WRIST

Wrist Anatomy

The wrist is a bio-mechanically complex joint allowing the wrist to move in extension (up), flexion (down), radial deviation (towards the thumb), ulnar deviation (towards the small finger) and minimal degrees of rotation. view 

Wrist Contusion

Trauma is the term used to describe injury. Trauma is classified by its severity depending on the amount of force used to cause the injury. view 

Wrist Fractures

Wrist Fractures or breaks in the wrist are the most frequent fractures seen in the emergency room. view 

Distal Ulnar Fractures and Traumatic Injuries

The distal end of the ulna is rarely fractured(broken) in isolation except when direct trauma like a gunshot wound or a direct blow to the ulna occurs when the arm is elevated to protect the face. view 

Scaphoid Fractures

The scaphoid is the most frequently fractured (broken) carpal bone in the wrist. view

Wrist Dislocations / Fracture Dislocation

Dislocations of the wrist are rare injuries frequently associated with high energy trauma like a fall from a height, a motor vehicle collision or a high impact sporting event. view

Wrist Open Wounds

Open wrist wounds indicate the skin is breached, the wound contaminated and exposure with potential injury of deeper structures is a possibility. view

Wrist Amputations

An amputation is the severing of a body part. Amputations are classified as partial and complete and if the amputation was a clean cut, a crushing amputation or an avulsion amputation where the amputated limb is pulled right off of the body. view

Wrist Arthritis

The primary vessels or channels that supply blood to the hand while traveling across the wrist are the Radial and Ulnar Arteries. view

Carpal Tunnel Syndrome

Carpal tunnel syndrome is the most frequent cause of nerve compression in the human body. It is caused by compression of the median nerve at the level of the wrist. view

Ulnar Tunnel Syndrome

Ulnar Tunnel Syndrome is the compression of the ulnar nerve at the level of the wrist. Similar to the median nerve, this nerve can be compressed at more proximal locations and can occur in combination with other nerves. view

Wrist Tendonitis

Tendonitis is swelling or inflammation of the tendon or tendon lining called tenosynovium. Tendons at the wrist are normally confined to tunnels they travel through. view

Stiff Wrist

After injury, patients can develop decrease range of motion as a consequence of swelling, pain, and scar formation occurring with significant adhesions that bind various tissue layers. view

Wrist Infections

Infections about the wrist are diseases caused by micro-organisms that invade tissue and cause destruction with the consequent loss of function. view

Wrist Tumors

The most frequent cause of swelling or masses found at the wrist level is ganglion cysts. More frequently found in women, ganglions are like a little balloon made out of the joint capsule, filled with a clear, colorless, gelatinous fluid that comes from the joint itself. view

ULNAR TUNNEL SYNDROME

Ulnar Tunnel Syndrome is the compression of the ulnar nerve at the level of the wrist. Similar to the median nerve, this nerve can be compressed at more proximal locations and can occur in combination with other nerves. It is the job of the hand specialist to identify and differentiate the location and severity of the compression. During the ulnar nerve’s path to the hand, it is accompanied by the ulnar artery and together they crossa fibro-osseous tunnel named, Guyon’s canal. It is in this location that the nerve may be entrapped. Ulnar Tunnel Syndrome is much less frequent than carpal tunnel and cubital tunnel syndrome. Unlike carpal tunnel syndrome, the ulnar tunnel syndrome is frequently caused by an occupying mass or trauma including a ganglion cyst, lipoma, ulnar artery thrombosis, aneurysm, hook of the hamate fracture or distal radius fracture. Patients can complain of pain, numbness and tingling of the pinky and ring fingers, loss of dexterity, weakness, clawing position of the ring and small fingers while attempting a straighten the fingers and signs of decreased or absent blood supply to the same digits. A careful history and physical exam should provide the correct diagnosis. Confirmation of the diagnosis can be done with electro diagnostic studies. Non-operative treatment has minimal role in this condition. Once the diagnosis is confirmed, surgical exploration and treatment is necessary according to the causative factor. Details of the surgical plan are explained at the ROC by your surgeon with contingency plans included depending on what is discovered during surgery.
