Abstract
This is a statistical study on digital fracture and amputation observed in 123 employee of Yasugi Hitachi Metalworking Factory from January 1969 to June 1972.
Digital fractures were 95 cases and digital amputations were 28 cases. Both were commonly observed in the twenties, thirties and fourties of ages. An occurrence of the accident was at 1p.m, and 6p.m. most frequently. Causes of many accidets were mechanical press between the iron materials and crushing down with machines. The types of fractures were almost transverse-fractures and demolished fractures.
The greater part of the casses were male and the left side was more involved than the right. It was the left middle finger that was injured most frequently. As to phalanges, distal phalanx was accounted for 75per cent.
Most of the therapy included the unoperated treatment, such as metalic fixation.
As the results of the treatment, disturbances of joint-function were 10 cases, deformations 10 and pseudoarthrosises 2.
Upon investigation for the therapy, it was concluded that in the case of open fracture crushed skin wound should be treated with careful cleansing and debredment.
