This is a case report of a 51-year-old woman with bilateral stress fractures of the pelvic rami and a history of anorexia nervosa (AN). AN is a psychiatric condition of low weight caused by restricted food intake, impaired body image and an exaggerated fear of gaining weight in addition to compensating behaviour such as excessive physical activity. Among patients with AN, reduced bone density is common, and a higher risk of fractures is present. Stress fractures should be suspected in patients, who have AN and experience pain from the musculoskeletal system without a history of trauma.

The best treatment method for reverse obliquity intertrochanteric fractures (ROIFs) is still under debate. Our team designed the modified proximal femoral nail (MPFN) specially for treating such fractures. The objective of this research was to introduce the MPFN device and compare the biomechanical properties with Proximal Femoral Nail Antirotation (PFNA) and InterTAN nail via finite element modelling.

A patient in his 40s presented at the outpatient clinic with sudden pain and swelling over his medial malleolus, 16 weeks after he had undergone osteoperiosteal autografting with a medial malleolar osteotomy for his tertiary osteochondral lesion of the talus. Postoperatively, the patient was treated using the regular evidence-based rehabilitation protocol of 5 weeks of non-weight-bearing and 5 weeks of partial weight-bearing. However, after the confirmed radiological union the patient experienced an acute on chronic stress fracture through the osteotomy line.

HIV-related mortality has fallen due to scale-up of antiretroviral therapy (ART), so more women living with HIV (WLH) now live to reach menopause. Menopausal estrogen loss causes bone loss, as do HIV and certain ART regimens. However, quantitative bone data from WLH are few in Africa.

As hydraulic fracturing becomes increasingly prevalent in the oil and gas industry, there is a growing need to develop more cost-effective and sustainable technologies, particularly concerning the materials used. Proppants play a vital role in hydraulic fracturing by ensuring that fractures remain conductive and can withstand the pressure exerted by the surrounding strata. One key parameter for evaluating proppants is their compressive strength, especially under harsh environmental conditions.

Background: Acromial stress fractures can occur after reverse total shoulder arthroplasty (RTSA). We performed this study to assess the incidence, risk factors, characteristics, and outcome of acromial stress fractures and reactions after RTSA.
Methods: We determined the incidence of acromial stress fractures and reactions in a cohort of patients who underwent RTSA, and assessed risk factors using a case-control design.
