Cadaver imaging proves valuable learning method.

Abstract

In evaluating the project as a whole, students expressed feeling greater worthwhileness through participation in a special project. They enjoyed working as a team with faculty in an imaging environment and reported having fun and learning simultaneously. Also, students felt a sense of accomplishment in contributing to medical students' learning by participating in this service experience. This helped reinforce their role in health care and the need for cooperative relationships in medical education and practice. Based on student and faculty perceptions, this learning method is considered a valuable alternative to traditional means of performance practice and clinical education. The project's success is the result of: Its organization to meet the needs of both the service commitment and a learning environment. The motivational nature of a special voluntary experience alternative. The highly interactive and dynamic nature of the imaging sessions. The realistic feedback for performance with opportunity for analysis and improvement. While it is evident that a cadaver resource must exist to make such a project a viable option for radiography programs, those with such a resource should consider integrating it with the more traditional learning methods. Many program sponsors may have similar resources available in their environments for projects that provide imaging services as well as unique learning laboratories for radiography students. Close interaction with health educators and researchers along with creative investigation may reveal opportunities for special projects.

A contact lens as an artificial cornea for improved visualization during practice surgery on cadaver eyes.

OBJECTIVE: To describe the use of a polymethylmethacrylate contact lens as an artificial cornea to enhance visualization for practice surgery using cadaver eyes. DESIGN: The opaque cornea of a cadaver eye is removed by trephination. Cyanoacrylate glue is used to secure a large-diameter polymethylmethacrylate contact lens to the corneal rim. RESULTS: Excellent visualization for practice surgery is achieved with this technique. The adhesion of the contact lens to the cadaver eye maintains the anterior chamber sufficiently to perform phacoemulsification cataract extraction or pars plana vitrectomy. CONCLUSIONS: This technique improves visualization of the intraocular structures during practice surgery, thereby enhancing the ability of the learning surgeon to perform and practice delicate surgical maneuvers. The procedure is simple, effective, and inexpensive.

Finding an ideal site for intraosseous infusion of the tibia: an anatomical study.

Intraosseous infusion is a technique used for the administration of fluids to a hemodynamically shocked child in whom attempts to access the vascular system have been unsuccessful. Although few complications are seen, injury to the epiphyseal growth plate during the performance of this technique remains a serious problem. This study investigates the relationship between the site of insertion of the intraosseous needle and the epiphyseal growth plate, and the ease of needle insertion into various locations of the tibia in newborn infants. Fourteen newborn infant cadavers (28 tibias in total) were dissected after placement of four needles: 1). through the tibial tuberosity (Site A); 2). 10 mm distal to the tibial tuberosity (Site B); 3). 20 mm distal to the tibial tuberosity (Site C) and; 4). 10 mm proximal to the tibial tuberosity (Site D). Distances from the distal end of the epiphyseal growth plate were measured. A high number of needle placements at Site A were inserted into the epiphyseal growth plate. Most placements at Site B were between 10 and 16 mm from the epiphyseal growth plate on the right side and between 10 and 15 mm on the left side, and all were inserted without difficulty. Although far from the epiphyseal growth plate, most placements at Site C were very difficult to insert because of the thick cortical bone. All placements at Site D entered the epiphysis or the epiphysis and joint space of the knee. An insertion site of at least 10 mm distal to the tibial tuberosity is therefore recommended to avoid epiphyseal growth plate injury and ensure ease of insertion.

A new testing device for measuring gliding resistance and work of flexion in a digit.

In order to move the finger the tendon force must overcome the gliding resistance of the tendon as well as the forces to move the joints, finger inertias, and external load. These sources, combined, make up the work of flexion (WOF) which has been experimentally used to evaluate the finger function. In this study, we have designed a new device, which can measure the forces at the proximal and distal end of the tendon during finger flexion, so that gliding resistance can be isolated from the WOF. Two index fingers from a pair of human cadaver hands were used for testing this device. Preliminary data showed that internal resistance occupied about 10% of WOF with an intact tendon. However, after tendon repair, the gliding resistance increased 31% of WOF for a modified Kessler repair and 50% of WOF for a Becker repair compared to intact tendon. We simulated joint stiffness by injection of saline solution into the proximal interphalangeal joint. This increased the overall WOF but not the gliding resistance. We believe that this testing device provides a useful tool to evaluate finger function after tendon repair in an experimental model.
