Aging is not a phenomenon exclusive to modern societies, it has been present in all stages of social development and has always been of interest to philosophy, art and medicine. However, during the past century, we are witnessing a unique situation: more and more people have passed the beginning of what man has called the stage of old age and the privilege of some has been transformed into an opportunity for many; This made the aging population a challenge for modern societies. It would suffice to point out that from the beginning of human history until the beginning of the 20th century, human beings achieved an average lifespan of 47 years and from then until today this average increased by almost 30 years and is considered one of the achievements. most important of humanity.

Introduction: In orthopedics, the use of rich plasma is still controversial, there is no consensus regarding its indications, and use, although its therapeutic usefulness for various conditions is proven, much remains to be studied on this promising topic. Purpose: With our study we intend to assess the clinical effectiveness and efficacy of the treatment imposed according to study groups. Method. A prospective pre-experimental study was carried out in adults with a diagnosis of orthopedic foot injuries, treated at the Orthopedics and Traumatology Service of the General University Hospital "Mártires del 9 de Abril", from January 2018 to December 2022, where the utility of the PRP is used and valued. Results Orthopedic foot injuries are more common in women between 41 and 60 years of age, 15.9% of the sample was treated with infiltration of platelet-rich plasma, pain decreased in all study groups, without However, the group where PRP infiltration is used represents the one with the best evolution of the patients seen in the clinic. Conclusions The results obtained in this study show that the treatment protocol applied is positive in each of the therapeutic options used from the point of view of pain improvement according to the visual analogue scale, highlighting the option of using PRP.

A prospective longitudinal study of 157 patients between the ages of five and 16 years, high-performance athletes, who were treated with epiphyseal and / or apophyseal injuries due to chronic stress in our service, was carried out in the period between January 1, 2000 and December 31, 2020, at the Mártires del 9 de Abril University Hospital in Sagua La Grande, Villa Clara province, Cuba. Of these patients, 102 are male, the most frequent ages of the affected children are between 13 and 14 years, pain and poor sports performance were the predominant symptoms, 67.7% (n = 106) were in radiological stage II and 70.9% (n = 7) in pathological anatomical stage II, which is closely related, but not the clinical stages.

The muscle skeletal system commonly suffers traumatic injuries, the tibia due to its anatomical characteristics is more susceptible to fractures. It is intended to present a series of preliminary results on minimally invasive osteosynthesis for the treatment of these lesions. Theoretical and empirical methods are used to perform the analysis of updated knowledge about them. Most of the patients treated with minimally invasive surgery for their tibia fractures are male (85.52%) and their age is generally between 40 and 60 years (48.15%). The most affected anatomical region was the distal third of the tibia. The surgical time for osteosynthesis decreased to 43 minutes, with few complications. It is concluded that MIPO is an option for the treatment of tibial fractures taking into account its indications, it can be reproducible without the need for special instrumentation and as it is a biological osteosynthesis that preserves vascularization and the fracture hematoma has fewer risks of complications.

Introduction: congenital radioulnar synostosis is an uncommon congenital anomaly, thatcauses a limitation of the forearm supination, often bilateral. The origin of this anomaly occurs when the differentiation of the cartilaginous contour of the radius and ulna does not take place during the embryonic period. Objective:to show two congenital radioulnar sinostosis cases analyzing variable about the topic. Case report:there are two different types of synostosis. In these cases the symptoms are mild because the compensate thein limitation in pronosupinationwith hypermobility of other joints of the upper limb. X-rays of upper limbs are the diagnostic procedures. The management will be conservative, but the treatment depends on the degree of functionality of the forearm. Conclusions:proximal radioulnarsynostosis is anon frequent affection, that brings about difficulties carrying out  actions with the hands, Its diagnosis is relatively simple by means of the clinical findings andplain X-rays of  the elbow.
