Unrecognised compartment syndrome in a patient with tourniquet palsy

We report a case in which compartment syndrome and tourniquet paralysis occurred simultaneously. This is a previously unreported combination which presents a diagnostic problem. We recommend that electrophysiological studies and continuous monitoring of compartment pressures should be used to minimise morbidity in high-risk cases.link_to_subscribed_fulltex

Femoral fractures in a Chinese person with Paget's disease of bone

We report the orthopaedic management of a Chinese patient with Paget's disease of bone and with sequential fractures of the affected femur caused by extension of the disease process and stress concentration of the implants.link_to_subscribed_fulltex

Treatment of unstable trochanteric fractures with Dimon-Hughston osteotomy displacement fixation and acrylic cement

For the management of unstable trochanteric fractures, a new method consisting of Dimon-Hughston medial displacement osteotomy, fixation with a sliding screw sleeve-plate device, with augmentation of the posterior and medial upper femoral cortical defect with acrylic cement, was performed in 84 patients. All patients were allowed full weight bearing on the affected extremity within 1 week of operation. Sixty-five patients were available for follow-up more than 12 months after operation. Complication rates were low and 77 per cent of the patients achieved excellent and good functional results.link_to_subscribed_fulltex

Small strain stiffness of natural granitic saprolite in Hong Kong

Nonlinear stress-strain characteristics and shear stiffness-shear strain relationships of sedimentary soils and recompacted sands at small strains have been reported by many researchers. However, research work on the behavior of granitic soils at small strains has not attracted much attention, despite the fact that many countries around the world are underlain by granitic saprolites. In the study reported in this paper, shear stiffness of a natural granitic saprolite from Hong Kong has been investigated in the field, using the self-boring pressuremeter and geophysical techniques such as the suspension P-wave and S-wave logging method, and in the laboratory, using a triaxial apparatus equipped with internal displacement measuring devices. The observed stiffness-strain relationships of the natural granitic saprolite are highly nonlinear at small strains. Shear stiffness decreases significantly as shear strain increases. At very small shear strains (in the order of 0.001\%), the elastic shear moduli deduced from the suspension S-wave logging method are generally consistent with the predictions made using an empirical correlation based on standard penetration test N values and also with the results of triaxial tests incorporating local displacement measurements. For shear strains larger than 0.01\%, reasonable consistency can be found between the normalized shear stiffness-shear strain relationships obtained using the self-boring pressuremeter and from the triaxial apparatus
