Wrist & Thumb Injury

Wrist & Thumb Injury

Wrist and thumb sprains

  • Are also common, particularly in sports like skiing, where it’s not unusual to fall and land on an outstretched palm.
  • Spraining your wrist means that you have damaged one of the ligaments in the wrist, usually by bending or forcing it out of place
  • The severity of a sprain is usually graded according to the injury:
  • Grade 1 sprains are when the ligament is stretched rather than torn
  • Grade 2 sprains can involve a ligament being partly torn, which can affect your range of movement
  • Grade 3 sprains are when the ligament is torn, sometimes fracturing the bone as it tears (avulsion fracture).
  • Some wrist ligament tears can cause long term instability of the wrist and ultimately arthritis.

Causes

Wrist sprains are often caused by falling onto an outstretched hand for example when ice skating or during contact sports such as football or rugby.

Symptoms

  • These include pain, swelling, bruising, and tenderness
  • It’s important to see a doctor as soon as possible to avoid long term problems including limited movement

Diagnosis

  • After a discussion of how the injury happened,
  • Doctor examine your wrist
  • Confirm the diagnosis with X-rays to see if any bones are broken, and possibly an MRI or CT scan to assess damage to the ligaments

Treatment

  • Applying ice (crushed in a towel) several times a day.
  • Resting the wrist and elevating it (raising it above the heart) can help.
  • Taking anti-inflammatory medication if advised by your doctor.
  • Non-operative treatment:this includes
    • Wearing a splint or elasticated bandage
    • Gently exercising the wrist to help build strength and flexibility.
  • Surgery: you recover (this usually takes around six weeks)
    • if you have had a Grade 3 sprain
    • you may need surgery to reconnect the ligament to the bone.
    • Some ligament tears are crucial to detect and repair early, otherwise late damage and arthritis can develop. Afterwards you will usually be given exercises to rebuild strength and increase your range of movement while

Sprained Thumb

  • Sprained thumb occurs when the ligaments that support the thumb stretch beyond their limits or tear.
  • This usually happens when a strong force bends the thumb backwards, away from the palm of the hand.
  • The most common way for this to occur is by falling onto an outstretched hand.
  • Most thumb sprains involve the ulnar collateral ligament, which is located on the inside of the knuckle joint.
  • A tear to this ligament can be painful and may make your thumb feel unstable. It may also weaken your ability to grasp objects between your thumb and index finger.
  • Treatment for a sprained thumb usually involves wearing a splint or cast to keep the thumb from moving while the ligament heals. For more severe sprains, surgery may be needed to restore stability to the joint.
