title: [Arthroplasty after failed osteosynthesis in hip fractures].
abstract: OBJECTIVE
  To assess the functional status of patients with arthroplasty after failed osteosynthesis in hip fractures.
  
  
  METHODS
  Prospective, descriptive, cohort of patients with primary failed osteosynthesis in hip fracture, who underwent total arthroplasty in the period 2002-2004, analyzed with the Harris functional scale.
  
  
  RESULTS
  26 patients: 17 women and 9 men, mean age of 74.8 years. Seventeen patients had loosening of dynamic hip screw, 5 of condylar screw 5 and 4 with cannulated screws. We made 12 hybrid, 10 cemented and 4 not cemented arthroplasties. Eighteen patients with good results, 7 with regular and 1 bad result. Patients with the highest rating were the youngest.
  
  
  CONCLUSIONS
  Arthroplasty of the hip in a patient with failed osteosynthesis should be considered necessary. If we can improve pain of the hip, the patient will have less functional limitation and a better quality of life. This type of surgery requires high technical capability and experience by the orthopedic surgeon.
  
  
  CONCLUSIONS
  Hip arthroplasty after failed osteosynthesis in hip fractures is a method that improves function and a gives a better life quality.
