The 3 Most Common Types of Workplace Injuries in Missouri (and What Workers' Comp Covers)

Every year, thousands of workers across central Missouri are hurt on the job. Some injuries happen in a single moment — a fall from a ladder, a forklift collision, a piece of machinery catching a hand. Others build up over weeks and months of repetitive strain, until one bad lift leaves someone unable to work. Regardless of how it happens, a workplace injury can upend your income, your health, and your family's stability all at once.

Missouri law requires employers with 5 or more employees — and construction companies with even one employee — to carry workers' compensation insurance. That coverage provides medical treatment, wage replacement, and disability benefits when a work-related injury occurs in the course and scope of employment.

The Missouri Division of Workers' Compensation recognizes several categories of eligible claims: traumatic physical injuries, repetitive motion injuries, occupational diseases, occupational illnesses, and mental health conditions related to workplace stress. Understanding which category your injury falls into — and how Missouri law covers it — matters for how your claim proceeds.

Before diving in, one important legal concept: Missouri's § 287.020 RSMo requires that a work injury be the prevailing factor in causing your medical condition — not just a contributing factor. This matters because employers and insurers frequently argue that a pre-existing condition, not the job, is really to blame. That argument is especially common with back injuries and joint problems. Having the right medical evidence and legal support is how you push back.

1. Overexertion Injuries

Overexertion is the single most common cause of workplace injuries in Missouri and across the country. These repetitive motion injuries and musculoskeletal disorders happen when a worker strains or tears muscle, tendon, or soft tissue by pushing their body beyond what it can handle — lifting a heavy load, pulling a stuck object, carrying materials across a worksite, or performing the same motion hundreds of times a day. Missouri law explicitly covers musculoskeletal disorders that develop gradually over time due to repeated physical motions or strain.

Common overexertion injuries include:

• Herniated or bulging discs in the lower back
• Rotator cuff tears in the shoulder
• Muscle strains and sprains in the back, neck, or arms
• Tendinitis and repetitive stress injuries in the wrists, elbows, and knees

These injuries show up in virtually every industry — warehousing, construction, nursing, manufacturing, delivery driving, agriculture. The problem with overexertion claims is that insurance companies often argue the injury is "degenerative" — the result of aging or a pre-existing condition — rather than something caused by the job. This is where the prevailing factor standard comes into play. Your medical records, job duties, and how the injury developed all matter in making that case.

What Workers' Comp Covers for Overexertion Injuries

If your overexertion injury is accepted as work-related, Missouri workers' compensation covers all reasonable and necessary medical treatment, including doctor visits, physical therapy, imaging, and surgery. If the injury keeps you out of work, you're also entitled to temporary total disability (TTD) benefits — typically two-thirds of your average weekly wage while you recover. If the injury leaves you with a permanent impairment, you may also be entitled to permanent partial disability (PPD) benefits based on the extent of that impairment.

2. Falls, Slips, and Trips

Falls are the second leading cause of serious workplace injuries in Missouri. OSHA consistently ranks falls as one of the top causes of workplace fatalities in construction — but slips, trips, and falls happen in every industry, from retail and restaurant work to healthcare and manufacturing.

Common causes include:

• Wet or slippery floors without adequate warning signs
• Uneven surfaces, loose flooring, or unmarked steps
• Falls from ladders, scaffolding, or elevated platforms
• Inadequate guardrails or fall protection on elevated work areas
• Cluttered walkways and poor housekeeping

The injuries from a serious fall can be devastating — broken bones, traumatic brain injury (TBI), spinal cord damage, and in some cases, fatalities. A fall from even a moderate height on a construction site can permanently alter a person's ability to work.

What Workers' Comp Covers for Fall Injuries

Missouri workers' compensation covers the full cost of medical treatment for fall injuries, including emergency room care, surgery, rehabilitation, and ongoing specialist visits. TTD benefits apply while you're unable to work. For serious falls involving permanent disability — a back fusion, a TBI, a spinal injury — PPD or permanent total disability (PTD) benefits may be available. In fatal fall cases, surviving dependents may be entitled to death benefits under Missouri law.

One important note: if your fall was caused by a third party — a subcontractor's negligence, defective equipment, or an unsafe property you were sent to — you may have a personal injury claim in addition to your workers' comp benefits. The two are not mutually exclusive.

3. Struck-By and Caught-In Injuries

The third major category covers injuries caused by contact with objects or machinery — being struck by something moving toward you, or getting caught in or between equipment. These injuries are especially prevalent on construction sites, in manufacturing plants, and in warehouse and distribution environments.

Common examples include:

• Being struck by a moving forklift or vehicle on a worksite
• Falling tools, materials, or equipment dropping from above
• Getting a hand, arm, or clothing caught in unguarded machinery
• Being pinned between equipment and a fixed surface
• Struck-by injuries in delivery or transportation work

The severity of these injuries is often extreme. Crush injuries, traumatic amputations, head trauma, and internal organ damage are not uncommon. Recovery can be long, incomplete, or impossible — and the financial impact on a family can be severe.

What Workers' Comp Covers for Struck-By/Caught-In Injuries

Workers' compensation covers all medical treatment, TTD during recovery, and PPD or PTD benefits for lasting impairment. In the most serious cases, the Missouri Division of Workers' Compensation also administers a Second Injury Fund, which can provide additional benefits when a new workplace injury combines with a prior disability to produce a greater overall disability than either would alone.

As with fall injuries, struck-by and caught-in cases sometimes involve third-party liability — defective equipment, a negligent contractor, or a driver who caused a vehicle accident. Those claims run separately from workers' comp and can result in additional compensation.

Missouri's Prevailing Factor Standard — What It Means for Your Claim

Missouri's workers' compensation law sets a specific bar for proving a work injury. Under § 287.020 RSMo, the work accident or activity must be the prevailing factor in causing both the resulting medical condition and any disability. It isn't enough to show that work contributed to the injury — the work has to be the primary, dominant cause.

This standard matters most in cases involving the back, joints, and repetitive use injuries, where employers and insurers almost always argue that age, prior injuries, or underlying degeneration — not the job — is the real culprit. The right medical documentation, combined with a clear account of how the injury happened and what your job required, is how you establish that work was the prevailing factor.

The 30-Day Reporting Rule

Missouri law requires you to report a workplace injury to your employer within 30 days of the accident — or within 30 days of when you knew or should have known that your condition was related to your work. Missing this deadline can result in a denial of your claim.

For repetitive injuries that develop gradually, the clock typically starts running when you first connect your symptoms to your job. If you're unsure whether you've missed the window, contact an attorney before assuming the worst. There are limited exceptions, and the facts of your situation matter.

What to Do After a Workplace Injury in Missouri

If you've been hurt at work — whether it's an overexertion injury that built up over time or an acute injury from a fall or equipment accident — the steps you take in the first days matter significantly:

1. Report the injury to your employer in writing as soon as possible. Don't assume a verbal report is enough. Get it documented.
2. Seek medical care promptly. In Missouri, your employer generally controls the choice of treating physician in a workers' comp case. You typically need to treat with a doctor they authorize — unless it's an emergency.
3. Document everything. Keep records of how the injury happened, witnesses who saw it, your symptoms, and every medical visit. Take photos if relevant.
4. Be careful what you sign. Don't sign a settlement or release without understanding what you're giving up.
5. Consult an attorney early. Workers' comp claims can be denied, disputed, or undervalued. An attorney who knows the Missouri workers' comp system can protect your rights from the start.
