Objective To evaluate the outcomes of the surgical fixation of atypical femoral fractures in bisphosphonate-treated patients with an intramedullary device. Materials and methods This multicentric study was carried out at the department of orthopedics, Dr. Ruth Phau Civil Hospital and Medicare Hospital, Karachi, Pakistan, between 2013 and 2018 The primary objective of this study was to characterize serum concentrations of selected perfluorinated chemicals ( PFCs), including perfluoroctanoate (PFOA) and perfluorooctanesulfonate (PFOS), in a representative random 1/3 subset of the non-occupationally exposed US population from NHANES 1999-2000, so that we could obtain national population levels for these compounds over this two-year.

Reduction with Steinmann pin was applied percutaneously. Another cause of reduction loss is the false trochanteric entry site (16) Spike and Recovery Experiment. Analyte recoveries from rat liver, kidney, and plasma were determined by spiking tissue samples of liver (~1 g), kidney (~0.5 g), and plasma (~0.1 ml) from a control rat (n= 4) with 10 ng of 6:2 diPAPs, PFCAs, FTCAs, and FTUCAs.
