A shoulder immobilizer () includes a semi-rigid or rigid orthosis, in the form of an arm support (), which supports the upper arm, elbow, forearm and wrist of a patient. A bolster () is positioned between the patient and the arm support (). A body strap () extends around the patient and attaches to the arm support () and/or the bolster (), holding the arm support and bolster in position against the body of the patient. In embodiments, the shoulder immobilizer () may utilize a shoulder strap (), but such a shoulder strap is not necessary for shoulder immobilization of the patient.

Shoulder immobilizer and fracture stabilization device

Tension members anchored to a wearer's body to resist femoral acetabular impingement (FAI)-causing movements. A first tension member is anchored to the body of a subject, and produces a force on the subject's body to primarily limit the ability of the subject's thigh to internally rotate and the ability of the subject's knee to adduct. Thus, this first tension member resists the tendency of the subject's leg to twist inward or deflect inward, each of which may contribute to FAI. A second tension member is anchored to the subject's body, and provides a force to the subject's body to primarily limit the ability of the subject's hip joint to move in flexion. Thus, the second tension member resists the tendency of the subject's leg to raise too high, which may also contribute to FAI.

A joint distraction device for use in an arthroscopic surgery is provided. The device has a joint distraction mechanism, situated in between two bone fixation surfaces, and is capable of changing the relative distance between these two surfaces. The force generated by the mechanism should be sufficient to insert bone spikes affixed to the surfaces into bone, as well as distract the joint to create a sufficient enough gap to allow the intended procedure. With the surfaces and spikes engaged to bone at opposite sites of a joint, an increase in distraction force results in an increase in the relative distance results, hence increasing the space within the joint. Embodiments of this invention, compared to fracture table approaches, effectively eliminate the risk of pudendal nerve injury, allow for longer surgical times, and allow for much more controllable joint distraction.
