a 'socket', called the glenoid, which is part of the shoulder blade (scapula). The term SLAP (superior –labrum anterior-posterior) lesion or SLAP tear refers to an injury of the superior labrum of the shoulder. The labrum is a ring of fibrous cartilage surrounding the glenoid for stabilization of the shoulder joint.

Arthritis of the Shoulder

The term arthritis literally means inflammation of a joint, but is generally used to describe any condition in which there is damage to the cartilage. Damage of the cartilage in the shoulder joint causes shoulder arthritis. Inflammation is the body's natural response to injury. The warning signs that inflammation presents are redness, swelling, heat and pain.

Frozen Shoulder

Frozen shoulder, also called adhesive capsulitis is a condition characterized by pain and loss of motion in shoulder joint. It is more common in older adults aged between 40 and 60 years and is more common in women than men.

Shoulder Instability

Shoulder instability is a chronic condition that causes frequent dislocations of the shoulder joint.

A dislocation occurs when the end of the humerus (the ball portion) partially or completely dislocates from the glenoid (the socket portion) of the shoulder. A partial dislocation is referred to as a subluxation whereas a complete separation is referred to as a dislocation.

Shoulder Joint Tear

The shoulder joint is a “ball and socket” joint that enables the smooth gliding and thereby the movements of arms. However, it is inherently unstable because of the shallow socket. A soft rim of cartilage, the labrum lines the socket and deepens it so that it accommodates the head of the upper arm bone better.

Dislocated Shoulder

Playing more overhead sports activities and repeated use of shoulder at workplace may lead to sliding of the upper arm bone, the ball portion, from the glenoid–the socket portion of the shoulder. The dislocation might be a partial dislocation (subluxation) or a complete dislocation causing pain and shoulder joint instability. Shoulder joint often dislocates in the forward direction (anterior instability) and it may also dislocate in backward or downward direction.

Little League Shoulder

Little league shoulder is an injury to the growth plate of the upper arm bone in the shoulder joint of children. It is caused due to overuse from pitching or throwing, especially in children between the ages of 10 to 15 years. This condition is mostly seen in baseball pitchers, but children in other sports who use improper throwing action are also at risk.

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.

Bicep Tendon Rupture

The biceps muscle is present on the front side of your upper arm and functions to help you bend and rotate your arm.

The biceps tendon is a tough band of connective fibrous tissue that attaches your biceps muscle to the bones in your shoulder on one side and the elbow on the other side.

Elbow Dislocation

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 (Olecranon) Bursitis

The elbow contains a large, curved, pointy bone at the back called the olecranon, which is covered by the olecranon bursa, a small fluid-filled sac that allows smooth movement between the bone and overlying skin. Inflammation of this bursa leads to a condition called olecranon bursitis.

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 center. The roof of the cubital tunnel is covered with a soft tissue called fascia.

Osteochondritis Dissecans

Osteochondritis dissecans is a joint condition in which a piece of cartilage, along with a thin layer of the bone separates from the end of the bone 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.

Elbow Sprain

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 which support the elbow joint. Ligaments are a group of fibrous tissues that connect one bone to another in the body.

Tennis Elbow

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.

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. The medial epicondyle is the bony prominence that is felt on the inside of the elbow.

Elbow Injuries

Elbow Fractures: Fracture is a common injury to the elbow. Elbow fractures may result from a fall onto an outstretched wrist, a direct impact to the elbow or a twisting injury. Elbow fractures may cause severe pain, swelling, tenderness and painful movements. If a fracture is suspected, immediate intervention by your doctor is necessary. Surgery is often required if a bony displacement is observed.

Little League Elbow

Little league elbow also called as 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.

Nursemaid’s Elbow

Dislocation of the radius bone present in the elbow is called nursemaid’s elbow. This condition is very common among children below 5 years of age as their bones and muscles are still in the developing stage. This condition usually occurs when a child is pulled up too hard by the arm, but can also occur due to a fall or swinging your child by the arms.

Elbow Pain

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.

Fractures/ Injuries

Shoulder Trauma

Shoulder injuries most commonly occur in athletes participating in sports such as swimming, tennis, pitching, and weightlifting. The injuries are caused due to the over usage or repetitive motion of the arms.

Clavicle Fracture

Clavicle fracture, also called broken collarbone is a very common sports injury seen in people who are involved in contact sports such as football and martial arts as well as impact sports such as motor racing. A direct blow over the shoulder that may occur during a fall on an outstretched arm or a motor vehicle accident may cause the clavicle bone to break. Broken clavicle may cause difficulty in lifting your arm because of pain, swelling and bruising over the bone.

Fracture of the Shoulder Blade

The scapula (shoulder blade) is a flat, triangular bone providing attachment to the muscles of the back, neck, chest and arm. The scapula has a body, neck and spine portion.

Scapular fractures are uncommon but do occur and require a large amount of force to fracture. They are usually the result of intense trauma, such as a high-speed motor vehicle accident or a fall from height onto one’s back. They can also occur from a fall on an outstretched arm if the humeral head impacts on the glenoid cavity.

Adult Forearm Fractures

The forearm is made up of 2 bones, namely, the radius and ulna. The primary function of your forearm is rotation i.e., the ability to turn your palm up and down. The fracture of the forearm affects the ability to rotate your arm, as well as bend and straighten the wrist and elbow. The breaking of the radius or ulna in the middle of the bone requires a strong force and it is most commonly seen in adults. In most of the cases, both bones are broken during a forearm fracture.

Forearms Fracture in Children

The radius (bone on the thumb side) and ulna (bone on the little-finger side) are the two bones of the forearm. Forearm fractures can occur near the wrist, near the elbow or in the middle of the forearm. Apart from this, the bones in children are prone to a unique injury known as a growth plate fracture. The growth plate, which is made of cartilage (flexible tissue) is present at the ends of the bones in children and helps in the determination of length and shape of the mature bone.

Distal Humerus Fractures of the Elbow

The elbow is a region between the upper arm and the fore arm. The elbow joint is made up of 3 bones. The distal (lower) end of the humerus bone in the upper arm joins with the radius and ulna bones in the fore arm to form the elbow joint. The elbow joint is very important for the movement of your arms and for coordination of daily activities. Injury in the distal humerus can cause impairment in the function of the elbow 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.

Radial Head Fractures of the Elbow

The elbow is a junction between the forearm and the upper arm. The elbow joint is made up of 3 bones namely the humerus bone in the upper arm which joins with the radius and ulna bones in the forearm. The elbow joint is essential for the movement of your arms and to perform daily activities. The head of the radius bone is cup-shaped and corresponds to the spherical surface of the humerus. The injury in the head of the radius causes impairment in the function of the elbow.

Glenoid Fractures

The glenoid is the socket that forms the ball and socket joint of the shoulder. Fractures of the glenoid are rare but can occur due to major trauma or during high-energy sports activities.

Baseball and Shoulder Injuries

Shoulder injuries in baseball players are usually associated with pitching. While this overhand throwing activity can produce great speed and distance for the ball, when performed repeatedly, it can place a lot of stress on the shoulder.

Elbow Fractures

Three bones, the humerus, radius and ulna, make up the elbow joint. Elbow fractures may occur from trauma, resulting from various reasons; some of them being a fall on an outstretched arm, a direct blow to the elbow, or an abnormal twist to the joint beyond its functional limit.

Procedures

Shoulder Injections

Ultrasound is a common imaging technique that employs high frequency sound waves to create images of organs and other internal structures of the body. These images provide valuable information of underlying pathology of the tissues and assists with diagnosis and planning the treatment of a condition. Ultrasound provides a clear view of the organs, tendons, muscles or joints and any associated disorders.

Arthroscopic Bankart Repair

The shoulder joint (glenohumeral joint) is a ball and socket joint, where the head of the upper arm bone (humerus) attaches to the shoulder socket (glenoid cavity). The shoulder socket is extremely shallow and therefore needs additional support to keep the shoulder bones from dislocating. The labrum, a cuff of cartilage that encircles the shoulder socket, helps serve this purpose by forming a cup for the humeral head to move within. It provides stability to the joint, enabling a wide range of movements.

Shoulder Labrum Reconstruction

The shoulder joint is a ball and socket joint. A 'ball' at the top of the upper arm bone (the humerus) fits neatly into a 'socket', called the glenoid, which is part of the shoulder blade (scapula). The labrum is a ring of fibrous cartilage surrounding the glenoid which helps in stabilizing the shoulder joint. The biceps tendon is attached inside the shoulder joint at the superior labrum of the joint. The biceps tendon is a long cord-like structure which attaches the biceps muscle to the shoulder and helps to stabilize the joint.

Shoulder Arthroscopy

Arthroscopy is a minimally invasive diagnostic and surgical procedure performed for joint problems. Shoulder arthroscopy is performed using a pencil-sized instrument called an Arthroscope. The arthroscope consists of a light system and camera to project images to a computer screen for your surgeon to view the surgical site. Arthroscopy is used to treat disease conditions and injuries involving the bones, cartilage, tendons, ligaments, and muscles of the shoulder joint.

Elbow Ligament Reconstruction

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, namely, radius and ulna. It is one of the important joints of the upper limb and is involved in basic movements such as flexion and extension of the upper limb and rotation of the forearm.

Elbow Tendon and Ligament Repair

The common conditions affecting the tendons around the elbow joint include tennis elbow and golfer’s elbow which result from an overuse injury to the tendons or result from repetitive activities such as sports, mechanical activities or weight lifting.

Elbow Contracture

Elbow contracture refers to a stiff elbow with limited range of motion. It is a common complication following elbow surgery, fractures, dislocations, and burns.

The normal functional range of motion for an elbow is 30-145 degrees. A stiff or contracted elbow may be diagnosed when the ability to extend or flex the arm is lessened by 30 degrees or more. Flexion contractures greater than 45 degrees will significantly affect the patient’s ability to perform activities of daily living such as bathing and eating.
