The clinical, pathological and ultrastructural features of two cases of tibial adamantinoma are described. Both lesions showed identical features with a mixed histological picture exhibiting baseloid, tubular and squamous differentiation and a prominent stromal (mesenchymal) component. By light microscopy there appeared to be an intimate relation between the epithelial and mesenchymal component...

Background: success of orthopedics surgical procedures such as joint replacement therapy, grafts. Aims and objectives human humeri and its surgical importance’s. for of their nutrient foramina were studied. Material and Methods and all measurements were done by using standard anthropometric instruments and techniques. All bones were obtained from the Department of anatomy, Nims medical collage ...

Ossifying fibroma (osteofibrous dysplasia) is a rare fibro-osseous lesion made up of fibrous tissue with woven bone formation. It is most commonly found in the tibia and fibula of children ten years of age or younger. The most important differential diagnosis is monostotic fibrous dysplasia, which is radiologically similar but without woven bone rimmed by active osteoblasts like ossifying fibro...

The healing of a fracture is one of the most remarkable of all the repair processes in the body since it results, not in a scar, but in the actual reconstitution of the injured tissue in something very like its original form. It is not to be expected therefore that the mechanisms controlling such a process will be easily elucidated and indeed they involve problems of cellular homeostasis which ...

Bone metastases of the long bones often lead to pain and pathological fractures. Local treatment consists of radiotherapy or surgery. Treatment strategies are strongly based on the risk of the fracture and expected survival.Diagnostic work-up consists of CT and biopsy for diagnosis of the primary tumour, bone scan or PET-CT for dissemination status, patient history and blood test for evaluation...

We retrospectively reviewed 70 patients with low-grade (Grade I) chondrosarcoma of the appendicular skeleton treated at the Mayo Clinic from 1980 to 2001. Fifty-four patients underwent wide resections and three patients underwent marginal excision for radiographically aggressive lesions. Thirteen patients were treated with intralesional curettage for more indolent lesions. The mean age of the p...

Although syphilitic lesions in bone have become increasingly rare in European communities, syphilis is still a common cause of bone pathology in the South African Bantu. Syphilis entirely accounts for, or complicates, 90 per cent of all bone lesions-apart from fractures-seen in the Baragwanath Hospital. Syphilis is notorious for the diverse ways in which it may present itself, and an attempt is...

Quantitative ultrasound (QUS) has been introduced in recent years for the comprehensive noninvasive and non-ionizing evaluation of bones. This paper presents a review of our research work of the last decade including experimental and computational studies for the ultrasonic assessment of fracture healing and osteoporosis. The axial transmission and the backscattering methods have been applied t...

Osteitis has been transformed in recent times from a lethal or crippling disease to one in which restitution of bone to normal can be expected (Trueta and Morgan 1954). Yet if diagnosis and treatment are delayed the disease, despite antibiotics, may show all its former complications and may run the same unfavourable course as was described by earlier surgeons (Pyrah and Pain 1933). In Africa an...

OBJECTIVES To present a simplified calculation for the measurement of osteotomy wedges used for the correction of angular uniplanar deformities of long bones and to compare the simplified calculation proposed (circumferential calculation) with the classical trigonometric calculations, as well as with the exact calculation performed by computer software AutoCADtm. METHODS The software AutoCADt...
