Clinical application and advantages of intraoperative 3D navigation C-arm in spinal surgery

 The intraoperative 3D navigation C-arm not only brings a new clinical experience for physicians and improves surgical precision, but also generates "CT-like" tomographic images to assist in the intraoperative confirmation of surgical results, which can greatly shorten the patient's hospital stay and postoperative recovery period. Intraoperative 3D navigation C-arm is gradually becoming an indispensable tool in all kinds of spine surgery and even joint and trauma surgery.

Clinical case of intraoperative 3D navigation C-arm of Perlove Medical

 

Case 1

Patient: female, 73 years old

Procedure: thoracolumbar intervertebral fusion + laminar decompression + canal enlargement + spinal cord and nerve root adhesion release

 

Two years ago, the patient presented with numbness of the skin on the left side of the thoracic back with a feeling of banding, numbness of the skin on the left upper arm, denial of muscle weakness, and CT of the thoracic plain vertebrae showed: normal sequence of the thoracic vertebrae, existence of physiological curvature, osteophytes at the vertebral body edges, slight degeneration of the intervertebral disc, hyperplasia of the T7-T9 ligamentum flavum with ossification, compression of the endocapsular capsule, and spinal stenosis. Diagnostic imaging: ossification of the ligamentum flavum.

Preoperative images

Perlove Medical's intraoperative 3D navigation C-arm quickly generates cross-sectional, sagittal, coronal tomographic and 3D stereoscopic images to facilitate the surgeon's confirmation of the surgical site. the large flat panel of the C-arm provides an excellent display field to better visualize the global situation of the surgical site and ensure the accuracy of surgical planning and execution.

Case 2

Patient: female, 58 years old

Procedure: lumbosacral interbody fusion

 

The patient went to the hospital a month ago with bilateral lower extremity pain and was diagnosed with lumbar disc herniation. The patient went to the clinic on his own and was given tui-na traction, but the pain was not significantly relieved, and he went to the hospital for further treatment. Imaging diagnosis: L3-4 disc herniation with narrowing of the spinal canal (central type).

Preoperative images

Using the Perlove Medical intraoperative 3D navigation C-arm for fluoroscopy, we confirm the responsible intervertebral disc, plan the surgical plan according to the fluoroscopic image guidance, fully expose the bone tissue, and remove the lamina with specialized instruments to expose the nerve and spinal canal; under the guidance of the C-arm, we determine the position of the pedicle above and below the responsible intervertebral disc, formulate the needle entry point and needle entry direction, and implant spinal screws along the direction of the pedicle for The intervertebral fusion device was placed and the screws were reinforced. Finally, C-arm fluoroscopy is performed to confirm the completion of the procedure.

Intraoperative 3D imaging: An innovative clinical experience

 

Because of the complex anatomy and important physiological functions of the spine, surgery involves a high degree of risk and uncertainty, so intraoperative imaging has a direct impact on surgical expectations and outcomes. Perlove Medical's intraoperative 3D navigation C-arm allows for rapid switching between 2D and 3D imaging modes. It takes only 30 seconds to switch from 2D to "intraoperative CT" mode with one click, completing intraoperative 3D image acquisition and generating "CT-like" tomographic images simultaneously to achieve accurate positioning from multiple angles, improving surgical efficiency and enhancing surgical quality.

 

Large field of view More efficient

Perlove Medical's intraoperative 3D navigation C-arm adopts a 30CM*30CM dynamic flat panel detector with a large imaging range (5 lumbar vertebrae can be imaged at once), eliminating the need for repeated fluoroscopy and saving surgical time.
