On August 7, the good medical training camp invited well-known experts in the field of orthopedics – Shanghai Jiao Tong University School of Medicine Affiliated Ninth People’s Hospital Professor Zhao Jie lumbar posterior intervertebral fusion technology in-depth explanations and guidance operation, through the standardization of (nail placement, decompression range, intervertebral fusion preparation) operation process, refinement of the technology, improve the treatment effect It helps doctors to learn the knowledge and surgical operation skills of lumbar posterior interbody fusion technology systematically and efficiently in the shortest time.

Perlove Medical’s large flat-paneled integrated C-arm assists in surgical practice.

Lumbar Interbody Fusion (LIF) is a traditional procedure for the treatment of lumbar spinal instability, in which two or more vertebrae are connected or fused together. It is mainly applied to vertebral destructive disease, spinal instability, prevention or correction of deformity, etc. It has been successfully applied to relieve low back pain, rebuild spinal stability, restore the normal sequence of the spine, etc. It is one of the most important surgical procedures in spine surgery for treating serious lumbar spine diseases.

Posterior lumbar interbody fusion (PLIF) is one of these procedures. It is performed through an incision in the back of the body to expose the spine. The intervertebral discs are removed, an interbody fusion device is used to maintain proper disc height, and a bone graft is used to promote fusion of the adjacent vertebrae to maintain spinal stability.

Surgical Procedure

The incision and field are revealed and an incision of approximately 8-10 centimeters is made in the back of the waist. A Perlove Medical large flatbed C-arm is used to precisely position the spine for surgery.

The skin and subcutaneous tissues are incised and the paraspinal muscles are peeled back to fully visualize the upper and lower vertebral segments, and laterally to fully visualize the transverse processes, which are held open with a deep autopropagator and compressed to stop the bleeding and create space for the surgery.

The pedicle (plate) is carefully removed so that the nerve root can be visualized and accessed. The small joints above the nerve root may be trimmed to allow more room for the nerve root. The surgeon then removes the affected disc and its surrounding tissue and makes some preparations for vertebral fusion on the surfaces of the adjacent vertebrae.

Between the adjacent vertebrae, a structural support cage (interbody fusion device) made of titanium, carbon fiber material interbody fusion, or polymer material is implanted to maintain the height of the vertebral space. The interbody fusion removes pressure from the compressed nerve root and preserves the proper interbody space height to provide stability to the spine and support normal loads. Interbody fusion devices are often filled with autogenous bone, or allograft bone…to promote bone regeneration and permanently fuse the vertebrae together.

Screw implantation of the pedicle nail: The cortex is bitten off at the entry point with a bone biting forceps, the screw entry point and orifice are prepared with a cotter, and the locator pin is inserted.

C-arm fluoroscopy was used to confirm the accuracy of the screws and the standard screws were implanted. The rest of the screws were implanted in the same way. C-arm fluoroscopy is used again to confirm the screw position and length. Insert the desired length and bend of the nail rod with the rod holder. The nut is tightened temporarily, with a spreading forceps and rod presser to create spreading and compression between the collets, and then finally tightened to avoid any loosening and wobbling.

The instruments are removed, the incision closed and bandaged to complete the procedure.

The Perlove Medical Large flat panel All-in-One C-Arm utilizes a 30CM x 30CM flat panel detector, which can generally image 5 lumbar vertebrae at one time, presenting a wider field of view. It enables the doctor to observe the vertebral body fluoroscopy comprehensively at one time, making the surgery more efficient and precise.
