Compressive osseointegration technology, which provides immediate, mechanically compliant endoprosthetic fixation, has been adapted for massive proximal tibial reconstructions in an attempt to avoid aseptic failure encountered with conventional stems.
Compressive osseointegration technology can thus achieve acceptable short-term endoprosthetic fixation results and may reduce the risk of aseptic loosening reported with conventional...

Bone tumours include both benign and malignant lesions. Benign lesions may cause pain, expansion into local structures, joint dysfunction and predispose to pathological fractures. Secondary malignant tumours are much more common than primary malignant bone tumours.

Short descriptions and illustrations of osteosarcoma, Ewings, chondrosarcoma and myeloma. Links to fuller descriptions of these conditions.

From Applied Radiology General Approach to Lytic Bone Lesions Posted 05/21/2004 D. Lee Bennett, MD, MA; Georges Y. El-Khoury, MD Abstract and Introduction Abstract When interpreting musculoskeletal radiographs, a radiologist must be able to identify a lytic lesion and provide a definitive diagnosis or a reasonable differential diagnosis for the lesion....

Bone leiomyoma is a rare neoplasm, and only about 2 dozen cases have been reported in the literature.1–3 In this brief report we describe a case of leiomy- oma arising from the iliac bone in an...

The purpose of this study was to compare the oncologic, reconstructive and functional outcomes of patients who underwent osteoarticular allograft reconstruction with those who underwent arthrodesis for a primary malignant bone tumour of the proximal humerus.
Discussion. In this study, there was a trend towards improved function following arthrodesis compared to...

Pathology Update Pathologic and Radiologic Features of Primary Bone Tumors from Cancer Control: Journal of the Moffitt Cancer Center Douglas Letson, MD, Robert Falcone, PA, and Carlos A. Muro-Cacho, MD Introduction Primary bone tumors are comparatively rare and, therefore, physicians rarely accumulate enough experience in the management of these neoplasias. Due to the complexity in...

Malignant bone tumours are commonest at the age, when growth is greatest, the growth-spurt of puberty. The commonest location is around the knee, a location where the neighbouring bones are increasing their length relatively faster than anywhere else. Clinicians are advised to have a high index of suspicion. The presenting...

PURPOSE: To review and compare the postoperative outcomes of 3 types of shoulder reconstructions: prosthetic arthroplasty, clavicula pro humero reconstruction, and allograft arthrodesis.
CONCLUSION: A stable construct is the treatment goal for shoulder reconstructions, as it enables effective function of the arm and hand.

We present the results in 12 patients of arthrodesis of the knee using a vascularised fibular graft after resection of a malignant bone tumour. At a mean follow-up of 95 months (60 to 178) all patients were free from disease although 11 had had at least one complication, with stress...
