[Data on patients with scaphoid pseudarthroses of the hand].

A group of 63 patients with non-union of the scaphoid diagnosed by chance during 1971 until 1977 was compared with a second group of 112 patients from the period of 1953 to 1970. They were similar in age, the occasion which gave rise to detection and diagnosis, and localisation of the pseudarthrosis. Marked differences were found in the interval between the time of accident and diagnosis and the extent of arthrotic changes.
