Diagnosis Explanation:

Jersey finger is a tear or rupture of the flexor digitorum profundus (FDP) tendon, which allows the fingertip to bend. It commonly occurs when the finger is forcefully extended while gripping, such as when grabbing an opponent’s jersey in sports.

Symptoms:

• Inability to bend the fingertip (DIP joint).
• Pain, swelling, and bruising on the palm side of the finger.
• Tenderness along the flexor tendon.
• Possible lump (if the tendon retracts into the palm).

Specific Work Modifications:

• If your job involves typing or writing: Use voice dictation software and take frequent breaks.
• If your job requires manual labor: Avoid gripping tools or lifting heavy objects with the affected hand.
• If your job is desk-based: Use an ergonomic keyboard and wrist support, and keep the hand elevated when possible.
• Avoid: Forceful gripping, repetitive finger use, and tasks that put strain on the affected finger.

Specific Activity Modifications:

• If you play sports: Avoid gripping-heavy sports (football, rugby, rock climbing, weightlifting) until cleared for return.
• If you play an instrument or do crafting: Use adaptive tools with larger grips to reduce strain.
• If you do gardening or cooking: Use ergonomic tools and avoid forceful pinching motions.
• Avoid: Activities that require strong grip strength, pulling motions, or excessive finger flexion.

Recommended Supplements:

• Collagen Peptides – 10g daily for tendon repair.
• Vitamin C – 500mg daily to support collagen synthesis.
• Glucosamine & Chondroitin – 1500mg/1200mg daily for joint and tendon health.
• Omega-3 Fatty Acids – 1000mg daily to reduce inflammation.
• Turmeric (Curcumin) – 500-1000mg daily for pain relief.

Recommended Nutrition and Hydration:

• Increase Lean Protein (chicken, fish, tofu, eggs) to support tendon healing.
• Eat Anti-Inflammatory Foods (berries, leafy greens, turmeric, nuts) to reduce swelling.
• Consume Hydrating Foods (cucumber, watermelon, citrus) to maintain tendon lubrication.
• Limit Processed Foods & Sugars to prevent inflammation.
• Hydration: Drink 8-10 cups of water daily to support tendon recovery.

Home Exercise Prescription (Rehabilitation for Jersey Finger)

Early Phase (0-2 Weeks, Protecting the Tendon & Reducing Pain):

• Splinting – Wear a DIP extension splint full-time to prevent further damage.
• RICE Protocol – Rest, Ice (15-20 min, 3x/day), Compression, Elevation.
• Passive Finger Flexion – Use the opposite hand to gently bend the fingertip, 10 reps, 2x/day.

Strengthening Phase (2-6 Weeks, Restoring Mobility & Function):

• Towel Scrunches – Place a towel on a flat surface, use fingers to scrunch it, 10 reps, 2x/day.
• Finger Lifts – Place hand flat, lift each finger individually, 10 reps per finger, 2x/day.
• Rubber Band Finger Extensions – Wrap a rubber band around fingers, open hand against resistance, 10 reps, 2x/day.

Advanced Phase (6+ Weeks, Preventing Recurrence & Maintaining Function):

• Grip Strengthening (Soft Ball Squeeze) – Squeeze a soft ball 5 seconds, repeat 10 reps, 2x/day.
• Finger-to-Thumb Opposition – Touch thumb to each fingertip, 10 reps, 2x/day.
• Wrist Strengthening (Light Resistance Band) – Strengthen wrist and forearm muscles to prevent re-injury, 10 reps, 2x/day.
