RESUMO
BACKGROUND: Pneumatic tourniquets are frequently employed in extremity surgeries, aiming to enhance intraoperative visibility and minimize blood loss. While their benefits and drawbacks have been extensively studied in lower limb operations, their impact on upper limb procedures, particularly elbow surgery, remains poorly understood. This study investigates the advantages and risks associated with pneumatic tourniquet utilization in elbow surgery. METHODS: A retrospective analysis was conducted on 183 patients who underwent elbow surgery for fractures between January 2019 and September 2023. Patients were categorized into two groups: those who underwent surgery with a tourniquet (WT) and those without a tourniquet (NT). Subgroup analyses were performed based on fracture complexity. Data collected included patient characteristics, tourniquet usage, surgical duration, pre- and postoperative hemoglobin levels, C-reactive protein levels, pain assessments, opioid administration, hospital stay duration, follow-up, complications, and revisions. Statistical analyses were used to identify significant differences and correlations. RESULTS: The use of a tourniquet in elbow surgery yielded several notable outcomes. Patients in the WT group experienced significantly shorter surgical durations and hospital stays. Hemoglobin drop was lower in the WT group, indicating reduced blood loss. However, there were no significant differences in postoperative pain, opioid consumption, or complications between the WT and NT groups. Subgroup analysis revealed that the recorded differences, particularly shorter surgical durations, were more pronounced in complex fractures. CONCLUSIONS: This study shows promising results in the use of pneumatic tourniquets in elbow surgery in terms of enhanced efficiency, reduced blood loss, and overall safety, without compromising patient outcomes. However, the potential influence of perioperative decision-making on tourniquet usage underscores the need for further research to elucidate its role and optimize its application, especially in complex elbow fractures.
RESUMO
BACKGROUND: While predictors for postoperative survival in spine tumour patients have been identified, there is limited evidence for predictors of postoperative Quality of Life (QoL), pain and functional outcome. METHODS: One hundred and fifty-three consecutive patients, who had undergone surgery for symptomatic spinal metastases between June 2016 and April 2019, were interviewed preoperatively and during follow-ups at three, six and 12 months using the EQ-5D-3L, COMI, and ODI questionnaires. Differences in means exceeding the specific Minimal Clinically Important Difference (MCID) values were considered clinically significant. RESULTS: Thirty-three percent of the patients were reported dead after 12 months. Only one metastasis compared to multiple metastases has 7.9 the Odds for an improved EQ-5D-3L score at three months. No neoadjuvant metastatic irradiation has 6.8 the Odds for the improvement at that time against performed radiation. A preoperative ODI score between 50.1 and 100 has 22.0 times the odds compared to the range from 0 to 50 for an improved EQ-5D-3L after three months, and 12.5 times the odds in favour of improved COMI after three months, and 13.6 times the odds for improvement of ODI at the three-month follow-up. A preoperative COMI score ranging from 5.0 to 10 has 21 times the odds of a COMI between 0 and 5 for an improved EQ-5D-3L score and 11 times the odds for an improved ODI after 12 months. Other predictors showed no statistically significant improvement. CONCLUSION: An improvement in QoL, pain and spinal function after 12 months can be predicted by a subjective preoperative poor health condition. Impaired spinal function before surgery, a singular metastasis and no previous irradiation is predictive of improved spinal function and quality of life three months after surgery.

Pleural mesothelioma (PM) is a very aggressive malignancy with a poor prognosis. Most patients receive systemic treatment only; however, some patients may benefit from multimodality treatment. A precise staging of patients undergoing multimodal treatment is mandatory. We investigated the pattern of metastasis in a cohort of patients screened for multimodal treatment to define the extent of staging examinations. Additionally, we investigated the occurrence of metastasis during follow-up. We investigated a single-center experience of 545 patients newly diagnosed and/or treated with PM between the years 2010 and 2022. Patients who were treated naïvely and had a whole set of imaging of the brain were included and further analyzed. A total of 54% of all patients with cerebral imaging had an available 18FDG-PET CT scan. We also recorded metastasis during treatment follow-up. There were 110 patients who had a whole set of imaging (CT = 89% and MRI = 11%) of the brain, and 54% of all patients with cerebral imaging had an available 18FDG-PET CT scan. We identified four patients with cerebral metastasis at the time of first diagnosis, which means that 5.4% of the cohort had cerebral metastasis and 13.3% of all patients in the subgroup with complete data of 18FDG-PET CT had distant non-cerebral metastasis. During the longitudinal follow-up, we found 11 patients with newly diagnosed metastases after a median time of 1.6 years (range: 2 months to 3.3 years) after first diagnosis without metastases. Distant metastases are more frequent in mesothelioma patients than previously thought. This implies that extensive staging is needed for patients selected for multimodal treatment, including brain imaging and 18FDG-PET CT.
RESUMO
BACKGROUND: Monteggia-like fractures (MLF) are complex injuries with high complication rates and frequently unsatisfying clinical results. Total elbow arthroplasty (TEA) represents the only option to salvage the functional requirements in some patients with pronounced posttraumatic arthropathy. This case series provides clinical results of TEA following failed treatment of MLF. METHODS: All patients who underwent TEA from 2017 to 2022 for failed treatment of MLF were retrospectively included in this study. Complications and revisions before and after TEA and functional results, measured by the Broberg/Morrey score, were evaluated. RESULTS: In this study 9 patients with a mean age of 68 (±7; 54-79) years were included. The mean follow-up was 12 (±9; 2-27) months. The main reasons leading to posttraumatic arthropathy were chronic infections (44.4%), bony instability due to coronoid deficiency (33.3%) or a combined coronoid and radial head deficiency (22.2%) and non-union of the proximal ulna with radial head necrosis (11.1%). The mean number of surgical revisions between primary fixation and TEA was 2.7 (±1.8; 0-6). The revision rate following TEA was 44%. The mean Broberg/Morrey score at the time of the latest follow-up was 83 (±10; 71-97) points. CONCLUSION: Chronic infection and coronoid deficiency are the main reasons for posttraumatic arthropathy after MLF leading to TEA. While the overall clinical results are satisfying, the indications should be reserved for selected cases due to high revision rates.

BACKGROUND: Small-cell lung cancer (SCLC) is highly aggressive with a nearly incurable disease in most cases. The most important prognostic factor is the status of the mediastinal lymph nodes. Only a small proportion of patients can be diagnosed at early stages and directed to curative multimodal treatment. Therefore, accuracy of nodal staging by (18F)-Fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) computed tomography (18F-FDG-PET/CT) in (very) limited disease SCLC, although not well investigated, is highly important. METHODS: Treatment naive, non-bulky patients treated or diagnosed with SCLC between June 2012 and April 2020 with complete data including FDG-PET/CT and invasive mediastinal staging were retrospectively analyzed (n = 19). Sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV) and accuracy of mediastinal lymph node staging of 18F-FDG-PET/CT was calculated. RESULTS: The FDG-PET/CT showed a sensitivity of 91%, and the specificity was calculated as 87.5%. In this cohort, the disease prevalence in lymph nodes was 58% (n = 11). Positive predictive value was 91%, NPV 88% and accuracy calculated at 89%. One patient was upstaged from single-level N2 to multilevel N2. In one patient, upstaging in invasive staging was performed from N2 to N3, and one patient was downstaged from N1 to N0. CONCLUSIONS: FDG-PET/CT is a valuable tool for the detection of distant metastases, but in mediastinal staging of SCLC some limitations might remain. Invasive methods remain the gold standard. Therefore, the mediastinal lymph nodal status of patients with SCLC screened for multimodal treatment should be further evaluated by additional invasive techniques to verify the exact N-staging and to optimize treatment stratification.

Purpose: Sonographic hip examination according to Graf is widely accepted standard for diagnosing developmental dysplastic hips (DDH) but it is criticized for alleged intra- and interobserver variations. This review was conducted to evaluate whether objective quality criteria according to the Graf method are fulfilled within scientific literature. Methods: A systematic literature search on Pubmed was performed using the search string: [(DDH) OR (Hip dysplasia)] AND (Graf). Studies suitable by title, abstract, manuscript, containing an image of sonographic hip examination and online accessibility were included into analysis. Results: 131 studies were included into final analysis. Only 68 (51.9%) presented correct sonographic images according Graf's criteria. 98 (74.8%) studies plotted alpha-angles (angle between bony roof line and base line) but only 85 (64.8%) studies beta-angles (angle between cartilage roof line and base line). Studies were contributed from 25 countries. Conclusion: Assumingly, skepticism regarding the Graf method is based on user errors and insufficient application of the Graf quality assessment algorithm resulting in high intra- and interobserver variations. When performed correctly, the Graf method is of high diagnostic value.
