The relationship between Hill-Sachs lesion and recurrent anterior shoulder dislocation
WOS: 000254244600004PubMed: 17515227The relationship between the number of shoulder dislocations and the depth and percent of head involvement of the Hill-Sachs lesions was investigated in this study. Thirty patients with recurrent anterior dislocation of the shoulder were divided into three groups according to the numbers of dislocations they had presented : Group 1 : 1 to 5 dislocations; Group 2 : 6 to 20 Group 3 : over 20. The mean percentage of head involvement was 11.9% in the first group, 25.4% in the second group and 26% in the third group of patients with Hill-Sachs lesions. The average depth of the Hill-Sachs lesions was 4.14 mm in the first group, 5.13 mm in the second group and 4.38 mm in the third group. Based on these findings, it appears that there is a correlation between the number of dislocations and the extent and depth of the Hill-Sachs lesions. Surgical treatment should therefore be performed as early as possible in patients with recurrent anterior dislocation of the shoulder, in order to prevent progression of the Hill-Sachs lesion which can become by itself a cause of instability
Computerized tomography scout view for determining distal femoral resection angle in intramedullary instrumentation of total knee arthroplasty
Cirpar, Meric/0000-0001-9669-6513WOS: 000243619300015PubMed: 16924560This study aims to investigate the results of distal femoral resection by determining the difference between mechanical and anatomical axes of femur using computerized tomography (CT) scout views in pre-operative planning of total knee arthroplasty. CT scout view of the lower extremities was taken before and after the operation in 16 patients undergoing total knee arthroplasty. Distal femoral resection was performed according to the previously determined ideal resection angle (IRA) using intramedullary instrumentation. At post-operative scanogram, femoral component deviation (FCD) was measured. The results were statistically analyzed. The average IRA was 6.95 (5-9) degrees. At post-operative measurements, the average FCD was 0.63 (0-3) degrees. CT scout films improve the accuracy in distal femoral resection and femoral component alignment
