It is unlikely that topography will supplant radiography for the ascertainment of Cobb angles, because the error margins of both are wide, and the two are not measuring the same aspect of the deformity. The Quantec system is useful in patient monitoring as an alternative to radiography, without diminishing the standard of care.

This paper's identification of the classic papers of pediatric orthopaedic surgery gives us a unique insight into the development of pediatric orthopaedic surgery in the twentieth and early twenty-first centuries and identifies those individuals who have contributed the most to the body of knowledge used to guide evidence-based clinical decision-making in pediatric orthopaedics today.

Scoliosis, lateral curvature of the spine, has been studied since Hippocrates' time, but remains a disputed subject in orthopaedic surgery, because of its several varieties, unknown cause and unpredictable course. A review of 30 years' experience in a paediatric orthopaedic unit was undertaken to clarify the problem. Patient records, collected prospectively, were examined to demonstrate the incidence, prevalence, extent, course and outcome of the commonest variety, adolescent idiopathic scoliosis. Reference was made to the results of previously published studies. Records from a school screening programme showed that, while slight degrees of spinal curvature were widely prevalent in the community, these were of no clinical significance and major cosmetic deformity was rare: only 8 in 10,000 adolescent girls had Cobb angles of 40 degrees or more and only half of these underwent surgical correction. Evidence to support non-operative treatment could not be demonstrated and it did not reduce the incidence of surgical intervention. Because the course of scoliosis did not seem to correspond with much published work, or with current hypotheses of aetiology, a rethinking of the whole subject is advocated. An alternative model of pathogenesis deriving from developmental biology was proposed. While advances in surgical methods have been significant, the core problems of aetiology and natural history remain. Until they are resolved, all conclusions on management must be provisional. This is where innovative thinking needs to be directed.

Trampolines are a high-risk activity with the potential for significant orthopaedic injury. In Ireland, we have recently seen a dramatic increase in pediatric trampoline-related injuries mirroring the trend in the United States during the last 10 to 15 years. We found that more than 1 individual on a trampoline is a major risk factor for injury, where the lightest person is 14 times more likely to be injured than the heavier. The lighter person also has a greater chance of being injured with smaller numbers on the trampoline. We reiterate the American Academy of Pediatrics policy statement advice that trampolines be used only in supervised training programs--never at home, in outdoor playgrounds, or in schools. The public should be made aware of the potential dangers of trampolines through public health campaigns, radio, and television.

Hurler syndrome is an autosomal recessive metabolic storage disease. Hematopoietic stem cell transplant increases life expectancy, but the effects on associated musculoskeletal abnormalities remains unclear, and long-term data are limited. We detail the follow-up of 23 patients at a mean of 8.5 years after successful hematopoietic stem cell transplant. All patients underwent clinical examination at an annual multidisciplinary clinic. Serial radiological studies were reviewed to assess development and management of hip dysplasia and genu valgum. All patients demonstrated characteristic acetabular dysplasia and failure of ossification of the superolateral femoral head. Eight patients underwent bilateral pelvic and femoral derotation (mean age at surgery, 4.4 years); 4 patients had pelvic osteotomy only. Mean preoperative acetabular angle was 34 degrees. Genu valgum of variable severity due to failure of ossification of the lateral aspect of the proximal tibial metaphysis was observed early, and 6 patients underwent medial epiphyseal stapling, decreasing tibiofemoral angle by a mean of 8 degrees. Clinically, all patients were independently mobile, with restriction of internal hip rotation being the most significant clinical finding. Valgus knees and pronated feet were a typical finding. This cohort represents one of the largest available for study, and ongoing review will clarify the progression of musculoskeletal problems and determine the effectiveness of orthopaedic intervention.

Background Virtual fracture clinics are an alternative to the traditional model of fracture care. Since their introduction in 2011, they have become increasingly used in the United Kingdom and Ireland. The coronavirus disease 2019 (COVID-19) health crisis has driven institutions to examine such innovative solutions to manage patient care. The current controversies include quantifying safety outcomes, such as potential delayed or missed injuries, inadequate treatment, and medicolegal claims. Questions also exist regarding the potential for cost reductions and efficiencies that may be achieved. Physical distancing has limited the number of face-to-face consultations, so this review was conducted to determine if virtual fracture clinics can provide an acceptable alternative in these challenging times. Questions/purposes The aim of this systematic review was to describe (1) adverse outcomes, (2) cost reductions, and (3) efficiencies associated with the virtual fracture clinic model. Methods A systematic review of the PubMed, MEDLINE, and Embase databases was conducted from database inception to March 2020. The keywords “virtual” or “telemedicine” or “telehealth” or “remote” or “electronic” AND “fracture” or “trauma” or “triage” AND “clinic” or “consultation” were entered, using the preferred reporting items for systematic reviews and meta-analyses. Inclusion criteria included adults and children treated for injuries by a virtual clinic model at the initial review. Eligible injuries included injuries deemed to not need surgical intervention, and those able to be treated remotely using defined protocols. Exclusion criteria consisted of patients reviewed by telemedicine using video links or in person at the initial review. Initially, 1065 articles were identified, with 665 excluded as they did not relate to virtual fracture clinics. In all, 400 articles were screened for eligibility, and 27 full-text reviews were conducted on 18 studies (30,512 virtual fracture clinic encounters). Three subdomains focusing on adverse outcomes, cost reductions, and efficiencies were recorded. The term adverse outcomes was used to describe any complications, further surgeries, re-referrals back to the clinic, or deviations from the protocols. Efficiency described the number of patients reviewed and discharged using the model, savings in clinic slots, reduced waiting times, or a reduction in consumption of resources such as radiographs. All studies were observational and the quality was assessed using Newcastle-Ottawa tool, which demonstrated a median score of 6 ± 1.8, indicating moderate quality. Results Six studies reported adverse outcomes in detail, with events ranging from inappropriate splinting, deviations from protocols, and one patient underwent an osteotomy for a malunion. Efficiency varied from direct discharge proportions of 18% in early studies to 100% once the virtual fracture clinic model was more established. Cost reductions compared with estimates derived from conventional fracture clinics varied from USD 53 to USD 297 and USD 39,125 to USD 305876 compared with traditional fracture clinic visits. Conclusions Virtual fracture clinics may provide a means to treat patients remotely, using agreed-upon protocols. They have an important role in the current COVID-19 pandemic, due to the possibility to provide ongoing care in an otherwise challenging setting. More robust studies looking at this model of care will be needed to assess its long-term effects on patients, institutions, and health care systems. Level of Evidence Level IV, therapeutic study.

Although an association exists between left thoracic curves and disease, it is not strong enough to determine who should be intensively investigated, to the exclusion of other clinical findings, and it seems inappropriate for a different approach to be adopted on the basis of scoliosis pattern alone. Gender in males and age at occurrence in females are more important risk factors than in scoliosis configuration. All new cases of scoliosis treated by a physician warrant equally meticulous assessment, with more sophisticated investigative techniques where indicated by the complete clinical picture, of which curve lateralization is only a part. Biologic theories of left and right are more capable of dealing with the phenomenon of scoliosis lateralization than are simple mechanics or concepts of specific diseases.
