After the success of total hip replacement arthroplasty by John Charnley in 1962, it was well known fact that total hip replacement arthroplasty can be applied to degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis, ankylosing spondylitis, even on the fused hip. However the old dislocated hip gives arise a few problem for its total hip replacement with the follwing causes:, 1. floor of the falad acetabulum is very thin and inadequate to receive a socket. 2. distorted anatomy of the acetabulum and proximal femur. 3. short and atrophic abductor mechanism. Total hip replacement arthroplasty could be successful for the old dislocated hip, if the adequate size of cup ard prosthesis are available and there is adequate length of the hip abductor. Preoperatively we can measure the size of the acetabulum and the distorted femur with roentgenogram. But it is not known how to measure or predict whether or not there is enough length of the abductor muscle mechanism preoperatively. Therefore the question arises how to measure or predict the length of the hip abductor in the old dislocated hip. Although this is a preliminary report, it is our feeling that the more the range of motion the hip has, the better the length of the hip abductor muscle. In our series acetabular socket can be positioned at the original site and the osteomized greater trochanter reduced to the femur easily in the cases more than 190 of total range of motion of the affected hips, The range of motion of the affected hip can be measured preoperatively.

MRI has achieved many technical advances in the spatial resolution, temporal resolution, contrast resolution, signal-to-noise ratio, and postprocessing technique. At one session of examination within a tolerable time, MRI can provide integrated information on coronary artery stenosis, systolic dysfunction, myocardial perfusion, and myocardial viability. Delayed enhancement study after contrast administration is highly reproducible and offers unique vision for myocardial viability in the patients with myocardial infarction. Cardiac MRI is very cost-effective and may be one-stop solution for the evaluation of ischemic heart disease.

An apparatus was designed, based on the principle of Grayson's internal calorimetry, for the determination of the choroidal blood flow with thermistor as a sensing element. Experiments with water; 10%, 20%, 30% and 50% gelatin solution; living and dead rabbit eye and enucleated human eye showed that there was a linear relationship between the thermal conductivities and the currents required to raise the heating thermistor by 1 degree. Thus it was found that the Carslaw's law could be applied in these experiments In rabbit's eyes, thermistors were introduced into the suprachoroidal space after separating the sclera from the underlying choroid. At the same time, one of the vortex veins was cut right after the vein emerge from the sclera, and the amount of blood was absorbed and weighed. The results showed that when the blood flow was in the lower range, the thermal conductivity increased abruptly. When the blood flow increased, the increase in the thermal conductivity was at a more slower rate. In the physiological range of blood flow, however, there was a linear relationship between the blood flow and the changes in the thermal conductivity.

The detailed descriptions about clinical features and management of the different types of peripheral neuropathy are beyond the scope of this article. It may be appropriate here to outline general aspects of clinical features and classification of peripheral neuropathies. The clinical history and the abnormalities revealed by physical examination may either suggest the diagnosis or narrow down the diagnostic possibilities, facilitating subsequent investigation. Nerve conduction studies can provide crucial information and are best performed at initial examination. In general, the first broad determination should be made whether the patient has symmetrical polyneuropathy or focal, or multifocal neuropathies. The range of diagnostic possibilities differs between symmetrical polymeuropathy and mutifocal neuropathy. For those patients with symmetrical polyneuropathy, the clinical pattern (that is, whether it is motor, sensory, or mixed, or whether it has proximal or distal distribution) can provide useful information, as well as the rapidity of onset and previous clinical course in established cases. Managements of peripheral neuropathy and planning of its treatment mostly depend on the confirmative diagnosis of peripheral neuropathy. Thus, the best knowledge and understanding of basic principles of peripheral neuropathies are required for facilitating the diagnosis of peripheral neuropathies.
