A 29-year-old athlete suffered from vague hip pain during the preparation for a marathon competition. During the competition, severe pain forced him to drop out after 29 kilometres. He underwent conventional x-rays immediately, which showed a displaced lateral fracture of the femoral neck. The fracture was immediately treated with a dynamic hip screw. A few days later, the patient was discharged. He returned to sport upon completion of treatment. Vague hip pain after exercise may be an indicator for a rare stress fracture of the femoral neck and should be taken into consideration in athletes. Delayed diagnostic investigation and treatment reduce return-to-sport rates and outcomes.

Higher strength and higher ductility are desirable for structural materials. However, ultrastrong alloys inevitably show decreased strain-hardening capacity, limiting their uniform elongation. We present a supranano (<10 nanometers) and short-range ordering design for grain interiors and grain boundary regions, respectively, in fine-grained alloys based on vanadium, cobalt, and nickel, with additions of tungsten, copper, aluminum, and boron.

Chronic exposure to stress has been considered a risk factor for hypertension, which is also associated with increased bone resorption. This review aimed to investigate the effect of acute and chronic stress, associated with hypertension, on the skeletal system. A comprehensive search was conducted across multiple databases, focusing on peer-reviewed articles published in English.

Background: Bisphosphonate-associated stress fractures, atypical femur fractures (AFF), are a rare subgroup of femoral stress fractures. Their correct and early diagnosis is imperative for appropriate treatment.
Purpose: To investigate the sensitivity of written radiology reports to mention radiographic features of AFF, depending on the time period and academic level of the hospital.

Fiber-based artificial muscles are soft actuators used to mimic the movement of human muscles. However, using high modulus oxide ceramics to fabricate artificial muscles with high energy and power is a challenge as they are prone to brittle fracture during torsion. Here, a ceramic metallization strategy is reported that solves the problem of low torsion and low ductility of alumina (AlO) ceramics by chemical plating a thin copper layer on alumina filaments.

Atypical femoral fractures (AFF) are rare stress fractures with specific diagnostic criteria, as outlined in a report published by the American Society for Bone and Mineral Research. These criteria are categorized into major and minor features, and AFF can be classified as either complete or incomplete. Bisphosphonates have been shown to increase the risk of AFF, and most cases of AFF are associated with bisphosphonate use.
