Lunotriquetral Ligament Tears in Texas Workers’ Compensation Claims
Lunotriquetral ligament (LTL) tears are serious wrist injuries frequently seen in Texas workers’ compensation claims — but they are far less recognized than scapholunate ligament tears. The lunotriquetral ligament stabilizes the connection between the lunate and triquetrum, two critical carpal bones on the ulnar side of the wrist. When torn, the wrist becomes unstable, painful, and mechanically dysfunctional.
Because LTL tears often require surgery and can lead to long‑term disability or arthritis, insurance companies frequently dispute them, claiming the injury is “degenerative,” “minor,” or “not work‑related.” This post explains how lunotriquetral ligament tears happen, how they’re diagnosed, what treatment is available, and how injured workers can protect their claims.
Understanding the Lunotriquetral Ligament
The lunotriquetral ligament connects:
- Lunate (central carpal bone)
- Triquetrum (ulnar‑side carpal bone)
It provides:
- Ulnar‑sided wrist stability
- Proper carpal alignment
- Smooth flexion/extension
- Load distribution during gripping and lifting
When torn, the lunate and triquetrum move abnormally — a condition known as lunotriquetral instability.
Common Work Related Causes of Lunotriquetral Ligament Tears
LTL tears are strongly associated with:
- Falls onto an outstretched hand (FOOSH)
- Heavy lifting
- Forceful twisting (tools, machinery, torqueing)
- Sudden pulling injuries
- Direct blows to the wrist
- High‑impact trauma
- Repetitive strain in manual labor
These mechanisms are fully consistent with compensable injuries under Texas workers’ compensation.
Symptoms of Lunotriquetral Ligament Tears
Workers often report:
- Ulnar‑sided wrist pain
- Clicking or popping
- Weak grip strength
- Pain with lifting or twisting
- Swelling
- Instability
- Difficulty bearing weight through the wrist
Symptoms may appear immediately after trauma or worsen over time.
Types of Lunotriquetral Ligament Injuries
- Partial Tear Some fibers torn; instability may be mild.
- Complete Tear Full rupture; significant instability.
- Lunotriquetral Instability Abnormal motion between lunate and triquetrum.
- Midcarpal Instability Advanced instability affecting multiple carpal joints.
- Post‑Traumatic Arthritis Long‑term consequence of untreated LTL tears.
Diagnosis of Lunotriquetral Ligament Tears
Diagnosis may include:
- Physical Examination Ballottement test Pain with ulnar deviation Grip strength testing
- X‑ray May show carpal misalignment.
- MRI Identifies partial or complete ligament tears.
- MR Arthrogram Provides enhanced visualization of ligament integrity.
- CT Scan Useful for evaluating carpal alignment.
Accurate diagnosis is essential for proving causation and securing treatment.
Medical Treatment for Lunotriquetral Ligament Tears
Workers may be entitled to:
- Conservative Care (for mild partial tears) Anti‑inflammatory medications Bracing Physical therapy Activity modification
- Injections Steroid injections may reduce inflammation.
- Surgery (standard of care for moderate to severe tears) Lunotriquetral ligament repair Capsulodesis Tendon graft reconstruction Pinning or screw fixation Partial wrist fusion (advanced cases)
- Post‑Operative Rehabilitation Strengthening Range‑of‑motion work Gradual return to lifting
- Work Hardening
- Functional Restoration Programs
Recovery Timeline
Typical recovery:
- Partial tears: 6–12 weeks
- Complete tears: 3–6 months
- Postsurgical recovery: 6–12 months
Workers performing heavy labor may require extended restrictions.
Complications of Lunotriquetral Ligament Tears
If untreated or undertreated, LTL tears can lead to:
- Chronic instability
- Grip weakness
- Persistent pain
- Midcarpal instability
- Post‑traumatic arthritis
- Permanent impairment
These complications often increase impairment ratings.
Impairment Ratings for Lunotriquetral Ligament Tears
Impairment ratings may be based on:
- Loss of wrist motion
- Grip strength deficits
- Instability
- Surgical outcomes
- Chronic pain
- Post‑traumatic arthritis
LTL tears frequently result in measurable impairment.
Why Insurance Companies Dispute Lunotriquetral Ligament Tears
Carriers often argue:
- The tear is “degenerative”
- The worker had prior wrist pain
- The mechanism was “insufficient”
- The MRI shows “wear‑and‑tear”
- The condition is “not work‑related”
These disputes can be challenged through:
