[Chronic osteomyelitis of the ilium after autologous bone harvesting in Albers-Schonberg osteopetrosis. A case report].

We report the treatment of chronic osteomyelitis of the iliac wing after autologous bone harvesting in a 17-year old boy with osteopetrosis. A partial resection of the iliac wing was performed followed by systemic antibiotic treatment. The wound healing was without complications. We consider autologous bone harvesting in patients with osteopetrosis to be a critical procedure due to the higher risk of infection.

Quantitative microscopic studies of the distribution and retention of 239Pu in the ilium of the female CBA mouse.

Three month old female CBA mice were injected with 50 nCi kg-1 body mass of minimally polymeric 239Pu-citrate and killed at 24 hours, 10 days, 1 month and 3 months after injection. The distribution of 239Pu in the ilia of these mice was analysed using neutron-induced autoradiography of bone sections together with computer-based methods of data reduction. Results of these investigations demonstrate that while 239Pu is initially localized on bone surfaces, by 3 months after injection it is fairly uniformly distributed throughout mineral bone and its included marrow.

Critical size defect in the goat's os ilium. A model to evaluate bone grafts and substitutes.

Bone defects and their treatment are a well known problem in orthopaedic surgery. A critical size defect is a suitable model to study bone replacement materials. This study describes a critical size defect in the goal and the evaluation of three bone fillers (particulate autograft, particulate allograft, and a polyethylene oxide/polybutylene terephthalate copolymer) in this defect. The goat allows for implantation of large implants and has a metabolic rate more comparable with that of humans than small animals. The critical size defect, located in the goat's iliac wing, is easily reproducible and allows qualitative and quantitative evaluation of bone grafts and bone graft substitutes. After 3 months of healing, the unfilled defects showed 13.5% bone in the defect, the autografted defects 36.3%, and the allografted 18.5%. The copolymer gave only 1.5% bone in the defect; this is in contrast to previous reports. The described model allows for the evaluation of bone graft substitutes before introduction into clinical practice.

Osteomyelitis of the ilium secondary to external pelvic fixation.

Orthopedic surgeons commonly rely on external pelvic fixation in the treatment of pelvic fractures. Superficial pin tract infections have been reported with the use of this fixation, but we found no deep, chronic infections documented in the literature. We report here the case of a 24-year-old man with chronic bilateral iliac osteomyelitis following external pelvic fixation.

Primary bone tumours of the pelvis in childhood--Ewing's sarcoma of the ilium, pubis and ischium (report of 30 cases). (Part I).

30 children with Ewing's sarcoma, the most common malignant pelvic tumour in childhood, were analysed. The diagnosis of Ewing's sarcoma is relatively easy and can be established in most of the cases on plain radiography. The diagnostic radiographic features of the tumour are discussed. The two most important conditions in differential diagnosis are eosinophilic granuloma and the rare primary bone lymphoma. Osteomyelitis should rarely cause confusion unless the clinico-radiographic findings are not properly evaluated.
