Acromioclavicular (AC) Dislocation Repair Rehab Protocol
An acromioclavicular (AC) joint dislocation, or “separated shoulder,” is not truly an injury to the shoulder joint itself, but of the ligaments that attach the clavicle to the scapula. This injury commonly occurs from a direct blow to the shoulder such as a fall during sporting activity. A mild sprain involves the AC ligaments that attach the clavicle to the top portion of the scapula called the acromian. Severe injuries rupture both the AC ligaments as well as the coracoclavicular (CC) ligaments that attach the undersurface of the clavicle to the scapula. There is a sensation of a “sagging shoulder” as the weight of the arm pulls the scapula down away from the clavicle, causing a noticeable bump deformity the top of the shoulder. Mild sprains can be treated conservatively with rest, therapy, and time. More severe injuries require surgery to restore the anatomic relationship of the clavicle and scapula to optimize shoulder function.
The AC joint is reconstructed using a combination of strong sutures and buttons to restore the scapula height to the clavicle and in more chronic injuries a tendon graft may be necessary to reinforce the construct. Direct visualization and intraoperative x-ray help ensure adequate restoration AC joint. The goal of surgery is to restore the anatomic length of the clavicle to ensure return of shoulder motion and arm strength over time. This surgery can be performed as an outpatient, getting you home the same day.

Phase 1 (0 – 2 weeks postop)
Goals: Control pain, Diminish swelling, Protect the repair
- Pain: You will be prescribed pain medication to use after surgery. Use as directed and wean use to as needed. You may take an anti-inflammatory medication (i.e. ibuprofen, naproxen) as you wean from the narcotic. Do not drive or use alcohol while taking narcotic pain medication.
- Sling: A sling will be placed before you wake up from surgery. Keep the sling on at all times when up and about and when sleeping. You may remove your arm gently from the sling to move your elbow, wrist, and fingers when sitting in a controlled environment at home a few times a day. Avoid trying to lift your arm above 90°. Plan on using the sling for 4-6 weeks.
- Have someone help you remove and replace the sling. It is easier to wear button down shirts instead of pullover shirts. With the sling removed, hold your shoulder steady as if the sling were still on, slip your shirt over your arm and shoulder, and then have someone assist in replacing the sling and pillow.
- You may shower after the 3rd day, but stand keeping the shoulder away from the direct shower spray. To wash under your arm bend forward allowing the hanging arm to drift away from your body. Keep the incision site dry.
- Suture removal if needed
- Review of your surgery and rehab plan
Exercises
- Precautions:
- NO lifting objects
- NO sudden arm movements
- Arm, wrist, finger motion
- Remove arm from sling to bend your elbow, wrist, and fingers for 5 min 5x/day
- Pendulum exercises (begin on day 3)
- Gently remove sling, bend forward to allow your hanging arm to fall away from your body.
- Use your unaffected arm to rotate your operative arm in a circular motion and side to side. Your operative shoulder and arm should remain completely relaxed
- 5 min 5x/day
Phase 2 (2 – 6 weeks postop)
Goals: Control pain, Gentle shoulder motion, Protect the repair
- Sling: Use the sling at all times when up and about. Use caution when showering as outlined in Phase 1. You may wean out of the sling after 6 weeks.
- No lifting > 2 lbs, no forceful pushing or pulling. Avoid reaching behind your back.
- Pain: begin to wean off narcotic pain medication.
- Schedule a clinic visit about 6 weeks from your surgery date
Exercises
- Continue daily Pendulum exercise
- Lower extremity weight training and cardiovascular training for general health
- Supine Shoulder internal/external rotation
- 5 min 5x/day
- Supine passive forward flexion to 90°
- Lying on your back, raise your surgical arm by the wrist/elbow using your unaffected arm
- Table slides
- Place surgical arm on a magazine or other flat sliding object on a table, stabilize at wrist with unaffected hand to begin sliding motion. Hold for 10 sec. Retract by reclining body and using unaffected hand. Avoid lifting surgical arm off table.
- Scapula retraction
- Stick Exercises
- Use unaffected arm to gently push surgical arm in abduction, external rotation, forward flexion, extension, and internal rotation as shown below. Hold each stretch for 10 sec. Keep surgical shoulder relaxed throughout the motions.
- Goal by 6 weeks: passive motion to 90° of forward flexion/abduction, full internal/external rotation
- Goal by 12 weeks: full motion in each plane as your unaffected shoulder
Phase 3 (6-12 weeks postop)
Goals: Continue shoulder stretching, improve to full range of motion, protect the repair site, begin shoulder strengthening
- Sling: You may wean out of the sling. If you experience any increase in shoulder pain or feeling of fatigue, replace the sling to allow the shoulder to rest. You may remove the sling to sleep.
- No lifting or carrying objects > 5 lbs. You may use your arm for regular activities of daily living around the house.
- Schedule a clinic visit about 3 months from your surgery date
