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.

Open reduction and internal fixation (ORIF) of Bennett fractures is increasingly preferred over closed reduction and percutaneous fixation (CRIF) in an attempt to prevent the development of post-traumatic arthrosis. The aim of this systematic review was to determine whether the preference for ORIF is justified based on the available literature regarding functional outcome and complications after surgery. ⋯ The analysed data do not confirm ORIF to prevent post-traumatic arthrosis, secondly more fixation failure and pain was seen in the ORIF group. The pooled data show percutaneous fixation to be preferable over ORIF in the surgical treatment of Bennett fractures.

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.

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.

Fragility fractures of the pelvis (FFP) show a notable rise in prevalence. Minimally invasive surgical fixation of FFP is increasingly advocated for its obvious advantages with reference to early mobilization and weight bearing. Concerns regarding the holding power of osteosynthetic materials in osteoporotic bone led to the development of cementing techniques. However, the role of cement augmentation in the surgical treatment of FFP has yet to be defined. Therefore, the aim of this study was to conduct a systematic review of the current literature concerning studies that are comparing the performance of cement augmented versus non-augmented sacroiliac (SI) screws. ⋯ In clinical case series, cement augmentation of SI screws appears to be a safe surgical technique without relevant complications and biomechanical studies demonstrate greater pull-out forces of augmented SI screws but no advantage in regard of cyclic loading. Hence, applicability of the mechanical testing results on the clinical situation are debatable. So far, there are neither retrospective nor randomized controlled studies comparing the performance of cemented and non-cemented SI screws in FFP. Therefore, the clinical benefit of SI screw cement augmentation is unclear and their use remains experimental.
