Balloon kyphoplasty versus percutaneous vertebroplasty for osteoporotic vertebral body compression fractures: clinical and radiological outcomes

BACKGROUND CONTEXTOsteoporotic vertebral body compression fracture are the commonest fractures amongst the other osteoporotic fracture sites. These fragility fractures are the result of low energy mechanical forces that that would not ordinarily result in fracture. Percutaneous vertebroplasty and balloon kyphoplasty has been widely used as minimally invasive procedures to treat painful vertebral compression fractures.PURPOSEAim of the present study was to evaluate radiological, clinical and functional outcome of patients with osteoporotic vertebral body fractures treated with Balloon Kyphoplasty and Vertebroplasty.STUDY DESIGNProspective cohort studyPATIENT SAMPLE40 patients (Male:15, Female: 25) with average age of 56 +/- 8 years diagnosed with osteoporotic vertebral body compression fracture on clinical and radiological evaluation with no neurological deficit and no other associated fractures were included.OUTCOME MEASURESOperative time, cost for the procedure, gain in vertebral body height, reduction in pain, ability to perform daily routine activities, risk of cement leakage and any other systemic complications were evaluated and compared in both the study groups.METHODSAll the patients underwent conventional Xray, MRI (to rule out acute from chronic fracture, to check compromise of spinal canal and calculate collapse in vertebral body height), Visual analog scaling for severity of pain and difficulty in daily routine activities by Oswestry disability index preoperatively. Post operative clinal, functional, radiological outcome and complications were compared in patients treated with percutaneous vertebroplasty and balloon kyphoplasty.RESULTThere was significant difference in intraoperative time period and procedure cost for the patients treated with Vertebroplasty(50.75min, 25k) in comparison to balloon kyphoplasty (71.95, 50k) with p value being < .001There was significant difference between preoperative and postoperative study parameters in both the study groups but there was no significant difference in post operative study parameters amongst both the study groups with p values >.05 for different parameters, 0.381(Gain in vertebral height), 0.108 (pain relief), 0.846(Oswestry disability index) and 0.197(risk of cement leakage)CONCLUSIONOur study suggested that percutaneous vertebroplasty requires less operative time and is more economical than balloon kyphoplasty. Increase in intraoperative time increases the risk of infection. Though the cases of Intraoperative operative cement leakage were more in percutaneous vertebroplasty but is was not significant. However the final radiological, clinical, functional outcome and overall complications were found to be similar in both the groups. Balloon kyphoplasty provided no added benefit over percutaneous vertebroplasty. A study with larger sample size will be needed to warrant one surgical procedure superior to other in the treatment of osteoporotic vertebral body compression fracture.

Comparative analysis of clinical outcomes in patients with osteoporotic vertebral compression fractures (OVCFs): conservative treatment versus balloon kyphoplasty

Background context

Most osteoporotic vertebral compression fractures (OVCFs) can be treated conservatively. Recently, kyphoplasty has become a common treatment for painful osteoporotic compression fractures and has shown numerous benefits, such as early pain control and height restoration of the collapsed vertebral body. In spite of being a simple procedure, numerous complications related to kyphoplasty have been reported. Moreover, there is limited evidence to support its superiority.

Purpose

To compare the clinical outcomes of patients with OVCF according to different treatment modalities and identify clinical risk factors related to failure of conservative treatment of OVCF.

Study design

A prospective study consisting of a review of case report forms.

Patients sample

We prospectively enrolled 259 patients who had one or two acute painful OVCFs confirmed by magnetic resonance imaging. All patients were treated conservatively in the initial 3 weeks. Kyphoplasty was performed in 91 patients who complained of sustained back pain and disability in spite of conservative treatment for the initial 3 weeks.

Outcome measures

Pain score using visual analog scale (VAS) and the Oswestry Disability Index (ODI).

Methods

Participants were stratified according to age, sex, level and number of fractures, bone mineral density, body mass index (BMI), collapse rates, and history of spine fractures. Pain scores using VASs were assessed at 1 week and at 1, 3, 6, and 12 months.

Results

A total of 259 patients were enrolled, and 231 patients (82 of 91 patients in the kyphoplasty group [KP] and 149 of 168 patients in the conservative treatment group) completed the 1-year follow-up. About 65% of patients were treated successfully with conservative treatment. Risk factors for failure of 3 weeks of conservative treatment were older age (older than 78.5 years), severe osteoporosis (t score less than −2.95), overweight (BMI more than 25.5), and larger collapse rates (more than 28.5%). There were significant reductions in VAS and ODI scores in both groups at each follow-up assessment. At the first month, better clinical results were observed in KP. However, there were no significant differences in outcome measures between the two groups at 3, 6, or 12 months. Thirteen subsequent compression fractures (five in KP and eight in the conservative treatment group) occurred during the 1-year follow-up period.

Conclusion

Both treatments of OVCF showed successful clinical results at the end of the 1-year follow-up period. Kyphoplasty showed better outcomes in the first month only. Given these results, prompt kyphoplasty should not be indicated in the case of a patient with OVCF that has no risk factors for failure with conservative treatment. Rather, a trial of conservative, 3-week treatment would be beneficial.

Modified unilateral transpedicular percutaneous vertebroplasty for treatment of osteoporotic vertebral compression fractures

Objective: To comparatively assess the clinical outcome of modified unilateral percutaneous vertebroplasty for the treatment of osteoporotic vertebral compression fractures. Methods: The clinical outcome and incidence of cement extrusion in a consecutive group of 70 patients at our institution between December 2005 and December 2008 was retrospectively reviewed. Thirty‐five patients were randomly distributed to modified percutaneous vertebroplasty (Group A) and 35 to traditional percutaneous vertebroplasty (Group B). A visual analog scale (VAS) was used on the first post‐operative day and 1 year later to assess the severity of pain before and after vertebroplasty. The incidence of cement extrusion on CT scan was also compared between the two groups. Results: The treatment was successful in all seventy patients. The incidence of cement extrusion was 14.29% (5/35 patients) in group A, and 37.12% (13/35 patients) in group B, this difference being statistically significant (P < 0.05). No patients had serious complications. Complete pain relief was achieved in 50 patients, and significant relief in the other 20 (20/70 patients). There was no statistically significant difference between Groups A and B. Conclusion: Modified percutaneous vertebroplasty enhances the accuracy of cement injection into the center of the vertebral body, increasing the safety of the procedure with no increase in cost. It is a safer and more easily performed technique for treating patients with osteoporotic vertebral compression fractures than traditional percutaneous vertebroplasty.

目的: 探讨正骨手法结合经皮椎体成形术(percutaneous vertebroplasty,PVP)与单纯经皮椎体后凸成形术(percutaneous kyphoplasty,PKP)治疗骨质疏松性椎体压缩性骨折(osteoporosis vertebral compression fractures,OVCFs)的临床疗效。方法: 回顾性分析2021年1月至2022年6月收治的80例单节段OVCFs患者的临床资料,根据手术方式不同分为治疗组和对照组,每组40例。治疗组男24例,女16例;年龄60~83(70.43±7.31)岁;骨密度-3.30~-2.50(-2.84±0.24) SD;T₁₀ 1例,T₁₁ 4例,T₁₂ 11例,L₁ 7例,L₂ 7例,L₃ 5例,L₄ 3例,L₅ 2例;采用正骨手法结合PVP治疗。对照组男27例,女13例;年龄60~82(68.98±6.94)岁;骨密度-3.40~-2.50(-2.76±0.23) SD;T₁₀ 2例,T₁₁ 3例,T₁₂ 13例,L₁ 11例,L₂5例,L₃ 3例,L₄ 2例,L₅ 1例;单纯PKP手术治疗。比较两组术前、术后3 d及术后3、12个月的疼痛视觉模拟评分(visual analogue scale,VAS)、腰椎Oswestry功能障碍指数(Oswestry disability index,ODI);并比较两组术前、术后3 d及术后12个月伤椎局部后凸角、椎体楔形角和椎体前缘高度比的变化情况。结果: 两组患者均顺利完成手术。两组均获得随访,治疗组随访时间13~22(16.82±2.14)个月,对照组随访时间13~23(16.45±2.56)个月。治疗组3例术中出现骨水泥渗漏;对照组1例术中出现骨水泥渗漏、1例术后出现下肢皮肤感觉障碍;两组并发症比较,差异无统计学意义(P>0.05)。两组术前VAS、ODI比较,差异无统计学意义(P>0.05);治疗后3 d,治疗组VAS (3.68±0.62)分与对照组(4.00±0.72)分比较,差异有统计学意义(P<0.05);两组术后3、12个月VAS、ODI比较,差异无统计学意义(P>0.05)。两组术后3 d及术后12个月局部后凸角、椎体楔形角、椎体前缘高度比较,差异无统计学意义(P>0.05)。结论: 正骨手法结合PVP治疗OVCFs相对于单纯PKP在术后早期疼痛缓解方面更具有优势;在椎体高度恢复方面,正骨手法结合PVP与单纯PKP疗效相近。
