Shoulder immobilizer and arm apparatus
A shoulder immobilizer and arm apparatus are provided for enhanced comfort and ease of use for rehabilitating a shoulder. The shoulder immobilizer includes a double figure-9 strap configuration to support the weight of an injured arm and shoulder comfortably. The shoulder immobilizer can be stepped down for modular construction and use depending on a user's needs. The shoulder immobilizer may be configured to cooperate with a corresponding arm apparatus, including an open-frame sling allowing for elbow extension and a simplified strap configuration.
1. A shoulder immobilizer adapted to immobilize a shoulder of a user and to connect to an arm apparatus, comprising:
a first portion defining a loop adapted to extend about a contralateral shoulder;
a second portion including a first belt adapted to extend along an anterior side of the user from a first end of the first portion, and a second belt adapted to extend along a posterior side of the user from a second end of the first portion, the first and second belts arranged for connecting to one another, the first and second belts arranged to couple to one another on an anterior side of the user;
wherein the second portion is arranged to secure to the arm apparatus;
wherein the first portion comprises first and second segments forming said loop;
wherein the first and second segments join at an inferior junction adapted to be positioned at a location proximate a contralateral elbow;
wherein the first portion and the first belt forms a first “figure-9” strap configuration arranged to extend in the loop about the contralateral shoulder from the inferior junction superiorly over an anterior portion of the contralateral shoulder and about a posterior portion of the contralateral shoulder inferiorly directed to the first belt directed about an anterior side of the user.
2. The shoulder immobilizer of claim 1 , wherein the first and second belts extend from the second and first segments, respectively, and are arranged at an oblique angle relative to one another.
3. The shoulder immobilizer of claim 1 , wherein the first and second segments extend and intersect through a pad generally located about the inferior junction.
4. The shoulder immobilizer of claim 1 , wherein the first and second belts extend from the inferior junction at generally a same height.
5. The shoulder immobilizer of claim 1 , wherein the second segment is adapted to be arranged relative to the first belt about the contralateral shoulder when the shoulder immobilizer is tensioned such that a third force superiorly exerted by the second segment counteracts a second force inferiorly exerted by the first belt about the contralateral shoulder.
6. The shoulder immobilizer of claim 5 , wherein the first segment is adapted to be arranged relative to the second belt about the contralateral shoulder when the shoulder immobilizer is tensioned such that a first force superiorly exerted by the first segment counteracts a fourth force inferiorly exerted by the second belt about the contralateral shoulder.
7. The shoulder immobilizer of claim 6 , wherein the first force extends obliquely opposite to the third force.
8. The shoulder immobilizer of claim 6 , wherein the second force extends obliquely opposite to the fourth force.
9. The shoulder immobilizer of claim 1 , wherein the second portion further comprises an anterior strap attachable to the first segment and arranged to secure to the arm apparatus.
10. The shoulder immobilizer of claim 9 , wherein the anterior strap attaches to the first segment at a location superior of the inferior junction.
11. The shoulder immobilizer of claim 10 , wherein the anterior strap includes a first strap portion connecting to the second segment by a first height adjuster and to the arm apparatus by a connector, the anterior strap having a second strap portion extending from the connector and detachably securing to the first strap portion to adjust a length of the anterior strap.
12. The shoulder immobilizer of claim 11 , wherein the second portion further comprises a posterior strap attachable to the second segment and arranged to secure to the arm apparatus;
wherein the posterior strap attaches to the second segment at a location superior of the inferior junction.
13. The shoulder immobilizer of claim 12 , further comprising a posterior panel connecting the second belt to the posterior strap;
wherein the posterior panel is a flexible textile extending between the second belt and the posterior strap.
14. The shoulder immobilizer of claim 13 , wherein the posterior panel is a plate having rigid or semi-rigid properties;
wherein the second belt slidably extends through the plate through at least one retainer or slot.
15. The shoulder immobilizer of claim 14 , wherein the posterior strap slidably extends through the plate through the at least one retainer or slot;
wherein the plate has a profile adapted to extend along a spine of the user.
16. The shoulder immobilizer of claim 11 , wherein the first height adjuster includes a slider connected to the first segment and a coupler slidably engaging the slider, the coupler engaging the anterior strap.
17. The shoulder immobilizer of claim 1 , further comprising:
the arm apparatus including a main body defining an upper arm region, an elbow region and a forearm region, the elbow region having an opening located between the upper arm region and the forearm region.
18. The shoulder immobilizer of claim 17 , wherein the arm apparatus includes an extension attached to the forearm region.
19. The shoulder immobilizer of claim 17 , wherein the forearm region generally extends perpendicularly relative to the upper arm region.
20. The shoulder immobilizer of claim 17 , wherein the upper arm region defines a generally semi-circular profile, the upper arm region forming a posterior flange and/or and anterior flange extending along at least part of the generally semi-circular profile.
