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.

Carpal antelunar dislocation and Fenton syndrome: Extremely rare association.

Carpal antelunar dislocations are much rarer than posterior dislocations. Their frequencies are between 3 and 6% of carpal perilunar dislocations. Out of 23 cases of carpal antelunar dislocations listed in the literature, there are only 11-scapho antelunar dislocations.

[Patellar tendon rupture with distal closed fracture of the ipsilateral femur].

We here report the case of a 45-year old patient who had injured his right knee because of a road accident. The patient had right comminuted supracondylar femur fracture and ipsilateral patellar tendon rupture. This association is exceptional and no case has been reported in the literature.
