Shoulder Avascular Necrosis Surgical Treatments
What are the surgical options for AVN?
In cases of AVN where conservative treatments are not sufficient, surgical interventions may be considered. Here are some surgical options for AVN of the shoulder:
A minimally invasive procedure that involves drilling a hole into the humeral head to relieve the pressure within the bone. The decreased pressure allows the vasculature to re-supply the damaged bone. This procedure also creates new channels for blood vessels to supply nutrients and oxygen to the dead bone. Core decompression is most effective in cases that are diagnosed early before the humeral head collapses.
Replacement of the dead bone and damaged cartilage with healthy bone and cartilage from another bone in the body (autograft) or from a donor (allograft). This procedure replaces the defect, provides mechanical support, and re-introduces a smooth cartilage joint surface. Stem cells are often extracted from other parts of the body and injected into the shoulder joint during this procedure to promote bone and cartilage healing as well as reduce inflammation.
The most effective treatment in late-stage cases of AVN where the bone has already collapsed. This procedure involves removing the damaged bone and replacing it with prosthetic implants that restore the function of the shoulder joint. This procedure is performed by a joint replacement surgeon. If you are diagnosed with AVN and humeral head collapse, Dr. Chahla will refer you to a trusted joint replacement surgeon to learn more about the replacement options available to you.
The choice of surgical intervention depends on the severity of AVN, the extent of joint damage, and the patient’s overall health. Dr. Chahla will assess these factors and recommend the most appropriate surgical option for each individual case.
