Shoulder injuries at work — the injury, the recovery, and the claim.

Shoulders do the reaching, lifting, and overhead work — and they fail in ways insurers love to blame on age. Here's what's actually happening in an injured shoulder, how treatment unfolds, and why "degeneration" on your MRI doesn't end your claim.

Why shoulders are a workers' comp battleground

The shoulder trades stability for range of motion — the most mobile joint in the body is also among the easiest to injure. Overhead trades (electricians, painters, drywallers), warehouse and delivery work, healthcare lifting, and assembly lines generate constant shoulder claims, through single accidents and through years of repetitive reaching.

What makes shoulder claims contentious is the same thing that makes back claims contentious: imaging findings that appear with age. Rotator cuff fraying and partial tears are common in uninjured adults over 40, so insurers routinely argue the damage predates the job. In most states that argument misses the legal point — work that caused or aggravated the tear is compensable, and a shoulder that worked fine before the incident and doesn't after it is powerful evidence.

Get prompt care if…

You can't raise your arm at all after an incident, the shoulder looks visibly deformed or dislocated, there's sudden severe weakness, or numbness spreading down the arm. Complete cuff tears and dislocations do better with early treatment — waiting weeks costs both recovery and credibility.

The common work-related shoulder injuries

InjuryWhat's happeningTypical course
Rotator cuff tearThe tendons that lift and rotate the arm tear — partially or completely — from one heavy lift or years of overhead work.Partial tears often improve with therapy; full-thickness tears frequently need surgical repair with months of recovery.
Impingement / tendinitisTendons pinched and inflamed under the shoulder blade's arch — the classic repetitive-reaching injury.Weeks to months with therapy and activity change; a common precursor to tears when work doesn't change.
Labral tear (incl. SLAP)The cartilage rim stabilizing the socket tears — falls, jerking loads, repetitive throwing-type motion.Therapy first; surgery for mechanical symptoms. Often coexists with other findings.
Dislocation / separationThe joint comes apart (dislocation) or the collarbone joint sprains (separation) — falls and direct blows.Reduction and rehab; repeat dislocations and higher-grade separations may need surgery.
Frozen shoulderThe capsule stiffens after injury or immobilization — motion painfully shrinks.Slow: months of therapy. A real, compensable consequence of an injury even though it develops afterward.

How treatment usually unfolds

  1. 1

    Conservative care first

    Activity modification, anti-inflammatories, and physical therapy — the evidence-backed first line for most shoulder problems, and the stage insurers require before approving more.

  2. 2

    Imaging when it doesn't settle

    X-rays early; MRI when significant pain or weakness persists. Remember the aggravation rule when the report mentions "degenerative changes" — nearly every adult shoulder has some.

  3. 3

    Injections

    Corticosteroid injections calm impingement and buy therapy time — commonly disputed in utilization review, commonly approved on appeal.

  4. 4

    Surgery when structure demands it

    Arthroscopic cuff repair, labral repair, or decompression. Recovery is famously long — sling time, then months of therapy, often 6–12 months to full duty for heavy work. Plan your claim (and wage benefits) around that reality.

What shoulder injuries mean for your claim

  • Report the mechanism precisely. "Felt a pop lifting a 70-pound box overhead" ages far better than "shoulder pain." Mechanism is what beats the age-degeneration argument.
  • Repetitive shoulders are cumulative trauma claims. No single incident needed — years of overhead work count, with their own deadline clocks that usually start when a doctor connects the condition to work.
  • Document weakness, not just pain. Can't lift the milk jug, can't reach the top shelf, can't sleep on that side — functional specifics drive both treatment approval and ratings.
  • Honor overhead restrictions everywhere. Nothing sinks a shoulder claim like being seen doing the exact overhead work the doctor prohibited.

What drives shoulder settlement value

  • Full-thickness tears and completed surgery — the largest value inflections.
  • Documented loss of motion and strength at MMI — shoulders are rated heavily on measured range of motion, which makes honest effort at the rating exam critical.
  • Permanent overhead/lifting restrictions that keep you from your trade.
  • Future medical — revision-surgery risk, and progression toward shoulder replacement in severe cases.
  • State specifics — in New York, a permanently limited shoulder is an arm schedule loss of use award, payable even after returning to full-pay work.

Frequently asked questions

No. Degenerative findings are the norm in working-age shoulders, including pain-free ones. The legal question is whether work caused or aggravated your condition — and a shoulder that functioned fully before a specific incident or work exposure is strong evidence that it did. This exact dispute is what medical-legal exams resolve.
This is one of the highest-stakes timing decisions in comp. Settling before surgery — especially with a full-and-final settlement — means the surgery's cost, its recovery time, and any complications become yours. Understand how future medical is valued, and don't sign anything pre-surgery without a professional review.
Possibly — that's cumulative trauma, and it's covered. The clock generally starts when you knew (or a doctor told you) the condition was work-related, so don't sit on it once the connection is made. Occupational history — years of overhead work, load weights, line speeds — becomes your key evidence.
