[Kyphosis and kyphotic posture in children and adolescents].

Kyphosis is a sagittal deviation of the spine that presents as an anterior spinal curvature. It is a frequent reason for consultation during adolescence. It is necessary to know how to differentiate between a simple postural kyphosis that is flexible and reducible, and requires no further investigation, from a true kyphosis that requires at minimum a radiological evaluation with films of the entire spine, in AP and lateral views. If vertebral epiphysitis is most often at the origins of the sagittal vertebral deviations encountered in daily practice, the other causes pose diagnostic and therapeutic problems that are often more complex. They include congenital, paralytic, infectious, cancerous and post-traumatic kyphosis, or kyphosis due to constitutional bone diseases. Surgical treatments, that have only an exceptional place in treatment of the regular kyphosis of the adolescent, are potentially indicated in all of the other situations.

Imaging of traumatic dislocation of the hip in childhood.

BACKGROUND: Traumatic hip dislocation in childhood is a rare consequence of violent trauma. After reduction, outcome is usually favourable although epiphyseal necrosis can occur. Reduction must be carried out as soon as possible and is achieved easily, although if the labrum is involved, surgery may be required to achieve complete reduction. OBJECTIVE: To analyze a retrospective series of traumatic hip dislocations in children, describing the therapeutic and imaging strategy. MATERIALS AND METHODS: A total of 42 patients were studied. Their mean age was 10 years 3 months. All relevant radiographic, CT, MRI and radionuclide bone scan examinations were reviewed. Special attention was paid to associated lesions. RESULTS: In 22 patients the dislocation was caused by low-energy trauma. Road traffic accidents accounted for 17 dislocations. An acetabular fracture was present in six patients and the femoral head was fractured in three. Reduction was easily achieved in 31 patients. In 11 patients the postreduction radiograph and CT showed joint space asymmetry secondary to labral entrapment. Only two patients developed epiphyseal necrosis. CONCLUSIONS: It has been difficult to define and evaluate accurate principles for a medical imaging strategy in this group of patients. Analysis of plain radiographs is essential before and after reduction of the joint, and it is important to perform postreduction CT in every patient whose joint space remains widened. A radionuclide bone scan should be performed between the second and third weeks after injury to assess epiphyseal vascularity. With the use of specific sequences, MRI may be an alternative modality to assess epiphyseal vitality.

Traumatic dislocation of the hip with separation of the capital epiphysis: 5 adolescent patients with 3-9 years of follow-up.

We reviewed 5 cases of type I epiphyseal fracture with dislocation of the femoral head from the acetabulum in adolescent patients. All children had an open reduction and screw fixation. In all cases, the femoral head developed avascular necrosis. The clinical result after a mean of 3-9 years' follow-up was good according to the Merle d'Aubigné-Postel scale. Despite necrosis, 2 heads developed spherically after treatment: one which had a primary physeal resection and fixation, the other after an autogenous bone graft in the screw track following removal of the screw.

Traumatic hip dislocation in childhood.

Traumatic dislocation of the hip in childhood is uncommon and can be a consequence of minor trauma. The authors report a series of 35 dislocations in skeletally immature patients. Most were isolated posterior dislocations without acetabular lesions. In 75% of cases, reduction of the dislocation was easy. Nine children required surgery to remove interposed joint capsule and/or osteochondral fragments to achieve anatomic reduction. Outcomes were generally good, except in one patient in whom a displaced fracture of the femoral physis was followed by total head avascular necrosis. One case of partial necrosis had a satisfactory outcome. Epiphyseal necrosis, though uncommon, appeared to be inconsistent to prevent and hard to predict. Bone scan seems to be more effective than MRI for the detection of necrosis.
