The project harnessed the capabilities of a 320-slice CT scanner, one of the most sophisticated tools available in medical imaging, to conduct full-body scans of the mummies inside the lower halves of their heavy sarcophagi. Such scanners produce hundreds of thin cross-sectional images or “slices” of the body, which digital visualization experts then stack to form a comprehensive three-dimensional digital reconstruction. This digital approach permits an in-depth exploration of the mummies without risking damage to the delicate linen wrappings or the historic remains themselves.

Unlike prior efforts that relied on older scanning technologies, the modern CT scanner’s enhanced resolution has allowed for remarkable detail. The scans revealed facial features unknown until now, such as the contours of their eyelids and the exact shape of their lower lips, providing a more humanized perspective of these long-deceased priests. This breakthrough enables researchers and museum visitors alike to connect with the individuals on a deeply personal level, bridging millennia with the power of medical imaging.

Health assessments gleaned from the scans indicated that Nes-Min likely suffered from chronic lower back pain, a condition common in contemporary populations. His lumbar vertebrae showed signs of collapse consistent with natural wear and tear due to aging, a profound reminder that human physiology has confronted similar ailments across epochs. Additionally, the presence of artifacts buried with Nes-Min, including scarab beetles and fish representations, continued to shed light on burial customs and daily beliefs.

Nes-Hor’s CT images presented a different health profile, exposing severe dental pathology and advanced deterioration of the hip joint. Intriguingly, despite being from a later period, Nes-Hor was evidently older at the time of death than Nes-Min, a fact which underscores the significance of individual life experiences and health challenges faced by ancient peoples. These scans unfold personal health narratives that humanize the past and challenge assumptions about ancient lifespans and medical conditions.

Leading the imaging project, Summer Decker, PhD, the director of the USC Center for Innovation in Medical Visualization, emphasized how advancements in scanning technology have dramatically enhanced the level of detail visible today. “Previous scans could not capture the extensive and detailed information we now have, which opens up new possibilities for understanding these ancient individuals in ways previously unimaginable,” she explained. Her team’s expertise allowed them to transform raw imaging data into vivid 3D models, transcending the limitations of 2D viewing and enhancing interpretative accuracy.

Beyond digital models, the team utilized medical-grade 3D printing technologies to produce life-size replicas of key skeletal elements such as the skulls, spines, and hips of the priests, as well as the artifacts discovered with Nes-Min. These tactile reproductions provide invaluable tools not only for scientific research but also for public exhibition and educational purposes, engaging museum visitors with tangible connections to ancient history.

The “Mummies of the World: The Exhibition” at the California Science Center offers a premier venue for this display. Opening February 7, this exhibit features these newest scanned mummies, bringing never-before-seen detailed digital and physical representations to Los Angeles. According to Diane Perlov, PhD, an anthropologist and senior vice president for special projects at the center, such technological applications offer a “powerful window into the world of ancient people and past civilizations that might otherwise be lost,” enabling a deeper understanding of historical lifeways.

Keck Medicine’s innovations extend far beyond archaeology. Their 3D visualization and printing techniques are pivotal in translating clinical medical imaging—such as CT and MRI—into physical models for surgical planning and education. The process starts with hundreds of cross-sectional slices that are digitally reconstructed into three-dimensional models. Surgeons can then analyze and measure complex anatomical structures with greater precision or create accurate models to rehearse surgeries, improving patient outcomes by providing tailored treatment options based on precise anatomy.

These tangible models also have transformative effects on patient communication. According to Dr. Decker, patients holding replicas of their own organs gain new insights into their medical conditions, fostering understanding and cooperation in their treatment plans. Such technologies bridge the gap between abstract medical imaging and patient experience, demonstrating how advances originally developed for clinical care can reverberate into diverse fields such as archaeology.

The scanning project of Nes-Min and Nes-Hor epitomizes the tremendous interdisciplinary synergy between medical imaging technology, anthropology, and museology. It not only challenges preconceived notions about ancient health and lifestyles but also exemplifies how modern medical technology can stimulate fresh discoveries in humanities research. Access to nearly two dozen 3D printers at the USC Center for Innovation in Medical Visualization underscores Keck Medicine’s commitment to integrating innovation with applied science.

As “Mummies of the World: The Exhibition” showcases these ancient individuals in a new light, it epitomizes the power of technology to contextualize history in a visceral and relatable way. Each scan and print makes a silent millennia-old story visible and palpable, inviting reflection on the enduring human condition. Ultimately, this extraordinary endeavor heralds a future where continued technological advancements will deepen our connection to the past and illuminate its enduring relevance to human health and society.

Hip fractures are a major health concern, especially for older adults, with over five million individuals worldwide affected each year. These injuries can lead to severe complications, including prolonged hospitalization, decreased mobility, and even mortality. Femoral neck fractures, a common type of hip fracture, occur at the neck of the femur—an area crucial for weight-bearing during mobility. Among these fractures, a noteworthy proportion are classified as minimally displaced, where the fracture fragments remain closely aligned or only slightly separated, raising the question of the best surgical intervention.

Traditionally, surgeons have preferred internal fixation, a relatively less invasive procedure employing metal screws and plates to stabilize the fractured bone. This method has been favored for its shorter operative time and lower risk profile concerning complications like dislocation and infection. However, data have surfaced suggesting that internal fixation might not be the definitive solution, with approximately 14% of patients requiring additional surgeries, often escalating to hip replacements, within a few months post-initial intervention.

The fundamental purpose of the FASTER-Hip trial is to provide robust evidence regarding whether initial treatment via hip replacement could offer superior outcomes compared to internal fixation for these specific fractures. While Patterson acknowledges that a hip replacement is a more extensive procedure involving increased operating time and potential blood loss, he emphasizes the need for empirical data to guide clinical decisions. The discourse among surgeons indicates a divided stance on the two approaches, necessitating a clearer understanding through this research.

Patterson, representing a collaborative alliance with key researchers—including co-principal investigators Dr. Gerard Slobogean from the University of Maryland and Dr. Sheila Sprague from McMaster University—will oversee the trial’s implementation. The trial plans to recruit 600 patients aged 60 and above across 32 clinical sites spanning the United States, Canada, and Europe. This extensive geographic participation is pivotal in ensuring a diverse sample representative of the older adult population facing hip fractures.

A distinguishing characteristic of the FASTER-Hip trial is its commitment to prioritizing patient input throughout the research. Unlike conventional trials that often focus solely on clinical results of interest to healthcare professionals, this study involves direct collaboration with patients, caregivers, geriatric specialists, and rehabilitation experts. Regular meetings will be convened to ensure that the outcomes measured during the trial reflect what is genuinely valued by the patients themselves, creating a holistic assessment of surgical effectiveness.

Patient-centered research is integral to PCORI’s mission, which aims to enhance the decision-making capabilities of patients and their families. The engagement of patients in the development of study parameters is crucial, as it steers the focus toward outcomes like independence, functional recovery, and quality of life—factors that may not always be prioritized within the confines of clinical efficacy alone.

Surgeons are trained to think critically about the factors influencing surgery success; however, insights gleaned from interacting with patients have the potential to reshape the research agenda significantly. Preliminary discussions have revealed that patients place immense value on their ability to return home post-surgery, regain mobility, and maintain independence, which may conflict with the professional focus traditionally directed towards survival rates and management of postoperative complications.

The implications of the FASTER-Hip trial extend beyond academic inquiry; the findings are set to influence clinical practice guidelines that govern decision-making in surgical interventions. Renowned organizations like the Orthopaedic Trauma Association and the American Academy of Orthopaedic Surgeons have already expressed their endorsement of this patient-centered research, recognizing its potential to revolutionize how surgeons approach hip fracture management.

Ultimately, the goal is to produce rigorous evidence that equips surgeons worldwide with the information necessary to engage in meaningful discussions with patients and families. This evidence can guide the selection of surgical approaches tailored to individual patient preferences and clinical circumstances, a crucial stepping stone in promoting personalized medical care.

This noteworthy research endeavor has been provisionally approved, pending completion of PCORI’s business and programmatic evaluations and the formal issuance of a grant contract. As the FASTER-Hip trial unfolds, it promises to illuminate critical aspects of hip fracture management for older adults—a demographic that is often overlooked in clinical research but profoundly affected by the challenges associated with these injuries.

In conclusion, the USC-led FASTER-Hip trial represents a vital undertaking in the realm of orthopaedic surgery, poised to redefine treatment protocols for older adults with hip fractures. By weaving together the perspectives of healthcare providers and patient stakeholders, the trial aspires to catalyze a transformation in how surgical options are considered and implemented in real-world clinical settings, ultimately placing patient needs at the forefront of surgical decision-making.
