Modern surgery, medical implants & medical prostheses

Surgery, implants and prostheses are fundamental components of modern medicine. Surgery refers to operative procedures used for diagnosis, treatment or prevention of diseases. Precise techniques and state-of-the-art imaging play a key role in carrying out interventions as gently and effectively as possible. 

Implants are aids that are permanently or temporarily inserted into the body to replace, support or stabilize damaged structures. They are used in disciplines such as dentistry, orthopaedics (hip and knee joints), cardiology (pacemakers) and neurosurgery. In this way, they make a significant contribution to restoring bodily function and quality of life. 

Prostheses replace missing body parts, such as limbs or breast tissue, and make an important contribution to mobility and independence. They not only enable the recovery of physical abilities, but also promote mental stability, self-awareness and social participation. 

The three areas complement each other closely: surgeons insert surgical implants into the body, enabling functions that would not be possible without technology. They take over functions of body parts, surgically prepared and accompanied, while implanted systems remain permanently in the patient. Modern concepts such as digital planning, health robots and individualized production are constantly optimizing the effectiveness of these aids. 

Progress is particularly evident in the field of prostheses: new technologies make them more functional, lighter and more comfortable, progress that directly improves the quality of life of those affected. Traditional mechanical systems have been replaced by systems with microchips and sensors that enable finer movements. This means that changes in terrain such as climbing stairs, walking uphill or stopping abruptly can be automatically detected and processed. 

The choice of materials plays an equally important role: carbon fiber composites, silicone and thermoplastics provide low weight, high resilience and comfortable wearability. Thanks to modern production methods, designs can also be highly individualized, which has a positive effect on the feeling of the body shape. 

Rehabilitation and everyday life benefit greatly from these developments: Patients achieve faster progress in mobility and musculature, as modern prosthetic devices support physiological gait and balance. The psychological aspect should not be underestimated, especially in the case of visible prostheses: a natural appearance enhances self-esteem and supports social reintegration. There are also specialized solutions for sporting activities, such as running or swimming, which are designed to withstand high levels of strain. 

A key trend is increasing personalization through digital planning and production. The combination of imaging and additive manufacturing enables customized implant technology that are precisely redesigned to the individual anatomical structure. 

First, the relevant target region is precisely measured using computer tomography (CT) or magnetic resonance imaging (MRI). Subsequently, a computer-aided simulation and planning phase follows, taking into account movement sequences, stress and biological factors. In the next step, they are manufactured using 3D printing from materials such as titanium, ceramic or biocompatible polymers. 

These offer various advantages: 

• Accurate fit: Minimizes loosening or incorrect positioning 
• Operation time: Shorter because precise planning is available 
• Long-term stability: Thanks to physiological load distribution 
• Integration: Implant blends in better with the tissue 

Examples of applications are: 

• Cranioplasty: Individual cranial implants after accident or tumor  
• Dental implantology: Digital planning of implant posts with exact positioning in the jawbone 
• Spinal implants: Tailor-made systems for stabilization in cases of scoliosis or vertebral body replacement 
• Jaw implants: reconstruction of complex structures with exact restoration of chewing and speech function 
• Acetabular cups for hip prostheses: Patient-specific geometries for optimal force distribution 
• Orbital implants after eye loss: Cosmetically and functionally adapted implants for prosthesis positioning 

This patient-oriented approach not only provides more precise solutions but also reduces complications and clinical follow-up treatments. It also increases efficiency in the operating theater and promotes safety. 

The field is increasingly benefiting from technological support. Robots, navigation systems and high-resolution imaging ensure more precise treatment, fewer risks of complications and more efficient clinical processes. 

Robot-assisted systems, for example with DaVinci systems, enables surgeons to perform fine motor movements that would otherwise be difficult to implement. The robotic instruments are precisely controlled, reduce blood loss and lead to smaller incisions. In combination with intraoperative navigation based on CT/MRI data, precise orientation and implant placement is possible. A particular field of health innovation is the use of virtual reality (VR) for training surgical skills. VR technologies facilitate realistic training simulations that can be performed virtually without risk. 

The advantages are extensive: 

• Smaller wounds: Reduced incisions protect the surrounding tissue, resulting in less scarring. At the same time, the risk of post-operative infections is reduced as the entry surface for germs is minimized. 
• Shorter hospitalization: Patients can often leave the hospital after just a few days. The early return to familiar surroundings supports recovery and reduces the risk of nosocomial infections. 
• Better functional results: Thanks to precise technology, anatomical structures can be reconstructed exactly, enabling improved biomechanical function. This has a particularly positive effect on mobility and long-term resilience. 
• Increased safety: By using real-time imaging and digital assistance systems, surgical steps can be continuously monitored and adjusted. This increases accuracy and reduces the risk of unwanted deviations.

Medical technology is developing rapidly. New materials, networking and digital systems are fundamentally changing the way prostheses, surgical implants and procedures are handled. The following trends show where the industry is heading. 

The future of medical prostheses 

Prosthetic systems are evolving into multifunctional platforms that interact with digital environments. Using sensors to detect movement and actuators for targeted control, they will automatically adapt to the situation. They communicate with smartphones or smartwatches so that doctors can make remote diagnoses and adjustments. 

• Sensors detect muscle impulses, nitrogen content or humidity 
• Adaptive resistance systems that adjust to conditions in fractions of a second 
• Energy generation through movement to supply the electronics

Innovations in medical implants  

They are also increasingly focusing on integrated intelligence. Miniaturized sensors measure parameters such as temperature, pH value or mechanical stress. Data are transmitted wirelessly to external monitoring systems, allowing doctors to identify complications at an early stage. 

• Bioresorbable materials that dissolve after healing 
• Antibacterial coatings that prevent infections 
• Drug delivery, for example antibiotic release after medical procedure 

The aim is an integrated system of diagnosis, therapy and monitoring that increases patient safety. 

Technological advances in surgery 

There is a trend towards medicine robotics, artificial intelligence (AI) and augmented reality (AR) in this area. These enable improved preparation, execution and aftercare. 

Innovations: 

• OR simulation with virtual reality for training and complex case planning 
• Artificial intelligence-based decision-making aids that simulate surgical procedures and offer alternatives 
• Fully integrated robotic systems that automate repetitive tasks 

This technology can be used in telemedicine in particular: Remote surgical intervention or consultation by specialized surgeons is becoming increasingly realistic.
