How to Treat Strained or Torn Extensor Tendon Insertion

A tendon is a corded band of tissue connecting muscles to bones. The extensor tendons, located on the back of the hand, connect the bones of the fingers and thumb to the forearm and make it possible to straighten the fingers. A strain, or damage to the muscles or tendons, often results in tearing of the extensor tendon. This can result in pain, inflammation and dysfunction of the hand. Treatment for a strained or torn extensor tendon is important to decrease the chances of chronic problems of the hand and fingers.

Instructions

Strained or Torn Extensor Tendon – The First 48 Hours

• 1

  Halt all activities involving injured hand.

• 2

  Apply towel-wrapped ice pack to area of injury, pain and inflammation, or swelling. Use ice in twenty minute intervals for 2 to 4 hours.

• 3

  Wrap the area with an ace wrap to decrease swelling. Apply ace wrap starting at the fingers and working up the hand to the wrist in a diagonal fashion to limit hand movement. If numbness, tingling or discoloration of the fingers occurs, remove wrap immediately.

  Elevate hand and forearm by resting on pillow, optimally above the level of the heart to minimize swelling.

  Consult with primary physician to assess severity of injury, help alleviate pain and prevent future hand dysfunction.

Strained or Torn Extensor Tendon – After the First 48 Hours

• 6

  Begin gentle range of motion exercises to wrist, hand and fingers. Flex and extend, or bend and straighten wrist. Flex fingers by making a fist, then extend the fingers. Movements should be within pain tolerance. If increased pain is experienced decrease amount of movement. If pain continues, consult with primary physician.

• 7

  Apply moist heating pad to area for fifteen minutes after range of motion or when experiencing increased pain. If heat increases pain and swelling, resume ice pack.

• 8

  Consult with a physical therapist for pain-relieving modalities and exercises. Modalities can include ultrasound, a deep form of heat delivered via sound waves, and electrical stimulation, an electrical form of pain relief which can strengthen weak muscles and promote healing. Exercises can include range of motion and wrist, hand and finger strengthening

• 9

  Perform physical therapy-directed range of motion and strengthening exercises at home as directed.

• 10

  Resume normal activities within tolerance. If pain persists or increases, halt activity and consult with primary physician to rule out any complications with strained or torn extensor tendon injury.
