Arthroscopy of the wrist and finger joints.

Ninety arthroscopies of the wrist and finger joints in 34 clinical cases and two amputated arms were carried out with the number 24 arthroscope. Eighty-four wrist and finger joints of four cadavers and two amputated arms were also dissected for macroscopic observation. Most portions of the interior structures of the wrist and finger joints can be observed by the dorsal approaches. Color photography and punch biopsy are also possible. Some arthroscopic photographs taken with the number 24 arthroscope are illustrated. From these experiences it is concluded that the number 24 arthroscope is a useful diagnostic tool in arthroscopy of the small joints, even though there are still many problems.
