- Abstract
Background Mini C-arm units are compact, mobile, fluoroscopic imaging systems designed for real-time imaging of the extremities. They deliver the lowest possible radiation exposure to the patient and physician while minimizing operator effort and inconvenience.Methods A retrospective chart review was undertaken for consecutive metacarpal fractures requiring internal fixation treated in the minor surgery centre before (n=100) and after (n=100) the introduction of the mini C-arm. Open versus closed approach, procedure time and total operating room time were recorded.Results Before the introduction of the mini C-arm, the percutaneous rate was 48% and the average procedure and total operating room times were 55 min and 102 min, respectively. After mini C-arm implementation, the percutaneous rate increased to 59% and the average procedure and total times were 36 min and 78 min, respectively.Conclusions The use of a mini C-arm increased the rate of successful closed reduction internal fixation and reduced the procedure time for metacarpal fractures treated in the minor surgery area.

- Abstract
Background: Orofacial clefts (OFCs) include cleft palate (CP), cleft lip (CL), and cleft lip with cleft palate (CLP) and require multidisciplinary healthcare services. Alberta, Canada has a publicly funded, universal access healthcare system. This study determined publicly funded healthcare costs for children with an OFC and compared these costs to children without congenital anomalies., Methods: This retrospective population-based cohort analysis used the Alberta Congenital Anomalies Surveillance System to identify children born between 2002 and 2018 with an isolated OFC. They were matched 1:1 to a reference cohort based on sex and year of birth. The study population included 1614 children, from birth to 17 years of age linked to administrative databases to estimate annual inpatient and outpatient costs. Average annual all-cause costs were compared using two-sample independent t tests., Results: The mean total cleft-related costs per patient were highest for children with CLP ($74,138 CAD, standard deviation (SD) $43,447 CAD), followed by CP ($53,062 CAD, SD $74,366 CAD), and CL ($35,288 CAD, SD $49,720 CAD). The mean total all-cause costs per child were statistically significantly higher (p < .001) in children with an OFC ($56,305 CAD, SD $57,744 CAD) compared to children without a congenital anomaly ($18,600 CAD, SD $61,300 CAD)., Conclusions: Despite public health strategies to mitigate risk factors, the trend for OFCs has remained stable in Alberta, Canada for over 20 years. The costs reported are useful to other jurisdictions for comparison, and to families, healthcare professionals, service planners, and policy makers., (© 2024 Wiley Periodicals LLC.)

- Abstract
Purpose: Pediatric hand fractures are frequent presentations to the emergency department. This study set out to evaluate the epidemiology, management, and outcomes, where care was imparted and by whom, and offer resource utilization suggestions regarding pediatric fractures presenting to a Canadian pediatric hospital. Methods: Records of patients from 0 to 18 years of age who presented to the British Columbia Children's Hospital Emergency Department between November 1, 2016, and January 31, 2021, with metacarpal or phalangeal fractures were analyzed. Results: A total of 524 hand fractures were identified in 499 patients. Over 60% of fractures occurred in boys. The number of fractures peaked at the age of 11 years for girls and 12 years for boys. Open fractures accounted for only 4.0% of all fractures. Approximately 40% of fractures were epiphyseal growth plate fractures, with Salter-Harris II fractures being the most common diagnosis overall. Management was primarily nonsurgical, with 75% of fractures managed with immobilization alone and 23% of fractures managed with bedside closed reduction and immobilization. Of the fractures requiring closed reduction, the majority were performed by the emergency physician with a success rate of 82%. Only 2.3% of all fractures required surgery. Conclusions: Hand fractures are common pediatric injuries and make up a large proportion of emergency room visits. The majority of fractures do not require formal surgery and are well managed with immobilization alone or closed reduction by an emergency room physician and immobilization. Nonsurgical treatment offers very encouraging outcomes. A certain percentage of these simple fractures would likely benefit from primary care management alone and not require specialist intervention., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© 2022 The Author(s).)

- Abstract
Introduction: Pediatric hand fractures are common and routinely referred to surgeons, yet most heal well without surgical intervention. This trend inspired the development of the Calgary Kids' Hand Rule (CKHR), a clinical prediction rule designed to predict "complex" fractures that require surgical referral. The CKHR was adapted into a checklist whereby the presence of any 1 of 6 clinically or radiologically identifiable fracture characteristics predicts a complex fracture. The aim of this study was to assess the accuracy of the CKHR in a prospective sample of children with hand fractures. Methods: Physicians were asked to complete the CKHR checklist when referring pediatric patients (< 18 years) to hand surgeons at a Canadian pediatric hospital (April 2019-September 2020). Completed checklists represented predicted outcomes and were compared to observed outcomes (determined via chart review). Predictive accuracy (primary outcome) was evaluated based on sensitivity and specificity. Secondary outcomes were interrater reliability between referring physicians and surgeons, and survey assessment of CKHR user satisfaction. Results: In total 365 fractures were included, with only 16 requiring surgical intervention. Overall performance of the CKHR was good with 84% sensitivity and 71% specificity. Percent agreement between referring physicians and surgeons ranged from 84.1% to 96.3% on individual predictors, with 78.1% agreement on the presence of any predictors. Survey results showed general user satisfaction but also identified areas for improvement. Conclusion: This study posits the CKHR as an accurate and clinically useful prediction rule and highlights the importance of education for its effective use and eventual scale and spread., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© 2022 The Author(s).)

- Abstract
We recently highlighted shortcomings in the care of pediatric hand fractures in our local context. The Calgary Kids' Hand Rule (CKHR) was developed to predict hand fractures that require referral to a hand surgeon. The aims of this study were to identify barriers to a new care pathway for pediatric hand fractures, based on the CKHR and to generate tailored strategies to support its implementation., Methods: We performed a conventional content analysis of transcripts from four focus groups (parents, emergency/urgent care physicians, plastic surgeons, and hand therapists) to identify relevant concepts (facilitators and barriers). These concepts were mapped to two frameworks. Generic strategies to address the barriers were identified, and further discussions with key stakeholders resulted in tailored strategies for implementation., Results: Five facilitators to implementation of a CKHR-based hand fracture care pathway included established rapport between hand therapists and surgeons, potential for more streamlined care, agreement on identifying another care provider, positive perceptions of hand therapist expertise, and opportunity for patient education. Two individual barriers were concern for poor outcomes and trust. Three systemic barriers were awareness and usability, referral process, and cost and resources. Strategies to address these barriers include pilot-testing of the new care pathway, ensuring closed loop communication, multiple knowledge translation activities, integration of CKHR into the clinical information system, coordinating care and development of parent handouts., Conclusion: Mapping barriers to established implementation frameworks has informed tailored implementation strategies, bringing us one step closer to successfully implementing a new pediatric hand fracture pathway., (Copyright © 2023 The Authors.

- Abstract
Pediatric hand fractures are common, and many are referred to hand surgeons despite less than 10% of referrals requiring surgical intervention. We explored healthcare provider and parent perspectives to inform a new care pathway., Methods: We conducted a qualitative descriptive study using virtual focus groups. Emergency physicians, hand therapists, plastic surgeons, and parents of children treated for hand fractures were asked to discuss their experiences with existing care for pediatric hand fractures, and perceptions surrounding the implementation of a new care pathway. Data were analyzed using directed content analysis with an inductive approach., Results: Four focus groups included 24 participants: 18 healthcare providers and six parents. Four themes were identified: educating parents throughout the hand fracture journey, streamlining the referral process for simple hand fractures, identifying the most appropriate care provider for simple hand fractures, and maintaining strong multidisciplinary connections to facilitate care. Participants described gaps in the current care, including a need to better inform parents, and elucidated the motivations behind emergency medicine physicians' existing referral practices. Participants also generally agreed on the need for more efficient management of simple hand fractures that do not require surgical care. Healthcare providers believed the strong preexisting relationship between surgeons and hand therapists would facilitate the changes brought forward by the new care pathway., Conclusion: These findings highlighted shortcomings of existing care for pediatric hand fractures and will inform the co-development and implementation of a new care pathway to enable more efficient management while preserving good patient outcomes., (Copyright © 2023 The Authors.

- Abstract
Introduction: Current published long-term provincial or territorial congenital anomaly data are lacking for Canada. We report on prevalence (per 1000 total births) and trends in 1997-2019, in Alberta, Canada, for selected congenital anomalies. Associated risk factors are also discussed., Methods: We used data from the Alberta Congenital Anomalies Surveillance System (ACASS) to calculate the prevalence and perform chi-square linear trend analyses., Results: From 1997 to 2019, the overall prevalence of neural tube defects was stable, at 0.74 per 1000 total births. The same was true for spina bifida (0.38), orofacial clefts (1.99), more severe CHDs (transposition of the great arteries, 0.38; tetralogy of Fallot, 0.33; and hypoplastic left heart syndrome, 0.32); and gastroschisis (0.38). Anencephaly, cleft palate and anorectal malformation significantly decreased with a prevalence of 0.23, 0.75 and 0.54 per 1000 total births, respectively. Significantly increasing trends were reported for anotia/microtia (0.24), limb reduction anomalies (0.73), omphalocele (0.36) and Down syndrome (2.21) and for hypospadias and undescended testes (4.68 and 5.29, respectively, per 1000 male births)., Conclusion: Congenital anomalies are an important public health concern with significant social and societal costs. Surveillance data gathered by ACASS for over 40 years can be used for planning and policy decisions and the evaluation of prevention strategies. Contributing genetic and environmental factors are discussed as is the need for continued surveillance and research., Competing Interests: The authors declare no conflicts of interest.

- Abstract
Objective: To evaluate the development process and clinical impact of implementing a standardized perioperative clinical care pathway for cleft palate repair., Design: Medical records of patients undergoing primary cleft palate repair prior to pathway implementation were retrospectively reviewed as a historical control group (N = 40). The historical cohort was compared to a prospectively collected group of patients who were treated according to the pathway (N = 40)., Patients: Healthy, nonsyndromic infants undergoing primary cleft palate repair at a tertiary care pediatric hospital., Interventions: A novel, standardized pathway was created through an iterative process, combining literature review with expert opinion and discussions with institutional stakeholders. The pathway integrated multimodal analgesia throughout the perioperative course and included intraoperative bilateral maxillary nerve blocks. Perioperative protocols for preoperative fasting, case timing, antiemetics, intravenous fluid management, and postoperative diet advancement were standardized., Main Outcome Measures: Primary outcomes include: (1) length of hospital stay, (2) cumulative opioid consumption, (3) oral intake postoperatively., Results: Patients treated according to the pathway had shorter mean length of stay (31 vs 57 hours, P < .001), decreased cumulative morphine consumption (77 vs 727 μg/kg, P < .001), shorter time to initiate oral intake (9.3 vs 22 hours, P = .01), and greater volume of oral intake in first 24 hours postoperatively (379 vs 171 mL, P < .001). There were no differences in total anesthesia time, total surgical time, or complication rates between the control and treatment groups., Conclusions: Implementation of a standardized perioperative clinical care pathway for primary cleft palate repair is safe, feasible, and associated with reduced length of stay, reduced opioid consumption, and improved oral intake postoperatively.

- Abstract
Background: Pediatric hand fractures are common, and most can be managed by a period of immobilization. However, it remains challenging to identify those more complex fractures requiring the expertise of a hand surgeon to ensure a good outcome. The purpose of this study was to develop a prediction model for identification of complex pediatric hand fractures requiring care by a hand surgeon., Methods: A 2-year retrospective cohort study of consecutively referred pediatric (<18 years) hand fracture patients was used to derive and internally validate a prediction model for identification of complex fractures requiring the expertise of a hand surgeon. These complex fractures were defined as those that required surgery, closed reduction, or four or more appointments with a hand surgeon. The model, derived by multivariable logistic regression analysis, was internally validated using bootstrapping and then translated into a risk index., Results: Of 1170 fractures, 416 (35.6%) met criteria for a complex fracture. Multivariable regression analysis identified six significant predictors of complex fracture: open fracture, rotational deformity, angulation, condylar involvement, dislocation or subluxation, and displacement. Internal validation demonstrated good performance of the model (C-statistic = 0.88, calibration curve p = 0.935). A threshold of ≥1 point (ie, any one of the predictors) resulted in a simple, easy-to-use tool with 96.4% sensitivity and 45.5% specificity., Conclusions: A high-performing and clinically useful decision support tool was developed for emergency and urgent care physicians providing initial assessment for children with hand fractures. This tool will provide the basis for development of a clinical care pathway for pediatric hand fractures., Competing Interests: Disclosure: All the authors have no financial interest in relation to the content of this article., (Copyright © 2021 The Authors.

- Abstract
Few studies have evaluated vascularized nerve grafts (VNGs) for facial nerve (CNVII) reconstruction. We sought to evaluate long-term outcomes for CNVII recovery following reconstruction with VNGs. A retrospective review of all patients at a tertiary centre who underwent radical parotidectomy and immediate CNVII reconstruction with VNGs was performed (January 2009-December 2019). Preoperative demographics, perioperative factors (flap type, source of VNGs), and postoperative factors [complications, adjuvant therapy, revisionary procedures, length of follow-up, and CNVII function via the House-Brackmann scale (HB)] were collected. Data were summarized qualitatively. Twelve patients (M
age = 53 ± 18 years) with a mean follow-up of 33 (± 23) months were included. Six patients underwent reconstruction with a radial forearm flap and dorsal sensory branches of the radial nerve. Six patients underwent reconstruction with an anterolateral thigh flap and only deep motor branches of the femoral nerve to the vastus lateralis (n = 4) or combined with the lateral femoral cutaneous nerve (n = 2). Two patients regained nearly normal function (HB = 2). Eight patients regained at least resting symmetry (HB = 3 for n = 7; HB = 4 for n = 1). One patient regained a flicker of movement (HB = 5). One patient did not regain function (HB = 6). Six patients had static revision procedures to improve symmetry. Five patients had disease recurrence; 3 died from their disease. VNGs offer a practical and viable addition to the CNVII reconstruction strategy, and result in good functional recovery with acceptable donor site deficits. The associated adipofascial component of these flaps can also augment the soft tissue defect left after tumor ablation., (Copyright © 2021 The Authors.

- Abstract
Background: Some women with breast implants express concern about the safety of implants, fearing the possibility of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) and breast implant-related illness., Methods: A qualitative analysis was performed to examine the perceived challenges, barriers, and worries experienced by these women. Convenience sampling was used to elicit responses from members of Canadian BIA-ALCL Facebook advocacy groups. Three independent coders read and reread the transcripts, using thematic analysis to identify emerging themes., Results: Sixty-four women answered questions posed by the president of the Canadian Society of Plastic Surgeons regarding concerns about their breast implants. Five themes were identified: informing, listening, acknowledging, clarifying, and moving forward. Patients desire improved communication about possible risks before implantation and as new information becomes available (informing), sincere listening to their concerns (listening), acknowledgement that these disease entities may be real and have psychosocial/physical impact on patients (acknowledging), clarification of implant-related problems and their treatment (clarifying), and improved processes for monitoring and treatment of patients with identified problems (moving forward). Consideration of these themes in the context of the five domains of trust theory (i.e., fidelity, competence, honesty, confidentiality, and global trust) suggests significant breakdown in the doctor-patient relationship for a subset of concerned women., Conclusions: Concerns related to BIA-ALCL and breast implant-related illnesses have undermined some women's trust in plastic surgeons. Consideration of these five themes and their impact on the five domains of trust can guide strategies for reestablishing patients' trust in the plastic surgery community., Competing Interests: Disclosure:The authors have no financial disclosures or conflicts of interest to report., (Copyright © 2020 by the American Society of Plastic Surgeons.)

- Abstract
Purpose: Deep phenotyping is an emerging trend in precision medicine for genetic disease. The shape of the face is affected in 30-40% of known genetic syndromes. Here, we determine whether syndromes can be diagnosed from 3D images of human faces., Methods: We analyzed variation in three-dimensional (3D) facial images of 7057 subjects: 3327 with 396 different syndromes, 727 of their relatives, and 3003 unrelated, unaffected subjects. We developed and tested machine learning and parametric approaches to automated syndrome diagnosis using 3D facial images., Results: Unrelated, unaffected subjects were correctly classified with 96% accuracy. Considering both syndromic and unrelated, unaffected subjects together, balanced accuracy was 73% and mean sensitivity 49%. Excluding unrelated, unaffected subjects substantially improved both balanced accuracy (78.1%) and sensitivity (56.9%) of syndrome diagnosis. The best predictors of classification accuracy were phenotypic severity and facial distinctiveness of syndromes. Surprisingly, unaffected relatives of syndromic subjects were frequently classified as syndromic, often to the syndrome of their affected relative., Conclusion: Deep phenotyping by quantitative 3D facial imaging has considerable potential to facilitate syndrome diagnosis. Furthermore, 3D facial imaging of "unaffected" relatives may identify unrecognized cases or may reveal novel examples of semidominant inheritance.

- Abstract
Pediatric hand fractures are common and approximately 10% require surgery., Methods: This retrospective cohort study reports on hand fractures in a large pediatric population and identifies the characteristics and patterns of fractures that required surgical correction. A χ
2 analysis was done to evaluate the association between individual fracture variables and surgery. The STROBE checklist was applied., Results: One thousand one-hundred seventy-three hand fractures were reviewed. Peak age was 16 years for boys and 14 years for girls. Most fractures were closed (96.0%) and nonrotated (91.3%), and had no concomitant soft tissue injury (72.7%). More than half (56.3%) were nonepiphyseal plate fractures; yet as a single diagnosis, Salter-Harris II fractures were most common (30.2%). The following variables were significantly associated with surgery: open fractures, rotational deformity, distal phalangeal fracture location, multiple fractures, oblique pattern, comminution, displacement >2 mm, intra-articular involvement, and angulation >15°. Most fractures required only immobilization and early range of motion (64.3%). Closed reduction was required in 22.7%. Minor surgery by the primary provider was performed in 3.2% of fractures. Surgery by a hand surgeon was performed in 9.8%. The most common patterns requiring surgery were proximal or middle phalanx head or neck fractures (38.2%) and metacarpal midshaft fractures (20.9%). The most common operation was open reduction internal fixation (52.2%)., Conclusions: Pediatric hand fractures are common, but 90.2% do not require surgery and, as such, primary providers play a key role in management. Certain fracture variables and patterns are more likely to lead to surgery., Competing Interests: Disclosure: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2020 The Authors.

Hartley RL, Todd AR, Harrop AR, and Fraulin FOG
- Abstract
Background: Pediatric hand fractures are common, but few require surgery; therefore, these fractures are often perceived to be overreferred. Our objective is to systematically identify and describe pediatric hand fracture referring practices., Method: A scoping review was performed, searching electronic databases and grey literature up to January 2018 to identify referring practices for children (17 years and younger) with hand fractures (defined as radiographically confirmed fractures distal to the carpus) to hand surgeons. All study designs were included, and study selection and data extraction were independently performed in duplicate by 2 reviewers. Outcomes included referring rates, necessity of referral, referring criteria, and management of fractures., Results: Twenty (10 cross-sectional, 7 prospective cohorts, and 3 narrative reviews) studies reporting on referring practices or management of 21,624 pediatric hand fractures were included. Proportion of pediatric hand fractures referred to hand surgeons ranged from 6.5% to 100%. Unnecessary referral, defined as those fractures within the scope of primary care management, ranged from 27% to 78.1%. Ten studies reported referring criteria, with 14 unique criteria identified. The most common referring criteria were displacement (36.4%), loss of joint congruity (36.4%), and instability (36.4%). The most common justification for these criteria was increased likelihood of requiring surgery. The most common initial management was immobilization (66%-100%). Final management was provided by orthopedic or plastic hand surgeons with 0% to 32.9% of fractures requiring surgery., Conclusion: Referring practices vary widely in the literature. Major gaps in the literature include objective measures and justification for referring criteria and primary care education on hand fracture referring practices., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© 2019 The Author(s).)

Steve AK, Schrag CH, Kuo A, and Harrop AR
- Abstract
The objective of this study was to compare the costs of performing metacarpal fracture fixation in minor surgery (MS) versus the main operating room (OR) at a tertiary care center in Calgary, Alberta, from the institutional perspective., Methods: Data were extracted from the Operating Room Information System and the Business Advisory System by a financial analyst. All data were based on actual expenses from the 2016-2017 fiscal year (US$). Direct costs included: staffing, supply, day (outpatient) surgery unit, post-anesthesia care unit (PACU), and anesthesia (anesthesiologist and equipment) costs. Surgeon and hardware costs were deemed neutral and excluded from the analysis., Results: The total cost of metacarpal fixation in MS was $250, compared to $2,226 in the OR, after surgeon and hardware costs were excluded. Staffing costs are a major contributing factor to cost by location ($75 in MS versus $233 in OR), largely attributable to 0.5 nursing staff per room in MS compared to 3 nursing staff per room in the OR. Supply costs (minor tray, $94 versus case cart, $247) are also greater for OR cases. The combined costs for DSU ($465), PACU ($435), and anesthesia ($247) totaled $1,147 and are only incurred for OR cases., Conclusions: Repair of metacarpal fractures in MS represents a substantial cost-minimization strategy from the institutional perspective. Staffing and supply costs by location and the additional combined costs of DS, PACU, and anesthesia are all contributing factors., (Copyright © 2019 The Authors.

Cawthorn TR, Fraulin FOG, and Harrop AR
- Abstract
Background: Infantile lip hemangiomas are challenging to manage due to the functional and aesthetic importance of the lips. Hemangiomas in this region may lead to significant complications including ulceration, feeding difficulties, and lip contour distortion requiring surgical intervention., Methods: A retrospective chart review of children with focal lip hemangiomas treated at our institution between January 2000 and December 2016 was conducted. Patient demographics, lesion characteristics, complications, treatments, and outcomes were collected. Lesions were classified based on depth (superficial, deep, or mixed depth), vermillion border involvement, and location., Results: One hundred and two patients with focal lip hemangiomas were identified; 45.1% were managed expectantly, 43.1% were treated medically, and 18.6% required surgery. Residual lip contour deformity following involution was the most common complication (26.5% of patients). Ulceration during the proliferation phase was reported in 14.7% of patients, leading to significant feeding difficulties in 9.8% of patients. All ulcerations occurred in lesions with a superficial component. None of the patients with superficial lesions underwent surgery; 27.1% of patients with deep or mixed depth hemangiomas required surgical treatment to restore lip contour., Conclusions: Lip hemangiomas have high rates of complications that seem to be related to lesion morphology and phase of growth. Ulceration occurs during the early proliferative phase and is most frequently associated with mixed depth hemangiomas. Residual lip contour deformities are identified in the involution phase; presence of a deep component is the primary factor in predicting the need for surgical intervention in these patients., (Copyright © 2019 The Authors.

- Abstract
Objective: Perforator flaps are one possible surgical treatment for burn scar contractures; however, a review of evidence on this topic is lacking., Methods: MEDLINE was searched for articles related to perforator flaps for burn contractures. Following title and abstract screen, full texts were searched to identify articles describing perforator flaps for burn scar joint contractures. Data were extracted and summarized descriptively. Only articles that contained ≥10 patients with burn scar contracture were considered., Results: Two hundred forty-eight articles were identified, of which 17 met criteria for review. Of these, 16 were low-quality case series, while 1 was an open randomized controlled trial. In total, perforator flaps were performed on 339 patients (age range: 3-75 years), with the most common contracture locations being cervical (n = 218) and knee (n = 41). Nine of the 17 articles described a rehabilitation strategy. In general, functional outcomes were excellent, with the majority of patients experiencing return of normal joint range of motion and no recontracture. Compared to full-thickness skin grafts, perforator flaps showed greater improvements in joint range of motion. Cosmetically, perforator flaps were shown to have good color match with surrounding tissue, good contour around anatomical landmarks, and improved overall patient appearance. The most common complications were marginal flap necrosis (n = 26 patients) and venous congestion (n = 17 patients)., Conclusions: Preliminary evidence from low-quality case series and 1 high-quality trial suggests perforator flaps may be successful for resurfacing released burn scar contractures; however, there is a need for additional trials comparing perforator flaps to other approaches., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Purpose: The purpose of this study was to examine the perceived satisfaction and barriers to care for transgender patients after they decide to undergo gender-affirming surgery (GAS)., Method: A survey consisting of 21 multiple-choice and short-answer questions was distributed to transgender organizations and online forums across Canada and the United States. The data were then analyzed using descriptive statistics., Results: There were 32 participants, 12 who identified as female to male and 20 as male to female. The mean age was 36 years, with a range of 18 to 81 years. The mean age of their first GAS was 33 years, and the range of wait time was 6 months to 7 years. Most of the participants received information about GAS from transgender websites and transgender surgery clinics (91% and 50%, respectively). Most participants (74%) felt like they had access to appropriate care and 89% felt like their surgeons provided enough information about GAS. There were 38% of participants who would change their experience with GAS. Participants stated several barriers toward receiving GAS: financial (73%), finding a physician (65%), and access to information (63%). Surgical transition was important to the quality of life for 91% of participants and 100% were happy with their decision to undergo GAS., Conclusions: Transgender participants demonstrated that GAS is important to their quality of life and this study showed significant barriers to GAS., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Upper trunk obstetric brachial plexus injury can cause profound shoulder and elbow dysfunction. Although neuroma excision with interpositional sural nerve grafting is the current gold standard, distal nerve transfers have a number of potential advantages. The goal of this study was to compare the clinical outcomes and health care costs between nerve grafting and distal nerve transfers in children with upper trunk obstetric brachial plexus injury., Methods: In this prospective cohort study, children who underwent triple nerve transfers were followed with the Active Movement Scale for 2 years. Their outcomes were compared to those of children who underwent nerve graft reconstruction. To assess health care use, a cost analysis was also performed., Results: Twelve patients who underwent nerve grafting were compared to 14 patients who underwent triple nerve transfers. Both groups had similar baseline characteristics and showed improved shoulder and elbow function following surgery. However, the nerve transfer group displayed significantly greater improvement in shoulder external rotation and forearm supination 2 years after surgery (p < 0.05). The operative time and length of hospital stay were significantly lower (p < 0.05), and the overall cost was approximately 50 percent less in the nerve transfer group., Conclusion: Triple nerve transfer for upper trunk obstetric brachial plexus injury is a feasible option, with better functional shoulder external rotation and forearm supination, faster recovery, and lower cost compared with traditional nerve graft reconstruction., Clinical Question/level of Evidence: Therapeutic, II.

- Abstract
Background: Sternal wound infection (SWI) in patients undergoing coronary artery bypass grafting (CABG) can carry a significant risk of morbidity and mortality. The objective of this work is to describe the methods used to identify cases of SWI in an administrative database and to demonstrate the effectiveness of using an International Classification of Diseases, Tenth Revision (ICD-10) coding algorithm for this purpose., Methods: ICD-10 codes were used to identify cases of SWI within one year of CABG between April 2002 and November 2009. We randomly chose 200 charts for detailed chart review (100 from each of the groups coded as having SWI and not having SWI) to determine the utility of the ICD-10 coding algorithm., Results: There were 2,820 patients undergoing CABG. Of these, 264 (9.4 percent) were coded as having SWI. Thirty-eight cases of SWI were identified by chart review. The ICD-10 coding algorithm of T81.3 or T81.4 was able to identify incident SWI with a positive predictive value of 35 percent and a negative predictive value of 97 percent. The agreement between the ICD-10 coding algorithm and presence of SWI remained fair, with an overall kappa coefficient of 0.32 (95 percent confidence interval, 0.22-0.43). The effectiveness of identifying deep SWI cases is also presented., Conclusions: This article describes an effective algorithm for identifying a cohort of patients with SWI following open sternotomy in large databases using ICD-10 coding. In addition, alternative search strategies are presented to suit researchers' needs.

- Abstract
Background: It appears that the medical profile of patients undergoing coronary artery bypass graft (CABG) surgery has changed. The impact of this demographic shift on CABG outcomes, such as sternal wound dehiscence, is unclear., Objectives: To quantify the incidence and trends of sternal wound dehiscence, quantify the demographic shift of those undergoing CABG and identify patient factors predictive of disease., Methods: A prospective analysis was performed on a historical cohort of consecutive patients who underwent CABG (without valve replacement) in Alberta between April 1, 2002 and November 30, 2009. The incidence and trends of sternal wound dehiscence were determined. In addition, the trend of the mean Charlson index score and European System for Cardiac Operative Risk Evaluation (EuroSCORE) (capturing patient comorbidities) was analyzed. Univariable analysis and multivariable models were performed to determine factors predictive of wound dehiscence., Results: A total of 5815 patients underwent CABG during the study period. The incidence proportion of sternal wound dehiscence in Alberta was 1.86% and the incidence rate was 1.98 cases per 100 person-years. Although both the EuroSCORE and Charlson scores significantly increased over the study period, the incidence of sternal wound dehiscence did not change significantly. Factors predictive of sternal wound dehiscence were diabetes (OR 2.97 [95% CI 1.73 to 5.10]), obesity (OR 1.55 [95% CI 1.05 to 2.27]) and female sex (OR 1.90 [95% CI 1.26 to 2.87])., Conclusions: The incidence proportion of sternal wound dehiscence in Alberta was comparable with the incidence previously published in the literature. While patients undergoing CABG had worsening medical profiles, the incidence of sternal wound dehiscence did not appear to be increasing significantly.

- Abstract
Background: Pulmonary complications are common after major head and neck oncologic surgery with microsurgical reconstruction and are associated with increased mortality and morbidity. Clinical care pathways are evidence-based tools that reduce unnecessary practice variation and ultimately improve patient outcomes. In this study, the authors evaluate the effectiveness of a comprehensive care pathway on reducing postoperative pulmonary complications and hospital length of stay in patients undergoing major head and neck carcinoma resection with free flap reconstruction., Methods: Fifty-five consecutive patients treated according to a prescribed postoperative clinical care pathway were compared to a historical cohort of patients treated before the implementation of the pathway. The incidence of pulmonary complications, hospital length of stay, and free flap survival were compared between the control and intervention groups., Results: Patients on the clinical care pathway had 32.5 percent fewer pulmonary complications (p < 0.0001) and 7.4 days' shorter hospital length of stay (p = 0.0007) than patients not on the postoperative pathway. There was no significant difference in the rate of flap reoperation., Conclusions: A multidisciplinary, comprehensive, clinical care pathway for patients undergoing major head and neck surgery with microsurgical reconstruction is effective in reducing postoperative pulmonary complications and hospital length of stay. The postoperative pathway is safe in this patient population and should be considered for adoption into clinical practice., Clinical Question/level of Evidence: Therapeutic, III.

- Abstract
Objective: To examine treatment indications, efficacy and side effects of oral beta-blockers for the treatment of problematic hemangiomas., Methods: A retrospective review of patients with hemangiomas presenting to the Alberta Children's Hospital Vascular Birthmark Clinic (Calgary, Alberta) between 2009 and 2011 was conducted. The subset of patients treated with oral beta-blockers was further characterized, investigating indication for treatment, response to treatment, time to resolution of indication, duration of treatment, occurrence of rebound growth and side effects of therapy., Results: Between 2009 and 2011, 311 new patients with hemangiomas were seen, of whom 105 were treated with oral beta-blockers. Forty-five patients completed beta-blocker treatment while the remainder continue to receive therapy. Indications for treatment were either functional concerns (68.6%) or disfigurement (31.4%). Functional concerns included ulceration (29.5%), periocular location with potential for visual interference (28.6%), airway interference (4.8%), PHACES syndrome (3.8%), auditory interference (0.95%) and visceral location with congestive heart failure (0.95%). The median age at beta-blocker initiation was 3.3 months; median duration of therapy was 10.6 months; and median maximal treatment dose was 1.5 mg/kg/day for propranolol and 1.6 mg/kg/day for atenolol. Ninety-nine patients (94.3%) responded to therapy with size reduction, colour changes, softened texture and/or healing of ulceration. Rebound growth requiring an additional course of therapy was observed in 23 patients. Side effects from beta-blockers included cool extremities (26.7%), irritability (17.1%), lower gastrointestinal upset (14.3%), emesis (11.4%), hypotension (10.5%), poor feeding (7.6%), lethargy (4.8%), bronchospasm (0.95%) and rash (0.95%). Side effects did not result in complete discontinuation of beta-blocker treatment in any case; however, they prompted a switch to a different beta-blocker preparation in some cases. Resolution of the primary indication, requiring a median time of three months, occurred in 87 individuals (82.9%)., Conclusions: Treatment of infantile hemangiomas with oral beta-blocker therapy is highly effective and well tolerated, with more than 94% of patients demonstrating a response to treatment and 90% showing resolution of the primary functional indication for treatment.

- Abstract
Rotationplasty is a reconstructive, limb-sparing option for management of lower extremity bone deficiency. This technique involves an intercalary resection, followed by 180° rotation of the distal limb to allow the ankle to function as a knee joint when it is fitted with a modified below-knee prosthesis. Gait analysis and functional outcome studies have reported favorable results with rotationplasty compared with those of above-knee amputation. Moreover, patient satisfaction with rotationplasty is higher than with other limb salvage procedures. The primary drawback of this procedure is patient acceptance of the limb's appearance.

- Abstract
Background: Prolonged procedure time in head and neck cancer ablation and free flap reconstruction cases has been shown to significantly increase perioperative complications. The authors' objective was to evaluate the effectiveness of a standardized surgical nursing team for head and neck cancer ablation and free flap reconstruction operations for reducing procedure time., Methods: A retrospective cohort analysis of consecutive patients presenting for head and neck cancer ablation and free flap reconstruction between January 1, 2007, and September 1, 2010, was performed. A standardized head and neck surgical nursing team was introduced on May 1, 2009, at our center. Procedure time and case time were measured before and after the introduction of the team. Univariable analyses were performed to evaluate the difference in procedure and case time between the two cohorts. A multivariable linear regression model was developed to control for confounding variables., Results: There were 52 cases before the team was introduced and 49 cases after. Mean procedure time was reduced by 47.1 minutes (p = 0.04) and mean case time was reduced by 68.9 minutes (p = 0.01) after team introduction. The multivariable linear regression analysis demonstrated a significant reduction in operative time after team introduction, controlling for confounding variables., Conclusions: The introduction of a standardized surgical nursing team led to a significant reduction in procedure and case time. A standardized team approach improves operating room efficiency in complex cases such as free flap reconstruction following tumor ablation., Clinical Question/level of Evidence: Therapeutic, III.

- Abstract
Introduction: Databases are useful tools in clinical settings. The authors review the benefits and challenges associated with the development and implementation of an efficient electronic database for the multidisciplinary Vascular Birthmark Clinic at the Alberta Children's Hospital, Calgary, Alberta., Methods: The content and structure of the database were designed using the technical expertise of a data analyst from the Calgary Health Region. Relevant clinical and demographic data fields were included with the goal of documenting ongoing care of individual patients, and facilitating future epidemiological studies of this patient population. After completion of this database, 10 challenges encountered during development were retrospectively identified. Practical solutions for these challenges are presented., Results: THE CHALLENGES IDENTIFIED DURING THE DATABASE DEVELOPMENT PROCESS INCLUDED: identification of relevant data fields; balancing simplicity and user-friendliness with complexity and comprehensive data storage; database expertise versus clinical expertise; software platform selection; linkage of data from the previous spreadsheet to a new data management system; ethics approval for the development of the database and its utilization for research studies; ensuring privacy and limited access to the database; integration of digital photographs into the database; adoption of the database by support staff in the clinic; and maintaining up-to-date entries in the database., Conclusions: There are several challenges involved in the development of a useful and efficient clinical database. Awareness of these potential obstacles, in advance, may simplify the development of clinical databases by others in various surgical settings.

- Abstract
Our aim was to find out if a modified intravenous regional anaesthetic block technique, used for invasive surgical procedures on the distal forearm and hand, results in a drier operative field than traditional methods. Twenty consenting adult (age > 18) patients who were to have an operation on the distal forearm or hand were randomised into two groups (n=10 in each). The first group was using a traditional bier block, with a double upper arm tourniquet. The second group was using a modified regional anaesthetic block technique, with a single upper arm tourniquet, and a single forearm tourniquet. All operative fields were recorded photographically and judged by the operating surgeon as "wet" or "dry". Analgesic requirements and subjective pain were recorded. Plasma lignocaine concentrations were measured. "Wet" operative fields were seen in 6 of the conventional and 0 of the modified group (p=0.01). Patients in the modified group were more comfortable during the procedures (p=0.004). This benefit was not sustained postoperatively (p=0.57). Plasma lignocaine concentrations were higher in the conventional group (p=0.004). The modified technique was as safe as the conventional technique but has the benefits of a drier surgical field and improved intraoperative comfort for patients.

- Abstract
Background: The rate of breast reconstruction following mastectomy is increasing, and currently sits at about 15%. Free flap reconstruction techniques using the thoracodorsal vessels as recipients provide an opportunity for a "second look" at the axillary nodal basin post-mastectomy. The purpose of this study was to determine the occult malignancy rate associated with free flap breast reconstruction., Methods: A retrospective chart review was performed to ascertain the occult malignancy rate of women who received a delayed free flap reconstruction at our institution between 1990 and 2001. Any additional therapy as a result of a positive result was also recorded., Results: Free flap breast reconstructions between 1990 and 2001 totalled 322, and of those 136 reconstructions were delayed and met our inclusion criteria. An occult malignancy rate of 3.6% (five patients) was identified for these patients. Four patients received additional therapy as a result of this finding., Conclusion: This study serves to alert reconstructive surgeons to the potential for finding occult tumour during free flap breast reconstruction.

- Abstract
Background: Evidence-based medicine, particularly randomized controlled trials, influences many daily decisions within the medical specialties. The structure of questions asked during the history and selection of physical examination maneuvers, diagnostic tests, and treatment regimens are all guided by evidence-based medicine. Implementation of evidence-based medicine has been slower in surgical practice. The purpose of this study was to survey published plastic surgery literature to evaluate changes in the level of evidence from pre-evidence-based medicine popularization to the present time., Methods: Articles from Plastic and Reconstructive Surgery for the years 1983, 1993, and 2003 were ranked by a five-point level of evidence scale. The highest level of evidence value (1) was given to randomized clinical trials and the lowest value (5) was given to individual case reports; 989 articles were ranked., Results: The average level of evidence of an article published in 1983 was lower than that of one published in 2003 (4.42 versus 4.16, respectively), and the majority of research (86.9 percent in 2003) remained largely uncontrolled and descriptive in nature. However, there was a trend toward higher-quality research. The percentage of studies with control or placebo groups nearly doubled from 1983 to 2003 (from 7.21 percent to 13.7 percent), and the number of randomized clinical trials increased (zero versus seven)., Conclusion: The plastic surgery literature has responded to the demand for more evidence-based medicine, but the rate of change has been slow and the field will likely never enjoy the high level of evidence of medical fields.

- Abstract
Objectives: To examine injury mortality rates in Native and non-Native children in the province of Alberta, Canada, over a 10-year period, temporal trends in injury mortality rates (Native vs. non-Native), as well as relative risks of injury mortality (Native vs. non-Native) by injury mechanism and intent, were calculated., Methods: An observational, population-based study design was used. Mortality data were obtained from provincial vital statistics, with injury deaths identified using external injury codes (E-codes). The relative risk (RR) of injury mortality (Native vs. non-Native) along with 95% confidence intervals (CIs) were calculated. Stratified analyses and Poisson regression modeling were used to calculate adjusted relative risk., Results: Injury mortality rates declined over the study period, with no difference in the rate of decline between Native and non-Native children. The adjusted relative risk for all-cause injury death (Native vs. non-Native) was 4.6 (95% CI 4.1 to 5.2). The adjusted relative risks (Native vs. non-Native) by injury intent categories were: unintentional injuries, 4.0 (95% CI 3.5 to 4.6); suicide, 6.6 (95% CI 5.2 to 8.5); and homicide, 5.1 (95% CI 3.0 to 8.5). Injury mortality rates were consistently higher for Native children across all injury mechanism categories. The largest relative risks (Native vs. non-Native) were pedestrian injury (RR = 17.0), accidental poisoning (RR = 15.4), homicide by piercing objects (RR = 15.4), and suicide by hanging (RR = 13.5)., Conclusion: The burden of injury mortality is significantly greater in Native children compared with non-Native children. Therefore, injury prevention strategies that target both intentional and unintentional injuries are needed.

- Abstract
Background: Anecdotal experience has suggested that there is a higher frequency of maxillofacial injuries among motor vehicle collisions involving moose., Objectives: A retrospective cohort study design was used to investigate the incidence of various injuries resulting from moose-motor vehicle collisions versus other high-speed motor vehicle collisions., Methods: A chart review was conducted among patients presenting to a Canadian regional trauma centre during the five-year period from 1996 to 2000., Results: Fifty-seven moose-motor vehicle collisions were identified; 121 high-speed collisions were randomly selected as a control group. Demographic, collision and injury data were collected from these charts and statistically analyzed. The general demographic features of the two groups were similar. Moose collisions were typically frontal impact resulting in windshield damage. The overall injury severity was similar in both groups. Likewise, the frequency of intracranial, spinal, thoracic and extremity injuries was similar for both groups. The group involved in collisions with moose, however, was 1.8 times more likely then controls to sustain a maxillofacial injury (P=0.004) and four times more likely to sustain a maxillofacial fracture (P=0.006)., Conclusions: Occupants of motor vehicles colliding with moose are more likely to sustain maxillofacial injuries than those involved in other types of motor vehicle collisions. It is speculated that this distribution of injuries relates to the mechanism of collision with these large mammals with a high centre of gravity.

Background: Aboriginal Canadians are considered to be at increased risk of major trauma. However, population-based studies characterizing the distribution, determinants and outcomes of major trauma in this group are lacking. We sought to measure the impact of ethnicity, as reflected by Aboriginal status, on the incidence of severe trauma and to broadly define the epidemiologic characteristics of severe trauma among status Aboriginal Canadians in a large health region., Methods: This population-based, observational study involves all adults (people > or = 16 years) resident in the Calgary Health Region between Apr. 1, 1999, and Mar. 31, 2002. Stratification of the population into status Aboriginal Canadians and the reference population was performed by Alberta Health and Wellness using an alternate premium arrangement field within the personal health care number. Injury incidence was determined by identifying all injuries with severity scores of 12 or greater in the Alberta Trauma Registry, regional corporate data and the Office of the Medical Examiner., Results: Aboriginal Canadians were at much higher risk than the reference population in the Calgary Health Region of sustaining severe trauma (257.2 v. 68.8 per 100,000; relative risk [RR] 3.7, 95% confidence interval [CI] 3.0-4.6). Aboriginal Canadians were found to be at significantly increased risk of injuries resulting from motor vehicle crashes (RR 4.8, 95% CI 3.5-6.5), assault (RR 11.1, 95% CI 6.2-18.6) and traumatic suicide (RR 3.1, 95% CI 1.4-6.1). A trend toward higher median injury severity scores was observed among Aboriginal Canadians (21 v. 18, p = 0.09). Although the case-fatality rate among Aboriginal Canadians was less than half that in the reference population (14/93 [15%] v. 531/1686 [31%], p < 0.0001), population mortality was almost 2 times greater (RR = 1.8, 95% CI 1.0-3.0, p = 0.046)., Interpretation: Severe trauma disproportionately affects Aboriginal Canadians.

- Abstract
A new method of delivery of epithelial suspensions with use of an aerosolization apparatus was examined in the pig. Full-thickness pig skin was harvested, and an epithelial suspension was created using standard techniques of dispase and trypsin. Twenty-four hours after skin harvest, four full-thickness wounds were created on the flanks of the pig. The control wound was sprayed with a solution without epithelial cells. The three experimental wounds were sprayed with epithelial cell suspensions (integral 10(6) cells/suspension). Weekly evaluation with photographs, biopsies, and tracings were done for 4 weeks. At 10 weeks, the entire process was repeated with new wounds on the pig's back. Thirty-five wounds in five pigs were evaluated: 10 control (5 flank, 5 back) and 25 experimental (15 flank, 10 back). Control wounds healed by contraction alone, with epithelium at the edges only. After 4 weeks, an open area remained. Central epithelial islands developed in experimental wounds at 2 weeks. These islands coalesced to close the wounds by 4 weeks. Histology at 1 week showed groups of epithelial cells deeply embedded in granulation tissue. These groups became immature epithelial layers on the surface by 2 weeks, and all layers of epithelium were present by 4 weeks. Overall, flank experimental wounds epithelialized sooner, but contracted at the same rate as control wounds. In conclusion, epithelial cells can be delivered by an aerosolization apparatus and remain viable and proliferative in a pig model.

- Abstract
Development of hypertrophic scarring (HTS) is a major problem for patients who survive extensive thermal injuries. HTS and other fibroproliferative disorders are associated with excessive accumulation of collagen and other extracellular matrix proteins. Recent in vitro and in vivo studies have demonstrated that proteins of the interferon family have an inhibitory effect on collagen production by fibroblasts in some fibroproliferative disorders. This study investigated the effects of interferon-gamma (IFN-gamma) on cell proliferation, collagen production, and expression of types I and III procollagen mRNA in human postburn HTS fibroblasts. Paired fibroblast cultures were established from explants of biopsies obtained from HTS and normal skin (matched for location and skin tension) in five patients recovering from thermal injuries. Thus, normal dermis from each patient was used as a paired control. Administration of IFN-gamma (1000 U/ml) to proliferating fibroblast cultures for 5 days resulted in 51% reduction (P < 0.05) in HTS cell proliferation. Using hydroxyproline as an index for collagen production, a 34% reduction (P < 0.05) in collagen synthesis was observed in HTS fibroblast culture media after treatment with IFN-gamma (1000 u/ml) for 48 hr. Northern blot analysis demonstrated 55 and 36% reductions (P < 0.05 for each) in type I and type III procollagen mRNA levels, respectively, after treatment for 12 hr with IFN-gamma (1000 u/ml). The effect of IFN-gamma on each of these parameters was at least as pronounced in HTS fibroblasts as their normal controls.(ABSTRACT TRUNCATED AT 250 WORDS)
