Key points

  • Wear the brace during the first 5 weeks except during rehabilitation exercises. It can be discontinued at weeks 5–6.
  • Postoperative week 4: Active-assisted range of motion
  • Postoperative week 8: Resistance exercises
  • Postoperative week 14: Pectoralis major strengthening
  • Manual work can begin once 3 months have elapsed. After 3 months, activities such as horse riding, football, swimming, martial arts and climbing can gradually resume.

Planning your rehabilitation

This postoperative rehabilitation guide should be followed under medical supervision and adapted to the individual patient.

Wound care and icing

Keep the wound dry. Avoid direct water exposure and showering early after surgery. Once some recovery has taken place, the wound can be covered with plastic wrap for protection when showering.

Change the dressing every 2–3 days. Sutures are removed at about 2 weeks, at the surgical outpatient clinic or a local hospital.

Wrap an ice pack or frozen items in a clean, dry towel to avoid direct skin contact. Apply for no more than 15 minutes, leaving at least 2 hours between applications. Continue while swelling remains; icing can also be used for swelling or pain after rehabilitation exercises.

Sling or brace protection

Wear the brace during the first 5 weeks except during rehabilitation exercises. It can be discontinued at weeks 5–6.

Postoperative week 1: Hand, wrist, and elbow movement

Ball squeeze

Squeeze a tennis ball or rolled-up sock for 6 seconds, then relax for up to 10 seconds.

For each exercise: 10 repetitions per set, 3 sets daily.

Postoperative week 4: Active-assisted range of motion

For each exercise: 10 repetitions per set, 3 sets daily.

Stick-assisted shoulder flexion

Lie on your back, holding a stick or cane with both palms facing up. Slowly raise it overhead, then lower it.

Stick-assisted external rotation

Lie on your back with both elbows bent to 90°, holding the ends of a stick. Use the unaffected arm to guide the operated arm outward, keeping its elbow close to your side.

Towel-assisted elevation

Start with the elbows bent and hold a towel with the palms facing up. Raise it as high as possible, using as much help as possible from the uninjured or non-operated side.

Postoperative week 6: Active range of motion

For each exercise: 10 repetitions per set, 3 sets daily.

Wall climb

Stand facing a wall with the toes about 30 cm away. Place both sets of fingertips on the wall and slowly walk them upward, keeping the arms parallel; repeat several times. Then stand sideways with the operated shoulder toward the wall and move the fingers upward with the shoulder abducted. Move closer as the range improves.

Side-lying external rotation

Lie on your side with a yoga block or other support between the arm and body so the upper arm is roughly parallel to the floor. Bend the elbow to 90° and draw the shoulder blade slightly inward. Keeping it stable, rotate the arm upward into about 80–90° of external rotation, then return.

For each exercise: 10 repetitions per set, 3 sets daily.

Supine shoulder lift

Lie on your back with the elbow straight. Elevate the shoulder blade and reach the upper arm upward. Hold for 5 seconds, then relax.

After postoperative week 12: Resisted internal rotation

After 12 weeks, begin with light resistance and progress under your surgeon’s or physiotherapist’s guidance according to healing, pain and strength recovery.

Band internal rotation

Keep the elbow close to the trunk and slowly rotate the forearm inward against the resistance of an elastic band.

Bench press

Lie on a bench and hold a barbell. Press upward from the chest until the arms are straight, then lower with control to approximately 90° of elbow flexion. Keep the trunk stable and a slight natural arch in the back.

Return to sport

Manual work can begin once 3 months have elapsed. After 3 months, activities such as horse riding, football, swimming, martial arts and climbing can gradually resume.

Return to sport requires adequate rehabilitation and muscle strength. Exercising before strength has recovered may reinjure the pectoralis major. Recovery varies between individuals; discuss the detailed schedule with your surgeon at follow-up.
