Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severely neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has an excellent functional outcome. Objective: To assess the functional outcome of acute correction of neglected Talipes-quinoa-varus deformity in adults. Methods: This is a cross-sectional, hospital–based multi-centric study. Forty patients were included in this study. Midfoot osteotomy and elongation of the Achilles tendon were performed on all patients. Data was collected using a questionnaire and the functional outcome has been assessed using the American Orthopedic Foot and Ankle Society Score (AOFAS). This score was measured before surgery and one year after surgery. Results: the mean age was 19.9 ± 4.7 years. Males were 25 (62.5%) and females were 15 (37.5%). The mean preoperative AOFAS score was 37.7 ± 7.1 (poor). This score improved to 80.7 ± 13.7 (good to excellent), two years after surgery. However, this indicates a significant change in the functional outcome after the operation (p value Conclusion: acute correction of neglected and relapsed TEV with elongation of the Achilles tendon and single midfoot osteotomy has excellent functional outcome as assessed by AOFAS Score. The satisfaction with this procedure is impressive. The younger age population showed better outcomes with this procedure.展开更多

The hyper-color force is a generalization of the SU(2)-based weak interaction and the SU(1)-based right-chiral self-interaction, in which the W-and the Z-bosons are Yukawa residual-field-carriers of the hyper-color force, in the same sense as the pions are the residual-field-carriers of the color SU(3) interaction. Using the method of numerical minimization of the SU(4)-action based on this model, the masses and the inner structure of leptons, quarks and weak bosons are calculated: the mass results are very close to the experimental values. We calculate also precisely the value of the Cabibbo angle, so the mixing matrices of the Standard model, CKM matrix for quarks and PMNS matrix for neutrinos can also be calculated. In total, we reduce the 29 parameters of the Standard Model to a total of 7 parameters.展开更多
