Understanding AC Joint Injuries
What is the AC Joint?
The acromioclavicular (AC) joint is where the clavicle (collarbone) and acromion (part of the scapula) meet. It provides stability and flexibility for arm movements.
Common Causes of AC Joint Injuries
- Trauma: Direct impact from falls or collisions (common in contact sports like football and hockey)
- Overuse: Repetitive overhead motions (seen in weightlifting and swimming)
- Degenerative Conditions: Osteoarthritis or chronic wear and tear
AC Joint Injury Grades
- Grade 1: Mild sprain, minimal ligament damage
- Grade 2: Partial ligament tear, moderate pain
- Grade 3: Complete ligament tear, visible deformity
- Grade 4-6: Severe injuries requiring surgical intervention
AC Joint Rehab Protocol
Phase 1: Acute Phase (0-2 Weeks)
Goals: Reduce pain, inflammation, and protect the joint
- Rest & Immobilization: Use a sling if recommended by a doctor
- Ice Therapy: Apply ice for 15-20 minutes every 2-3 hours
- Pain Management: NSAIDs (if approved by your healthcare provider)
- Gentle Range of Motion (ROM) Exercises: Start pendulum exercises and light arm movements as tolerated
Phase 2: Early Rehab (2-6 Weeks)
Goals: Improve mobility and begin strengthening
- Stretching Exercises:
- Passive shoulder flexion and extension
- Cross-body shoulder stretch
- Isometric Strengthening:
- Isometric shoulder abduction and external rotation
- Posture Correction: Maintain proper shoulder alignment
- Continue Ice Therapy: As needed for pain relief
Phase 3: Strength & Stability (6-12 Weeks)
Goals: Restore full range of motion and increase strength
- Progressive Strengthening Exercises:
- Resistance band external and internal rotations
- Dumbbell shoulder raises (front and lateral)
- Scapular stabilization exercises
- Functional Movements:
- Push-ups (modified to full as tolerated)
- Controlled overhead reaching movements
- Balance & Proprioception Training:
- Single-arm planks
- Stability ball exercises
Phase 4: Return to Activity (12+ Weeks)
Goals: Prepare for sports and daily activities
- Sport-Specific Drills: Gradually introduce high-intensity movements
- Full-Body Strength Training: Incorporate compound movements for overall stability
- Plyometric Exercises:
- Medicine ball throws
- Plyo push-ups
