Abstract

AIM:

To investigate inpatient length of stay (LOS), complication rates, and readmission rates for sacral fracture patients based on operative approach.

METHODS:

All patients who presented to a large tertiary care center with isolated sacral fractures in an 11-year period were included in a retrospective chart review. Operative approach (open reduction internal fixation vs percutaneous) was noted, as well as age, gender, race, and American Society of Anesthesiologists' score. Complications included infection, nonunion and malunion, deep venous thrombosis, and hardware problems; 90-d readmissions were broken down into infection, surgical revision of the sacral fracture, and medical complications. LOS was collected for the initial admission and readmission visits if applicable. Fisher's exact and non-parametric t-tests (Mann-Whitney U tests) were employed to compare LOS, complications, and readmissions between open and percutaneous approaches.

RESULTS:

Ninety-four patients with isolated sacral fractures were identified: 31 (30.4%) who underwent open reduction and internal fixation (ORIF) vs 63 (67.0%) who underwent percutaneous fixation. There was a significant difference in LOS based on operative approach: 9.1 d for ORIF patients vs 6.1 d for percutaneous patients (P = 0.043), amounting to a difference in cost of $13590. Ten patients in the study developed complications, with no significant difference in complication rates or reasons for complications between the two groups (19.4% for ORIF patients vs 6.3% for percutaneous patients). Eight patients were readmitted, with no significant difference in readmission rates or reasons for readmission between the two groups (9.5% percutaneous vs 6.5% ORIF).

CONCLUSION:

There is a significant difference in LOS based on operative approach for sacral fracture patients. Given similar complications and readmission rates, we recommend a percutaneous approach.
