Hand and Wrist Injuries

Hand

 

Osteoarthritis in the Hand

Osteoarthritis in the finger happens when the protective cushioning between the joints wear out. Inflammation occurs in the finger joints due to wear and tear. The bones rub directly against other bones, causing structural changes. Bone deposits or bone spurs may develop on the edges of the joints. The soft tissues that stabilize joints may also show signs of wear. The joint cartilages declines and worsens steadily. Joint instability and misalignment can also occur as a result of osteoarthritis. Heavy usage and traumatic injuries that result in joint irregularities are some risk factors involved.

Osteoarthritis in the hand occurs in a few places. The wrist, the joint located at the base of the thumb, the joint at the end of the finger closest to the nail and the joint in the middle of the finger are all areas where osteoarthritis can occur.

Osteoarthritis in the Hand

Symptoms

  • Bumps or bony knobs around the arthritic site.
  • A grinding, crunchy feeling when joints move
  • Less range of motion in affected joints
  • Joint pain
  • Joint stiffness
  • Swelling

 

Trigger Finger

Trigger Finger occurs when one of your fingers or your thumb gets stuck in a bent position and then straightens with a snap — like a trigger being pulled and released. If trigger finger is severe, your finger may become locked in a bent position. Trigger fingers may occur after activities that strain the hand. It’s caused by a narrowing of the sheath that surrounds the tendon in the affected finger. People whose work or hobbies require repetitive gripping actions are more vulnerable. Trigger finger is also more common in women and in anyone with diabetes.

Trigger Finger

Symptoms

  • Swelling
  • Tender lump in your palm
  • Pain bending or straightening finger
  • Catching or popping sensation
  • Stiffness and tenderness


Boxer’s Fracture

The name, Boxer’s fractures derive from one of their most common causes, punching an object with a closed fist. This occurs during fist fights or from punching a hard object such as a wall. Though these breaks usually occur when the hand is closed into a fist, they can also occur when the hand is not clenched or while it strikes a hard object.

Symptoms

  • Pain and tenderness
  • Snapping and popping sensation
  • Swelling
  • Discoloring or bruising
  • Misalignment of your fist.

 

Wrist

 

Carpal Tunnel Syndrome

Carpal Tunnel Syndrome is a common problem affecting the hand and wrist. The pain occurs when the median nerve gets squeezed inside the carpal tunnel of the wrist. Over the years, this syndrome has been linked with occupations that require repeated use of the hands, such as typing on a computer keyboard or doing assembly work. However, many people develop this condition regardless of the type of work they do. The area in your wrist where the nerve enters the hand is called the carpal tunnel. This tunnel is normally narrow, so any swelling can pinch the nerve and cause pain, numbness, tingling or weakness.

Carpal Tunnel Syndrome

Symptoms

  • Numbness or tingling in your thumb and next two or three fingers of one or both hands
  • Pain in wrist or hand in one or both hands
  • Weak grip
  • Numbness or tingling of the palm of your hand
  • Pain extending to the elbow
  • Problems with coordination in one or both hands

 

De Quervain’s Tendinitis (De Quervain’s Tendinosis)

De Quervain’s tendinitis is an inflammation of the tendons on the thumb side of the wrist. It occurs when the tendons around the base of the thumb swells. It’s caused when tendons on the thumb side of the wrist are swollen or irritated. The irritation causes the lining around the tendon to swell, making it difficult for the tendons to move as they should. It is also caused by overuse.

Carpal Tunnel Syndrome

Symptoms

  • Pain on the thumb side of the wrist.
  • Pain travelling up the forearm.
  • Swelling over the thumb side of the wrist.
  • Numbness on the back of the thumb and index finger.
