Acute traumatic lumbosacral dislocation treated by open reduction internal fixation and fusion.

STUDY DESIGN

Case report of a patient with acute traumatic lumbosacral dislocation.

OBJECTIVE

To report a case of traumatic lumbosacral dislocation treated with open reduction internal fixation and fusion.

SUMMARY OF BACKGROUND DATA

To our knowledge, there are only 49 cases reported in the literature of this exceptional lesion. Complete lumbosacral dislocation is a three-column lesion, and therefore, open reduction internal fixation and fusion is recommended.

METHOD

We report the case of a 42-year-old man who had a vehicle accident. In addition to other fractures, he suffered an anterior lumbosacral dislocation. The displacement of L5 on S1 was 35%. The patient was surgically treated with open posterior reduction fixation and fusion with good result.

RESULTS

Complete fusion was achieved, and at 5 years follow-up, the patient was asymptomatic, and no further slippage has been observed.

CONCLUSIONS

A rare case of acute anterior lumbosacral dislocation treated surgically is reported. We consider the surgical treatment for reduction, decompression, stabilization, and fusion as the method of choice in acute cases of this exceptional condition.
