Leading an Organization in the 21st Century: The Importance of Environmental Sustainability, Social Responsibility, and Good Governance.

The concept of environmental sustainability, social responsibility, and good governance (ESG) is now well established in the corporate world and in for-profit organizations. However, it is not a concept that has reached medical and surgical association boardrooms in a meaningful way. It is important to define the concept of physician and corporate author expertise and objectives of ESG, provide a rationale for using ESG within orthopaedic organizations, and identify specific areas (primarily the "S" and the "G") where the American Academy of Orthopaedic Surgeons and other groups can align with this strategy.

Developmental Dysplasia of the Hip From Birth to Adolescence: Clear Indications and New Controversies.

It is important to be knowledgeable about the latest information on the diagnosis and the evidence-based management of developmental hip dysplasia and dislocation from birth through adolescence. The focus should be on the effect of the problem; normal growth and development of the hip joint; and the pathoanatomy, natural history, and long-term outcomes of developmental dysplasia of the hip, hip subluxation, and dysplasia. Many controversies exist in the management of this complex spectrum of disorders.

How and When to Transition to the Next Phase: Reflections.

With Americans living longer, many physicians and surgeons have extended their medical and surgical practice life beyond the traditional 65-year-old retirement age. As retirement is inevitable, planning for that eventuality, which in early practice years appears unnecessary, is in fact an exercise which will pay dividends at the time of retirement. Two senior orthopaedic surgeons provide insight on the 2 main issues concerning retirement: how to prepare for retirement while in active practice, and factors to consider as to the timing of that major life event.

Deformity correction using proximal hooks and distal screws (PHDSs) improves radiological metrics in adolescent idiopathic scoliosis.

PURPOSE: Surgical correction for AIS has evolved from all hooks to hybrids or all screw constructs. Limited literature exists reporting outcomes using PHDS for posterior spinal fusion (PSF). This is the largest series in evaluating results of PHDS technique. METHODS: A retrospective review of consecutive AIS patients undergoing PSF by a single surgeon between 2006 and 2015 was performed. All eligible patients met a minimum 2-year follow-up. Patient demographics and radiographical parameters (radiographic shoulder height (RSH), T1 tilt, clavicle angle) at baseline, 6-week and 2-year post-operation were recorded. The primary outcome was difference in RSH from baseline measurements evaluated using repeated measures one-way analysis of variance with Bonferroni correction. RESULTS: A total of 219 patients (mean age at surgery: 13.68 years; 82% female) were included. The mean follow-up was 41.2 months (range 24-108 months). The RSH was significantly improved from - 14.7 ± 10.38 mm to 8.0 ± 6.9 mm (P < 0.0001). Clavicle angle was improved from 2.13° to 1.31° (P < 0.0001). T1 tilt was improved from 5.6° to 2.2° (P < 0.0001). At last follow-up, 95.8% of patients were shoulder balanced. There was a significant improvement of Cobb angle with an average correction of the upper thoracic curve of 42% and main thoracic curve of 67%. CONCLUSION: The PHDS demonstrates the potential for additional shoulder balance improvement. Extension of fusion to structural proximal thoracic spine is the key to success for shoulder balance. It remains to be seen whether these improvements will translate into improved clinical outcomes in the longer term.

Developmental Dysplasia of the Hip From Birth to Arthroplasty: Clear Indications and New Controversies.

Developmental dysplasia of the hip is the all-encompassing term used to describe the wide spectrum of disorders of the development of the hip that manifest in various forms and at different ages. Developmental dysplasia of the hip often evolves over time because the structures of the hip are normal during embryogenesis but gradually become abnormal. Such variability in pathology is associated with a similarly wide range in management options and recommendations aimed at preventing hip joint arthrosis. These options may be instituted at any time between birth and adulthood as techniques aimed at preserving the native hip or replacing the arthritic hip. Many of these management options are clearly indicated and considered standard practice. However, with the evolution of the understanding of hip biomechanics, better knowledge of the long-term outcomes of hip joint-preserving surgeries, and ever-improving technology influencing hip arthroplasty come new controversies, especially whether to preserve or replace the mature hip.

Ruptured Appendicitis and Retrocecal Abscess Masquerading as Knee Pain in a Pediatric Patient: A Case Report.

BACKGROUND: Knee pain has a variety of etiologies in the pediatric population, including septic arthritis, osteomyelitis, fracture, ligamentous injury, and neoplasms. Extrinsic sources of knee pain may also be intra-abdominal, although abdominal pathology is much more likely to manifest as hip or proximal thigh musculature pain. CASE REPORT: A 5-year-old healthy male presented with atraumatic right knee pain, discomfort with weightbearing, fever, and elevated inflammatory laboratory markers. Physical examination and magnetic resonance imaging findings of the knee were benign, leading to low clinical suspicion for knee septic arthritis. Blood cultures were positive for a gastrointestinal organism, Granulicatella adiacens, suggesting abdominal pathology leading to referred pain. Ultrasound evaluation and computed tomography (CT) of the abdomen revealed a large abscess secondary to perforated appendicitis, which was treated with CT-guided drainage and i.v. antibiotics. The patient's musculoskeletal pain subsided with treatment of the appendicitis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Acute appendicitis may present as knee pain, with other signs and symptoms mimicking septic arthritis, such as fever, inability to bear weight, and elevated inflammatory markers. Considering an array of differential diagnoses in pediatric patients with apparent knee septic arthritis is crucial to prevent delay in diagnosis of alternative infectious sources.

The Importance of Natural History.

In a traditional view, the natural history of a condition or a disease tells us of the adult consequences of that entity, be it benign or otherwise. This knowledge then provides guidance as to who needs treatment, and allows us to assess whether our treatments alter an otherwise adverse natural history in a positive way without introducing iatrogenic complications. However, in the new paradigm for health care delivery of value-based care, we need to be able to express natural history in additional terms of burden of disease. This is something that lawmakers and people who pay for health care can understand and has a comparative value. It also serves as a benchmark to show the effectiveness of interventions aimed at reducing disease burden. In this paper, I will discuss why this POSNA symposium is important and make some recommendations on directions where we as individuals and as a professional society should be putting in our efforts and resources.

The Natural History of Adolescent Idiopathic Scoliosis.

INTRODUCTION: Adolescent idiopathic Scoliosis (AIS) affects 2% to 3% of the population of which only 0.3% to 0.5% of affected patients will have a curvature of >20 degrees, the curve magnitude at which treatment is generally recommended. For AIS the current natural history data is limited and most of the information comes from a small body of literature from the University of Iowa. METHODS: The Iowa natural history studies began as retrospective reviews but beginning in 1976, the cohort was followed prospectively. Outcomes assessed in this group of patients included; mortality, pulmonary function, pregnancy-(effect of pregnancy on scoliosis and the effect of scoliosis on pregnancy), radiographic, curve progression, and osteoarthritis. In addition, validated questionnaires were used to evaluate back pain, pulmonary symptoms, general function, depression, and body image. RESULTS: Patients with untreated AIS can function well as adults, become employed, get married, have children, and grow to become active older adults. Unfortunately, untreated scoliosis may lead to increased back pain and pulmonary symptoms for patients with large thoracic curves. Patients with untreated AIS can also develop substantial deformity, and the cosmetic aspect of this condition cannot be disregarded. CONCLUSIONS: The summary findings of this unique lifetime natural history of AIS patients provides patients and parents a solid evidence base upon which to make informed decisions.

The 2018 Nicholas Andry Award: The Evidence Base for the Treatment of Developmental Dysplasia of the Hip: The Iowa Contribution.

This review summarizes evidence developed at the University of Iowa concerning the management and outcomes of developmental dysplasia of the hip beginning with the observations and analyses of Dr Arthur Steindler in the early 1900s. The strong evidence-based practice tradition established by Steindler 100 years ago continues as we critically evaluate our procedures and patient outcomes, only altering approaches when warranted by strong personal and research evidence. Our practice continues to be conservative in that we strive to produce the best environment possible for the hip to develop on its own and operate only when less invasive methods have failed.

What Does a Shoulder MRI Cost the Consumer?

BACKGROUND: More than 100 MRIs per 1000 inhabitants are performed in the United States annually, more than almost every other country. Little is known regarding the cost of obtaining an MRI and factors associated with differences in cost. QUESTIONS/PURPOSES: By surveying all hospital-owned and independent imaging centers in Iowa, we wished to determine (1) the cost to the consumer of obtaining a noncontrast shoulder MRI, (2) the frequency and magnitude of discounts provided, and (3) factors associated with differences in cost including location (hospital-owned or independent) and Centers for Medicare & Medicaid Services designation (rural, urban, and critical access). METHODS: There were 71 hospitals and 26 independent imaging centers that offered MRI services in Iowa. Each site was contacted via telephone and posed a scripted request for the cost of the technical component of a noncontrast shoulder MRI. Radiologists' reading fees were not considered. Statistical analysis was performed using standard methods and significance was defined as a probability less than 0.05. RESULTS: The mean technical component cost to consumers for an MRI was USD 1874 ± USD 694 (range, USD 500-USD 4000). Discounts were offered by 49% of imaging centers, with a mean savings of 21%. Factors associated with increased cost include hospital-owned imaging centers (USD 2062 ± USD 664 versus USD 1400 ± USD 441 at independent imaging centers; p < 0.001; mean difference, USD 662; 95% CI, USD 351-USD 893) and rural imaging centers, unless designated as a critical access hospital (USD 2213 ± USD 668 versus USD 1794 ± USD 680; p = 0.0202; mean difference, USD 419; 95% CI, USD 66-USD 772). CONCLUSIONS: In Iowa, the cost to the consumer of a shoulder MRI is significantly less at independent imaging centers compared with hospital-owned centers. Referring physicians and healthcare consumers should be aware that there may be substantial price discrepancies between centers that provide advanced imaging services.
