Arm sling and stabilization device

A sling comprising:

• a base vest having a back portion joined to a right front side having a right arm opening and a left front side having a left arm opening and a neck opening;
• an arm holder formed in or attached to the base vest and comprising a forearm support which forms a tunnel having a front opening and a back opening;
• an adjustable restraint which is joined on a first end to the arm holder or the front portion of the base vest and on a second end to the arm holder or to the back portion of the base vest so as to form a closed loop to secure an elbow of a wearer in a position in the arm holder allowing a forearm to be inserted with an upper arm hanging in line with a torso of the wearer with an axis of an upper arm aligned parallel +1-10° to a coronal plane and the forearm at an angle of 90°+/−15° to the axis of the upper arm whereby the weight of the forearm is distributed through the vest to a back and a chest of the wearer;
• a flap attached to the base vest to allow the forearm support to be positioned so that the forearm is situated at the angle of 90°+/−15° to the axis of the upper arm and having a section of hook and loop fastener on a surface that opposes a base vest right or left front portion and the base vest including a section of hook and loop fastener facing outward and extending parallel to the flap;
• a first foam block with a cross section of a trapezoid and having a top surface joined to a back surface at an angle of from 30 to 85° and configured on the top surface to support the forearm and having a length of 10 to 15 inches, a width of 3 to 5 inches, and a height of from 5 to 8 inches at a front surface and from 5 to 8 inches at the back surface, the back side of the block including a section of hook and loop fastener which is capable of mating with the hook and loop fastener on the flap;
• and
• a second foam block having a bottom surface corresponding in shape and angle to the top surface of the first foam block, and a side surface configured to mate with a front surface of the first foam block such that the second foam block is fully supported, and a bottom surface of the second foam block has a section of hook and loop fasteners that mate with a section of hook and loon fasteners on the top surface of the first foam block,
• wherein the tunnel has a length of 10 to 15 inches and has a front side and a back side which has a section of hook and loop fastener which is capable of mating with the hook and loop fastener on the flap so as to support the tunnel by the flap.
