The use of antibiotics in the treatment of pediatric varicella patients: real-world evidence from the multi-country MARVEL study in Latin America & Europe.

BACKGROUND: Varicella is a highly contagious childhood disease. Generally benign, serious complications necessitating antibiotic use may occur. The objective of this study was to characterize the rate, appropriateness and patterns of real-world antibiotic prescribing for management of varicella-associated complications, prior to universal varicella vaccination (UVV) implementation. METHODS: Pooled, post-hoc analysis of 5 international, multicenter, retrospective chart reviews studies (Argentina, Hungary, Mexico, Peru, Poland). Inpatient and outpatient primary pediatric (1-14 years) varicella cases, diagnosed between 2009 and 2016, were eligible. Outcomes, assessed descriptively, included varicella-associated complications and antibiotic use. Three antibiotic prescribing scenarios were defined based on complication profile in chart: evidence of microbiologically confirmed bacterial infection (Scenario A); insufficient evidence confirming microbiological confirmation (Scenario B); no evidence of microbiological confirmation (Scenario C). Stratification was performed by patient status (inpatient vs. outpatient) and country. RESULTS: Four hundred one outpatients and 386 inpatients were included. Mean (SD) outpatient age was 3.6 (2.8) years; inpatient age was 3.1 (2.8) years. Male gender was predominant. Overall, 12.2% outpatients reported ≥1 infectious complication, 3.7% ≥1 bacterial infection, and 0.5% ≥1 microbiologically confirmed infection; inpatient complication rates were 78.8, 33.2 and 16.6%, respectively. Antibiotics were prescribed to 12.7% of outpatients and 68.9% of inpatients. Among users, ß-lactamases (class), and clindamycin (agent), dominated prescriptions. Scenario A was assigned to 3.9% (outpatients) vs 13.2% (inpatients); Scenario B: 2.0% vs. 6.0%; Scenario C: 94.1% vs. 80.8%. CONCLUSIONS: High rates of infectious complications and antibiotic use are reported, with low rates of microbiological confirmation suggesting possible antibiotic misuse for management of varicella complications.

Behavioral Economics and Physician Board Meetings: Opportunity Cost, Regret, and Their Mitigation in Orthopaedic Surgery.

Health care is a business. Health care providers must become familiar with terms such as opportunity costs, the potential loss or gain when one choice is made in lieu of another. The purpose of this study was to calculate the opportunity cost of two orthopaedic surgery society board meetings and discuss these in the context of behavioral economics and regret. A literature search was conducted to determine an orthopaedic surgeon's average yearly salary, hours worked per week, and weeks worked per year. The details of two orthopaedic surgery professional society meetings that one senior author (CSR) attended were used to calculate opportunity cost. Although the true benefits are multifactorial and difficult to objectively quantify, awareness of the cost-benefit ratio can help guide time and resource management to maximize the return on investment while minimizing buyer's remorse and perhaps influence the media by which medical meetings are held in the future.

Initial Medication Adherence-Review and Recommendations for Good Practices in Outcomes Research: An ISPOR Medication Adherence and Persistence Special Interest Group Report.

BACKGROUND: Positive associations between medication adherence and beneficial outcomes primarily come from studying filling/consumption behaviors after therapy initiation. Few studies have focused on what happens before initiation, the point from prescribing to dispensing of an initial prescription. OBJECTIVE: Our objective was to provide guidance and encourage high-quality research on the relationship between beneficial outcomes and initial medication adherence (IMA), the rate initially prescribed medication is dispensed. METHODS: Using generic adherence terms, an international research panel identified IMA publications from 1966 to 2014. Their data sources were classified as to whether the primary source reflected the perspective of a prescriber, patient, or pharmacist or a combined perspective. Terminology and methodological differences were documented among core (essential elements of presented and unpresented prescribing events and claimed and unclaimed dispensing events regardless of setting), supplemental (refined for accuracy), and contextual (setting-specific) design parameters. Recommendations were made to encourage and guide future research. RESULTS: The 45 IMA studies identified used multiple terms for IMA and operationalized measurements differently. Primary data sources reflecting a prescriber's and pharmacist's perspective potentially misclassified core parameters more often with shorter/nonexistent pre- and postperiods (1-14 days) than did a combined perspective. Only a few studies addressed supplemental issues, and minimal contextual information was provided. CONCLUSIONS: General recommendations are to use IMA as the standard nomenclature, rigorously identify all data sources, and delineate all design parameters. Specific methodological recommendations include providing convincing evidence that initial prescribing and dispensing events are identified, supplemental parameters incorporating perspective and substitution biases are addressed, and contextual parameters are included.

The health and economic impact of vaccination with 7-valent pneumococcal vaccine (PCV7) during an annual influenza epidemic and influenza pandemic in China.

BACKGROUND: China has experienced several severe outbreaks of influenza over the past century: 1918, 1957, 1968, and 2009. Influenza itself can be deadly; however, the increase in mortality during an influenza outbreak is also attributable to secondary bacterial infections, specifically pneumococcal disease. Given the history of pandemic outbreaks and the associated morbidity and mortality, we investigated the cost-effectiveness of a PCV7 vaccination program in China from the context of typical and pandemic influenza seasons. METHODS: A decision-analytic model was employed to evaluate the impact of a 7-valent pneumococcal vaccine (PCV7) infant vaccination program on the incidence, mortality, and cost associated with pneumococcal disease during a typical influenza season (15% flu incidence) and influenza pandemic (30% flu incidence) in China. The model incorporated Chinese data where available and included both direct and indirect (herd) effects on the unvaccinated population, assuming a point in time following the initial introduction of the vaccine where the impact of the indirect effects has reached a steady state, approximately seven years following the implementation of the vaccine program. Pneumococcal disease incidence, mortality, and costs were evaluated over a one year time horizon. Healthcare costs were calculated using a payer perspective and included vaccination program costs and direct medical expenditures from pneumococcal disease. RESULTS: The model predicted that routine PCV7 vaccination of infants in China would prevent 5,053,453 cases of pneumococcal disease and 76,714 deaths in a single year during a normal influenza season.The estimated incremental-cost-effectiveness ratios were ¥12,281 (US$1,900) per life-year saved and ¥13,737 (US$2,125) per quality-adjusted-life-year gained. During an influenza pandemic, the model estimated that routine vaccination with PCV7 would prevent 8,469,506 cases of pneumococcal disease and 707,526 deaths, and would be cost-saving. CONCLUSIONS: Routine vaccination with PCV7 in China would be a cost-effective strategy at limiting the negative impact of influenza during a typical influenza season. During an influenza pandemic, the benefit of PCV7 in preventing excess pneumococcal morbidity and mortality renders a PCV7 vaccination program cost-saving.

A systematic literature review of psychosocial and behavioral factors associated with initial medication adherence: a report of the ISPOR medication adherence & persistence special interest group.

OBJECTIVES: Numerous factors influencing medication adherence in chronically ill patients are well documented, but the paucity of studies concerning initial treatment course experiences represents a significant knowledge gap. As interventions targeting this crucial first phase can affect long-term adherence and outcomes, an international panel conducted a systematic literature review targeting behavioral or psychosocial risk factors. METHODS: Eligible published articles presenting primary data from 1966 to 2011 were abstracted by independent reviewers through a validated quality instrument, documenting terminology, methodological approaches, and factors associated with initial adherence problems. RESULTS: We identified 865 potentially relevant publications; on full review, 24 met eligibility criteria. The mean Nichol quality score was 47.2 (range 19-74), with excellent reviewer concordance (0.966, P < 0.01). The most prevalent pharmacotherapy terminology was initial, primary, or first-fill adherence. Articles described the following factors commonly associated with initial nonadherence: patient characteristics (n = 16), medication class (n = 12), physical comorbidities (n = 12), pharmacy co-payments or medication costs (n = 12), health beliefs and provider communication (n = 5), and other issues. Few studies reported health system factors, such as pharmacy information, prescribing provider licensure, or nonpatient dynamics. CONCLUSIONS: Several methodological challenges synthesizing the findings were observed. Despite implications for continued medication adherence and clinical outcomes, relatively few articles directly examined issues associated with initial adherence. Notwithstanding this lack of information, many observed factors associated with nonadherence are amenable to potential interventions, establishing a solid foundation for appropriate ongoing behaviors. Besides clarifying definitions and methodology, future research should continue investigating initial prescriptions, treatment barriers, and organizational efforts to promote better long-term adherence.

Orthopedic surgery postgraduate year 1 intern curriculum improves initial orthopedic in-training examination performance.

OBJECTIVE: To determine the efficacy of an educational curriculum designed for orthopedic surgery postgraduate year 1 (PGY-1) interns to improve initial Orthopedic In-Training Examination (OITE) performance. METHODS: A retrospective cohort study was performed that evaluated the PGY-1 intern OITE performance of one residency training program (n = 55) during 7-year periods before (1996-2002) and after structured curriculum implementation (2003-2009). RESULTS: Linear regression analysis revealed insignificant changes in median PGY-1 intern OITE percentile rank during the precurriculum period (R = 0.08, P = 0.53). Postcurriculum period comparisons revealed significantly improving PGY-1 intern OITE percentile rank (R = 0.46, P = 0.048). Pre- and postcurriculum median US Medical Licensing Examination (USMLE) Step I scores did not display statistically significant differences (218.2 ± 6.6 vs 229.1 ± 13.8, Mann-Whitney U test, z = -1.5, P = 0.10). Spearman rho correlations revealed a moderate relation (r = 0.61) between postcurriculum PGY-1 intern OITE percentile rank and USMLE Step I score, but not during the precurriculum period. A moderate relation (r = 0.50) also was observed between postcurriculum USMLE Step I score and average OITE percentile rank during the 5-year residency program, but not during the precurriculum period. CONCLUSIONS: PGY-1 intern OITE percentile rank improved significantly with the addition of a specially designed educational curriculum. The stronger USMLE Step I score and PGY-1 intern OITE percentile rank relation observed during the postcurriculum period suggests that interns who participated in the educational curriculum were better prepared to translate general medical and patient care knowledge into orthopedic surgery knowledge.

Nonunion of fibula: a systematic review.

PURPOSE: The purpose of this systematic review was to analyse the available evidence regarding nonunions of the fibula. We focussed on the incidence, risk factors, evaluation, and treatment modalities for fibular nonunions as evident in the current literature and propose a treatment algorithm. METHODS: This was an Institutional Review Board (IRB) exempt study performed at a level one trauma centre. We systematically reviewed the published evidence on fibular nonunion or delayed union from 1950 to February, 2011. RESULTS: Twelve articles were included in this systematic review. In summary, nonunion of the fibula is becoming increasingly more common in association with intramedullary nailing of concomitant tibial shaft fractures. A treatment algorithm for nonunion of the fibula has been proposed. CONCLUSIONS: The suspicion for nonunion of the fibula should be heightened in lower leg fractures if the patient is symptomatic, and the progression of healing is not as expected. Ideally, prospective, multicentre studies would be performed to provide more rigorous data on the incidence, risk factors, and optimum treatment.

Lumbar paraspinal compartment syndrome.

The purpose of this study was to systematically review the available evidence on lumbar paraspinal compartment syndrome with specific reference to patient demographics, aetiology, types, diagnosis, clinical features, and treatment. This was an Institutional Review Board-exempt study performed at a Level 1 trauma center. A PubMed search was conducted with the title query: lumbar paraspinal compartment syndrome. Eleven articles met our search criteria. Three of the patients with acute paraspinal compartmental syndrome treated with fasciotomy had a full recovery and were able to resume skiing after four months. The aetiology of the onset of lumbar paraspinal compartment syndrome is broadly divided into acute and chronic. Lumbar paraspinal compartment syndrome is one of the causes of back pain with diagnostic clinical features which should be considered in the differential diagnosis of a patient with low back pain. Prospective multicentre trials may provide the surgeon with more insight into the diagnosis and management of lumbar paraspinal compartment syndrome.

Pelvic compartment syndrome: a systematic review.

Bilateral ureteral obstruction due to traumatic pelvic haematoma and increased pressure in the retroperitoneal space constitute an acute pelvic compartment syndrome. We systematically reviewed the available evidence concerning pelvic compartment syndrome using an online search of the MEDLINE databases OVID and PubMed. There were nine cases of pelvic compartment syndrome. A motor vehicle accident was the most frequent cause of pelvic compartment syndrome. Diagnosis was made using clinical and radiological methods in all cases. Treatment was by surgical decompression in 88% of cases. Observed complications were neurological deficits (44%), muscle atrophy (33%), and renal failure (33%). Pelvic compartment syndrome is as serious as the more common compartment syndromes, requiring high vigilance for diagnosis and surgical decompression for treatment.

Impact of Routine Childhood Immunization in Reducing Vaccine-Preventable Diseases in the United States.

BACKGROUND AND OBJECTIVES: Current routine immunizations for children aged ≤10 years in the United States in 2019 cover 14 vaccine-preventable diseases. We characterize the public-health impact of vaccination by providing updated estimates of disease incidence with and without universally recommended pediatric vaccines. METHODS: Prevaccine disease incidence was obtained from published data or calculated using annual case estimates from the prevaccine period and United States population estimates during the same period. Vaccine-era incidence was calculated as the average incidence over the most recent 5 years of available surveillance data or obtained from published estimates (if surveillance data were not available). We adjusted for underreporting and calculated the percent reduction in overall and age-specific incidence for each disease. We multiplied prevaccine and vaccine-era incidence rates by 2019 United States population estimates to calculate annual number of cases averted by vaccination. RESULTS: Routine immunization reduced the incidence of all targeted diseases, leading to reductions in incidence ranging from 17% (influenza) to 100% (diphtheria, Haemophilus influenzae type b, measles, mumps, polio, and rubella). For the 2019 United States population of 328 million people, these reductions equate to >24 million cases of vaccine-preventable disease averted. Vaccine-era disease incidence estimates remained highest for influenza (13 412 per 100 000) and Streptococcus pneumoniae-related acute otitis media (2756 per 100 000). CONCLUSIONS: Routine childhood immunization in the United States continues to yield considerable sustained reductions in incidence across all targeted diseases. Efforts to maintain and improve vaccination coverage are necessary to continue experiencing low incidence levels of vaccine-preventable diseases.

The BROADEN study: The design of an observational study to assess the absolute burden of HPV-related head and neck cancers.

BACKGROUND: Persistent human papillomavirus (HPV) infection is an important risk factor for a subset of head and neck cancers (HNCs). However, estimates of the HPV-attributable fraction of oropharyngeal cancers vary greatly, and the proportion is increasing. Growing evidence indicates smaller proportions of oral cavity and laryngeal cancers are also HPV-attributable, but this requires further investigation. The primary objective of the BROADEN study is to estimate the fraction of HNCs attributable to HPV in selected European and Asian countries by anatomic site. Secondary objectives are to determine HPV genotypes involved and to describe primary tumor and patient characteristics by HPV status. METHODS: BROADEN is a non-interventional, cross-sectional study of patients with HNC in China, France, Germany, Italy, Japan, Portugal, and Spain. The HPV-attributable HNC fraction will be determined within pre-defined time-periods (2008-2009, 2013-2014 [China only], 2018-2019). Approximately 9000 patients from an estimated 90 hospitals with reference HNC diagnostic units and local reference pathology laboratories will participate. Sample size estimates were generated by grouped anatomic site (oropharynx, oral cavity, nasopharynx, hypopharynx, and larynx) and country. HPV testing (HPV-DNA and p16 immunohistochemistry [IHC]) will be performed at a central laboratory on formalin-fixed paraffin-embedded tissue samples. All HPV-DNA-positive samples and HPV-DNA-negative/p16 IHC-positive samples, plus 10% of remaining HPV DNA-negative (control) samples will be tested for HPV mRNA. DISCUSSION: BROADEN is a large global epidemiologic study to estimate current and recent past HPV burden in oropharyngeal and non-oropharyngeal HNCs. BROADEN is expected to provide robust estimates of HPV attributability by anatomic site in participating countries.

Value of the Immunization Program for Children in the 2017 US Birth Cohort.

BACKGROUND AND OBJECTIVES: We evaluated the economic impact of routine childhood immunization in the United States, reflecting updated vaccine recommendations and recent data on epidemiology and coverage rates. METHODS: An economic model followed the 2017 US birth cohort from birth through death; impact was modeled via a decision tree for each of the vaccines recommended for children by the Advisory Committee on Immunization Practices as of 2017 (with annual influenza vaccine considered in scenario analysis). Using information on historic prevaccine and vaccine-era incidence and disease costs, we calculated disease cases, deaths, disease-related healthcare costs, and productivity losses without and with vaccination, as well as vaccination program costs. We estimated cases and deaths averted because of vaccination, life-years and quality-adjusted life-years gained because of vaccination, incremental costs (2019 US dollars), and the overall benefit-cost ratio (BCR) of routine childhood immunization from the societal and healthcare payer perspectives. RESULTS: Over the cohort's lifetime, routine childhood immunization prevented over 17 million cases of disease and 31 000 deaths; 853 000 life years and 892 000 quality-adjusted life-years were gained. Estimated vaccination costs ($8.5 billion) were fully offset by the $63.6 billion disease-related averted costs. Routine childhood immunization was associated with $55.1 billion (BCR of 7.5) and $13.7 billion (BCR of 2.8) in averted costs from a societal and healthcare payer perspective, respectively. CONCLUSIONS: In addition to preventing unnecessary morbidity and mortality, routine childhood immunization is cost-saving. Continued maintenance of high vaccination coverage is necessary to ensure sustained clinical and economic benefits of the vaccination program.

Pregnancy-related pelvic girdle pain: an update.

A large number of scientists from a wide range of medical and surgical disciplines have reported on the existence and characteristics of the clinical syndrome of pelvic girdle pain during or after pregnancy. This syndrome refers to a musculoskeletal type of persistent pain localised at the anterior and/or posterior aspect of the pelvic ring. The pain may radiate across the hip joint and the thigh bones. The symptoms may begin either during the first trimester of pregnancy, at labour or even during the postpartum period. The physiological processes characterising this clinical entity remain obscure. In this review, the definition and epidemiology, as well as a proposed diagnostic algorithm and treatment options, are presented. Ongoing research is desirable to establish clear management strategies that are based on the pathophysiologic mechanisms responsible for the escalation of the syndrome's symptoms to a fraction of the population of pregnant women.

Review of treatment and diagnosis of acute compartment syndrome of the calf: current evidence and best practices.

Compartment syndrome of the calf has received a great deal of attention in the literature. A MEDLINE search was conducted to identify English-language publications pertaining to compartment syndrome of the leg and calf so that principles, recent evidence, and best practices for the diagnosis and treatment of this syndrome could be reviewed. Clinical series that reported outcomes and diagnostic criteria were reviewed and summarized. The currently available evidence is limited to level IV and V studies. Early diagnosis and treatment of compartment syndromes is associated with better results; however, many patients have chronic symptoms after treatment, even when the diagnosis is made promptly and fasciotomy is performed early. Although compartment syndrome of the leg and calf often has been described in the literature, prospective clinical series are lacking, and meaningful outcomes data are scarce. There is a need for further study on functional outcomes of acute compartment syndrome of the calf, with particular attention to diagnosis and treatment.

Diagnosis and treatment of less common compartment syndromes of the upper and lower extremities: current evidence and best practices.

Compartment syndromes of the forearm, gluteal region, thigh, and foot have not been extensively studied. To provide best-practice recommendations, the available evidence from four systematic reviews of English-language reports with two or more patients with compartment syndromes of the forearm, gluteal region, thigh, and foot were reviewed and compared. For each case of compartment syndrome, the cause, method of diagnosis, treatment options, and outcomes were determined. Most compartment syndromes were caused by trauma, with the exception of gluteal compartment syndrome, which usually resulted from prolonged immobilization and postarthroplasty analgesia. The diagnosis was often based on clinical findings, with compartment pressure measurements performed in approximately 50% of the patients. Compartment pressure measurements of the foot were more commonly obtained (in 64% of the patients). Compartment syndrome of the forearm and thigh were treated surgically in 73% and 100% of patients, respectively. Complications occurred with all four compartment syndromes, with nerve deficits and stiffness being the most common problems. Reports on functional outcomes lacked uniformity and did not allow for meaningful comparisons. Management principles for the less common compartment syndromes are the same as those used in treating compartment syndrome of the calf. Gluteal compartment syndrome usually has a nontraumatic etiology and is less likely to be surgically treated, probably because of major systemic complications and late presentation. Complications are common after these four types of compartment syndrome, but outcomes data are lacking.

Compartment syndrome of the forearm: a systematic review.

In this systematic review, we examined the available evidence regarding compartment syndrome of the forearm. Applying our inclusion criteria, we found 12 articles for a total of 84 cases using the MEDLINE (Ovid) database. All were retrospective studies (level IV evidence). In this study, papers were analyzed for causes, diagnosis, treatment, methods of wound closure, functional outcome, and complications. The most common cause of compartment syndrome of the forearm in children was a supracondylar fracture, while in adults the most common cause was a fracture of the distal radius. The diagnostic criterion used was clinical assessment alone in 48%, and in 52%, a combination of measurement of intracompartmental pressure and clinical assessment was used. The intracompartmental pressure was measured using various techniques including a wick catheter, slit catheter, the Whitesides technique, and the Stryker compartment pressure measuring device. Fasciotomy was the preferred method of treatment (73%). In cases reporting wound management, postfasciotomy skin grafting was needed in 61% of the cases, whereas secondary closure was performed in 39% of the cases. Neurological deficit was the most common complication (21%).

Anterolateral and medial locking plate stiffness in distal tibial fracture model.

BACKGROUND: The purpose of this study was to compare the axial and torsional stiffness between anterolateral and medial distal tibial locking plates in a pilon fracture model. MATERIALS AND METHODS: The biomechanical stiffness of anterolateral or medial plated pilon fracture models was evaluated. Six Sawbones Composite Tibiae with a simulated pilon fracture representing varus or valgus comminution (OTA 43-A2.2) were plated with a Synthes 3.5-mm contoured LCP anterolateral or medial locking distal tibia plate. Load as a function of axial displacement and torque as a function of angular displacement were recorded. Each tibia was tested with a fracture wedge in place and removed with a medial and then anterolateral plate. RESULTS: Loading the tibial plateau medial to the central axis, no significant difference in mean stiffness between the anterolateral and medial plates was demonstrated with the fracture wedge in place. A significant difference was demonstrated with the wedge removed. Loading the plateau posterior to the central axis, no significant difference in mean stiffness between plates was demonstrated with the wedge in place or removed. With the wedge in place, there was a significant difference in mean torsional stiffness for clockwise rotation, but not counterclockwise rotation. With the wedge removed, no significant difference appeared in mean stiffness for clockwise and counterclockwise rotation. CONCLUSION: Distal tibia extra-articular fractures stabilized with anterolateral or medial locking plate constructs demonstrated no statistically significant difference in biomechanical stiffness in compression and torsion testing. CLINICAL RELEVANCE: We believe this study indicates the primary concern when treating a pilon fracture may be soft-tissue considerations. Further clinical studies are required before definitive changes can be recommended regarding pilon fracture fixation.

The management of nonunion and delayed union of patella fractures: a systematic review of the literature.

Nonunion and delayed union of patella fractures are rare conditions that are fraught with challenges. There exists limited evidence in the literature to guide the clinician in the management of these complications. Therefore, the purpose of this study was to perform a systematic review of the available evidence on the management of nonunion and delayed union of patella fractures. A total of five publications which met our criteria were identified and formed the basis of this study. The decision making in the treatment of this condition is based on the functional demands of the patient, the factors that led to the development of the nonunion, the potential impact of the biomechanical effects of a total patellectomy, and the presence of an intact extensor mechanism of the knee for a later reconstructive procedure. Patients with low functional demands may be managed with nonoperative methods; however, those who perform heavy physical work or participate in sports usually require open reduction and internal fixation. Tension band wiring is the treatment of choice for patients suitable for a reconstructive procedure. Partial or total patellectomy is also an option for small distal fragments or an inability to satisfactorily perform internal fixation.

Venous thromboembolism in shoulder surgery: a systematic review.

Although it is generally believed that venous thromboembolism (VTE) after shoulder surgery is very rare, there are increasing reports of deep venous thrombosis (DVT) and pulmonary embolism (PE) associated with shoulder surgery. To our knowledge only few studies have reviewed the available evidence on the subject. The purpose of this study was to review the available evidence in the published literature regarding incidence, risk factors, diagnosis and management of DVT/PE following shoulder surgery (Level IV evidence).

The anterolateral incision for pilon fracture surgery: an anatomic study of cutaneous blood supply.

The purpose of this study was to examine the blood supply to the adjacent skin and its vulnerability to anterolateral tibial plating performed with fibular plating through a single surgical incision. Ten lightly embalmed cadaver legs without a history of lower extremity trauma or surgery with a mean age of 71 years (range, 57 to 87 years) were used for this investigation. Each specimen was injected with a commercially available silicone compound through the popliteal artery. The left leg was plated through a modified extensile Böhler approach and the right leg served as the control. Each leg was anatomically dissected. All measurements were taken using a digital caliper by a single investigator. A mean of 93 (range, 4 to 17) perforating arteries were present and in the proximity of the fibula plate. Our findings suggest the potential for iatrogenic soft tissue breakdown along the posterior border of the anterolateral surgical incision in this procedure as a result of compromised blood supply to the skin.
