[A small distal osseous avulsion of the fibrocartilago palmaris of the middle finger interphalangeal joints. Results of conservative therapy].

Chip avulsions of the palmar plate are divided into four degrees (Hintringer). Conservative treatment is preferred for degree I and II and in some cases in degree III. Only a short immobilization for six or seven days is necessary, then the patient will begin with active movement of the fingers. It is important to avoid hyperextension of the joint. Analysis of results in 69 cases with only conservative treatment showed very good results in 72%, good results in 20.4%, and satisfactory results in 4.5%. The results in one case (Hintringer III) was poor.
