We evaluated the effectiveness of Tc-99m labeled antigranulocyte antibody immunoscintigraphy in differentiating the causes of vertebral compression fracture. This study involved 16 patients with vertebral compression fracture; 8 were due to trauma or osteoporosis, 3 were due to metastasis and 5 were due to tuberculous spondylitis. We retrospectively analyzed the location and the extent of decreased tracer uptake in tomographic images of Tc-99m labeled antigranulocyte antibody immunoscintigraphy. Eight patients had a 16 vertebral compression fractures due to trauma or osteoporosis, three patients had 3 vertebral compression fractures due to metastasis and 5 patients had 6 vertebral compression fractures due to tuberculous spondylitis. Sixteen vertebral compression fractures by trauma or osteoporosis showed a normal tracer uptake in pedicle, laminar and spinous process, but there was noted with 6 decreased uptake, 8 absence of tracer uptake and 2 normal tracer uptake in the vertebral body. Two vertebral compression fractures by metastasis showed the absence of uptake in vertebral body, pedicle, laminar and spinous process, and one showed an absence of vertebral body and spinous process. Six vertebral compression fractures by tuberculous spondylitis showed the absence of uptake in six compression fractures, the absence of pedicle in five compression fractures. We concluded Tc-99m labeled antigranulocyte antibody immunoscintigraphy may be helpful to differentiate the causes of vertebral compression fractures.

Osteoporosis is a worldwide problem and it mainly affects postmenopausal women. Osteoporosis associated with pregnancy or lactation is a rare condition. The incidence and mechanism of this phenomenon has not been clarified, but it can cause one or more vertebral compression fractures with severe, prolonged back pain in the affected women. We experienced this uncommon case, treated it with percutaneous vertebroplasty. A 35-old-woman visited our hospital with complaints of severe back pain and flank pain 2 months after normal vaginal delivery. She was diagnosed with osteoporotic vertebral compression fractures on the T5, 8, 9 and 11 vertebral bodies and we performed percutaneous vertebroplasty on the T8, 9 and 11 vertebrae with a good result. We present here an unusual case of pregnancy-associated compression fractures treated by percutaneous vertebroplasty.

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.

Purpose: We evaluate the characteristics of vertebral body fractures in two level flexion-distraction injuries of the thoracolumbar spine Methods: The findings of radiographs, computed tomographs, and MRIs of 43 patients with flexion-distraction injuries combined with vertebral body fractures were retrospectively evaluated. We divided the patients with bursting fractures into two groups, the distractive group (posterior vertebral height ratio >1) and the compressive group (vertebral height ratio <1). Results: There were 23 compression fractures and 20 bursting fractures. In bursting fractures, the distractive group had 5 cases, and the compressive group 15 cases. In 24 cases (55.8%), the interspinous distances were widened. The average of the canal encroachment was 4% in the distractive group and 40% in the compressive group. At last follow-up, the average loss of correction was 2.0 degree in compression fractures and 2.7 degree in bursting fractures. Conclusion: The configurations of vertebral body fractures in flexion-distraction injuries of the thoracolumbar spine were varied as to the location of the axis of flexion. Because bursting fractures in flexion-distraction injuries had distractive or compressive features, one should consider that in establishing operative plan.

Vertebral compression fractures can occur due to trauma, a malignancy, or most commonly, osteoporosis. These fractures are frequently seen in elderly women; 30% of postmenopausal women are affected by vertebral compression fractures. These fragile fractures frequently result in both acute and chronic pain, but more importantly, are a source of increased morbidity and possibly, mortality. These injuries can be treated both conservatively and with surgery. The use of percutaneous vertebral augmentation offers a minimally invasive approach for the treatment of vertebral compression fractures. We experienced two cases of compression fractures diagnosed during the treatment of thoracic postherpetic neuralgia. Two patients suffering from postherpetic neuralgia with a sharp and stabbing pain in the thoracic dermatomes that was unresponsive to conservative treatment were transferred to our clinic. During the management of postherpetic neuralgia, we incidentally found thoracic compression fractures after obtaining fluoroscopic guided images. After a balloon kyphoplasty, the preoperative pain related to the postherpetic neuralgia was successfully relieved soon after the procedure, and there were no complications.

Objective : Percutaneous approach to the middle thoracic vertebra through the transpedicular route for the patients with osteoporotic vertebral compression fractures is difficult due to the small size of the pedicle and parasagittally oriented vertebra body anatomy. The percutaneous vertebral body access [PVBA] technique utilizing the posterolateral extrapedicular approach avoids the pedicle and provides direct access to the vertebral body. The objective of this study is to evaluate the efficacy of the vertebroplasty utilizing PVBA technique for osteoporotic vertebral compression fractures in the middle thoracic vertebrae. Methods : A retrospective review was done on 20 patients who underwent vertebroplasty utilizing PVBA technique performed for painful osteoporotic compression fracture in the middle thoracic vertebrae at 22 levels from May 2003 to June 2006. The average amount of the injected cement was 1.5-2.5ml. The postprocedural outcome was assessed using a visual analogue scale [VAS]. Results : The treated vertebrae were T5 [1 level], T6 [5 levels], 17 [7 levels], and T8 [9 levels]. The compression rate and kyphotic angle were improved after procedure from $18%{\pm}13.4$ to $16%{\pm}13.8$ [p > 0.05] and from $6.9^{\circ}{\pm}6.7$ to $6.6^{\circ}{\pm}6.2$ [p>005], respectively. Preprocedural VAS was $8.2{\pm}0.70$ and was decreased to $2.1{\pm}1.02$ [p < 0.01] after treatment. Postprocedural cement leakage was noted in 3 levels [13.7%]. There were no cases of leakage to epidural space or neural foramen, segmental artery injury, and pneumothorax. Conclusion : These results suggest that the complication rates are low and good results can be achieved with vertebroplasty utilizing PVBA technique for the osteoporotic vertebral compression fractures especially in the middle thoracic vertebrae.

Objective : Kyphoplasty and vertebroplasty are two minimally invasive procedures for osteoporotic vertebral compression fractures. The purpose of this retrospective study was to compare the radiological findings and clinical outcomes between two procedures. Methods : Osteoporotic vertebral fractures were treated in 76 vertebrae, using kyphoplasty (n=35 vertebrae) and using vertebroplasty (n=41 vertebrae). Fractured vertebral bodies were diagnosed by correlating the clinical symptoms with radiologic study. The responses of pain symptoms were measured by a self-reported Visual Analog Scale (VAS) score. Plain X-rays were checked preoperatively and postoperatively at admission and 6 months. The vertebral body height and kyphotic angle were measured to assess the reduction of the sagittal alignment. Results : The mean pain scores were decreased significantly for both procedures postoperatively, but there were no significant differences between two groups. Kyphoplasty led to a significant reduction of the vertebral body height and improvement of kyphotic angle. There were no neurological deficits after kyphoplasty, but one patient experienced paraparesis after vertebroplasty. During the 6 months follow-up both procedures provided stabilization of the sagittal alignment. Conclusion : Kyphoplasty and vertebroplasty are considered effective minimally invasive techniques for the stabilization of osteoporotic vertebral body fractures, leading to a statistically significant reduction in pain. Kyphoplasty significantly restore sagittal alignment. Also, complications and the incidence of bone cement leakage are significantly lesser than vertebroplasty. Therefore, kyphoplasty seems to be reasonable procedure for osteoporotic vertebral body compression fractures when medical treatment fail.

Objective : The aim of this study is to assess the immediate and long-term efficacy of percutaneous vertebroplasty for treating painful vertebral osteoporotic fractures. Methods : A retrospective review of 149patients who had undergone 167 vertebroplasty procedures for osteoporotic fractures was performed. Clinical, radiologic, and procedural datas were analyzed as parameters of prognostic significance, including age, sex, bone marrow density score, symptom duration, bone cement filling grade, number of fractured vertebrae, compression grade of vertebrae, leakage of bone cement, volume of bone cement injected and complications. Results : In 158 of the 167 procedures assessed, immediate pain relief was obtained [94.6%]. The extent of collapse of the vertebral body was assessed as a parameter for prognostic significance [p=0.015]. Three months postoperatively, no improvement of the pain was observed in four of the 167 procedures that had undergone the vertebroplasty [2%]. At long-term follow-up, the improvement of pain was not correlated with the compression grade of vertebrae [p=0.420]. Conclusion : The immediate outcome of vertebroplasty are less effective in vertebrae more collapsed.

Objective: We analyze pain relief, deformity correction and complication rate after percutaneous kyphoplasty for osteoporotic vertebral compression fractures. Methods: The authors retrospectively reviewed medical records and radiological findings of 32 patients who underwent percutaneous kyphoplasty for osteoporotic vertebral compression fractures. Results: The patients had significant pain improvement with the procedure. The visual analogue scale score reduced from 8.6 to 3.4 significantly after the procedure. The midline vertebral body height significantly increased postoperatively, but mean kyphotic angle did not. There was no serious complication except one case of epidural cement leakage without neurological impairment. Conclusion: Balloon kyphoplasty safely can reduce severe back pain and returned geriatric patients to higher activity levels. The midline vertebral height is restored significantly. However kyphotic deformity correction is not significant as contrary to what we expected from the present study before it was carried out.

Background: Balloon kyphoplasty is the new technique that helps to decrease the pain and improve mobility as well as restore the vertebral body height and kyphotic curve in fractured vertebrae. We evaluated the outcome of balloon kyphoplasty in the reduction of vertebral body height, kyphotic curve and clinical improvement in the patients with painful vertebral compression fractures. Methods: From July 2002 to February 2005, 84 levels of vertebral compression fractures in 66 patients were treated with balloon kyphoplasty. The assessment criteria were the changes over time in visual analogue scale (VAS) and mobility score. We evaluated the vertebral body height and kyphotic curve at preoperative 1 day and postoperative 1 day. Results: Procedures were performed in 66 patients with a total of 84 affected vertebral bodies. The anterior wall height was restored in 74 / 84 (88%) levels with a mean increment of 2.9 mm, and the mid-vertebral body height was restored in 79 / 84 (94%) levels with a mean increment of 4.2 mm. Kyphosis correction was achieved in 60 / 84 (71.4%) from 10.1 degrees to 7.5 degrees. Pain intensity reduced by 60% in one day after operation and by 75-85% in later time. Mobility scores of all patients were improved immediately after the procedure. Cement leakage occurred in 3 levels but there was no clinical problem. Conclusions: Kyphoplasty is an efficient and safe treatment of painful vertebral compression fracture in pain relief, mobility improvement, and reduction of deformity.
