ABSTRACT

INTRODUCTION: Proximal physeal fracture of the medial clavicular physis is a rare specific injury occurring in the immature skeletal. Several studies describe unilateral cases with posterior or anterior displacement and the following complications (vascular and mediastinal compression). An immediate diagnosis and management are necessary to avoid complications. The clinical diagnostic might be obvious or difficult, pain and swelling in the sternoclavicular joint area, sometimes a deformity and focal tenderness. A chest X-Ray may help and a three-dimensional reconstructed computed tomography scan has to be done to evaluate the lesions before surgery. The imaging is useful to confirm and specify the diagnostic and the displacement. PRESENTATION OF CASE: This case report presents 4 cases of proximal physeal fracture of the medial clavicular physis in 2 male-teenagers with bilateral displacement, one posterior and the other asymmetric. DISCUSSION: After reviewing the literature of the unilateral clavicular physeal fracture, we can conclude that the ideal management of these injuries has not been well described. An open reduction associated an osteosuture with non-resorbable suture was performed. One-year follow-up, both of them had full recovery without any functional impact or any complains. This management of the proximal physeal fracture of the medial clavicle on children shows an excellent result according our cases and the literature. CONCLUSION: The purpose of this study is to evaluate the functional impact of osteosuture in medial bilateral clavicular physeal fracture in teenagers after 1-year follow-up.

ABSTRACT

BACKGROUND: Sport participation is declining in some European countries. Previous findings recommended considering territorial specificities to adapt local sports promotion programs. However, in France, little is known about adolescents' preferences and their changes across time. This study aimed to measure preferred sports and their changes among a representative sample of adolescents of the third biggest French département. METHODS: Data were extracted from a previous cross-sectional study that used a quota sampling design to respect the proportions of advantaged and disadvantaged schools. The present study involved 744 and 938 participants, in 2001 and 2015, respectively. Adolescent preferences were calculated by sex and socioeconomic status (SES). Multiple binary logistic regressions were performed to measure changes between 2001 and 2015 by sex and SES. RESULTS: Sports preferences and their evolution differed by sex and SES. Three cases were observed: no significant change in sports preferences (low-SES boys), a sharp loss of interest for some sports (low-SES girls and high-SES boys) and a sharp loss of interest for some sports whilst others gained significant interest (high-SES girls). CONCLUSIONS: This knowledge may help the development of sport promotion programs. Future sport policies could choose to develop sports that are preferred and increasingly appreciated by adolescents.

ABSTRACT

Visual feedback is used in different research areas, including clinical science and neuroscience. In this study, we investigated the influence of the visualization of a real-time personalized avatar on gait parameters, focusing on knee flexion during the swing phase. We also studied the impact of the modification of avatar's knee amplitude on kinematic of the knee of healthy subjects. For this purpose, we used an immersive reality treadmill equipment and developed a 3D avatar, with instantly modifiable parameters for knee flexion and extension (acceleration or deceleration). Fourteen healthy young adults, equipped with motion capture markers, were asked to walk at a self-selected pace on the treadmill. A real-time 3D image of their lower limbs was modelized and projected on the screen ahead of them, as if in a walking motion from left to right. The subjects were instructed to continue walking. When we initiated an increase in the knee flexion of the avatar, we observed a similar increase in the subjects' knee flexion. No significant results were observed when the modification involved a decrease in knee flexion. The results and their significance are discussed using theories encompassing empathy, sympathy and sensory re-calibration. The prospect of using this type of modified avatar for stroke rehabilitation is discussed.

ABSTRACT

BACKGROUND: Sports practice has both benefits and physical risks. In France, data related to adolescent sports injury are rare. The main purpose of this article is to study the prevalence and risk of injuries by level of play and sports in the southeast of France. METHODS: Data collection was conducted in French schools among adolescents in 2015 and 2017 (n=1849; aged 14-19). Only sports players were included (n=1366). Two level of play were created. The low-level group included adolescents playing sport either outside or within a club, at the local level of competition or below. The high-level group included adolescents playing sport within a club at the state (regional) level of competition or higher. Odds-ratios and their 95% confidence intervals adjusted for variables selected using stepwise regression procedures were calculated to determine the injury risk of high-level athletes compared with those at low-level, in each sport. We also calculated the injury risk of each sport compared to all the other sports, by level of play. RESULTS: In almost all sports activities, the prevalence of injured athletes was higher in the high-level of play than in the low-level of play. The increase in injury risk was the highest in tennis, basketball, dance, athletics and volleyball. When comparing sports, at the lowest level, handball, boxing, soccer and gymnastics practitioners were more at risk than the rest of the sample. At the highest level of play, only basketball players were more at-risk. Dancing is the less dangerous sport in terms of injury outcome, regardless the level. CONCLUSION: From the state level of competition, injury risk increases significantly across most of the sports. Meanwhile, differences appeared regarding the prevalence, severity and nature of the sustained injuries. It would be useful to perform such analysis on a greater sample size, ideally representative of the national population of adolescents.

ABSTRACT

QUESTIONS/PURPOSES: Adolescent idiopathic scoliosis is a 3D spine deformity that worsens during the whole growth. New methods for spinal growth modulation with flexible spinal implants have been described to avoid progression of the deformity during growth spurt. The main limitations are that no specific ancillaries and devices are available, which makes the surgery technically demanding. METHODS: We have developed a new method of spinal growth tethering using minimal invasive videothoracoscopic approach. Fixation is performed with staples and synthetic ligament on the lateral aspect of vertebral bodies on main curvature convexity. Patients with progressive thoracic idiopathic scoliosis despite the brace treatment were included. The clinical and radiological examinations were compared before and 2 years after surgery. RESULTS: Six patients with flexible thoracic curves with a mean age 11.2 ± 1.2 years and a mean Cobb angle 45° ± 10° (35-60) were operated. All were skeletally immature. At last follow-up, the Cobb angle was stable. None of the patient underwent fusion. CONCLUSIONS: The procedure allowed a stabilization of the deformity during growth spurt. Validated devices and further studies with longer term follow-up are needed to confirm the efficiency of this technique. This small cohort of patients is a source of reflection for further medical devices developments. LEVEL OF EVIDENCE: Level 4 case series comparing to not randomized studies.

ABSTRACT

INTRODUCTION: The objective of the present study was to assess, at skeletal maturity, the efficacy of non-operative treatment by isolated nighttime brace in the prevention of progression of progressive idiopathic scoliosis of less than 25°. HYPOTHESIS: Isolated nighttime brace treatment is effective in the prevention of progression of mild progressive idiopathic scoliosis (Cobb<25°). MATERIAL AND METHODS: A single-center retrospective study included 142 patients managed by nighttime brace for progressive idiopathic scoliosis with Cobb angle<25°, with assessment at skeletal maturity. Mean Cobb angle at start of treatment was 15.5° (range, 10-25°). Mean values for Cobb angle and sagittal parameters before treatment and at skeletal maturity were compared on Student t-test. Change in Cobb angle over time was also analyzed. RESULTS: Mean Cobb angle at skeletal maturity was 16.3°, showing significant increase over baseline (15.5°; P=0.04), although the difference was less than the uncertainty of measurement (±6°). In baseline Risser 0 or 1, mean change in Cobb angle at skeletal maturity (16.2°) was not significant (P=0.1). Cobb angle diminished in 26 cases (18%), increased in 24 (17%) and was unchanged in 92 (65%). CONCLUSION: The present study confirmed the efficacy of non-operative treatment by nighttime brace in mild progressive idiopathic scoliosis (<25°) in a large majority of cases. A nighttime brace thus seems to be an effective option for the treatment of adolescent scoliosis, ensuring a safe curve of around 20°. LEVEL OF EVIDENCE: Level IV, retrospective study.

ABSTRACT

Elbow injuries are frequent but occult fractures are difficult to diagnose on x-rays. However, any delay in the diagnosis may severely impair the prognosis of some fractures. Simple tips may help the clinician read x-rays properly and avoid the classical pitfalls of elbow injuries in children. The chronology of appearance of ossification nuclei around the elbow is important to distinguish normal features from abnormality. Drawing simple geometric constructions on the x-rays may clarify most occult elbow fractures in children.

ABSTRACT

Amputation of a limb is always perceived as a catastrophe. The principles underlying creation of a stump adapted to modern prosthetic fittings must be fully understood and the patient managed by a multidisciplinary team. In paediatric patients, preserving residual limb length is a crucial point that should be assessed according to the expected growth potential. Advances in prosthetic fittings have led to changes in the overall concept of socket design, which seeks to achieve three objectives: to maximise the weight-bearing surface area, to eliminate friction of the skin on the socket, and to eliminate lever-arm effects. The introduction on the market of new materials has contributed substantially to advances in prosthetic fittings. These advances require the use of new criteria for stump quality and optimisation, which exert a considerable influence on prosthesis function. Prosthetic fitting and specific management of psychological and social problems are provided during an inpatient stay in a physical medicine department, by a team of physicians, other healthcare professionals, social workers, and educators. Three-dimensional imaging and gait analysis provide valuable information.

ABSTRACT

INTRODUCTION: The northern French Alps emergency network (RENAU) manages emergent care and patient treatment pathways in a three-county area in the French Alps. The aim of the study was to describe the pediatric activity in mobile intensive care units (MICUs). METHOD: This retrospective observational study was conducted from 1 January to 31 December 2012. Data were obtained from patients' medical records in seven representative MICUs of the RENAU. Consecutive patients between 1 month and 18 years of age were enrolled. RESULTS: During the study period, MICUs carried out 11,951 primary transports and 3087 secondary transfers. A total of 1325 patients were enrolled: 1087 primary transports and 238 secondary transfers. In primary interventions, 531 (48.9%) patients were managed for a trauma, 118 (11%) children were discharged and stayed home, 427 (39.9%) underwent an intravenous cannulation and 27 (2.5%) on-scene intubation. A pediatrician was in charge of 64 (26.9%) secondary transfers. Among 1649 (18%) mountain rescues, 296 (18.7%) involved a child. CONCLUSION: Emergency physicians in MICUs are involved with children's prehospital care and need dedicated materiel and special training.

ABSTRACT

BACKGROUND: The conventional approach for MRI procedures in very young children is to use general anesthesia which comes with inherent risks. Non-pharmacological strategies to reduce anxiety in children have also been described, but they all require patient cooperation. The purpose of the study was to evaluate the ability to complete diagnosis using temporary spica cast immobilization (TSCI) in children less than 3 years old undergoing MRI procedures for lower limb disorders. MATERIALS AND METHODS: A retrospective review identified 14 children under 3 years old that had required an MRI for a lower limb disorder, using TSCI. The MRI procedure was performed for evaluation of hip dysplasia, bone infections, limping, evaluation of soft tissue tumor and femoral head osteonecrosis. A spica cast was fitted by the pediatric orthopedic team. The MRI procedure was subsequently performed. RESULTS: Diagnosis was achieved in all cases. The radiologist identified movement artifacts (14 %) that did not impair the image quality enough to prevent interpretation. CONCLUSION: TSCI is a safe, effective and costless procedure avoiding general anesthesia for young patients under 3 years old who require MRI for pelvis or lower limb disorders. LEVEL OF EVIDENCE: IV.

ABSTRACT

INTRODUCTION: Early detection of spine fractures in children is difficult because the clinical examination does not always raise worrisome symptoms and the vertebrae are still cartilaginous, and consequently incompletely visualized on routine X-rays. Therefore, diagnosis is often delayed or missed. HYPOTHESIS: The search for a "breath arrest" sensation at the moment of the trauma improves early detection of thoracolumbar spine fractures in children. MATERIALS AND METHODS: This was a prospective monocentric study including all children consulting at the paediatric emergency unit of a single university hospital with a thoracolumbar spine trauma between January 2008 and March 2009. All children had the same care. Pain was quantified when they arrived using the visual analog scale. Clinical examination searched for a "breath arrest" sensation at the moment of the trauma and noted the circumstances of the accident. X-rays and MRI were done in all cases. RESULTS: Fifty children were included with a mean age of 11.4 years. Trauma occurred during games or sports in 94% of the cases. They fell on the back in 72% cases. Twenty-three children (46%) had fractures on the MRI, with a mean number of four fractured vertebrae (range, 1-10). Twenty-one of them (91%) had a "breath arrest" sensation. Fractures were not visualized on X-rays in five cases (22%). Twenty-seven children had no fracture; 19 of them (70%) did not feel a "breath arrest". Fractures were suspected on X-rays in 15 cases (56%). DISCUSSION: The search for a "breath arrest" sensation at the moment of injury improves early detection of thoracolumbar spine fractures in children (Se=87%, Sp=67%, PPV=69%, NPV=86%). When no fracture is apparent on X-rays and no "breath arrest" sensation is expressed by the child, the clinician can be sure there is no fracture (Se=26%, Sp=100%, PPV=100%, NPV=53%). LEVEL OF EVIDENCE: Level III.

ABSTRACT

INTRODUCTION: The natural progression of neuromuscular diseases results in inevitable musculotendinous contractures, most often in spite of early treatment. Surgery corrects this. The aim of this study was to evaluate the results of tendon surgery in these cases. MATERIALS AND METHODS: Twenty children with muscular dystrophy underwent hip surgery (tensor fascia lata tenectomy, rectus femoris and sartorius tenotomy), knee surgery (gracilis, semitendinosus and semimembranosus tenotomies) and/or ankle surgery (lengthening or tenotomy of the Achilles tendon with or without posterior tibial tendon transfer). Articular range of motion was evaluated preoperatively, 6 months after surgery, at 1 year and at the final follow-up (7.4 years). RESULTS: Three children underwent surgery before they had lost their walking capacity, eight soon afterwards, and nine long afterwards. Surgery was bilateral in all cases: 38 hips, 12 knees and 36 ankles with 22 posterior tibial tendon transfers. Hip extension, which was limited by a 30° flexion contracture improved to 10° and stabilized at 14° at the final follow-up. Adduction which was -19° before surgery increased to 35° and had stabilized at 32° at the final follow-up. Knee flessum (38°) was only slightly improved (24°) and had regressed at the final follow-up. Equinus deformity (42°) was corrected to 9° of dorsal flexion with a slight loss (2°) at the final follow-up. Varus was improved from 11° to 6°, but this had regressed at 1 year (10°) and at the final follow-up (11°). Achilles tendon tenotomies resulted in 28° of dorsal flexion at 6 months compared to 20° with lengthening. Correction of varus was better with posterior tibial tendon transfer at 6 months, 1 year and at the final follow-up (11° versus 5°). In the three patients who underwent surgery before losing their walking ability, one continued walking for 1 year and two for 6 months. None of the eight patients who underwent surgery soon after losing ambulation were able to regain walking. All patients were able to continue device assisted upright positioning for a mean 3 years. DISCUSSION: Hip and ankle surgery can release contractures. In the knees, surgery should be restricted to cases with knee flessum greater than 30°. The best results are obtained with extensive m. tensor fascia lata tenectomy and posterior tibial tendon transfer. Achilles tendon tenotomy results in better recovery of dorsal flexion. Surgery is indicated when contractures are severe and the patient is no longer able to walk. The aim should not be to continue walking but to release contractures, so that the patient can continue assisted upright positioning as long as possible. Especially in cases of asymmetric contractures, surgery can help slow the progression of scoliosis.

ABSTRACT

Data from a representative sample of 2474 French youth show that, despite a 7-year French Ministry of Health strategy for nutrition and physical activities, adolescents' motivation to practise sports and physical activities decreased significantly between 2001 and 2008. While this paper focuses on the context of physical activity in France, the general discussion may be applicable to other countries concerned with the obesity pandemic.

ABSTRACT

This study analyses how three French daily newspapers (Liberation, Le Monde, Le Figaro) convey information on the risks associated with mobile phone use in the period from 1995 to 2002. Quantitatively, the physical risks inherent to the low-intensity, electro-magnetic waves are most frequently reported, followed by those linked to mobile phone use while driving. "Social" risks, such as those related to noise or uncivil behaviour, are amongst the most rarely communicated. In general, the media present two types of physical risks connected to mobile phone use: the collective ones, which cover the low-intensity electro-magnetic waves which are emitted from the antennas on signal base stations, and the individual ones, which concem the waves produced by the mobile phone itself, and the danger associated with its use by a driver while operating a motor vehicle. Controversy surrounding the current scientific studies and the uncontrollable character of the risks linked to the low-intensity, electro-magnetic waves instill much more fear and debate than around those related to the combination of driving while talking on the telephone. While this latter point is scientifically proven, it is also subjectively under control.

ABSTRACT

Talus bipartitus is an exceptional congenital malformation consisting in the presence of two non-fused bony talar fragments. We report the case of an adolescent girl who complained of mechanical pain in the left ankle which became increasingly invalidating. Plain radiographs, CT-scan and MRI led to the diagnosis of this congenital anomaly: talus bipartitus. Surgical correction by subtalar arthrodesis provided improvement at the cost of reduced ankle mobility. Surgical treatment should be proposed for talus bipartitus in patients with invalidating pain or stiffness when rehabilitation fails to provide sufficient improvement.

ABSTRACT

We present our experience with a management of seat-belt syndrome in three children and draw particular attention to the severity of two-point fixation seat-belt injuries after a motor vehicle accident with 5 passengers whose vehicle was struck head-on by an oncoming vehicle. The parents were sitting in front, Adeline had a 2-point lap seat-belt, the 2 other children had 3-point seat-belts. The parents both had humerus fractures. The 4-year-old brother suffered a cervical and abdominal trauma with renal and splenic contusions and intestinal perforations. Adeline suffered multiple injuries, notably to the head, spine and abdominal viscera with erosions at the site of lap-seat-belt contact. The spinal injury was an L2 angular Chance fracture associated with paraplegia on the 7th day. Operative findings included a transverse tear of the left rectus abdominus muscle, an incomplete transection of the stomach and perforation of the ileum. The injuries were ultimately fatal. Given associated abdominal pain, skin erosions at the site of seatbelt contact, spinal fracture, and rectal muscle disruption apparent on emergency laparotomy, early diagnosis is important for better prognosis.
