Acetabular erosion following bipolar hemiarthroplasty: A Role for the size of femoral head?
Femoral neck fractures are the most frequent fractures in the elderly and hemiarthroplasty is the treatment of choice. The objective of this study is to identify predictive factors of acetabular erosion after bipolar hemiarthroplasty in a mobile independent population during a follow-up of ten years. ⋯ In bipolar hemiarthroplasty smaller head size lead to a polar wear implying a higher risk of acetabular erosion and migration; in our population this risk was consistent with the use of implant head < 48 mm diameter. Considering the absolute risk of a smaller FH size, the surgeon must evaluate the accuracy of measurement of the caliber, since as reported in previous studies, it can significantly underestimate the size.

Multicenter Study
Retrospective, multicenter evaluation of complications in the treatment of diaphyseal femur fractures in pediatric patients.
Femoral shaft fractures are the commonest major pediatric fractures. For generations, traction and casting were the standard method of treatment for children. However, over the past two decades there has been growing recognition of the advantages of fixation and rapid mobilization. ⋯ TEN are an excellent internal fixation system if used by an expert surgeon and have a very low rate of complications. None of them produced permanent damage in the patients. In older children weighing more than 50 kg, alternative techniques such as subtrochanteric nailing, plates, or external fixation are advisable.

Multicenter Study Comparative Study
Comparison of plate, calcanealplasty and external fixation in the management of calcaneal fractures.
Managing displaced intra-articular calcaneal fractures remains controversial. The purpose of this study is to compare and identify the surgical technique with the best outcomes for the treatment of intra-articular calcaneal fractures. ⋯ Displaced intra-articular calcaneal fractures are still technically demanding injuries to manage. The results of this study suggest that in comparison to open reduction, a percutaneous reduction and fixation leads to higher but not statistical functional scores minimizing the wound-healing complications.
