A 66-year-old male sustained a left acetabular fracture after a fall. The patient’s past medical history was significant for a previous left hip fracture and left-sided weakness from 2 left sided strokes requiring the use of a hemiwalker. CT scan revealed a typical geriatric both-column acetabular fracture with mild protrusio. The patient failed two days of conservative treatment, complaining of significant pain and discomfort and surgical intervention was requested. The patient was treated operatively through a novel approach to the posterior column traversing down the gluteus medius pillar and curving posteriorly to the acetabulum to go down the posterior column. This novel corridor is possible only with the use of a flexible implant.The anterior column was treated in a standard retrograde fashion, though a much longer construct was made possible by using a flexible implant. The IlluminOss implants were inserted, filled with liquid monomer, and cured using visible light. On postoperative day 1, the patient was weight-bearing as tolerated using a hemiwalker and released from the hospital the following day.At 2-weeks post op, patient was weight-bearing as tolerated with no displacement noted on radiographic imaging.
