Systems and methods are provided for treating chronic pain occurring secondarily to subacromial impingement syndrome in a human body. A system is provided to deliver percutaneous electrical stimulation through at least one electrode to neurological motor points of the posterior and middle deltoid muscles to mediate such pain. One-time, continued and / or periodic dosing of treatment methods according to the present invention may result in a change to central nervous system maladaptive neuroplasticity.

A shoulder model and methods of shoulder arthroscopy using the shoulder model. The shoulder model includes an acromioclavicular (AC) joint assembly, a joint capsule assembly, a scapula mount, a shoulder musculature, a skin, and a base. The AC joint assembly is mounted on the scapula mount and the joint assembly is attached to the AC joint assembly and fastened using a screw / nut to form the shoulder assembly. The shoulder assembly is placed in the shoulder musculature and the skin is rolled over the shoulder musculature and zipped in place. The bones of the shoulder assembly are made of foam-cortical shell, the shoulder musculature is made of foam, the soft tissue components are made of thermoplastic elastomers, and the skin is made of vinyl. A method of practicing shoulder arthroscopy using the shoulder model includes mounting the shoulder model in a beach chair position, making anatomical references, establishing a posterior viewing portal, inserting cannulas into the glenohumeral joint or the subacromial space, creating a labral disruption or a rotator cuff tear, and repairing the rotator cuff tear or labral disruption.

A medical procedure for use in connection with a patient suffering from cuff tear arthropathy is disclosed. The medial procedure includes providing a humeral prosthesis having a prosthetic head component, wherein (i) the prosthetic head component includes a glenoid-bearing portion and an acromion-bearing portion, and (ii) the glenoid-bearing portion and the acromion-bearing portion define an outer bearing surface, and (iii) the outer bearing surface extends in a medial / lateral direction across a radial distance D, and (iii) D≧190°. The medical procedure further includes implanting the humeral prosthesis in the patient so that the acromion-bearing portion contacts and bears directly against a natural acromion of the patient during abduction of an arm of the patient that possesses the humerus.

A shoulder implant device includes one or more fixation features including an acromial intrusion element and an inflatable humeral balloon portion that receives a fluid through the acromial intrusion element. The intrusion element comprises a valve that can receive multiple needle sticks to add or remove fluid to or from the inflatable humeral balloon. The device is implanted in a subacromial space such that the one or more fixation features at least secure the device to the acromion and the inflatable balloon portion rests against the proximal end of the corresponding humerus. Fluid in the balloon portion maintains separation of the acromion and the humerus to reduce or prevent impingement.

The present invention provides an acromioclavicular joint and claricle fixer. Its technical problem is to make fixation reliable and simplity operation, and the technical scheme for solving the above-mentioned technical ploblem is characterized by that one end of said fixer is surrounding section, middle is main body section and another end is fork section, between the surrounding section, main body section and fork section at least two tunning places, said fork section processes an opened fork groove, the fork can be inserted under the posterior part of acromion, and the main body section isabutted on the external surface of clavicle, between of clavicle and acromion and lower surface of acromion, and the surrounding arm is placed on front side and back side of clavicle. Said invention is applicable to internal fixation of dislocation of acromioclavicular joint or clavicular fracture.

The invention provides a fixable inflatable saccule, which comprises a saccule body (1); a cavity is formed in the saccule body (1); an inflatable space is formed in the inner space of the cavity; theinflatable space is communicated to the outer space of the saccule body (1) through an inflatable structure (4); the size of the inflatable space can be adjusted; the saccule body (1) is provided with a wiring part (2), and the wiring part (2) is positioned on the end face of the saccule body (1) along the thickness extension direction and / or the radial end face of the saccule body (1); the wiring part (2) is fixedly connected with the capsule body (1) or integrally formed; the wiring part (2) is provided with stitch (3), and one or more stitches (3) are arranged on the wiring part (2) in a penetrating or fixing way. According to the fixable inflatable saccule, the saccule and the surrounding tissue can be fixed before or after inflation after being placed in the lower gap of the acromion, thereby avoiding displacement of the saccule in the movement process of the shoulder joint.

The method for engaging a person's sensorimotor complex includes providing a pair of lightweight sticks of equal length and weight; measuring a shoulder width from a first shoulder blade acromion of the person to a second shoulder blade acromion of the person; selecting from the plurality of devices a first lightweight stick and a second lightweight stick each having a length approximately equal to the width from the first shoulder blade acromion of the person to the second shoulder blade acromion of the person; grasping the first and second lightweight sticks with a respective first and second hands at a grasping position along the stick that is one shoulder width from a distal end of the stick; swinging the first and second hands back and forth between a first position and a second position; and walking while swinging the first and second hands back and forth.

The invention relates to an elastic system for an acromioclavicular joint, and belongs to the technical field of implantation material in a human body. The elastic system for the acromioclavicular joint is composed of a main plate, an upper assistant plate, a lower assistant plate, an elastic deformation structure and an elastic buffer structure. The main plate and the upper assistant plate are connected and fixed through the two ends of the elastic deformation structure. The main plate and the lower assistant plate are connected and fixed through a connecting support plate and the elastic buffer structure. Fixing holes are formed in the main plate and the upper assistant plate. According to the elastic system for the acromioclavicular joint, elastic fixing of the acromioclavicular joint is achieved through the elastic structure, the main plate, the upper assistant plate and the lower assistant plate, the acromioclavicular joint can recover to an original dissection corresponding relationship, fixing is firm and reliable, installation and positioning are simple, convenient and accurate, postoperative restoration loss does not occur, and the therapeutic effect is good. The elastic system for the acromioclavicular joint solves the problems that an existing hook steel plate structure appears unhooking after the operation, unsatisfied operational restoration and the postoperative restoration loss are prone to occur, and fixing of the acromioclavicular joint fixing plate on an acromion is not firm which influence the therapeutic effect seriously.
