INTERNAL-FIXATION OF UNSTABLE PELVIC RING INJURIES

One hundred and seven unstable pelvic fractures were treated operative ly, Reductions were graded by the maximal displacement measured on the 3 standard views of the pelvis, Criteria were: excellent 4 mm or less , good 5 to 10 mm, fair 10 to 20 mm, and poor more than 20 mm, Overall there were 72 excellent, 30 good, 4 fair, and 1 poor reduction, Ninet y-five percent of all reductions were excellent or good, Open reductio n and internal fixation within 21 days were associated with a higher p ercentage of excellent reductions than in reductions performed after 2 1 days (70% versus 55%), These differences were not statistically sign ificant, however, Complications were infrequent using the techniques d escribed.
