It was difficult for a baseball player to recover completely from a frontal dislocated shoulder or subluxation even though an operation was performed because it limits the range of motion of the shoulder. However, recently many baseball players wish for complete recovery. Our team has been making efforts to meet their wishes. This is a report of some cases we have treated. We define a complete recovery as a state when a player can throw a ball fast enough to play on a team without experiencing pain.

We experienced eight fractures of the coracoid process during the period from 1984 to 1992. Seven cases of them were basal fractures and one case was apical one. Two cases were isolated, being in the other six cases combined with acromioclavicular dislocation or clavicular fracture. One patient with minimally displaced fracture of the coracoid process was treated conservatively. But the others were treated by internal fixation with a cannulated malleolar screw, one of which was inserted percutaneously. Postoperatively, Kenny-Howard type harness was worn in each case for four weeks. The result was satisfactory and all surgical cases were united. Neither infection nor loss of function was observed. These fracutures were assessed regarding the cause of injury, region of contusion, and complicated osseous-articular injuries around the shoulder. From the mechanism of injury, they were classified into two major groups: Group I; direct fracture, group II; indirect fracture. The direct fractures were subdivided into two types: Type I; by force from outside, type II; by force from inside. The indirect fractures were further divided into two types; Type I; by ligamentous traction, type II; by muscular traction. It is recommended to treat operatively if a gap of indirect fracture is five millimeter or more on roentgenograms.

心身機能の低下した高齢ドライバーにとって、道路案内標識は、認知や判断の正確性、迅速性を最も厳しく求められる標識である。本研究では、まずはじめに実物の標識を用いて行われた既往研究との比較により、CGによる実験結果との対応関係を明らかにするとともに、CGの長所である複雑な交通場面における標識の判読性について考察し、高齢ドライバーが複雑な判断を伴う状況において、非高齢ドライバーよりも多くの時間を要することを明らかにした。
