Reversed Z-effect and Z-effect phenomena in femoral neck fracture treated with a dynamic locking plate fixation: Case report.

The aim of this case report is to present an unusual mechanism of failure of a dynamic locking plate (DLP), previously reported in dual lag screw proximal femoral nails. A 78-year-old female patient experienced a displaced right femoral neck fracture (FNF) which was managed with DLP. At the postoperative sixth-week appointment, her hip radiographs showed that two of three telescoping screws had slid within the telescrew barrel, and one screw was fully extended and cutting through the femoral head.

Factors influencing femoral neck fracture healing after internal fixation with dynamic locking plate.

Introduction: The purpose of this study was to determine factors that affect the early failure of femoral neck fracture healing after internal fixation with a dynamic locking plate implant.

Patients And Methods: Retrospective analysis of all cases of femoral neck fracture (FNF) primarily treated with dynamic locking plate implant from 04/2014 to 04/2017 with a minimum of 6 month follow-up. For the purpose of the study age, sex and time from admission to surgery were retrieved from the hospital medical database.

The levels of PCV2 specific antibodies and viremia in pigs.

Porcine circovirus 2 quantification by real-time PCR and determination of virus specific antibodies using a peptide based ELISA test was performed on a total of 400 serum samples. Samples for antibody measurement and virus quantification were obtained from a conventional pig farm with a clinical form of post-weaning multisystemic wasting syndrome. Samples were taken during the post-weaning period.
