Open Versus Arthroscopic Stabilization of Shoulder Instability With Subcritical Bone Loss: The OASIS Trial

Overview

About this study

The purpose of this study is to investigate the effects of three surgical procedures and the associated post-operative rehabilitation to optimize time to return to military duty, work and sports, and patient-reported physical function for military personnel and civilians with traumatic anterior shoulder instability and 10-20% glenoid bone loss.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

- Civilians and military personnel ages 17 to 50

- Traumatic anterior shoulder dislocation

- Associated subcritical bone loss between 10-20% less the glenoid width quantified by
standard of care CT scan

Exclusion Criteria:

- Chronic, non-traumatic multi-directional instability based on clinical exam.

- Concurrent shoulder injury (e.g. rotator cuff tears, motor nerve pathologies,
osteoarthritis of a Samilson-Prieto grade >2).

- Prior instability or rotator cuff procedure on involved shoulder (including
intra-articular soft tissue surgery).

- Humeral sided bone lesion (Hill-Sachs lesion) that is sufficiently large enough to
render the lesion "off-track" even after a bony augmentation procedure would be
performed.

- Neuromuscular and other movement control pathologies including seizures.

- Vascular injury associated with the shoulder trauma.

- Traumatic brain injury or any condition that would preclude the ability to comply with
post-operative guidelines.

- Does not plan to return to pre-injury levels of work, sports or military duty.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Eligibility last updated 11/9/22. Questions regarding updates should be directed to the study team contact.
