Objectives: The purpose of this study is to report and interpret a feature on the anterolateral surface of the proximal femurs of the Krapina hominid collection that we briefly described in 2006 (Periodicum Biologorum, 108, 319-329).
Materials And Methods: We recorded the presence or absence of the feature in all the proximal femurs of the Krapina collection (six specimens recordable) and in 622 modern human adult femurs.
Results: The feature consists in a series of crests delimitating three raised or depressed areas. This feature has been found in three out of four adult Neandertal femurs observable. The two observable subadult Neandertal femurs do not show this character. None of the modern femurs displayed the feature.
Conclusion: We interpret this feature as a muscular imprint, probably representing the m. vastus intermedius origin and discuss a possible interpretation. We did not find any other references for such imprint in the existing literature regarding the Neandertal femurs.

Osteoporotic hip fractures are a considerable cause of pain and disability particularly among the elderly. Osteoporosis causes loss of bone stability, which in turn leads to an increased risk of fractures especially in metaphyseal bone. Moreover, the body's capacity for healing is diminished, resulting in prolonged recovery times following these fractures.

Sickle cell disease is the most common serious genetic disease in the world. It is a systemic disease, characterized by vaso-occlusive phenomena, especially in the bone capillary network. Orthopedic complications are thus the most common, with a strong impact on quality of life.

Unlabelled: REMS-BMD by radiofrequency echographic multispectrometry is primarily determined by a patient's BMI, age, and sex. Only about 2.8% of the changes in femoral neck REMS-BMD can be attributed to replacement of the total hip with metal implants.

Purpose: This study aimed to compare the clinical outcomes and cost-effectiveness of two widely used intramedullary fixation systems-the Proximal Femoral Nail Antirotation (PFNA) and the Proximal Femoral Nail with Talon Locking System (PFN-TLS)-in the treatment of intertrochanteric femur fractures (ITFF).
Methods: A retrospective cohort study was conducted on 118 patients aged 65-90 years who underwent surgical treatment for ITFF using either PFNA (n = 53) or PFN-TLS (n = 65). All patients were followed for a minimum of 24 months.

Atraumatic bilateral osteonecrosis of the femoral head (ONFH) is a rare phenomenon whose etiology is not fully understood. In this report, we describe the case of a 75-year-old female patient who developed rapidly onset bilateral ONFH after intra-articular corticosteroid injections. She was treated with staged bilateral total hip arthroplasty.
