“…The needle was inserted through the cortex by tapping its back end with a hammer. 5 If the end of the needle reached the inside boundary of the ipsilateral pedicle in the anteroposterior view, the lateral view should be checked to see whether the end of the needle did not compromise the spinal canal, and safely arrived inside the vertebral body.…”

“…When the needle tip reached the cortex of the left transverse process, it overstrode the superior margin of the transverse process and went forward scratching the superolateral cortex of the pedicle. 5 The needle tip could be located at the superolateral junction between the pedicle and vertebral body. After penetrating the cortex, minor adjustments might be required as the needle was directed to the target point.…”

“…But recently a unipedicular approach has been advocated, reducing the operating time, radiation exposure, and complications, and increasing the cost-effectiveness of the procedure (11,12). An increasing number of studies have been conducted to apply unilateral balloon kyphoplasty in the treatment of OVCFs (13)(14)(15)(16)(17)(18)(19). Scholars have compared the clinical and radiological results of unilateral and bilateral kyphoplasty approach (20)(21)(22)(23)(24)(25)(26)(27)(28).…”

The Role of Unilateral Balloon Kyphoplasty for the Treatment of Patients with OVCFS: A Systematic Review and Meta-Analysis

Background: An increasing number of studies have been conducted to apply unilateral balloon kyphoplasty in the treatment of ostroporotic vertebral compression fractures (OVCFs). However, the efficacy and safety of unilateral kyphoplasty and whether a unilateral or a bilateral approach is superior is controversial. Objectives: The purpose of this study was to evaluate the role of unilateral balloon kyphoplasty and use meta-analysis to compare the efficacy and safety of unilateral and bilateral kyphoplasty in patients with OVCFs. Study Design: A systematic literature search was conducted from 1970 to April 2017 using Medline database and the Cochrane Central Register of Controlled Trials. Articles were limited to those published in English. Randomized controlled trials and nonrandomized comparative studies were also included. Setting: The following search terms were used: “osteoporotic vertebral compression fractures,” or “OVCF,” and “unilateral kyphoplasty,” or “unipedicular approach,” or “single balloon kyphoplasty,” or “one balloon kyphoplasty.” A comprehensive search of reference lists of retrieved articles and previous published reviews was also performed to ensure inclusion of all possible studies. Methods: All potential articles were independently reviewed by 2 investigators for inclusion into the final analysis. MINORS score was used for nonrandomized studies, and Detsky quality index was applied for prospective randomized controlled trials. Systematic review and meta-analysis was performed for the included studies. Results: After unilateral balloon kyphoplasty the mean postoperative visual analog score (VAS) was from 1.74 to 4.77, mean postoperative kyphotic angle was from 5.9º to 11.22º, and complications involving cement leaks was from 6.8 to 21.9% or adjacent level fractures was from 0 to 5.6%). Unilateral kyphoplasty had significantly lower operative time, and less bone cement volume; however, the postoperative VAS, Oswestry Disability Index (ODI), vertebral height restoration rate, and cement leakage and adjacent vertebral fracture rate, were similar to bilateral kyphoplasty. Limitations: Only 6 randomized controlled trials and 3 retrospective comparative studies were selected for analysis. Heterogeneity was detected among the studies when we pooled the outcomes. Conclusions: Based on the available evidence, the clinical and radiological results of unilateral balloon kyphoplasty were as good as those of bilateral balloon kyphoplasty for the treatment of OVCFs. And unilateral kyphoplasty had advantages in terms of operation time, radiation exposure, and cost. Key words: Unilateral balloon kyphoplasty, bilateral balloon kyphoplasty, osteoporotic vertebral compression fractures, complications of balloon kyphoplasty, meta-analysis

“…The current standard technique for VP involves bipedicular cannulation, but other authors recommend that the unilateral VP can also achieve the same clinical results. 8 Theoretically, unilateral VP can reduce the operating time, surgery-associated complications, radiation exposure, and cost. The aim of this study was to evaluate and compare the clinical outcomes and cement leakage of unilateral versus bilateral approach.…”

Unilateral Extrapedicular Vertebroplasty and Kyphoplasty in Lumbar Compression Fractures : Technique, Anatomy and Preliminary Results

Abstract: The method of a unilateral extrapedicular approach in kyphoplasty and vertebroplasty in the lumbar area might be similar to that in thoracic approach using a route via the extrapedicular space. However, different anatomical characteristics of the lumbar area should be considered.
