How this affects your claim in practice
In a wrist injury claim, the diagnosis is only the starting point. The records should connect x-ray, CT or MRI for fracture, ligament, TFCC or arthritis findings and active flexion, extension, radial deviation and ulnar deviation measurements with the worker's practical limits, including keyboard and mouse use, gripping, lifting, pushing, pulling and tool control. If the insurer disputes whether pain arises from the wrist joint, tendon, nerve or forearm, 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?
Wrist injury can involve distal radius or carpal fracture, scapholunate or lunotriquetral ligament injury, triangular fibrocartilage complex injury, tendon injury, post-traumatic arthritis, stiffness, instability or median/ulnar nerve involvement.
- The assessment should distinguish wrist-joint movement from forearm pronation and supination, which are rated at the elbow.
Symptoms and findings that matter
For wrist injury, wrist flexion bends the palm towards the forearm and extension bends the hand back.
Radial deviation in a wrist injury examination moves the hand towards the thumb; ulnar deviation moves it towards the little finger.
Repeat active wrist injury measurements are converted under the wrist figures and added within that joint. Passive movement is recorded for comparison, not substituted into the calculation.
What investigations are usually relevant
Investigations for wrist 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
Wrist flexion, extension, radial deviation and ulnar deviation are measured actively for wrist injury; their impairment values are added within the wrist before conversion to WPI.
Pronation and supination are forearm movements rated at the elbow. A wrist injury assessment should not place those values in the wrist total or count the same restriction twice.
A qualifying displaced joint-surface fracture or named median, ulnar or radial nerve lesion may require a diagnosis-based or nerve method instead of treating all wrist injury findings as movement loss.
Strength is rarely added for wrist injury, particularly where pain, restricted wrist motion, deformity or nerve dysfunction already explains the functional loss.
Work examples such as gripping, keyboard use or tool handling explain wrist injury in practice but do not change the calculated result under NSW paragraph 1.24.

Worked assessment illustrations
These examples paraphrase the assessment reasoning in the source material. They explain method only and are not predicted outcomes.
Illustration 1
Wrist injury: wrist movement loss in four planes
Assumed facts: Assume a stable wrist injury leaves repeatable restriction after fracture alignment, ligament stability, tendon pathology and nerve symptoms have been reviewed. Repeat active measurements record 30 degrees flexion, 60 degrees extension, 10 degrees radial deviation and 20 degrees ulnar deviation.
Method: For this wrist injury illustration, On the assumed AMA5 wrist-motion figures, these measurements contribute 5%, 0%, 2% and 2% upper-extremity impairment. Values within the wrist are added to 9% upper-extremity impairment.
Illustrative outcome: This shows how the relevant wrist injury findings move through the upper-limb conversion process. AMA5 Table 16-3 converts 9% upper-extremity impairment to 5% WPI. Forearm pronation and supination are rated at the elbow, not added as wrist movement. 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 wrist 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 wrist injury can arise through a fall onto the hand and forceful twisting or impact. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related wrist injury can arise through repetitive wrist loading aggravating a diagnosed tendon or ligament condition. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For wrist injury, an insurer may dispute whether pain arises from the wrist joint, tendon, nerve or forearm and whether a joint-surface fracture meets the NSW displacement rule. The written decision should be answered with evidence directed to those reasons.
Further disputes about wrist injury may concern whether movement measurements are reproducible and whether pronation and supination were incorrectly treated as wrist motion. 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 wrist injury may involve immobilisation, hand therapy, injection, fixation or ligament/tendon surgery where supported. The request should explain the expected functional benefit and its connection to the accepted injury.
Weekly payments and work capacity
Capacity evidence for wrist injury should address keyboard and mouse use, gripping, lifting, pushing, pulling and tool control. Proposed duties must be sustainable for the proposed hours, not merely possible once.
How NSW Work Injury Claim can help
For wrist 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 wrist 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 wrist injury claims
How can work cause or aggravate wrist injury?
For wrist injury, the relevant work history may include a fall onto the hand, forceful twisting or impact, and repetitive wrist loading aggravating a diagnosed tendon or ligament condition. 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 wrist injury?
For wrist injury, wrist flexion, extension, radial deviation and ulnar deviation are measured actively for wrist injury; their impairment values are added within the wrist before conversion to WPI. For wrist injury, wrist flexion bends the palm towards the forearm and extension bends the hand back. 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 wrist injury assessment?
A wrist 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 wrist injury?
For wrist injury, common issues include whether pain arises from the wrist joint, tendon, nerve or forearm, whether a joint-surface fracture meets the NSW displacement rule, and whether movement measurements are reproducible. 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 wrist injury affect weekly payments and suitable duties?
Capacity evidence for wrist injury may need to address keyboard and mouse use, gripping, lifting, pushing, pulling and tool control. 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.
Does wrist injury automatically receive a fixed WPI percentage?
No. For wrist injury, one verified example is displaced fracture involving a joint surface: 2% upper extremity impairment or 1% WPI where criteria are met, under NSW Guidelines para 2.17. That value applies only when its stated criteria are met. Pain, tenderness, weakness complaints or an imaging label without a stable measurable impairment.
