A two year in vivo study of polyvinyl alcohol-hydrogel (PVA-H) artificial meniscus.

For the recognized importance of knee meniscus function, the treatment of meniscus injury has been changing from resection to repair. However, depending on the type of injury, meniscectomy sometimes cannot be avoided. In such a case, it is important to anticipate the future problem of degenerative change or osteoarthrosis in the knee joint.

Significance of peak value and duration of the interfacial shear load in evaluation of the bone-implant interface.

Objective: To determine if there is any merit in measuring peak load duration in studies of bone-implant interface during a pull-out test was performed to record the interfacial shear load.

Design: Mechanical and histological investigations were performed to determine the bone-implant interfacial strength.

Background: A common long-term problem following artificial joint replacement is the formation of an intervening fibrous tissue seam at the interface between bone and a prosthesis.

Case report: intraoperative left common iliac occlusion in a scheduled 360-degree spinal fusion.

Study Design: This is a case report of a left common iliac artery occlusion identified as an intraoperative complication during a planned (combined anterior interbody and posterior fusion) 360 degrees spinal fusion.

Objective: The purpose of this report was to document the occurrence of this rare complication during a planned 360 degrees fusion and to increase the awareness of this potential intraoperative vascular complication.

Summary Of Background Data: Several cases of left iliac artery occlusion after anterior spinal surgery have been reported, but there has been no reported case of intraoperative iliac artery occlusion identified during a planned 360 degrees spinal fusion.
