Double innominate osteotomy

The Journal of Bone and Joint Surgery. American Volume

We performed double innominate osteotomy in twenty-five patients with acetabular insufficiency resulting from congenital dislocation of the hip and other lesions. Following iliac (Salter) osteotomy, the second osteotomy was carried out medial to the obturator foramen in the interval between the symphysis pubis and the pubic tubercle. In children more than six years old, adolescents, and adults, addition of the pubic osteotomy increased the amount of acetabular rotation and coverage of the femoral head that could be achieved. An additional benefit was that the femoral head could be shifted medially, decreasing the length of the femoral lever arm. The improvement in center-edge angle in the twenty-five patients averaged 27 degrees, and the acetabular index decreased an average of 19.5 degrees. The center of the head shifted medially an average of 1.5 centimeters. Hip stability was achieved in twenty-three of the patients.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
