About this trial

Anterior shoulder dislocations occur when the humeral head translates anterior to the glenoid cause pain, stiffness, and glenoid bone loss. If left untreated, the risk of recurrence can be up to or greater than 90%. The only surgically modifiable factor to reduce the risk of recurrence is the glenoid bone loss (GBL), where surgeons have the ability to recreate the shape of the glenoid and reduce the risk of recurrent shoulder dislocations.

Established boney procedures for shoulder instability include the Latarjet and free bone block procedures, such as the Anatomic Glenoid Reconstruction (AGR). The Latarjet is well known for its lower rate of recurrent instability, but raises concerns due to under-appreciated complications rates. The AGR is a newer surgical approach that has garnered attention for its low rate of recurrent instability and complication profile. Both treatments can reduce pain, increase function following surgery and reduce the risk of recurrent instability. However, these two established approaches have yet to be directly compared and studied on a larger scale.

The purpose of this randomized control trial is to compare clinical and radiographic outcomes pre- and post-operatively between the Latarjet to the AGR.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Patients with one or more instances of anterior shoulder dislocation; pre-operative CT scan illustrating >20% bone loss.

Disqualifiers

posterior shoulder instability; multidirectional shoulder instability; massive rotator cuff teats (MRI proven); history of substance abuse, patients unable to provide informed consent, patients refusing randomization.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Coracoid Transfer

    Procedure/Surgery

    For patients randomized to the active comparator group, the coracoid process and conjoined tendon will be cut and transferred to the anterior rim of the glenoid through an incision in the subscapularis muscle.

  • Distal Tibia Allograft with Bankart repair

    Procedure/Surgery

    For the experimental group, a distal tibia allograft will be prepped, cut (20mm x 10mm x 15mm), and inserted into the anterior aspect of the shoulder through a far medial portal. The distal tibia allograft will be attached to the anterior glenoid using cannulated screws. A soft tissue repair, Bankart repair, is performed above the graft.

Trial outcomes

Primary outcomes

1

Complication reporting

Complications reported any time from surgery to post-surgery will be compared.

Time frame
2 years

Secondary outcomes

1

Recurrent Instability

The rate of recurrent instability, dislocation and/or subluxation will be compared up until 2 years following surgery.

Time frame
2 years
2

American Shoulder and Elbow Surgeon (ASES) Assessment Form

Pain and function questionnaire for patients with shoulder injury. The scores will be out of 100, and a higher score equates to a better score.

Time frame
1 and 2 years
3

Western Ontario Shoulder Instability (WOSI) Index

Physical symptoms, emotions, and lifestyle questionnaire specific to patients with shoulder instability. The scores will be out of 100 and a lower score equates to a better outcome.

Time frame
1 and 2 years
4

EQ5D-5L

Includes 5 questions on mobility, self care, pain, usual activities and psychological status, a summary index is used to derive the outcomes, where a score of 1 indicates the best health. This questionnaire includes a visual analog scale, to indicate overall health out of 100. A score of 100 indicates the best health.

Time frame
1 and 2 years
