Place: Germany; International audience; PURPOSE: Double level osteotomy (DLO) (femoral and tibial) is a technically demanding procedure for which pre-operative planning accuracy and intraoperative correction are key factors. The aim of this study was to assess the accuracy of the achieved correction using patient-specific cutting guides (PSCGs) compared to the planned correction, its ability to maintain joint line obliquity (JLO), and to evaluate clinical outcomes and level of patient satisfaction at a follow-up of two years. METHODS: A single-centre, prospective observational study including 22 patients who underwent DLO by PSCGs between 2014 and 2018 was performed. Post-operative alignment was evaluated and compared with the target angular values to define the accuracy of the correction for the hip-knee-ankle angle (ΔHKA), medial proximal tibial angle (ΔMPTA), lateral distal femoral angle (ΔLDFA), and posterior proximal tibial angle (ΔPPTA). Pre- and post-operative JLO was also evaluated. At two year follow-up, changes in the KOOS sub-scores and patient satisfaction were recorded. The Mann-Whitney U test with 95% confidence interval (95% CI) was used to evaluate the differences between two variables; the paired Student's t test was used to estimate evolution of functional outcomes. RESULTS: The mean ΔHKA was 1.3 ± 0.5°; the mean ΔMPTA was 0.98 ± 0.3°; the mean ΔLDFA was 0.94 ± 0.2°; ΔPPTA was 0.45 ± 0.4°. The orientation of the joint line was preserved with a mean difference in the JLO of 0.4 ± 0.2. At last follow-up, it was recorded a significant improvement in all KOOS scores, and 19 patients were enthusiastic, two satisfied, and one moderately satisfied. CONCLUSION: Performing a DLO using PSCGs produces an accurate correction, without modification of the joint line orientation and with good functional outcomes at two year follow-up.

International audience; PURPOSE: The gold standard for intramedullary nailing (IMN) in humeral shaft fracture treatment is bipolar interlocking. The aim of this study was to compare clinical and radiographic outcomes in two cohorts of patients treated with IMN with or without distal interlocking. We hypothesized that there was no significant difference between isolated proximal interlocking and bipolar interlocking in terms of consolidation and clinical results.METHODS: One hundred twenty-one acute humeral shaft fractures were retrospectively included in group WDI (without distal interlocking screw, n=74) or in group DI (with distal interlocking screw, n=47). One hundred six patients (87.60%) could be verified by an X-ray, and 63 (52.07%) could be examined clinically. Fracture union at 6months was the primary outcome, and the second was the final clinical outcome for shoulder and elbow after at least 6months of follow-up. Pain, operating time, and radiation time were also analyzed.RESULTS: The two groups were not significantly different for population, fractures, or immobilization duration. No significant difference was found for bone union (WDI 89.06% vs DI 83.33%, p=0.51), shoulder or elbow functional outcomes, or pain. However, there were significant differences in advantage to the WDI group for operating time (WDI 63.09±21.30min vs DI 87.96±30.11min, p

International audience; PURPOSE:In practice, obesity leads to poor functional outcomes after total hip arthroplasty (THA). However, in clinical research, the influence of body mass index (BMI) on the gait recovery and kinematics for THA is not well documented. The purpose of this study was to assess the influence of BMI on gait parameters pre-operatively and six months after THA for hip osteoarthritis (OA) patients.METHODS:We included 76 THA for hip OA: non-obese group (G1): 49 (BMI

International audience; PURPOSE: We assumed that the combination of dual-mobility total hip arthroplasty (THA) using the minimally-invasive Röttinger anterolateral approach could guarantee hip stability with faster functional recovery. We objectively analyzed functional improvement after dual-mobility THA by quantitative gait analysis.METHODS: We compared the results achieved following two different surgical approaches: Röttinger's versus Moore's approach (posterolateral approach). We included 70 patients in an open prospective single-centre study: 38 by Rottinger's approach (age = 67yo) and 32 by Moores's approach (age = 68yo). Clinical and biomechanical analysis (kinematic and kinetic parameters of the hip) were conducted at the pre-operative period and at six months post-op RESULTS: We found a significant improvement in all clinical scores and all biomechanical parameters but no difference was found between the two approaches. However, the study showed marked clinical, biomechanical and functional improvements for patients treated with dual-mobility THA for osteoarthritis without complete hip recovery compared with a control group.CONCLUSIONS: The combination of the Röttinger approach with a dual-mobility cup remains a valid choice for primary THA without functional advantage at midterm.
