Case report: A rare case of pure tibio-talar dislocation without malleolar clamp fracture in a young athlete: Long-term functional results and recent reviews of the literature.

Introduction And Importance: Ankle dislocation without fracture is an extremely rare injury, requires high-energy trauma, up to 1995, only 73 cases were reported in the literature and 154 cases up to 2017. It is therefore a post-traumatic ankle disease growing in parallel with the increase in road-traffic accidents requiring the study of incriminated factors such as hypoplasia of the medial malleolus.

Case Presentation: The authors report the case of a young patient, a football player, who presented with a pure, closed dislocation of his ankle following a road-traffic accident.

[Osteoid osteoma of the upper extremity of the radius: rare localization and literature review (about a case)].

Osteoid osteoma is a benign but painful bone tumor whose treatment is based on complete surgical resection. We here report the case of a young patient with osteoid osteoma of the upper extremity of the radius through a literature review.

The majority of conversion total hip arthroplasties can be considered a primary replacement: a matched cohort study.

Background And Study Aims: The success of conversion total hip arthroplasty (THA) among primary THA and revision THA remains unclear. We hypothesized that most conversion THA's can be performed using primary implants and will have an uncomplicated post-operative course.

Materials And Methods: Thirty-six patients (23 females, mean age 68,0y) who underwent conversion THA for failed interventions for proximal femur fractures in the period 2008-2018 were matched sequentially against patients of the same sex and age who underwent primary THA or revision THA.

Sclerosing epithelioid fibrosarcoma: rare and serious.

Sclerosing Epithelioid Fibrosarcoma (SEF) is a rare form of soft tissue sarcoma. It is characterized by a slow evolution, with local recurrences and late metastases that are mainly pulmonary and pleural in about 50% of cases. The treatment is based on the surgery which must be as wide as possible.
