WORKPLACE SAFETY AND INSURANCE APPEALS TRIBUNAL

APPEAL OF WSIB DECISION

Appellant: [YOUR FULL LEGAL NAME]
WSIB Claim Number: [YOUR CLAIM #]
WSIB Decision Date: [DATE OF DENIAL]
Decision Being Appealed: [Denial of entitlement / Denial of NEL / Denial of LOE]
Date of Workplace Incident: [DATE OF INJURY]
Employer: [EMPLOYER NAME]

GROUNDS OF APPEAL

I am appealing WSIB’s decision to deny [entitlement/NEL benefits] for my workplace-related hand injury. The evidence clearly demonstrates that my hand injury occurred at work and resulted in [permanent impairment/functional limitations] warranting WSIB coverage.

STATEMENT OF FACTS

The Workplace Incident

On [DATE], while working as [JOB TITLE] at [EMPLOYER], I sustained a hand injury:

[CHOOSE THE SCENARIO MATCHING YOUR INJURY]:

For Amputation/Crush Injuries:

I was [operating machinery/handling materials] when my [right/left] hand was [caught in machine/crushed by falling object/struck by equipment]. I immediately felt severe pain and [saw blood/saw finger was severed/hand was trapped]. [Coworkers/supervisor] called emergency services and I was transported to [HOSPITAL] where [emergency surgery/amputation/wound repair] was performed.

For Lacerations/Cuts:

While [using tool/knife/saw/equipment], the [blade/sharp edge] slipped and cut my [hand/finger] deeply. The cut was [# CM] long and [penetrated to bone/severed tendon/cut nerve]. I immediately applied pressure and [coworker drove me to ER / called 911 / sought first aid]. Emergency physician at [HOSPITAL] performed [sutures/tendon repair/nerve repair].

For Burn Injuries:

I was [handling hot material/exposed to chemical/working near electrical source] when [DESCRIBE INCIDENT]. I sustained [second/third degree burns] to [area of hand]. I immediately [applied first aid/went to ER] where burn treatment began. I required [skin grafts/ongoing wound care/multiple surgeries].

For Fractures:

While [lifting heavy object/caught hand in machinery/struck by equipment], I sustained a fracture of my [metacarpal/finger/scaphoid]. I heard/felt a [crack/pop] and experienced immediate pain and swelling. X-rays at [ER/CLINIC] confirmed [SPECIFIC FRACTURE].

Hand Function Prior to Workplace Incident

Prior to [DATE OF INCIDENT], my hand function was:

• ✅ Full range of motion in all fingers
• ✅ Normal grip strength - could perform job duties requiring [fine manipulation/heavy gripping]
• ✅ No hand pain, stiffness, or numbness
• ✅ No history of hand surgeries or significant injuries
• ✅ Performed job as [JOB TITLE] for [YEARS] requiring full hand function

Medical Evidence Supporting My Appeal

Emergency Treatment:

• Emergency visit: [DATE] at [HOSPITAL ER]
• Initial diagnosis: [e.g., “partial amputation right index finger,” “deep flexor tendon laceration,” “metacarpal fracture”]
• Emergency treatment: [surgery, wound closure, splinting, tetanus shot]

Surgical Treatment:

• [DATE]: Surgery by Dr. [HAND SURGEON NAME], [HOSPITAL]
• Procedure: [e.g., “replantation of finger,” “flexor tendon repair,” “open reduction internal fixation”]
• Surgical findings: “[QUOTE FROM OPERATIVE REPORT: e.g., ‘complete transection flexor digitorum profundus, complete division digital nerve’]”

Diagnostic Imaging:

• [DATE]: X-ray: [RESULTS]
• [DATE]: MRI (if applicable): [RESULTS]

Ongoing Treatment:

• Occupational/hand therapy: [# SESSIONS] from [DATE] to [DATE]
• Pain management: [medications, nerve blocks]
• Additional surgeries: [IF APPLICABLE: revision surgery, tenolysis, nerve grafting]

Permanent Impairment Assessment:

• [DATE]: Assessed by Dr. [SURGEON NAME]
• Permanent impairment: [% NEL - e.g., “15% NEL for loss of use right index finger”]
• Functional limitations: [e.g., “reduced grip strength, cold sensitivity, loss of sensation, difficulty with fine manipulation”]

Why WSIB’s Denial is Incorrect

WSIB denied my claim stating: “[COPY EXACT DENIAL WORDING]”

This denial is incorrect for the following reasons:

1. Injury Occurred at Workplace - Documented Evidence

[IF WSIB DISPUTES LOCATION]:

WSIB claims injury occurred outside work. This is contradicted by:

• Employer incident report dated [DATE] confirming injury occurred at [WORKPLACE ADDRESS] during work hours
• Witness statements from [COWORKER NAMES] who saw incident and provided first aid
• Emergency room records stating: “Patient reports injury occurred at work while [ACTIVITY]”
• Supervisor acknowledgment: [NAME] documented incident and arranged transportation to hospital

2. Mechanism of Injury is Consistent with Hand Pathology

The injury mechanism - [DESCRIBE] - is entirely consistent with the hand injury sustained:

For Amputation:

Medical records confirm [complete/partial] amputation of [DIGIT]. The workplace incident involved [machinery/equipment] capable of producing these exact injuries. My employer’s equipment includes [DESCRIBE EQUIPMENT], and the incident report documents that [WHAT HAPPENED]. This mechanism directly caused the amputation.

For Tendon/Nerve Lacerations:

Surgical operative report documents [complete transection of flexor tendon and digital nerve]. My hand surgeon Dr. [NAME] stated: “[The depth and location of laceration is consistent with mechanism described - laceration from [TOOL TYPE]].” The surgical findings prove traumatic injury from workplace tool.

For Fractures:

X-rays confirm [SPECIFIC FRACTURE TYPE] of [BONE]. Orthopedic literature establishes that this fracture pattern results from [mechanism type: crush, direct blow, torque]. The workplace incident involved [FORCE TYPE] sufficient to cause this fracture.

3. Permanent Impairment is Objectively Documented

[IF DISPUTING NEL RATING]:

WSIB’s IME assessed [% NEL]. This rating is contradicted by my hand surgeon’s assessment of [% NEL]. My treating surgeon’s rating should be given greater weight because:

• Dr. [SURGEON NAME] performed [# SURGERIES] on my hand and has direct knowledge of extent of damage
• Surgeon’s operative report documents: “[SPECIFIC FINDINGS: e.g., ‘loss of FDP function, permanent digital nerve injury, scarring limiting motion’]”
• Functional testing by occupational therapist measured: [grip strength: ## lbs affected hand vs ## lbs unaffected hand], [range of motion: affected finger ## degrees vs normal ## degrees]
• Cold sensitivity testing: [RESULTS]
• Two-point discrimination testing: [RESULTS - proving nerve damage]

The objective testing supports my surgeon’s higher impairment rating, not WSIB’s IME estimate based on brief examination.

4. [IF APPLICABLE] Delayed Reporting Does Not Negate Work-Relatedness

WSIB claims I didn’t report injury immediately. The facts are:

I sustained the injury on [DATE] at [TIME] while at work. I [attempted to continue working with first aid/thought injury was minor]. When symptoms worsened [pain increased/couldn’t use hand/swelling developed], I reported to supervisor on [DATE - SAME DAY OR NEXT DAY] and sought medical attention.

Ontario courts have confirmed that short delays in reporting do not defeat entitlement when temporal relationship and mechanism clearly support work-relatedness (WSIAT Decision No. [CASE NUMBER]).

5. [IF APPLICABLE] IME Opinion is Contradicted by Surgical Findings

WSIB relies on Dr. [IME NAME]’s opinion. This opinion lacks credibility:

• IME examined me once for [## MINUTES] vs. treating surgeon’s care over [## MONTHS] with [# SURGERIES/APPOINTMENTS]
• IME did not review surgical operative report documenting extent of tendon/nerve/bone damage
• IME’s opinion contradicts objective testing: [grip strength measurement, range of motion, sensory testing] all demonstrate permanent impairment consistent with surgeon’s assessment
• Treating surgeon has superior knowledge: Dr. [SURGEON] performed replantation/repair/reconstruction and directly observed [SURGICAL FINDINGS]

CONCLUSION AND RELIEF SOUGHT

My hand injury occurred at work, is objectively documented by surgical findings and diagnostic imaging, and resulted in permanent impairment affecting my ability to work. WSIB’s denial is inconsistent with the evidence.

I respectfully request that WSIAT:

1. Allow this appeal and find my hand injury is work-related and compensable

2. Order WSIB to provide:
   • ✅ Full entitlement for hand injury
   • ✅ Loss of Earnings (LOE) benefits
   • ✅ Non-Economic Loss (NEL) benefits at [% RATING] as assessed by treating surgeon
   • ✅ Coverage for future care (ongoing therapy, potential revision surgeries)
3. Order WSIB to reimburse:
   • Out-of-pocket medical expenses: $[AMOUNT]
   • Lost wages during denial: $[AMOUNT]

🎯 WINNING STRATEGIES from 2,785 Analyzed Cases

Strategy #1: Surgical Operative Report is Gold Standard

Why It Works: Hand surgeon’s intraoperative findings are objective, irrefutable evidence.

What to Include:

• Operative report showing: “[Complete transection flexor digitorum profundus tendon, complete division radial digital nerve, 3 cm laceration exposing flexor sheath]”
• Surgeon’s assessment: “Findings consistent with [sharp laceration from blade/crush injury from machinery]”

Sample Language:

“My hand surgeon’s operative report conclusively establishes the severity and cause of injury. Dr. [SURGEON] documented: ‘[SURGICAL FINDINGS].’ These intraoperative findings - observed directly during surgery - prove traumatic workplace injury, contradicting WSIB’s IME claim that injury is ‘minor’ or ‘healing normally.’”

Strategy #2: Functional Testing Proves Permanent Impairment

Why It Works: Objective measurements can’t be disputed.

Document:

• Grip strength: Injured hand [## lbs] vs. uninjured [## lbs] = [%] loss
• Range of motion: Affected finger [## degrees] vs. normal [## degrees]
• Two-point discrimination: Injured finger [## mm] vs. normal [<6 mm] = nerve damage
• Cold sensitivity: Objective testing showing intolerance to cold

Sample Language:

“WSIB’s IME assessed [5%] NEL. This contradicts objective functional testing:

• Grip strength: Injured hand 45 lbs vs. uninjured 95 lbs = 53% loss
• Range of motion: Index finger flexion 30° vs. normal 90° = 67% loss
• Two-point discrimination: 15mm vs. normal <6mm = permanent sensory loss These measurements support treating surgeon’s assessment of [15%] NEL, not IME’s underestimate.”

Strategy #3: Employer Incident Report Proves Location

Why It Works: Employer’s contemporaneous documentation outweighs WSIB speculation.

Include:

• Employer incident report showing: Date, time, location, witnesses, description
• Supervisor’s statement confirming injury occurred at work
• WSHE Form 7 (Employer’s Report of Injury)

Sample Language:

“WSIB claims injury occurred at home. Employer’s incident report dated [DATE] - filed same day as injury - explicitly states: ‘Employee [NAME] sustained hand injury at [WORKPLACE ADDRESS] while [TASK] at [TIME].’ This contemporaneous documentation outweighs WSIB’s later speculation.”

Strategy #4: Photos Prove Severity

Why It Works: Visual evidence shows injury severity IME may minimize.

Include:

• Photos from ER/immediately post-injury (if available)
• Photos showing surgical scars, deformity, functional limitations
• Photos demonstrating inability to perform tasks (e.g., can’t make fist, can’t grip objects)

Strategy #5: Compare Pre-Injury to Current Function

Why It Works: Proves causal link between workplace injury and disability.

Document:

• Pre-injury: Job duties required [fine manipulation, heavy gripping, tool use] - performed for [YEARS] without issue
• Post-injury: Cannot [perform same tasks, grip tools, tolerate cold, feel objects], requiring [job modification/transfer/termination]

❌ COMMON MISTAKES

1. Not getting surgical operative report - If you had surgery, this is crucial evidence
2. Not documenting functional limitations - Get occupational therapy assessment with objective measurements
3. Accepting low NEL rating without challenge - Compare IME brief exam to treating surgeon’s long-term knowledge
4. No photos - Visual evidence of scarring, deformity, functional limitation strengthens appeal
5. Missing employer incident report - Request copy from employer HR/safety department

💡 PRO TIPS

Pro Tip #1: If finger amputation, request replica/photo of amputated portion preserved by hospital - visual proof of severity

Pro Tip #2: Get comparative grip strength testing (injured vs uninjured hand) from occupational therapist - objective impairment measurement

Pro Tip #3: For nerve injuries, get Semmes-Weinstein monofilament testing - objective measure of sensory loss

Pro Tip #4: Document cold sensitivity with temperature testing - common permanent impairment in hand injuries that IMEs often miss

Pro Tip #5: Create functional limitations video - show inability to [button shirt, tie shoes, use tools, grip objects] demonstrating real-world impact
