We reviewed 40 cementless Porous Coated Anatomic knee replacements in 34 consecutive patients. The average follow-up was 12.9 months (range 6 to 36 months). At review, loose beads were identified in 23 knees, in 11 on the femoral side and in 16 on the tibial side (in five knees on both sides). One loose bead was adjacent to the patella. In four knees there were intra-articular beads. Radiolucen...

Preliminary results show microradiography and scanning electron microscopy (SEM) to be more accurate methods of accessing growth layer groups (GLGs) in the teeth of Tursiops fmncarus than transmitted light microscopy. Microradiography shoas the rhythmic deposition of mineral as alternating radiopaque and radiolucent layers. I t improves the resolution of CLGs near the pulp cavity in older indiv...

The angiographic features of the left ventricle were examined in patients with idiopathic hypertrophic subaortic stenosis who had clinical and hemodynamic evidence of obstruction. Of 36 combined hemodynamic and angiographic studies considered to be technically satisfactory, 33 showed a characteristic combination of abnormalities. In the frontal projection in systole, a linear radiolucent area e...

Vertical root fractures (VRFs) in teeth without endodontic treatment are relatively uncommon. The diagnosis is based on clinical and radiographic presentations. It might be difficult to detect VRFs in non-endodontically treated molars by conventional radiographs in certain situations because of the limitations of 2D images and many others factors such as the VRFs being in their early stages. Ro...

A retrospective radiographic evaluation of 39 acetabulae reconstructed with Trilock press-fit components (Depuy, Warsaw, IN) without use of supplementary fixation was performed. The following radiographic criteria were evaluated: change in component inclination angle, migration, osteolytic areas, and radiolucent lines. Acetabular components were considered loose when there was migration greater...

introduction: foreign bodies in the upper aerodigestive tract often get lost following inappropriate attempts at removal. children may present late with localized infection, posing a challenge to the otolaryngologists in a referral set-up in diagnosing and retrieving such foreign bodies.   case report: a two-year-old boy presented with refractory purulent rhinorrhea and intermittent low-grade f...

The objective of this study was to investigate the hypothesis that the increased constraint of a medial rotational knee promotes earlier loosening of the prosthesis. All patients with a Freeman-Samuelson 1000 knee arthroplasty (medial pivot design), (group 1), or a Freeman-Samuelson Modular knee arthroplasty, (group 2), with a minimum follow-up of 2 years (mean follow-up 4 years) were identifie...
