ABSTRACT
Of 20 cases of rupture of tendo calcaneus following sports activity, 19 were complete and required surgi-cal repair, tbe other being incomplete, was treated with a cast with the foot in plantar flexion for 6 wk. Recovery was seen in all within half a year. Rupture in the mid-portion constituted 85%. Microangiog-raphy of amputation specimens and cadaveric tendons and histological study of cadaveric tendons showed thatblood supply was poorest in the mid-portion. Electronmicroscopy revealed hyaline degeneration in the tendon,which might account for the rupture. Mo-target X-ray was helpful in the early diagnosis of rupture and tendinitis calcaneus in 88 patients(170 films ). Early sutgical repair is preferred if indicated. Overloading should be avoided to prevent rup-ture. A 500-m. jogging daily helps the sufferers of tendinitis with better circulation. Local application ofsteroids should be administered with caution.
ABSTRACT
Objective To reconstruct three-dimensional (3D) image of heart and coronary artery on internet and explore the reliability. Methods After the contrast medium was injected into coronary artery of 2 heart specimens, hearts were scanned by UFCT with enhancement volume. One patient's UFCT images of coronary artery angiography were also chosen.Then the primitive images were transposed format, removed noise, specified interesting areas. 3D software on server was applied to reconstruct heart and coronary artery. Results The reconstructed 3D images of the heart and coronary artery were realistically displayed, freely rotated and transected.Main parts and branches of coronary artery were similar to those in the images of the UFCT. Conclusion Heart and coronary artery can be reconstructed on internet,which offers a new approach for reconstructing organs and tissues of human being.;
