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
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 or breaks in the wrist are the most frequent fractures seen in the emergency room. view
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
The scaphoid is the most frequently fractured (broken) carpal bone in the wrist. view
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
Open wrist wounds indicate the skin is breached, the wound contaminated and exposure with potential injury of deeper structures is a possibility. view
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
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 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 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
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
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
Infections about the wrist are diseases caused by micro-organisms that invade tissue and cause destruction with the consequent loss of function. view
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
Trauma is the term for injury to the body from an external source. Severity of trauma is classified by the amount of force used to cause the injury. Trauma can be caused by a single major force or minor repetitive, smaller forces over time (Cumulative Trauma Disorder (CTD)).
Other injury classifying features:
Minor injuries, where soft tissue is bruised or stretched, but not torn are called a “contusion.” A contusion means the injury was closed and requires only symptomatic treatment of the soft tissues (alone of in combination) such as:
The same force of trauma sustained by different patients will result in different injury severity because of changes occurring in our body’s internal structure with aging.
Below is a graph divided into 20- year increments depicting an identical force sustained by individuals at different ages. It compares the time it takes for each group to heal and become symptom-free. The white section is when the patient is symptom-free and the yellow section is when the patient has symptoms including pain, stiffness, weakness, and poor function. Note, the curve does not come back to baseline and shifts to the right with aging.
There are three common approaches to symptomatic treatment for all types of soft tissue injuries:
The stages of R.I.C.E. are used to treat injuries such as a strain (muscle injury) and a spring (a ligament stretch injury).
The Rest stage is usually done for 24-48 hours and can include the use of slings, splints or other types of immobilizers unless otherwise advised by a physician.
The Ice stage is used for no more than 20-30 minutes, three to four times per day. Icing treatment functions by causing the arteries to narrow the size of their lumen, which in turn decreases swelling and the pain from the subsequent increased pressure. Ice treatment is best applied by using an ice slush. Ice slush is made by mixing crushed ice with water in a bag. The ice bag should not be placed in direct contact with the skin but instead use a buffer layer between the skin and ice bag like a towel to prevent skin freezing.
The Compression stage is the wrapping of a body part to further assist in minimizing swelling and is used in conjunction with elevation. The best compressive wrapping has multiple layers providing a cushion effect. The compression wrapping should not cause constriction of the blood supply. Constriction is recognized by increasing pain to the body part wrapped. Other signs of a tight compressive dressing are:
The Elevation stage of treatment is best done by elevating the limb to the level of the heart. If elevation is lower than this, the effects of gravity on the veins will increase vein pressure and cause the blood to have difficulty traveling back to the heart. This can result in limb swelling.
The use of anti-inflammatory medication helps treat the pain, swelling, and inflammation occurring after injury.
Examples of anti-inflammatories include:
All of these medications have side effects and should be taken with this knowledge in mind. Prescriptions should be discussed with your pharmacist and physician.
Controlled early motion and therapy to the involved limb decreases the effects of prolonged immobilization. Prolonged immobilization results in stiffness, muscle atrophy, weakness and also shortens the time to return to the pre-injury state.
The type of therapy recommended will depend on the type of tissue injured and the severity of the injury. Consult your surgeon for the best advice.
When treating a wrist contusion, a sling can provide comfort but is not ideal for wrist injuries as it frequently places the hand below the level of the heart when in the seating or standing position. This can worsen swelling, inflammation and the resultant throbbing pain. Therefore, it is preferable not to use a sling but instead to actively elevate the hand above heart level, like when doing the pledge of allegiance, with modifications of this position depending on body position. Carrying a pillow with you may assist in positioning of the hand.
Mobilization of shoulder and elbow should be included in the recovery program to prevent stiffness of the joints.
The home exercise program given to the wrist is referred to as the Six Pack Hand program and is provided below.
The program is progressed from exercise one through six. The wrist should be mobilized early with the assistance of the contralateral uninjured hand. Placing the wrist in the praying position and in the opposite direction is helpful in preventing stiffness. Exercises like throwing a dart facilitate a gentle –ergonomic exercise for the wrist.
