Abstract

It appears that trochanteric fractures are always a challenge, as the risk of mortality at 1 year and the rates of complications are considerably high. During the last 20 years, various hardware improvements have been made, with the same goal: to obtain sufficient stability of the assembly to allow the resumption of support as early as possible. Sometimes, the consolidation is lacking causing serious functional damage in the elderly. Total hip arthroplasty has been advocated as a recovery procedure after treatment failure. We initiated a work in the main objective and to give back to the old subject any possibility of recovering as quickly as possible his autonomy. 22 patients benefitted from a prosthetic replacement, 12 of first intention and 10 after failure of conservative treatment. The acetabular cups were cemented with 2 retentive cups, 18 dual-mobility and 02 standard. Implantation of the prosthesis took an average of 45 minutes. One patient died during hospitalization, another patient within 90 days. The results were very good and good for the other patients.2 dislocations occurred postoperatively. The publications on this subject generally report only a very limited number of cases and are few in number. Our study shows that total hip arthroplasty is a reliable technique to treat the complications of osteosynthesis of fractures per and under -trochanteric in the elderly. The complexity of the fracture associated with other factors related to the patient himself may lead the surgeon to consider arthroplasty as the treatment of choice.
