The summary below is from an episode of ERcast: Clinical Perspectives

After successful anterior shoulder reduction, prolonged immobilization does not reduce recurrence and can worsen stiffness. Post-reduction care hinges on brief sling use, early protected motion, and timely orthopedic or sports medicine follow-up to preserve function and reduce chronic instability.

Post-Reduction Shoulder Care

Brief sling immobilization: Standard sling with or without a swathe is appropriate after reduction, but immobilization should be limited to 1 week because longer sling time has not shown added protection against recurrence.
Swathe for early comfort: A swathe can help pain control immediately after reduction, but continuous use is best kept to 1-2 days before stepping back to allow gentle shoulder motion and reduce stiffness risk.
Early protected motion: Hand, wrist, and forearm motion should start right away, and passive pendulum exercises help prevent adhesive capsulitis while the shoulder itself remains protected from re-dislocation.
Movements to avoid: Aggressive external rotation, active abduction, and overhead activity are the main early red flags because they stress the healing anterior structures. We get into the practical restrictions in the episode.
External rotation debate: External-rotation bracing with an abduction pillow has some supportive data for recurrence prevention, but poor comfort and compliance have kept the traditional sling as the usual real-world choice.

Follow-Up and Recurrence Prevention

Early specialist referral: All patients with a shoulder dislocation deserve orthopedic or sports medicine follow-up, ideally within 7-10 days, because delayed definitive care is linked to worse long-term stability.
Physical therapy timing: Physical therapy started within 7-10 days can help preserve range of motion and lower the risk of frozen shoulder after a period of brief immobilization.
Young active surgical benefit: Young, active patients are more likely to benefit from primary surgical stabilization, with better functional outcomes and lower recurrence than watchful nonoperative care alone.
Early surgery matters: Time from first dislocation to surgery tracks with recurrence risk, so early referral matters most in patients likely to need operative stabilization. That timing nuance is worth hearing in the chapter.
Frequent dislocator counseling: Patients who repeatedly self-reduce may seem fine in the short term, but recurrent instability carries real risk of osteoarthritis, chronic pain, and labral injury over time.
Self-reduction teaching: For selected recurrent dislocators, the Boss-Holzach-Matter technique is a named self-reduction method worth knowing while they pursue definitive prevention strategies with a specialist.
