Abstract
Joint mobility was assessed in 25 patients who had undergone surgery for complete rectal prolapse and in 25 age‐and sex‐matched control subjects. A significant increase in extensibility of the fifth finger was found in the patients with rectal prolapse. It was further found that there was a progressive decrease in joint mobility with age in both groups.The pathophysiology of rectal prolapse is complex. Factors considered to be important include rectal intussusception associated with the commonly observed lack of rectal fixation within the sacral hollow, with a deep pouch of douglas and weak pelvic floor musculature. The joint hypermobilily demonstrated in these patients suggests an underlying connective tissue abnormality which perhaps contributes to the lack of rectal fixation within the pelvis and to the rectal wall intussusception.
