Introduction: Femoral neck fractures are a major problem in orthopaedic practice, having a huge impact on society, and involving a large number of elderly patients for whom early recovery is paramount. Thus, the aim of this study was to compare 2 surgical approaches, direct anterior (DA group) versus posterolateral (PL group), used for bipolar hip hemiarthroplasty (BHA) with femoral neck fractures in order to assess pain recovery after surgery. Our hypothesis was that early pain recovery would be faster in the DA group.
Methods: 100 patients were randomised to surgery using either a DA group or PL group approach, and were then followed up for 6 months. Surgical time, intra- and postoperative complications were recorded for each patient. The main outcome, pain, was recorded using an NRS scale at 3 days, 1, 3 and 6 months after surgery. At the same time, patient status was evaluated using Activities of Daily Living and Cumulated Ambulation Score scales.
Results: Surgical time was longer in the DA group ( 0.0001). Pain perception at 3 days and at 1 month after surgery was significantly lower in DA group patients ( 0.0001). The results of the other scales were comparable in the 2 groups (at 3 days, 1 and 3 months after surgery).
Discussion: The DA approach offers a significant advantage in terms of pain perception up to 1 month after the operation. Early recovery in terms of pain perception is an important finding. Future studies should explore whether this early pain reduction could translate into a faster rehabilitation programme for an earlier recovery of full function.Clinical trial registration: Protocol 423/CE; Study n. CE 41/15.

Delayed fracture healing (DFH), a common complication of post-fracture surgery, exhibits an incompletely understood pathogenesis. The present study endeavors to investigate the roles and underlying mechanisms of miR-656-3p and Bone Morphogenetic Protein-2 (BMP-2) in DFH. It was recruited 94 patients with normal fracture healing (NFH) and 88 patients with DFH of the femoral neck.

The socioeconomic burden of hip fractures, the most severe osteoporotic fracture outcome, is increasing and the current clinical risk assessment lacks sensitivity. This study aimed to develop a method for improved prediction of hip fracture by incorporating measurements of bone microstructure and composition derived from high-resolution peripheral quantitative computed tomography (HR-pQCT). In a prospective cohort study of 3028 community-dwelling women aged 75 to 80, all participants answered questionnaires and underwent baseline examinations of anthropometrics and bone by dual x-ray absorptiometry (DXA) and HR-pQCT.

DXA can also assess hip geometry, including femoral neck width (FNW) and hip axis length (HAL), which have both been associated with increased risk for hip fracture independently from BMD. Our objective was to assess if FNW predicts hip fracture independently from other factors including HAL.

Background: A population-based study delineating the epidemiologic, clinical, and treatment characteristics of femoral neck fractures (FNFs) in elderly patients has not yet been conducted in Turkey. In this nationwide study, the epidemiologic, clinical, and treatment characteristics of patients aged ⩾65 years with FNFs who underwent osteosynthesis, hemiarthroplasty (HA), or total hip arthroplasty (THA) were examined.
Methods: Patients aged ⩾65 years with FNFs were identified in this retrospective, nationwide study.

Osteoporosis is the most common bone metabolic unbalance, leading to fragility fractures, which are known to be associated with structural changes in the bone. Cortical bone accounts for 80 % of the skeleton mass and undergoes remodeling throughout life, leading to changes in its thickness and microstructure. Although many studies quantified the different cortical bone structures using CT techniques (3D), they are often realised on a small number of samples.
