“…The risk of adjacent vertebral fracture was estimated to be 9%, which is similar to (or slightly lower than) the rates reported in the literature for balloon kyphoplasty. We conclude that VBS can be considered a safe and effective surgical technique for the treatment of vertebral fractures and osteoporotic vertebral compression fractures with a low rate of adverse events (24)(25)(26)(27)(28).…”

“…By using ligamentotaxis, it is possible to produce a 'concrete reduction of the fracture', thus recovering the vertebral height and providing a cavity into which highly viscous poly (methylene methacrylate) (PMMA) can be injected (25,26). After the expansion phase, the balloon can be deflated and Extensive mechanical and biomechanical tests have been performed to characterize the mechanical behavior and performance of the VBS (25)(26)(27)(28). The preclinical testing of the VBS was designed to evaluate all relevant loading conditions to demonstrate a reasonable assurance of safety.…”

Purpose Recently, a new minimally invasive technique called 'vertebral body stenting' (VBS) was introduced for the treatment of osteoporotic vertebral fractures. The technique was developed to prevent the loss of reduction after deflation of the balloon and to reduce the complication rate associated with cement leakage. Methods The amount of kyphosis correction, improvement of vertebral body height and quantitative cement leakage rate by applying CT-based quantitative volumetry after VBS were measured in 27 patients (55 vertebra) and compared with a control group (29 patients, 61 vertebrae), which was treated with conventional vertebroplasty. Results After VBS, a significant improvement was seen in vertebral height, compared to conventional vertebroplasty. The mean improvement in segmental kyphosis and vertebral kyphosis were 5.8°(p \ 0.05) and 3.5°( p \ 0.05), respectively. In the VBS group, the mean injected volume of cement per vertebral body was 7.33 cm 3 (3.34-10.19 cm 3 ). The average amount of cement outside the vertebrae was 0.28 cm 3 (0.01-1.64 cm 3 ), which was 1.36 % of the applied total cement volume. In the vertebroplasty group, the applied mean volume of the cement per level was 2.7 cm 3 (1-5.8 cm 3) and the average amount of cement outside the vertebrae was 0.15 cm 3 (0.01-1.8 cm 3 ), which was 11.5 % (0.2-60 %) of the applied total volume of cement. Conclusion The frequency of cement leakage after VBS was 25.5 % compared to 42.1 % in the vertebroplasty group. VBS led to a significant decrease in the leakage rate compared with conventional vertebroplasty.

“…Other studies show a variable degree of correction of kyphotic deformity between 1.7° and 6.6° for vertebroplasty, 4.8° and 9.9° for BKP, and 5.6° and 7.3° for VBS. 3,9,13,18,22,29 Deflation of the balloon results in a loss of 25% of vertebral body height. 24 Voggenreiter et al 30 described a spontaneous mean reduction of VCF of 6.5° due to placement of the patient prone only.…”

“…In contrast to BKP, VBS applies expandable stents in addition to balloons to prevent height loss after the deflation of the balloons. 9,18,30 Although both latter techniques are effective in terms of pain relief and partial correction of the kyphotic deformity, their high product cost limits their distribution. 9,14,15 In 2006, Orler et al introduced an alternative surgical approach called lordoplasty.…”

OBJECTIVE Vertebroplasty and balloon kyphoplasty are effective treatment options for osteoporotic vertebral compression fractures but are limited in correction of kyphotic deformity. Lordoplasty has been reported as an alternative, cost-effective, minimally invasive, percutaneous cement augmentation technique with good restoration of vertebral body height and alignment. The authors report on its clinical and radiological midterm results. METHODS A retrospective review was conducted of patients treated with lordoplasty from 2002 to 2014. Inclusion criteria were clinical and radiological follow-up evaluations longer than 24 months. Radiographs were accessed regarding initial correction and progressive loss of reduction. Complications and reoperations were recorded. Actual pain level, pain relief immediately after surgery, autonomy, and subjective impression of improvement of posture were assessed by questionnaire. RESULTS Sixty-five patients (46 women, 19 men, age range 38.9–86.2 years old) were treated with lordoplasty for 69 vertebral compression and insufficiency fractures. A significant correction of the vertebral kyphotic angle (mean 13°) and segmental kyphotic angle (mean 11°) over a mean follow-up of 33 months (range 24–108 months) was achieved (p < 0.001). On average, pain was relieved to 90% of the initial pain level. In 24% of the 65 patients a second spinal intervention was necessary: 16 distant (24.6%) and 7 adjacent (10.8%) new osteoporotic fractures, 4 instrumented stabilizations (6.2%), 1 new adjacent traumatic fracture (1.5%), and 1 distant microsurgical decompression (1.5%). Cement leakage occurred in 10.4% but was only symptomatic in 1 case. CONCLUSIONS Lordoplasty appeared safe and effective in midterm pain alleviation and restoration of kyphotic deformity in osteoporotic compression and insufficiency fractures. The outcomes of lordoplasty are consistent with other augmentation techniques.
