Shoulder Bone Block & Allograft Reconstruction

What is a shoulder instability and what causes it?

A shoulder dislocation can be a traumatic and painful injury. It occurs when the ball of the upper arm (humerus) is forced fully out of its normal position within the shoulder socket (glenoid labrum.) This can happen partially, call a subluxation, or completely, called a dislocation, and often requires a reduction (when the bone is located back into the correct position.)  Once a shoulder has been dislocated, the ligaments and Lining of the joint become stretched, resulting in a high risk of recurrent dislocations and shoulder instability. Dr. Nikhil Verma, orthopedic shoulder surgeon specializes in shoulder instability and can help patients in Westchester, Oakbrook, Hinsdale and surrounding Chicago communities who are suffering from recurrent dislocations, or shoulder instability.

Have you sustained a dislocated shoulder?

There are two ways to initiate a consultation with Dr. Verma:

You can provide current X-rays and/or MRIs for a clinical case review with Dr. Verma ($250).

You can schedule an office consultation with Dr.

What is glenoid bone loss?

The glenoid, or flat part of the scapula (shoulder blade) is an important part of the shoulder joint. The glenoid has a rim of cartilage, called the labrum, which helps hold the humerus (long arm bone) within the shoulder joint. If a patient has glenoid bone loss, recurrent shoulder dislocations are common. There are several reasons for glenoid bone loss which can include:

  • Recurrent Traumatic shoulder dislocation
  • Fracture of the glenoid

What is a bone block?

Dr. Nikhil Verma, orthopedic shoulder surgeon offers a treatment option for patients in Westchester, Oakbrook, Hinsdale and surrounding Chicago communities who have glenoid bone loss. This innovative treatment is called a bone block, or allograft reconstruction. It utilizes a composite piece of bone and cartilage to reinforce the glenoid “socket” which holds the humerus (upper arm bone) in place.

What is an allograft?

An allograft is simply defined as donor tissue. In the case of shoulder instability and a bone block procedure, an allograft is used (harvested) from a donor. All donors are screened appropriately for any communicable diseases and because the bone and cartilage does not contain a high volume of living cells, no immune suppression medications are required. The use of allograft in orthopedic surgery has a long history of success and safety. The piece of bone is screwed into place with two screws, creating the desired bone block. Allografts are desirable, especially in cases where the patient is very active but has 20% or more glenoid bone loss.

Does an allograft bone block work for shoulder instability?

Studies have shown excellent outcomes from bone block allografts, often combined with a Bankart repair (procedure that repairs the cartilage on the glenoid.) Dr. Verma has been successful with this procedure, finding that it restores range of motion, eliminates instability, allowing athletes a high rate of return to competitive sports. In addition, follow up studies with CT scan imaging have shown very high rates of healing and incorporation of the allograft bone.
