IntroductionIn elderly patients with reduced bone quality, insufficiency fractures of the sacrum are relatively common and are typically associated with severe disabling pain. The objective of the present study was to examine the feasibility of cement augmentation by CSP, to determine post-interventional leakages and other complications, and to present the outcome of pain over the course of 18 months.Materials and methodsIn 23 patients (20 women and 3 men) with an average age of 81.3 (71–92) years, a total of 41 sacral fractures were detected by MRI, 5 of them unilateral and 18 bilateral. Conservative treatment initially performed over a period of 3 weeks did not bring any satisfactory reduction in the severe disabling pain. The indication for intervention was established after an interdisciplinary case conference. The intervention was performed under intubation anaesthesia. Single-shot antibiotic prophylaxis was given routinely immediately prior to the intervention. Under sterile conditions, a Jamshidi needle was then advanced into the respective fracture zone in the sacrum from dorsal to ventral (short axis) or from lateral to medial transiliac (transiliac axis). After removing the inner needle, a flexible osteotome was inserted through the positioned hollow needle and used to extend the spongious space in the fracture zone and thus prepare a cavity for the cement filling. High-viscosity PMMA cement was then inserted discontinuously with the aid of a pressure gauge under low-dose CT control. Cement leakages were determined in the CT image on the day after the intervention, all cement outside of the cortical boundary being rated as a leakage. Pain was documented on a visual analogue scale (VAS) on the day before the intervention, on the second day, and 6, 12, and 18 months after the intervention. Additionally occurring complications were recorded, and the patients were asked to rate their satisfaction after 6 and 18 months.ResultsCSP was technically feasible in all patients. In the control CT scan, sufficient cement distribution and interlocking with vital bone were found along the course of the fracture in the sacrum. An average of 6.0 ± 0.83 ml of cement was inserted per fracture. Leakage was found in 5 of 41 (12.2%) of the fractures treated, although none were symptomatic. The mean pain score on the VAS was 8.8 ± 0.59 before the intervention, a significant pain reduction (p < 0.0005) was seen on the second post-operative day, with an average value of 2.1 ± 0.36, and this was stable at 2.2 ± 0.28 after 6, 2.3 ± 0.31 after 12, and 2.2 ± 0.41 after 18 months. Now that they no longer experienced disabling pain, all of the patients were fully remobilised and discharged back home. A high level of patient satisfaction was found after 6 and 18 months.ConclusionAs a minimally invasive procedure, CSP is an effective treatment method for rapid, significant, and sustained pain reduction.
Introduction The objective of this study was a comparative analysis of cement augmentation by means of RFS and CSP with regard to outcome and cost-effectiveness. Patients and Methods CT-guided cement augmentation was performed on 100 patients with a total of 168 non-dislocated insufficiency fractures, 50 patients being treated with RFS and 50 patients with CSP. Leakages were detected by CT. Pain intensity was determined on a VAS before and after the intervention. The patientsʼ self-sufficiency was assessed using the Barthel index. Patients were asked about any complications and their level of satisfaction. Costs incurred for carrying out the procedure were compared with the respective reimbursements received. Results Both procedures were technically fully feasible. No leakages were found in the RFS group, as opposed to 8.1% asymptomatic leakages in the CSP group. The mean value for pain before intervention was 8.8 in the RFS group and 8.7 in the CSP group. On the second postoperative day, there was a significant pain reduction with a value of 2.4 for both groups, which remained more or less constant over the follow-up period. The Barthel index increased significantly from an average of 30 before the intervention to 80 on the fourth postoperative day and 70 after 24 months. No differences were found between the two procedures with regard to pain, improvement in functional status and satisfaction. Taking into account the state-wide base rate used for calculating reimbursement, 3,834.75 € remained for RFS and 5,084.32 € for CSP. Conclusion RFS and CSP are minimally invasive procedures that achieve equally good and sustained pain reduction, leading to markedly improved self-sufficiency of the patients. With regard to possible cement leakages, RFS is the safer method. A profit can be generated with both techniques.
Purpose The objective of this prospective, randomised study was to examine the feasibility and clinical outcome of balloon sacroplasty and radiofrequency sacroplasty. Methods In 40 patients with a total of 57 sacral fractures, CT-guided cement augmentation was performed by means of BSP or RFS. For BSP, the balloon catheter was inflated and deflated in the fracture zone, and the hollow space, thus, created was then filled with PMMA cement. For RFS, the spongious space in the fracture zone was initially extended using a flexible osteotome, and the highly viscous PMMA cement, activated by radiofrequency, was then inserted into the prepared fracture zone. Pain intensity was determined on a VAS before the intervention, on the second day, and 6, 12 and 18 months after the intervention. The results were tested for significance by means of paired Wilcoxon rank-sum tests and Mann-Whitney U tests. Results BSP and RFS were technically fully feasible in all patients. An average of 6.3 ml cement per fracture was inserted in the BSP group and an average of 6.1 ml per fracture in the RFS group. Leakage could be ruled out for both procedures. The mean pain score on the VAS before the intervention was 8.6 ± 0.55 in the BSP group and 8.8 ± 0.58 in the RFS group. On the second postoperative day, a significant pain reduction was seen (p \ 0.001), with an average value of 2.5 (BSP ± 0.28, RFS ± 0.38) for both groups. After 6 (12; 18) months, these values were stable for the BSP group at 2.3 ± 0.27 (2.3 ± 0.24; 2.0 ± 0.34) and for the RFS group at 2.4 ± 0.34 (2.2 ± 0.26; 2.0 ± 0.31). With regard to pain, exceedance probability values of p = 0.86 (6 months), p = 0.94 (12 months) and p = 1 (18 months) were seen, so that neither treatment method leads to differences in results. Conclusions BSP and RFS are interventional, minimally invasive procedures that enable reliable cement augmentation and achieve equally good clinical outcomes in the medium term.
A total of 45 patients have undergone an Inkwell esophagogastrostomy after resection of a benign esophageal stricture. Nineteen patients were available for a long-term follow-up study, showing evidence of gastroesophageal reflux in 16 patients. Due to the high incidence of reflux and subsequent morphologic changes, there was a not negligible late disability. The Inkwell esophagogastrostomy can no longer be recommended in the treatment of an underlying reflux-induced lesion, strictures included.
Background Fragility fractures of the sacrum (FFS) have been detected more and more frequently in recent times, and the incidence will continue to increase due to increasing life expectancy. The aim of this study was to compare the clinical outcome of conservative, interventional and surgical treatment of FFS. Methods Retrospectively, 292 patients (276 women, 16 men) with confirmed FFS were followed up over a period of 2 years. The age of the women was Ø 81.2 (58 - 99) and that of the men Ø 78.1 (76 - 85) years. The pain was quantified using a VAS. Fractures were classified in accordance with the Rommens and Hofmann and with the Denis classification using conventional X-rays, CT and MRI. A QCT of the lumbar spine was performed to quantify bone mineral density. Concomitant diseases of every patient were recorded. An interdisciplinary case conference determined the individual treatment concept considering the age, type of fracture, pain level and comorbidities with classification into conservative, interventional (any type of sacroplasty) or surgical treatment. Over the course pain and independence were measured, complications and patient satisfaction were documented. A vitamin D determination was done, and existing comorbidities were included. Results Patients with a pain level of ≤5 benefited from the conservative therapy measures, with pain levels > 5 significantly delaying the development of mobility. After sacroplasty, the pain reduced significantly, which caused a rapid improvement in mobility without any significant difference being found between vertebro- (VSP), balloon (BSP), radiofrequency (RFS) and cement sacroplasty (CSP). In terms of pain reduction and mobilization, the surgical treated patients benefited from osteosynthesis, although more complex fracture types with lumbopelvic stabilization took longer. Overall, there were no deaths during the hospital stay. Mortality after 12 months was 21.7% for the conservative, 8.4% for the interventional and 13.6% for the surgical therapy group; the differences are significant. For patients in the conservative therapy group who were difficult to mobilize due to pain, the mortality increased to 24.3%. Over 24 months, patients achieved the best independence after sacroplasty. At 12 and 24 months, subjective satisfaction with the therapies was best after sacroplasty, followed by osteosynthesis and conservative measures. All patients had a pronounced vitamin D deficiency and manifest osteoporosis. Cardiovascular pathologies were the main concomitant diseases. Conclusions Patients with FFS with a low level of pain benefit from conservative therapy measures, whereby complications and mortality increase significantly in the case of persistent immobilizing pain. Patients with an unacceptable level of pain resulting from non-dislocated fractures benefit significantly from sacroplasty. Patients with unstable and displaced fractures (Rommens and Hofmann type III and IV) should be operated on promptly. Different techniques are available for sacroplasty and osteosynthesis, which lead to an improvement of independence and a reduction in mortality.
Purpose The objective of the present study was to evaluate the benefit of a thoracic, computed tomography-guided sympathicolysis (CTSy) in patients with primary, focal hyperhidrosis of the hands. In addition, the influence of the amount and distribution of the administered sympathicolytic agent was to be assessed. Patients and Methods Retrospectively, 78 patients [13 (16.7 %) men, mean age 31.2 ± 9 years and 65 (83.3 %) women, mean age 34.2 ± 12 years], who had been treated using CTSy, were included in the study. The indication for treatment was primary focal palmar hyperhidrosis grade II and grade III after exhaustion of all conservative treatment options and a continued high level of suffering. CTSy was performed after establishing the entry plane at the level of the intervertebral space T2 / T3 via a dorsolateral approach using a 22-G coaxial needle. On average 5 (2–10) ml of a sympathicolytic mixture (10 ml consisting of 8 ml 96 % alcohol, 1.6 ml 0.5 % Carbostesin and 0.4 ml 0.9 % NaCl solution, with added amounts of contrast medium) were instilled. The volume of distribution of the sympathicolytic agent was determined in craniocaudal direction using CT images. The patients evaluated their sense of discomfort preinterventionally, 2 days postinterventionally, and 6 and 12 months after the intervention, on the basis of a Dermatology life Quality Index (DLQI) as well as the side effects that occurred. Results The technical success rate of CTSy was 100 %. No major complications occurred. The interventions performed led to a significant reduction (p < 0.001) in the preinterventional sense of discomfort 2 days, 6 and 12 months after CTSy. As the most common side effect, compensatory sweating was reported by 16/78 (20.5 %) of the patients over the further course. In all of these patients, the volume of sympathicolytic agent administered was below 5 ml. In no case did the sympathicolytic agent extend caudally beyond the base plate of Th 3. No compensatory sweating of the back was observed in 5/78 (6.4 %) patients; here the sympathicolytic volume was above 5 ml and extended significantly caudally below the baseplate of T3.Transient miosis and ptosis was found in 8/78 (10.3 %) patients. In all of these patients, the volume of sympathicolytic agent administered was above 5 ml and it extended markedly cranially beyond the upper plate of T2. A mild to moderate recurrent sweating developed in 35/78 (44.9 %) patients, which was more marked if the volume of sympathicolytic administered was below 5 ml and slightly more pronounced on the left than on the right. Given a high level of satisfaction overall, 71/78 (91.0 %) patients said that they would undergo the intervention again. Conclusion For patients with primary, focal palmar hyperhidrosis CTSy represents a therapeutic option that offers good benefit and has few side effects. The amount and spatial distribution of the sympathicolytic agent has an influence on the therapeutic outcome and the side effects. Key Points: Citation Format
