RESUMEN
INTRODUCTION: Early diagnosis of joint damage is pivotal in haemophilia to prevent the occurrence and progression of haemophilic arthropathy thus providing optimal personalised management. The haemophilia joint health score version 2.1 (HJHS) is based on a physical examination of the mainly affected joints. Musculoskeletal ultrasound has demonstrated the capability to detect early changes in terms of synovitis and osteochondral damage. The haemophilia early detection with ultrasound (HEAD-US) score has been proposed as a simple and reliable evaluation tool. AIM: This study aims to investigate the correlation between the HJHS and the HEAD-US scores performed by two independent operators (physical therapist and musculoskeletal ultrasound expert) for the evaluation of the joint health status of patients with haemophilia. METHODS: Consecutive adult patients independent of the severity degree were included. Elbows, knees and ankles were evaluated by a physical therapist by HJHS and by a musculoskeletal ultrasound expert following the HEAD-US protocol. RESULTS: We observed a good positive correlation between HJHS and HEAD-US (Spearman's rho 0.72). The main discrepancy in conceptually similar domains was found between the HJHS swelling and the HEAD-US synovitis (rho 0.17), as ultrasound was able to detect even mild synovitis when HJHS swelling was scored 0 in up to 40% of cases. CONCLUSIONS: The HJHS and HEAD-US correlate well even when performed by two independent operators. Musculoskeletal ultrasound is particularly useful for the early detection of synovitis. The routine assessment of both scores helps clinicians define the stage and extension of joint involvement and set up a personalised treatment.

The pediatric elbow is a complex joint that undergoes rapid growth and development. The normal anatomy of the elbow varies depending on the age of the patient, which can be challenging for imaging interpretation. This article reviews developmental variants and common pathologies of the pediatric elbow, with a focus on their radiologic features. Normal anatomy and development of the pediatric elbow are discussed, including the six ossification centers and elbow alignment. Congenital anomalies such as longitudinal deficiencies of the upper extremity are reviewed. Some common injuries that affect the elbow, such as supracondylar fracture, lateral condyle fracture, medial epicondyle avulsion, and radial head dislocation are also described.

Knee pain is one of the most common indications for radiography in the evaluation of musculoskeletal disorders in children and adolescents. According to international guidelines, knee radiographs should be obtained when there is the suspicion of an effusion, limited motion, pain to palpation, inability to bear weight, mechanical symptoms (such as "locking"), and persistent knee pain after therapy. When indicated, radiographs can provide crucial information for the clinical decision-making process. Because of the developmental changes occurring in the knee during growth, the assessment of knee radiographs can be challenging in children and adolescents. Radiologists unfamiliar with the appearance of the knee on radiographs during skeletal maturation risk overcalling or overlooking bone lesions. Image acquisition techniques and parameters should be adapted to children. This article describes the most common challenges in distinguishing pathology from the normal appearance of knee radiographs in the pediatric population, offering some pearls and pitfalls that can be useful in clinical practice.

During normal development, imaging findings in the immature knee joint may mimic pathology or indicate transient sites of weakness, prone to injury. This article reviews the development of the knee joint, age- and maturation-dependent imaging considerations, and various developmental variants that can be encountered, subdivided into those that involve the tibiofemoral and patellofemoral compartments, soft tissues, and osseous components. The tibiofemoral compartment section reviews the focal periphyseal edema zone (FOPE), ossification variants of the femoral condyles, distal femoral metaphyseal cortical irregularity from periosteal traction, and the metaphyseal subperiosteal stripe, which should be distinguished from pathologic mimickers such as endochondral ossification dysfunction, osteochondritis dissecans (OCD), fibroosseous lesion, periosteal and subcortical pathologies. The patellofemoral compartment section includes a review of partite patella, dorsolateral defect, variant trochlear morphology, and maturation-dependent sites of transient weakness that are prone to injury from repetitive overuse (Sinding-Larsen-Johansson syndrome and Osgood-Schlatter disease) and avulsion fractures (patellar sleeve and tibial tubercle avulsions). Finally, soft tissue (discoid lateral meniscus, meniscal flounce, anterior cruciate ligament variants) and osseous components (meniscal ossicle, fabella, and cyamella) are reviewed.

The pediatric hip undergoes significant changes from infancy through adolescence. Proper maturation is crucial for the development of a stable and functional hip joint. Imaging interpretation of the pediatric hip requires distinguishing normal variants and maturation patterns from pathology. We review femoral ossification centers, variants, and conditions that affect the proximal femur, such as Legg-Calvé-Perthes disease; the acetabulum, such as developmental hip dysplasia; the acetabular labrum, such as femoroacetabular impingement; and synovial pathology in children through adolescence. Understanding the spectrum of hip conditions and using advanced imaging techniques are essential for the accurate diagnosis and effective management of pediatric hip disorders.

Intra-articular tumours are uncommonly encountered in routine practice and may present diagnostic challenges to pathologists. Challenges unique to this site include distinction from more common reactive synovial conditions, which are far more common; histologic variability; superimposed reactive changes; and often, lack of provided clinicoradiological context. This article reviews the pathology of the synovial tumours and tumour-like lesions, including diagnostic pearls, pitfalls and rare entities.

PURPOSE: To evaluate the distribution of intra- and extraarticular MRI findings in children and adolescents with clinically suspected intraarticular cause of hip pain in order to assess the need for additional intraarticular contrast administration. MATERIAL AND METHODS: Database was searched over a period of 34 months retrospectively for consecutive hip MR arthrography in young patients (8-17 years) with suspected intraarticular cause of hip or groin pain. Exclusion criteria were prior hip surgery, follow-up examination due to known intraarticular pathology, incomplete examination, qualitatively non-diagnostic examinations, and missing informed consent. Reports of fellowship-trained MSK radiologists were searched for intraarticular versus extraarticular findings explaining hip or groin pain. RESULTS: Seventy patients (68% female; median age: 14.5 years; range:10.8-16.9 years) were analyzed. No reason for pain was found in 30 (42.9%) hips, extraarticular reasons in 20 (28.6%) cases, intraarticular in 14 (20.0%), and both (intra- and extraarticular) in 6 (8.6%) hips. Most common extraarticular reasons were apophysitis (14.3%), other bony stress reactions (12.9%), intramuscular edema (7%), tendinitis (5.7%), and trochanteric bursitis (4.3%). Labral pathology was the most common intraarticular finding (overall:34.3%; partial tear:15.7%, complete tear:15.7%), most frequent at the anterosuperior position (81.8%). Cartilage defects (1.4%), intraarticular neoplasia (1.4%), and tear of the femoral head ligament (2.8%) were rarely found. Synovitis and loose bodies were not observed. Cam-(37.1%) and pincer-configurations (47.1%) were common while hip dysplasia was rare (5.7%). CONCLUSION: MRI in children and adolescents with hip pain should be done primarily without intraarticular contrast administration since most cases show an extraarticular pain reason or no diagnosis detectable with MRI.

The use of ultrasound by emergency physicians is now well established. It can be integrated as an extension of the clinical examination, providing diagnostic support during consultation in the emergency department. However, its use in osteoarticular pathologies remains less frequent, despite a growing body of literature demonstrating its value in a variety of pathologies. Ultrasound is operator-dependent, so its proper use requires dedicated training. In Switzerland, training opportunities in osteoarticular ultrasound are still poorly known and not widely used by emergency physicians. This article describes the possibilities of use in the case of osteoarticular pathologies frequently encountered in emergency departments.
L'utilisation de l'échographie par les urgentistes est actuellement bien établie. Elle peut être intégrée comme extension de l'examen clinique et apporte alors une aide au diagnostic lors d'une consultation dans le service des urgences. Son utilisation pour les pathologies ostéoarticulaires reste cependant moins fréquente, malgré une littérature croissante montrant son intérêt dans des pathologies variées. L'échographie est dépendante de l'opérateur et son utilisation adéquate nécessite une formation dédiée. Les possibilités de formation à l'échographie ostéoarticulaire en Suisse restent encore peu connues et peu suivies par les médecins urgentistes. Cet article décrit les possibilités d'utilisation pour des pathologies ostéoarticulaires fréquemment rencontrées aux urgences.

Medial coronoid disease (MCD) is a common disease often associated with thoracic limb lameness in medium- and large-breed dogs. The term MCD includes subchondral changes of the medial coronoid process (MCP), as well as pathologies of both cartilaginous surfaces. As there are only a few comprehensive and detailed studies on the trabecular structure of the medial coronoid, the goal of this study was to compare the trabecular structure of the ulnar trochlear notch of canine cadavers with and without MCD using different micro-computed tomographic (micro-CT) parameters. Fifty-eight elbow joints from 29 canine cadavers of MCD-predisposed and non-predisposed breeds (control group) were examined radiographically, macroscopically and by microcomputed tomography. The study included elbow joints of eight Labrador Retrievers (21.6-37 kg), seven Golden Retrievers (26.3-42 kg), seven Bernese Mountain dogs (31-47 kg) and seven dogs of non-predisposed breeds (19.7-52 kg) (control group). The final diagnosis of MCD was based on necropsy and micro-computed tomographic examinations. Micro-CT examinations were performed using XtremeCT II (Scanco Medical, Zurich, Switzerland) and the following parameters were examined: bone volume fraction (BV/TV), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), trabecular number (Tb.N), connectivity density (Conn.D) and degree of anisotropy (DA). Twenty-four elbows of 44 elbows of the predisposed breeds (Labrador Retrievers, Golden Retrievers Bernese Mountain dogs) showed subchondral changes and lesions of the cartilage surfaces. The result of this study is a higher density (BV/TV) of the trabecular bone of the ulnar trochlear notch in elbows affected by MCD compared to the control group. The increased density due to trabecular reconstruction in the ulnar trochlear notch is likely the result of selectively increased loading during life.

BACKGROUND: Primary hyperoxaluria consists of a group of inherited disorders with enzymatic defects in the glyoxylate pathway, leading to decreased oxalate metabolism. The resulting oxalic deposition is specifically responsible for kidney disease and joint disease. Neonatal oxalosis is the most severe form of primary hyperoxia type 1, with the onset of end-stage renal disease in childhood. CASE PRESENTATION: A 55-year-old hemodialysis man was referred to Nephrology because of inflammatory polyarthralgia and periarticular swelling evolving for six months. He had been on hemodialysis for six years for end-stage chronic renal failure, diagnosed at the same time as primary hyperoxaluria. Radiological investigation showed a rugby jersey appearance on the lumbar spine, budding calcium tone opacities next to large joints and clavicles, vascular calcifications and tumoral calcinosis. The synovial fluid contained a few cells with polymorphic intracellular crystals. We ruled out hyperparathyroidism, hypoparathyroidism, and related phosphocalcic disorders, and we retained arthropathy and tumoral calcinosis secondary to primary hyperoxaliuria. The patient also had congestive heart failure. Despite intensification of hemodialysis, he did not improve and died at the age of 56 in the context of cachexia. CONCLUSION: This rare case documents the possible occurrence of late clinical presentation and long survival in primary oxalosis with extra renal complications.

OBJECTIVE: To describe the prevalence of elbow dysplasia (ED) in 13 dog breeds in France. ANIMALS: A total of 18,870 elbow radiographs taken from 2002 to 2022 were evaluated by 2 independent examiners. METHODS: For each breed, the incidence of each of the 4 International Elbow Working Group scoring classes was extracted from the database. Breeds were excluded if fewer than 150 radiographs had been read for that breed. RESULTS: This study included 17,861 records for 13 dog breeds: American Akita, Alaskan Malamute, Old German Shepherd (Altdeutscher Schäferhund), American Staffordshire Terrier, Australian Shepherd, Belgian Shepherd, White Swiss Shepherd, Bernese Mountain Dog, Cane Corso, Czechoslovakian Wolfdog, Rhodesian Ridgeback, Rottweiler, and Dogue de Bordeaux. The overall prevalence of ED was 11.4%, ranging from 1.1% in the Czechoslovakian Wolfdog to 32.2% in the Dogue de Bordeaux. The Dogue de Bordeaux, Rottweiler, Bernese Mountain Dog, and Cane Corso breeds were most commonly affected by ED. The prevalence of ED was significantly higher in male dogs than in female dogs (17.5% vs 10.5%, P < .05). Joint incongruity and fragmented coronoid process were the 2 most common primary ED lesions identified. The prevalence of ED among the dogs evaluated decreased over the timeframe of the study. CLINICAL RELEVANCE: The results of this study help to clarify the prevalence of ED in different breeds in France. These data should be interpreted with caution as this study included a small percentage of the total number of dogs born for each breed in France over the study period.

Sacroiliac dysfunction (SID) is a condition seen in horses associated with poor performance that affects hind limb gait and impulsion. The condition comprises pain and dysfunction but there lacks clarity around the aetiopathogenesis and whether SID encompasses abnormal joint pathology, abnormal joint movement, abnormal regional biomechanical function, joint laxity and pain, or various combinations of these that may vary over time. Clinical assessment remains challenging for equine clinicians due to the deep location of the sacroiliac joint (SIJ) and surrounding structures which limits access for palpation, diagnostic imaging and joint-specific injection. There is no recognised single reference standard diagnostic test for SID. Clinical diagnosis has been based on ruling out other causes of hind limb lameness, along with combinations of ultrasonography, scintigraphy and periarticular anaesthesia of the SIJ. Recent studies have highlighted the lack of specificity of injections targeting the SIJ, with significant dispersal of injectate into surrounding structures including around the lumbosacral joint (LSJ). Advanced imaging modalities such as computed tomography offers promise for assessment of the structure and pathology of the SIJ and surrounding bony structures. However, there is a need to improve the understanding of the significance of anatomic variation of the sacroiliac region structures, with recent studies reporting detailed anatomic variation in groups of horses with and without SID. There are also limitations around functional assessment of the joint which is still largely reliant on a thorough clinical examination. This review aims to present an update on clinical approaches to the diagnosis of horses with SID, and to consider the challenges and limitations.

En los apicultores se ha descrito una artropatía inflamatoria de etiología desconocida pero relacionada con su actividad profesional. Se expone el caso de un apicultor que tras la picadura de abeja presentó una artritis de la articulación interfalángica del primer dedo de la mano izquierda. Aunque el curso clínico subagudo y los hallazgos de la RMN obligaban a plantear el diagnóstico diferencial con un proceso infeccioso, el resto de pruebas analíticas, de imagen y la evolución, junto al antecedente de episodio similar unos años antes en un dedo de otra mano tras la picadura de abeja, permitió el diagnóstico de esta entidad
An acute inflammatory arthritis of unknown cause has been described in beekeepers in relation to their work with the hives. We present the case of a beekeeper who, after a bee sting, developed arthritis of the interphalangeal joint of the first finger of his left hand. Although the subacute clinical course and the magnetic resonance imaging findings required the differential diagnosis with an infectious process, the rest of the laboratory tests. other imaging studies and the course, together with a history of a similar episode a few years earlier on a finger of the other hand after a bee sting, enabled us to diagnosis this condition

Introducción: La enfermedad de Still del adulto es una enfermedad reumática, inflamatoria, sistémica y crónica que generalmente comienza sobre los 40 años de edad, pero puede aparecer en edades más tempranas. Se caracteriza por gran variedad de manifestaciones generales, articulares, fiebre y rash principalmente. Etiopatogénicamente, el proceso inflamatorio crónico que se genera durante el curso de la enfermedad es el responsable de las manifestaciones clínicas y del daño articular que se produce. Objetivo: dar a conocer los elementos básicos para el diagnóstico de la enfermedad de Still del adulto. Caso clínico: se presenta el caso de un paciente masculino, de 21 años de edad, que acude a consulta con manifestaciones clínicas que permiten realizar el diagnóstico de una Enfermedad de Still del Adulto. Conclusiones: La enfermedad de Still del Adulto, a pesar de no tener un patrón de deformidades tan amplio como la artritis reumatoide, también produce daño articular que puede comprometer la función de la articulación afectada. Resulta importante identificar precozmente las manifestaciones clínicas que hacen sospechar su diagnóstico para minimizar, retrasar o prevenir la afectación de las articulaciones(AU)
Introduction: adult Still's disease is a rheumatic, inflammatory, systemic and chronic disease that usually begins around 40 years of age, but may appear at younger ages. It is characterized by a great variety of general, joint, fever and rash manifestations. Etiopathogenically, the chronic inflammatory process that is generated during the course of the disease is responsible for the clinical manifestations and joint damage that occurs. Objective: to present the basic elements for the diagnosis of adult Still's disease. Clinical case: the case of a male patient, 21 years of age, who comes to the clinic with clinical manifestations that allow the diagnosis of an Adult Still's Disease. Conclusions: adult Still's disease, despite not having a pattern of deformities as extensive as rheumatoid arthritis, also produces joint damage that can compromise the function of the affected joint. It is important to identify early clinical manifestations that make your diagnosis suspect to minimize, delay or prevent the involvement of the joints(AU)
