Operations for loose shoulder have been performed on 63 shoulders of 44 cases since 1977 of 10 males (11 shoulders) with an average age of 20.5 and 34 females (52 shoulders) with an average age of 18.4. Collagen in capsules and skin from 3 cases of shoulders reported on produced relatively immature collagen fibers in comparison with those from other cases. This suggests that the biochemical characteristics of collagen in operated-on cases may be similar to those in Ehlers-Danlos syndrome.
