Treatment for unstable intertrochanteric fractures in elderly patients: internal fixation versus cone hemiarthroplasty.

PURPOSE: To evaluate the effectiveness of internal fixation versus cone hemiarthroplasty for the treatment of unstable intertrochanteric fractures in elderly patients. METHODS: The choice of treatment was based on the year of admission: between 2001 and 2003, 42 patients (mean age, 73 years) underwent cone hemiarthroplasty using a cementless press fit through a posterior approach, whereas between 1999 and 2001, 45 patients (mean age, 75 years) underwent internal fixation using a dynamic hip screw through a lateral approach in a supine position. Patients with stable fractures with intact lesser trochanter, immobility before injury, age younger than 60 years, or with associated injuries (such as another fracture) were excluded. Patients were encouraged active rehabilitation in bed. Bony union was determined by clinical and radiological examinations. Patients were followed up at 6-week intervals in the first sixth months and every 3 months thereafter until bony union was achieved. In the final follow-up, 32 cone hemiarthroplasty patients and 38 internal fixation patients were available for evaluation according to Merle d'Aubigne and Postel criteria. RESULTS: There were no significant differences between the 2 groups in terms of sex, age, fracture type, Singh index, follow-up period, hospital stay, operating time, and receipt of blood transfusions. Clinical results of both groups were similar. Hemiarthroplasty patients were allowed full weight bearing significantly earlier than the internal fixation patients. CONCLUSION: Cone hemiarthroplasty can be an alternative treatment for unstable intertrochanteric fractures in elderly patients so as to achieve earlier mobilisation.

Environmental sampling for Cryptococcus neoformans var. gattii from the Blue Mountains National Park, Sydney, Australia.

The environmental association of Cryptococcus neoformans var. gattii with decaying wood in tropical and subtropical regions of the world is well documented. In Australia, the yeast appears confined to certain species of Eucalyptus or very closely related tree species. In this study, we attempted to isolate C. n. var. gattii from different gum tree species in the Blue Mountains National Park. Out of 99 samples from 9 different tree species, only 3 yielded viable yeast colonies; 2 were from turpentine gums (Syncarpia glomulifera) and 1 was from a decayed stump of an unknown species. All of the colonized trees occurred in close proximity in urbanized areas of the Park, and all isolates shared identical DNA fingerprinting profiles. We suggest that domestic animal vectors may be responsible for the introduction and transmission of the yeast in this region, but that propagation and dispersal are very limited. This study indicates that C. n. var. gattii may occur on trees and in areas that were not previously expected to host it. However, the low incidence in the Blue Mountains National Park means this yeast is unlikely to pose any hazards to humans and animals living in or visiting this area.

Intraobserver and interobserver reliability of Kalamchi and Macewen's classification system for evaluation of avascular necrosis of the femoral head in developmental hip dysplasia.

This study evaluates the intraobserver and interobserver reliability of the Kalamchi and MacEwen's classification system of avascular necrosis of the femoral head. Radiographs of 48 developmentally dysplastic hips that had an average follow-up of 40.5 months (range: 36 to 52 months) and that had been treated by the same operative technique were interpreted twice by four experienced pediatric orthopaedic surgeons. When the absence or presence of avascular necrosis was taken into consideration the average intraobserver agreement percentage and kappa coefficient were 86% and 0.71, respectively. The average interobserver agreement percentage and kappa coefficient were 83% and 0.66, respectively. When the agreement on the type of avascular necrosis was analyzed, the average intraobserver agreement percentage and kappa coefficient were 85% and 0.74, respectively. The average interobserver agreement percentage and kappa coefficient were 81% and 0.66, respectively. No statistically significant difference was found between the rates of avascular necrosis of four observers. The Kalamchi and MacEwen's classification system was found to be reliable and reproducible.
