Aneurysmal bone cysts are benign primary or secondary lesions that commonly arise in long bones and often before skeletal maturity. Little has been written about aneurysmal bone cysts that abut the physeal plate. The records of 15 patients with juxtaphyseal aneurysmal bone cysts were reviewed. ⋯ One of the children underwent repeat curettage and bone grafting with no additional recurrence. In the other two children with recurrence, the lesion had grown away from the physeal plate while remaining static in size and asymptomatic. Based on this study, juxtaphyseal aneurysmal bone cysts may be treated satisfactorily with intralesional surgery and bone grafting with expectation of normal physeal growth.

Lumbosacral fusion in children and adolescents using the modified sacral bar technique.
Between 1986 and 1995 10 patients who were 9 to 18 years of age underwent posterior spinal fusion and instrumentation to the pelvis for correction of spinal deformity using the modified sacral bar technique at the authors' institution. Etiologies of the spinal deformity included congenital scoliosis, cerebral palsy, myelomeningocele, neurofibromatosis, and postlaminectomy kyphosis. Indications for pelvic instrumentation were progressive scoliosis of the lower lumbar spine, pelvic obliquity greater than 15 degrees, and dysraphic posterior elements. ⋯ Pelvic obliquity was corrected from a mean of 20.5 degrees preoperatively to a mean of 7.6 degrees at final followup. The modified sacral bar technique was selected for fusion to the sacrum because of planned or prior pelvic osteotomies, prior posterior spinal fusion and instrumentation, sacral dysraphism, or local anatomic anomalies. The modified sacral bar technique proved to be an effective technique in these patients.
