Predictors of Acute Compartment Syndrome in Patients With Forearm Fractures: A Systematic Review.

Acute compartment syndrome (ACS) is a critical orthopedic and traumatology emergency arising from elevated pressure within a confined osteofascial compartment, leading to compromised blood circulation and tissue ischemia. This systematic review aims to comprehensively identify and analyze the most predictable risk factors associated with ACS development in patients with forearm fractures. Published articles on ACS were meticulously searched and evaluated on reputable medical databases such as PubMed. The keywords "risk factors associated with the ACS in patients who have sustained forearm fractures"were used to create the search syntax on various databases. Data were gathered on raw prevalence, population under study, and methodology. A total of 10 articles that met the search criteria were identified and included in this review with a total of more than 300,000 patients across the studies. Fracture-related ACS was the most common, followed by soft tissue damage among patients with forearm fractures. This review underscores fractures as primary ACS catalysts, along with the role of soft tissue trauma. Meticulous consideration of these risk factors can enhance clinical decision-making, early detection, and intervention, improving patient outcomes and care quality.

Work-Related Shoulder Pain Among Saudi Orthopedic Surgeons: A Cross-Sectional Study.

INTRODUCTION: Shoulder pain is one of the most frequently reported musculoskeletal conditions that approximately 6.9 to 26% of people experience. Numerous etiologies have been linked to causing shoulder pain, with the most frequent one being rotator cuff tendinopathy. Work-related musculoskeletal pain is prevalent in the medical field in general, but orthopaedic surgeons account for the majority of cases overall. The pain experienced is usually caused by many attributing factors that all relate to either the long hours and physically intensive procedures or the unnatural positions orthopaedic surgeons are put in during their surgeries. This study seeks to shed light on the prevalence, contributing factors, and effect of the complications of shoulder pain among orthopaedic surgeons, a topic unexpectedly understudied, particularly in Saudi Arabia. METHODS: A survey has been developed to ask orthopaedic surgeons at various levels of their careers. The study was conducted in Saudi Arabia, Riyadh. It was a multi-centered study that included both governmental and private hospitals in Riyadh. The collected data included age, gender, BMI, sub-specialty, position, number of surgeries performed per week, and the average time per surgery. In our survey, we used the Shoulder Pain and Disability Index (SPADI) to assess shoulder pain. Ethical approval was obtained for this study by the Institutional Review Board of King Abdullah International Medical Research Center, Ministry of National Guard Health Affairs, Riyadh, Kingdom of Saudi Arabia (IRB/1484/23). RESULTS: Fifty orthopaedic surgeons participated in this study most of whom were male (88%) and fell within the age range of 31-40 years (36%). Regarding their positions, a significant proportion were consultants (54%). In terms of workload, approximately (38%) of the surgeons performed three to four surgeries per week. As for the duration of surgeries, almost half of the participants spent between three and five hours per surgery (48%). When it comes to experiencing pain or difficulties during shoulder activities, a considerable number reported occasional occurrences (36%). Moreover, a substantial majority did not have a history of specific shoulder-related disorders, as (88%) of the participants had none of the mentioned conditions, such as shoulder trauma or disorders like adhesive capsulitis and impingement. Most participants reported difficulties in performing daily activities due to their work-related shoulder pain. Mild pain was the most common reported severity level in all assessed activities. CONCLUSION: The present study showed that orthopaedic surgeons in Riyadh, Saudi Arabia, occasionally experience shoulder pain from their jobs. Most of our sample stated that mild shoulder discomfort made it difficult to conduct daily tasks. This study is limited by a relatively low response rate, which may be attributed to the demanding nature of orthopaedic surgery. To promote health among caregivers throughout the kingdom, more studies should be conducted about shoulder pain.

Outcome of the Masquelet Technique for Complex Bilateral Distal Femoral Bone Defects.

Bone defects are severe conditions caused by various etiologies, including trauma, tumor resection, or chronic osteomyelitis. Different surgical interventions can be utilized to manage such cases, including autologous graft or allograft implantation, distraction osteogenesis, acute shortening, amputation, or the induced membrane technique. Herein, the case of a 39-year-old woman with complex bilateral distal femoral fractures with intra-articular extension is presented. The fractures were accompanied by a significant metaphyseal bone defect, which was managed successfully using the induced membrane Masquelet technique. The patient fully healed despite residual knee joint contractures that did not inhibit her mobility. In conclusion, the Masquelet technique successfully manages complex bone defects and restores functionality even in bilateral simultaneous open bone defects.

A Decade's Perspective on the Orthopedic Workforce in Saudi Arabia.

Background The orthopedic surgery workforce constitutes a vital role in the healthcare system, with data being scarce. Therefore, through this study, we share an overview of the orthopedic workforce distribution, demographic trends, and changes over the past decade in Saudi Arabia. Methods All practicing orthopedic surgeons in Saudi Arabia from January 1, 2010, to December 31, 2021, were included in the study. Data regarding orthopedic surgeons' demographics and numbers were obtained from the Saudi Commission for Health Specialties (SCFHS), whereas the data related to the geographical distribution of orthopedic surgeons was obtained from the Ministry of Health Statistical Yearbook of 2020. Results The ratio of orthopedic surgeons per 100,000 people was 5.42 in 2010, which grew subsequently to 12.29 in 2021. The number of Saudi orthopedic surgeons has been noticeably rising through the years, while a slowly growing pattern can be seen among non-Saudi orthopedic surgeons. In addition, the highest ratios of orthopedic surgeons per 100,000 were in Makkah (1.72), Riyadh (1.26), and the Eastern Region (1.06). Conclusion In this study, we demonstrate the progress of the orthopedic workforce in Saudi Arabia over a period of 12 years. The number of orthopedic surgeons per 100,000 people showed a significant rise due to several factors, one of which is road traffic accidents. Also, although the number of female orthopedic surgeons has been rising lately, they are still much fewer than males in this field. In addition, Saudi Arabia has been developing a new healthcare system via the privatization of some of the governmental hospitals, which will lead to changes in the future workforce and its accommodations.

Prevalence and Predictors of Carpal Tunnel Syndrome Symptoms Among Teachers in Riyadh: A Cross-Sectional Study.

Background Carpal tunnel syndrome (CTS) is a musculoskeletal disorder (MSD) afflicting the upper limbs with a prevalence of approximately 14.4% in the general population. Previous studies have noted the increasing prevalence of MSDs among teachers but have not investigated in depth the prevalence and predictors of CTS symptoms in this population. The aim of this study was to help fill this gap in the literature by investigating teachers working in Riyadh, Saudi Arabia. Methods We conducted this cross-sectional study in Riyadh using an online survey. We distributed the Boston carpal tunnel questionnaire (BCTQ) to schoolteachers in the city through the social media applications Twitter, WhatsApp, and Telegram. We assessed the respondents' symptoms using Univariate association analyses with a Wilcoxon rank sum test for the continuous variables and Fisher's exact test and Pearson's chi-squared test for the categorical variables. We assessed the independent risk factors for CTS by constructing multivariate binary logistic regression models and expressed the results using the odds ratio (OR) and 95% confidence intervals (95% CIs), with p < 0.05 indicating statistical significance. Results The sample for this study included 490 teachers. Among them, the prevalence of moderate to severe CTS symptoms was 40.0%, and self-reported CTS was 9.1%. The teachers who were female, relatively old, left-handed, retired, and spent significant time using a pen, keyboard, and/or blackboard were more likely than those who were male, relatively young, right-handed, and did not spend significant time using a pen, keyboard, and/or blackboard to self-report CTS and exhibit moderate to severe symptoms. Conclusions We found a relatively high percentage (40.0%) of CTS symptoms among teachers working in Riyadh. This finding suggests that any sign of CTS symptoms should be checked to ensure early diagnosis and treatment, which contribute to positive outcomes, particularly given the recent increase in such risk factors for CTS as diabetes, hypothyroidism, and high BMI in populations worldwide.

The pattern of emergency department length of stay in Saudi Arabia: an epidemiological Nationwide analyses of secondary surveillance data.

Background: Emergency department length of stay is a vital performance indicator for quality and efficiency in healthcare. This research aimed to evaluate the length of stay patterns in emergency departments across Saudi Arabia and to identify predictors for extended stays. The study used secondary data from the Ministry of Health's Ada'a program. Methods: Using a retrospective approach, the study examined data from the Ada'a program on emergency department length of stay from September 2019 to December 2021. These data covered 1,572,296 emergency department visits from all regions of Saudi Arabia. Variables analyzed included quality indicators, year of visit, shift time, hospital type, and data entry method. The analysis was conducted using multiple linear regression. Results: The study found that the median length of stay was 61 min, with significant differences among related predictors. All associations were significant with a value of p of less than 0.001. Compared to 2019, the length of stay was notably shorter by 28.5% in 2020 and by 44.2% in 2021. Evening and night shifts had a shorter length of stay by 5.9 and 7.8%, respectively, compared to the morning shift. Length of stay was lower in winter, summer, and fall compared to spring. Patients in levels I and II of the Canadian Triage and Acuity Scales had longer stays than those in level III, with those in level I reaching an increase of 20.5% in length of stay. Clustered hospitals had a longer length of stay compared to the non-clustered ones. Pediatric hospitals had a 15.3% shorter stay compared to general hospitals. Hospitals with data entered automatically had a 14.0% longer length of stay than those entered manually. Patients admitted to the hospital had a considerably longer length of stay, which was 54.7% longer compared to non-admitted patients. Deceased patients had a 20.5% longer length of stay than patients discharged alive. Conclusion: Data at the national level identified several predictors of prolonged emergency department length of stay in Saudi Arabia, including shift time, season, severity level, and hospital type. These results underline the necessity of continuous monitoring and improvement efforts in emergency departments, in line with policy initiatives aiming to enhance patient outcomes in Saudi Arabia.

Mixed-Methods Analysis of a Validated Arthroscopic Knot-Tying Simulator With New Indirect Visualization Condition.

BACKGROUND: Simulation provides low-risk opportunities for surgical trainees to learn and practice fundamental skills. One simulation tool for orthopaedics is the Arthroscopic Knot (ArK) Trainer, which has been validated as an effective simulation tool across multiple methodologies. Previous studies have investigated the ArK Trainer in its basic form using clear plexiglass, which allows direct visualization of tissue anchors. PURPOSE: Using a mixed-methods approach, we assessed and compared junior and senior trainees' Seoul Medical Center (SMC) knot-tying performance under direct and indirect visualization. STUDY DESIGN: Cross-sectional study. METHODS: Fourteen orthopaedic surgery postgraduate trainees at a single medical school were recruited to participate. Trainees tied SMC knots using the Ark Trainer under direct and indirect visualization. A mixed-methods approach was used to evaluate knot-tying proficiency and characterize participants' approach to knot-tying. Knot-tying proficiency was evaluated using validated tools: a task-specific checklist (TSC), a global rating scale (GRS), and a proficiency scale (PS). Participants' approach to knot-tying was characterized using Likert-type questionnaires and semistructured interviews. An α level of .10 was set a priori owing to the small pool of trainees. RESULTS: The 14 participants included 7 junior residents (postgraduate years [PGYs] 1 and 2) and 7 senior residents (PGY ≥3), of whom 3 were fellows (PGY 6). Senior trainees outperformed junior trainees on both versions of the ArK Trainer: clear (GRS, P = .055; PS, P = .075) and covered (TSC, P = .05). Overall, participants performed better under direct visualization conditions (GRS, P = .05). In semistructured interviews, significantly more senior trainees discussed relying on haptic cues while tying knots under direct visualization (P = .021). The majority of trainees agreed that both versions of the ArK Trainer were realistic and appropriate practice formats for their level of training. CONCLUSION: Senior trainees were significantly more experienced than were junior trainees in arthroscopic skill and outperformed them on both configurations: direct (PS and GRS) and indirect (TSC) visualization. Experienced trainees were significantly more likely to report using tactile cues to aid knot-tying under indirect visualization. It is likely that inexperienced trainees rely more heavily on direct visualization and that the use of tactile cues may be an indicator of knot-tying proficiency. Trainees recommended progression from direct to indirect visualization configurations for inexperienced learners.

The Predictive Ability of PV-ACO2 Gap and PV-ACO2/CA-VO2 Ratio in Shock: A Prospective, Cohort Study.

INTRODUCTION: Compromised tissue oxygenation leads to anaerobiosis, leading to organ failure and death. This study attempts to demonstrate the predictive abilities of the Pv-aCO2 gap and Pv-aCO2/Ca-vO2 ratio in shock patients undergoing resuscitation. METHODS: In a prospective study, consecutive patients with shock were included. Timed measurements of Pv-aCO2 gap, ScvO2, lactate, and Pv-aCO2/ Ca-vO2 ratio were obtained. The association between the mortality and each variable at all intervals was analyzed. Receiver operating characteristics curves were built. RESULTS: Fifty patients were enrolled. Intensive care unit survivors had a higher Pv-aCO2/ Ca-vO2 ratio at time 0 (0.21, interquartile range [IQR] 0.14 vs. 0.27, IQR 0.38, P = 0.032) and at 3 h (0.27, IQR 0.08 vs. 0.21, IQR 0.12, P = 0.035).Twenty-eight day survival was higher in patients with a low Pv-aCO2 gap at time 0 (7.5, IQR 7 vs. 4.8, IQR 5, P = 0.007).Baseline Pv-aCO2 gap and Pv-aCO2/Ca-vO2 ratio showed good ability to predict 28-day mortality as seen by AUC 0.728 (95% CI 0.578-0.877, P = 0.007) and 0.711 (95% CI 0.563-0.860, P = 0.013). A cut-off point of Pv-aCO2 gap ≥6 mm Hg identified 28-day mortality (75% vs. 45.5%, P = 0.034). The best cutoff values, at baseline, to predict 28-day mortality were 0.25 for the Pv-aCO2/Ca-vO2 ratio (sensitivity 58%, specificity 85%, LR+ 3.86, LR- 0.49) and 6.3 for the Pv-aCO2 gap (sensitivity 58%, specificity 79%, LR+ 2.76, LR- 0.53). CONCLUSION: This study suggests that Pv-aCO2 gap and Pv-aCO2/Ca-vO2 ratio are discriminating predictors of 28-day mortality and can be used to provide supplementary information during resuscitation in shock.

Knowledge, practices, and opinions of ontario dentists when treating patients receiving bisphosphonates.

PURPOSE: Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is a severe but extremely rare complication of prolonged treatment with bisphosphonates (BPs). Improper treatment or misdiagnosis can have serious repercussions. In some cases, the treatment of BRONJ can require jaw resection, prolonged use of antibiotics, and long hospitalizations. This study aimed to measure the awareness of dentists in the Province of Ontario, Canada about BRONJ and to identify any gaps in their knowledge of the condition and its treatment. In particular, the study aimed to answer questions about the dentists' knowledge of the current guidelines and their opinions and practices related to performing surgical dental procedures in patients taking BPs. MATERIALS AND METHODS: The study involved sending a Web-based questionnaire to a random sample of dentists in Ontario, Canada (n = 1,579). Information about their awareness of BPs, their experiences treating patients presenting with ONJ, their experiences with different surgical procedures in patients taking intravenous or oral BPs, and their awareness of the BRONJ guidelines suggested by the American Association of Oral and Maxillofacial Surgeons was collected. RESULTS: A response rate of 30% was achieved. Sixty percent of responding dentists had a good knowledge of BP and BRONJ; however, only 23% followed the guidelines for surgical treatment of a patient taking BPs, and 63% would refer patients if they were taking BPs. Approximately 50% of responding Ontario dentists were not comfortable treating patients with BRONJ at their current knowledge. CONCLUSION: The finding shows that although 60% of Ontario general dentists and specialists have a good knowledge about BRONJ, most are not comfortable performing oral surgery in patients taking BPs. Those who are comfortable have higher knowledge scores, suggesting greater educational efforts should be made to promote the knowledge of dentists regarding BP, ONJ, and BRONJ.
