Common Causes of Repetitive Stress Hand Injuries
Repetitive stress injuries stem from prolonged movements that strain the muscles, tendons, and joints in the hand and wrist. Key contributors include:
- Typing or Using a Computer Mouse: These activities can trigger carpal tunnel syndrome, tendinitis, and trigger finger.
- Repetitive Manual Labor: Assembly line work, construction, and gardening all involve hand movements that can cause RSIs.
- Sports and Hobbies: Musical instruments, knitting, and power tools put strain on hands and wrists.
- Poor Ergonomics: Awkwardly designed workstations and tools force hands into problematic positions.
- Underlying Medical Conditions: Arthritis, diabetes, and thyroid disorders increase RSI susceptibility.
Symptoms of Repetitive Stress Hand Injuries
Watch for these warning signs:
- Pain: Dull, aching, or sharp discomfort in hand, wrist, or forearm that worsens with activity
- Numbness and Tingling: Pins and needles sensations in fingers or hand
- Weakness: Reduced grip strength and difficulty with everyday tasks
- Swelling: Visible inflammation in hand, wrist, or fingers
- Stiffness: Limited range of motion when bending or straightening fingers
How Surgery Can Help
When conservative treatments fail, surgical options include:
- Carpal Tunnel Release: Relieves median nerve pressure
- Tendon Repair or Transfer: Addresses trigger finger and similar conditions
- Joint Replacement or Fusion: Alleviates severe arthritis damage
- Nerve Decompression: Relieves nerve entrapment symptoms
