Objective: Pain reduction and improvement in quality of life with sacroiliac joint (SIJ) fusion., Indications: Chronic SIJ-associated pain; positive response to SIJ injection with local anesthetic; positive SIJ provocation tests; failed conservative therapy over 6 months., Contraindications: Non-SIJ-associated pain; tumor/infection/unstable fracture in the implantation area; malformations; tumor or osteolysis of the sacrum or ilium bone; active infection at the implantation site; allergy to metal components; secondary gain from illness, request for a pension; inadequately treated osteoporosis., Surgical Technique: Transarticular placement of Kirschner's wires through the SI joint via minimally invasive lateral approach. Guided preparation of implant site over Kirschner's wires and implantation of 3 triangular, transarticular titanium implants for SIJ fusion., Postoperative Management: Deep vein thrombosis prophylaxis. 3 weeks partial weight-bearing and then moving on to full weight-bearing. X‑ray controls at defined intervals. Physiotherapy., Results: We enrolled 26 patients who were followed up over the period of 4 years. The evaluated endpoints were low back pain on the visual analog scale (VAS 0-10), grade of disability with the Oswestry Disability Index (ODI) and quality of life with the EuroQOL-5D. At 4 years, mean low back pain improved compared to preoperative (VAS preoperative 8.4, VAS 4 years postoperative 4.6). Mean improvements in ODI (ODI preoperative 58.1, ODI 4 years postoperative 32.1) and EQ-5D (preoperative 0.5, after 4 years 0.7) could be evaluated over the long-term period of 4 years. Satisfaction rates were high and the proportion of subjects taking opioids decreased at the 4‑year follow-up (preoperative 82%, postoperative 39%). Implant loosening could not be detected on plain radiograph., (© 2021. Springer Medizin Verlag GmbH, ein Teil von Springer Nature.)

Background: Sacroiliac joint (SIJ) painful dysfunction is a common source of low back pain (LBP). Several surgical treatment options for SIJ fusion were described. A promising treatment option with demonstrated clinical improvement is the minimally-invasive SIJ fusion., Objective: The aim of this case study was to document the effectiveness and safety of the new SIJ system (Torpedo®) over a period of 6 months after the minimally invasive implantation., Methods: Patients with failed conservative treatment of painful SIJ dysfunction were enrolled successively in two centers. The Diagnosis was made by positive response to SIJ-injection with local anesthetic and at least by two positive SIJ provocation tests. The Torpedo® Implant system was used for the implantation. This workpiece made of titanium alloy is characterized by a helical profile geometry (CST: chronical spinal turn) with a hydrophilic surface. The evaluated endpoints LBP and grade of disability were assessed using a 0-10 numerical rating scale (NRS), and Oswestry Disability Index (ODI) preoperatively and at one, three and six months postoperatively., Results: 15 patients (10 female, 5 male; mean age 59 ± 13 years) were operated on one after the other. The pain intensity decreased in all 15 patients. After 6 months, a decrease in the median values of 70% (quartiles 1-3: 65-79%) was calculated. The median values of the Oswestry Disability Index after 6 months were 62% (quartiles 1-3: 53-67) lower than before the operation. Before surgery, 13 patients (87%) were taking opioids for pain management. Six months after the operation, opioids were only needed by 3 patients (20%). Implant malpositioning was not detected on plain radiograph. No surgical site infections or perioperative complications occurred., Conclusions: The clinical improvement in early follow up and the absence of surgery related complications demonstrate a high grade of device-related safety and effectiveness of the treatment with a novel minimally-invasive SIJ fusion system.

Successful treatment of foot and ankle diseases requires an accurate diagnosis. In addition to differentiated history taking, clinical examination is the most important component in the diagnosis of foot and ankle diseases. The present video explains the common provocation tests and functional tests that are used in the basic clinical examination of the foot and ankle complex. In addition to general inspection and palpation, the focus is on different diagnostic tests and clinical signs that improve diagnostic accuracy. The present basic clinical examination methods allow a structured approach to clinical issues and can be a good basis, if supplemented by further specific and individual tests., Competing Interests: The authors declare that there is no conflict of interest./Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Osteoporotic vertebral fractures without prior adequate traumatization are frequent diagnosed in orthopedics because of the increasing life expectancy and incidence of osteoporosis. The associated high mortality is caused by reduced mobilization which leads to a higher risk of infection and a bedridden state. On the other hand the diagnosis of sacral insufficiency fractures is often prolonged because of unspecific symptoms while being associated with similar risks. This article presents an overview of the present scientific literature and a retrospective analysis of patients treated via balloon-assisted sacroplasty. In 8 years, ten patients (three men and seven women) were treated. The average age was 78.4 years and the average time until the diagnosis 4.6 weeks. In most patients a significant pain reduction after the failure of conservative treatment thanks to operative treatment as well as increased mobility was observed. Only one experienced a minor surgical complication being cement leakage with nerval impaction which did not compromise her clinical outcome or satisfaction with the procedure. Balloon-assisted sacroplasty can possibly be seen as an effective symptomatic therapy in osteoporotic insufficiency fractures.
