Background: The Calgary Kids' Hand Rule (CKHR) is a clinical prediction rule intended to guide referral decisions for pediatric hand fractures presenting to the emergency department, identifying "complex" fractures that require surgical referral and optimizing care through better matching of patients' needs to provider expertise. The objective of this study was to externally validate the CKHR in two different tertiary pediatric hospitals in Canada. Methods: We partnered with British Columbia Children's Hospital (BCCH) and the Children's Hospital of Eastern Ontario (CHEO) to externally validate the CKHR using data from retrospective cohorts of pediatric hand fractures (via electronic medical record and x-ray review). Model performance was evaluated at each site using sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and the C-statistic. Results: A total of 954 hand fractures were included in the analysis (524 at BCCH and 430 at CHEO. At BCCH, the CKHR had a sensitivity of 91.1% (133 predicted complex out of 146 total complex fractures), specificity of 71.4% (269 predicted simple out of 377 total simple fractures), and C-statistic of .81, 95% CI [0.78-0.84]. At CHEO, the CKHR had a sensitivity of 98.3%, specificity of 30.2%, and C-statistic of .64, 95% CI [0.61-0.67]. Conclusion: The CKHR performed well at two different tertiary care centres with high sensitivity, supporting its ability to facilitate hand fracture triage in other populations without further modification. This work should be followed by rigorous implementation analysis to determine its impact on patient care.

Introduction: Lipohypertrophy is the most reported cutaneous complication of insulin injection. In cases refractory to conservative management, liposuction has been proposed as a treatment. This review aims to evaluate the use of liposuction for the treatment of insulin-induced lipohypertrophy. Methods: A literature search was conducted to identify case reports and case series that met inclusion criteria. Demographic, procedural, and outcome data were collected and summarized. Results: Ten case reports and 1 case series met eligibility criteria; 18 patients (16 female) with a mean age of 31 years were included for analysis. The primary indication for lipectomy was cosmetic (100%), followed by pain (16.7%), injection difficulty (16.7%), and poor glycemic control (11.1%). Ten patients (55.6%) underwent general anesthesia for their procedure, while 8 (44.4%) received local anesthesia. Thighs (53.8%) were the most common anatomical site of liposuction, followed by the upper arm (19.2%), abdomen (15.4%), buttocks (7.7%), and the flank (3.8%). The median volume of adipose tissue removed per site was 300 mL (range: 25-600 mL), while the total volume per patient was 910.8 mL (range: 200-2900 mL). The average postoperative follow-up time was 5.3 months (range: 2-10 months). Three patients reported postoperative improvement of glycemic control; 100% of patients were satisfied with their procedure. Small surface irregularities were reported in 2 patients. Conclusion: Although future investigations are warranted, these results may indicate that the use of liposuction to treat insulin-induced lipohypertrophy is a safe and effective procedure that achieves improved cosmetics with high patient satisfaction and enhanced glycemic control.

Background: Breast implants were first introduced in the 1960s and have long been used for augmentation and reconstructive breast surgery. More recently, fat grafting for breast augmentation has gained popularity due to the 'natural' outcome and lack of implant-related complications. The aim of this study was to conduct a systematic review and meta-analysis comparing patient-related outcome measures between fat grafting and implant-based primary augmentation using the validated BREAST-Q questionnaire. Methods: A systematic review of the literature according to the PRISMA guidelines was conducted in PubMed®, Cochrane Library®, EMBASE®, MEDLINE®, and Scopus® databases. Papers were screened by two independent blinded reviewers. Quality was assessed using MINORS criteria. Results: Fourteen studies were included in the meta-analysis representing a total of 81 fat grafting augmentations and 1535 implant augmentations. The average overall patient satisfaction mean post-operative scores were 13.0 points higher in the implant group based on meta-regression (95% CI: 2.4-23.5; P = .016). There was no statistical difference in reported post-operative sexual well-being, psychosocial well-being, or physical well-being BREAST-Q scores. Conclusion: Although implant-based augmentation resulted in higher post-operative overall satisfaction scores, fat grafting remains a highly desirable alternative for augmentation in the right patient. This meta-analysis strongly highlights that careful patient selection and evaluation of patient goals must be assessed when selecting an augmentation method.

Background: Rectovaginal fistula (RVF) remains a complex complication following gender-affirming vaginoplasty. This review aims to evaluate RVF repair techniques and outcomes following vaginoplasty. Methods: A systematic review was performed per PRISMA guidelines. Ovid MEDLINE, Ovid EMBASE, Cochrane, and Web of Science were queried for records pertaining to RVF repair following vaginoplasty. Study characteristics, operative details, and demographics were collected. Outcomes included RVF repair method, recurrence rate, and complications. Results: Among 282 screened citations, 17 articles representing 41 patients were included. Rectovaginal fistula repair methods identified included 4 conservative management approaches (n = 12 patients), primary closure with or without fistulectomy and ostomy (n = 22), 10 reconstructive surgical techniques (n = 18). The most common reconstructive techniques were V-Y full-thickness advancement with rectal flap (n = 5) and infragluteal fasciocutaneous flap (n = 4). Median time to recurrence was 6 months (interquartile range 7.5). Reported RVF repair complications included RVF recurrence (n = 5, 14.7%) and wound complication or dehiscence (n = 2, 5.88%). Three cases of RVF recurred after primary closure with or without fistulectomy and ostomy, while 2 cases of recurrence followed reconstruction. Conclusion: There remains a high level of variability in the approach to RVF repair following vaginoplasty. Reconstructive surgical techniques may be a more optimal solution without necessitating ostomies, but this decision must be considered in the context of RVF location, individual patient expectations, and clinical presentation.

Introduction: Antimicrobial prophylaxis is crucial in reducing surgical site infections (SSIs). First-generation cephalosporins are commonly first line, but issues arise when patients report a penicillin allergy. Although up to 10% of Americans report a penicillin allergy, up to 95% are not truly allergic. Even patients with true penicillin allergy likely tolerate cephalosporins due to low cross-reactivity. Nevertheless, providers are less likely to prescribe cefazolin for these patients, increasing the risk of SSI. We seek to characterize the pattern of perioperative antibiotic use and rate of reaction in plastic surgery patients who endorse a penicillin allergy. Method: This was a single-center retrospective chart review of adults who received body contouring plastic surgery from January 1, 2021 to December 31, 2021. The presence of reported penicillin allergy and administration of cefazolin versus alternative agent were evaluated, and the outcome was measured in number of anaphylactic reactions and SSI events. Results: The study included 457 patients in total; 437 (96%) were female; 106 (23%) had listed allergy to penicillin, cephalosporin, or both - 17 (16%) were listed as having anaphylaxis to penicillin, 62 (58.5%) endorsed a nonanaphylactic allergic reaction to penicillin, 8 (7.5%) endorsed an allergy without a documented reaction to penicillin, and 19 (18%) reported a prior cephalosporin allergy. All patients with a beta-lactam allergy who received cefazolin perioperatively did not have any anaphylaxis events. Three patients who received clindamycin and 1 patient who received cefazolin developed SSI postoperatively. Conclusion: Cephalosporins should be the first line for appropriate patients with a penicillin allergy, as alternative agents have increased SSI risk.

Background: There is a lack of previous studies investigating oncoplastic practice trends for breast reconstruction in Canada, particularly from the plastic surgeon perspective. Given the rising popularity of oncoplastic techniques, this study aimed to identify current practice trends for breast and plastic surgeons in Canada. Methods: A cross-sectional survey study of breast and plastic surgeons performing oncoplastic surgery across Canada was conducted. Results: Ninety-five surgeons were invited to complete the survey, with 58 respondents (response rate 61%), of which 29 (50.0%) were breast surgeons and 29 (50.0%) were plastic surgeons. Compared to plastic surgeons, breast surgeons performed significantly more level 1 surgeries (27.6 vs 3.45%, P < .001). Plastic surgeons performed more level 2 (37.9% vs 13.8%, P = .0475) and level 3 (31.4% vs 10.3%, P = .00814) surgeries. Breast surgeons identified significant perceived barriers including unfamiliarity with techniques (P = .00513), adjuvant therapy delays (P = .00612), lack of plastic surgery support (P < .001), lack of radiation oncology support (P = .0485), increased OR time (P < .001), lack of OHIP billing codes (P < .001), and post-operative complication management (P = .0372). Breast surgeon comfort with oncoplastic techniques was not correlated with practice duration (R-square = .037, P-value = .853). Breast surgeon comfort with contralateral surgery was not correlated with practice setting (R-square = .071, P-value = .632). Conclusions: Breast surgeons perceive a lack of training, a lack of support from plastic surgery, concerns regarding appropriate financial remuneration, and worries of increased OR time as barriers in oncoplastic surgery. Collaboration between general breast surgery and plastic surgery is needed for improving training options for oncoplastic surgery in Canada and for providing excellent breast cancer care overall.

Introduction: The goal of this study is to determine factors associated with acceptance into Canadian plastic surgery (PS) residency programs by Saudi Arabian Medical Graduates. Methods: This is a cross-sectional study targeting eligible Saudi Arabian applicants to any Canadian PS residency program between 2017 and 2022. Collected data included demographics, education/licensure, electives in Canada, and letter of reference. The 2 main outcomes analyzed were "invited for an interview" and "offered a residency position." Results: We reviewed 52 applications. Of these, 18 applicants received an invitation for an interview and 8 were offered a residency training position. Significant variables associated with receiving an invitation for an interview were completing an elective in Canada (P = .016), having a master's degree (P = .012), and completion of an English test (P = .032). The variables most likely to influence receiving a residency position offer are completion of elective training in Canada (P = .004) and receiving a letter of reference from a Canadian plastic surgeon (95% CI: 0.77 to 76.69: OR: 8.90). Conclusion: Completion of an elective rotation in Canada and obtaining Canadian letters of reference were found to be the most important factors for Saudi Arabian physician applicants to be accepted into a Canadian PS residency program. Other factors that were less critical but improved their chances of being considered include completion of an English assessment test and having a master's degree. This study offers valuable guidance for any Saudi Arabian candidates interested in PS residency in Canada and may aid Canadian programs in their assessment of potential residents.

Introduction: Peripheral nerve injury (PNI) is a complex, debilitating condition that is increasingly being treated in interdisciplinary clinics. Patients see peripheral nerve surgeons, neurologists, physiatrists, and electrodiagnostic technicians in a single encounter. No studies have evaluated patient experience within this unique interdisciplinary care model. This study aims to assess patients' perceptions of the effectiveness of delivery of care and health care information in an interdisciplinary PNI clinic. Methods: A cross-sectional mixed-methods study was conducted using a 23-question survey that was by a lived-experience partner (an individual who had a brachial plexus injury) in research who helped design the survey. Participants attended an interdisciplinary clinic for PNI 1-2 days prior to taking the survey. The survey included 5-point Likert scales for measuring patient understanding and qualitative questions that were categorized into themes, using conventional content analysis. Results: Of the 20 participants, 65% were male, 35% were female and the mean age was 42.6 ± 17.8. Median scores of 4 were obtained for the patient understanding of the testing purposes, test results, nerve recovery after PNI, and surgical decision-making (full understanding = 5). On improving the clinical experience, 58% indicated no improvements were necessary, while 17% indicated the clinic felt rushed or overwhelming. When asked about positive aspects of their clinical experience, 64% appreciated the team approach to care, 27% valued the informative nature of the clinic, and 27% appreciated the progress they felt when providers at the clinic performed nerve testing. Conclusions: The results demonstrate that patients with PNI have overall positive perceptions of the delivery of care and information in an interdisciplinary PNI clinic. These results provide new insight into how interdisciplinary care may be beneficial to PNI patients based on the perceived effectiveness of knowledge translation.

Background: Gaps remain in surgical education regarding the representation of skin tone diversity. To improve equity and prevent misdiagnosis leading to worsened health outcomes, efforts must be made to ensure educational photographs are representative of the diverse patient populations plastic surgery residents will be treated in their future practices. Methods: Four study investigators examined 96 h of recorded lecture seminars from a Canadian plastic surgery resident education curriculum from May 2020 to December 2021. Using Fitzpatrick skin type to codify skin tone, photographic images were individually classified and compared. Program lecturers and residents were invited to participate in an online anonymized survey to explore related perceptions of the curricula. Results: A total of 1990 images were included for analysis. Of these, 83.2% were Fitzpatrick types I to III, 13.1% were Fitzpatrick types IV to V, and 3.7% were Fitzpatrick type VI. There was a statistically greater proportion of Fitzpatrick I to III compared to types IV to V (P < .01), and type VI (P < .01). Fleiss' Kappa was calculated to be 0.896, representing near-perfect agreement. In the survey, 61% (14/22) of faculty respondents believe they include enough diversity in their photographs, however, 46% (4 of 9) of resident respondents would like to see more diversity in lecturers' photographs. Conclusions: There is an underrepresentation of medium (Fitzpatrick types IV-V) and dark (Fitzpatrick VI) images in plastic surgery resident educational images. Providing a curriculum that represents diverse patient populations is crucial to enabling competency and equity of care, particularly in a highly visual field. Incorporating skin tone diversity into educational curricula should be a priority for all plastic surgery programs.

Introduction: Microsurgical learning is a difficult and stressful process, requiring self-control to achieve relaxation. The purpose of this study is to evaluate peripheral and central nervous system relaxation during microsurgical training. Methods: This cohort study included ten medical students with no previous experience in microsurgery. The somatic peripheral nervous system was evaluated by the force applied to a custom-designed microsurgical needle holder. The autonomic peripheral nervous system was assessed by a heart rate monitor. Central nervous system relaxation was evaluated by the State and Trait Anxiety Inventory scores. The quality of the anastomosis was graded by the Microsurgical Anastomosis Rating Scale (MARS10). These data were compared to a group of 5 senior microsurgeons who underwent a single assessment. Results: The time to complete the anastomosis and the force decreased significantly with training after only 2 weeks (P < .05). After 4 weeks of training, no statistical difference was observed between students and experts regarding force while the time of suture was still significantly different at 30 days (P = .001). The maximum heart rate decreased significantly at 2 weeks (P = .01). Anxiety scores decreased significantly between days 1 and 15 (P = .002 and P = .036). The MARS10 score demonstrates that the quality of the suture increases significantly during the first 15 days (P = .006). Conclusion: Peripheral and central nervous system relaxation as well as the quality of the microsurgical anastomosis increase significantly after only 15 days of learning. The force-sensing microsurgical needle holder offers a new tool for the evaluation of relaxation and can function as a learning aid.
