Abstract Background: Several studies have reported injuries and physical characteristics in adult elite weightlifters. However, few studies have evaluated such issues in adolescent amateur weightlifters. The purpose of this study was (1) to show the results of orthopaedic medical examinations in adolescent amateur weightlifters and (2) to evaluate the sexual differences in the obtained findings. Methods: The orthopaedic medical examinations had been performed cross-sectionally from 2012 to 2019, and the findings in young weightlifters were retrospectively evaluated. The orthopaedic medical examination included six assessments (physical examinations, generalized joint laxity, muscle and joint tightness, static alignment, muscle volume of the lower extremities, and medial longitudinal arch of the foot). A questionnaire survey regarding pain in the spine and lower extremities was also performed. Results: A total of 99 adolescent weightlifters were included (71 males and 28 females; mean age, 16.2 ± 0.2 years). A total of 9.1% of adolescent amateur weightlifters had received orthopaedic treatments, with spine injuries the most prevalent. Of the adolescent weightlifters who had not received orthopaedic treatments, 31.1% had pain in the spine or lower extremities (for > 4 weeks), accompanied with positive findings on physical examinations. There were no significant sexual differences in the incidence of pain or positive findings of physical examinations. Female weightlifters had a more reduced dorsiflexion of the ankle joint than male weightlifters (9.4 ± 1.9° vs. 14.7 ± 1.1°, p = 0.02). Male weightlifters had a significantly lower flexibility of the quadriceps than female weightlifters.Conclusions: More than one-third of adolescent competitive weightlifters had pain or positive findings of physical examinations in the spine or lower extremities. The results of orthopaedic medical examinations in this study may help clinicians and young weightlifters to prevent injuries in competitive weightlifting.

ObjectivesMedical examinations for adult elite athletes are performed all over the world, however, no studies in the relevant English literature have reported on orthopaedic medical examinations for young amateur athletes. The purpose of this study was to report the results of orthopaedic medical examinations of the spine and lower extremities in young amateur athletes.MethodsThis repeated cross-sectional study from 2014 to 2018 included a total of 323 young amateur athletes (age, 12–18 years) who were active in one of the following four sports: boxing, canoeing, weightlifting and track and field. The orthopaedic medical examination consisted of six assessments (physical examinations, the generalised joint laxity, muscle and joint tightness, static alignment and muscle volume of the lower extremities and the medial longitudinal arch of the foot). Questions regarding pain in the spine and lower extremities were also performed.ResultsAmong 323 young amateur athletes, 17 (5.3%) had received orthopaedic treatment at the time of the medical examination, with spondylolysis being the most common cause (29.4%, 5/17). Among 306 young athletes who had not received orthopaedic treatment, 61 (19.9%) had at least one positive finding in physical examinations or had pain in the spine or lower extremities. Anterior drawer test of the ankle and Kemp test for the spine accounted for 34% and 28% of positive findings, respectively. Low back pain and knee pain accounted for 58% and 16% of pain, respectively.ConclusionsThe present study showed that approximately one-fifth of young amateur athletes who had not received orthopaedic treatment had pain in the spine and lower extremities and positive findings in physical examinations that may require orthopaedic treatments. In addition to the early detection of injuries, orthopaedic medical examinations for young amateur athletes provide an opportunity to educate such athletes.

Injury Mechanisms

A recent survey of epidemiological studies lists ankle injuries as one common sport injury. However, the details of the injury mechanisms of ankle sprains — the majority of ankle injuries — remain not well understood. The purpose of the presented study is twofold. The first aim is to introduce a new, widely applicable method to calculate ankle joint torques during movement using inverse dynamics. The subtalar and talocrural joint are modeled as anatomically based revolute joints. The kinematics of the lower extremities and ground reaction force are used as input data. Second, a comparison of two calculation approaches (dynamic versus static) is reported, aimed at verifying and simplifying the introduced method to have a more convenient tool at hand for applications in the field. For one first movement measurement (hopping), the calculated joint torques show a good match for the two calculation approaches. After further application, the evaluation of the resulting joint torques will provide further insights into the joint mechanics and can contribute to a better understanding of the respective injury mechanisms. Hence, this approach is interesting for researchers to be used in order to understand ankle injuries and to determine the influence of landing grounds and shoes on ankle joint torques.

The article analyzes the up-to-date state and problematic issues of forensic medical diagnosis of cervical spine injuries. It establishes that there are cases when forensic medical experts underestimate the outcomes and consequences of this trauma. It studies the state of the central hemodynamics of the injured with cervical spine traumas. At the same time 107 injured were divided into two groups: with clear and moderate manifestations. The research applied an objective and modern method of Doppler echocardiography. The conducted research has demonstrated significant changes in extraand intracerebral blood flow. The results of the comparative analysis show that forensic medical assessment of cervical spine traumas should take into account the results of Doppler echocardiography. Among these results the most informative are functional changes of the cerebral and spinal arteries. The manifestation of these deviations is determined, primarily, by the severity and time of injuries. The article determines the ways of improving forensic medical examinations of the injured with cervical spine traumas. It demonstrates the criteria significance of changes in bloodflow of cerebral and cervical arteries of the injured while establishing the severity of injuries.

The study of human gait is of interest in determining its individual characteristics that affect the loads experienced by the joints of the lower extremities. To analyze the gait in the lateral projection, an experiment was carried out with placed markers on the subject's body to determine the interarticular angles in the hip, knee and ankle joints. The graphs of the dependences of these angles on time were built, corresponding to a certain phase of the step. It was found that the range of changes in the angle in the left ankle joint in the subject was significantly different from the dependence obtained for the right joint. Based on the subject's anamnesis, we associate these differences with the fact that there was an ankle joint injury that affected the condition of the ligamentous apparatus of the joint. In further work, it is proposed to consider a person's gait not only in the lateral, but also in the frontal (anteroposterior) plane to assess all movements in the joints, especially those associated with the abduction of the limbs and the human body from the vertical line on the specified plane.

The purposes of the project were to monitor the development of the lower extremities and the longitudinal arch of the foot and to determine whether or not arch support footwear (three types) affected development of a neutral arch in toddlers 11 to 14 months of age until age 5 years. A total of 125 beginner walkers were recruited through the pediatrics department during a period of 1 ½ years and divided by lot into four different footwear groups (one nonarch supportive). The group was studied for 4 years by physical examinations, x-ray films, and pedotopography (a Moire fringe technique of photography). At initial examination all of the apparently normal toddlers had pes planus by all clinical, roentgenographic, and photographic measurements. There were no cavus feet at that time or at 5 years of age. Arches developed regardless of the footwear worn but development was faster during the first 2 years (until age 3 years) with arch support footwear. The rapidity of arch development until 5 years of age continued in those children who wore longitudinal arch cookies. Ossification of the sustentaculum tali begins at approximately 5 years of age but is not complete for at least another 1 to 2 years. Hyperpronation was present in 77.9% and genu valgum in 92.3% of the 5-year-old children. These conditions are apparently the norm at this age in both boys and girls.

Summary: Currently existing "Rules for determining the severity of bodily injuries" do not correspond to the modern classification, the level of knowledge about clinical course and outcomes of open fractures of the lower extremities. Purpose - to conduct a comparative retrospective analysis of forensic medical examinations results to determine the severity of bodily injuries in victims with open and closed fractures of the lower extremities. Material and methods. Research material - 425 acts (170 primary, 185 commissions, 70 complex) forensic medical examinations of victims with fractures of the femur and / or tibia, performed in the Kharkiv Regional Bureau of Forensic Medicine for the period February - June 2018. Research methods - retrospective analysis, descriptive statistics. Results. It was found that both at the time of injury and in the event of its (injury) consequences in victims with a leading injury of the lower extremities, open fractures of the femur and tibia are assessed as severe bodily injuries without taking into account the nature of the fracture and the degree of damage to soft tissues (according to generally accepted classifications), although these data determine the features of treatment measures and the prognosis of trauma at the prehospital and hospital stages. Conclusions. Open fractures of long bones of the lower extremities of type I and II in clinical course, treatment approaches, a risk of complications differ significantly from open fractures of type III. Acute blood loss and hemorrhagic shock, which develop in fractures of long tubular bones as a result of damage of intraosseous, periosteal and muscle vessels, are characteristic of both open and closed fractures. The complicated consequences of open fractures of the lower extremities described in the literature are not life-threatening. The severe bodily injuries revealed as a result of this study were mainly the result of non-union periarticular and intra-articular fractures with persistent joint contracture. The above facts indicate the need to correct the "Rules for determining the severity of injuries" in the case of open fractures of long tubular bones and their differentiated use in fractures of varying complexity with varying degrees of soft tissue damage.

Background. Varicose disease is the most wide-spread vascular disease of the lower extremities. The form of occupation and work conditions significantly affect the cardiovascular system due to regular and unavoidable action of the human body. Aim: to determine the influence of hazardous work conditions on the incidence of varicose veins of the lower extremities among the persons subjected to periodic medical examinations; to identify the most important factors in the development of this pathology; to propose methods for preventing the occurrence of varicose veins in the manufacturing sector with hazardous conditions. Methods. Analysis of the outpatient histories (account form No. 025 \ у-04) of employees having periodic medical examinations was performed, with 528 female and 1489 male patients in total. The analysis of the outpatient histories, as well as processing of the obtained material were accomplished using the universal statistical package of Statgraphics Plus for Windows. Results. It has been established that hazardous work conditions, such as vibration, increase the incidence of varicose veins of the lower extremities, and the hazardous work experience plays the main role in increasing the incidence of this pathology. Conclusion. Hazardous work factors affect the incidence of the varicose disease of the lower extremities towards its elevation. The age, hazardous work experience and conditions associated with vibration play the major role in the increase of the disease incidence. A set of measures aimed at the prevention of varicose disease in the manufacturing sector has been suggested as a result of the study.

Background: The spring ligament complex (SLC) is a static support of the head of the talus and a major anatomical contributor to the integrity of the medial longitudinal arch, particularly if the dynamic support of the posterior tibial tendon is compromised. For this reason, we sought to further elucidate the anatomical components and dimensions of this ligamentous complex. Methods: Dissection was performed on 30 adult cadaver feet disarticulated at the ankle joint that were preserved by embalming technique. Results: The superomedial ligament (SML) averages 42.51 ± 3.93 mm and 33.44 ± 3.34 mm at the superomedial and inferolateral borders, respectively. The width at the level of sustentaculum tali and navicular tuberosity averaged 20.00 ± 2.35 mm and 10.26 ± 2.05 mm, respectively. The medioplantar oblique (MPO) ligament averaged 23.56 ± 2.15 mm and 21.20 ± 1.42 mm at the medial and the lateral borders, respectively. The widths at the navicular and calcaneal side were 2.71 ± 0.39 mm and 8.14 ± 0.56 mm, respectively. The inferoplantar longitudinal (IPL) ligament measured 4.26 ± 0.43 mm and 2.66 ± 0.42 mm at the medial and lateral borders, respectively. The width at the calcaneal and navicular insertions measured 5.21 ± 0.53 mm and 3.39 ± 0.39 mm, respectively. Conclusions: The distinction between the SML and MPO components of the spring ligament complex is difficult. This study tried to clarify the dimensions and configurations of these components of the SLC. Clinical relevance: This effort may aid surgeons who wish to repair this ligament with more precision.
