Dislocation of talonavicular joint is a very rare injury and frequently misdiagnosed. We had treated an above injury with closed reduction and short leg cast followed by good result in 15 months follow-up.

To our knowledge, rectal cancer arising at the anastomotic site after surgery for Hirschsprung's disease has not been reported. We report a case of mucinous adenocarcinoma arising at the anastomotic site after Soave operation 26 years ago.

Most fractures of the proximal humerus are managed well to simple conservative treatment. But open reduction and interhal fixation of the fragment is definitely indicated in certain types of displaced fractures. Thirty eight cases of fractures of the proximal humerus which were treated at Inje Medical College from January 1980 to December 1985 were analyzed both clinically and radiologically accordingto Neer's classification and the following results were obtained. l. Among the 38 patients, the ratio of male and female was 2.2:1 and the highest incidence was in the fifth decades. 2. The main cause of fracture was traffic accident, 20 cases (52. 6%) and the the next one was falling from a height. 3. According to the classification of Neer, one part acture(52.6%) was the most common type. 4. The common associated injuries were fracture of the lower extremities and forearms. 5. Thirty two cases(84.2%) were treated by conservative treatment and six cases by operative treatment. 6. Thirty eight cases were followed form 6 months to 5 years and 6 months, average 14.3 months, and the results were analyzed according to Neers criteria and 26 cases (68. 6%) showed excellent results. 7. Two cases of limitation of shoulder motion were observed as a complication and one cases of paralysis of deltoid muscle by axillary nerve injury was observed. Excellent functional result could be obtained by a simple external support with early motion in a minimal displacement of proximal humeral fracture. Satisfactory functional result could be obtained by a open reduction and internal fixation with early motion in a severely displaced fracture. But long term immobilization of shoulder could have a poor functional result.

With the expending use of sublaminar segmental instrumentation, various complication, including paraplegia, paresis, dysesthesia and dural tears, have been reported. These findings suggest that the displacement of sublaminar wires toward the spinal eord during extraction followed by spinal cord damage. The cut surface of Luque sublaminar wire is sharp and has a barb and it may cause damage to the spinal cord. The cut end of Luque wire was inserted into the Intracath (a kind of angiocatheter) 16 gauge and pulled parallel to the lamina. And we found the Intracath followed by Lugue wire in the operating field. Lateral view of spine roentgenogram revealed that the radioopaque Intracath was passed under the lamina in 3 mm in depth. When the Luque wire is removed with inserting into the Intracath 16 gauge and pulled parallel to the lamina, the dura can be protected by the cut end of Luque wire.

A precise fit of the implant prosthesis is one of the most important factors in preventing mechanical complications. To analyze the degree of the misfit of implant prosthesis, a modal testing experiment was accomplished. And to interpret the modal testing analysis mathematically, three-dimensional finite element models were established. In the experimental modal testing analysis, with a laser displacement meter, FFT analyzer, impact hammer, etc., natural frequencies of the models with various degree of prosthesis fit were determined after the frequency response function were calculated. In the finite element analysis, the natural frequencies and mode shapes of the models which simulated those of experimental modal testing were computed. The results were as follows : 1. Natural frequencies of the prosthesis-abutment were related to the contact state between components. 2. In the modal testing experiment, the natural frequencies increased from 50micrometer to 200micrometer gap and reached a plateau. 3. In the finite element analysis, the natural frequencies decreased gradually according to the increase of the gap size. 4. In the finite element analysis, the mode shapes of model 1 with misfitting prosthesis showed different patterns from those without misfitting prosthesis. 5. The devices including a laser displacement meter used in this study were useful for measuring the natural frequencies of an implant prosthesis which had various degrees of fit.
