A survey was conducted of the Herodicus Society membership to assess the current status of treating posterior cruciate ligament (PCL) injuries and compared to a similar survey conducted in 1991. The survey addressed indications, graft choice, surgical technique, graft tensioning, and graft fixation. Seventy-eight active surgeons were sent a 34-question survey pertaining to isolated PCL injuries...

The aim of this study is to investigate the behavior of the healthy mandible under maximum molar bite force to demonstrate the problems associated with the current standard of care procedures for mandibular segmental defect reconstruction (ie, use of Ti-6Al-4V hardware and either a single- or double-barrel fibular graft). With current Ti-6Al-4V mandibular reconstruction hardware, there is a sig...

Received: 22 May 2012 Accepted: 10 April 2013 Abstract Background and Aim: Interdental papilla reconstruction especially at the esthetic zone is among the most difficult periodontal treatments. Papilla deficienciesmay occur following some periodontal surgeries and several techniques, mostly surgical and invasive, have been suggested to correct them. The purpose of this study is to evaluate the ...

Prompt controlled reperfusion of a pulmonary allograft in a sequential double lung transplant may correct cellular ischemia prior to exposure to full hydrostatic pressures and minimize organ dysfunction. We reviewed the process of a sequential double lung transplant and describe the technique of controlled antegrade graft reperfusion of the initial implant as performed at our institution.

Several anatomical anterior cruciate ligament (ACL) reconstruction techniques have been proposed to restore normal joint kinematics. However, the relative superiorities of these techniques with one another and traditional single-bundle reconstructions are unclear. Kinematic responses of five previously reported reconstruction techniques (single-bundle reconstruction using a bone-patellar tendon...

Single fiber recordings were made from auditory nerve fibers of the American bullfrog (Rana catesbeiana). As temperature was raised: (1) Best frequencies of fibers from the amphibian papilla (N = 15) increased. Below 600 Hz best frequency changes up to 0.06 oct/degrees C were found; above 600 Hz changes were less than 0.03 oct/degrees C. In the basilar papilla (N = 4) no significant increase of...

Ionic currents are critical for the functioning of the inner ear auditory sensory epithelium. We set out to identify and molecularly clone the genes encoding the channels responsible for several currents in the chick basilar papilla. Here we describe an inward-rectifying K+ channel, cKir2.3, present in both hair cells and support cells in the apical end of the chick basilar papilla. The biophys...
