The implant assembly may include a head, a cup, a humeral stem and an adapter. The method includes inserting the humeral stem to the humerus and connecting a male taper of the adapter to a female taper of the head. For reverse arthroplasty, the method includes attaching the adapter to the glenoid and the cup to the stem. For traditional arthroplasty, the method includes attaching the adapter to the humeral stem and the cup to the glenoid. The method also includes articulating the head with the cup.

A method of performing a shoulder joint surgery involving a scapula having a glenoid cavity, a humerus and a humeral ball on a surgical table includes mounting a retractor support to the surgical table and positioning the retractor support about the shoulder joint. The skin and flesh layers proximate the shoulder joint are incised and the skin and flesh layers are manually retracted with a retractor. The retractor is secured in a selected position by attaching the retractor to the retractor support.

The present invention relates to an exoskeleton interface apparatus that parallels human arm motion and is comprised of a serial assemblage of five powered linkages and joints based at a rigid support structure worn on the torso of the human subject. Such apparatus generates shoulder rotation using three orthogonal revolute joints mounted on serial linkages encompassing and intersecting at the anatomical glenohumeral joint. Elevation of the shoulder joint is articulated using a link member driven by a single revolute joint mounted in the torso structure. Passive adjustable linkages are used to match variation in anatomical forearm length, upper arm length, and scapula-to-glenohumeral radius. A plurality of integrated dc motor/harmonic drive transmission modules is co-located on adjoining linkages to power the joints. Force is exchanged with the human at the handgrip and elbow brace, and reacted to the torso structure via the base attachment. The present invention is applicable in particular to rehabilitation of the shoulder.

A fluid operated retractor for use in surgery. The retractor has a portion which is expandable upon the introduction of fluid under pressure. The expandable portion is made of a material strong enough, and is inflated to enough pressure, to spread adjoining tissues within the body. The retractor is especially useful in fiber optic surgery because it can be inserted percutaneously through a small opening then expanded to a much larger dimension when in the desired location, to retract tissue from within. The retractor may be used to spread a joint such as a knee joint or a shoulder joint, or may be used to separate tissue planes generally, to improve visualization and create a working space for the surgeon.

A separate section is introduced between the sleeve and the body of any garment such as a jacket, parka, wind shirt, or shirt of any type to isolate, to a considerable extent, the motion of the sleeve from the main body of the garment. This isolation of movement is accomplished by shaping the edges of the separate section and the adjoining edges of the garment body and the sleeve in such a way that excess fabric is available between the sleeve and the body of the garment regardless of which direction the arm is moved. In particular, excess fabric is available to accommodate the volume of the shoulder joint when it moves upward from a rest position as the arm is raised. The result is that the wearer can move the arm over a very wide range of motion with much less movement of the main body of the garment and much less movement of the sleeve cuff up and down the arm than with other methods of sleeve attachment.
