Abstract
|
|
|
The pelvis is a ring structure made up of three bones; the sacrum and two innominate bones which are connected with symphysis publis, and terior and posterior sacro-iliac ligament, sacro-tuberous ligament and sacro-spinous ligament. This ring
structure
become unstable if breakage occurs in more than two points. Recently it is principle that it is mandatory to restore the anatomy of pelvic ring structure and to fix stably by means of internal fixation or external fixation for successful outcome
after
unstable pelvic ring injury.
We treated 40 cases of unstable pelvic ring injury from Jan. 1987 and have used AO external fixator for the treatment of unstable pelvic ring injury from 1989. We compare the results of conventional treament and that of external fixator
application.
@ES The results are as follws;
@EN 1. By Pennal and Tile classification, type B1; 3 cases, type B2; 18 cases. type B3; 8 cases, type C1; 4 cases and type C2; 7 cases.
2. There are no specific differences in final outcome between two groups and we noticed no specific advantages in reduction of unstable pelvic ring injury by using external fixator.
3. External fixator gives good stable fixation to unstable pelvic ring; we cannot find any more displacement of fracture fragment after its application. So it makes possible to early weight bearing and mobilization without specific problems.
4. For type C fracture, it is difficult to obtain the satisfactory reduction by closed means so it is necessary to open reduction and internal fixation for better result.
