FAQ

What is the application of minimally invasive orthopedic surgical instruments in fracture repair surgery?

The application of minimally invasive orthopedic surgical instruments in fracture repair surgery is mainly reflected in the following aspects:

Percutaneous reduction and internal fixation: This is a common method in minimally invasive technology. The fracture ends are reduced through a small incision, and the fracture site is fixed with internal fixation devices such as screws and steel plates to promote healing. This method has the advantages of less trauma and faster recovery.

Arthroscopically assisted reduction: In recent years, with the development of arthroscopic technology, subtalar arthroscopy has gradually been used in the treatment of calcaneal fractures. This method can fully observe the subtalar articular surface, making percutaneous or small incision reduction and internal fixation easier, while reducing the incidence of wound and joint complications.

External fixator: For critically ill patients with severe multiple fractures or comminuted fractures combined with multiple trauma, damage control surgery using external fixators to repair orthopedic trauma has been gradually carried out in clinical practice. This method can reduce the mortality rate of early definitive surgical treatment.

Orthopedic surgical robots: such as TiRobot and Honghu Orthopedic Surgical Robots. These devices can assist doctors in developing personalized prosthesis implantation plans based on the patient's preoperative CT scan data and prosthesis model data, and provide precise positioning during surgery to improve the accuracy and safety of surgery.

3D printing technology: 3D printing technology can be used to design and make surgical guides, which can guide surgeons to perform precise cutting and drilling, thereby improving surgical accuracy, shortening surgical time, and reducing the risk of complications.

PIEZOSURGERY® Ultrasonic Micro-Vibration Technology: This device uses ultrasonic micro-vibration technology to achieve precise cutting and minimally invasive treatment, which can reduce soft tissue damage, promote healing, and reduce the risk of bone necrosis, thereby improving surgical results and patient satisfaction.

Laser Intelligent Bone Drilling: Laser drilling is a non-contact processing method with greater advantages. It avoids the damage of traditional mechanical drilling to the microscopic tissue structure of the bone hole, thereby improving postoperative healing.

In short, the application of minimally invasive orthopedic surgical instruments in fracture repair surgery not only improves the accuracy and safety of surgery, but also significantly reduces the patient's postoperative recovery time and complication rate, bringing patients a better medical experience.

What are the specific operating steps and technical points of percutaneous reduction and internal fixation in fracture repair?

The specific operating steps and technical points of percutaneous reduction and internal fixation in fracture repair are as follows:

Operation steps
Preoperative preparation:

General anesthesia or local anesthesia, choose the appropriate anesthesia method according to the patient's condition.

Perform detailed imaging examinations (such as X-rays, CT, etc.) on the patient to determine the type and location of the fracture.

Incision and exposure:

Choose an appropriate incision location. For example, in humeral surgical neck fractures, a longitudinal incision of about 4 cm is usually made along the fracture end.

Incise the skin, subcutaneous tissue and deep fascia to expose the fracture ends.

Reduction:

Use reduction forceps, towel clamps or skin clamps to fix the two ends, and reduce them according to the violent direction of the fracture through longitudinal traction.

In some cases, multiple adjustments may be required to ensure the best reduction effect.
Internal fixation placement:

Internal fixation (such as elastic intramedullary nails, screws, etc.) is percutaneously inserted into the corresponding bone structure. For example, in the case of surgical neck fracture of the humerus, the elastic intramedullary nail is first percutaneously inserted into the medullary cavity so that the nail tip is close to the fracture end.
In the treatment of spinal fractures, the use of minimally invasive percutaneous pedicle screw internal fixation technology can effectively correct the scoliosis of the spine and restore the normal sagittal shape of the spine through precise fixation and reduction.
Fixation and suturing:

After ensuring that the internal fixation is stable, the incision is sutured and bandaged.
Use C-arm fluoroscopy equipment to confirm the fixation effect to ensure that there is no displacement and further damage.
Technical points
Good fracture end reduction:

Good fracture end reduction is the key to success. In some complex fractures, secondary reduction may be required to achieve the best reduction effect.
Application of minimally invasive technology:

Minimally invasive percutaneous technology has the advantages of less trauma, less bleeding, and faster recovery, and is suitable for various types of fracture repair.
Application of navigation module:

Application of navigation module can simplify the surgical process, reduce the room for error, and improve surgical accuracy and efficiency.
Postoperative rehabilitation training:

Targeted rehabilitation training can be started early after surgery, including strengthening muscle strength, expanding joint range of motion, etc., so as to gradually improve motor function and improve the patient's daily living ability.
Complication prevention:

Pay attention to possible complications after surgery, such as infection, bleeding, etc., and deal with them in time.

How to evaluate the accuracy and safety of arthroscopically assisted reduction?

The accuracy and safety of arthroscopically assisted reduction can be evaluated by the following aspects:

Accuracy:

Arthroscopically assisted reduction technology can increase the accuracy of articular surface reduction. For example, in a study of wrist arthroscopy-assisted open reduction and internal fixation for the treatment of intra-articular fractures of the distal radius, the results showed that this method can clearly diagnose whether the TFCC is damaged, and the wrist function was improved after surgery.
Direct arthroscopic visualization is more accurate than fluoroscopy in evaluating joint steps or gaps.
Arthroscopic reconfirmation of reduction can enable accurate treatment, especially in intra-articular fracture surgery, where the anatomical reduction surface of the joint is initially obtained under fluoroscopy, which is usually difficult to accurately evaluate.
Safety:

Although arthroscopic surgery is a minimally invasive surgery, various complications are inevitable. However, through the analysis of public cases, the overall incidence and severity of arthroscopic complications are relatively low.
In the study of wrist arthroscopy-assisted open reduction and internal fixation for the treatment of distal radial intra-articular fractures, no complications such as screw loosening or breakage, vascular and nerve damage, incision infection, and traumatic arthritis occurred after surgery.
Minimally invasive technology, arthroscopic-assisted reduction technology, and intraoperative three-dimensional fluoroscopy technology will greatly improve the accuracy of fracture reduction and intraoperative damage to soft tissue.

What are the advantages of external fixators in the treatment of severe multiple fractures compared with traditional surgery?

The effect of external fixators in the treatment of severe multiple fractures has the following advantages over traditional surgery:

Good stability: The external fixator can provide good stability, making the fracture end difficult to displace, which is conducive to fracture healing.

Avoid damage to soft tissue: The external fixator can avoid damage to the soft tissue at the fracture end, especially the periosteum, thereby effectively preventing the lack of blood circulation at the fracture end, which leads to slow bone growth, nonunion or osteonecrosis in the later stage.

Less trauma: The installation of the external fixator is less traumatic and is suitable for closed reduction and external fixation of some fractures, especially in emergency patients. When internal fixation treatment cannot be used in time, the external fixator is an effective choice.

Easy to install: The installation process of the external fixator is relatively simple and easy to implement quickly, especially in emergency situations, it can quickly stabilize the patient's condition.

Stage treatment: For patients with severe multiple injuries and closed long bone fractures of the limbs, the external fixator can be treated in stages, and the treatment plan can be gradually adjusted and optimized to achieve the best effect.

External fixators have significant advantages over traditional surgery in the treatment of severe multiple fractures, including better stability, protection of soft tissues, less trauma, convenience of installation, and the possibility of staged treatment.

The latest progress and application prospects of 3D printing technology in minimally invasive orthopedic surgery.
The latest progress and application prospects of 3D printing technology in minimally invasive orthopedic surgery are very extensive and promising. The following is a detailed analysis based on existing data:

Latest progress
3D printing technology extracts CT and MRI data of patients, reconstructs three-dimensional anatomical structures, and obtains a solid fracture model. The three-dimensional structure it provides is clearer and more intuitive, helping physicians to fully understand the disease and formulate more reasonable surgical plans. For example, Shanghai Tongji Hospital introduced 3D printing guide technology, which achieves minimally invasive surgery through precise preoperative planning.

The orthopedic team of Peking University Third Hospital successfully completed the first implantation of a biomechanically adapted prosthesis, which matches the bone strength of patients with bone loss, improving the success rate and safety of the operation.

The Department of Orthopedics of the County Hospital used 3D printing technology to assist in the treatment of a patient with complex elbow triad. The patient is currently in good condition, which marks the successful application of this technology in county hospitals.

Combined with augmented reality (AR) technology, doctors can observe the location, size, and depth of the tumor through AR glasses, avoid important blood vessels, nerves, and tissues, making the operation safer and more accurate.

Application prospects
As the concept of minimally invasive surgery has become popular, computer-assisted technologies such as 3D printing, navigation and positioning systems, and orthopedic surgical robots have developed rapidly, greatly improving the accuracy and safety of surgery.

3D printing technology can customize personalized built-ins according to the specific situation of each patient, meeting the needs of the patient as much as possible, making the operation more accurate. This type of personalized implant has been used in laparoscopic pelvic fracture surgery and is particularly important when fixed in a narrow surgical field of view.

3D printing technology is not only used in clinical surgery, but is also widely used in medical education and demonstration. For example, the Ninth People's Hospital of Shanghai Jiaotong University School of Medicine uses rapid prototyping (RPM) technology to customize prostheses for pelvic floor reconstruction after pelvic floor reconstruction and hip repair for severe hip joint defects.

Although organ printing still has a long way to go, 3D printing has shown promise in fields such as tissue engineering and regenerative medicine, and progress in cell printing, bioprinting and innovative printing materials is also worth looking forward to.
