Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has various known complications in its natural course of the illness. Pneumothorax is one of the emerging complications in coronavirus disease 2019 (COVID-19)-positive patients, not initiated on invasive mechanical ventilation. Case studies and autopsy reports across the globe suggest alveolar pathology to be responsible for the outcome.COVID-19 infection in humans caused by the SARS-CoV-2 virus has various known complications in its natural course of the illness. Pneumothorax is one of the emerging complications in COVID-19-positive patients. Prior identification and anticipation of such life-threatening complications aid in the treatment of COVID-19-positive patients.

Background: The femoral neck anteversion (FNA) also known as femoral torsion can be defined as the angle formed by the femoral condylar plane and a plane passing through the centre of the femoral neck and head. The change in the angle of femoral anteversion is associated with various clinical conditions. The data established in this study will be useful for various orthopedic procedures like arthroplasties, evaluation of pathologic conditions of the hip.Aim: To measure the angle of anteversion of femoral neck and determine the variation of this angle on both the sides.Materials and Methods: 90 dry femora 45 right and 45 left devoid of any gross pathology were obtained from the department of anatomy, M S Ramaiah Medical College. The angle of femoral neck torsion was measured using goniometer in 90 dry bones were measured by Kingsley Olmsted method. The results obtained were tabulated and statistically analyzed.Results: The mean femoral neck anteversion angle for right femur was 12.09° ± 4.56°, and for left femur it was 12.53° ± 3.28°. Statistical analysis revealed the difference of means of FNA angle between the right and left femora was statistically non significant (p=0.65). Femoral anterversion was observed in 72.22% of bones while 27.77% bones showed retroversion. Conclusion:The morphology of proximal end of femur is of special interest because of susceptibility of this area to numerous disorders in adults and in paediatric age group and the treatment needs a detailed anatomical knowledge of angle of femoral neck torsion.
