“…Various leading-edge puncture support devices have been developed. Xu HT et al proposed a navigation system that supported correct puncturing in PVP working with the C-arm tracker, patient tracker, and puncture needle tracker adjusting the spinal image information [ 28 ]. Wang B et al proposed a method for guiding punctures in Balloon kyphoplasty (BKP) using a system consisting of a reference tracker, a robotic arm, and a monitor [ 29 ].…”

Purpose To clarify the accuracy of vertebral puncture of the vertebral tertile area needling (VETERAN) method puncturing the pedicle superimposed on one-third of the width between the lateral vertebral line to the contralateral medial lamina line compared with Cathelin-needle-assisted puncture (CAP) method puncturing using the Cathelin needle as a guide in percutaneous vertebroplasty. Materials and methods 449 punctures by CAP method and 125 punctures by VETERAN method were enrolled. We compared the puncture accuracy of both methods. We estimated a vertebral estimated tilting ratio (VET-ratio) defined as ratio of the distance between the lateral vertebral line and the contralateral medial laminal line to the distance between the vertebral lateral line and the puncture point measured by computed tomography. We also estimated the procedural items and clinical outcomes. Results VETERAN method with 100% of punctures within safe zone (cortical breaches within 2 mm) had significantly higher accuracy than CAP method with 97.8% (p < 0.01) for the 2 mm incremental evaluation. No cases with a VET-ratio of 36% or less had cortical breaches. VETERAN method had shorter operative time per puncture (p < 0.01) and exposure time per puncture (p < 0.05). Conclusion VETERAN method reduced the occurrence of the inaccurate puncture, operative times, and exposure times. A VET-ratio with 36% or less is associated with a safe puncture using VETERAN method.

“…Neumann et al developed a robotic system that can be remotely controlled to inject bone cement, along with a cold passive exchanger that slows cement hardening [ 110 ]. A navigation system in which a C-arm tracker, patient tracker, and puncture-needle tracker coordinate spinal imaging information to assist in accurate punctures in PVP was described by Xu et al [ 111 ]. Wang et al proposed a method to guide the puncture in BKP that uses a system consisting of a reference tracker, robotic arm, and monitor [ 112 ].…”

Current status and challenges of percutaneous vertebroplasty (PVP)

A narrative review regarding percutaneous vertebroplasty (PVP) for osteoporotic vertebral fracture (OVF) is provided herein, addressing the epidemic of OVF in Japan, the latest response to the criticism of PVP for OVFs, the indications and potential risks of PVP for OVFs, and a future perspective for PVP. Each year in Japan, approximately 32,000 patients aged 55 years or older suffer from chronic low back pain for several months to several years due to a compression fracture. PVP is one of the surgical treatments for an OVF, and it is less invasive compared to the traditional open surgery. PVP is suitable for OVF patients who have difficulty walking as assessed by the modified Yokoyama’s activities of daily living (ADL) scoring system, and for patients with Kummell's disease diagnosed by CT and MRI examinations. Serious adverse events related to PVP occur in 1.1–3.3% of the cases, but direct deaths from PVP are extremely rare at less than 1%. Recent studies demonstrated that OVF patients treated with PVP are less likely to die after the treatment than non-surgically treated patients, which conflicts with the Cochran reviews’ conclusion not supporting PVP for OVFs. Novel robotic systems and procedure-support devices are being developed, providing a next step toward fully automated PVP procedures.

“…[ 4 ] Conventionally, computed tomography (CT) has been used to guide percutaneous cementoplasty. [ 5 ] However, cancer patients who undergo radiotherapy for primary tumors are concerned about radiation exposure associated with the procedure. Thus, navigation can be a good alternative for CT in guiding percutaneous cementoplasty.…”

Rationale: Percutaneous cementoplasty is a minimally invasive procedure that can provide immediate pain relief and improve range of motion in patients with metastatic bone pain. Conventionally, this procedure is guided by computed tomography (CT). However, to minimize exposure to radiation, we performed percutaneous cementoplasty under the guidance of a navigation system. Patient concerns: A 60-year-old man presented with left hip pain for several months due to bone metastasis in the left ilium. Diagnoses: The patient was diagnosed with lung cancer and multiple bone metastases including ileum. Interventions: The puncture needle was placed under the guidance of a navigation system with pre-procedure CT images, and bone cement was injected into the osteolytic lesion in the left ilium. Outcomes: Bone cement placement was confirmed by post-procedure radiography, and its distribution was satisfactory. The patient's Karnofsky Performance Scale and Brief Pain Inventory scores showed improvement in pain and mobility without complications. Lessons: Percutaneous cementoplasty guided by a navigation system is a safer and more effective method with less radiation compared with conventional CT-guided methods.
