technique, and limitations of anterior internal fixation. Lange RH. Hansen ST Jr. Clinical Orthopaedics & Related Research. [JC:dfy] (201):130-7, 1985 Dec. The management of disruption of the pelvic ring is both complex and controversial. Twenty-four injuries associated with symphysis pubis diastasis were reviewed to evaluate a two-hole plate technique of anterior internal fixation as compared to four-hole plate anterior fixation. The two-hole plate technique appears to be quite acceptable for maintaining reduction of the diastasis and therefore can be used to manage most anteroposterior compression injuries (those without complete posterior disruption). Vertical shear injuries, all of which are grossly unstable, can also be managed with anterior two-hole plates. However, this fixation method must be supplemented with some form of posterior stabilization to maintain pelvic ring reduction.
