Smaller osteschondral fragments containing little or no cortex present difficult treatment dilemma. Metallic screws or Kirschner wires often require subsequent removal either as part of the original operative plan or because of problems such as loosening and/or cartilage erosion. An attractive alternative would be a biodegradable implant that would transfix an osteochondral fragment with minimal violation of the articular surface. The objectives of this study are (1) to compare osteochondral fracture fixation of 2mm polyglycolic acid (PGA) absorbable pins (Acufex, Manfield, Mass) with that of Kirschner wires (K-wires) in cadavers, (2) to review patient data where osteochondral fractures were fixed with PGA-pins. The following conclusions were obtained: (1) Cadaver Studies: The biomechanical parameters of the osteochondral fractures fixed with absorbable PGA pins were not statistically different from those fixed with K-wires. Based on these laboratory studies it appears that fixation of osteochondral fractures with bioabsorbable PGA pins may offer a viable alternative to the use of K-wires. (2) Clinical Cases: A short follow up period with four clinical cases indicated that in carefully selected injuries, fixation with absorbable pins could become the treatment of choice of smaller joints. For severely comminuted fractures about major joints, PGA absorbable pins may be an adjunct to metal fixation.

The major main aims of the study were to: 1. develop a device to obtain a better result compared to manual puncture site compression; 2. develop a stable device which would not slip during application; 3. help all dialysis patients, especially those patients who are unable to hold their needle puncture sites; 4. relieve the nurse to attend to other activities; and 5. to better utilize the whole length of the graft thereby preventing recirculation of non-dialysis blood and repeatedly puncturing a short length of the graft. A device was fabricated from a light weight plastic material with a C shape. This contour allowed conformity to the various shapes of the dialysis access limbs. The device included a rotatable threaded shaft, with which it was possible to achieve a controlled pressure on the fistula or graft. An internal (shaft) safety mechanism was incorporated so that undue pressure could not be applied on the vascular graft. The device was designed to be stable and comfortable. The puncture site contact surface of the device was designed to be disposable and to minimize any possibilities of cross contamination. Different sizes of clamps were made to best accommodate the various sizes of upper and lower access limbs. An initial clinical study on 25 patients conducted by the dialysis nurses at the University of Alabama at Birmingham and Sylacauga dialysis center, Sylacaga, Alabama demonstrated no problems with the C clamp system.

Intracranial pressure (ICP) monitoring of cerebrospinal fluid (CSF) dynamics is used in the management of neurological conditions associated with intracranial hypertension. An extension of this is the measurement of the system pressure-volume index (PVI) which is intended to provide an indication of the intracranial buffering capacity, used in predicting the change in ICP when the craniospinal system is subject to further volume increments. Alternative means of identifying the intracranial buffering capacity involve the determination of the system compliance (C) or the volume-pressure response (VPR). Here, the authors contrast these measurements in the case of controlled intracranial mass expansion and, further, relate the determination of brain tissue response derived from these measurements to a more direct method of measuring brain tissue properties.

Twelve matched pairs of fresh frozen human cadaveric femurs were tested in axial and torsional loading followed by implantation of an intramedullary nail or a 95/spl deg/ angled plate. An equal number of screws were used above the fracture, in either a grouped or dispersed configuration. Each femur was then tested with progressively more severe simulated fracture patterns. The plate with the dispersed screw configuration had the greatest torsional stiffness (p<0.0001). No significant difference was found in axial or torsional stiffness for nail or plate groups when analysing by increasing fracture severity.

Many people suffer from temporomadibular joint (TMJ) pain and need treatment. However, the outcome of such physical therapy is often not evaluated objectively. The range of motion of the jaw could be used as an objective criterion for monitoring the effect of therapy for such patients. In this study the authors designed and manufactured such a device to measure the three dimensional motion of the jaw for human patients.

For pt. I see ibid., p. 158-61 (1995). Falls rank with automobile and firearms as the leading generators of unintentional injury with direct morbidity and mortality costs. Falls are the leading cause of accident-caused mortality in senior citizens. Slips account for a plurality, if not a majority of falls. Heel slips, from which recovery can be difficult, account for the majority of slip-induced falls. To prevent slips, a comprehensive model for the prediction of slip mould be useful. A comprehensive slip-prediction model must consider both qualitative and quantitative factors. Friction alone may not completely predict pedestrian slip propensity or probability. Here, the authors apply ratiometric analysis of the friction parameters explored in pt. I to characterize the friction-related component of a comprehensive slip-prediction model. Subsequent investigation will require experiments to numerically characterize the factors discussed here.

A thermoluminescence (TL) technique, which is simple but fast and sensitive, was used as a diagnostic tool to test short-term or initial (immediately following sterilization) oxidation of UHMWPE. More than 50% radical species decayed or oxidized in the first 10 min in an oxygen environment and in 25 min in a nitrogen environment. The glow-peak temperatures 130/spl deg/C and 160/spl deg/C of the TL glow curve were also found to be associated with the sterilization conditions, nitrogen and oxygen, respectively.

The performances of textile composite vascular grafts, specially designed and constructed in this work were investigated. In developing compliant structures, textile threads of two widely different deformative characteristics, one matching nearly those of the elastin and other of the collagen fibres, were selected. The materials used were a polyurethane monofilament yarn with low modulus of elasticity and a bulked polyester multifilament yarn with high modulus of elasticity. Tubular grafts of diameter in the range 4-6 mm were made by a weaving process utilizing a foil ribbon loom. Two types of woven grafts were developed. In the first type (HVGI1), polyester threads of 9 tex linear density were used as warp, and the same polyester and pre-stretched polyurethane (7.8 tex linear density) were used as the weft. In the second variant (HVG-2), pre-stretched polyurethane thread combined with polyester were used as both the warp and the weft threads. The grafts obtained were stretchable and thus compliant in both the transverse and the longitudinal directions. The hydraulic permeability was assessed at fixed pressure of 120 mmHg. The surface and pore characteristics of grafts were examined using a scanning electron microscope. Eight HVG-I hybrid grafts were also implanted in the carotid and femoral regions of mongrel dogs for periods of up to one year. The form of the pulse wave found in the graft, the healing characteristics of the surface and the changes in the mechanical properties as a result of implantation were examined.

Over 60 million Americans suffer from "ringing-in-the-ears" or tinnitus. This disorder ranges from mildly annoying to debilitating, and at the moment there is no known effective medical treatment. Acoustic masking of the subjective tinnitus sound does provide a measure a relief for many patients. A narrow band masking device that is tunable and potentially portable is described in this report.

The treatment of mandibular angle fractures is plagued with the highest postsurgical complication rate of all mandibular fractures. Multiple plating systems are available. In this study four plating variations were compared in a biomechanical in vitro study. All plating systems were noncompressive Synthes titanium plates. The 3.0 mm reconstruction plate with 6 holes, the 2 mm universal fracture plate with 6 and 8 holes and tension bands and the 6 hole universal fracture plate without tension band were compared. Measurements of gaps at the osteotomy sites showed no significant difference for the plating systems. However the vertical (inferior/superior) displacements were significantly higher for the six-hole plate without tension. The horizontal (bucca/lingual) displacement for the six-hole plate without tension had also highest displacement value. The addition of a tension band was effective to reduce these displacement values. Quantitative computed tomography scans were used to demonstrate a minimal difference in bone quality.
