Isolated rupture of the popliteus muscle seems to be extremely rare, with only two cases described in the English literature. We present two cases of magnetic resonance imaging-verified isolated rupture of the popliteus muscle in polo players with the same injury mechanism-external rotation trauma on a flexed knee. Functional testing of the popliteus muscle in the figure of four position was positive in both cases. Full recovery was observed after 6 weeks of physiotherapy.
A-21-year old male admitted with fever and piriformis syndrome, typically associated with gluteal region pain radiating down the thigh, was evaluated and found to have pyomyositis involving piriformis and osteomyelitis with sacroiliac joint affection on radiological imaging. Salmonella serotype typhi was isolated from blood culture. He was treated with intravenous Ceftriaxone for 6 weeks with signs of recovery documented clinically as well as on imaging studies. Salmonella pyomyositis with osteomyelitis in an immunocompetent patient with no previous hematological or endocrine disorder makes this case an unusual presentation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
