Labor Day: When a Work-Related Orthopedic Injury Needs Care

Labor Day honors the people whose work supports our families, communities, and economy. It is observed on the first Monday in September as a celebration of American workers and their contributions.[1]

It is also a useful time to talk about something many workers quietly live with: pain, numbness, weakness, or loss of function caused or aggravated by the job.

Work-related orthopedic problems can begin with one clear event, such as a fall, twist, crush injury, or heavy lift. Others develop gradually from repeated force, awkward positions, vibration, prolonged gripping, overhead work, or too little recovery time. The right response depends on the injury, the worker, and the demands of the job.

This guide explains which symptoms need urgent care, when an orthopedic or physical therapy evaluation may help, how imaging and treatment decisions are made, and what Hawai‘i workers should know after an injury on the job.

What is a work-related musculoskeletal injury?

The musculoskeletal system includes bones, joints, muscles, tendons, ligaments, nerves, and spinal discs. A work-related musculoskeletal disorder is a problem caused or worsened by work demands or the work environment.

The National Institute for Occupational Safety and Health describes common workplace contributors such as lifting, pushing, pulling, carrying irregular loads, awkward posture, vibration, repetitive activity, and increasing the intensity, frequency, or duration of a task.[2]

Common examples include:

• Back or neck strain
• Rotator cuff irritation or tear
• Elbow tendinopathy
• Carpal tunnel syndrome
• Trigger finger
• Knee sprain or meniscus injury
• Ankle sprain or fracture
• Tendon injury
• Joint aggravation in a person with arthritis
• Fracture after a fall or crush injury

The words “work-related” do not identify the diagnosis. Shoulder pain after overhead work could come from the rotator cuff, biceps tendon, joint, or neck. Hand numbness could reflect carpal tunnel syndrome, another nerve problem, or a neck condition. A careful history and examination help separate these possibilities.

Sudden injury or gradual overload?

The timing provides an important clue.

A sudden injury

A specific event may cause an immediate pop, sharp pain, swelling, deformity, bruising, or inability to use the injured area. Examples include slipping on a wet floor, falling from a ladder, twisting a knee while carrying equipment, or feeling sudden shoulder pain while controlling a heavy load.

A gradual problem

Overuse symptoms often build more slowly. Pain may appear late in a shift, improve on days off, and return with the same task. Tingling may wake someone at night. Grip may weaken. A shoulder may become painful with repeated reaching, or the back may tighten after prolonged bending.

Gradual onset does not mean the problem is imaginary or unimportant. OSHA identifies forceful exertion, repetitive movement, awkward posture, contact stress, and vibration as recognized ergonomic risk factors for musculoskeletal disorders.[3]

Which symptoms require emergency care?

Some workplace injuries should bypass a routine office appointment.

Call 911 or seek emergency care for:

• A severe fall, crush injury, major collision, or high-energy accident
• An open fracture or bone visible through a wound
• A visibly deformed limb or joint
• Uncontrolled bleeding
• A hand or foot that is pale, blue, unusually cold, or losing circulation
• New paralysis or rapidly worsening weakness
• New loss of bowel or bladder control with back pain
• Severe neck or back pain after major trauma, especially with numbness or weakness
• Loss of consciousness, confusion, chest pain, or difficulty breathing

Prompt same-day assessment is also appropriate when a worker cannot bear weight after an injury, cannot actively move a joint, has rapidly increasing swelling, has persistent numbness or weakness, or develops a hot swollen joint with fever.

Do not drive yourself after a serious injury. Follow the workplace emergency plan and use emergency services when needed.

What should you do immediately after a less severe injury?

First, stop the task that caused the symptoms. Continuing to lift, climb, cut, push, or operate machinery with a painful or weak limb can worsen the injury and create a second safety risk.

For a mild injury without a red flag:

• Protect the area from another impact or load.
• Use relative rest rather than complete inactivity.
• Elevate a swollen hand, wrist, ankle, or knee when practical.
• Ice may provide short-term comfort during the first day or two. Protect the skin and use brief sessions.
• Maintain comfortable movement if the joint is stable and motion does not sharply increase pain.
• Avoid testing the injury repeatedly with heavy lifting or forceful stretching.
• Use over-the-counter medication only if it is safe with your medical conditions and other medicines.

Anti-inflammatory medicines are not appropriate for everyone, including some people with kidney disease, stomach ulcers, bleeding risk, cardiovascular disease, or certain medication interactions. Acetaminophen also has dose and liver-safety limits. When unsure, ask a clinician or pharmacist.

Report a workplace injury promptly in Hawai‘i

Medical care and the workers’ compensation process are related, but they are not the same thing.

The Hawai‘i Department of Labor and Industrial Relations advises an injured worker to report the injury to a supervisor or employer immediately, orally or in writing, and to explain the date, time, and circumstances. If the injury requires treatment beyond ordinary first aid or causes at least one day away from work, the employer generally must report it to the Disability Compensation Division within seven working days after learning about it.[4]

Practical steps include:

1. Tell your supervisor or employer as soon as reasonably possible.
2. Record when, where, and how the injury occurred.
3. Identify the body part and symptoms, including numbness, weakness, swelling, or loss of motion.
4. Note witnesses, equipment involved, and any immediate first aid.
5. Tell the treating clinician that the problem is work-related.
6. Keep copies of work notes, forms, medical records, restrictions, and communications.

The state says workers may obtain treatment from a physician of their choice who practices on the island where they live, although not every clinician accepts work-injury cases. Hawai‘i also limits a worker to one attending physician at a time and has notice requirements for changing physicians.[4]

If the employer does not file the WC-1 report, or if benefits are not being paid, the current WC-5 employee claim form and the Disability Compensation Division can help clarify the next administrative step.[5]

This is general information, not legal advice. Claim-specific questions should be directed to the Hawai‘i Disability Compensation Division, the insurer, or appropriate legal counsel.

When should an orthopedic evaluation happen?

An orthopedic evaluation is useful when symptoms suggest a structural injury or are not improving as expected.

Reasons to schedule an evaluation include:

• Pain that remains significant after several days of appropriate self-care
• Recurrent pain every time the worker resumes the task
• Swelling, bruising, catching, locking, or giving way
• Reduced motion or inability to lift the arm
• Numbness, tingling, or loss of grip strength
• Pain that interferes with sleep or ordinary daily activities
• A suspected fracture, tendon rupture, ligament injury, or joint instability
• Symptoms that require clear work restrictions
• A prior joint replacement or orthopedic condition affected by the injury

For suspected fractures or significant trauma, Pacific Bone & Joint’s fracture care service explains how urgent orthopedic assessment and follow-up are coordinated.

What happens during the evaluation?

The visit should connect the diagnosis to both the injury mechanism and the actual job.

A clinician may ask:

• What exactly were you doing when symptoms began?
• Was there a fall, twist, impact, sudden pull, or repeated task?
• Which movements reproduce the symptoms?
• Did pain begin immediately or build over time?
• Is there numbness, weakness, instability, locking, or loss of motion?
• What are the essential physical demands of the job?
• Is modified duty available?
• Were there symptoms or prior injuries before this event?

The examination may assess alignment, tenderness, swelling, motion, strength, stability, tendon function, sensation, circulation, gait, and the movements required for work.

Do you need an X-ray, MRI, or ultrasound?

Imaging should answer a clinical question, not simply document that pain exists.

X-rays

X-rays are usually the first test when a fracture, dislocation, arthritis, alignment problem, or hardware complication is possible. They do not show every tendon, ligament, nerve, or early stress injury.

MRI

MRI can provide more detail about tendons, ligaments, cartilage, muscle, bone marrow, and other soft tissues. It may help when the examination suggests a tear, an occult injury, or another diagnosis that would change treatment. Many common age-related findings also appear on MRI in people without pain, so the scan must be interpreted in context.

Ultrasound

Diagnostic ultrasound can evaluate selected tendons, muscles, fluid collections, and peripheral nerves while the body part moves. It can also guide certain injections or minimally invasive procedures. Ultrasound is useful for specific questions, but it does not replace X-ray or MRI for every condition.

What treatments help most work-related injuries?

Most work-related orthopedic problems do not begin with surgery. Treatment is matched to the diagnosis and may include several parts.

Temporary activity modification

Restrictions should be specific enough to protect healing tissue while preserving safe activity. Examples might address lifting, carrying, climbing, kneeling, repetitive gripping, overhead work, prolonged standing, or the use of vibrating tools.

“No work” and “full duty” are not the only options. Modified duty can sometimes allow a worker to stay engaged while an injury improves. The correct restrictions depend on the diagnosis, severity, medications, safety-sensitive responsibilities, and what the employer can accommodate.

Physical therapy

Physical therapy may address pain-limited movement, strength, endurance, balance, lifting mechanics, task tolerance, and graded return to work. The American Physical Therapy Association’s work-participation guidance supports individualized evaluation and management for people whose injury or illness limits their ability to work.[6]

Pacific Bone & Joint offers physical therapy in Honolulu and Waipahu for appropriate orthopedic and postoperative conditions.

Medication, bracing, or injection

Short-term medication, a brace, a splint, or an injection may help selected conditions. Each has limits. A brace should not substitute for diagnosis, and an injection should target a defined pain generator after risks and alternatives are considered.

Surgery

Surgery is considered when there is a problem that is unlikely to recover adequately with nonsurgical treatment or when delay could compromise the result. Examples may include an unstable fracture, complete tendon rupture, major ligament injury, progressive nerve deficit, severe carpal tunnel syndrome, or a repairable structural problem that continues to limit function.

The decision should account for the worker’s goals and job demands, not only the appearance of a scan.

What makes a return-to-work plan safe?

Return to work is a process, not a single date.

A useful plan identifies:

• Current functional limits
• Specific temporary restrictions
• The expected duration before reassessment
• Whether modified duty is available
• A progression in lifting, carrying, climbing, kneeling, gripping, or overhead work
• Whether medications impair driving or machinery operation
• Objective goals for motion, strength, endurance, balance, and task control

Pain does not have to be zero before every activity resumes, but worsening pain, swelling, weakness, instability, or neurologic symptoms should not be ignored. A worker may tolerate ordinary daily activity before being ready for repetitive heavy labor or a safety-sensitive task.

Prevention is more than “lift with your legs”

Good lifting technique helps, but there is no universal safe weight for every person, task, or shift.

NIOSH’s Revised Lifting Equation considers more than the number printed on a box. It evaluates factors such as the load’s position, travel distance, twisting, frequency, grip, and duration. Employers and safety professionals can use it to assess two-handed lifting tasks and redesign work when needed.[7]

Practical risk-reduction strategies include:

• Store heavier objects between knee and shoulder height when possible.
• Use carts, pallet jacks, hoists, or team lifts for heavy or bulky loads.
• Keep the load close and avoid twisting while carrying it.
• Push a suitable cart rather than pulling it when practical.
• Bring work in front of the body instead of repeatedly reaching behind or overhead.
• Use tools that fit the hand and allow a neutral wrist position.
• Reduce prolonged gripping, vibration, and static posture.
• Rotate demanding tasks and allow adequate recovery.
• Keep walkways clear, dry, well lit, and free of loose cords or unstable mats.
• Use the correct ladder and fall protection rather than improvising.
• Report early symptoms so the task can be reviewed before disability develops.

The most effective prevention often changes the task or environment. It should not depend entirely on a worker remembering perfect technique while tired, rushed, or handling an awkward load.

Common myths about workplace orthopedic injuries

”If I can still work, the injury cannot be serious”

Some tendon, ligament, nerve, and stress injuries still allow partial function. A worker may compensate until weakness or pain becomes more obvious.

”Every injury needs an MRI”

No. History, examination, and appropriate X-rays often establish the next step. MRI is most useful when it is likely to change management.

”Rest until the pain is completely gone”

Prolonged inactivity can reduce strength and work tolerance. Relative rest followed by graded activity is usually more useful for many uncomplicated conditions, once urgent injury has been excluded.

”Surgery is the fastest way back to work”

Not necessarily. Surgery is valuable for the right diagnosis, but it also requires healing and rehabilitation. Many strains, sprains, tendon problems, and overuse conditions recover without an operation.

”A workers’ compensation claim decides the medical diagnosis”

Claim administration and medical diagnosis are separate questions. The clinician’s job is to identify the condition, recommend appropriate care, document functional limits, and update restrictions based on recovery.

A Labor Day message for Hawai‘i workers

Hawai‘i’s workforce includes construction crews, warehouse and delivery teams, hotel and restaurant workers, health care professionals, mechanics, landscapers, farmers, fishers, office staff, teachers, first responders, and many others. Their physical demands differ, but the basic principles are shared:

Prevent hazards when possible, report injuries promptly, recognize warning signs, obtain the right diagnosis, and return to demanding work through a safe progression.

For a non-emergency bone, joint, tendon, muscle, or nerve problem related to work, request an orthopedic evaluation and tell the scheduling team that the injury occurred on the job. Bring the employer and insurance information available to you so the office can determine what is needed before the visit.
