The aim of using circular implants is to produce additional skin in healthy parts of the body, so that new skin that is produced may be used to aid in healing injured areas that occur with plastic surgery. This study shows the amount of additional skin that is produced over time from implants, corresponding to the amount of liquid that is inside the implant membrane. The authors perform the study first on implants alone and then we place implants under the skin. Results of the first step are in agreement with previously conducted research. Second-step results are the first of their kind, because to the best of our knowledge, no similar studies have been conducted, either experimentally or numerically. Our study is motivated by wavering and inconsistent results that are obtained during real-time surgical procedures.

Introduction: Stress shielding remains a concern following total shoulder arthroplasty using press-fit short humeral stems. While the effect of alterations in implant geometry, positioning, and sizing on stress shielding have been investigated, the effects of coverage of the cortical boundary of the resection plane have not yet been fully explored. The purpose of this study was to quantify the effect of improved cortical coverage using elliptical vs.

Infertility is a prevalent problem among 10% of people within their reproductive years. Sometimes, even advanced treatment options like assisted reproduction technology have the potential to result in failed implantation. Because of the expected changes in gene expression during both in vitro and in vivo fertilization processes, these methods of assisting fertility have also been associated with undesirable pregnancy outcomes related to infertility.

Background: Distal radius fractures are prevalent in small and toy-breed dogs, presenting significant treatment challenges due to complications such as delayed union or non-union. These complications are often exacerbated by reduced vascular density at the distal diaphyseal-metaphyseal junction of the radius, which is vital for bone healing, particularly in toy and small breed dogs. Circular external fixation (CEF) is known for its effectiveness in managing acute and chronic fractures and providing temporary stabilization in humans.

The utilization of bone scaffold implants represents a promising approach for repairing substantial bone defects. In recent years, various traditional scaffold structures have been developed and, with advances in materials biology and computer technology, novel scaffold designs are now being evaluated. This study investigated the effects of a novel scaffold unit cell design (Hexanoid) through a computational framework, comparing its performance to that of four well-known scaffold designs.

Background: Achondroplasia, the most common form of rhizomelic dwarfism, occurs in approximately 1 in 25,000 individuals. Clinical features include attenuated growth, rhizomelic limb shortening, and craniofacial abnormalities. Limb-lengthening surgery is widely employed to improve quality of life.
