FAQ

What is the application of minimally invasive orthopedic surgical instruments in bone tumor surgery?

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

Robot-assisted surgery: In recent years, robot-assisted sacral tumor resection surgery has gradually been carried out. For example, the First Affiliated Hospital of Sun Yat-sen University uses minimally invasive ultrasonic bone knife for robot-assisted sacral tumor resection to improve surgical results and reduce trauma.

Microwave ablation technology: The Department of Orthopedics of the Second Hospital of Lanzhou University uses microwave ablation technology to treat bone tumors. This technology can be used as an independent percutaneous minimally invasive treatment method or auxiliary treatment method for hemostasis, tumor inactivation or tumor resection boundaries of some benign bone tumors and bone metastases.

Thermal ablation therapy: Including radiofrequency ablation (RFA), microwave ablation (MWA), high-intensity focused ultrasound ablation (HIFUA) and laser ablation, it is one of the main minimally invasive treatment methods for bone tumors.

Minimally invasive resection under precise navigation: Traditional bone tumor surgery is more traumatic, but modern surgery is developing in the direction of precision and minimally invasiveness. For example, the bone tumor team of Zhejiang Second Hospital uses precise intraoperative navigation to perform minimally invasive resection of bone tumors.

3D printing technology: Combined with 3D printing technology, clinicians can use navigation template technology to accurately remove tumors and customize 3D printed prostheses to ensure complete functional reconstruction.

Visual lens technology: Orthopedic experts from the Pediatric Trauma Orthopedics Center and the Sports Medicine Center of Wuhan Fourth Hospital use visual lens technology to open a small hole on both sides of the patient's heel, and use minimally invasive surgery under the visual lens to successfully remove the calcaneal tumor lesions.

The application of these minimally invasive orthopedic surgical instruments and technologies has significantly improved the accuracy and safety of bone tumor surgery, reduced the trauma and recovery time of patients, and helped patients achieve better rehabilitation effects.

What are the specific operating procedures and technical points of minimally invasive orthopedic surgical instruments in sacral tumor resection?

The specific operating procedures and technical points of minimally invasive orthopedic surgical instruments in sacral tumor resection are as follows:

Preoperative preparation:

The multidisciplinary diagnosis and treatment team (MDT) discusses and decides on the surgical plan, including whether to use robot assistance.

Assess the patient's condition and tumor location, and determine the surgical path and method.
Surgical steps:

Posterior total sacrum + left iliac crest resection: Tianji robot navigation is used to accurately cut the bone and remove the tumor. During this process, it is necessary to pay attention to reducing the risk of major bleeding.
Da Vinci robot-assisted: Use the Da Vinci robot to separate the presacral tumor and ligate the blood vessels supplying the tumor to reduce intraoperative bleeding.
Ultrasonic bone knife application: Use ultrasonic bone knife to perform osteotomy, completely separate the tumor, and allow the tumor to be completely removed.
Technical points:

Robot-assisted technology: Improve the accuracy of tumor resection in complex anatomical parts such as sacrum and pelvis, and reduce intraoperative bleeding and injury.
Abdominal aorta balloon temporary occlusion technology: Used to control intraoperative bleeding and further reduce the risk of minimally invasive surgery.
Frozen pathology examination: Frozen pathology examination is performed during the operation to ensure accurate judgment of the nature of the tumor and avoid misdiagnosis.
Postoperative treatment:

The patient is transferred to the orthopedic operating room under the supervision of the anesthesiologist, and the surgeon completes the subsequent surgical steps.
Rapid recovery after surgery, short hospitalization time, and stable patient indicators.

What are the comparative studies on the effects of microwave ablation technology in the treatment of benign bone tumors and bone metastases?

The comparative studies on the effects of microwave ablation technology in the treatment of benign bone tumors and bone metastases are mainly focused on the following aspects:

Microwave ablation combined with lesion curettage:

In the treatment of long bone metastases, microwave ablation combined with lesion curettage shows good safety and effectiveness. For example, Beijing Jishuitan Hospital studied this treatment regimen on 38 patients with long bone metastases of the limbs. The results showed that this method can effectively eliminate tumor cells, reduce surgical trauma, and improve the quality of life of patients.
Similarly, the First Affiliated Hospital of Nanjing Medical University conducted a study on 42 patients with bone metastases. The patients were divided into a microwave ablation combined with 3D printing technology lesion curettage + bone cement filling group (observation group) and a simple lesion curettage + bone cement filling group (control group). The results showed that microwave ablation combined with 3D printing technology has significant advantages in pain relief and quality of life improvement.
Microwave ablation combined with curettage:

Microwave ablation combined with curettage also shows significant efficacy and good safety in the treatment of pelvic bone metastasis. This technology can effectively eliminate tumor cells, reduce surgical trauma, and improve the quality of life of patients by combining microwave ablation and curettage.

Another study further verified the advantages of this method in pain relief and clinical efficacy by conducting a single-center retrospective analysis of patients with pelvic metastases who received microwave ablation combined with curettage.

In situ microwave ablation + internal fixation:

In the treatment of benign bone tumors, in situ microwave ablation + internal fixation is used to compare the effect of radical tumor resection + tumor-type prosthesis reconstruction. Postoperative gait data was collected by infrared light navigation technology, and the recovery of knee joint movement function within two years after surgery was compared. The results showed that in situ microwave ablation + internal fixation has certain advantages in recovery of movement function.

Other related studies:

A study using percutaneous microwave ablation to treat bone tumors showed that 47 patients had significant pain relief and improved quality of life after initial treatment.
The short-term and long-term efficacy of 125I radioactive particle implantation combined with in situ microwave inactivation for pelvic metastatic tumors was also discussed. Although it is mainly aimed at bone metastasis, it provides another possible combination of microwave ablation in tumor treatment.
Microwave ablation technology has shown significant efficacy and good safety in the treatment of bone metastasis, especially when combined with lesion curettage and 3D printing technology. In the treatment of benign bone tumors, in situ microwave ablation + internal fixation also shows certain advantages in the recovery of motor function.

What are the advantages and disadvantages of radiofrequency ablation (RFA), microwave ablation (MWA), high-intensity focused ultrasound ablation (HIFUA) and laser ablation in the treatment of bone tumors?

In the treatment of bone tumors, radiofrequency ablation (RFA), microwave ablation (MWA), high-intensity focused ultrasound ablation (HIFUA) and laser ablation each have their own advantages and disadvantages. The following is an analysis based on the results:

Radiofrequency ablation (RFA):
Advantages: It is pointed out that radiofrequency ablation is a new minimally invasive treatment technology for solid bone tumors that has emerged in recent years. It has the advantages of good effect, less trauma, low cost, fast recovery, low risk, and repeatability. It is further explained that radiofrequency ablation is suitable for small benign intrabone tumors (such as osteoid osteoma, hemangioma) and metastatic malignant bone tumors (especially tumors of the spine and pelvis). The main purpose is to control the local spread of tumors and effectively relieve the pain caused by tumors.
Disadvantages: The results do not clearly mention the disadvantages of radiofrequency ablation, but it can be speculated that compared with more advanced technologies, it may have limitations in some aspects such as accuracy or long-term effects.
Microwave ablation (MWA):
Advantages: It is pointed out that microwave ablation has become an important means of limb-preserving treatment of bone tumors due to its many advantages such as repeatability, real-time image guidance, less trauma, short operation time and low operation cost. It is also mentioned that microwave ablation technology is used for intractable bone cancer pain, with an efficiency of up to 96%, and has the effects of tumor removal, tumor reduction and pain relief.
Disadvantages: The results do not explicitly mention the disadvantages of microwave ablation, but it can be inferred that it may have limitations in some aspects such as equipment cost or operation complexity compared with more advanced technologies.
High-intensity focused ultrasound ablation (HIFUA):
Advantages: It is pointed out that the long-term follow-up effect of HIFU treatment for primary bone malignancies is significant, with a 5-year survival rate of 50.5%. HIFU treatment has no radioactive radiation, no bone marrow suppression, and the number of treatment courses is determined according to the size, location and treatment effect of the tumor. Usually, a 3-5cm mass can be controlled in one course.
Disadvantages: The results do not explicitly mention the disadvantages of HIFU, but it can be inferred that it may have limitations in some aspects such as treatment range or depth compared with more advanced technologies.
Laser ablation:
The results do not provide specific information about laser ablation, so its advantages and disadvantages cannot be directly derived from the results.
