Fixation of distal femoral osteotomies with self-reinforced poly(L/DL)lactide 70:30 and self-reinforced poly(L/DL)lactide 70: 30/bioactive glass composite rods. an experimental study on rabbits.

Two self-reinforced poly(L/DL)lactide 70:30 or self-reinforced poly (L/DL)lactide 70:30/ bioactive glass (SR-P(L/DL)LA/bioactive glass) composite rods (2 mm x 40 mm) were implanted into the dorsal subcutaneous tissue and osteotomies of the distal femur were fixed with these rods (2 mm x 26 mm) in 36 rabbits. The follow-up times varied from 3 to 100 weeks. After the animals were killed, three-point bending and shear tests and molecular weight measurements were performed for subcutaneously placed rods.

Fixation of distal femoral osteotomies with self-reinforced polymer/bioactive glass rods: an experimental study on rabbits.

Two self-reinforced poly(desamino tyrosyl-tyrosine ethyl ester carbonate), poly(DTE carbonate) or self-reinforced poly(DTE carbonate)/bioactive glass rods, (2 mm by 40 mm) were implanted into the dorsal subcutaneous tissue and osteotomies of the distal femur were fixed with these rods (2 mm by 26 mm) in 36 rabbits. The follow-up times varied from three to 100 weeks. After sacrifice, three-point bending and shear tests and molecular weight measurements were performed for subcutaneously placed rods.

Fixation of distal femoral osteotomies with self-reinforced poly(desamino tyrosyl-tyrosine ethyl ester carbonate) rods: an experimental study on rats.

Self-reinforced poly(desamino tyrosyl-tyrosine ethyl ester carbonate) poly(DTE carbonate) rods (diameter, 2 mm; length, 26 mm) were implanted into the dorsal subcutaneous tissue of 16 rats. Osteotomies of the distal femur were fixed with these rods (2 mm by 15 mm) in 64 other rats. The follow-up times varied from 1 week to 1 year.

Magnetic resonance imaging of the normal and injured lateral collateral ligaments of the ankle.

Background And Aims: To study the role of MR Imaging in evaluating both normal and injured lateral collateral ligaments of the ankle.

Materials And Methods: Twenty-four patients with clinically diagnosed inversion injury to the ankle and 20 healthy volunteers underwent Magnetic Resonance Imaging (MRI) of the ankle with special emphasis on the lateral complex ligaments.

Results: The anterior talofibular (ATFL) and posterior talofibular ligaments (PTFL) were identified in 100% of the ankles of normal volunteers in the axial plane.

Holding power of metallic plates in cancellous bone. An experimental study on rabbits with polymethyl methacrylate as supporting material.

The holding power of a metallic device in cancellous bone was tested in sixteen rabbits (n = 16). The device was fixed with the support of polymethyl methacrylate. The fixation firmness was studied radiologically and by measuring the bonding strength.
