PDF - PURPOSE
To evaluate the radiological and clinical outcomes of intrapelvic anterior plate fixations for Day Classification Type II crescent fracture-dislocations of sacroiliac joints.
MATERIALS AND METHODS
Ten patients who had undertaken the surgical treatment for the sacroiliac joint from 2006 to 2012 were enrolled in this study. All cases fell into Type II by Day Classification for sacroiliac joint injuries. For surgical treatments, the plate fixation through the intra-pelvic anterior approach was first performed for all cases and anterior ring fixation was performed in 4 cases with more severely displaced anterior pelvic ring injuries. Then, radiological and clinical evaluation was implemented.
RESULTS
The bone union was observed from all patients whom performed the surgical fixation. In the radiological results, 9 cases with the anatomic and nearly-anatomic reductions were observed. Out of the 10 cases which performed the rotational displacement analysis, there were 3 excellent cases, 6 good cases and 1 fair case. The 10 cases that performed the deformity index and vertical displacement analysis, less variations were observed in the anterior ring fixations after intra-pelvic anterior plate fixation group. According to the clinical results, 4 excellent cases, 3 good cases, and 3 moderate cases were observed.
CONCLUSION
In the Type II crescent fracture-dislocation of sacroiliac joint, the intrapelvic anterior plate fixation achieved satisfactory anatomical reductions, radiological stabilities and clinical results.

- PURPOSE
To assess the affecting factors of results after the operation of Crescent fracture-dislocation in sacro-iliac joint.
MATERIALS AND METHODS
In 19 patients (mean age, 47.4 year-old) of open reduction and internal fixation for Crescent fracture-dislocation, there were seven type I, 9 type II, and 3 type III fractures according to Day's classification. We assessed affecting factors of radiological and functional results, such as patients' ages, surgical approaches, the fixation extent of pelvic ring, and fracture patterns.
RESULTS
Seventeen of 19 cases united at 14.5 weeks in average, and 2 non-unions occurred with the fixation failure of posterior ring. Satisfactory results were 14 and 15 in radiological and functional evaluation, respectively. In complications, three cases of leg length discrepancy were from an imperfect reduction and two fixation failures. Surgical approach did not show any difference of results, but all cases of unsatisfactory reduction occurred from posterior ring fixation through the anterior approach. Fixation of both rings seemed to have satisfactory results, comparing to posterior ring only. Older patients over 60 year-old had more complications and a tendency to show an unsatisfactory result.
CONCLUSION
In operative treatment of Crescent fracture-dislocation of sacro-iliac joint, it is better to fix both anterior and posterior rings. But, caution is needed to prevent complications in old-aged patients. -
