Understanding Tendon Injuries
Tendons are strong, fibrous tissues connecting muscles to bones and enabling movement. In the hand and wrist, they facilitate gripping, pinching, and fine motor activities. Common injuries include:
- Tendonitis: Inflammation from overuse or strain
- Tendon lacerations: Cuts or tears from sharp objects or accidents
- Trigger finger: A condition where a finger gets stuck bent due to inflamed tendons
- De Quervain’s Tenosynovitis: Inflammation of tendons at the thumb’s base, often from repetitive hand movements
Preventing Tendon Injuries
1. Practice Proper Ergonomics
Set up your workstation correctly if your job involves repetitive hand motions like typing. Maintain a neutral wrist position and use ergonomic keyboards, wrist supports, or tools designed to reduce strain.
2. Stretch and Strengthen
Regular exercises maintain flexibility and improve tendon resilience. Simple wrist stretches and grip-strengthening exercises keep tendons supple and strong.
3. Take Breaks and Avoid Overuse
Overuse causes many tendon injuries. Take regular breaks from repetitive hand movements and alternate tasks to reduce strain.
4. Use Proper Techniques
Whether lifting or playing sports, proper hand and wrist mechanics prevent strain. Avoid excessive force and awkward positions.
5. Wear Protective Gear
For high-risk activities like sports or construction, protective gloves or braces help prevent injuries.
Managing Tendon Injuries
Early intervention prevents long-term damage:
- Rest and Immobilization: Avoid aggravating activities; splints or braces limit movement and allow healing
- Apply Ice and Compression: Ice reduces inflammation and pain within 48 hours; compression bandages manage swelling
- Physical Therapy: Therapists guide exercises to restore movement, improve strength, and reduce stiffness
- Corticosteroid Injections: For persistent inflammation, injections reduce swelling and improve mobility
- Surgical Intervention: Severe cases like complete ruptures or deep lacerations may require surgical repair and rehabilitation
