Inaccurate femoral tunnel placement has been identified as one of the most frequent errors in failed anterior cruciate ligament reconstructions. Most surgeons evaluate the femoral tunnel position on plain radiographs but in a lot of cases it is difficult to detect the femoral tunnel. The goal of this study was to compare plain digital radiographs and(More)
Due to frequent changes in the anatomical nomenclature of the arteries in the posterior cervical triangle (lateral cervical region), anatomical and surgical papers relating to these topics are sometimes difficult to understand and are hard to compare. These changes, coupled with improper knowledge of the gross anatomy and nomenclature of the arteries in the(More)
BACKGROUND Anatomic graft tunnel placement is reported to be essential in double-bundle posterior cruciate ligament (PCL) reconstruction. A measurement system that correlates anatomy and radiographs is lacking so far. PURPOSE To define the femoral and tibial attachments of the anterolateral (AL) and posteromedial (PM) bundles and to correlate them with(More)
Computer assisted navigation-based surgery is a novel and interesting challenge for todays surgeons. One must however keep in mind, that the indications for these techniques (a) should be carefully considered, (b) used only if morbidity is not increased and (c) when previously problematic or inacurate surgical methods can be improved upon. This study(More)
Treatment principles of osteochondral lesions of the talus usually consist of debridement of the chondral part and methods that attempt to stimulate revascularization of the necrotic bony part of the lesion. The latter is mostly achieved through multiple drilling of the subchondral zone. Dorsomedial talar dome lesions are frequently inaccessible with(More)
The male human body found in an Alpine glacier on September 19, 1991 ("Tyrolean Iceman") has, for the first time in history, given scientists a chance to perform detailed anatomical, histological, and molecular investigations on the organs of a person from the Neolithic Age (5350-5100 B.P.). In the present study, tissue samples aseptically taken from the(More)
Follow-up of 197 patients with scaphoid nonunion treated by Russe I and Russe II bone grafting procedures showed that in longstanding cases with pseudarthrosis and in cases with severe necrosis bony union is often not achieved. The reason for this lack of success is the bad vascularity of the damaged scaphoid. In these cases (25 cases performed over 19(More)
UNLABELLED We conducted a randomized, controlled, crossover study to determine cervical spine motion for six airway management techniques in human cadavers with a posteriorly destabilized third cervical (C-3) vertebra. A destabilized C-3 segment was created in 10 cadavers (6-24 h postmortem). Cervical motion was recorded by continuous lateral fluoroscopy.(More)
AIM To define the value of digital radiography with a clinical flat panel detector system for evaluation of wrist fractures in comparison with state of the art storage phosphor radiography. MATERIAL AND METHODS Hard copy images of 26 fractured wrist specimens were acquired with the same exposure dose on a state of the art storage phosphor radiography(More)
The ulnar nerve is supplied basically by the arteries accompanying it in its various locations: in the axillary section, by a branch of the lateral thoracic artery or directly by the axillary artery; in the upper arm, by branches originating from the collateral ulnar superior artery; in the supracondylar section and in the region of the groove for the ulnar(More)
