Role of magnetic resonance imaging in the radiological management of musculoskeletal tumors.
The treatment of bone tumors has developed from amputation surgery to refined methods of therapy in the last 20 years. Limb-preserving operations in particular require exact documentation of the intra- and extraosseous extent of the tumors. ⋯ For this reason, MRI can be considered of great value in the radiological management of bone tumors. While CT is in most cases inferior to MRI, there are still special cases which require angiography.

Medial approach open reduction for congenital dislocation of the hip using the Ferguson procedure. A review of 31 hips.
Between January 1979 and October 1984, 31 congenitally dislocated hips in 19 patients were treated using open reduction via the medial approach, as described by Ferguson, at the Ankara University Faculty of Medicine. Patient age at operation ranged from 3 to 33 months (mean 12.1 months). ⋯ Avascular necrosis of the femoral head was observed in 9.7% and slight, transient ischaemic radiographic changes of the femoral head in 22.6% of the hips; 25.8% of the hips have already undergone or are due to undergo subsequent surgery due to an insufficient radiographic result. The medial approach was found to be a reliable procedure for infants who have not had extensive previous conservative treatment and who are between 7 and 18 months of age.

Ultrasound diagnosis of pathology of the anterior and posterior cruciate ligaments of the knee joint.
We established a method of diagnosing pathologic conditions of both the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) by using ultrasound. Normal ACL and PCL were delineated as hyperechoic images on the screen in sagittal and transverse sections. ⋯ We examined nine ACL and five PCL injuries by our method. This is a safe and an effective method of determining the rupture of ACL and PCL.

Case ReportsChondrosarcoma of the bones of the hand. Report of two cases.
Implantation of chondrosarcoma in the bones of the hands is an infrequent occurrence. We present two cases in which the fifth metacarpal and the proximal phalanx of the index finger, respectively, were affected in two patients aged 47 and 67 years, who, without previous known lesions, came to consultation on the appearance of pain and progressive local growth of tumour. After histological diagnosis we proceeded to disarticulation at the level of the affected bone. We review the literature on the appearance of this type of tumour in the hand.

Proliferative cell response to loosening of total hip replacements: a cytofluorographic cell cycle analysis.
Monocyte/macrophages and fibroblasts are the major reactive cells in the periprosthetic connective tissue in a loose totally replaced hip. Monocyte/macrophages are bone-marrow-derived, hematogenous cells, whereas mesenchymal fibroblasts replenish by local proliferation. The cell-cycle-phase frequency distribution therefore reflects the local mitotic fibroblast response to the loose total hip replacement (THR) implant. ⋯ The highest DNA values were recorded in an osteoarthritic patient undergoing revision 4 years after the primary uncemented THR, while the lowest values were observed in a rheumatoid arthritis patient with a loose cemented prosthesis 15 years after the primary operation. The results suggest that the local proliferative fibroblast response in general is uniform and does not seem to depend on the type of prosthesis or the use of cement. The responses in aggressive granulomatous-type loosening and the common type of loosening were similar.
