Extensor Tendon Injuries in Texas Workers’ Compensation Claims
Extensor tendon injuries are common in Texas workers’ compensation claims — especially in construction, warehousing, manufacturing, oil field work, transportation, and any job requiring lifting, gripping, pushing, pulling, or tool use. These tendons allow workers to straighten their fingers, lift objects, release grip, and stabilize the wrist.
When injured, workers often experience pain, weakness, loss of motion, deformity, and difficulty performing essential job tasks. Insurance carriers frequently dispute extensor tendon injuries, calling them “minor,” “degenerative,” or “not work‑related.”
This post explains how extensor tendon injuries occur, how they’re diagnosed, what treatment is available, and how injured workers can protect their claims.
What Are Extensor Tendon Injuries?
Extensor tendons run along the back of the hand and fingers, allowing the fingers and wrist to straighten. Each finger has:
- Extensor Digitorum Communis (EDC) — extends the fingers
- Extensor Indicis Proprius (EIP) — extends the index finger
- Extensor Digiti Minimi (EDM) — extends the small finger
The thumb has:
- Extensor Pollicis Longus (EPL)
- Extensor Pollicis Brevis (EPB)
These tendons are thin, close to the skin, and easily injured by trauma, lacerations, or overuse.
Common Work Related Causes of Extensor Tendon Injuries
Extensor tendon injuries are strongly associated with:
- Machinery accidents
- Crush injuries
- Lacerations from tools or equipment
- Sudden pulling injuries
- Heavy lifting
- Repetitive gripping or releasing
- Tool vibration
- Working in tight or confined spaces
- Falls onto the hand
- Direct blows to the back of the hand
These mechanisms are fully consistent with compensable injuries under Texas workers’ compensation.
Types of Extensor Tendon Injuries
Below are the most common extensor tendon injuries — each with a Guided Link so you can build out the cluster.
Extensor Tendon Lacerations
Often caused by sharp tools, machinery, or glass.
See Extensor Tendon Lacerations.
Extensor Tendon Ruptures
Tendon tears from sudden force or trauma.
See Extensor Tendon Ruptures.
Mallet Finger (Terminal Extensor Tendon Injury)
Inability to straighten the fingertip.
See Mallet Finger.
Boutonnière Deformity (Central Slip Injury)
Inability to straighten the middle joint.
See Boutonnière Deformity.
Sagittal Band Rupture (“Boxer’s Knuckle”)
Extensor tendon slips off the knuckle.
See Sagittal Band Rupture.
Symptoms of Extensor Tendon Injuries
Workers often report:
- Pain on the back of the hand or fingers
- Difficulty straightening the fingers
- Drooping fingertip or knuckle
- Clicking or catching
- Weak grip strength
- Swelling
- Bruising
- Finger deformity
- Loss of range of motion
Symptoms may appear immediately after trauma or worsen over time.
Diagnosis of Extensor Tendon Injuries
Diagnosis may include:
- Physical Examination
- Ultrasound (excellent for tendon tears)
- MRI (useful for complex or disputed cases)
- X‑ray (rules out fractures or avulsion injuries)
- Nerve conduction studies (if nerve injury suspected)
Accurate diagnosis is essential for proving causation and securing treatment.
Medical Treatment for Extensor Tendon Injuries
Workers may be entitled to:
Conservative Care (for mild injuries) Splinting Anti‑inflammatory medications Activity modification Hand therapy
Injections Corticosteroid injections (for tendon sheath inflammation)
Surgery For moderate to severe injuries:
- Tendon repair
- Tendon reconstruction
- Sagittal band repair
- Central slip repair
- Debridement
- Fixation for avulsion fractures
Post‑Operative Rehabilitation Hand therapy Range‑of‑motion work Strengthening
Functional Restoration Programs
Recovery Timeline
Typical recovery:
- Mild tendonitis: 2–6 weeks
- Tendon lacerations: 6–10 weeks
- Tendon ruptures: 3–6 months
- Post‑surgical recovery: 3–6 months
Workers performing heavy labor may require extended restrictions.
Complications of Extensor Tendon Injuries
If untreated or undertreated, extensor tendon injuries can lead to:
- Chronic pain
- Loss of finger extension
- Grip weakness
- Finger deformity
- Tendon adhesions
- Post‑traumatic arthritis
- Permanent impairment
These complications often increase impairment ratings.
Impairment Ratings for Extensor Tendon Injuries
Impairment ratings may be based on:
- Loss of finger motion
- Grip strength deficits
- Tendon rupture
- Surgical outcomes
- Chronic pain
- Functional limitations
Extensor tendon injuries frequently result in measurable impairment.
Why Insurance Companies Dispute Extensor 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:
