Anterior approaches in acetabular fractures: a true learning curve analysis.

Today, acetabular surgeons in training have to learn ilioinguinal and anterior intrapelvic approaches (AIP). The aim of this study was to describe the 5-years learning curve of a surgeon. Objective was to assess clinical and radiological results; and to assess factors which could influence this learning curve. Between November 2015 and May 2020, patients with an acetabular fracture operated by the surgeon during the 5-years learning curve with an anterior approach were included in this single-center retrospective study based on a prospective database. Epidemiological, operative, clinical, radiological and complications data's were collected. To assess learning-curve effect the series was divided into two groups: first 2.5-years and last 2-years. Subgroup analysis were performed according to the surgical approach, to the reduction quality and the prognostic factors. In total, 46 patients were included, 23 in period 1 and 23 in period 2. 16 patients (35%) had ilioinguinal approach and 30 patients (65%) had modified Stoppa-Cole approach. At mean follow-up of 24 months, 38 patients (83%) were reviewed. Anatomical reduction (< 1 mm) was achieved in 28 patients (60.9%) with a 9% rate of perioperative complications and 37% rate of post-operative complications. In conclusion, this study gives a realistic overview of the learning curve of anterior approaches in acetabular fractures surgery. Our results should encourage surgeons, while keeping in mind how much this surgery can be challenging, with high rate of complications and difficulty to obtain a systematic anatomical reduction.

[Can caesarean delivery prevent cerebral palsy? Medico-legal implications of a French ecological study]. / La césarienne peut-elle prévenir la paralysie cérébrale ? Implications médico-légales d'une étude écologique française.

OBJECTIVE: For a long time, the benefit of a caesarean delivery in the prevention of cerebral palsy (CP) has been put forward, which was based on the assumption that CP is due to asphyxia in more than 50 % of the cases. However, from register-based data, this rate has been estimated less than 4 %. The aim of this study was to evaluate whether the rate of caesarean sections for fetal indication was correlated with the prevalence rate of CP in a French county. PATIENTS AND METHODS: This was an ecological study of register-based prevalence estimates of children with CP (postnatal cases excluded) born between 1997 and 2003 in a French county compared with the rates of caesarean section for fetal distress obtained from the maternal and infant protection service of the county. RESULTS: Whilst the rate of caesarean section for fetal indication increased by 44% during the period studied, the prevalence of CP remained nearly stable around 1.5 per 1000 live births. There was no correlation between caesarean section and CP prevalence (r'=-0.36, P=0.43). DISCUSSION AND CONCLUSION: The present study was in accordance with the results of a recent meta-analysis which concluded that emergency and prophylactic caesarean deliveries were not efficient in the prevention of CP. Indication of caesarean delivery for foetal heart rhythm anomaly, which is the most relevant cause for the growing rate of caesarean sections, should be justified by additional examinations in ambivalent cases, in order not to consider it as defensive medicine, which is ethically and therefore juridically blameworthy.
