How is a C-arm machine used when cementing bone?


Percutaneous kyphoplasty (PKP) is a common orthopedic procedure that allows patients with vertebral compression fractures to recover quickly. The procedure is vividly referred to as “cementing” because it is similar to “grouting concrete to reinforce the damaged area”.

Cementing is usually done with the help of a C-arm machine, how is it used? Here is a case study from the Second Affiliated Hospital of Nanjing Medical University.

The patient’s condition was lumbar compression fracture, and the doctor’s consultation adopted cement fixation under the C-arm machine. The principle is similar to the construction of the perfusion technology, using a puncture needle under fluoroscopy to accurately align the collapsed vertebral body in the middle and upper end, the bone cement will be injected into the fractured vertebrae, after solidification can play a supportive, fixed effect, so as to allow the fractured vertebrae to restore the stability of the fractured vertebrae, so that the pain will be reduced or disappeared and to prevent the fractured vertebral body from collapsing further.

PKP Surgical Record:

(1) The patient is in the prone position, and then use the characteristics of the PUAI large flatbed C-arm machine with flexible positioning to quickly locate the position of the pedicle root, determine the point of entry, the routine disinfection of the surgical scope laying aseptic towels, configuration of anesthetic in the localization of local anesthesia;.

(2) Intraoperative incision of 5 millimeters, with the help of high-definition images of large field of view flatbed C-arm machine PLX119C, to determine the direction of the needle and the depth of the needle. A tube was placed into the vertebral body via the pedicle to establish access, and a bone expander (balloon) was inserted. The balloon was expanded to restore the height of the vertebral body and create a cavity within the vertebral body, the injection dose of bone cement was determined, and the bone cement was injected to observe its spread.

(3) The injection process requires C-arm fluoroscopy to check the distribution of the bone cement and prevent the bone cement from exposing into the vertebral canal and causing nerve damage. After filling the bone cement in the vertebral body, the working sleeve was pulled out to stop bleeding, and the patient continued to lie in prone position for ten minutes, waiting for the bone cement to harden, and the operation was finally completed successfully.
