Diagnosis and Treatment of Apophyseal Injuries of the Pelvis in Adolescents

An avulsion fracture occurs when the growth plate of an apophysis is injured due to a sudden and forceful contraction of the attaching musculotendinous unit. Usually it is adolescents who sustain these injuries, and a significant male preponderance has been found. Even though apophyseal fractures have been described in a variety of locations, the apophyses of the pelvis and hip are more prone to these injuries. Due to their rarity, avulsion fractures of the pelvis are often misdiagnosed. Additionally, patients can present late, and other pathologies are suspected initially. In most acute cases conservative treatment is successful. However, some cases require operative intervention. To plan an optimal treatment regimen, it is important to be familiar with the typical pathomechanism, the typical clinical findings, and the most commonly applied imaging modalities of these injures. The present review analyzes the currently available literature on the most frequently encountered apophyseal injuries of the pelvis in adolescent patients. Some case examples are also presented.

Injuries in physically disabled children.

Disability is a condition or function that is judged to be significantly impairing relative to the usual standard of an individual or group. The spectrum of musculoskeletal disabilities in children is immense and varied. Musculoskeletal disabilities are congenital or acquired; they affect a child partially or generally and can occur as a permanent or transient disability.Although injuries still represent a major concern for children and adolescents worldwide, studies focusing on injuries in physically disabled children are lacking. To detect musculoskeletal injuries, radiographs are frequently required. In disabled children the radiographic findings can detect the skeletal injury but also can present special radiographic findings of the underlying disease.This review offers an overview of different musculoskeletal disabilities and their related injuries as well as characteristic findings on radiographs.

The epidemiology of fractures in infants – Which accidents are preventable?

INTRODUCTION In children, fractures have a huge impact on the health care system. In order to develop effective prevention strategies exact knowledge about the epidemiology of fractures is mandatory. This study aims to describe clinical and epidemiological data of fractures diagnosed in infants. METHODS A retrospective analysis of all infants (children<1 year of age) presenting with fractures in an 11 years period (2001-2011) was performed. Information was obtained regarding the location of the fractures, sites of the accident, circumstances and mechanisms of injury and post-injury care. RESULTS 248 infants (54% male, 46% female) with a mean age of 7 months presented with 253 fractures. In more than half of the cases skull fractures were diagnosed (n=151, 61%). Most frequently the accidents causing fractures happened at home (67%). Falls from the changing table, from the arm of the care-giver and out of bed were most commonly encountered (n=92, 37%). While the majority of skull fractures was caused from falls out of different heights, external impacts tended to lead to fractures of the extremities. 6 patients (2%) were victims of maltreatment and sustained 10 fractures (2 skull fractures, 4 proximal humeral fractures, 2 rib fractures, and 2 tibial fractures). CONCLUSION Falls from the changing table, the arms of the caregivers and out of bed caused the majority of fractures (especially skull fracture) in infants. Therefore, awareness campaigns and prevention strategies should focus on these mechanisms of accident in order to decrease the rate of fractures in infants.

The impact of arterial vessel injuries associated with pediatric supracondylar humeral fractures.

BACKGROUND Pediatric supracondylar humeral fractures are regularly complicated by vascular compromise. However, the treatment regimen for pulseless hands with good capillary refill time is discussed controversially. The aim of the present study was to present our treatment strategy in a series of children sustaining supracondylar humeral fractures associated with impaired peripheral blood flow. METHODS Medical charts of all children sustaining supracondylar humeral fractures treated between 1995 and 2009 were reviewed. Treatment and the course of patients with impaired peripheral blood flow were evaluated. Patients were invited for a follow-up examination. RESULTS Forty of 499 patients sustaining a supracondylar humeral fracture presented with peripheral pulselessness. Two children underwent immediate vascular surgery. In the remaining 38 patients, the fracture was reduced, followed by a re-evaluation of the peripheral circulation. Twenty-four of those patients had normal peripheral pulse and capillary refill time, and no further therapy was necessary. Fourteen patients had a persisting absent peripheral pulse after fracture reduction. While in 4 of those patients—including 3 patients with prolonged peripheral capillary refill time—vascular surgery was performed, 10 patients were successfully treated with “watchful waiting.” At follow-up of 3.5 years (range, 2–6 years), the performed diagnostic workup including capillary refill time and blood pressure was without pathologic findings in all patients. CONCLUSION Our data suggest that blood flow often recovers following reduction of supracondylar fractures with impaired peripheral vascularization. In cases of a “pink pulseless hand” (absent peripheral pulse and good peripheral capillary refill time), “watchful waiting” instead of immediate surgical exploration might be a treatment option. However, further studies with more patients have to be conducted to formulate a recommendation for the treatment of these severe injuries. LEVEL OF EVIDENCE Therapeutic study, level V.

The pediatric knee: diagnosis and management of ligament injuries.

In the last few decades, sports injuries in pediatric and adolescent athletes have increased dramatically, with ∼ 38 million young athletes participating in organized sports annually in the United States. Starting at the age of 2 years, an increase of the incidence of knee injuries until adulthood with a peak at 6 and at 13 years of age has been observed. Due to a physiologic laxity of the ligaments, ligament injuries are uncommon in these patients, but they are getting more frequent. In the growing knee, open physis are the points of minor resistance. Therefore apophyseal injuries of the pediatric knee are more common. Diagnostics and treatment of ligament injuries of the pediatric and adolescent knees are challenging. This article presents an overview of ligament injuries in the pediatric and adolescent knee, their diagnostic work-up, and their treatment in the growing patient.

Computed tomographic scan in head trauma: what is the rational in children?

Traumatic brain injury (TBI) is the consequence of external forces that traumatically injure the brain. Closed head injury is common in children and is estimated to result in 650,000 to 1 million emergency department visits annually with approximately 7,400 deaths in the United States. Mild TBI is the most common form of closed head injury and constitutes 80 to 90% of all the TBI. Cranial computed tomography (cCT) is performed in usually more than 50% of the patients, thus, resulting in an extreme overuse with the inherent risk for inducing malignancies. The purpose of this article is to review current approaches, recommendations, and guidelines on pediatric head trauma with special emphasis on cCT. Therefore, after an overview on classification and TBI scores, diagnostic imaging, and management rules for clinical important TBI, as well as own experience including remarks on cCT technique will be discussed.

Management des Polytraumas bei Kindern und Jugendlichen

ZusammenfassungKinder und Jugendliche unterscheiden sich in der Versorgung schwerer Mehrfachverletzungen signifikant von Erwachsenen. Daher sind kindgerechte Versorgungsstrukturen erforderlich, die neben einer adäquaten technischen und personellen Ausstattung auch spezielle, für Kinder- und Jugendliche adaptierte Versorgungsstrategien anbieten. Auf Strahlenhygiene in der Abklärung eines Polytraumas muss trotz der oft komplexen Verletzungsmuster Rücksicht genommen werden. Der Ultraschall nimmt daher in der Abklärung eventueller Abdominaltraumata einen hohen Stellenwert ein. Die Verfügbarkeit von Spezialisten anderer Fachgebiete in einem respektvollen interdisziplinären Umfeld garantiert eine optimale Versorgungsqualität beim kindlichen Polytrauma.

Post-traumatic and Post-surgical Chest Wall Deformities (Acquired Chest Wall Deformities)

Chest wall deformities can be acquired after trauma to the chest as well as after intervention in the thorax using open procedures that violate the bony structures of the thoracic wall altering their growth pattern. This chapter explains the embryological as well as the development of the thoracic cage and interventions which can alter the proportional chest wall growth. Explanations have been provided as to how the bone alterations differ from the cartilage alteration in their manifestation of chest wall deformities.
