a distal femoral supra condylar plate biomechanical comparison with condylar plate and first clinical application for treatment of supracondylar fracture
International Orthopaedics, 2012Co-Authors: Bowei Liang, Zhenqi Ding, Junguo Shen, Wenliang Zhai, Liangqi Kang, Liang Zhou, Mo Sha, Dongzhu LiangAbstract:An anatomical supra-condylar plate is designed and analysed by biomechanical testing. The biomechanical properties of the supra-condylar and condylar plate were compared in six matched pairs of cadaveric femurs. A transverse osteotomy gap was created to simulate an OTA/AO type A3 supracondylar fracture. The left and right specimens were fitted with supra-condylar and condylar plate, respectively. Nondestructive axial compression, three-point bending and torsion tests were performed, and the peak load of the bone-implant construction was measured. The fracture site suitable for supra-condylar plate application and its correlation with femoral length were calculated. The Gender Influence on it was also discussed. The difference of stiffness between the supra-condylar and condyle groups were not significant (P > 0.05) at 363.4 and 362.5 N/mm for compression, 229.5 and 237.6 N/mm in the sagittal plane and 195.5 and 188.4 N/mm in the coronal plane for three-point bending, and 7.5 and 7.9 Nm/deg for axial torsion, respectively. The peak load was 4438 ± 136.15 N and 5215 ± 174.33 N, respectively, for the two groups. The average extent of the fracture site suitable for the application of the supra-condylar plate was 70.86 ± 4.61 mm. The femoral length and Gender showed no Influence on it. Despite the limited bone contact area provided by the supra-condylar plate, its construct stiffness is comparable to the condylar plate. The supra-condylar plate can be used to treat carefully-selected extra-articular supracondylar fractures.

Gender Influence on defecographic abnormalities in patients with posterior pelvic floor disorders.
Baishideng Publishing Group Co. Limited, 2010Co-Authors: Savoye-collet Céline, Savoye Guillaume, Koning Edith, Leroi Anne-marie, Dacher Jean-nicolasAbstract:International audienceTo compare defecographic abnormalities in symptomatic men and women and to analyze differences between men and age- and symptom-matched women. Sixty-six men (mean age: 55.4 years, range: 20-81 years) who complained of constipation and/or fecal incontinence and/or pelvic pain underwent defecography after intake of a barium meal. Radiographs were analyzed for the diagnosis of rectocele, enterocele, intussusception and perineal descent. They were compared with age- and symptom-matched women (n = 198) who underwent defecography during the same period. Normal defecography was observed in 22.7% of men vs 5.5% of women (P < 0.001). Defecography in men compared with women showed 4.5% vs 44.4% (P < 0.001) rectocele, and 10.6% vs 29.8% (P < 0.001) enterocele, respectively. No difference was observed for the diagnosis of intussusception (57.6% vs 44.9%). Perineal descent at rest was more frequent in women (P < 0.005). For the same complaint, diagnosis of defecographic abnormalities was different in men than in women: rectocele, enterocele and perineal descent at rest were observed less frequently in men than in women
