ステロイド注入が原因と思われる長母指伸筋腱皮下断裂の経験

抄録

There are many reports about ruptures of the extesor pollicis longus tendon, caused by RA, by trauma, by radial bone fracture etc. We experienced a case of steroid induced rupture of the tendon. Case report; a 16-year-old, female. Chief complaint; disorder of the right thumb. She began working for a stocking manufacturing plant in April 1983. In August she complained of right wrist pain. She was diagnosed as having tendonitis, and was infitrated with steroid four times during two months without immobilization. In October, shee noticed a disorder of the right thumb suddenly when she was washing dishes. Immediately she consulted our hospital. There she was diagnosed as having a rupture of E. P. L. tendon. She was treated surgically. Duving surgery, E. P. L. tendon was ruptured completely and the ends were split finely. They were sutured end-to-end, and immobilised in plaster. The plaster was removed eight weeks after the operation. She could return to the same co pany. We consider the causes of rupture to be delayed healing following steroid injection and mechanical stress over this. We have had a new appreciation of an adverse reactionof steroid and the need for immobilization.
