Surgical Residents´ Results Seem to be Non-Inferior Comparing to More Experienced Surgeons in Femoral Neck Fracture Osteosynthesis.

Purpose Of The Study: Femoral neck fracture osteosynthesis is usually performed by using dynamic hip screw (DHS) or multiple parallel cannulated screws (MCS). In orthopedic surgery training, certain hip fractures are one of the most common operations performed by residents. It has been questioned, whether residents can provide as safe treatment and patient outcomes as those of more experienced surgeons.

Anterior cruciate ligament reconstruction learning curve study - Comparison of the first 50 consecutive patients of five orthopaedic surgeons during a 5-year follow-up.

Background: The goal of all surgical and orthopaedic training is to ensure necessary education and surgical skills without compromising the quality of operations or patient safety. Anterior cruciate ligament reconstruction (ACLR) is a common multi-staged orthopaedic surgical procedure with a learning curve. Previous studies focus mainly on learning or the learning curve of one surgeon and tunnel placements.

Blood volume assessment with hemoglobin subtype analysis in preterm infants.

The aim of the study was to assess plasma volume (PV) and red cell volume (RCV) in preterm infants with a liquid chromatographic hemoglobin subtype method (HbST) based on dilution of autologous fetal hemoglobin (HbF) by donor adult hemoglobin and measurement of the amount of HbF. PV determination with the indocyanine green dye dilution technique (ICG) was used as a reference method. Eight infants, median gestational age 29.
