Twenty patients each with a fractured femoral neck had a prosthesis with a built-in ball-and-socket joint inserted. Movements at the built-in joint were compared with total hip movement immediately after operation, one month later and three months later. It was found that the built-in joint soon lost mobility and at three months was almost completely stiff. Consequently such joints cannot be expected to prevent the acetabular erosion which is liable to follow femoral head replacement for fracture.
The study findings showed that for rectal tumors located up to 15 cm from the anal verge with a maximal diameter of 5 cm, TEO using standard laparoscopic instruments with a 2D view is feasible and provides results comparable with those associated with a 3D view and dedicated instruments. Furthermore, the 2D procedure can be performed with improved ergonomics due to movable monitors and is considerably less expensive.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
