How Long Do You Have to Wear a Sling After a Shoulder Injury?

Why a Sling Is Used in the First Place

A sling does two things. It supports the weight of the arm so the injured structures do not have to, and it limits movement to prevent further damage during the early stages of healing. Some injuries need a lot of immobilization, while others just need a short period of rest before gentle movement can begin.

The type of injury and whether surgery was involved are the two biggest factors that determine how long the sling stays on.

Sling Timelines for Common Shoulder Injuries

Here’s what you need to know if you are concerned about wearing a sling for a long time:

• Shoulder Dislocation

After a first-time shoulder dislocation, most patients wear a sling for one to three weeks. The sling keeps the shoulder in a stable position while the stretched ligaments and capsule begin to heal.

Starting physical therapy to rebuild strength and stability around the joint usually begins shortly after the sling comes off. For patients who have had multiple dislocations or who have undergone surgical stabilization, the timeline is longer.

• Rotator Cuff Tear

This is where sling duration varies the most. Small tears that do not require surgery might need the use of a sling for several weeks after the pain decreases and healing starts.

In cases where surgery is required to repair the damage done to the rotator cuff muscles, the use of a sling will continue for four to six weeks and even longer based on the extent of the tear and its size.

• Shoulder Fracture

Fractures around the shoulder, including the clavicle and proximal humerus, are often managed in a sling for four to six weeks. The exact duration depends on the severity of the fracture, whether it was displaced, and whether surgery was needed to fix it.

More complex fractures that require plates and screws may have a different rehabilitation timeline than fractures managed without surgery.

• Shoulder Surgery

Any surgical procedure on the shoulder typically involves a period of sling use afterward. Arthroscopic procedures for labral tears or impingement may require a sling for two to four weeks.

More involved surgeries like rotator cuff repairs or instability procedures generally require four to six weeks in a sling. Shoulder replacement surgery also involves a period of immobilization followed by a carefully structured rehabilitation program.

Why You Should Not Rush Coming Out of the Sling

It is tempting to ditch the sling as soon as the arm feels better. Pain settling down is a good sign, but it does not mean the underlying tissue has fully healed.

Coming out of the sling too early can put stress on structures that are not ready for it. This stress can set back recovery significantly or, in some cases, cause re-injury.

The sling timeline your surgeon gives you is based on what the tissue needs to heal properly, not just on how you feel day to day.
