Treatment of shoulder dislocation in the acute phase and in the rehabilitative recovery of the first event. Prevention of dislocation and subluxation of the shoulder pre- and post-surgery in the context of anterior glenohumeral instability.
ELASTICATED STRAP to restrict external arm rotation and abduction to prevent dislocation and subluxation of the shoulder.
COMPRESSION VEST to promote transpiration and heat regulation for greater comfort.
STRAP FOR SUPPORT AND RETROPULSION
of the humeral head aimed at ensuring the correct position of the shoulder
COMBINED ZIPPER AND HOOK AND EYESYSTEM
for improved wearability.
MODE OF ACTION
Rather than impeding movement, thanks to its four innovative mechanisms of action the S2 restricts and controls external shoulder rotation and abduction, offering the patient a complete feeling of safety.
The end section of the elasticated spiral strap (strap A) counteracts the abduction movement.
From a physical point of view, it acts in the same way as a series of levers, where:
1) the fulcrum (f) is represented by the centre of the humeral head;
2) resistance (R) is sited at the deltoid;/li>
3) power (P) is located at the tendinous insertions of the abductors of the humerus (supraspinatus and deltoid).
KEY: f = fulcrum – R = resistance – P = power
The elasticated spiral strap is fastened to the wrist and the opposite side of the chest. The centre of rotation is represented by the axis of the arm.
From a physical point of view:
1) F is the force exerted for external rotation of the arm versus its f axis. The moment around the fulcrum (f) is M=F*L, where L is the range of the limb;
2) The resistance R exerted by the strap causes internal rotation, whose moment versus f is M1=R*L;
3) The two moments (M and M1) are equal when the point of maximum permitted external rotation (end position) is reached, when F=R;
4) R increases as the elasticated spiral strap is tightened, thereby reducing the angle of external rotation.
KEY: f = fulcrum – F = force – R = resistance – P = power – M, M1 = moment – L = range of the spiral (range of the limb)
HUMERAL HEAD STABILISATION
The “hammock” strap (strap B), which passes under the armpit and is fastened to the opposite shoulder, exerts a pressure that pushes the humerus upwards and backwards, preventing anteroinferior dislocation.
The compressive action of the fabric, together with the silicone edging of the mesh, encourage shoulder mobility.
