Review
Smart spine implants promise to stimulate healing and provide objective information about healing progression. The ability of implants to accelerate healing and provide objective data could help guide postoperative care, foster better outcomes, and reduce complications. Real-time monitoring, remote control and programming, and data analytics are actively being developed and translated into clinical practice. This article discusses advances in smart spinal implant technology and how they may aid patients and surgeons.

Review
Prosthetic nasal reconstruction provides a restorative option for patients with nasal defects, and these can be retained with a variety of methods including adhesives and implants. These prostheses can significantly improve appearance, self-esteem, and quality of life for patients and they restore many functions of the external nose. Traditional fabrication methods are often used by the skilled professionals who make these custom prostheses, but digital technology is improving the workflow for design and fabrication of silicone nasal prostheses. Nasal prosthetic reconstruction requires multidisciplinary coordination between surgeons, maxillofacial prosthodontists, anaplastologists, and other members of the healthcare team. Prosthetic treatment can be considered as an alternative to, or an addition to treatment with surgical reconstruction.

Review
Osseointegrated implants is a surgical treatment permitting a direct skeletal attachment of an external prosthesis. It is a treatment for healthy transfemoral amputated patients who cannot tolerate or use a socket prosthesis, thereby alleviating related issues with poor fit, skin problems or discomfort. This review provides a summary of the indications and contraindications for surgery, the most common implants and reported outcomes.

Review
Retinal prostheses are a promising means for restoring sight to patients blinded by photoreceptor atrophy. They introduce visual information by electrical stimulation of the surviving inner retinal neurons. Subretinal implants target the graded-response secondary neurons, primarily the bipolar cells, which then transfer the information to the ganglion cells via the retinal neural network. Therefore, many features of natural retinal signal processing can be preserved in this approach if the inner retinal network is retained. Epiretinal implants stimulate primarily the ganglion cells, and hence should encode the visual information in spiking patterns, which, ideally, should match the target cell types. Currently, subretinal arrays are being developed primarily for restoration of central vision in patients impaired by age-related macular degeneration (AMD), while epiretinal implants-for patients blinded by retinitis pigmentosa, where the inner retina is less preserved. This review describes the concepts and technologies, preclinical characterization of prosthetic vision and clinical outcomes, and provides a glimpse into future developments.

Review
Implantable microfluidics involves integrating microfluidic functionalities into implantable devices, such as medical implants or bioelectronic devices, revolutionizing healthcare by enabling personalized and precise diagnostics, targeted drug delivery, and regeneration of targeted tissues or organs. The impact of implantable microfluidics depends heavily on advancements in both methods and applications. Despite significant progress in the past two decades, continuous advancements are still required in fluidic control and manipulation, device miniaturization and integration, biosafety considerations, as well as the development of various application scenarios to address a wide range of healthcare issues. In this review, we discuss advancements in implantable microfluidics, focusing on methods and applications. Regarding methods, we discuss progress made in fluid manipulation, device fabrication, and biosafety considerations in implantable microfluidics. In terms of applications, we review advancements in using implantable microfluidics for drug delivery, diagnostics, tissue engineering, and energy harvesting. The purpose of this review is to expand research ideas for the development of novel implantable microfluidic devices for various healthcare applications.

OBJECTIVE
In a postlaryngectomy patient, tracheoesophageal (TE) speech is considered to be the most effective and preferred method of communication. Previous research has demonstrated that despite an appropriately sized TE prosthesis placement at the time of puncture, there are a portion of patients that require resizing postoperatively. The purpose of this study was to report on the variability of the tracheoesophageal prosthesis length.
STUDY DESIGN
Retrospective chart review.
SETTING
Tertiary care academic medical center.
METHODS
This was a retrospective chart review of 62 patients who underwent secondary tracheoesophageal puncture (TEP) at a tertiary care academic medical center from January 2008 to November 2019. Patient demographic information, average changes in prosthesis length, number of prosthesis adjustments, and timing of prosthesis exchanges were collected.
RESULTS
62 patients met criteria for study inclusion. Mean age was 61.96 years old with 49 being male (79%) and 13 (21%) females. Overall change in prosthesis length was - 3.85 mm ± 3.58 with time to first prosthesis change at 2.29 months ± 2.73. There was an average of 4.37 changes ± 3.43 before reaching a stable length. Twenty-six patients (41.9%) had increases in their prosthesis length resulting in closure of the tracheoesophageal fistula requiring seven patients (11.3%) to return to the operating room for repuncturing. History of smoking (P = 0.02), Blom-Singer prosthesis type (P = 0.03), and larger diameter (P = 0.01) appeared to be predisposing factors for a fluctuating prosthesis length.
CONCLUSION
Tracheoesophageal prosthesis length decreases over time for secondary punctures, requiring adjustments with a speech language pathologist. There are a clinically significant portion that have fluctuations in prosthesis length resulting in an increased risk for requiring re-puncturing.

Review
Advances in technology allowing the combination of medical imaging and three-dimensional printing have greatly benefitted thoracic surgery, allowing for the creation of complex prostheses. Surgical education is also a significant application of three-dimensional printing, especially for the development of simulation-based training models. Aiming to show how three-dimensional printing can benefit patients and clinicians in thoracic surgery, an optimized method to create patient-specific chest wall prosthesis using three-dimensional printing was developed and clinically validated. An artificial chest simulator for surgical training was also developed, replicating the human anatomy with high realism and accurately simulating a minimally invasive lobectomy.

Review
Conditions, accidents, and aging processes have brought with them the need to develop implants with higher technology that allow not only the replacement of missing tissue but also the formation of tissue and the recovery of its function. The development of implants is due to advances in different areas such as molecular-biochemistry (which allows the understanding of the molecular/cellular processes during tissue repair), materials engineering, tissue regeneration (which has contributed advances in the knowledge of the properties of the materials used for their manufacture), and the so-called intelligent biomaterials (which promote tissue regeneration through inductive effects of cell signaling in response to stimuli from the microenvironment to generate adhesion, migration, and cell differentiation processes). The implants currently used are combinations of biopolymers with properties that allow the formation of scaffolds with the capacity to mimic the characteristics of the tissue to be repaired. This review describes the advances of intelligent biomaterials in implants applied in different dental and orthopedic problems; by means of these advances, it is expected to overcome limitations such as additional surgeries, rejections and infections in implants, implant duration, pain mitigation, and mainly, tissue regeneration.
