Youth soccer players: patterns of injury involving the primary growth plates of epiphyses.

Youth soccer (football) is immensely popular internationally. Earlier participation, sport sub-specialization, and year-around practice have led to an increased incidence of injury from both acute trauma and repetitive overuse. The growth plates (physes) of the immature skeleton are particularly vulnerable to injury and delayed diagnosis can lead to future growth disturbance and long-term morbidity. Familiarity with the various components of the growth plate complex necessary for ensuring normal endochondral ossification is fundamental in understanding the various patterns of imaging findings following injury. This review discusses the zonal columnar arrangement of the growth plate proper and the contrasting function of the vasculature within the subjacent epiphysis and metaphysis. This is followed by an evidence-based discussion of the common patterns of injury involving the epiphyseal primary growth plate observed among youth soccer players: subcategorized into physeal fractures (direct injury) and physeal stress injuries (indirect insult to subjacent metaphysis). In this section, the role of imaging and characteristic imaging features will be discussed. While the normal physiologic and pathophysiologic mechanisms can be applied to other growth plates, such as primary growth plates underlying the apophyses and secondary growth plates surrounding the secondary ossificiation centers, which also undergo endochondral ossification, the current review is focused on injuries involving the primary growth plates underlying epiphyses.

Terminology of the growing bone: A historical study.

Division of the growing long bone into individual basic parts, that is, diaphysis, metaphysis, physes and epiphyses, has become generally accepted and used. However, the origin of these terms is almost unknown. Therefore, we have analyzed the literature in order to identify their sources. The terms epiphysis and apophysis have been used since the time of Hippokrates, although with different meanings. During the time of Galen, the term apophysis was used to describe all types of bone processes, and epiphyses denoted articular ends. The term diaphysis denoting the middle cylindrical part of the long bone was used for the first time by Heister in 1717. The first to use the term metaphysis was Theodor Kocher in his books on gunshot wounds and on bone inflammation of 1895. On the basis of Kocher's study, Lexer published a radiological study of the vascular supply to bones in which he defined metaphyseal blood vessels as a separate group supplying a particular part of the long bone. The epiphyseal growth plate had no particular name from the time of its first description in 1836. During the second half of 19th century, this structure acquired different names. The term "physis" was therefore introduced in 1964 by the American radiologist Rubin in order to label the growth structure between metaphysis and epiphysis clearly. One year later, the term physis also appeared in the radiological literature, and during the following decades it spread in the orthopedic literature.

Detection of early metaphyseal changes in a piglet model of Legg-Calvé-Perthes disease using quantitative mapping of MRI relaxation times.

Legg-Calvé-Perthes disease (LCPD) is a childhood hip disorder characterized by ischemic injury to the epiphysis of the femoral head, but changes to the metaphysis have also been implicated in its pathogenesis. Quantitative magnetic resonance imaging (MRI) relaxation time mapping techniques are potentially useful to detect injury in LCPD, but studies to date have focused on the epiphysis. The purpose of this study was to assess whether T2, T1ρ, adiabatic T1ρ, and adiabatic T2ρ relaxation times can detect early metaphyseal changes in an LCPD piglet model. Complete epiphyseal ischemia of one femoral head was surgically induced and confirmed using contrast-enhanced MRI in n = 10 6-week-old piglets; the contralateral side was unoperated. The bilateral hips were imaged 1 week after surgery in vivo at 3T MRI using relaxation time mapping and contrast-enhanced MRI. Relaxation times and thicknesses of the metaphyseal primary and secondary spongiosa were measured and compared between the ischemic and contralateral-control femoral heads using paired t-tests. In the ischemic femoral heads, T2 relaxation times were significantly increased in the primary spongiosa (6.7 ± 9.8 ms, p = 0.029), and T2, T1ρ, adiabatic T1ρ, and adiabatic T2ρ relaxation times were significantly decreased in the secondary spongiosa (respectively: -13.3 ± 9.3 ms, p = 0.013; -32 ± 23 ms, p < 0.001; -43 ± 41 ms, p = 0.009; and -39 ± 13 ms, p < 0.001). The secondary spongiosa thickness was also significantly decreased in the ischemic femoral heads (p < 0.001). In conclusion, T2, T1ρ, adiabatic T1ρ, and adiabatic T2ρ relaxation time mapping techniques can detect early changes in the metaphysis following ischemic injury to the epiphysis of the femoral head in a piglet model of LCPD.

Conservative Rehabilitation Program for Osteochondroma of the Scapula: A Case Report.

One of the most frequent cartilage-capped outgrowths that develop beneath the periosteum due to cartilage ossification is osteochondroma. The second decade of life is noted as the most prevalent age of presentation. This case report looks at an uncommon osteochondroma presentation in a 20-year-old female with swelling along the right inferomedial border of the scapula. The patient presented with complaints of difficulty in daily activities and exhibited altered posture, decreased range of motion (ROM), muscle weakness, and altered shoulder function. The clinical assessment highlighted restricted shoulder and cervical ROM and muscle weakness in the trapezius, rhomboids, serratus anterior, and other surrounding muscles. Magnetic resonance imaging revealed an inferomedial bony outgrowth indicative of osteochondroma. A comprehensive physiotherapy intervention protocol for eight weeks was designed to alleviate pain, improve mobility, restore ROM, strengthen weakened muscles, correct posture, and enhance functions that were restricted. The protocol encompassed various techniques, such as muscle energy techniques (MET), proprioceptive neuromuscular facilitation (PNF), cold therapy, stretching, scapular mobilization, resistance exercises with TheraBand, postural correction exercises, ergonomic adjustments, scapular stabilization exercises, and 'J'-taping to aid in muscle activation and address rounded shoulder posture. Outcome measures for cervical and shoulder ROM and strength were measured to note the progression after rehabilitation. The case report emphasizes the importance of a tailored physiotherapy rehabilitation protocol in managing osteochondroma-related symptoms, showing the potential benefits of multifaceted interventions in alleviating pain, improving function, and boosting the quality of life for individuals with similar presentations.

Epifisiólisis femoral proximal, una entidad desapercibida en atención primaria / Proximal Femoral Epiphysiolysis, an Unnoticed Entity in the Primary Care / Epifisiólise próxima! do fémur: uma entidade desapercebida em atenção primária

Resumen: La epifisiólisis femoral proximal o deslizamiento capital femoral es un trastorno de la cadera que se caracteriza por un desplazamiento de la epífisis sobre la metáfisis a través de la fisis (cartílago de crecimiento), quedando la epífisis posterior e inferior. Es una entidad relativamente frecuente en atención primaria y prehospitalaria que genera dolor y limitación de cadera; sin embargo, por su sintomatología vaga es usualmente infradiagnosticada o es diagnosticada tardíamente generando consecuencias a largo plazo. Si se tienen en cuenta los factores de riesgo asociados a una adecuada exploración física y el uso imágenes diagnósticas se lograría hacer un diagnóstico oportuno y una disminución de la tasa de complicaciones.

Abstract: Proximal femoral epiphysiolysis or slipped capital femoral is a hip disorder characterized by a displacement of the epiphysis over the metaphysis through the physis (growth plate), leaving the epiphysis in a posterior and inferior position. It is a relatively frequent entity in primary and prehospital care that generates hip pain and limitation. However, due to its vague symptoms, it is usually underdiagnosed or diagnosed late, generating long-term consequences. If the risk factors associated to an adequate physical examination and the use of diagnostic images are taken into account, a timely diagnosis and a reduction in the rate of complications would be achieved.
