ABSTRACTTotal hip arthroplasty (THA) is one of the most cost-effective hip surgeries among orthopedic procedures. We conducted an extensive literature review with 5,394 papers regarding survival rates after THA. We searched PubMed, Embase and the Cochrane library from January 1st, 1970 to July 31th, 2014 looking for all citations about total hip arthroplasty with a long term follow-up (longer than 10 years). The criteria were rigorous: no loss of follow-up, and follow-up more than 10 years. The authors should have known the complete history of patients (whether the patient is alive or dead). Considering the criteria, we found only 15 papers. To evaluate the relationship between follow-up and survival, a linear regression analysis was applied. Considering the papers analysed, and applying the search criteria, we obtained a mean age for the patients above 57.5 years. The chance of survival at 15 years was 57.6%, at 20 years it was 34.6% and at 25 years it is only 11.6%. The relationship between follow-up and survival was significantly linear (p <0.001). Only 11.6% of patients undergoing THA will be still alive 25 years after the surgical procedure. Level of Evidence I, Prognostic Study.

OBJETIVO: Avaliar a consolidação pós-osteotomia osteotomia valgizante do fêmur no tratamento do pseudartrose do colo femoral. MÉTODO: Durante 15 anos (1988-2003), 32 casos de pseudartrose do colo do fêmur foram tratados com osteotomia valgizante e fixação. O seguimento médio dos casos foi de 9,8 anos e a média de idade dos pacientes foi de 41,7 anos. RESULTADOS: Dos 32 casos quatro evoluíram para prótese total do quadril e 28 evoluíram para consolidação (87,4%). Oito casos evoluíram necrose parcial. CONCLUSÃO: A osteotomia valgizante é altamente eficaz para obtenção da consolidação na pseudartrose do colo do fêmur 87,4% (28/32) A recuperação integral da função do quadril só foi obtida em 56,2% (18/32)

PURPOSE: The purpose of the present study was to review the results of femoral neck non-unions treatment with valgusing intertrochanteric osteotomy. METHODS: Between 1988 and 2003 we treaded thirty two femoral neck non-unions with valgusing osteotomy and fixation. The mean follow-up time was 9.8 years and the mean age was 41.7 years. RESULTS: Twenty eight (87.4%) of the thirty two valgusing osteotomies evolved to femoral neck union, while four cases (12.6%) evolved to total hip arthroplasty. Eight cases evolved to partial osteonecrosis. CONCLUSIONS: The valgusing intertrochanteric osteotomy for treating femoral neck non-unions achieved consolidation in 87.4% (28/32). However, only 56.2% (18/32) achieved full recovery of hip function.
