title: The role and efficacy of retrograding nailing for the treatment of diaphyseal and distal femoral fractures: a systematic review of the literature.
abstract: The aim of this analysis has been to evaluate the efficacy of retrograde nailing in the treatment of distal femur and femoral shaft fractures. Articles were extracted from the Pubmed database and the retrieved reports were included in the study only if pre-specified eligibility criteria were fulfilled. Moreover, a constructed questionnaire was administered, aimed at assessing the quality of the outcomes. Twenty-four articles were eligible for the final analysis, reviewing a total of 914 patients (mean age of 48.8 years) who sustained 963 distal and diaphyseal femoral fractures. The overall mortality rate was 5.3%. The incidence of infection was 1.1% and for septic arthritis of the knee was 0.18%. In patients with distal femoral fractures, the mean time to union and rate to union were 3.4 months and 96.9%, respectively. The mean range of knee motion was 104.6 degrees . The rates of knee pain, malunion and re-operations were 16.5, 5.2 and 17%, respectively. Patients with femoral shaft fractures had a mean time to union 3.2 months, whilst the rate of union was 94.2%. The mean range of knee motion was 127.6 degrees . The rates of knee pain, malunion and re-operations were 24.5, 7.4 and 17.7%, respectively. We concluded that retrograde intramedullary nailing appears to be a reliable treatment option, mainly for distal femoral fractures. However, in the management of diaphyseal fractures, retrograde intramedullary nailing is associated with high rates of knee pain and lower rates of fracture union.
