How can 3D mobile flat panel C-arm assist PVP surgery to effectively reduce cement leakage ?


The Perlove Medical 3D flat panel mobile C-arm is able to provide high-definition orthopedic 3D images in the operating room. After completing the vertebroplasty, the surgeon can not see the leakage of bone cement on the 2D front and side images, but through the 3D flat panel mobile C-arm image, the surgeon can observe how the bone cement is dispersed in the vertebral body in 360°.

Osteoporotic vertebral compression fractures (OVCF) are mostly seen in the elderly, mainly manifested by pain in the lower back or chest. Due to osteoporosis, the strength and stiffness of the vertebrae are poor, which can easily lead to fracture, and patients with OVCF have difficulties in daily activities, poor health status and low quality of life.

Traditional treatments include medication, physiotherapy, bed rest and other conservative treatments. Although the symptoms can be partially relieved, prolonged bed rest will accelerate bone loss and muscle atrophy at the same time, which is not conducive to the recovery of the disease, and will also bring great psychological and economic pressure to the patients and reduce their quality of life.

Percutaneous vertebroplasty (PVP) is the main surgical treatment for OVCF. With the help of imaging equipment (e.g., 3D mobile flat panel C-arm), osteoplastic materials (e.g., bone cement) are injected into the vertebral body from outside of the body via a puncture needle to restore the height of the vertebral body.

Bone Cement Infusion

Bone cement infusion can enhance the strength and stiffness of the vertebral body, so it is commonly used to improve the condition of the vertebral body during the operation.PVP surgery can quickly relieve the pain of the patient, shorten the hospitalization time, and improve the quality of life by resuming daily activities as soon as possible.

A common and serious complication of PVP surgery is cement leakage, which can lead to paralysis or death in severe cases. The main factors affecting leakage are: case condition, operation technique, surgical instruments, bone cement material, and imaging equipment.

Among them, the case situation and operation skills can be solved through the gatekeeping of surgical indications, standardized training and strict access system; while the surgical instruments, bone cement materials and imaging equipment must be realized through the relevant medical devices, consumables and equipment manufacturers through iterative new technology.

Ordinary orthopedic C-arm machines only provide coronal and sagittal images. Confirmation of the actual spatial situation also requires rich surgical experience as support, and requires repeated puncture several times to complete, so it is easy to damage the inner wall of the pedicle, resulting in cement leakage outside the vertebral body, and in serious cases, it will enter the spinal canal.

3D mobile flat panel C-arm image

The 3D mobile flat panel C-arm can assist clinicians in choosing the appropriate angle and position of the needle through the three tomographic images of coronal, sagittal, and transverse sections, as well as the 3D reconstructed three-dimensional spatial images, avoiding multiple puncture, effectively reducing the leakage of the bone cement, and improving the safety.

Perlove Medical 3D mobile flat panel C-arm can provide 2D/3D image data during orthopedic surgery, with extremely low radiation dose, which is 1/30-1/40 radiation dose of traditional CT. Adopting 30CM*30CM dynamic flat panel detector, the imaging range is large (5 lumbar vertebrae can be imaged at one time), which eliminates the need for repeated fluoroscopy and saves surgical time, thus improving surgical efficiency and surgical effect.
