ABSTRACT
CASE: Bizarre parosteal osteocartilaginous proliferation (BPOP) is rare, especially in the foot. To the best of our knowledge, multifocal BPOP has yet to be reported. We are reporting a case of a 40-year-old woman who presented with 4 bumps over her midfoot and toes. After staging studies, we excised the lesions, and histopathology confirmed BPOP. No local recurrence was observed at the end of the 2-year follow-up. CONCLUSION: BPOP should be considered in the differential diagnosis of multiple foot bumps, whether synchronous or metachronous, which may present multifocally in the foot.

BACKGROUND: The purpose of this study was to evaluate the prevalence of foot involvement in psoriatic arthritis and to describe its different clinical and radiological features. PATIENTS AND METHODS: We conducted a cross sectional study including 40 patients with psoriatic arthritis over a period of 12 months. Anamnesis, clinical examination of feet, podoscopic examination, X-rays of feet and heels, and ultrasound in B mode and power Doppler mode were done for each patient. RESULTS: Foot involvement was found in 95% of cases. It was symptomatic in 70% and inaugural of the disease in 20% of cases. The hindfoot and the forefoot were the sites most affected (77.5% and 47.5% respectively). The involvement of the midfoot was rarer (25%). Dactylitis was found in 17.5% and deformities of forefoot were found in 22.5% of cases. Antalgic gait was noted in 17.5% and static disorders of foot at podoscopic examination were identified in 35% of cases. Feet dermatological manifestations were found in 45% of cases. Diagnosis of different rheumatological manifestations was based on clinical findings and caracteristic radiological images on X-rays. We demonstrate he sensitivity of ultrasound in the detection and the diagnosis of different foot lesions including enthesitis, synovitis and tenosynovitis, dactylitis, bone erosions and psoriatic nail dystrophy.

BACKGROUND: Lameness has been associated with compromised animal welfare and reduced productivity in dairy cattle herds worldwide. However, little is known about the prevalence of claw lesions in the dairy buffalo population in Egypt. Furthermore, the optimum measurements for claw trimming in buffalo are unknown. A cross-sectional cadaver study was conducted where 135 pair buffalo hind feet were collected from 4 slaughterhouses and examined for the presence of claw lesions. The proportion and associated 95% confidence interval (CI) of each type of lesion were calculated. A separate set of healthy claws (n = 26) underwent ultrasonography (US) and computed tomography (CT). The agreement between US and CT measurements was assessed using Passing-Bablok regression and intraclass correlation coefficient. The CT measurements were used to calculate trimming recommendations. RESULTS: At least one lesion was identified in 242 claws (89.6%, 95% CI = 85.4-93.0). In healthy claws, poor to moderate agreement was identified between US and CT measurements which could be due a sample size of the study. The average ± standard deviation (SD) minimum recommended external wall length of the lateral and medial claws in heifers was 7.1 ± 0.36 cm and 7.5 ± 0.35 cm, respectively. The average ± SD minimum recommended external wall length in buffaloes over five years of age was 8.2 ± 0.27 cm and 8.4 ± 0.39 cm for the lateral and medial claws, respectively. CONCLUSIONS: The study found a high prevalence of claw lesions in buffalo in Egypt, the clinical significance of which requires further elucidation. Recommended measurements will help guide claw trimming in buffalo to minimise lesions.

OBJECTIVE@#To analyze radiological characteristics of Muller-Weiss disease, evaluate the clinical value of the imaging examination in diagnosis of Muller-Weiss disease.@*METHODS@#The imaging data of 26 patients with Muller-Weiss disease were collected from September 2015 to August 2020, including 7 males and 19 females, aged 43 to 68 years old with an average of (52.7±4.6) years old. In the X-ray examination observed the shape and position of the navicular bone. The talar-first metatarsal angle(TFM) was measured on the weight-bearing anteroposterior radiograph. The arch angle and angle between mid-axis of talus and mid-axis of the first metatarsal(Meary angle) were measured on the weight-bearing lateral radiographs. The morphology, density, adjacent joint space and position of the navicular bone were evaluated by computed tomography(CT), and magnetic resonance imaging(MRI) was used to observe the shape, signal, cartilage and surrounding soft tissue changes of the navicular bone.@*RESULTS@#Among 26 patients, 21 cases were unilateral and 5 cases were bilateral;X-ray examination showed that the lateral part of navicular bone of foot was compressed and flattened, showing"comma like"or"drop like", navicular moved to the medial side, partial fragmentation of bone, peripheral articular hyperplasia, uneven density and narrowing of relationship gap. According to Meary angle and deformity degree of the affected foot on the lateral X-ray of the load-bearing foot, Maceira staging was performed. There were 0 cases in stageⅠ, 2 cases in stage Ⅱ, 11 cases in stage Ⅲ, 9 cases in stage Ⅳand 4 cases in stage Ⅴ. CT examination showed bone fragmentation, medial displacement of navicular bone and formation of the talocalcaneal joint. MRI examination showed the irregular shape and uneven signal of navicular bone, narrowing of joint space, talocalcaneal joint surface hyperplasia and cartilage destruction, tarsal joint effusion and swelling of surrounding soft tissue.@*CONCLUSION@#Muller-Weiss disease has specific imaging manifestation, and an accurate diagnosis can be made based on the patient's age, gender, and clinincal history. Preoperative imaging examination can stage the disease, help clinicians to formulate better surgical plans, and postoperative imaging examination can better evaluate the surgical effect.

Objetivos: 1) Recordar el diagnóstico de los osteomas osteoides (OO) del pie; y 2)definir las indicaciones de su tratamiento en el retropié. Material y método: Se han revisado un total de 5 osteomas osteoides (3 localizados en el astrágalo y 2 en el calcáneo). El diagnóstico se estableció por datos clínicos y de imagen. En todos los casos se identificó un nidus calcificado en la TC, edema óseo perilesional en la RM y captación focal gammagráfica. Se realizaron 2 termoablaciones con ondas de radiofrecuencia y 3 resecciones: 2 abiertas y una artroscópica. Se evaluaron los resultados clínicos y oncológicos al final del seguimiento. Resultados: No se registró ninguna complicación. El resultado clínico fue excelente en todos los casos. Un paciente fue tratado inicialmente con cirugía abierta y, después, por fracaso del procedimiento, mediante termoablación. No hubo recidivas después de un tiempo medio de seguimiento de 4 años y 6 meses (rango: 1-12 años). Discusión: Los OO del retropié son poco frecuentes y su diagnóstico se basa en la conjunción de datos clínicos con los característicos hallazgos de imagen. El tratamiento depende del asiento del nidus y de las relaciones de este con estructuras anatómicas próximas. Conclusiones: El diagnóstico de un OO del retropié puede asegurarse cuando los datos epidemiológicos, clínicos y de imagen son compatibles con la enfermedad. La termoablación está indicada en casos intracorticales o esponjosos en los que el nidus dista más de 1cm de la piel y de estructuras neurovasculares mayores. En el resto de casos una resección abierta o artroscópica sería de elección
Objectives: 1) to set a reminder of the diagnostic approach to osteoid osteomas (OOs) of the foot; 2) to define the indications of treatment for hindfoot OOs. Material and method: 5 OOs were checked (3 cases located in the talus and two cases in calcaneus). The diagnosis was established by clinical and imaging data. In all cases, a calcified nidus was identified on CT, perilesional bone oedema on MRI and focal scintigraphic uptake. Two cases were treated with radiofrequency ablation (RFA) and 3 cases with surgical resections: two open surgeries and one arthroscopic surgery. Clinical and oncological outcomes were evaluated at the end of the follow-up. Results: No complications were reported. The clinical outcome was excellent in all cases. One patient was initially treated with open surgery and then subsequently with RFA due to failure of the procedure. There were no recurrences after an average follow-up time of 4 years and 8 months (range, 1-12 years). Discussion: Hindfoot OOs are uncommon and their diagnosis is based on clinical data in conjunction with characteristic imaging findings. Their treatment choices depend on the location of the nidus and relationships with nearby anatomical structures. Conclusions: The diagnosis of an OO of the hindfoot can be ensured when the epidemiological, clinical and imaging data are compatible with this pathological entity. RFA is indicated for intracortical or cancellous cases in which the nidus is more than 1cm off the skin and significant neurovascular structures. For all other cases an open surgical resection or arthroscopic resection would be the first choice

La patología del pie y tobillo es una de las más frecuentes del sistema musculoesquelético y de gran repercusión en la calidad de vida de los pacientes. El diagnóstico preciso supone un desafío clínico importante debido a que la compleja anatomía y la función del pie dificultan la localización del origen del dolor por un examen clínico de rutina. En el estudio de la patología del pie se han utilizado técnicas anatómicas (radiografía, resonancia magnética [RM], ultrasonido y tomografía computarizada [TC]) y funcionales (gammagrafía ósea [GO], tomografía de emisión de positrones [PET] y RM). La imagen híbrida combina las ventajas de los estudios morfológicos y funcionales de forma sinérgica, ayudando al clínico en la gestión de problemas complejos. En este artículo profundizamos en la anatomía y en la biomecánica del pie y tobillo y describimos las indicaciones potenciales de las técnicas hibridas actuales disponibles para el estudio de la patología del pie y tobillo
Disorders of the foot and ankle are some of the most frequent ones affecting the musculoskeletal system and have a great impact on patients quality of life. Accurate diagnosis is an important clinical challenge because of the complex anatomy and function of the foot, that make it difficult to locate the source of the pain by routine clinical examination. In the study of foot pathology, anatomical imaging (radiography, magnetic resonance imaging [MRI], ultrasound and computed tomography [CT]) and functional imaging (bone scan, positron emission tomography [PET] and MRI) techniques have been used. Hybrid imaging combines the advantages of morphological and functional studies in a synergistic way, helping the clinician manage complex problems. In this article we delve into the anatomy and biomechanics of the foot and ankle and describe the potential indications for the current hybrid techniques available for the study of foot and ankle disease

A síndrome do navicular é uma condição que envolve o aparato podotroclear e representa uma das causas mais comuns de claudicação dos membros torácicos de equinos. Portanto, o estudo complementar da região reveste-se de grande interesse quando se refere ao diagnóstico e tratamento das claudicações dos equinos. O objetivo deste estudo foi demonstrar as diferenças dos achados imagenológicos entre a ultrassonografia e a tomografia computadorizada na avaliação das estruturas palmares do aparato podotroclear de equinos adultos e hígidos, bem como a descrição das estruturas observadas nas imagens obtidas com essas técnicas. Para isso, foram realizadas imagens de quatro peças anatômicas, as quais foram posteriormente seccionadas e utilizadas para a descrição anatômica. A utilização de peças anatômicas auxilia no conhecimento da anatomia normal, o que leva à melhor interpretação das imagens e aumenta a especificidade diagnóstica na detecção das alterações que as doenças acarretam. A ultrassonografia fornece informações relevantes quanto às estruturas estudadas, e sua associação com a tomografia computadorizada aumentou a acurácia da investigação. Apesar de o uso da tomografia computadorizada ser mais indicada para tecido ósseo, ela fornece informações importantes, podendo ser usada como uma ferramenta útil quando não se tem disponível a ressonância magnética em razão do custo ou da disponibilidade.(AU)
The navicular syndrome is a condition involving the podotrochlear apparatus and represents one of the most common causes of forelimb lameness in horses. Therefore, further study of this region is of interest when it comes to diagnosis and treatment of lameness in horses. The aim of this study was to demonstrate the differences between the imaging findings of ultrasonography and computed tomography in the evaluation of the palmar structures of the podotrochlear apparatus of healthy adult horses and description of the structures observed in images obtained with these techniques. For this, four images of four anatomical parts were performed, and subsequently sectioned and used for the anatomical description. The use of anatomical parts helps in the understanding of normal anatomy leading to a better interpretation of the images and increasing the specificity of the diagnostic for detecting changes that cause diseases. Ultrasonography provides relevant information about these structures to be studied and the association with computed tomography (CT) increased the accuracy of the investigation. Despite the use of CT being more suitable for bone tissue it provides important information and can be used as a useful tool when there is no available MRI.(AU)

Complex regional pain syndrome, reflex sympathetic dystrophy, regional, transient and migratory osteoporosis, are known as a spectrum of medical conditions that present with pain, edema, erythema, localized osteoporosis and sometimes sympathetic dysfunction. Many factors which are present in these conditions, such as clinical presentation, radiologic findings and a variety of still unclear physiopathologic mechanisms are correlated. We propose that all these conditions are different periods of the same pathology.(AU)
Síndrome doloroso regional complejo, distrofia simpática refleja, osteoporosis regional, transitoria, y migratriz, representan un espectro de alteraciones que se presentan con dolor, edema, eritema, osteoporosis localizada y en ocasiones disfunción simpática descripta en muchos sitios esqueléticos. Muchosfactores, tales como la forma de presentación clínica, los hallazgos radiológicos y la fisiopatología desconocida de estas enfermedades las correlacionan íntimamente. Proponemos entonces, mediante la presentación de uncaso clínico, que dichas entidades son estadios y presentaciones diferentes de una misma enfermedad.(AU)

The radiological changes associated with four distinct types of leg ulceration common in the tropics are reviewed. Only mild changes occurred in the tropical phagedenic group, but more marked radiological abnormalities occurred in the three chronic groups. The frequency and pattern of the periosteal reaction is the most useful guide to radiological differentiation of these groups. (AU)
