An unconventional indication for open kyphoplasty

BACKGROUND CONTEXT: Kyphoplasty is a means of treatment for painful osteoporotic vertebral body compression fractures. Its efficacy has not yet been totally proven. Even though the conventional percutaneous kyphoplasty is a relatively safe procedure, it is not routinely recommended for use in vertebral body fractures that involve posterior cortical compromise/retropulsion or in fractures associated with neurological deficit. PURPOSE: To see whether the open kyphoplasty procedure can be used in patients with painful vertebral body compression fractures who also have bony retropulsion into the spinal canal. STUDY DESIGN/SETTING: This technical report is based on the experience of one patient. METHODS: A 79-year-old woman with a history of osteoporosis presented with a painful vertebral body compression fracture at T12. Magnetic resonance imaging of her lumbar spine demonstrated an acute compression fracture at T12 with significant decrease in vertebral body height and retropulsion of bone resulting in one-third reduction in canal width. She was not considered a candidate for percutaneous kyphoplasty. Three months after the injury, an open kyphoplasty was performed after a decompression laminectomy at T12. RESULTS: The fractured vertebral body was successfully reduced, and there was no leakage of polymethylmethacrylate into the spinal canal through the fractured posterior cortex using the open kyphoplasty procedure. One month after the operation, the patient was free from mid-back pain and was again able to walk. CONCLUSION: Open kyphoplasty procedure allows direct visualization to the spinal canal. It can be performed safely and effectively in selected vertebral body compression fractures with retropulsed bone associated with neurological deficit.     

Efficacy of percutaneous kyphoplasty in treating osteoporotic multithoracolumbar vertebral compression fractures

Percutaneous kyphoplasty is a minimally invasive technique that has become an effective and routine alternative for managing osteoporotic vertebral compression fractures. This article reports the clinical outcome of a series of 54 cases of osteoporotic thoracolumbar vertebrae compression fractures treated by percutaneous kyphoplasty. Fifty-four patients with confirmed osteoporosis and at least 1 level of thoracolumbar vertebrae compression fracture were retrospectively selected. Pre- and postoperative and last follow-up clinical evaluation and radiological data were analyzed, including change of visual analog scale (VAS), reduced use of painkillers, locomotor activity, Cobb's angle, and average vertebral body height. Mean follow-up was 20.4 months (range, 6-36 months). In all cases, percutaneous kyphoplasty treatment was successful, significantly increasing vertebral body height, diminishing kyphosis in the fractured vertebrae, and decreasing painkiller use. In all patients, percutaneous kyphoplasty partially or completely relieved back pain. No new deformity was found within the follow-up period, nor were any other complications. The cement leakage rate was 3.86% (8 of 207 vertebrae) with percutaneous kyphoplasty, but no neurological or other complaints were received. Percutaneous kyphoplasty is a simple and safe procedure in managing osteoporotic vertebrae compression fractures. It relieves pain quickly, restores vertebral height, prevents further fracture, and improves patient quality of life.

骨质疏松性椎体压缩骨折的微创治疗

骨质疏松性椎体压缩骨折常导致患者疼痛、活动受限，特别是随着老龄人群的增加，其发病率逐渐升高。传统采用保守治疗或者手术治疗效果不理想。近年采用椎体成形术(PVP)或后凸成形术(PKP)微创治疗骨质疏松性椎体压缩骨折，经皮穿刺椎体内注入骨水泥或先用球囊撑开压缩的椎体后再注入骨水泥进行椎体强化，可以达到稳定骨折、恢复椎体力学强度和缓解疼痛的目的=本文就有关这种微创治疗骨质疏松性椎体压缩骨折的最新进展加以综述。

Minimal invasive stabilization of osteoporotic vertebral fractures: a prospective nonrandomized comparison of vertebroplasty and balloon kyphoplasty

OBJECTIVE: During recent years, the benefits of balloon kyphoplasty and vertebroplasty have been frequently discussed for the treatment of osteoporotic vertebral compression fractures. Because of the lack of comparative studies, we performed an investigation to describe the mechanical effects and the impact on life quality during a follow-up period of 2 years. METHODS: Patients with nonrecent fractures of vertebral bodies, ongoing bone remodeling, and major kyphotic deformity were treated with minimal invasive stabilization. The median duration of pain was 8 weeks before surgery. Because of the availability of the equipment, 28 patients were nonrandomly assigned to balloon kyphoplasty and 23 patients to vertebroplasty. The follow-up was performed 2 years after surgery. RESULTS: The kyphotic wedge of the vertebral bodies was decreased 6 degrees by balloon kyphoplasty but not by vertebroplasty. With both methods, we found a rapid decrease of pain down to one-half of the preoperative value. A long-lasting effect on pain was found only after balloon kyphoplasty. In the kyphoplasty group, a decrease of the Oswestry Disability Index (ODI) score was found during the first postoperative year. After 2 years, the ODI was not different from preoperative values in both groups. CONCLUSIONS: In nonrecent fractures, the reduction of the kyphotic wedge by balloon kyphoplasty was superior in decreasing pain persisting over a period of 2 years. The ability to improve disability after kyphoplasty was limited to 1 year. In nonrecent fractures, the consequences of age and osteoporosis seem to equalize the effects of the restored sagittal profile on disability but not on pain.     

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.
