How this affects your claim in practice
In a forearm injury claim, the diagnosis is only the starting point. The records should connect ultrasound, MRI, X-ray or nerve conduction studies where relevant and treating GP, physiotherapy and specialist reports with the worker's practical limits, including grip strength, keyboarding, tool use, overhead work and lifting tolerance and dominant-hand limits and two-handed tasks. If the insurer disputes whether symptoms are work-related or age-related, 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 2.14-2.20 modify the shoulder, biceps, impingement, joint-surface fracture and epicondylitis methods in AMA5 Chapter 16; para 2.21 directs upper-limb CRPS to the NSW Chapter 17 method rather than an AMA5 Chapter 16 or Chapter 18 pain rating.
- 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?
Forearm injury can include radius or ulna fracture, interosseous membrane damage, distal radioulnar joint injury, tendon or muscle injury, compartment syndrome consequences, or median, ulnar or radial nerve damage.
- Pronation and supination loss may be central after a forearm fracture even when wrist flexion and extension are relatively preserved.
Symptoms and findings that matter
Pronation turns the palm down and supination turns it up. These active rotations are measured in the elbow/forearm region, while wrist flexion, extension and deviation are calculated at the wrist.
Imaging should address union, malalignment and joint involvement; the neurological examination should identify any named-nerve sensory or motor deficit.
What investigations are usually relevant
Investigations for forearm injury may include contemporaneous GP, specialist, physiotherapy or hand-therapy records identifying the exact diagnosis and progression to maximum medical improvement and ultrasound, MRI, X-ray, CT, operation reports or arthroplasty records where they explain tendon, labral, joint, fracture or surgical findings. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- Nerve conduction studies or EMG where clinically relevant, interpreted with the sensory and motor examination rather than used alone.
- Repeat active movement measurements and a clear note of whether pain, guarding or inconsistency affected the examination.
- Duties evidence describing overhead reaching, lifting, pushing, pulling, gripping, keyboard work, tool use and forearm rotation where relevant.
How WPI is assessed for this body part
Valid pronation and supination impairment values are added within the elbow/forearm region. A separate wrist or named-nerve result is combined only after conversion to the same upper-extremity unit.
The same movement loss is not counted again if it arises solely from the nerve lesion, and the final upper-extremity result converts through AMA5 Table 16-3.

Worked assessment illustrations
These examples paraphrase the assessment reasoning in the source material. They explain method only and are not predicted outcomes.
Illustration 1
Forearm fracture with loss of rotation
Assumed facts: Assume a united forearm fracture leaves repeatable active pronation and supination loss but normal wrist movement and no supported peripheral nerve deficit.
Method: The applicable forearm-rotation values are added within the elbow region before conversion from upper-extremity impairment to WPI.
Illustrative outcome: No extra wrist or nerve value is added on those assumed facts. Exact angles must be measured; this is not a predicted percentage.

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 forearm 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 forearm injury can arise through repetitive reaching, gripping, keyboard or tool use and lifting above shoulder height or away from the body. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related forearm injury can arise through falls onto an outstretched arm, forceful pulling, pushing or carrying, and vibration, awkward wrist posture or sustained hand use. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For forearm injury, an insurer may dispute whether symptoms are work-related or age-related and whether repetitive work materially contributed to the diagnosis. The written decision should be answered with evidence directed to those reasons.
Further disputes about forearm injury may concern whether surgery, injections, splints or therapy are reasonably necessary, whether suitable duties still exceed gripping, reaching or lifting limits, and whether restrictions have been underestimated by an IME. 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 forearm injury may involve physiotherapy, hand therapy, splinting, injections or specialist review and surgery such as decompression, repair or fixation where clinically indicated. The request should explain the expected functional benefit and its connection to the accepted injury.
Further management of forearm injury may involve workstation or task modification to reduce repeat aggravation and rehabilitation after immobilisation or surgery. The request should explain why the proposed step is connected to the accepted injury and what functional improvement is expected.
Weekly payments and work capacity
Capacity evidence for forearm injury should address grip strength, keyboarding, tool use, overhead work and lifting tolerance and dominant-hand limits and two-handed tasks. Proposed duties must be sustainable for the proposed hours, not merely possible once.
For forearm injury, capacity evidence should address safe duties that avoid repetition or forceful use and weekly payments where partial capacity is disputed. The question is whether those activities can be performed safely, reliably and for the proposed hours—not whether a task can be attempted once.
How NSW Work Injury Claim can help
For forearm 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 forearm 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 forearm injury claims
How can work cause or aggravate forearm injury?
For forearm injury, the relevant work history may include repetitive reaching, gripping, keyboard or tool use, lifting above shoulder height or away from the body, and falls onto an outstretched arm. 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 forearm injury?
For forearm injury, valid pronation and supination impairment values are added within the elbow/forearm region. A separate wrist or named-nerve result is combined only after conversion to the same upper-extremity unit. Pronation turns the palm down and supination turns it up. These active rotations are measured in the elbow/forearm region, while wrist flexion, extension and deviation are calculated at the wrist. 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 forearm injury assessment?
A forearm 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 forearm injury?
For forearm injury, common issues include whether symptoms are work-related or age-related, whether repetitive work materially contributed to the diagnosis, and whether surgery, injections, splints or therapy are reasonably necessary. 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 forearm injury affect weekly payments and suitable duties?
Capacity evidence for forearm injury may need to address grip strength, keyboarding, tool use, overhead work and lifting tolerance, dominant-hand limits and two-handed tasks, and safe duties that avoid repetition or forceful use. 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 forearm injury by itself?
For forearm 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.
