Objective: This study aimed to evaluate the association between preoperative anticoagulant use and time to surgery, hospital length of stay, and 30-day postoperative complications in elderly patients with proximal femur fractures. Methods: This study included 572 patients with low-energy proximal femur fractures who required surgical treatment. Patients were categorized into two groups based on anticoagulation therapy use. The following data was collected and compered between the groups: time from hospitalization to surgery, hospital length of stay, percent changes in hemoglobin and other post-operative complications: death, cardiac complications, sepsis, deep venous thrombosis, pneumonia, urinary tract infection, surgical site infection, pressure ulcers, acute kidney injury and delirium. Multivariate regression analysis was performed to analyze possible confounders. Results: The median age of study participants was 83 years. 78.2% being female. Anticoagulation therapy was used by 19.9% of patients, predominantly non-vitamin K oral anticoagulants. Patients receiving anticoagulants experienced significantly longer hospital stays (median 9 vs. 7 days; P < .05) and surgical delays (median 3 vs. 2 days; P < .0001) compared to those without anticoagulation. Complication rates and hemoglobin level changes did not differ significantly among the groups (P > .05). Multivariate analysis identified age, time to surgery, and hospital length of stay as independent predictors of 30-day postoperative complications, with age and hospital stay also significantly associated with 30-day mortality. Conclusion: Anticoagulation therapy did not directly increase 30-day postoperative complications or mortality but was associated with surgical delays and prolonged hospital stays, which negatively impacted outcomes. Delayed surgery and extended hospitalization emerged as key risk factors. These findings underscore the clinical importance of minimizing surgical delays in anticoagulated patients to improve postoperative outcomes. Level of Evidence: Level II, Prognostic study.Cite this article as: Masionis P, Derkintytė D, Bogdzevič EF, Bobina R, Šatkauskas I.

Background and Objectives: The Western Ontario Shoulder Instability Index (WOSI) is a disease-specific self-administered questionnaire which is designed to measure health-related quality of life for patients with shoulder instability. The objective of this study was to translate and adapt the WOSI questionnaire for the Lithuanian-speaking population and investigate the psychometric properties of the Lithuanian version of the WOSI questionnaire (WOSI-LT): validity, reliability, and responsiveness. Materials and Methods: The WOSI scale was translated into Lithuanian using D. E. Beaton’s systematic and standardized guidelines for cross-cultural adaptation of patient-administered scales. Subsequently, the psychometric properties of the Lithuanian version of the scale (WOSI-LT) were investigated. The study involved 40 patients who reported shoulder instability and underwent surgical treatment. All patients completed the WOSI-LT, QuickDASH, and SF-12 scales. A subset of 10 patients was selected for the reproducibility and responsiveness evaluation. Based on the obtained data, the reliability, validity, and responsiveness of WOSI-LT were examined using statistical analysis methods. Results: The Lithuanian adaptation of the WOSI questionnaire exhibited a high degree of internal consistency, evidenced by a Cronbach’s alpha of 0.93. Its reproducibility was commendable with an intraclass correlation coefficient (ICC) value of 0.90. When assessing correlations, WOSI-LT demonstrated a stronger relationship with QuickDASH (r = 0.64) than with SF-12 (physical component score (PCS) 0.61, mental component score (MCS) 0.33). Six months post-operation, the responsiveness of the WOSI-LT was particularly notable, with a standardized response mean (SRM) of 0.91, the highest among the three scales. Furthermore, no floor or ceiling effects were identified in the scores of the Lithuanian WOSI. Conclusions: WOSI-LT is a valid, reliable, and responsive questionnaire that correlates excellently with the original English version of the scale. This scale can be used in Lithuanian medical institutions to assess the severity of patients’ shoulder instability and evaluate their progress during treatment.

Spinopelvic dissociation is a transverse sacral fracture in conjunction with a vertical fracture of the sacrum on both sides, which causes the dissociation of the upper sacrum and spine from the pelvis. The most common causes of these fractures are high energy injuries such as falls from height or motor vehicle accidents. Spinopelvic dissociation is rare and heterogenous with severe associated injuries. The aim of this study was to assess the injury characteristics, changes in the quality of life and functional outcomes in the 1-year period after spinopelvic dissociation. During the period of 4 years (January 2016 and January 2020), 17 patients with spinopelvic dissociation were admitted to our centre and included in this single-centre prospective cohort study. One patient died during the admission; therefore 16 patients were enrolled in the analysis. Patients were followed-up for 12 months. The quality of life changes were evaluated via the SF-36 questionnaire, and the functional outcomes were evaluated using the Majeed pelvic score. Patients completed their questionnaires twice: firstly during hospitalization (regarding their pre-traumatic condition); and once again 1 year after their injury (regarding their current condition). The mean age of the patients was 40.2 ± 17.7 years. Mean Majeed, PCS and MCS scores of SF-36 before the injury were 95.81 ± 9.50, 55.87 ± 8.89, and 43.76 ± 12.45, respectively. Mean Majeed, PCS and MCS scores 1 year after the injury were 71.13 ± 20.98, 43.45 ± 9.64, and 43.41 ± 7.56. During the period of 1 year after the injury, Majeed and PCS results reduced statistically significantly (P = 0.001 and P = 0.003, respectively), while MCS results remained similar (P = 0.501). According to the data of our study, for patients with spinopelvic dissociation functional outcomes are significantly reduced and only one-third of the patients achieved pre-traumatic functional outcomes 1 year after the injury.

Background and Objectives: Lateral compression injuries of the pelvic ring are most common among young and elderly patients. Of all pelvic ring fracture injuries, the B2.1 type—involving lateral compression of the pelvic ring—is the most common. Despite this, we still have no high-level evidence to consult when choosing between the surgical and non-operative approaches. The purpose of this research was to compare the short-term functional and quality of life outcomes between operatively and non-operatively treated young patients after a B2.1 type pelvic fracture. Materials and Methods: Patients aged 18 to 65 years with pelvic B2.1 type fractures—according to AO/Tile classification—that were hospitalized in a single trauma center between 2016 November and 2019 September were included in the research. Patients were retrospectively divided into two groups regarding their treatment: non-operative and operative. Functional outcomes were evaluated using Majeed score, and SF-36 was used for the evaluation of quality of life. Patients completed these questionnaires twice: first during hospitalization, regarding their pre-traumatic condition (timepoint I); and again 10 weeks after the injury, regarding their current condition (timepoint II). Results: A total of 55 patients (70.6% of whom were female) with type B2.1 pelvic fractures were included in the analysis, with an average age of 37.24 ± 13.78 years. There were 21 (38.18%) patients with high injury severity, and 37 (67.3%) patients were treated operatively versus 18 (32.7%) non-operatively. Between the two timepoints, Majeed score reduced by 34.08 ± 18.95 for operatively and 31.44 ± 14.41 for non-operatively treated patients. For operatively and non-operatively treated patients, the physical component summary (PCS) of the SF-36 questionnaire reduced by 19.45 ± 9.95 and 19.36 ± 7.88, respectively, while the mental component summary (MCS) reduced by 6.38 ± 11.04 and 7.23 ± 10.86, respectively. Conclusions: We observed that operative treatment of B2.1 type pelvic fractures for young patients is not superior to non-operative in the short-term, because the functional outcomes and quality of life are similar in both groups.

Background and Objectives: There are no valid patient-based pelvic ring function assessment tools in Lithuania. The most widely used instrument is the Majeed Pelvic Score (MPS), which is proven to be an effective tool for assessing pelvic function after pelvic injuries. The aims of our study were: (1) the translation and cross-cultural adaptation of the MPS for the Lithuanian-speaking population, (2) to test the psychometric properties of the Lithuanian version of the MPS (MPS-LT) at follow-up two-time points after pelvic fractures. Materials and Methods: The MPS was translated and culturally adapted. Psychometric properties of the MPS-LT were determined in one patient group (n = 40) at two time-points during follow-up examination from 1.5 to 3 months (mean 2 months) and from 11 to 20 months (mean 12 months). Results: At the mean time of 2 months after trauma, Cronbach’s α of the MPS-LT was 0.65. Correlation of the MPS-LT with the Iowa Pelvic Score (IPS) was r = 0.84 (p < 0.001), and with the Lithuanian SF-36, PCS was r = 0.53 (p < 0.001). At the mean time follow-up of 12 months, Cronbach’s α was 0.86, correlation with the IPS was r = 0.92 (p < 0.001), and with the Lithuanian SF-36, PCS – r = 0.82 (p < 0.001). At the 2-month follow-up, neither floor nor ceiling effects were reached, but at 12 months, 27.5% of patients reached the ceiling effect, while none reached the floor effect. The effect size of the MPS-LT was 1.66. Conclusions: The MPS-LT has limited ability to measure functional outcomes at 2 months after pelvic fracture. In contrast, at the 12-month follow-up examination, the MPS-LT had a good ability to assess pelvic function, and it was sensitive to health changes. The MPS-LT can be used as a pelvic function assessment tool after pelvic fractures for the Lithuanian-speaking population.

Background and Objectives: The treatment algorithm of lateral compression B2 type pelvic fractures are still under debate. Some authors advocate conservative treatment, while others recommend surgical approach. The clear indications for isolated anterior or posterior ring fixation or combined anterior-posterior pelvic ring fixation of B2 type fractures remain unclear. The aim of this study was to compare the functional outcomes and quality of life after isolated posterior pelvic ring fixation and combined anterior-posterior pelvic ring fixation for the treatment of B2 pelvic fractures. Materials and Methods: Patients aged 18 to 65 years with B2 type pelvic fracture hospitalized in a single trauma centre over a period of 3 years were included in the research. Based on the attending surgeon’s preference, patients were treated with isolated posterior or combined anterior-posterior pelvic fixation. The quality of life and pelvic function were assessed using SF-36 and Majeed questionnaires, respectively. Patients filled in the questionnaires twice: during the first hospitalization (concerning their pre-trauma state—timepoint I) and one-year after the injury (timepoint II). Results: A cohort of 32 patients with B2 type pelvic fracture was enrolled in the analysis: 23 (72%) were female and 9 (28%) were male. The mean age was 35.3 ± 11.9 years. In this cohort 13 (41%) patients underwent isolated posterior pelvic ring fixation (group I) and 19 (59%) patients underwent combined anterior-posterior pelvic ring fixation (group II). No statistically significant differences were observed between the groups in both timepoints concerning Majeed, SF-36 PCS and MCS scores. However, in both groups Majeed and SF-36 PCS scores were statistically significantly lower one year after pelvic fracture compared with pre-trauma state, while SF-36 MCS scores did not differ. Conclusions: No differences were found in quality of life and functional outcomes between isolated posterior pelvic ring fixation and combined anterior-posterior fixation for the treatment of B2 type pelvic fractures.

Summary Osteoporosis is a common condition for elderly people. The incidence of osteoporotic pelvic fractures has been increasing. Osteoporotic pelvic fractures are associated with increased mortality rates. Based on the aim of our study, we found out that one-year mortality rate after a pelvic fracture is high and depends on the fracture type. Purpose The aim of this study was to determine the one-year mortality rate in patients aged 65+ with osteoporotic pelvic fractures depending on the type of fracture according to AO/OTA classification. Methods Patients aged 65+ with pelvic insufficiency fractures admitted to a single center between 1 June 2013 and 31 December 2016 were enrolled in the study. The fractures were classified according to AO/OTA classification. The start of the survival time analysis was the date of the injury. The end of the analysis was 31 December 2017 or the date of the patient’s death. Mortality rates were assessed with respect to fracture types using Kaplan-Meier curves. The Cox proportional hazards model was applied to assess the dependence of mortality on the fracture type. Results A total of 105 patients with 95 (90.5%) being female were enrolled in this prospective study. The average age was 80.3 years (95% CI 78.8–81.7). Mean follow-up time was 23.5 months (95% CI 20.7–26.4). According to AO/OTA classification, 30 (28.6%) patients had a type A pelvic fracture, 73 (69.5%) patients—type B fracture, and 2 (1.9%)—type C fracture. Overall, the one-year mortality rate was 23.8% (95% CI 16.8–33.2%). For patients with type A fracture, the one-year mortality rate was 13.3% (95% CI 5.2–31.7%) compared with 27.4% (95% CI 18.6–39.2%) in the group with type B fracture, and this difference was statistically significant (p < 0.001). Conclusions We found that within a year after an osteoporotic pelvic fracture, the number of deaths in the patients having type B pelvic fracture was twice higher than in the patients with type A fracture.

Dislocation of the elbow joint is the second most common dislocation after the shoulder joint. Although this pathology is relatively common, concomitant vascular injuries are rare. We present a case of a patient who sustained a fall on his arm with an outstretched elbow that resulted in a closed simple posterolateral elbow dislocation and delayed thrombosis of the brachial artery followed by two revascularisation surgeries. The physician must always maintain a high index of suspicion for a concomitant vascular injury before and after closed reduction of the elbow joint and have in mind that complete ischemia without any pulsations could be absent because the elbow is surrounded by rich collateral anastomoses. Suspicion should be even stronger in the presence of bony lesions or open injuries. A team of trauma and vascular surgeons has to work hand in hand as surgical treatment with a saphenous graft or direct suture is the first method of choice with the prior requirement of a stable elbow joint.
