An arm harness for applying at least one of distractive and abductive force to a human shoulder has at least two restrictor features mounted on a torso strap to be placed around a patient's waist. A first restrictor feature serves as a fulcrum at a restriction point on the arm spaced from the elbow to limit movement of the arm in one direction at the restriction point. The second restrictor feature applies force to the arm spaced both from the restriction point and from the elbow. In one embodiment, the first restrictor feature is positioned to limit movement of the forearm toward the shoulder, and the second restrictor feature applies force to the wrist to urge the wrist to move toward the shoulder, thereby applying axial distractive force to the shoulder joint. In another embodiment, the first restrictor feature is placed between the upper arm and the torso. The second restrictor feature urges the elbow toward the torso, thereby applying lateral distractive force to the shoulder joint. The two types of restrictor feature pairs may be combined in an arm harness that provides both axial and lateral distraction to the shoulder joint.

Systems, devices and methods to access and/or treat targeted body tissue (e.g., tendon tissue, ligament tissue, muscle tissue, bony tissue, and the like) under the guidance of ultrasound imaging equipment are described. Such systems can permit the intra-operative identification of the targeted tissue and the ability to deliver the appropriate instrumentation to that tissue.

Delivering ultrasonic energy to a target musculoskeletal tissue site includes connecting a delivery device to a vacuum source, a fluid source, and a power signal source. The delivery device has a housing portion maintaining an ultrasound transducer and a tip portion having a sleeve and a cannula. The cannula is coupled to the ultrasound transducer and received in the sleeve to define a covered portion and an exposed portion. Ultrasonic energy is generated by sending a power signal from the power signal source to the ultrasound transducer. The ultrasonic energy is transmitted from the ultrasound transducer to the cannula, such that the exposed portion of the cannula delivers ultrasonic energy at a frequency that is pre-selected to debride musculoskeletal tissue upon percutaneous insertion of the tip portion.

Permanent magnets are implanted in bone to unload compressive forces at joints using the repulsive force therebetween. A porous metal container is implanted first and becomes fixed in place by bone growth. The permanent magnet is then inserted in the container and retained in place. A magnet prescription system includes a display and input device which enables a user to alter parameters such as magnet size, strength and placement and calculate and display the repulsive force that will result.

Finger splints for use in connection with distal interphalangeal (DIP) joint fractures are disclosed. The splints include a ring element for positioning around a finger at a location proximal to the distal interphalangeal (DIP) joint and include an extension member that extends over the DIP joint and attaches to the fingernail.
