Multicenter Study
What is the optimal salvage procedure for cut-out after surgical fixation of trochanteric fractures with the PFNA or TFN?: A multicentre study.
To evaluate the outcome after different types of revision operations for blade 'cut-out' and 'cut-through' after fixation of trochanteric fractures with proximal femoral nail antirotation (PFNA) or a trochanter fixation nail (TFN). ⋯ Based on the data from this study, we recommend THA as the only valid salvage procedure for 'cut-out' and 'cut-through' of helical blades after fixation of trochanteric fractures with the PFNA and TFN.

Multicenter Study
High reliability in classification of tibia fractures in the Swedish Fracture Register.
The Swedish Fracture Register (SFR) was started in 2011 and registers fractures of all types, treated either surgically or non-surgically. Twenty-six orthopaedic departments in Sweden are affiliated and a total of 84,000 fractures have been registered. The physician who establishes the diagnosis of the fracture registers and classifies it according to the AO/OTA classification. The accuracy of the classification of fractures is important for the reliability of the data in the SFR. This study aimed to evaluate how accurate the classification of tibia fractures in the register is. ⋯ This study shows that the accuracy of classification of tibia fractures in the SFR was substantial for the AO/OTA type (kappa=0.75) and moderate for the AO/OTA group (kappa=0.56) as defined by Landis and Koch. This degree of accuracy is similar to that in previous studies. We interpret this as meaning that the results of this study demonstrate the high reliability of the data in the SFR and enable the SFR to be used for further scientific analysis.
