Knee Osteonecrosis After SARS-CoV-2 Virus Infection.

ABSTRACT: Osteonecrosis after COVID-19 infection is a complex pathology with multifactorial origin. Factors such as infection itself with associated coagulopathy, as well as genetic mechanisms, and medications used for its treatment such as corticosteroids, may also be involved. The variability in the presentation makes diagnosis difficult, which, if done soon, can help delay progression and reduce morbidity and the need for surgery.This report presents a case of knee osteonecrosis in a female patient who did not have previous knee pathology on imaging tests. She was diagnosed by magnetic resonance imaging months after hospital admission for SARS-CoV-2 pneumonia, which required high-dose corticosteroid treatment.

Síndrome de Haglund. A propósito de 2 casos / Haglund's syndrome. Two case reports

El síndrome de Haglund es una causa de atrapamiento tendino-bursal posterior del talón, producida por una exostosis posterosuperior del calcáneo, denominada deformidad de Haglund, asociada a tendinitis aquílea y bursitis retrocalcánea. Su patogenia es desconocida. Se presentan 2 casos, diagnosticados clínicamente, confirmados radiológicamente, y tratados conservadoramente uno y con cirugía el otro. El diagnóstico se realiza por la clínica y por las imágenes radiológicas con el método de medición de las líneas de inclinación paralelas, en una radiografía lateral del tobillo. El tratamiento inicial suele ser conservador e incluye antiinflamatorios o analgésicos, fisioterapia y zapatos con talón abierto y sin tacón alto. Si el tratamiento conservador no alivia el dolor, puede ser necesaria la cirugía (AU)

Haglund's syndrome produces posterior impingement of the heel, which is caused by a posterosuperior calcaneal exostosis, known as Haglund's deformity, associated with Achilles tendinitis and retrocalcaneal bursitis. Its pathogenesis is unknown. We report two cases that were diagnosed clinically and confirmed radiographically. One patient was treated conservatively and the other underwent surgery. The diagnosis is based on clinical signs and radiological images, using the measurement of the parallel pitch lines, in a lateral radiograph of the ankle. Initial treatment is usually conservative and includes anti-inflammatory or analgesic agents, physiotherapy and low-heeled, open-heeled shoes. If conservative treatment does not relieve the pain, surgery may be necessary (AU)
