[Risk of refracture according to the FRAX score in patients older than 50 years who suffer a fracture by a low-impact mechanism].

Introduction: as the population pyramid inverts, we'll see more old patients suffering a fracture secondary to a low impact mechanism and not all hospitals have a densitometer to make a definitive diagnosis. Nevertheless, we have clinical tools that can help us to start an early treatment.

Objective: to recognize the risk of re-fracture of patients older than 50 years in our population.

[Bone tissue response to the echelon-type uncemented femoral component in revision total hip arthroplasty (THA)].

Introduction: We present the preliminary, short-term results of a cohort study of revision THA focused on aseptic loosening and aimed at assessing the metadiaphyseal bone ingrowth biological response of an uncemented femoral implant with an extensive porous coating.

Material And Methods: The clinical, X-ray and personal satisfaction outcomes (SF-36) of four patients were assesessed. We had performed four exchange THAs due to a diagnosis of clinical and radiographic aseptic prosthetic loosening, with symptoms of anterior thigh pain.
