Avulsion fractures of the pelvis are a relatively common injury in children. The most common avulsion injuries in the pelvis occur at the ischial tuberosity hamstring and adductor tendon attachment and the anterosuperior iliac spine quadricepsrectus femoris attachment Herring, 2. Figure 1. A and B. They can also occur at the iliac crest and at the lesser trochanter of the femur iliopsoas attachment. An understanding of the diagnosis and treatment of tibial shaft fractures is of importance to primary care physicians and orthopedic surgeons alike. Often.

A Randomized Trial of Vertebroplasty for Osteoporotic Spinal Fractures. David F. Kallmes, M. D., Bryan A. Comstock, M. S., Patrick J. Heagerty, Ph. D. The British Journal of Medical Practitioners has adopted a Continuous Publication model from the beginning of year 2010 publishing articles online as soon as. The highest incidence of pelvic avulsion fractures occurs in boys between the age of 1. Sunder Carty, 1. The most frequent cause of injury is a sudden forceful muscle contraction such as making a quick turn, kicking a ball, or sprinting. The powerful contraction of the attached muscle will often cause an avulsion of the muscle from the bone. Although acute avulsion fractures of the pelvis are more common, chronic repetitive trauma can also cause a similar injury. Overuse injuries of the hip in adults often lead to a tendonitis or a bursitis, whereas an apophysitis or avulsion injury is much more common in children and adolescents see Figure 2. A physical examination usually reveals localized tenderness at the avulsion site. Pain is also aggravated by passive motion of the hip that places tension on the attached muscle i. Patients also frequently demonstrate an antalgic gait and have pain during their activity or sport. An anteroposterior radiograph of the pelvis usually reveals the avulsed fragment. Comparative views of the contralateral side are often helpful in confirming the diagnosis and avoiding further unnecessary advanced imaging studies. This injury is usually treated symptomatically and often involves rest, application of ice, and relaxation of the involved tendon OKane, 1. Conservative treatment of pelvic avulsion fractures is usually successful. Crutches are often needed for several weeks to reduce symptoms and rest the extremity involved. Complications following pelvic avulsion fractures in children are rare, and most patients will have decreased symptoms in approximately 2 4 weeks. To avoid reinjury or chronic apophysitis, the injury should heal completely before the patient returns to normal activities. This will often require 2 3 months of activity modificationsrest from the sport. A physical therapy program with conditioning, strengthening, and gentle stretching is often needed prior to resuming competitive sports Boyd, Peirce, Batt, 1. Nurses and nurse practitioners can have a key role in educating both patients and parents about the importance of rest from activity with this type of injury. With the increasing expectations among higher levelelite athletes, orthopaedic surgeons may occasionally consider operative intervention for larger, displaced pelvic avulsion fractures. However, numerous studies have failed to substantiate improved outcomes with surgical fixation of the avulsion fragment Cimerman, Smrkolj, Veselko, 1. Rosenberg, Noiman, Edleson, 1. Sunder Carty, 1. Femoral Neck Fractures. Handbook Of Environmental Psychology 2002 on this page. Femoral neck fractures are an uncommon injury in children approximately 1 of all pediatric fractures and are usually associated with high energy trauma. This is in marked contrast to hip fractures in elderly patients, in whom minor torsional forces acting on osteoporotic bone can often cause a hip fracture. Common mechanisms of injury in children include a fall from a height, a pedestrian versus motor vehicle collision, a motor vehicle crash, or a fall from a bicycle. When assessing a young patient with a known or suspected femoral neck fracture, providers must always rule out nonmusculoskeletal injuries to the chest, head, or abdomen. Femoral neck fractures can also be seen occasionally in young patients with fibrous dysplasia, osteogenesis imperfecta, or large unicameral bone cysts which weakens the surrounding bone. They are also seen in patients with neuromuscular disease and underlying osteopeniaosteoporosis. If the trauma is significant, but the history is not consistent, nonaccidental trauma NAT should always be considered Swischuk, 2. Proximal femur fractures in children have a relatively high complication rate and require urgent referral to a pediatric orthopaedic specialist for definitive operative management. Femoral neck fractures are frequently classified into four types depending on their location Delbet, 1. A type I fracture is a transepiphyseal separation of the femoral head. This is the least common type of proximal femur fracture in children Herring Mc. Carthy, 1. 98. 6. This fracture is very difficult to appreciate in newborns and infants because the femoral head is unossified and cannot be seen on radiographs. Type I fractures can be associated with nonaccidental abusetrauma, especially in the infant and toddler population Staheli, 2. With this type of femoral neck fracture, there is an associated dislocation of the femoral head in nearly 5. With a concurrent femoral head dislocation, there is nearly 1. AVN and premature physeal closure with this fracture Gray, 2. A type II femoral neck fracture occurs at the transcervical region midportion of femoral neck. This is the most common type of femoral neck fracture, accounting for approximately 4. Gerber, Lehmann, Ganz, 1. Figure 3. This type of femoral neck fracture also has a very high association with secondary AVN of the femoral head approximately 5. Type III fractures occur at the cervicotrochanteric region of the proximal femur base of the femoral neck. The overall reported incidence of this femoral neck fracture is between 2. AVN occurring in approximately 2. Herring, 2. 00. 2. A type IV femoral neck fracture occurs at the intertrochanteric region between the greater and lesser trochanter. Overall, these fractures are much less common and have a much lower incidence of AVN approximately 1. Children with femoral neck fractures will usually hold the hip in a fixed position with varying amounts of external rotation, abduction, and flexion. On physical examination, this position allows for maximum relief of hip irritability due to capsular distention by fracture hematoma Shah, Eissler, Radomisli, 2. In general, the patient will be unable to move the hip actively or bear weight on the affected side. Anteroposterior and lateral if tolerated radiographs should be obtained and the patient should be referred urgently to a pediatric orthopaedic surgeon for definitive management. Treatment of pediatric femoral neck fractures depends upon the age of the child, the type of fracture, and the amount of displacement of the fracture Herring, 2. The overall goal of treatment is to provide fracture fragment stability through an anatomic reduction while avoiding complications that are common with this injury. Nearly all pediatric femoral neck fractures are now treated in the operating room under general anesthesia and fluoroscopic guidance. Following closedopen reduction of the fracture, the surgeon will often need to place internal fixation to prevent displacement see Figure 4. In younger children, many surgeons will use smooth pins for fixation. They will then supplement it with a spica body cast and immobilize the patient for approximately 6 8 weeks. Smooth pins are usually used in the younger pediatric population as they can cross the physis with a relatively low incidence of subsequent growth arrest.
