Cervical spine stenosis in chondrodysplasia punctata.

Chondrodysplasia punctata (CDP) is a rare skeletal dysplasia characterized by stippled epiphyses during infancy. The frequency is probably underdiagnosed because of the large heterogeneity in this group. Many genotypic variations exist.

Case reports: Atlantooccipital and atlantoaxial traumatic dislocation in a child who survived.

A 4-year-old child with multilevel spinal injury including atlantooccipital and atlantoaxial dislocation, and thoracic spinal fractures was managed nonoperatively with no significant sequelae from the cervical injuries, but persistent paraplegia from the associated thoracic spinal fractures. Although treatment guidelines cannot be established with the result of one case, we propose an algorithm for treatment of such a rare and severe situation.

Ultrasound: a helpful technique in the analysis of congenital vertical talus. A case report.

Congenital vertical talus is a rare condition. In newborns, the diagnosis is evident in severe forms, but it can be difficult to confirm in mild ones. Non-ossified tarsal navicular cannot be visualized on standard roentgenograms until it is ossified.

Simple bone cysts of the proximal humerus complicated with growth arrest.

A simple bone cyst of the proximal humeral metaphysis was found to cause growth disturbance with shortening and deformity in four patients. All had one pathological fracture. Three of them were treated with cortisone injections; the fourth patient, who presented an erosion of the physis, was treated with saline solution irrigation.

Local autograft bone in the surgical management of adolescent idiopathic scoliosis.

Study Design: A retrospective study.

Objectives: The study was performed to determine the efficacy of local autograft bone in idiopathic scoliosis surgery on patients who had had spinal fusion with a Cotrel Dubousset device between 1990 and 1995.

Summary Of Background Data: Studies seemed to promote the used of autograft bone (iliac crest, ribs), allograft bone, or bone graft substitutes in adolescent idiopathic surgery.

Long-term outcome in Desbuquois dysplasia: a follow-up in four adult patients.

Desbuquois dysplasia is a rare chondrodysplasia characterized by short stature, joint laxity, and specific radiographic findings. We report the natural history of four patients (three boys and one girl) with Desbuquois dysplasia ages 16-22 years. The mean height in adulthood was 114 cm (-8.
