Anterior Shoulder Instability Treated With a Semitendinosus Subscapular Sling Procedure
Norway15 participantsStarted 2017-12-20
Plain-language summary
The arthroscopic subscapular sling procedure is a new technique for shoulder stabilization, which has been developed in human cadaveric studies by Klungsøyr et al, but has yet to be tested clinically. The procedure stabilizes the shoulder by using a semitendinosus graft that makes a new labrum and a sling around the subscapular tendon. Extensive biomechanical robotic testing of the procedure shows significant less translation and thus better stability of the humeral head with the sling compared to a normal Bankart repair. The investigators consider the biomechanical results after robotic testing sufficient to advocate a planned pilot study in humans. In this pilot study the clinical and radiological results of the sling will be investigated in a small number of cases. The safety of the subscapular sling procedure will be assessed. This studies results are expected to be a further step towards implementation of the sling procedure as a surgical option for shoulder instability.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Clinical anterior instability of the shoulder and/or previous failed Bankart repair or arthroscopic findings concluding with too weak anterior structures to perform capsulolabral or labrum repair
* Be able to understand oral and written Norwegian /English
Exclusion Criteria:
* Cuff injury or previous cuff repair
* Surgical fracture treatment of the glenoid or humeral head
* Other instability procedures in the shoulder except Bankart repair and anterior capsular plications
* Previous infections in the shoulder
* MRI detectable fatty infiltration of the subscapularis or partial/total tendon rupture
* Severe glenohumeral arthrosis
* Multidirectional or posterior instability
* Not able to comply fully with the protocol due to psychosocial and physical conditions
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
