We describe a case of cement leakage from the pedicle of vertebrae to the subcutaneous tissue after kyphoplasty.We attempted to remove all cement leakage, but residual cement remained in the paraspinal tissue without any neurological complications.This case illustrates the importance of the right timing of cement injection and when to detach the bone-filler device from the cement.

One of the main restrictions of vertebroplasty is the high injection pressure that is required to inject sufficient cement into a fractured vertebral body. Kyphoplasty can be used to reduce injection pressure by making a void with a balloon tamp. During vertebroplasty, serious complications such as pulmonary embolism and neurologic compression have been reported, which usually occur when uncontrolled excessive pressure is applied to inject bone cement. We devised a technique of making small voids and connections with the fracture gaps to reduce cement delivery pressure during vertebroplasty that involves a simple modification of the conventional technique. The modification of vertebroplasty using a curved probe may be used to control the cement injection easily during the procedures and minimize complications related to cement leakage.

Single-balloon kyphoplasty via an extrapedicular approach has been reported to be effective because it requires less time than conventional two-balloon kyphoplasty and has comparable therapeutic efficacy. However, single-balloon kyphoplasty is not popular because the extrapedicular approach is believed to be complicated and unsuitable for the thoracolumbar and lumbar spine. The authors describe a standardized surgical technique that utilizes a far-lateral extrapedicular approach for single-balloon kyphoplasty, which can be performed in any part of the spine by physicians without substantial difficulty.

Kyphoplasty has recently attended as a potential treatment for sacral insufficiency fracture. We report a 85-years-old female patient with osteoporotic S1 insufficiency fracture with absence of trauma history treated with kyphoplasty which has no symptom improve with conservative treatment. Kyphoplasty is an effective and useful procedure in the treatment of the sacral insufficiency fracture, additionally reviewed of the literatures.

Vertebral compression fractures result in vertebral height loss and alter sagittal spinal alignment, which in turn can lead to increased morbidity and mortality. Acute osteoporotic vertebral compression fractures are known to increase mobility and instability of the spine. There are limited published data correlating the degree of dynamic mobility and the efficacy of kyphoplasty on vertebral compression fractures. Here we report a 73-year-old female with a severe acute osteoporotic L2 compression fracture who obtained total vertebral height restoration following kyphoplasty, with resolution of back pain.

Kummell's disease is a spinal disorder characterized by delayed post-traumatic collapse of a vertebral body with avascular necrosis. Although definitive treatment for Kummell's disease has not been established, it has been reported that percutaneous vertebroplasty or kyphoplasty has shown good results. However, these procedures are not recommended for severely collapsed vertebral bodies because of the risk of cement leakage or technical difficulties. Authors report a rare case of spontaneous reduction in vertebral height by the insertion of a working cannula into the vertebral body in Kummell's disease.

PURPOSE: We are to find the method to objectify postoperative prognosis, analyzing the factors confluencing the result of kyphoplasty in osteoporotic vertebral compression fracture (OVCF). MATERIALS AND METHODS: Our study included 50 patients (55 vertebral bodies) who have undergone kyphoplasty from Sep. 2004 until Oct. 2005. We divided in the group according to bone mineral density (BMD), compression rate, recovery rate and cement leakage. We verified the significance of each group, using independent t-test, and ANOVA test among observers. RESULTS: We performed kyphoplasty on 55 vertebral bodies, 12 cases with more than 0.4 g/cm2 in BMD (mean: 0.53 g/cm2) and their mean preoperative compression rate (CR), immediate postoperative recovery rate (RR-IPO), and recovery rate after 6 months (RR-6M) was each 30.58%, 12.35%P, 9.93%P. 15 cases under 0.4 g/cm2 (mean 0.31 g/cm2), and their CR, RR-IPO and RR-6M was 26.73%, 11.77%P, 5.26%P respectively. The p-value was 0.004. Another studies according to CR, RR-IPO and leakage of cement revealed the better results in the cases of the lower CR, the smaller reduction and abscecnce of cement leakage, but statistically insignificant (p=0.309, 0.069, 0.356). CONCLUSION: Preoperative BMD was most important factor that confluencing postoperative radiological result in OVCF. Other factors were also thought to be confluencing factors, but statistically insignificant..

BACKGROUND: Kyphoplasty is a minimally invasive procedure that can stabilize osteoporotic and neoplastic vertebral fractures. We retrospectively evaluated the clinical outcomes of kyphoplasty for the treatment of vertebral compression fractures in cancer patients. METHODS: We reviewed the clinical data of 27 cancer patients who were treated with kyphoplasty (55 vertebral bodies) between May 2003 and Feb 2008. The clinical parameters, using a visual analog 10 point scale (VAS) and the mobility scores, as well as consumption of analgesic, were evaluated preoperatively and at 1 week after kyphoplasty. RESULTS: A total 55 cases of thoracic and lumbar kyphoplasties were performed without complications. The mean age of the patients was 66 years. All the patients experienced a significant improvement in their subjective pain and mobility immediately after the procedures. The pain scores (VAS), mobility scores and other functional evaluations using the Oswestry disability score and the SF-36 showed significant differences between the pre- and postoperational conditions. CONCLUSIONS: Kyphoplasty is an effective, minimally invasive procedure that can relieve the pain of patients with vertebral compression fractures and these fractures are the result of metastasis.
