Spring brings warmer weather, increased outdoor activity and a predictable rise in musculoskeletal injury claims. For legal and insurance professionals managing these files, one of the most practically important decisions is selecting the right medical specialty for an Independent Medical Examination (IME).
In musculoskeletal claims, the most common options are orthopaedic surgery and physiatry (physical medicine and rehabilitation). Each brings meaningful but distinct clinical expertise. Choosing between them - or knowing when to combine both - can significantly affect the quality, scope, and defensibility of the resulting report.
Orthopaedic surgeons are trained to diagnose and treat conditions of the musculoskeletal system - bones, joints, ligaments, tendons, and cartilage. Their surgical expertise gives them a uniquely authoritative perspective on structural pathology: whether a fracture has healed appropriately, whether a joint replacement was indicated, whether a rotator cuff tear requires operative intervention, or whether surgical outcomes meet the standard of care.
An orthopaedic IME is most appropriate when:
The injury involves a specific structural diagnosis: fractures, joint dislocations, ligamentous tears, articular cartilage damage, or post-operative complications are areas where orthopaedic expertise is directly relevant.
The clinical question involves surgical necessity or appropriateness: If the referral partner needs to know whether surgery was indicated, whether the procedure was appropriate, or whether the outcome is consistent with the intervention performed, orthopaedic expertise is often the most appropriate specialty opinion.
Causation turns on mechanism of injury and anatomical correlation: Orthopaedic surgeons are well positioned to opine on whether a specific mechanism of injury is consistent with the type and severity of structural findings on imaging.
Claims involve joint pathology in specific regions: Hip, knee, shoulder, and spine injuries with clear anatomical correlates are typically well served by orthopaedic assessment.
Physiatrists, specialists in physical medicine and rehabilitation. take a fundamentally different approach. While orthopaedics focuses primarily on structural pathology, physiatry is oriented toward functional capacity: how an injury or condition affects what a person can do, and what is needed to optimize recovery and return to meaningful activity.
A physiatry IME is most appropriate when:
The primary question is functional rather than structural: When the referral partner needs to understand a claimant's capacity for work, activities of daily living, or specific occupational demands, physiatry provides a more comprehensive functional lens than orthopaedic opinion.
Chronic pain with musculoskeletal components: Physiatrists are trained to evaluate and manage chronic musculoskeletal pain conditions that do not have a clear surgical solution - including myofascial pain, chronic regional pain, post-whiplash syndrome, and complex chronic back pain.
Interdisciplinary treatment planning: When the file requires an opinion on appropriate rehabilitation, a realistic recovery trajectory, or whether maximum medical improvement has been reached, physiatry is particularly well suited.
Multi-system involvement: Injuries affecting multiple body regions- particularly in polytrauma or complex motor vehicle accident claims - benefit from physiatry's integrative approach.
Return-to-work evaluations: Physiatrists are highly experienced in functional capacity and work tolerance analysis required for return-to-work decisions.
In high-value or complex musculoskeletal claims, there is a strong argument for requesting both an orthopaedic and a physiatry IME - addressing structural and functional questions in a coordinated fashion.
An orthopaedic surgeon establishes the anatomical diagnosis, comments on the appropriateness of treatment, and offers a structural prognosis. A physiatrist then assesses the functional implications of that structural picture - what the claimant can and cannot do, and what the realistic rehabilitation pathway looks like.
This complementary approach is particularly valuable in catastrophic motor vehicle accident claims, chronic pain claims where the absence of ongoing structural pathology makes functional assessment the more relevant metric, and cases involving return-to-work disputes.
A simple decision framework for musculoskeletal IME specialty selection:
Request orthopaedic when there is a specific structural diagnosis, surgical appropriateness or outcome is in question, or the mechanism of injury and anatomical correlation needs expert opinion.
Request physiatry when the primary question is functional capacity, the claim involves chronic pain or chronic musculoskeletal conditions, return-to-work is central, or a multi-system functional picture is needed.
Request both when the claim is high-value or catastrophic, structural and functional questions are both material, or maximum defensibility requires complementary expert opinions.
Medylex's national network includes experienced orthopaedic surgeons and physiatrists across Canada. If you are navigating a complex musculoskeletal claim and are uncertain which specialist best fits the clinical question, our team is available to support the referral process.
Musculoskeletal claims are among the most common in personal injury and disability practice - but common does not mean simple. Selecting the right specialty for an IME is a consequential decision that affects the scope, quality, and defensibility of the resulting opinion.
Understanding the distinct strengths of orthopaedic surgery, physiatry, and related specialties helps referral partners make better decisions for their clients - and obtain clearer and more defensible opinions from the assessment process.
