BACKGROUND: The modified Dall approach is a modified anterolateral approach with osteotomy of the anterior part of the greater trochanter. OBJECTIVES: We aimed to evaluate the adequacy of the modified Dall approach by measuring leg length discrepancy and evaluating offset discrepancy using postoperative radiographs. METHODS: Of 103 cases of total hip arthroplasty (THA), 22 patients (mean age, 6...

Gait initiation is preceded by initial postural adjustments whose goal is to set up the condition required for the execution of the focal stepping movement. For instance, the step is preceded by a shift of the body's center of mass towards the stance foot unloading the stepping leg. This displacement is produced by exerting forces on the ground (i.e., thrust) while the body is still motionless....

Oxygen tension plays an important role in regulating various cellular functions in both normal physiology and disease states. Therefore, drug testing using conventional in vitro cell models under normoxia often possesses limited prediction capability. A traditional method of setting an oxygen tension in a liquid medium is by saturating it with a gas mixture at the desired level of oxygen, which...

Adhesive organs on the legs of arthropods and vertebrates are strongly direction dependent, making contact only when pulled towards the body but detaching when pushed away from it. Here we show that the two types of attachment pads found in cockroaches (Nauphoeta cinerea), tarsal euplantulae and pretarsal arolium, serve fundamentally different functions. Video recordings of vertical climbing re...

A young man of 23, suffering from severe toothache, had taken 36 grains of exalgin between 2 and 11 p.m. Shortly after 11 he relapsed into unconsciousness. When seen, his temperature was found to be normal, his pulse 79, regular, of fair tension, but all his muscles paretic. With severe pain in his head, convulsions occurred every few minutes, and on tapping the scalp or pricking the arm or leg...

A Cable-Driven Locomotion Interface provides a low inertia haptic interface and is used as a way of enabling the user to walk and interact with virtual surfaces. These surfaces generate Cartesian wrenches which must be optimized for each motorized reel in order to reproduce a haptic sensation in both feet. However, the use of wrench control requires a measure of the cable tensions applied to th...

Graduate external compression is a key factor in the successful treatment of venous leg ulcers, but can be damaging if used inappropriately. A new type of bandage has been designed to minimise the risk of tissue damage by controlling the amount of tension within the bandage during application. This laboratory study suggests that the bandage meets its design criteria, and highlights the importan...

The management of disc protrusion is multidisciplinary. In the midway between conservative treatment and open surgery are minimal invasive procedures. Nucleoplasty is a new treatment of discogenic leg pain using bipolar radiofrequency device for vaporising a small volume of nucleus pulposus. Percutaneous removal of nuclear tissue is thought to lower nuclear pressure, thereby reducing nerve root...
