Dr. Assenmacher studies a range of issues related to injuries in sports and pediatric cases, along with the interactions of medical implants in the body. He has explored nerve and blood vessel injuries in the arms and hands, emphasizing the importance of quick diagnosis to help athletes recover swiftly. Additionally, he has investigated the healing processes of open fractures in children, offering insights into effective treatment methods. Beyond sports and pediatric care, he also researches innovative techniques for removing harmful radioactive materials from nuclear waste, aiming to enhance the safety of environmental management.
Key findings
In the study on palladium-catalyzed cross-coupling, researchers achieved a success rate of 81% to 95% in creating new compounds for nuclear waste management.
For open fractures of the tibia in children, 77% of the fractures healed in about 16 weeks, with only 1% failing to heal after an average follow-up of 14 months.
The investigation of titanium deposition in lymph nodes demonstrated that dogs with titanium implants had significantly more titanium particles in their lymph nodes, indicating the movement of implant material without causing inflammation.

Plain English This study explored a method for creating new chemical compounds that can effectively remove harmful radioactive elements from nuclear waste. Researchers found that they could create these compounds with high success rates—between 81% and 95%—and some of the new compounds were particularly effective at separating americium (Am(3+)) from europium (Eu(3+)), achieving a separation factor of up to 40. This is significant because it could help improve the safety and efficiency of managing nuclear waste.
Who this helps: This helps scientists and engineers working on nuclear waste management.

Nuber GW, Assenmacher J, Bowen MK
Plain English This study looked at common nerve and blood vessel injuries in the forearm, wrist, and hand. It found that while these injuries are not often seen in athletes, knowing how to identify and treat them quickly is crucial to prevent long-term damage. If doctors miss diagnosing these issues, athletes could face weeks or even months away from their sport.
Who this helps: This helps athletes and sports medicine doctors.

Plain English This study looked at 83 children with open fractures of the tibia, focusing on how well different treatment methods worked. After an average follow-up of 14 months, 77% of the fractures healed in about 16 weeks, and only 1% didn't heal at all. The findings indicate that treating these fractures with a combination of cleaning, fixation, and casting gives good results, and it's often better than using external fixation, which has more complications.

Plain English In this study, researchers looked at how titanium from implants affects nearby lymph nodes in dogs after dental implants were placed. They found that the lymph nodes of dogs with titanium implants contained significantly more titanium particles compared to those without implants, indicating that tiny bits of titanium were likely transported there without causing any inflammation. This is important because it helps us understand how metal implants interact with the body and the potential consequences for patient health.
Who this helps: This information benefits doctors and patients receiving titanium implants, as it clarifies the biological effects of these materials.
