Trigger finger — medically known as stenosing flexor tenosynovitis — is a recognized repetitive stress injury under Missouri workers' compensation law. When your job requires repeated gripping, forceful hand movements, or prolonged finger flexion, the resulting inflammation can cause your finger to catch, lock, or snap — and you may be entitled to workers' compensation benefits for medical treatment, lost wages, and permanent disability. Attorney Chris Miller served as a government attorney in the Missouri Department of Labor and administered the Missouri Division of Workers' Compensation before entering private practice — he knows how insurers fight repetitive stress claims, and how to build the evidence to beat them.
(573) 499-0200 — call anytimeTrigger finger workers' compensation claims face frequent denials because the condition develops gradually rather than from a single workplace incident. Insurance carriers routinely argue that stenosing tenosynovitis results from aging, diabetes, rheumatoid arthritis, or other health conditions unrelated to work — rather than from your job duties.
Missouri imposes a strict legal standard: medical experts must establish that your job activities were more than 50% responsible for causing your trigger finger. This "prevailing factor" standard under Missouri workers' compensation statutes requires specific medical documentation — documentation that a skilled attorney knows how to gather and present. Disputes also arise over whether your employer's insurer has properly authorized and paid for medical treatment, which can derail your recovery and your claim.
Strict deadlines apply. Missouri law requires written notice to your employer within 30 days of discovering the injury, followed by a formal claim filed within two years. For gradual-onset occupational diseases, the date of injury is generally the last day of workplace exposure to the repetitive task. Missing either deadline can permanently extinguish your right to benefits.
When your trigger finger qualifies as a work-related occupational disease under Missouri law, you are entitled to a full range of benefits — including medical coverage, wage replacement, and compensation for permanent impairment to your hand and finger function.
All necessary and reasonable medical care including cortisone injections, splinting, trigger finger release surgery, physical therapy, and follow-up treatment. Your employer's insurer is responsible for all authorized treatment costs.
If your trigger finger prevents you from working during recovery, TTD benefits pay two-thirds of your average weekly wage — replacing lost income while you receive treatment and heal.
If trigger finger leaves lasting impairment to finger or hand function, you may receive permanent partial disability compensation based on the physician-assigned disability rating and Missouri's benefit schedule.
When trigger finger prevents returning to your prior job duties, you may qualify for vocational rehabilitation assistance — including job training and career retraining programs funded through the workers' compensation system.
Insurers frequently deny trigger finger claims by attributing the condition to diabetes, arthritis, or prior injuries. We challenge these denials and prove that your work activities were the prevailing factor in causing your condition.
Missouri law prohibits employers from firing, demoting, or otherwise retaliating against employees for filing a workers' compensation claim. We hold employers accountable when they cross that line. Learn about retaliation protections.
Trigger finger claims live or die on documentation. Missouri's prevailing factor standard demands specific, credible evidence linking your workplace activities to your diagnosis. The following factors significantly improve your claim's strength.
Trigger finger claims require careful documentation and tight deadline management. Chris Miller handles every step personally — no handoffs to associates or paralegals.
Trigger finger develops when the tendon sheath surrounding a flexor tendon becomes inflamed through repeated gripping, sustained finger flexion, or forceful hand movements. Any job requiring these motions across long shifts — day after day, year after year — can cause the condition. High-risk occupations in Missouri include:
If your job involved sustained gripping or repetitive hand motions and you have been diagnosed with trigger finger or stenosing tenosynovitis, your condition may qualify for workers' compensation benefits under Missouri law — even if your employer's insurer has already denied your claim.
Missouri employees must notify their employer in writing within 30 days of discovering a trigger finger injury. Failing to provide written notice within this period may permanently bar your claim for benefits. After providing notice, you have two years from the date of injury discovery to file a formal Claim for Compensation with the Missouri Division of Workers' Compensation.
For occupational diseases like trigger finger that develop gradually, the "date of injury" in Missouri is typically the last day you were exposed to the repetitive workplace activities that caused your condition. If your employer fails to file the required First Report of Injury, the filing period extends to three years. Missing either deadline can permanently extinguish your right to benefits — prompt action and legal guidance are essential.
Yes. Missouri workers' compensation law recognizes trigger finger — stenosing flexor tenosynovitis — as a compensable repetitive stress injury and occupational disease. The condition does not need to result from a single workplace accident to qualify for benefits. Gradual-onset repetitive stress injuries are covered when medical evidence establishes that your work activities were the prevailing factor in causing the condition.
The key is establishing that your job duties were more than 50% responsible for causing your trigger finger under Section 287.067 RSMo. This requires specific medical documentation connecting your repetitive work motions to your diagnosis — exactly the kind of evidence an experienced workers' compensation attorney knows how to develop.
A denial from your employer or their insurance carrier is not the end of your claim. Contested workers' compensation claims are resolved through the Missouri Division of Workers' Compensation, with appeals available before the Missouri Labor and Industrial Relations Commission. You have the right to legal representation throughout this process.
An experienced workers' compensation attorney can gather medical expert opinions establishing work-relatedness, compile workplace activity documentation, obtain statements from coworkers who witnessed your job duties, and present your full case before an administrative law judge. Insurance company denials are frequently overcome with the right evidence and legal advocacy.
Under Section 287.067 RSMo, a workers' compensation occupational disease claim requires proof that the work conditions were the "prevailing factor" — meaning more than 50% responsible — in causing your trigger finger. This is Missouri's legal threshold for connecting a gradual-onset condition to your employment.
Insurance companies frequently contest this standard by arguing that trigger finger is caused by diabetes, rheumatoid arthritis, age-related tendon changes, or off-work activities. Overcoming these defenses requires physician testimony specifically addressing the prevailing factor standard, detailed job duty documentation, and — in many cases — an independent medical examination with a physician who understands occupational injuries. Attorney Chris Miller's background administering the Missouri DWC gives him a clear understanding of what evidence satisfies this standard and how to present it effectively.
