RESUMO
OBJECTIVE: This study aimed to compare clinical characteristics and quality of life (QoL) after vertebral osteomyelitis (VO) based on the status of pathogen detection in microbiological sampling. METHODS: We conducted a post hoc data analysis from a prospective single-center study in a tertiary referral hospital, including VO patients from 2008 to 2020. Data were collected preoperatively (T0) and 1-year post surgery (T1). The primary outcome was QoL, assessed with the Oswestry Disability Index and Core Outcome Measures Index. RESULTS: Data from 133 patients with surgically treated thoracic or lumbar VO were evaluated. The pathogen was detected from cultured intraoperative samples in 100 (75.2%) patients (group 1). Culture remained negative in 33 (24.8%) patients (group 2). Quality of life did not differ significantly between the groups at T1. We observed higher preoperative C-reactive protein values and higher rates of spinal empyema at T0 in group 1. CONCLUSION: Quality of life improved significantly for all patients at T1, but scores remained comparable to those reported by patients with chronic back pain. Quality of life was not affected by pathogen detection. However, attempts to detect pathogens are still indicated due to the concomitant findings, including bacteremia and epidural abscesses, along with the advantages of targeted antibiotic therapy. The most critical step for detection may be avoiding pre-sampling antibiotic administration. Cite this article as: Beyer F, Wenk B, Jung N, Bredow J, Eysel P, Yagdiran A.

RESUMO
BACKGROUND: Isthmic spondylolysis represents the most common cause of spinal pain in adolescent athletes. This article provides an overview of the classification, diagnosis, and treatment options for these conditions, including conservative and operative measures. It also provides a treatment pathway to how young athletes with spondylolysis should be treated. DIAGNOSTICS: Diagnostic imaging techniques are essential for an accurate diagnosis, with CT scans providing additional information for surgical planning. TREATMENT: Conservative treatment focuses on activity modification and physiotherapy, with a phased approach tailored to individual patient needs. Operative intervention may be considered if conservative measures fail, with minimally invasive techniques such as Buck's screw fixation showing promising results. The decision between conservative and operative management should consider factors of the patients' individual profile. In this paper, we present the first treatment algorithm for the treatment of isthmic spondylolysis. Long-term prognosis varies, with most athletes able to return to sport following treatment.

Background: The anatomical reconstruction of the wrist is the aim when treating distal radius fractures. Current literature on the importance of preoperative reduction in fractures that are treated operatively is limited. Methods: This study investigated the effect of the preoperative closed reduction of distal radius fractures on the day of trauma and the time to surgery on postoperative palmar inclination. A total of eighty patients (48 females and 32 males, mean age 55.6 years) were studied retrospectively. All patients were treated with an open reduction and internal fixation. The palmar inclination angle was measured using X-rays by two investigators, and the interobservers and pre- and post-reduction parameters were compared. Results: When the surgical management of closed distal radius fractures is required, neither initial repositioning nor a delay of up to 14 days to the surgical treatment influences postoperative palmar inclination. Conclusions: The significance of preoperative reduction of distal radius fractures without neurovascular or extensive soft tissue damage is limited and is not leading to improved outcomes. When surgery is about to be performed, surgeons should carefully consider if reduction is really vital preoperatively. Level of evidence: III.
RESUMO
Vertebral osteomyelitis (VO) and degenerative spondylolisthesis (SL) are 2 commonly treated spinal conditions. Therefore, in the presented work, the quality of life after surgical therapy of these 2 entities is compared using established scores.In a monocentric study, all patients with VO and SL were prospectively enrolled using the Spine Tango Registry. Surgical procedures included one- or two-stage fusion of the affected segments. Quality of life was assessed using the Core Outcome Measures Index (COMI) and the Oswestry Disability Index (ODI) at time points t0 (0 months), t1 (12 months), and t2 (24 months). Statistical analysis was performed using SPSS. The level of significance was set at 5%.52 patients with VO and 48 patients with SL were included in the analysis. There were no significant differences in age and gender distribution. The length of stay in the SL group was significantly shorter (p < 0.001). ODI at time t0 was significantly higher in the VO group (p < 0.001), whereas COMI scores did not differ significantly (p = 0.155). At time points t1 and t2, the differences between the VO and SL groups were not significantly different for either the ODI score (p = 0.176; p = 0.250) or the COMI score (p = 0.682; p = 0.640).Postoperative quality of life scores after lumbar fusion surgery in SL and VO are comparable despite different indications and medical conditions. In both groups, similar quality of life with in patient with chronic back pain was achieved. This should be considered for the preoperative assessment, as well as for the indication for surgery in SL.
RESUMO
OBJECTIVE: This study aimed to determine threshold values of validated quality of life (QoL) scores, including Oswestry Disability Index (ODI) and Core Outcome Measures Index (COMI), for predicting a successful outcome following surgical treatment of lumbar spondylodiscitis (LS). METHODS: Patients with lumbar spondylodiscitis (LS) undergoing surgery in a tertiary referral hospital were included prospectively from 2008-2019. Data were collected both before surgery (T0) and one year after surgery (T1). QoL was measured using ODI and COMI. The successful clinical outcome was defined by the combination of the following four criteria: no recurrence of spondylodiscitis, back pain ≤4 on visual analogue scale or relief of ≥3 points, absence of LS-related neurological deficit, and radiological fusion of the affected segment. For subgroup analysis, group 1 consisted of patients with a favorable treatment outcome (meeting all four criteria), while group 2 included patients with unfavorable treatment outcome (meeting ≤3 criteria). RESULTS: Ninety-two LS patients (median age = 66 years; age range = 57-74) were analyzed. QoL scores improved significantly. Threshold values for the ODI and COMI were calculated at 35 and 4.2 points, respectively. The area under curve for the ODI was 0.856 (95%-CI 0.767- 0.945; P<0.001) and 0.839 (95% CI-0.749-0.928; P<0.001) for the COMI score. Eighty percent of patients achieved a favorable outcome. CONCLUSION: Objective measurement and evaluation of successful surgical treatment of spondylodiscitis require defined thresholds of quality of life scores. We were able to define such thresholds for Oswestry Disability Index and Core Outcome Measures Index. These can be useful to assess clinically relevant changes and therefore allow a more precise estimation of the post-surgical outcome. LEVEL OF EVIDENCE: Level II, Prognostic study.

STUDY DESIGN: Four orthopedic spine surgeons measured the radiological parameters of pedicle screws in the cervical spine using a postoperative computed tomography (CT) scan. PURPOSE: This study analyzed the insertion angle of CT-navigated insertion of pedicle screws in the subaxial cervical spine and classified them according to their position. OVERVIEW OF LITERATURE: Overall, a pedicle transverse angle of 33.6°-50.2° with a mean angle of 45° relative to the midline has been reported in the literature. METHODS: The insertion angles of 87 pedicle screws inserted using CT-based navigation in the subaxial cervical spine were measured in the postoperative CT. The screw positioning was determined according to the modified Gertzbein and Robbins classification. RESULTS: Total 89.3% (n=78) of the pedicle screws inserted using CT-based navigation showed good placement. The mean insertion angle of the pedicle screws that showed good positioning was 29.9°±9.9°. The pedicle screws showing bad positioning had a mean insertion angle of 26.8°±10.5° (p=0.157). The interobserver reliability showed a reliable measurement intraclass correlation coefficient: 0.994 (95% confidence interval, 0.992-0.996). CONCLUSIONS: The present results show that the insertion angle of the pedicle screws in the subaxial cervical spine was smaller than the actual pedicle transverse angle, as per the literature. One reason for this discrepancy could be that the navigation systems allow the insertion of cervical pedicle screws with a lower convergence.
RESUMO
The usage of embedded systems is omnipresent in our everyday life, e.g., in smartphones, tablets, or automotive devices. These devices are able to deal with challenging image processing tasks like real-time detection of faces or high dynamic range imaging. However, the size and computational power of an embedded system is a limiting demand. To help students understanding these challenges, a new lab course "Image and Video Signal Processing on Embedded Systems" has been developed and is presented in this paper. The Raspberry Pi 3 Model B and the open source programming language Python have been chosen, because of low hardware cost and free availability of the programming language. In this lab course the students learn handling both hard- and software, Python as an alternative to MATLAB, the image signal processing path, and how to develop an embedded image processing system, from the idea to implementation and debugging. At the beginning of the lab course an introduction to Python and the Raspberry Pi is given. After that, various experiments like the implementation of a corner detector and creation of a panorama image are prepared in the lab course. Students participating in the lab course develop a profound understanding of embedded image and video processing algorithms which is verified by comparing questionnaires at the beginning and the end of the lab course. Moreover, compared to a peer group attending an accompanying lecture with exercises, students having participated in this lab course outperform their peer group in the exam for the lecture by 0.5 on a five-point scale.
RESUMO
Introduction Because of recent increases in life expectancy, lumbar spinal stenosis (LSS) has become one of the most common degenerative changes in the spine. In patients not responding to conservative therapy, microsurgical decompression is the gold standard of operative treatment for degenerative LSS. The goal of the current study is to evaluate quality of life after microsurgical decompression for LSS, using data from the DWG Register (previously Spine Tango). Methods 36 patients were included in this single-center, prospective, observational study from January 2013 to June 2014. Data were collected from the Spine Tango or DWG Register. The core outcome measure index (COMI), Oswestry Disability Index (ODI), and the quality of life questionnaire EuroQoL-5D were used. Data were collected prior to surgery as well as six weeks, six months, and twelve months after the operation. Results The patient cohort comprised 13 females and 23 males (36.1 and 63.9â%). Complete 12-month follow-up data on 21 patients were available for analysis. Compared to preoperative measures, the COMI score increased 8.1 ± 1.5 over the entire follow up, with 4.5 ± 3.1 at 6 weeks (p < 0.001), 4.8 ± 3.1 at 6 months, and 3.8 ± 3.2 at 12 months. ODI scores, measuring spinal function impairment, were significantly better than preoperative values overall (47.5 ± 17.3) and after 6 weeks (29.1 ± 22.4; p < 0.005), 6 months (30.0 ± 19.3), and 12 months (23.8 ± 18.2). Quality of life measures improved in a similar manner (preoperative: 0.36 ± 0.38; 6 weeks: 0.57 ± 0.34 (p < 0.019); 6 months: 0.62 ± 0.28; 12 months: 0.67 ± 0.31). Conclusion Our study shows that LSS patients without previous surgery and neurologic deficits can expect significant pain relief and improved quality of life already six weeks after undergoing stabilizing decompression. There was an increase in positive postoperative effects over 12 months. The DWG Register provides a standardized and validated means to compare non-operative and operative treatments of the spine over the long term.

BACKGROUND AND OBJECTIVE: Non-operative treatment is widely accepted for early stages of lumbar spinal stenosis. In general, a trial of conservative treatment is recommended prior to surgery. However, there is an ongoing debate regarding benefits from non-operative treatment and their duration. METHODS: Thirty-eight patients were included in this prospective study. All patients received repeated epidural injections and facet joint injections as well as physiotherapy during a one week hospitalization. Patient characteristics, VAS scores, COMI and ODI scores and SF-36 were assessed prior to and immediately after treatment as well as after six, twelve, and 26 weeks. For six weeks after treatment, patients were asked to record a pain diary. RESULTS: Back and leg pain scores improved significantly on VAS up to three months follow-up. COMI score improved significantly over the entire follow-up. Regarding quality of life, mental sub-scores showed no improvement. Physical component summary scores improved for the first three months. CONCLUSIONS: Non-operative treatment offers pain relief and improves physical function for three months. COMI scores improve up to six months follow-up. Spine Tango registry offers standardized instruments for outcome evaluation of non-operative treatment.

INTRODUCTION: The field of shoulder endoprothetics has undergone a rapid development in the last years. The purpose of the study was to provide an overview of the development of shoulder arthroplasties in Germany from 2005 until 2012. This study hypothesized that the surgical procedures of the shoulder joint is still increasing and have not reached a plateau until 2012. METHODS: Data of the German federal statistical office from 2005 until 2012 were analyzed to quantify hemiarthroplasty, anatomic total shoulder and reversed total shoulder arthroplasty rates depending on age, gender and main coded indications. Procedure codes and diagnosis were analyzed for each year. Comparative analyses were used to visualize the difference between the types of shoulder endoprostheses. RESULTS: A total number of 139.272 shoulder arthroplasties were performed between 2005 and 2012. Total should arthroplasties have increased continuously until 2009. In 2009 more total shoulder arthroplasties have been performed than hemiprothesis implantations, which have culminated in 2008. All in all, women have been treated 3-fold higher than men regarding hemiarthroplasty, total shoulder arthroplasties or reversed total shoulder arthroplasties. Under the age of 60 years the majority of treated patients were male. CONCLUSION: Since 2005 shoulder arthroplasties are still increasing in Germany, whereas a slight reduction could be detected for shoulder hemiarthroplasty from 2009 up until 2012. Meanwhile total shoulder arthroplasties and reversed total shoulder arthroplasties are still increasing. Women have experienced a 3-fold higher hemiarthroplasty, total shoulder and reversed shoulder arthroplasties than men except for individual younger than 60 years.

BACKGROUND: Simple elbow dislocation is a complex soft-tissue injury that can cause permanent symptoms. Its incidence is 5 to 6 cases per 100 000 persons per year. Its proper treatment is debated; options range from immobilization in a cast to surgical intervention. METHODS: We systematically reviewed the literature on the treatment of simple elbow dislocation and performed a meta-analysis, primarily on the basis of clinical scores and secondarily with respect to pain, range of motion, and return to work. RESULTS: A randomized controlled trial (RCT) showed that clinical results at short-term follow-up were superior for early functional treatment compared to immobilization in a cast. Brief immobilization, however, reduced pain initially, and the long-term results of early mobilization and immobilization in a cast were the same. Our meta-analysis showed that early mobilization enables patients to return to work earlier (difference of mean values -2.91, 95% confidence interval [CI] -3.18 to -2.64), and that the extent of soft-tissue injury is correlated with the clinical outcome (inverse relationship; difference of mean values -12.07, 95% CI -23.88 to -0.26). Surgical and conservative treatment were compared in a single RCT, which revealed no significant difference in outcomes. A meta-analysis of two retrospective comparative studies showed no advantage of immediate ligament repair over delayed surgery. CONCLUSION: Early functional treatment is the evidence-based therapeutic standard for simple elbow dislocation. The past few years have seen further developments in surgery for simple elbow dislocation. Further study is needed to determine whether surgery for elbow dislocation with high-grade instability can prevent persistent pain, limitation of motion, and chronic instability.

INTRODUCTION: The purpose of the study was to investigate differences in the osseous structure anatomy of male and female distal radii. METHODS: Morphometric data were obtained of 49 distal human cadaveric radii. An imprint of the distal edge was attained using silicone mass and the palmar cortical angle (PCA) of the lateral and intermediate column, here declared as medial, according to the concept of Rikli and Rigazzoni. The lateral and medial length and five widths were digitally measured by three observers. In order to compare the measurements an unpaired t test was used. To prove the reliability of the measurements an intraclass correlation analyses was done. RESULTS: Overall mean medial PCA was 148.25° (SD ± 6.83) and mean lateral PCA 156.07° (SD ± 7.00). In male specimens, the mean medial PCA was 147.38° (SD ± 6.01) and mean lateral PCA was 153.6° (SD ± 6.20) whereas in female specimens, the mean medial PCA was 149.41° (SD ± 7.79) and the mean lateral PCA 159.37° (SD ± 6.78), with statistical significance for the female lateral PCA. No gender significant difference for the medial PCA and no significant side difference for the PCA's could be found. The ICC of the observers was r = 0.936 and 0.976 for the medial and for lateral PCA 0.957-0.984. The palmar cortical length of the distal radius was significantly longer in male specimens. For all widths, larger values for male radii were measured, being statistically significant in all cases. CONCLUSION: Male dimensions concerning the wide were significantly larger when compared with females. Regarding the PCA at the medial and lateral column, we found significant difference for lateral PCA concerning the gender. Overall, study results demonstrated an angle of 148.25° ± 6.83 for the medial PCA and 156.07° ± 7.00 for the lateral PCA.

BACKGROUND: Orthoses are external aids that are often used to treat pain and diseases affecting the spine, such as lumbago, whiplash, and disc herniation. In this review, we assess the effectiveness and complications of orthotic treatment for typical spinal conditions and after spinal surgery. The orthotic treatment of fractures and postural abnormalities are beyond the scope of this article. METHOD: This review is based on a selective search in the Medline database with consideration of controlled trials, systematic reviews, and the recommendations of the relevant medical societies. RESULTS: Three relevant systematic reviews and four controlled trials were found. Very few controlled trials to date have studied the efficacy of orthotic treatment compared to other conservative treatments and surgery. No definitive evidence was found to support the use of orthoses after surgery, in lumbar radiculopathy, or after whiplash injuries of the cervical spine. In a single trial, short-term immobilization was an effective treatment of cervical radiculopathy. Orthoses are not recommended for nonspecific low back pain. The potential complications of cervical orthoses include pressure-related skin injuries and dysphagia. CONCLUSION: No definitive evidence as yet supports the use of orthoses after spinal interventions or in painful conditions of the cervical or lumbar spine. They should, therefore, be used only after individual consideration of the indications in each case.
