Purpose: The purpose of the study was to compare the post-reduction magnetic resonance imaging morphology for hips that developed residual acetabular dysplasia, hips without residual dysplasia, and uninvolved contralateral hips in patients with unilateral developmental dysplasia of the hip undergoing closed or open reduction and had a minimum 10-year follow-up.

Methods: Retrospective study of patients with unilateral dysplasia of the hip who underwent open/closed hip reduction followed by post-reduction magnetic resonance imaging. Twenty-eight patients with a mean follow-up of 13 ± 3 years were included. In the treated hips, residual dysplasia was defined as subsequent surgery for residual acetabular dysplasia or for Severin grade > 2 at latest follow-up. On post-reduction, magnetic resonance imaging measurements were performed by two readers and compared between the hips with/without residual dysplasia and the contralateral uninvolved side. Magnetic resonance imaging measurements included acetabular version, coronal/ axial femoroacetabular distance, acetabular depth-width ratio, osseous/cartilaginous acetabular indices, and medial/lateral (limbus) cartilage thickness.

Results: Fifteen (54%) and 13 (46%) hips were allocated to the "no residual dysplasia" group and to the "residual dysplasia" group, respectively. All eight magnetic resonance imaging parameters differed between hips with residual dysplasia and contralateral uninvolved hips (all p < 0.05). Six of eight parameters differed (all p < 0.05) between hips with and without residual dysplasia. Among these, increased limbus thickness had the largest effect (odds ratio = 12.5; p < 0.001) for increased likelihood of residual dysplasia.

Conclusions: We identified acetabular morphology and reduction quality parameters that can be reliably measured on the post-reduction magnetic resonance imaging to facilitate the differentiation between hips that develop with/without residual acetabular dysplasia at 10 years postoperatively.

Introduction: Proximal third diaphyseal fractures of the radius and ulna represent an onerous fracture pattern due to difficulty maintaining acceptable alignment with nonoperative management. Our aim was to identify the factors that increase the odds for a surgical treatment of these fractures. Recognizing these factors can raise awareness to patients who are more likely to require additional care and assist clinicians in counseling families, targeting treatment plans, and constructing follow-up protocols. We hypothesized that the age of the patient, the amount of initial fracture displacement, and the angulation of the fracture would predict the need for operative treatment.

Methods: We retrospectively reviewed 276 proximal third diaphyseal forearm fractures at a single tertiary care institution. All patients underwent a nonoperative treatment trial, and if failed continued to surgery. Following a univariate analysis, we constructed a binary multivariate logistic regression model that included age, initial translation, and initial angulation to assess the association between the tested variables.

Results: A regression model revealed that age (10 years and older, odds ratio: 8.2, 95% confidence interval: 3.9-17.24, p < 0.001) and radius translation of more than 100% (odds ratio: 7.06, 95% confidence interval: 2.69-18.52, p < 0.001) were associated with the need for surgical treatment. Initial fracture angulation lacked an association with a surgical treatment (odds ratio: 0.81 95% confidence interval: 0.38-1.74, p = 0.59).

Conclusion: Age above 10 years and 100% initial translation of the radius fracture increased the odds for an ultimate decision to perform a surgery. Initial angulation, although often being the most remarkable radiographic feature, was not associated with a nonoperative treatment failure. We recommend an initial reduction attempt after counseling patients and their families that there is a high rate of conversion to operative treatment when the above features are met.

Background: Osteochondritis dissecans is an acquired condition of the joint that affects the articular surface and the subchondral bone. The juvenile form of osteochondritis dissecans presents in those aged 5-16 years with open growth plates. The causes of osteochondritis dissecans are unknown.

Methods: The goals of treatment are to promote healing of the subchondral bone and prevent chondral collapse, subsequent fracture, osteochondral defect formation, and early joint degeneration. Treatment modality is influenced on clinical symptoms, skeletal maturity, as well as the size, stability, and location of the lesion. This article will review the treatment strategies of juvenile form of osteochondritis dissecans of medial femoral condyle and of atypical regions, such as lateral femoral condyle, patellofemoral joint, and tibial plateau.

Background: The incidence of meniscal tears in children has been increasing. Early sport specialization, more intense training activity, and increasing participation in competitive sports may have affected to that increasing trend. Diagnosing acute menisci tear in children is based on suggestive clinical and magnetic resonance imaging findings. There are special particulars in immature menisci, due to relatively good vascular supply. Furthermore, growing skeleton makes differences in injury pattern, and a clinician needs to recognize not only meniscus but also potential injuries in growth plates and ligaments, which are usual in connection with pediatric meniscus leasion. Clinical and imaging investigation prior to treatment is crucial, because non-operative care is considerable, to achieve spontaneous healing, especially in peripherial tears of younger children. Second, repair is preferred always as possible, in spite of resection due to high rate of long-term sequelae after partial meniscectomy. High standard preoperative imaging aid in preparing to the meniscus sparing arthroscopic intervention.

Methods: In this current concept article, the clinical considerations of imaging the injured pediatric knee with a suspected meniscus tear and the treatment options by the imaging findings are reviewed.

Background: Lateral dislocation of the patella is a common injury in children. It can occur in previously healthy and anatomically normal knees, but there are several abnormalities that predispose to patellar instability. Magnetic resonance imaging is an essential part of assessing for associated injuries and risk of further instability. Treatment aims to prevent redislocation, residual instability, osteoarthritis, and allow return to previous activities. The purpose of this review was to assess evidence for management of first-time patella dislocation in children and adolescents.

Methods: Literature review was performed, accompanied by the current best practice by the authors.

Results: Non-operative treatment is preferred, except where there are associated injuries such as osteochondral fractures that would benefit from surgery. The exact method of ideal non-operative management is not clearly defined but should focus on restoration of range of movement and strength with bracing as indicated. There seems to be a trend toward operative intervention that may well be inappropriate.

Conclusion: Further prospective studies are required with focus on the younger patient to fully understand if there is an at-risk group that would benefit from early surgery.

Purpose: Soccer is a popular sport among children and adolescents that exposes to a high risk of injury. Several prevention programs, including the FIFA 11+ Kids program have been developed to decrease this injury rate. The aim of the study was to investigate the knowledge and use of the FIFA 11+ Kids program among soccer coaches of skeletally immature soccer players in a Swiss canton and analyze difficulties of implementing such a prevention program.

Materials & methods: First, an online survey was sent to all soccer coaches involved in Swiss training programs for male players from 7 to 13 years of age. Coaches were identified through existing Swiss coaching networks. A total of 237 coaches completed the survey. Second, the FIFA 11+ Kids program was implemented in three soccer teams (players from 7 to 13 years of age) during 6 months in the same canton. Utilization of FIFA 11+ Kids program and compliance of coaches were recorded by the research staff.

Results: Around 84% of the included coaches in the survey were certified. Of those, 59% had been taught injury prevention during their course(s). Only 14% of the included coaches knew one of the FIFA programs (11, 11+, 11+ Kids), of those, about one-third (10 out of 237) used the FIFA 11+ Kids program. After 6 months, none of the soccer coaches applied the entire FIFA 11+ Kids program twice a week. One coach had completely abandoned the program. The main reasons for their disapproval were the time and surveillance needed and the players' lack of motivation. They stated, however, that the exercises were good if used occasionally.

Conclusion: Injury prevention should be integrated in every soccer coach education courses. An adaptation of the FIFA 11+ Kids program should be considered, especially for the youngest players.

Background: Anterior cruciate ligament injury in the child and adolescent patient remains a controversial topic when considering management, especially regarding surgical choices. Treatment variations are seen not just when comparing different countries but also within nations. This arises partly as contemporary treatment is mostly inferred from the adult population who physiologically and in terms of outcomes differ significantly from children. There is an increasing body of evidence for this cohort of patients who have specific challenges and difficulties when determining the optimum treatment.

Methods: Within this article, we will summarize the current evidence for surgical management of anterior cruciate ligament injury for the pediatric patient.

Results and conclusions: There remain many controversies and gaps inthe treatment of Paediatric Anterior cruciate ligament reconstruction and this high risk cohort continues to cause difficulty in identifying the best mode of surgical management.

Meniscal pathology is widely prevalent in the adult population, secondary to acute trauma and chronic degeneration. It is less commonly seen in children, although its incidence is rising. The true prevalence in children remains unknown, as pathologies such as discoid menisci often go undiagnosed, or are found only incidentally. The rising incidence can be attributed to increased participation in sports at younger ages, both in intensity and frequency, with potentially year-round competition. Meniscal tears lead to pain and mechanical symptoms in the short to medium term, but more significantly, have been shown to lead to compartmental chondral degeneration and early arthritis in the long term. With advancing arthroscopic techniques, and children's propensity for better healing, osteoarthritis secondary to meniscal pathology is a potentially preventable problem. This article discusses meniscal injuries in children and adolescents and their management.
