\n\nResults A correlation (r = 0.317, p = 0.015) between the extent of intraoperative derotation and mean hip rotation in stance as well as the anteversion angle measured on torsional MRI (r = 0.454, p < 0.001) was found. However, no significant correlation
was observed between anteversion angle (tMRI) and mean hip rotation in stance, either before or after FDO.\n\nConclusions Significant improvements were found in IRG after FDO, confirming the results of previous studies. There was no correlation between the anteversion measured on MRI and the mean hip rotation in stance in 3D gait analysis before or after FDO. Thus, the data suggest that if the intraoperative extent of derotation is determined only by the anteversion angle, the result will not be better after FDO. It might only help to avoid retroversion and indicate the maximum amount of femoral derotation. In this study the BTSA1 mouse extent of the intraoperative derotation was orientated at the preoperative midpoint of rotation. Based on the small, but significant correlation between the clinical midpoint and the mean hip rotation in stance in the gait analysis, determination of the intraoperative extent of derotation
according to the mean hip rotation in stance seems to give the best results.”
“Purpose Fostering ability to organize and use medical knowledge to guide data collection, make diagnostic Selleckchem Selonsertib decisions, and defend those decisions is at the heart of medical training. However, these abilities are not systematically examined prior to graduation. This study examined diagnostic justification (DXJ) ability of medical students shortly before graduation.\n\nMethod All senior medical students in the Classes of 2011 (n = 67) and 2012 (n = 70) at Southern Illinois SHP099 clinical trial University were required to take and pass a 14-case, standardized patient examination prior to graduation. For nine cases, students were
required to write a free-text response indicating how they used patient data to move from their differential to their final diagnosis. Two physicians graded each DXJ response. DXJ scores were compared with traditional standardized patient examination (SCCX) scores.\n\nResults The average intraclass correlation between raters’ rankings of DXJ responses was 0.75 and 0.64 for the Classes of 2011 and 2012, respectively. Student DXJ scores were consistent across the nine cases. Using SCCX and DXJ scores led to the same pass-fail decision in a majority of cases. However, there were many cases where discrepancies occurred. In a majority of those cases, students would fail using the DXJ score but pass using the SCCX score. Common DXJ errors are described.\n\nConclusions Commonly used standardized patient examination component scores (history/physical examination checklist score, findings, differential diagnosis, diagnosis) are not direct, comprehensive measures of DXJ ability. Critical deficiencies in DXJ abilities may thus go undiscovered.
