Hand and Wrist

Normal Hand Anatomy

The hand in the human body is made up of the wrist, palm, and fingers. The most flexible part of the human skeleton, the hand enables us to perform many of our daily activities. When our hand and wrist are not functioning properly, daily activities such as driving a car, bathing, and cooking can become impossible.

Elbow Dislocation

Elbow dislocation occurs when the humerus comes out of alignment with the bones of the forearm, the ulna and radius. Elbow dislocations are the second most common joint dislocation, other than shoulder dislocations, and are the most common joint dislocations in children.

Trigger Finger

The ability to bend the fingers is governed by supportive tendons that connect muscles to the bones of the fingers. The tendons run along the length of the bone and are kept in place at intervals by tunnels of ligaments called pulleys. When the fingers bend or are straightened, a slippery coating called tenosynovium helps the tendons smoothly glide through the ligaments with reduced friction.

Dupuytren’s Contracture

Dupuytren’s Contracture is a hand condition where thickening of the underlying fibrous tissues of the palm cause the fingers to bend inward. Patients with this condition are unable to fully straighten the affected fingers.

De Quervain’s Tenosynovitis

The muscles and bones of the hand are connected by thick flexible tissue called tendons. Tendons are covered by a thin soft sheath of tissue known as synovium. Extensor pollicis brevis and abductor pollicis longus are two tendons located on the thumb side of the wrist. Inflammation and swelling of the tendon sheaths puts pressure on the adjacent nerves and leads to pain and numbness in the thumb side of the wrist.

Hand Surgery

The hand is considered one of the most complex structures in the human body due to its intricate anatomy. Your hands are a complex system of various bones, joints, ligaments, tendons, muscles, nerves and blood vessels. Without the healthy functioning of the hand we are unable to perform activities of daily living.

Carpal Tunnel Syndrome

Carpal Tunnel Syndrome is a common, painful, progressive condition that is caused by compression of the median nerve at the wrist area.

Wrist Fracture

The wrist is comprised of two bones in the forearm, the radius and ulna, and eight tiny carpal bones in the palm. The bones meet to form multiple large and small joints. A wrist fracture refers to a break in one or more of these bones.

Arthroscopic Wrist Surgery

Your wrist is a complex joint made up of eight small bones called carpal bones. These bones are supported by connecting ligaments. Various conditions can affect your wrist joint such as carpal tunnel syndrome, osteoarthritis and others. Wrist arthroscopy is a minimally invasive surgical procedure performed to view, diagnose, and treat problems of your wrist joint.

Wrist Joint Replacement

Wrist joint replacement surgery, also referred to as total wrist arthroplasty, involves replacement of a severe arthritic wrist joint with an artificial joint made of metal and plastic components. It relieves pain and restores function when conservative treatment fails to provide relief.

Distal Triceps Tendon Rupture

Distal triceps rupture (or complete tear) occurs when the triceps tendon detaches from its attachment point on the olecranon process of the ulna resulting in partial or complete weakness of elbow extension. This injury is rare, with an incidence rate of 0.8%, and generally occurs between 30 to 50 years of age with a higher incidence in males. Risk factors for sustaining a distal triceps tendon rupture injury include chronic kidney disease (CKD) with dialysis, rheumatoid arthritis, systemic lupus erythematous, diabetes, Marfan’s syndrome, osteogenesis imperfecta, and hyperparathyroidism, chronic olecranon bursitis, and elbow arthroplasty. Nonetheless, sometimes the injury occurs simply as a result of trauma.
