Radiologic case study. Transient migratory osteoporosis of the hip and knee.

Transient migratory osteoporosis is a self-limited disorder characterized by gradual onset of pain over several weeks to months and usually accompanied by characteristic findings on plain radiographs, scintigraphy, and MRI. Transient osteoporosis invariably resolves with conservative management, and therefore it is important to distinguish this uncommon syndrome from other disorders such as osteonecrosis, osteomyelitis, or infiltrative neoplasms, which require aggressive management. An accurate diagnosis of transient bone marrow edema syndrome or transient osteoporosis would lead to appropriate conservative management without biopsy, as in the case presented here.

Blount's disease: a retrospective review and recommendations for treatment.

Thirty-two patients treated for Blount's disease were retrospectively reviewed. The results of treatment were assessed by clinical and radiographic parameters and arbitrarily classified good, fair, or poor. Five patients were definitively treated with braces; five extremities were rated good and one poor. Twelve patients were treated with a proximal tibial osteotomy performed before their fifth birthday. Nineteen extremities were rated good, one fair, and three poor. Fifteen patients had their initial surgical procedure after the fifth birthday. Eight extremities were rated good, six fair, and seven poor. Recurrence of the varus deformity secondary to an unsuspected medial bony physeal bar occurred in four patients. Resection of this bony bridge concomitant with a varus correcting osteotomy may be indicated. For severe deformity in older children, several different salvage procedures were used.
