Semimembranosus: A Rare Muscle Herniation and Review of the Literature.

Extremity muscle hernias are rare pathologies, most of which are managed conservatively. In symptomatic cases, surgical intervention may be required. This study represents a case of a rarer muscle hernia, semimembranosus, in a 43-year-old patient and describes the surgical technique of grafting with synthetic nonabsorbable polypropylene surgical mesh as well as the review of the literature about extremity muscle hernias.

Radiographic and pathological stages of the changes at the bone-cement interface: an in-vivo experimental study.

Introduction: Chemical and physical effects of cementation cause radiographic and histological changes at bone-cement interface. These changes can be of interest in the assessment of the residual lesions and subsequent recurrences after local resection and cementation of local aggressive tumours.

Aim: The aim of the study was to evaluate the evolution and determine the stages of the changes that occur at the bone-cement interface after cementation of cavitary lesions.
