Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut For over 4000 years, sutures have been used as a medical intervention. The earliest records indicate linen was the biomaterial of choice. Catgut, which is still in use today, was reportedly used to treat gladiators around 150 AD. Today, there are numerous materials being used for sutures. Sutures are classified by their composition (natural or...

Personalized medicine for orbital reconstruction is developing rapidly. Due to the delicate nature of the orbit, small discrepancies following fracture reconstruction may cause impairment in visual perception. Here, we describe three methods for virtual 3D reconstruction of orbital defects and their indications and potential pitfalls for correct reconstruction.

The study innovatively combines sutures and titanium needles for stable internal fixation in a rat radial fracture model. Fracture healing was assessed via micro-computed tomography (micro-CT), and primary dorsal root ganglion (DRG) neurons were isolated and cultured for further investigation.
FAQs
Larger cracks generally make failure more likely because they increase the severity of stress concentration at the crack tip. Geometry also affects how applied loads are distributed through a component. Consequently, two specimens made from the same material can exhibit different fracture strength when their crack dimensions or structural shapes differ.
Material toughness describes a material’s resistance to crack growth, so it helps determine how much damage can be tolerated before unstable propagation occurs. Fracture strength should therefore be interpreted alongside toughness rather than as an isolated value. This distinction is important when comparing candidate materials for load-bearing biomedical designs.
Fracture strength depends on the conditions under which stress is applied, including the mechanical loading experienced by a component. In bioengineering, the relevant conditions may also include physiological loading associated with use in the body. Matching the evaluation conditions to the intended environment improves predictions of structural reliability and failure.
A meaningful evaluation should account for crack size, material toughness, specimen or component geometry, and the applied loading conditions. These variables govern the stress intensity at a crack tip and determine whether crack growth remains stable or becomes uncontrollable. Controlling or documenting them makes comparisons between materials and designs more informative.
Comparing fracture strength helps researchers assess metals, ceramics, polymers, and composites for implants and other biomedical devices. The comparison should reflect each material’s toughness, geometry, crack condition, and intended loading environment. Results can identify materials or designs better suited to reliable structural performance under mechanical or physiological demands.
For tissue-engineered scaffolds and implants, fracture-strength evaluation provides evidence about whether a structure can withstand its expected loading without catastrophic crack propagation. The findings support safer designs, more durable materials, and improved prediction of failure. They also connect material selection and structural geometry with the reliability required in biomedical applications.
