Hand Tendon Repair

Overview

• Surgery may be necessary to repair damaged tendons in the hand, which helps restore movement to the fingers or thumb.

What are Tendons?

• Tendons are tough tissue cords that connect muscles to bones.
• Muscle contractions pull tendons, facilitating movement.
• Two groups of tendons in the hand:
  • Extensor tendons: Run from forearm, across hand back to fingers/thumb; enable straightening.
  • Flexor tendons: Run from forearm, through wrist, across palm; enable bending.
• Surgery can repair both types of tendons.

When Hand Tendon Repair is Needed

• Necessary when tendons rupture or are cut, impairing hand movement.
  • Extensor damage: Inability to straighten fingers.
  • Flexor damage: Inability to bend fingers.
• Tendon damage causes pain and swelling.
• Some extensor tendon issues treated with a splint, not surgery.
• Injury Causes:
  • Cuts, sports injuries, bites, crushing injuries, rheumatoid arthritis.

Tendon Repair Surgery

• Involves incision in wrist, hand, or finger to locate and stitch tendon ends.
• Extensor tendons are easier to repair due to accessibility.
• Detailed surgery process available on NHS website.

Recovering from Surgery

• Long recovery period required, as tendons are weak until healed.
• Full strength recovery takes up to 3 months.
• Rehabilitation includes wearing a splint and performing hand exercises.
• Return to work varies:
  • Light activities: 6-8 weeks post-surgery.
  • Heavy activities/sport: 10-12 weeks post-surgery.
• More info on recovery available on NHS website.

Results

• Post-extensor repair: Functional but potentially limited movement.
• Outcome better with clean cuts rather than crush injuries.
• Flexor tendon injuries are more severe; full movement recovery less likely.
• Tendon repair still offers better results than no surgery.
• Potential complications: infection, snapping, sticking of tendon. Further treatment may be needed.
