6-Bromo-9,9-diethyl-,-di-phenyl-fluoren-2-amine.

In the title compound, CHBrN, the dihedral angles between the fluorene fused-ring system and the pendant phenyl groups are 67.76 (12) and 88.38 (12)°.

Do Ultracongruent Inserts Reproduce the Intraoperative Sagittal Plane Kinematics of Posterior Stabilized TKR? Assessment Using a Modern Robotic System.

Background: Ultracongruent (UC) total knee replacement (TKR) designs, serving as alternatives to posterior stabilized (PS) and cruciate retaining (CR) designs, lack conclusive evidence regarding posterior femoral rollback. This study aimed to compare intraoperative posterior femoral rollback and maximal knee flexion between UC and PS inserts, addressing the paucity of literature on femoral rollback achieved with UC designs in total knee replacement.

Methods: A consecutive cohort of 20 patients undergoing robotic-assisted primary total knee replacement, posterior femoral rollback and maximal intraoperative knee flexion were assessed.

(1-Benzo-diazol-2-ylmeth-yl)di-ethyl-amine.

In the crystal of the title compound, CHN, the mol-ecules are linked by N-H⋯N hydrogen bonds, generating a (4) chain extending along the -axis direction. One of the ethyl groups is disordered over two sets of sites with a refined occupancy ratio of 0.582 (15):0.

Frederick G Banting (1891-1941): A Pioneer in Diabetes Treatment.

The discovery of insulin by Frederick G Banting and his colleagues in 1921 marked a pivotal moment in medical history. Born in Ontario, Canada, in 1891, Banting's childhood was impacted by the death of his closest friend, Jane, who died of diabetes mellitus at a young age. This personal tragedy profoundly influenced him to choose a career in medicine and fueled his determination to find a cure for diabetes.

Building a Strong Local Reputation.

Establishing a strong local reputation is essential for growing your practice. Primary care physicians, pediatricians, physical therapists, athletic trainers, and fellow orthopedic surgeons are key sources of referrals for new and old practices alike. Additionally, there is nothing better than a referral from a satisfied patient, whether it is through word of mouth to their friends and family members or publicly through an online review website.
