Broken wrist/broken hand

Definition:
Broken wrist
A broken wrist or broken hand is a break or crack in one of the many bones within your wrist and hand. The most common of these injuries occurs in the wrist when people try to catch themselves during a fall and land hard on an outstretched hand.

Risk factors for a broken wrist or broken hand range from participation in certain sports — such as American football, soccer, skiing or snowboarding — to having osteoporosis, a condition in which bones become thinner and more fragile.
It's important to treat a broken wrist or broken hand as soon as possible. Otherwise, the bones may not heal in proper alignment, which can affect your ability to perform everyday activities, such as grasping a pen or buttoning a shirt. Early treatment will also help minimize pain and stiffness.

Symptoms:

If you have a broken wrist or broken hand, you may experience these signs and symptoms:
  • Severe pain that tends to increase during gripping or squeezing
  • Swelling
  • Tenderness
  • Bruising
  • Obvious deformity, such as a bent wrist or crooked finger
  • Stiffness or inability to move your fingers or thumb
  • Numbness or coldness in your hand
When to call a doctor
If you think you may have a broken wrist or hand, see a doctor immediately, especially if you have numbness, swelling or trouble moving your fingers. Delays in diagnosis and treatment can lead to poor healing, decreased range of motion and decreased grip strength.

Causes:

A direct blow or crushing injury to your hands and wrists can break any of the bones in them. Common causes include:
  • Falls. Falling onto an outstretched hand is one of the most common causes of a broken wrist or broken hand.
  • Sports injuries. Many wrist or hand fractures occur during contact sports or sports in which you might fall onto an outstretched hand — such as in-line skating or snowboarding. Finger fractures are common with baseball, basketball and football.
  • Motor vehicle crashes. High-velocity injuries that can occur during motor vehicle crashes may cause wrist or hand bones to fracture into many pieces, requiring surgical repair.
Complications:

Complications of a broken wrist or broken hand are rare, but they may include:
  • Ongoing stiffness, aching or disability. Stiffness, pain or aching in the affected area generally goes away a month or two after your cast is removed or after surgery, but you may have some permanent stiffness or aching if your injury was severe. It may also take a few months to regain your ability to use your hand and fingers normally. Be patient with your recovery, and talk to your doctor about exercises that might help or for a referral to physical or occupational therapy.
  • Osteoarthritis. Fractures that extend into the joint may cause arthritis years later. If your wrist or hand starts to hurt or swell long after a break, see your doctor for an evaluation.
  • Nerve or blood vessel damage. Trauma to the wrist or hand can injure adjacent nerves and blood vessels. Seek immediate attention if you notice any numbness or circulation problems
Treatments and drugs:

If the broken ends of the bone aren't aligned properly, your doctor will need to manipulate the pieces back into their proper positions — a process called fracture reduction. Depending on the amount of pain and swelling you have, you may need a muscle relaxant, a sedative or even a general anesthetic before this procedure.

Immobilization
Restricting the movement of a broken bone in your wrist or hand is critical to proper healing. To do this, you may need a splint or a cast.

Medications
To reduce pain and inflammation, your doctor may recommend an over-the-counter pain reliever, such as acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin, others). If you're experiencing severe pain, you may need an opioid medication, such as codeine.

Therapy
After your cast or splint is removed, you'll likely need rehabilitation exercises or physical therapy to reduce stiffness and restore movement in your wrist and hand. Rehabilitation can help, but it may take up to several months — or even longer — for complete healing of severe injuries.

Surgical and other procedures
Immobilization heals most broken bones. However, you may need surgery to implant internal fixation devices, such as plates, rods or screws, or bone grafts to maintain proper position of your bones during healing. These internal fixation devices may be necessary if you have the following injuries:
  • Multiple fractures
  • An unstable or displaced fracture
  • Loose bone fragments that could enter a joint
  • Damage to the surrounding ligaments
  • Fractures that extend into a joint
  • A fracture that is the result of a crushing accident
In some cases, the surgeon may immobilize your fracture by using an external fixation device. This consists of a metal frame with two or more pins that go through your skin and into the bone on either side of the fracture.
