What is a Hand Tendon Laceration?
A hand tendon laceration is a deep cut or tear that damages the tendons in the hand. Tendons are strong, cord-like structures that connect muscles to bones, enabling movement of the fingers and wrist. When these tendons are lacerated, the ability to bend (flexor tendons) or straighten (extensor tendons) the fingers or thumb can be severely impaired. Tendon lacerations are serious injuries that often require surgical repair and rehabilitation to restore hand function.
Causes of Hand Tendon Lacerations
Tendon lacerations are typically caused by trauma that involves a sharp object. Common causes include:
- Glass cuts, especially from broken windows, bottles, or mirrors
- Knife injuries, either accidental or during food preparation
- Workplace accidents, particularly with power tools or industrial equipment
- Animal bites, which can penetrate deep enough to injure tendons
- Sports injuries, especially in contact sports or extreme activities
What are the Symptoms of a Hand Tendon Laceration?
Hand tendon lacerations usually present with clear functional symptoms. Watch for:
- Inability to bend or straighten a finger or thumb
- Visible tendon ends or open wound with exposed tissue
- Pain when trying to move the affected finger
- Numbness or tingling, if nearby nerves are also injured
- Swelling and bruising
- Deformity or unusual finger position, such as a finger that remains bent or limp
How is a Hand Tendon Laceration Diagnosed?
Diagnosis involves a careful clinical examination and often imaging:
- Physical exam, checking active and passive finger motion, grip strength, and sensation
- X-rays, to rule out associated bone injuries or foreign objects
- Ultrasound or MRI, occasionally used to assess tendon damage if not visible
What are the Treatment Options for a Hand Tendon Laceration?
Treatment often involves surgery and rehabilitation:
- Surgical repair, typically performed soon after injury, to reconnect the severed tendon ends
- Splinting, to protect the repair during early healing
- Physical therapy, beginning in stages to restore motion, strength, and flexibility
- Wound care and possible antibiotics, especially in cases with contamination or bite injuries
