Understanding the Subcapsular Space in Shoulder Replacement Surgery

The subcapsular region refers to the area beneath the capsule of a joint, such as the shoulder or knee. In the context of orthopedic surgery, the subcapsular space is the area between the capsule and the surrounding bone or soft tissue.

In the case of a shoulder replacement, the subcapsular space is the area beneath the capsule of the shoulder joint, where the prosthetic component is placed. The prosthetic component is attached to the bone using bone cement or a porous surface that allows for bone growth.

The subcapsular space is an important area in shoulder replacement surgery because it provides a stable and secure location for the prosthetic component, allowing for proper functioning of the joint. Additionally, the subcapsular space is often used as a site for injecting medications or contrast dye during imaging procedures.
