Sling vs. Dynamic Shoulder Stabilizer After Soft Tissue Shoulder Instability Surgery ("SLIDY"): A Pilot Randomized Controlled Trial Assessing Feasibility, Early Functional Recovery, and Structural Healing

This randomized controlled trial seeks to address a significant clinical gap by evaluating the outcomes of two postoperative immobilization methods following arthroscopic soft tissue surgery for anterior shoulder instability: a standard static arm sling and a dynamic shoulder orthosis.

Detaljeret beskrivelse

The present study is a pilot trial that aims to compare outcomes between patients immobilized using a standard arm sling and those managed with a dynamic shoulder orthosis (specifically, the medi® Shoulder action brace) following arthroscopic soft tissue stabilization for anterior shoulder instability. This trial will evaluate the impact of these two immobilization methods on early shoulder function, pain, recurrence, and patient satisfaction, while primarily assessing the feasibility of a future definitive trial. This is a prospective, single-center, pilot randomized controlled trial with parallel groups. Participants will be allocated in a 1:1 ratio to either the dynamic orthosis or the standard sling. The trial seeks to determine whether dynamic immobilization designed to facilitate controlled activity offers measurable advantages in early function, comfort, or recurrence risk compared to standard arm slings.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Dynamic Immobilizer
Continuous wear of the dynamic shoulder orthosis for 3 weeks post-surgery, followed by a standardized physiotherapy protocol.
Enhed: Dynamic Immobilizer
An adjustable strap system applied immediately post-surgery that permits movement of the shoulder joint while simultaneously limiting potentially harmful ranges of motion and translations. It is worn continuously for 3 weeks.
Andre navne:
  • medi® Shoulder action brace
Aktiv komparator: Standard Arm Sling
Continuous wear of a conventional fabric arm sling for 3 weeks post-surgery, followed by a standardized physiotherapy protocol.
Enhed: Conventional fabric arm sling
Static immobilization using a conventional fabric arm sling applied immediately post-surgery and worn continuously for 3 weeks.
