Background: We analyzed trends in age at surgery and surgical approach over time and geography.

Methods: We performed a systematic review according to PRISMA-IPD guidelines to include individual patient data. Collected data included age at surgery, location of surgery, and surgical approach. The surgical approach was independently categorized as the exploration of the brachial plexus (EBP) or nerve transfer without root exploration (NTwoRE). EBP was defined as exploring the brachial plexus in the supraclavicular fossa and applying a choice of coaptation procedures. NTwoRE included those sourcing donor nerves from, or entirely occurring outside of the plexus without exploring the root of the brachial plexus.

Results: Regression analysis of age at surgery 1985–2020 showed that age at BPBI surgery is rising (p < 0.05). Surgery was performed at a younger age in patients from Europe (7.06 ± 7.77 months) and Asia (7.58 ± 5.33 months) than those from North America (10.44 ± 5.01 months) and South America (14.71 ± 4.53 months) (p < 0.05). NTwoRE was more common in North America (37%) and least common in Europe (12%). Age at EBP was 7.2 ± 5.77 months, and age at NTwoRE was 15.85 ± 13.18 months (p < 0.05). The incidence of NTwoRE is increasing time.

Conclusions: Age at NBPP surgery is increasing over time. Regional differences exist in age at NBPP surgery. Approaches to NBPP surgery that avoid exploration of BP roots are becoming more popular. Age at EBP is lower than age at NTwoRE.

Purpose: Surgical treatments such as tendon transfers and muscle lengthening play a significant role in cerebral palsy management,but timing of upper extremity cerebral palsy surgery remains controversial. This study systematically reviews the current literature and investigates the correlation between age at surgery and follow-up time with surgical outcomes in pediatric upper extremity cerebral palsy patients.

Methods: A comprehensive search of PubMed, Cochrane, Web of Science, and CINAHL databases was performed from inception to July 2020 and articles were screened using PRISMA guidelines to include full-text, English papers. Data analysis was performed using itemized data points for age at surgery, follow-up length, and surgery outcomes, reported as changes in active forearm and wrist motion. A 3D linear model was performed, to analyze the relationship between age, follow-up length, and surgery outcomes.

Results: A total of 3,855 papers were identified using the search terms and a total of 8 studies with itemized patient data (n=126) were included in the study. The studies overall possessed moderate bias according to the ROBINS-I scale. Regression analysis showed that age is a significant predictor of change (|t| > 2) in active forearm supination (Estimate = -2.3465, Std. Error = 1.0938, t-value= -2.145) and wrist flexion (Estimate = -2.8474, Std. Error = 1.0771, t-value = -2.643) post-intervention, with older individuals showing lesser improvements. The duration of follow-up is a significant predictor of improvement in forearm supination (Estimate = 0.3664, Std. Error = 0.1797, t-value = 2.039) and wrist extension (Estimate = 0.7747, Std. Error = 0.2750, t-value = 2.817). In contrast, forearm pronation (Estimate = -0.23756, Std. Error = 0.09648, t-value = -2.462) and wrist flexion (Estimate = -0.4243, Std. Error=0.1859, t-value = -2.282) have a significant negative association with follow-up time.

Conclusion: These results suggest that there is significant correlation between the age and follow up after surgery with range of motion gains. Most notably, increased age at surgery had a significant negative correlation with select active range of motion postoperative outcomes. Future research should focus on identifying other factors that could affect results of surgical treatment in upper extremity.

Background: Efficient doctor-patient communication is essential for improving patient care. The impact of educational interventions on the communication skills of male and female students has not been systematically reviewed. The aim of this review is to identify interventions used to improve communication skills in medical curricula and investigate their effectiveness in improving the communication skills of male and female medical students.

Methods: A systematic review of the literature was conducted using the PRISMA guidelines. Inclusion criteria were as follows: used intervention strategies aiming to improve communication skills, participants were medical students, and studies were primary research studies, systematic reviews, or meta-analyses.

Results: 2913 articles were identified based on search terms. After title, abstract, and full-text review, 58 studies were included with interventions consisting of Training or Drama Courses, Curriculum-Integrated, Patient Learning Courses, and Community-Based Learning Courses. 69% of articles reported improved communication skills for both genders equally, 28% for women more than men, and 3% for men more than women. 16 of the 58 articles reported numerical data regarding communication skills pre-and post-intervention. Analysis revealed that post-intervention scores are significantly greater than pre-intervention scores for both male (p < 0.001) and female students (p < 0.001). While the post-test scores of male students were significantly lower than that of female students (p = 0.01), there is no significant difference between genders for the benefits, or difference between post-intervention and pre-intervention scores (p = 0.15), suggesting that both genders benefited equally.

Conclusion: Implementation of communication training into medical education leads to improvement in communication skills of medical students, irrespective of gender. No specific interventions benefitting male students have been identified from published literature, suggesting need of further studies to explore the phenomenon of gender gap in communication skills and how to minimize the differences between male and female students.

Introduction: While surgical literature exists on birth-related brachial plexus injury (BPI), there are not validated sources of information on BPI for patients, which can impact patient autonomy and decision-making. With YouTube as a popular source for patients to research diagnoses, this study aims to evaluate the quality of information regarding BPI and its treatment available on the platform.

Materials and Methods: BPI YouTube videos were screened independently by two reviewers. Videos were categorized by source: (1) academic, government, and non-profit organizations; (2) private practices, companies, and for-profit organizations; (3) independent users. Each video was evaluated for reliability, credibility, and quality using the modified DISCERN criteria (scale, 0–5), Journal of the American Medical Association (JAMA) criteria (scale, 0–4), and Global Quality Scale (GQS; scale, 1–5). Surgical treatment videos were analyzed by the senior author using a modified “treatment” DISCERN criteria (scale, 8–40). Non-English videos were excluded from this study. Analysis of variance tests were used to compare means.

Results: One hundred and fifteen videos were selected for final analysis. The mean modified DISCERN score was 3.26; JAMA was 2.31; GQS was 3.48. Videos were subdivided according to source. Group 1, 2, and 3 had 45, 24, and 46 videos, respectively. Modified DISCERN score was greater for Group 1 than Group 2 (3.58 vs. 3.04, p <.001) and Group 3 (3.58 vs. 3.07, p <.001). JAMA score was greater for Group 1 than Group 2 (2.63 vs 2.15, p =.041) and Group 3 (2.63 vs. 2.08, p =.002). GQS score was greater for Group 1 than Group 2 (3.93 vs. 3.31, p =.031) and Group 3 (3.93 vs. 3.13, p <.001). Of the 34 videos (44.7%) that mentioned treatment, the DISCERN score was 14.32.

Conclusion: The videos analyzed were found to have moderate reliability, credibility, and quality. The reliability of information regarding treatments for BPI was poor. Healthcare providers should supply additional information on treatment of BPI.

Background: Neonatal Brachial plexus palsy is an injury during delivery that can lead to loss of motor function and limited range of motion in patients due to damage of nerves in the brachial plexus. This scoping review aims to explore types of procedures performed and assess outcomes of forearm and elbow secondary surgery in pediatric patients.

Methods: Searches of PubMed, Cochrane, Cumulative Index to Nursing and Allied Health Literature, Web of Sciences, and Scopus were completed to obtain studies describing surgical treatment of elbow and forearm in pediatric patients with neonatal Brachial plexus palsy. 865 abstracts and titles were screened by two independent reviewers resulting in 295 full text papers; after applying of inclusion and exclusion criteria 18 articles were included. The level of evidence of this study is level IV.

Results: Ten main procedures were performed to regain function of the forearm and elbow in neonatal brachial plexus birth palsy patients. Procedures had different aims, with supination contracture (6) and elbow flexion restoration (5) being the most prevalent. The variance between preoperative and postoperative soft tissue and bony procedures outcomes decreased and showed improvement with respect to the aim of each procedure category. For soft tissue procedures, a statistically significant increase was found between preoperative and postoperative values for active elbow flexion, passive supination, and active supination. For bony procedures, there was a statistically significant decrease between preoperative and postoperative values of passive and active supination.

Conclusion: Overall, all procedures completed in the assessed articles of this study were successful in their aim. Bony procedures, specifically osteotomies, were found to have a wider range of results, whereas soft tissue procedures were found to be more consistent and reproducible with respect to their outcomes. Bony and soft tissue procedures were found vary in their aims and outcomes. This study indicates the need for further research to augment knowledge about indications and long-term benefits to each procedure.

Introduction: The objective of this study was to search existing literature on nerve reconstruction surgery in patients with obstetric brachial plexus palsy to determine whether treatment with supraclavicular exploration and nerve grafting produced better elbow flexion outcomes compared to intercostal nerve transfer.

Methods: This study was a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Individual Patient Data guidelines. A systematic search was conducted using multiple databases. An ordinal regression model was used to analyze the effect of using supraclavicular exploration and nerve grafting or intercostal nerve on elbow flexion with the two scores measured: elbow flexion Medical Research Council scores and Toronto active movements scale scores for elbow flexion.

Results: A final patient database from 6 published articles consisted of 83 supraclavicular exploration and nerve grafting patients (73 patients with Medical Research Council and 10 patients with Toronto score) and 7 published articles which consisted of 131 intercostal nerve patients (84 patients with Medical Research Council and 47 patients with Toronto scores). Patients who underwent supraclavicular exploration and nerve grafting presented with an average Medical Research Council score of 3.9 ± 0.72 and an average Toronto score of 6.2 ± 2.2. Patients who underwent intercostal nerve transfer presented with an average Medical Research Council score of 3.9 ± 0.71 and an average Toronto score of 6.4 ± 1.2. There was no statistical difference between supraclavicular exploration and nerve grafting and intercostal nerve transfer when utilizing Medical Research Council elbow flexion scores (ordinal regression: 0.3821, standard error: 0.4590, p = 0.2551) or Toronto Active Movement Scale score for elbow flexion (ordinal regression: 0.7154, standard error: 0.8487, p = 0.2188).

Conclusion: Regardless of surgical intervention utilized (supraclavicular exploration and nerve grafting or intercostal nerve transfers), patients had excellent outcomes for elbow flexion following obstetric brachial plexus palsy when utilizing Medical Research Council or Toronto scores for elbow flexion. The difference between these scores was not statistically significant.

Type of study/Level of evidence: Therapeutic Study: Investigating the Result of Treatment/level III.

Introduction: Surgical management is recommended in patients with severe neonatal brachial plexus palsy (NBPP) within the first 6 months of age to regain best possible function. Rehabilitation post-surgery remains relatively unexplored. This is a scoping review that explores, which rehabilitation modalities exist and how they vary for different microsurgical approaches in NBPP.

Materials and Methods: A systematic search was conducted to include articles about upper trunk obstetric brachial plexus nerve microsurgery in pediatric patients that made mention of rehabilitation protocols. The aims of rehabilitation modalities varied and were grouped: “passive” movement to prevent joint contracture or stiffness, “active” or task-oriented movement to improve motor function, or “providing initial motor recovery”. Surgical approach was described as either exploration of the brachial plexus (EBP) or nerve transfer without root exploration (NTwoRE). Technique was categorized into transfers and non-transfers.

Results: Thirty-six full-text articles were included. Initiation of rehabilitation was 22.26 days post-surgery. Twenty-eight studies were EBP, and six were NTwoRE. Of studies classifiable by aims, nine were “passive”, nine were “active”, and five were “providing initial motor recovery”. Only 27.7% of EBP studies mentioned active therapy, while 75.0% of NTwoRE studies mentioned active therapy. The average age of patients in the EBP procedure category was 7.70 months, and NTwoRE was 17.76 months. Within transfers, the spinal accessory to suprascapular group was more likely to describe an active shoulder exercise therapy, whereas contralateral C7 group was more likely to describe “initial motor recovery”, especially through the use of electrostimulation. All articles on electrostimulation recommended 15–20-minute daily treatment.

Conclusion: Information on rehabilitation is limited post-nerve surgery in NBPP. However, when mentioned, the aims of these therapies vary with respect to surgical approach and technique. The type of therapy to employ may be a multifaceted decision, involving factors such as patient age, initial deformity, and goals of the care team.

Introduction: Brachial plexus birth injury (BPBI) has an incidence of 0.9 per 1,000 live births in the population. Techniques for repair classically include supraclavicular exploration and nerve grafting (SENG) and more recently nerve transfer, namely of the spinal accessory nerve (SAN) to the suprascapular nerve (SSN) to improve functional outcomes such as glenohumeral abduction and external rotation. This systematic review was conducted to evaluate whether spinal accessory nerve transfer produced significantly better outcomes for shoulder abduction in BPBI.

Methods: A search was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analysis Individual Patient Data guidelines. Standardized comparisons were made using the Mallet Score for shoulder abduction.

Results: 10 full-text articles with itemized patient outcome measures were selected. 110 patients were identified with 51 patients in the SENG group and 59 patients in the SAN transfer group. The mean shoulder abduction Mallet score in the SENG group was 3.50 ± 0.84, while the mean Mallet score in the SAN transfer group was 3.58 ± 0.77, which displayed no significant differences (p = 0.9012). There was no significant relationship between the age at time of surgery and post-operative Mallet scores for shoulder abduction after SENG (p = 0.3720).

Discussion: Our systematic review found that there was no difference observed in post-operative outcomes of shoulder abduction when comparing SAN transfer and nerve grafting. Continued support for nerve grafting lies in the argument that it incorporates the patient's native neuroanatomy and allows for sensory reinnervation.

BACKGROUND AND AIMS: Evidence suggests that female surgeons achieve comparable or even more favorable outcomes than male surgeons. It is currently unclear what factors contribute to these potential differences. Possible explanations might be differences in personality traits, communication style, attitude, and risk-taking behavior. This cross-sectional study aimed to examine disparities in personality traits between male and female general surgeons in Sweden.

METHODS: The research was conducted as a cross-sectional study of personality traits. Between August 29, 2022, and December 15, 2023, Swedish specialists in general surgery were invited to participate in an online survey. The survey, assessed with the Big Five Inventory, collected information on self-reported surgeon gender, years in practice, employment data, and differences in personality traits.

RESULTS: The analysis encompassed responses from 223 Swedish general surgeons: 121 (54%) males and 102 (46%) females. In contrast to female surgeons, male surgeons were older and had longer surgical experience. A higher proportion of male surgeons were employed in rural hospitals. Higher mean scores were observed in all personality traits among female surgeons. The adjusted analysis showed significantly higher scores for conscientiousness (p < 0.001), extraversion (p < 0.001), agreeableness (p = 0.006), and neuroticism (p < 0.001); however, no such change was observed for openness.

CONCLUSION: This cross-sectional study demonstrates that Swedish female and male surgeons differ in personality traits. The implications of these results could lead to a deeper understanding of the variations in surgical outcomes based on the gender of the surgeon.

Background: Neurogenic Thoracic Outlet Syndrome (nTOS) is a rare pathology caused by dynamic conditions or compression of neurovascular structures in the thoracic outlet region. nTOS can be difficult to diagnose due to nonspecific symptoms and magnetic resonance imaging (MRI) techniques are increasingly used to aid the diagnosis and surgical planning. This scoping systematic review explores how MRI is used for diagnosing nTOS and summarizes details of published MRI protocols.

Methods: A systematic screening of PubMed, Cochrane, Web of Science, and CINAHL databases using PRISMA-IPD guidelines was conducted in September 2022 to include full-text English papers on MRI and nTOS. Inclusion criteria involved studies describing MRI protocols for the diagnosis of TOS, with a focus on the imaging sequences and protocols.

Results: 6289 papers were screened to include 28 papers containing details of MRI protocols. The details of MRI protocols in the analyzed articles were incomplete in all studies. Most authors used 1.5T systems and included T1 and T2-weighted sequences. Most studies applied fat suppression, mainly with STIR. Positioning of the arm differed between studies, including neutral, hyperabducted and abducted and externally rotated positions.

Conclusion: Our review highlights a prevalent lack of detailed MRI protocol documentation for brachial plexus. Authors primarily rely on conventional 1.5T systems, employing standard T1 and T2-weighted sequences. The adoption of novel MRI sequences is notably lacking, and fat suppression techniques predominantly adhere to older methods as STIR. There is a clear imperative for authors to provide more comprehensive reporting of the MRI protocols utilized in their studies, ultimately enhancing comparability and clinical applicability. Establishing clear protocol reporting guidelines is crucial to allow for comparison between studies.
