MORPHOLOGICAL AND BIOMECHANICAL CORRELATION IN THE TENNIS ELBOW

With the definition of 'Tennis Elbow' are rubricated a series of pathologies which recognize a common origin in a damage on a level of the myotendon jointing apparatus. A decodification in biochemical molecular key of the jointing apparatus consents to identify a series of microstructures which develop specific functions of a connection between the motory unity and the tendon system. These formations ty ambient such as the one assured by proteoglicanic matrix in which perform the nervous formations wich are appointed to the peripheric control of the rnyotendon jointing. The morphological research led on a level of the myotendon jointings in normal conditions and in the course of insertional pathologia, has displayed howat an insertional level, it takes place deep structural changes characterized by progressive loss of the visco-elasticity . These dates have been put in relation to study of the elbow and wrist joints, in normal conditions and in course of 'tennis elbow'. In particular it has been inquired, in isokinetic, the relation of force of / the 'motor muscles' which control the motory unities of the elbow and wrist joints. In has been observed significative alteration of case control in the peak torque ratio (%) of the an d flex muscles of the wrist (80 vs 40) in the relation of pronators/supinators (138 vs 88). The results of this study suggest how at the base of “tennis elbow' there are biological and biomechanical conditions which determine the arising of pathologia, they condition the evolution and constitute the potential 'target' of the therapy

INSERTIONAL TENDINOPATIES IN ATHLETES: CLMICAL BIOMECHANICS AND MORPHOLOGICAL CORRELATIONS

The aim of the study was to investigate the biomechanics aspects of some mecystatisis technics utilized to re-equilibrate the kinetics chains of the human body. The first part of the study foresaw a pilot trial through which the authors have observed the biomoleculars aspects induced by different allongement methods for biomechanics setting and extension time. For the pilot trial we have made use of 5 rabbits. A qualitative evaluation of the results brings to think how it realizes, in the treated limbs with muscular strain, an important increasing of the proteoglycanics rate. Following this first part, a clinical study, in which the biomechanical redress of muscular kinetics chain effectiveness induced by elongation technics, it has been investigated in 14 patients spiltted up in 2 groups, treated/controlled, affected by recto-adductive syndrome. The first group was submitted to a muscular redress by active elongation technics as a protocol foresaw 5 weakly sittings of 1 hour. For the spontaneous and active pain displacement (evaluated by MAIGNE method, 0-3 scale) this group have been treated for 28 days with an infiltration (750mcg of Somatostatin/Stilamin Serono) at adductor tendons level or to the abdominal rectoinsertion, every seven days. From the results we can pointed out an important decreasing of spontaneous and active pain of the treated group versus the controlled (
