How this affects your claim in practice
In a shoulder labral injury claim, the diagnosis is only the starting point. The records should connect MRI arthrogram or operative findings identifying the labral location and history of instability, catching or traumatic onset with the worker's practical limits, including overhead load, throwing, pulling, lifting away from the body and repetitive reach and whether duties expose the shoulder to recurrent instability. If the insurer disputes whether the labral finding is clinically significant, the response should address that reason directly.
Assessment source
- NSW Guidelines for the Evaluation of Permanent Impairment, paras 1.8-1.12: NSW Guidelines control the assessment method and AMA5 is used only where adopted and not modified.
- NSW Guidelines para 1.12: AMA5 Chapter 18 pain is excluded; chronic pain is assessed through the underlying diagnosed condition, while CRPS is assessed under the relevant NSW method.
- NSW Guidelines para 1.15: assessment should usually wait until maximum medical improvement, meaning the condition is stable and unlikely to change substantially in the next year.
- NSW Guidelines para 1.24: the effect on activities of daily living must not be used to increase or reduce an upper-extremity impairment calculated under the applicable upper-limb method.
- NSW Guidelines paras 1.26 and 2.8: values are rounded at each conversion stage; digit impairment converts to hand impairment, hand and other regional values convert to upper-extremity impairment, and AMA5 Table 16-3 converts upper-extremity impairment to WPI.
- NSW Guidelines paras 2.5 and 2.20: active movement is measured with a goniometer or inclinometer, passive movement is recorded for clinical comparison only, unreliable readings should be repeated, and the uninjured opposite limb may provide the worker's normal baseline.
- NSW Guidelines paras 2.8-2.13: values within one joint are added, same-limb regional values must be expressed in a common unit before combination, a deficit caused solely by a peripheral nerve lesion is not also rated as abnormal movement, and strength is used only in rare permitted cases.
- NSW Guidelines paras 2.14-2.21: NSW modifies the shoulder, biceps, impingement, joint-surface fracture, epicondylitis and CRPS methods in AMA5 Chapter 16.
- NSW Guidelines para 2.4: maximum upper extremity impairment is 60% WPI, equivalent to amputation through the shoulder.
What injuries or conditions may be assessed?
Labral injury can include an anterior Bankart lesion after dislocation, a superior labrum anterior-to-posterior (SLAP) tear, a posterior labral tear or associated biceps-anchor pathology.
- MRI findings alone do not determine WPI. The relevant permanent finding may be restricted active movement, supported instability, surgery or a separately assessable biceps condition.
- Shoulder symptoms should also be separated from cervical radiculopathy and a named peripheral nerve lesion.
Symptoms and findings that matter
For shoulder labral injury, flexion means lifting the arm forward and overhead; extension means reaching backwards; abduction means lifting sideways; and adduction means bringing the arm towards the body.
When shoulder labral injury affects rotation, external rotation can limit reaching behind the head or washing hair, while internal rotation can limit reaching behind the back or dressing. These examples explain function, not an extra percentage.
The NSW examination for shoulder labral injury measures internal and external rotation with the arm abducted to 90 degrees and the elbow flexed to 90 degrees, or at the worker's maximum symmetrical abduction if 90 degrees is not possible.
Only repeatable active shoulder movement is converted for shoulder labral injury. Passive movement, imaging, pain and daily activities provide clinical context but cannot replace the prescribed calculation.
What investigations are usually relevant
Investigations for shoulder labral injury may include repeat active flexion, extension, abduction, adduction, internal rotation and external rotation measurements and ultrasound or MRI identifying cuff, labral, biceps or joint pathology and whether it matches the examination. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- Operation reports for repair, stabilisation, tenodesis, clavicle resection or arthroplasty and follow-up imaging where relevant.
- Physiotherapy records showing whether movement has stabilised and whether the measurements are consistent over time.
How WPI is assessed for this body part
For shoulder labral injury, the assessor first identifies whether repeatable active shoulder movement or a specific diagnosis-based NSW rule best describes the accepted impairment. Surgery or an MRI label does not select a percentage by itself.
Flexion, extension, abduction, adduction, internal rotation and external rotation values for shoulder labral injury are added within the shoulder before the upper-extremity result is converted through AMA5 Table 16-3.
If shoulder labral injury includes a named nerve lesion, movement caused solely by that lesion is not rated again. Sensory and motor nerve findings instead follow the applicable named-nerve method.
Strength is only a rare alternative in a pain-free shoulder labral injury assessment where reduced movement does not adequately reflect the deficit; it is not added to duplicate pain or movement loss.
Reaching, dressing and washing-hair examples help describe shoulder labral injury, but NSW paragraph 1.24 prevents an activities-of-daily-living adjustment to the calculated upper-extremity result.

Worked assessment illustrations
These examples paraphrase the assessment reasoning in the source material. They explain method only and are not predicted outcomes.
Illustration 1
Shoulder labral injury: reduced shoulder movement in several planes
Assumed facts: Assume a labral injury or repair leaves stable active restriction and the imaging finding has been matched to the clinical shoulder examination. At maximum medical improvement, repeat active measurements record 156 degrees flexion, 20 degrees extension, 140 degrees abduction, 40 degrees adduction, 50 degrees external rotation and 40 degrees internal rotation.
Method: For this shoulder labral injury illustration, Using the corresponding AMA5 shoulder-motion figures, the assumed losses contribute 1%, 2%, 2%, 0%, 1% and 3% upper-extremity impairment. Values for the same shoulder joint are added: 1 + 2 + 2 + 0 + 1 + 3 = 9% upper-extremity impairment.
Illustrative outcome: This shows how the relevant shoulder labral injury findings move through the upper-limb conversion process. AMA5 Table 16-3 converts 9% upper-extremity impairment to 5% WPI. NSW paragraph 1.24 does not permit an extra uplift or reduction for activities of daily living. This paraphrased illustration is not an estimate for any individual claim.

What usually does not increase WPI
Pain, tenderness, weakness complaints or an imaging label without a stable measurable impairment.
Passive movement loss used as though it were active movement impairment.
Grip or other strength loss used to duplicate pain, restricted movement, deformity or nerve loss.
An activities-of-daily-living adjustment added to or subtracted from the calculated upper-extremity value.
The same functional loss counted once under a nerve method and again as restricted movement.
Evidence checklist
The records for shoulder labral injury should include the accepted injury description and any dispute notice identifying the body part and diagnosis and repeat active range-of-motion measurements and opposite-side comparison where appropriate. They are most useful when the diagnosis, examination and practical restrictions are consistent.
- Imaging, operative reports and treatment records for the actual tendon, joint, fracture or arthroplasty condition.
- Sensory mapping, motor testing, static two-point discrimination or electrodiagnostic evidence where a nerve lesion is alleged.
- Work-duties and therapy records explaining the practical movement or nerve function affected.
How this injury commonly happens at work
Work-related shoulder labral injury can arise through traction on the arm and a fall onto the hand or shoulder. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related shoulder labral injury can arise through a dislocation causing a Bankart lesion and forceful overhead work affecting the superior labrum and biceps anchor. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For shoulder labral injury, an insurer may dispute whether the labral finding is clinically significant and whether symptoms arise from the labrum, cuff, biceps or neck. The written decision should be answered with evidence directed to those reasons.
Further disputes about shoulder labral injury may concern whether instability is objectively supported and whether surgery and ongoing restrictions relate to the accepted injury. The decision notice should identify which issue is relied on and the evidence said to support it.
Treatment and surgery issues
Depending on the diagnosis and treating opinion, management of shoulder labral injury may involve physiotherapy, injection or arthroscopic repair where supported and post-repair rehabilitation addressing movement and stability. The request should explain the expected functional benefit and its connection to the accepted injury.
Weekly payments and work capacity
Capacity evidence for shoulder labral injury should address overhead load, throwing, pulling, lifting away from the body and repetitive reach and whether duties expose the shoulder to recurrent instability. Proposed duties must be sustainable for the proposed hours, not merely possible once.
How NSW Work Injury Claim can help
For shoulder labral injury, a claim review can help to separate diagnosis, work exposure and capacity evidence and test suitable duties against actual hand, wrist, elbow or shoulder demands. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
For shoulder labral injury, a claim review can help to review treatment denial reasons and IME assumptions and plan WPI or dispute steps where appropriate. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
Common questions about shoulder labral injury claims
How can work cause or aggravate shoulder labral injury?
For shoulder labral injury, the relevant work history may include traction on the arm, a fall onto the hand or shoulder, and a dislocation causing a Bankart lesion. A claim still depends on the actual chronology and medical evidence. The records should identify what changed, when symptoms began or worsened, and how the diagnosed condition affects the worker's duties.
How is WPI assessed for shoulder labral injury?
For shoulder labral injury, the assessor first identifies whether repeatable active shoulder movement or a specific diagnosis-based NSW rule best describes the accepted impairment. Surgery or an MRI label does not select a percentage by itself. For shoulder labral injury, flexion means lifting the arm forward and overhead; extension means reaching backwards; abduction means lifting sideways; and adduction means bringing the arm towards the body. The assessor must apply the NSW Guidelines to the accepted, stable condition; the diagnosis or an operation does not by itself determine a percentage.
Which records are most useful for a shoulder labral injury assessment?
A shoulder labral injury assessment commonly needs the accepted injury description and any dispute notice identifying the body part and diagnosis, repeat active range-of-motion measurements and opposite-side comparison where appropriate, imaging, operative reports and treatment records for the actual tendon, joint, fracture or arthroplasty condition, and sensory mapping, motor testing, static two-point discrimination or electrodiagnostic evidence where a nerve lesion is alleged. Those records are most useful when they describe the same diagnosis, examination findings, treatment history and practical work restrictions.
What does an insurer commonly dispute about shoulder labral injury?
For shoulder labral injury, common issues include whether the labral finding is clinically significant, whether symptoms arise from the labrum, cuff, biceps or neck, and whether instability is objectively supported. The response should address the insurer's stated reason with the relevant chronology, clinical findings, investigations and duties evidence rather than relying on the diagnosis alone.
How can shoulder labral injury affect weekly payments and suitable duties?
Capacity evidence for shoulder labral injury may need to address overhead load, throwing, pulling, lifting away from the body and repetitive reach and whether duties expose the shoulder to recurrent instability. A certificate should describe what the worker can do safely and sustainably. Proposed duties should then be checked against those restrictions and the real demands of the job.
What does not establish WPI for shoulder labral injury by itself?
For shoulder labral injury, pain, tenderness, weakness complaints or an imaging label without a stable measurable impairment. WPI depends on the accepted injury, objective findings and the method required by the NSW Guidelines after the condition has stabilised.
