Background: Bone fractures represent a global public health issue. Over the past few decades, a sustained increase in the number of incidents and prevalent cases have been reported, as well as in the years lived with disability. Current monitoring techniques predominantly rely on imaging methods, which can result in subjective assessments, and expose patients to unnecessary cumulative doses of radiation.

The deltoid ligament (medial collateral ligament) and the syndesmosis (a composite ligamentous structure at the distal tibiofibular junction) are critical for maintaining ankle stability. In cases of high-energy ankle fractures, these structures are often injured simultaneously, leading to instability and potential long-term complications such as post-traumatic arthritis. This review aims to explore advancements in minimally invasive techniques for the treatment of combined deltoid ligament and syndesmosis injuries, with a focus on optimizing surgical outcomes and reducing patient morbidity.

Bone tissue engineering is a promising field that aims to rebuild the bone tissue using biomaterials, cells, and signaling molecules. Materials like natural and synthetic polymers, inorganic materials, and composite materials are used to create scaffolds that mimic the hierarchical microstructure of bone. Stem cells, particularly mesenchymal stem cells (MSCs), play a crucial role in bone tissue engineering by promoting tissue regeneration and modulating the immune response.

Acoustically probing biological tissues with light or sound, photoacoustic and ultrasound imaging can provide anatomical, functional, and/or molecular information at depths far beyond the optical diffusion limit. However, most photoacoustic and ultrasound imaging systems rely on linear-array transducers with elevational focusing and are limited to two-dimensional imaging with anisotropic resolutions. Here, we present three-dimensional diffractive acoustic tomography (3D-DAT), which uses an off-the-shelf linear-array transducer with single-slit acoustic diffraction.

An unusual case of small bowel obstruction (SBO) due to haemostatic gelatin sponge placed during caesarean delivery is presented. A primigravida in their 30s underwent caesarean delivery at 39 weeks, and developed symptoms of SBO from the second postoperative day. Given the worsening condition of the patient and increasing abdominal girth, CT of the abdomen and pelvis was done which revealed features of SBO.
