I now have excellent data from MGH, textbooks, and clinical sources. Let me compile a comprehensive, well-organized response.
Clavicle Fracture (Broken Collarbone) - Complete Rehabilitation Guide
Anatomy & Why Rehab Matters
The clavicle (collarbone) connects the sternum to the acromion of the scapula and acts as a strut that transmits forces between the arm and trunk. After a fracture, surrounding muscles (pectoralis major, deltoid, trapezius, rotator cuff) lose coordinated function. Without structured rehabilitation, the shoulder joint becomes stiff ("frozen shoulder"), muscles atrophy, and scapular mechanics break down - making return to full function much harder.
Rehabilitation Phases - Step by Step
PHASE 1: Weeks 0-6 (Protection & Early Motion)
Goals: Allow bone healing, prevent joint stiffness, minimize muscle loss.
Sling use: Wear sling full-time (day and night). Remove only to bathe.
Exercise 1 - Pendulum Swings
Purpose: Maintain shoulder joint mobility using gravity without loading the fracture.
How to do it:
- Stand next to a table or chair
- Bend forward at the waist (about 90°), support yourself with the uninjured arm on the surface
- Let the injured arm hang straight down, completely relaxed
- Using gentle body rotation (NOT shoulder muscle effort), swing the arm:
- Forward and backward (10 circles)
- Side to side (10 circles)
- Clockwise and counterclockwise small circles (10 each)
- Keep the motion small and pain-free
Reps/Sets: 2-3 times per day | Duration: 5-10 minutes
Exercise 2 - Grip Strengthening
Purpose: Maintain hand and forearm circulation; prevent distal stiffness while shoulder is immobilized.
How to do it:
- Hold a soft stress ball, therapy putty, or rolled towel
- Squeeze firmly for 5 seconds
- Slowly release over 3 seconds
- Repeat 10-15 times per session
Reps/Sets: 3 sets of 10-15 reps | Frequency: 3-4x/day
Exercise 3 - Wrist and Elbow Circles
Purpose: Keep joints below the shoulder mobile; prevent stiffness from sling immobilization.
How to do it:
- With arm resting in sling, gently flex and extend the wrist (up/down)
- Rotate wrist in circles (10 each direction)
- Gently bend and straighten the elbow within comfort range
- Perform these slowly and smoothly
Reps/Sets: 10-15 reps each movement | Frequency: 3x/day
Exercise 4 - Shoulder Shrugs
Purpose: Activate the trapezius and maintain scapular elevation without moving the fracture site.
How to do it:
- Sit or stand upright with arm in sling
- Shrug both shoulders straight up toward your ears
- Hold for 3-5 seconds at the top
- Slowly lower back down
- Keep movement controlled - no rapid jerking
Reps/Sets: 10-15 reps | Sets: 2-3 | Frequency: 2x/day
Exercise 5 - Scapular Pinches (Retraction)
Purpose: Activate middle trapezius and rhomboids; maintain posture and scapular control.
How to do it:
- Sit or stand upright
- Gently squeeze both shoulder blades backward and together
- Imagine holding a pencil between your shoulder blades
- Hold for 5 seconds
- Slowly release
Reps/Sets: 10 reps x 3 sets | Frequency: 2-3x/day
PHASE 2: Weeks 6-12 (Active Range of Motion + Isometrics)
Prerequisites: X-ray confirmation of callus formation (early bone healing visible on imaging). Pain should be significantly reduced.
Sling: Discontinue sling at 6-8 weeks (or per physician instruction).
Exercise 6 - Assisted Arm Elevation (Wand/Cane Exercise)
Purpose: Use the uninjured arm to guide the injured arm into elevation, reducing load on the fracture.
How to do it:
- Hold a cane, umbrella, or broomstick with both hands, shoulder-width apart
- Lie on your back (supine position) or stand
- Use your good arm to slowly push the injured arm upward (forward flexion) to the point of mild resistance
- Hold for 5-10 seconds, then slowly lower
- Gradually increase the height over days/weeks
Reps/Sets: 10 reps x 3 sets | Frequency: 2x/day
Exercise 7 - Wall Crawl (Finger Walking)
Purpose: Progressively regain shoulder flexion by using the wall as support.
How to do it:
- Stand facing a wall, arm's length away
- Place your fingertips on the wall at waist height
- Slowly "walk" fingers up the wall as far as pain allows
- Mark your highest point with a small piece of tape - try to beat it each session
- Hold at maximum height for 5-10 seconds, then walk fingers back down
Reps/Sets: 10 reps | Frequency: 2-3x/day
Exercise 8 - Isometric Internal Rotation
Purpose: Strengthen internal rotators (subscapularis) without joint movement.
How to do it:
- Stand in a doorframe or at the corner of a wall
- Bend elbow to 90°, keep elbow tucked against your side
- Place the palm of the hand against the wall/doorframe
- Gently push palm INTO the wall (as if trying to rotate arm inward) without actually moving
- Hold 5 seconds, relax
Reps/Sets: 10 reps x 3 sets | Frequency: 2x/day
Exercise 9 - Isometric External Rotation
Purpose: Strengthen external rotators (infraspinatus, teres minor) without movement.
How to do it:
- Stand with the back of your hand/forearm against a wall
- Elbow bent to 90°, tucked at your side
- Push the BACK of your hand into the wall (as if trying to rotate arm outward) without moving
- Hold 5 seconds, relax
Reps/Sets: 10 reps x 3 sets | Frequency: 2x/day
Exercise 10 - Supported Shoulder Rotation (Forearm Slide)
Purpose: Restore internal and external rotation with support.
How to do it:
- Sit at a table with your elbow resting on the surface, bent to 90°
- Keeping elbow fixed, slide the forearm forward (internal rotation) and backward (external rotation)
- Move within a comfortable, pain-free range
- Do not force at end range
Reps/Sets: 10 reps each direction x 3 sets | Frequency: 2x/day
PHASE 3: Weeks 13-18 (Strengthening Phase)
Prerequisites: Full or near-full range of motion, fracture healing confirmed on X-ray, minimal pain.
Exercise 11 - Theraband Internal Rotation
Purpose: Progressive resistance strengthening of internal rotators.
How to do it:
- Attach a resistance band to a fixed point at elbow height
- Stand sideways with injured arm closest to the anchor
- Elbow bent 90°, arm at your side; hold band in hand
- Slowly rotate forearm across your body (inward rotation)
- Hold 1-2 seconds, return slowly to start
Reps/Sets: 3 sets of 15 reps | Resistance: Start with light/yellow band
Exercise 12 - Theraband External Rotation
Purpose: Strengthen external rotators and rear deltoid.
How to do it:
- Anchor band at elbow height; stand with injured side AWAY from anchor
- Elbow bent 90°, tucked at side
- Rotate forearm outward (away from body)
- Hold 1-2 seconds, return slowly
Reps/Sets: 3 sets of 15 reps | Frequency: Once daily
Exercise 13 - Prone Row
Purpose: Strengthen middle trapezius, rhomboids, and posterior rotator cuff.
How to do it:
- Lie face down on a bed or bench, arm hanging off the edge
- Holding a light weight (0.5-1 kg to start), bend elbow and pull arm upward
- Squeeze shoulder blade back and down at the top
- Slowly lower back down
Reps/Sets: 3 sets of 10-12 reps
Exercise 14 - Prone Extension
Purpose: Strengthen posterior deltoid and scapular stabilizers.
How to do it:
- Lie face down, arm hanging off the edge of bed
- With a light weight, raise arm straight back behind you (extension)
- Squeeze at the top for 2 seconds, slowly lower
Reps/Sets: 3 sets of 10-12 reps
Exercise 15 - Standing Scaption (Scapular Plane Elevation)
Purpose: Safe, functional shoulder elevation that loads the clavicle gradually.
How to do it:
- Stand upright, arm at your side with thumb pointing up
- Raise arm diagonally forward (about 30° forward from the side - the "scapular plane")
- Elevate to 90° (shoulder height) then slowly lower
- Do NOT shrug the shoulder when raising
Reps/Sets: 3 sets of 10-15 reps | Start without weight, add 0.5-1 kg when comfortable
Exercise 16 - Forward Punch (Serratus Activation)
Purpose: Activate serratus anterior - critical for scapular winging prevention.
How to do it:
- Lie on your back with arm pointing toward ceiling (90° flexion)
- Reach your hand further toward the ceiling by pushing the shoulder blade forward
- Do not bend the elbow; movement is purely from the shoulder blade
- Hold 2 seconds, relax
Reps/Sets: 3 sets of 10-15 reps
PHASE 4: Weeks 19-28+ (Return to Full Activity)
Prerequisites: Full range of motion achieved, excellent scapular control, no pain, radiographic union confirmed.
- Closed Kinetic Chain (CKC) exercises: Ball against wall (weight-bearing through arm), wall push-ups progressing to standard push-ups
- Plyometric exercises (for athletes): Rebounder throws, wall dribbles overhead, deceleration drills with weighted ball
- Overhead pressing with gradual weight increase
- Return to sport interval programs (swimming, throwing, tennis, golf) - begin at 19-20 weeks, per physiotherapist guidance
- Weight training: Resume gradually between 28-32 weeks
Precautions - What to Avoid
During Phase 1 (0-6 weeks) - STRICT
| Precaution | Reason |
|---|
| No lifting objects heavier than a cup of water | Fracture not yet stable |
| No pushing or pulling with the injured arm | Risk of displacement |
| No overhead reaching | Excessive force at fracture site |
| No driving | Cannot react safely; sling impairs control |
| No sleeping on injured side | Direct pressure on fracture |
| Do NOT remove sling without medical advice | Sling maintains alignment |
| Avoid contact sports entirely | Re-fracture risk |
During Phase 2 (6-12 weeks) - MODERATE
- Avoid lifting more than 1-2 kg
- Avoid forceful pushing, pulling, or pressing overhead
- Avoid reaching behind your back or placing hand behind your head
- Stop any exercise that produces sharp pain (mild discomfort is acceptable)
- Do NOT progress to weights until callus confirmed on X-ray
During Phase 3 (13-18 weeks)
- No push-ups or pushing movements until Phase 4
- No lifting heavy weights overhead or across the body
- Avoid ballistic/jerky movements
- Always warm up before strengthening exercises
Warning Signs - STOP Exercise and Seek Review
Consult your doctor or physiotherapist immediately if you experience:
- Sharp, sudden increase in pain at the fracture site
- Visible deformity or new "bump" at the collarbone
- Numbness, tingling, or weakness in the hand/fingers
- Shortness of breath (may indicate pneumothorax - a rare complication)
- Skin becoming red, warm, or swollen over the fracture
- Fever (possible infection, especially after surgery)
Patient Education - Key Messages
Understanding Your Injury
- The clavicle is one of the most commonly fractured bones - you are not alone. Over 90% of uncomplicated fractures heal successfully without surgery.
- Healing has three stages: Inflammatory (0-2 weeks), Reparative/callus formation (2-8 weeks), Remodeling (months). Exercises must match the healing stage.
- X-ray evidence of healing (callus) is the GREEN LIGHT to progress exercises - do not self-advance based on pain alone.
Sling Care
- Wear your sling 24 hours a day, including during sleep, for the first 3-6 weeks unless told otherwise.
- You may remove it only to bathe - support your arm with the other hand during bathing.
- When putting on shirts, dress the injured arm first; when undressing, remove the uninjured arm first.
- Sleep positions: Elevate head of bed slightly; sleeping semi-reclined (30-45°) is often most comfortable.
Pain Management
- Ice application: 15-20 minutes to the fracture area, 3-4 times daily for the first 1-2 weeks - place a cloth between ice and skin to prevent frostbite.
- Take pain medications (e.g., paracetamol, ibuprofen) as prescribed - do not exceed recommended doses.
- Do not mix pain medications without physician guidance.
- Mild aching after exercise is normal. Sharp pain = stop.
Posture & Daily Life
- Avoid slumping forward - poor posture strains the healing bone. Consciously sit tall.
- When standing or walking, keep shoulder blades gently drawn back (not squeezed tightly).
- Avoid carrying bags on the injured shoulder for at least 3 months.
- Use the uninjured arm for all lifting and carrying tasks during Phase 1.
- When typing or using a phone, support the elbow to avoid fatigue.
Nutrition for Bone Healing
- Calcium: Aim for 1000-1200 mg/day (dairy, leafy greens, fortified foods). Adequate calcium accelerates callus formation.
- Vitamin D: 800-1000 IU/day recommended - essential for calcium absorption. Get 15-20 minutes of sunlight or use a supplement.
- Protein: Adequate protein intake (0.8-1.2 g/kg/day) supports tissue repair.
- Avoid smoking - nicotine severely impairs bone healing and increases non-union risk by up to 40%.
- Limit alcohol - disrupts calcium metabolism and bone repair.
Driving
- Do NOT drive while wearing a sling or while range of motion is restricted.
- Most patients can return to driving at 6-8 weeks (after sling removal), but check with your doctor first - depends on which side is injured and whether the car is manual or automatic.
Return to Work
- Desk/office workers: Generally return within 1-3 weeks, using the uninjured arm.
- Manual workers or those lifting >5 kg: Wait for fracture union (typically 8-12 weeks) and medical clearance.
- Heavy labor / overhead work: May require 3-4 months before return.
Follow-Up Schedule (Typical)
- Week 1-2: Wound check (if surgical)
- Week 3-4: Clinical review and X-ray
- Week 6: X-ray to assess callus
- Week 12: Assessment for return to activity
- Week 20-28: Return to sport evaluation
Psychological Recovery
- Feeling frustrated about activity restrictions is normal and expected.
- Communicate with your physiotherapist if pain is interfering with sleep or daily function - this can be addressed with positioning aids or medication adjustment.
- Stay active within restrictions (walking, stationary cycling with one hand) to maintain cardiovascular fitness and mood.
Summary Timeline at a Glance
| Timeframe | Stage | Focus |
|---|
| 0-2 weeks | Immobilization | Pain control, sling, distal joint mobility |
| 2-6 weeks | Early protected motion | Pendulum, shrugs, grip, scapular control |
| 6-12 weeks | Active ROM + isometrics | Wand exercises, wall crawl, isometric rotations |
| 13-18 weeks | Strengthening | Theraband, prone exercises, scaption |
| 19-28 weeks | Functional return | CKC, plyometrics, sport-specific drills |
| 28-32 weeks | Full return | Unrestricted activity, weight training |
All exercises should be performed under guidance of a qualified physiotherapist or physician. Individual progression depends on fracture type, displacement, whether surgery was performed, age, and X-ray healing evidence. The protocol above is based on MGH Sports Medicine rehabilitation guidelines and standard orthopedic practice.
