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.

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.

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.

Osteoporotic vertebral fracture is a disease condition with high morbidity and mortality, whose prevalence rises with mean increase in the life span. Conventional treatments for an osteoporotic vertebral fracture include bed rest, pain medication and brace implementation, but if the patient's pain is severe, cement augmentation procedures, including vertebroplasty and kyphoplasty, are performed. Vertebroplasty and kyphoplasty are relatively easy procedures that have been reported to be effective in controlling acute pain. But, the risk of complication and additional adjacent segment fracture and their superiority over conventional treatment remain debatable. Therefore, the authors have summarized the procedures, complications, and clinical evidence of vertebroplasty and kyphoplasty in this review.

The authors report 2 patients with benign vertebral compression fracture with intravertebral vacuum. Both patients suffered from back pain after minor back trauma and were treated by kyphoplasty. The spine images of one case shows intra-and inter-vertebral vacuum dots since 1weeks after trauma. The other's shows only intravertebral vacuum dots immediately after trauma and then intravertebral vacuum cleft(Kummell's disease) 5 weeks after trauma. The authors speculate that Kummell's disease(delayed posttraumatic vertebral collapse with intravertebral vacuum cleft) was evolved from untreated or unrecognized vertebral compression fracture. Kummell's disease is not a independent disease entity.

OBJECTIVE: The author measured levels of fluoroscopic radiation exposure to the surgeon's body based on the different beam directions during kyphoplasty. METHODS: This is an observational study. A series of 84 patients (96 vertebral bodies) were treated with kyphoplasty over one year. The patients were divided into four groups based on the horizontal and vertical directions of the X-Ray beams. We measured radiation exposure with the seven dosimetry badges which were worn by the surgeon in each group (total of 28 badges). Twenty-four procedures were measured in each group. Cumulative dose and dose rates were compared between groups. RESULTS: Fluoroscopic radiation is received by the operator in real-time for approximately 50% (half) of the operation time. Thyroid protectors and lead aprons can block radiation almost completely. The largest dose was received in the chest irrespective of beam directions. The lowest level of radiation were received when X-ray tube was away from the surgeon and beneath the bed (dose rate of head, neck, chest, abdomen and knee : 0.2986, 0.2828, 0.9711, 0.8977, 0.8168 mSv, respectively). The radiation differences between each group were approximately 2.7-10 folds. CONCLUSION: When fluoroscopic guided-KP is performed, the X-Ray tube should be positioned on the opposite side of the operator and below the table, otherwise the received radiation to the surgeon's body would be 2.7-10 times higher than such condition.

Osteoporotic vertebral compression fractures (OVF) are an increasing public health problem. Cement augmentation (vertebroplasty of kyphoplasty) helps stabilize painful OVF refractory to medical treatment. This stabilization is thought to improve pain and functional outcome. Vertebroplasty consists of injecting cement into a fractured vertebra using a percutaneous transpedicular approach. Balloon kyphoplasty uses an inflatable balloon prior to injecting the cement. Although kyphoplasty is associated with significant improvement of local kyphosis and less cement leakage, this does not result in long-term clinical and functional improvement. Moreover, vertebroplasty is favored by some due to the high cost of kyphoplasty. The injection of cement increases the stiffness of the fracture vertebrae. This can lead, in theory, to adjacent OVF. However, many studies found no increase of subsequent fracture when comparing medical treatment to cement augmentation. Kyphoplasty can have a protective effect due to restoration of sagittal balance.
