Flexor Tendon Injuries in Texas Workers’ Compensation Claims

Flexor tendon injuries are among the most serious and function‑limiting hand injuries seen in Texas workers’ compensation claims. Our flexor tendons allow us to grip tools, lift objects, make a fist, and perform nearly every essential hand movement. When injured, workers often experience pain, weakness, loss of motion, and difficulty performing job tasks.

Insurance carriers frequently dispute flexor tendon injuries, calling them “minor,” “degenerative,” or “not work‑related.” This post explains how flexor tendon injuries occur, how they’re diagnosed, what treatment is available, and how injured workers can protect their claims.

What Are Flexor Tendon Injuries?

Flexor tendons run from the forearm into the palm and fingers, allowing the fingers to bend. Each finger has two flexor tendons:

  • Flexor Digitorum Profundus (FDP) — bends the fingertip
  • Flexor Digitorum Superficialis (FDS) — bends the middle joint


The thumb has one:

  • Flexor Pollicis Longus (FPL)


Flexor tendons travel through narrow tunnels called pulleys, which keep them close to the bone. Injury to these tendons can cause:

  • Pain
  • Loss of finger flexion
  • Inability to grip
  • Clicking or catching
  • Weakness
  • Permanent disability if untreated


See Hand & Finger Injuries.

Common Work Related Causes of Flexor Tendon Injuries

Flexor tendon injuries are strongly associated with:

  • Machinery accidents
  • Crush injuries
  • Lacerations from tools or equipment
  • Sudden pulling injuries
  • Heavy lifting
  • Repetitive gripping
  • Tool vibration
  • Working in tight or confined spaces
  • Falls onto the hand


These mechanisms are fully consistent with compensable injuries under Texas workers’ compensation.

Types of Flexor Tendon Injuries

Below are the most common flexor tendon injuries — each with a Guided Link so you can build out the cluster.

1. Flexor Tendon Lacerations

Often caused by sharp tools, machinery, or glass.

See Flexor Tendon Lacerations.

2. Flexor Tendon Ruptures

Tendon tears from sudden force or trauma.

See Flexor Tendon Ruptures.

3. Jersey Finger (FDP Avulsion)

The FDP tendon pulls off the bone — common in gripping injuries.

See Jersey Finger.

4. Trigger Finger (Stenosing Tenosynovitis)

Inflamed tendon sheath causes painful catching or locking.

See Trigger Finger.

5. Flexor Tendon Adhesions

Scar tissue restricts tendon movement after injury or surgery.

See Flexor Tendon Adhesions.

Symptoms of Flexor Tendon Injuries

Workers often report:

  • Pain in the palm or fingers
  • Difficulty making a fist
  • Inability to bend one or more joints
  • Clicking or catching
  • Weak grip strength
  • Swelling
  • Numbness or tingling (if nerves are involved)
  • Finger deformity


Symptoms may appear immediately after trauma or worsen over time.

Diagnosis of Flexor Tendon Injuries

Diagnosis may include:

  • Physical Examination
  • Ultrasound (excellent for tendon tears)
  • MRI (useful for complex or disputed cases)
  • X‑ray (rules out fractures)
  • Nerve conduction studies (if nerve injury suspected)


Accurate diagnosis is essential for proving causation and securing treatment.

Medical Treatment for Flexor Tendon Injuries

Workers may be entitled to:

Conservative Care (for mild inflammation) Anti‑inflammatory medications Splinting Activity modification Physical therapy

Injections Corticosteroid injections (for trigger finger)

Surgery For moderate to severe injuries:

  • Tendon repair
  • Tendon reconstruction
  • Pulley repair
  • Debridement
  • Release procedures (trigger finger)
  • Nerve repair (if injured)


Post‑Operative Rehabilitation Hand therapy Range‑of‑motion work Strengthening

Recovery Timeline

Typical recovery:

  • Mild tendonitis: 2–6 weeks
  • Tendon lacerations: 8–12 weeks
  • Tendon ruptures: 3–6 months
  • Post‑surgical recovery: 3–6 months


Workers performing heavy labor may require extended restrictions.

Complications of Flexor Tendon Injuries

If untreated or undertreated, flexor tendon injuries can lead to:

  • Chronic pain
  • Loss of finger motion
  • Grip weakness
  • Tendon adhesions
  • Finger deformity
  • Post‑traumatic arthritis
  • Permanent impairment


These complications often increase impairment ratings.

Impairment Ratings for Flexor Tendon Injuries

Impairment ratings may be based on:

  • Loss of finger motion
  • Grip strength deficits
  • Tendon rupture
  • Surgical outcomes
  • Chronic pain
  • Functional limitations


Flexor tendon injuries frequently result in measurable impairment.

Why Insurance Companies Dispute Flexor Tendon Injuries

Carriers often argue:

  • The injury is “degenerative”
  • Symptoms are “intermittent”
  • The mechanism was “insufficient”
  • The worker had prior hand pain
  • Nerve symptoms are “unrelated”
  • The condition is “not work‑related”


These disputes can be challenged through:
