Menendez et al4, studied 15 patients, none of which had postoperative loosening or migration, but 56% of the patients had a major complication.
- 5/15 patients had infections that required additional surgery, 3 of which needed revision or removal
- 2/15 had dislocation, one was associated with infection and both needed revision
- 1 patient had broken polyethylene liner that required revision
- 1 patient with extensive heterotopic ossification
Infection and Dislocation
CASE 1: Postoperative deep infection. Antibiotic beads placed after prosthetic removal.
CASE 2: Perioperative dislocation.
CASE 3: Impending dislocation, left. Note angle of polyethylene liner (red arrow). On right, same patient after subsequent dislocation and with deep infection evidenced by antibiotic beads.
CASE 4: Perioperative period, CT scout. Note tiny air bubbles at gray arrowhead.
Same patient as above, deep infection. Prosthesis was removed.
CASE 5: This patient had deep infection. Arthrogram was performed to evaluate for fistula formation. There was no fistula.
