title: [Hip arthroplasty in the presence of proximal femoral deformity].
abstract: BACKGROUND
  Proximal femoral deformities may result in pain in the ipsilateral hip joint and profound functional disability, ultimately requiring arthroplasty.
  
  
  METHODS
  Primary hip replacement procedures in the presence of markedly altered anatomy of the proximal femur present a technical challenge for the orthopedic surgeon. The deformity and its underlying condition, whether congenital or acquired, may complicate canal preparation and affect the choices of implant, exposure and postoperative physiotherapy protocol. Furthermore, a two- or multi-stage treatment may be required, e.g. for implant removal, for femoral osteotomy or to rule out infection.
  
  
  CONCLUSIONS
  Treatment strategies must be individually tailored, respecting patient needs, the etiology, the anatomic site and the geometry of the deformity encountered, bone quality, soft tissue deficits, the presence of retained implants in the proximal femur, infection status and comorbidities.
