Shoulder Dislocation
About this trial
This is an interventional treatment trial for Shoulder Dislocation
Eligibility Criteria
Inclusion Criteria:
- Males and females between the ages of 12 and 18, inclusive
- Patients with a first-time traumatic anterior glenohumeral dislocation within the past 3 months
- Anterior glenohumeral dislocation confirmed by radiography, reduction required by medical personnel, or demonstration of anterior apprehension on physical examination following injury to the shoulder
- MRI or MRA demonstrating disruption of the glenohumeral soft tissues (including the labrum, periosteum, or inferior glenohumeral ligament) relating to instability
- Patients who have the ability to speak, understand, and read English
- Provision of informed consent (age 18) or parental consent (ages 12-17, inclusive)
- Provision of informed child assent (ages 12-17, inclusive)
Exclusion Criteria:
- Previous dislocation episodes or instability of the affected shoulder
- Previous surgeries involving the affected shoulder
- History or clinical exam findings of generalized ligamentous laxity (defined as a Beighton score of 4 or more points)
- History of multi-directional instability of either shoulder
- Concomitant fracture of the tuberosity, humerus, or glenoid (excluding a Bankart or Hill Sachs lesion)
- Bony Bankart lesion exceeding 15% of the glenoid surface (using the best-fit circle method on MRI)
- Hill Sachs lesion exceeding 15% of the humeral diameter (Measured on transaxial slice of MRI similar to Salomonsson et al.)
- A neurological injury of the affected arm
- Patients who will likely have problems, in the judgement of the investigator, with maintaining follow-up
- Any other reason(s) the investigator feels is relevant for excluding the patient

Arthroscopic stabilization
Rehabilitation including a period of immobilization followed by physical therapy
Patients will have an initial evaluation with a diagnostic shoulder arthroscopy and examination under anesthesia will be performed to confirm the degree of anterior instability and assess range of motion of the affected shoulder. Diagnostic arthroscopy will commence with the use of 3 standard shoulder portals (posterior viewing and two anterior working portals for suture passing), and a detailed arthroscopic examination will be performed. Once the soft tissue tear (including the labrum, and capsule labrum ligaments) is identified, it will be mobilized using a rasp or elevator and a burr will then be used to create a surface for a bleeding bone bed. Capsulolabral repair will then commence with the labrum fixed to the glenoid using suture anchors (the Bankart repair). Following surgery, subjects in this group will follow the same rehabilitation protocol as the comparison group.
Subjects in this group will use an internal-rotation shoulder immobilizer, using a standard sling for 6 weeks from the day of enrollment. Subjects will be advised to maintain range of motion (ROM) in the elbow and wrist during this period of time. The immobilizer can be removed for passive pendulum exercises and elbow ROM during the period of immobilization up to 4 times per day. Formal physiotherapy commences at 4 weeks post-enrollment, with a goal of return to activities or sport at 6-months post-enrollment.
