This procedure was duly studied and verified its favorable results in multiple cases of patients, the > which merited-the implantation or inclusion of my Prosthesis for 311 total rehabilitation, since my prostheses as their own characteristics can exercise diverse functions according to the needs of each patient in order to recover the normal functionality of the affected man. The glenohumeral joint is by far the most frequently dislocated. Patients with IMD (ultidi- rectional instability) are distributed in a wide spectrum ranging from the individual with excessive ligamentous laxity, until they perform activities with extreme mobility in a repetitive way, passing through the person without greater laxity who suffers violent trauma. over the shoulder. The first structure of clinical interest, due to its special vulnerability to alterations in biomechanics, was the glenohumeral joint. The glenohumeral joint is a limited arti culation, which maintains a siitil balance between mobility and stability. To allow maximum rotations and avoid excessive translations of the humeral head in the glenoid, multiple static and dynamic factors intervene. Biomechanical studies have shown that the release affects the stabilizing mechanisms of the shoulder (glenohumeral contact surface, static stabilizers, capsule and impeller, dynamic stabilizers, rotator cuff and scapular rotators) at high tension. Despite the poor stability inherent in the glenohumeral joint, the ci; The nematic of the shoulder is maintained with a translation of few my lenses in any plane during the movement. The forces applied to the shoulder have magnitude and direction, so they can be subjected to vector analysis. The analysis of the resultant force reveals how the glenohumeral joint distributes the cage on its anatomical structure to create a stable situation within stable physiological ranges. The glenohumeral contact area (humeral-glenoid articular cartilage) plays two important functions: 1.-Distributes the load over a wide area, thus decreasing the tension in the contact surfaces. 2.- Allows movement of the opulent joint surfaces, with minimal friction and wear. The glenoid may be the only structure necessary to resist a direct force. Unfortunately, its dimensions will mitigate this capacity. It is an ellipse measuring 25 by 15 mm., - with a smaller radius of curvature than that of the head of the hummer, however, the glenoid impeller produces an increase in the ture curve, obtaining that the complex glenoidearodete / - capsule is concentric with the head, humeral. The. efficiency of this mechanism seems to be approximately - i of the 40? S that is, if the force, of compression in a glenoid - normal is 100 units, this mechanism can withstand a - translatory force of 40 a dades. Curiosamante if the labrum (Fig. 1 # 2) gleno deo is resected, this efficiency is reduced to half. This de-nuectra the extreme oepsibili a.? of the mechanism of concavity (ecp-pressure in the effective depth? e lu, glenoid fossa.) The aberrations of the normal pattern of the c rg-articular secondary to a stability ¿Lenohumeral anterior, -deteriorate the articular cartilage, being able to lucar a - ostecartritis («-is ^ e of the bone.) Through its intrinsic muscular mechanisms the scapula-works coiro both base eetable and mobile of the upper extremity (Eig. 2 # 5), also participates in all the movements of the body. It is evident that the pathologies that affect the stability and the ordered movements of the scapula will also affect the movements of the arm.The study of í'oppen and Walker revealed later that in normal subjects, the centers of moment of rotation are very close to each other and the center of the humeral head; however, there are some variations. The center of average-normal moment is 64 - 1.8 mm. A value located 10 mm or more from the center of the humeral head is considered abnormal.

In normal subjects, from 0 degrees to 30, and often from 0 to 60 degrees, the humeral head moves upwards on the surface of the glenoid fossa about 3 mm.

Beyond 60 degrees the position is more or less constant moving 1 to 2 mm up or down between subsequent-positions. The average margin from one position to another is 1.09 + - 0.47 iap of movement from bottom to top. It is interesting to note that in abnormal shoulders (such as those with a previous glenohumeral dislocation, tears of the rotator cuff and other causes that produce pain in the shoulder) - there is an increase of. center of moment, and of the excursion margin of the humeral ball. Poppen and Wallrer concluded that if a patient has a center of more than 10 mm. and a ball excursion of more than 1.5 mm *, the mechanics of the shoulder is abnormal due to some existing pathological state. On the other hand it is very important to point out that there are several failure mechanisms of the glenoid Labrum (? G.l # 2). Glenohumeral instability leads to wear forces that induce tearing of the Labrum and the capsule. * It is believed that the recurrent instability is the result of the loss of these stabilizing factors. the distension forces can also produce labral tears. According to the humeral head, it can be moved to any side, anterior, posterior, inferior or superior, causing a lesion of the labrum and ligaments. Can a combination of Andean translation patterns appear in Aegi? worsen labrum tears and capsular ligaments. Abnormal patterns of translation can affect both the interior and exterior structures of the rotator cuff. It is useful to define the instability of the Shoulder, as a clinical condition in which, an inadequate translation, of the humerus head in the glenoid compromises the comfort and the function of the ism. Multidirectional instability (IMD) is defined as the instability that occurs in more than one plane of movement in any direction. Conceptually separating true unidirectional instability from IMD is likely simplistic, since there is a sontinuum between these two entities. At. most of the anterior and posterior dislocations of the shoulder, if not all, are associated with something of inferior laxity or laxity in the opposite direction. Of all the bony elements that make up the scapular waist, the scapula is the most ingeniously constructed (Fig. 2- # 5) "Essentially, the scapula is a free floating bone structure, except for its inserts with the coraco ligament. clavicular and its acromioclavicular joint. Atín in these-points has a relatively free margin of movement. All of the foregoing in Theory, Practice, Illustrators, make up my novel and exclusive invention, truly effective for the treatment in patients with this type of Recurrent shoulder dislocation. , Surgical procedure only in our country.
