Metacarpal Fracture

Explanation of Diagnosis

A metacarpal fracture is a break in one of the five long bones in your hand between your wrist and fingers. It commonly happens from falls, punches, sports impacts, or twisting injuries. Symptoms often include pain over the affected bone, swelling, bruising, and difficulty gripping or moving the involved finger. Sometimes the hand may look crooked or feel unstable, and sensation can be affected if swelling presses on a nerve.

Specific Work Modifications

• Avoid tasks that require gripping, pinching, or lifting with the injured hand whenever possible.
• Use tools with larger grips or padded handles to reduce force on the metacarpal.
• Switch to one-handed or assisted computer/mouse use (for example, using the non-injured hand for typing and scrolling).
• Keep the hand elevated when you can during breaks to reduce swelling.
• Set up your workstation so you do not have to reach, twist, or support body weight with the injured hand.
• Do not wear rings on the affected hand until swelling is fully resolved, and remove any jewelry if advised.

Specific Activity Modifications

• Avoid punching, hitting drills, or contact sports until your clinician clears you.
• Pause weightlifting exercises that stress gripping (such as deadlifts, rows, pull-ups, farmer carries) with the injured hand.
• Choose lower-impact workouts (such as walking, stationary cycling, or leg-focused machines) while keeping the hand protected.
• If you do martial arts, rock climbing, or racquet sports, switch to technique-only practice without force and only with medical clearance.
• Avoid pushing up from chairs/bed with the injured hand; use the non-injured hand or another support.
• Keep hobbies like woodworking, lifting boxes, and using hand tools to a minimum until pain and swelling settle.

Recommended Supplements

• Vitamin C 500 mg once or twice daily may support connective tissue health during bone healing.
• Calcium 1,000 to 1,200 mg per day total (from food plus supplements if needed) helps support bone mineral needs.
• Vitamin D3 1,000 to 2,000 IU daily may help if your vitamin D level is low or sun exposure is limited.
• Omega-3 fish oil 1,000 mg daily may help reduce inflammatory symptoms for some people during recovery.

Recommended Nutrition and Hydration

Diet Recommendations

• Aim for adequate protein from meals (such as eggs, dairy, fish, beans, lean meats, or tofu) to support tissue repair.
• Include calcium-rich foods daily (milk, yogurt, cheese, fortified alternatives) and vitamin D sources when possible.
• Eat fruits and vegetables regularly, especially those high in vitamin C (citrus, berries, peppers) to support healing.
• Limit alcohol and avoid nicotine products, as they can interfere with bone healing and recovery quality.

Hydration Tips

• Drink water regularly through the day; include fluids with meals and after activity.
• If you swell easily, avoid very large swings in fluid intake and monitor how your hand responds to salty foods.

Home Exercise Prescription

Perform these exercises gently 1 to 3 times per day, unless your clinician has specifically restricted motion.

1. Tendon glides: With your hand supported, slowly move from straight fingers to a relaxed hook position, then to a gentle full fist as tolerated, then back to straight; do 5 to 10 repetitions.
2. Finger range-of-motion (protected): If you are allowed to move the injured finger, straighten and bend it within comfort, avoiding sharp pain; do 5 to 10 repetitions.
3. Thumb motion: Touch thumb to each fingertip lightly (or to the base of the small finger if that is all you can do); do 5 to 10 touches.
4. Wrist or forearm mobility (only if allowed): Rotate your forearm palm up to palm down gently, or do small wrist flexion/extension within your comfort range; do 5 to 10 repetitions.
5. Shoulder and elbow movement: Move your shoulder through comfortable circles and bend/straighten the elbow to prevent stiffness; do 10 to 15 repetitions.

Stop any exercise that causes sharp pain, a sudden increase in swelling, new numbness or tingling, or worsening deformity.
