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.

OBJECTIVE: The purpose of this study was to evaluate the efficacy of balloon kyphoplasty for treating Kummel disease accompanying severe osteoporosis. METHODS: Twelve patients with single-level Kummell disease accompanied by severe osteoporosis were enrolled in this investigation. After postural reduction for 1 or 2 days, balloon kyphoplasty was performed on the collapsed vertebrae. Clinical results, radiological parameters, and related complications were assessed at 7 days, 1 month and 6 months after the procedure. RESULTS: Prior to kyphoplasty, the mean pain score (according to the visual analogue scale) was 8.0. Seven days after the procedure, this score improved to 2.5. Despite the significant improvement compared to preoperative value, the score increased to 4.0 at 6 months after the procedure. The mean preoperative vertebral height loss was 55.4%. Kyphoplasty reduced this loss to 31.6%, but it increased to 38.7% at 6 months after the procedure. The kyphotic angle improved significantly from 22.4°±4.9° (before the procedure) to 10.1°±3.8° after surgery, However, the improved angle was not maintained 6 months after the procedure. The mean correction loss for the kyphotic deformity was 7.2° at 6 months after the procedure. Three out of 12 patients sustained adjacent fractures after balloon kyphoplasty within 6 months. CONCLUSION: Although balloon kyphoplasty for treating Kummell disease is known to provide stabilization and pain relief, it may be associated with the development of adjacent fractures and aggravated kyphosis.

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.

Percutaneous vertebroplasty and balloon kyphoplasty have been accepted as effective treatment modalities for vertebral compression fractures in patients with vertebral metastasis. However, when these procedures are conducted in patients with lytic lesions of the vertebral pedicle, polymethylmethacrylate leakage through the lytic lesions that occurs during percutaneous pediculoplasty can increase the procedural risks due to the immediate vicinity of neural structures. In spite of this risk, there are not many available reports on safer methods of pediculoplasty. Here we report a case of vertebral metastasis in which the pedicle infiltration of cancer was successfully treated by pediculoplasty using a bone filler device that contained thick bone cement during a balloon kyphoplasty procedure.
