Twenty-six patients with femoral neck fractures were treated by open reduction, cancellous screw fixation and free fibular grafting. The patients were between 14 and 50 years of age. There were 16 old and 10 fresh fractures. Four patients had radiological signs of avascular necrosis before the treatment was instituted. Bony union was achieved in all… (More)
The standard treatment for an appendiceal mass is conservative therapy followed by appendectomy after 6 to 10 weeks. With the advent of antibiotics designed to prevent the growth of anaerobes, early appendectomy can now be carried out without complication. The authors studied 56 patients with appendiceal mass formation, 26 (group A) treated conventionally… (More)
Four cases of acquired urethral diverticula in male subjects are reviewed. All patients presented with complications such as urinary tract infection, urethral fistulas and stone or sequestrum formation in the diverticulum. The recommended treatment is excision of the diverticulum and repair of the urethra. The relevant literature has been reviewed.
A 25-yr-old female presented with a slowly progressive swelling, occurring over an 8-yr period, in the right lower leg. The swelling was tender and fixed to the underlying bone. Clinical and radiological diagnosis was giant cell tumor (GCT) of the bone. Aspiration cytology smears were cellular showing an admixture of chondroid, stellate, and fibrocytic… (More)
A prospective study was carried out to evaluate the role of ultrasound in early detection of infections of bone. Presence of a hypoechoic collection adjacent to bone was considered highly suggestive of osteomyelitis whereas a hypoechoic collection away from the bone implied a soft tissue abscess. Cellulitis presented as increased subcutaneous thickness. Of… (More)
A lipoblastoma, an uncommon tumor of childhood that can be mistaken for a liposarcoma, was preoperatively diagnosed by fine needle aspiration cytology. The characteristic features on the cytologic smears were the presence of immature fat cells in the form of spindle-shaped cells, stellate cells and vacuolated lipoblasts along with lipocytes. The cytologic… (More)
A 2D Finite Element Model (F.E.M.) of chip formation process, set up with an Arbitrary Lagrangian Eulerian (A.L.E.) formulation, proposed in the software Abaqus/Explicit TM v6.3, is shown. The experimental validation showed a good qualitative agreement. Thus, FEM of cutting process can be considered as a promising and reliable tool for machining development… (More)
BACKGROUND Unicompartmental knee arthroplasty (UKA) has specific indications, producing excellent results. It, however, has a limited lifespan and needs eventual conversion to total knee arthroplasty (TKA). It is, therefore, a temporizing procedure in select active young patients with advanced unicompartmental osteoarthritis (UCOA). Being a less morbid… (More)
Osteomedullography was performed in 17 diaphyseal fractures of the tibia at ten to 12 weeks from injury to assess the reliability and sensitivity of the procedure in predicting non-union. It was found to be accurate in more than 80% of cases in predicting the ultimate outcome early in the course of fracture healing.
