Tendons are typically attached to the shoulder bone during a surgical procedure to repair a torn rotator cuff. This is most commonly done using suture anchors.
Here's a breakdown of the process:
The Rotator Cuff Repair Process
-
Preparation: The shoulder area is prepared, and the patient is positioned for surgery. This is often done arthroscopically, using small incisions and a camera.
-
Identifying the Tear: The surgeon identifies the torn tendon(s) of the rotator cuff.
-
Preparing the Bone: The area on the humerus (upper arm bone) where the tendon needs to be reattached is prepared. This might involve roughening the bone surface to promote better healing.
-
Suture Anchor Placement: Small anchors, called suture anchors, are inserted into the bone. These anchors have sutures (strong threads) attached to them. These anchors are typically made of metal or a material that dissolves over time.
-
Tendon Reattachment: The sutures from the anchors are then passed through the torn tendon. The surgeon carefully pulls the tendon back into its original position on the bone and secures it using the sutures. The sutures are tied down, effectively anchoring the tendon to the bone.
-
Closure: The incisions are closed, and the shoulder is immobilized.
Suture Anchors: The Key to Reattachment
- Function: Suture anchors act like tiny rivets, providing a secure point of attachment for the sutures that hold the tendon to the bone.
- Materials: Anchors can be made from:
- Metal: These are very strong and provide excellent initial fixation.
- Bioabsorbable Materials: These gradually dissolve over time as the tendon heals. This eliminates the need for a second surgery to remove the anchors.
- Benefits: Suture anchors provide a strong and reliable way to reattach the tendon, promoting healing and restoring shoulder function.
Important Considerations
- Arthroscopic vs. Open Surgery: Rotator cuff repair can be performed arthroscopically or through a traditional open incision. Arthroscopic surgery is less invasive and often results in a faster recovery.
- Rehabilitation: Following surgery, a comprehensive rehabilitation program is crucial to regain strength, range of motion, and function in the shoulder.
