Surgical reinterventions following hip hemiarthroplasty

Indication for failure	Mean time to failure (range)	Surgery performed	Outcome
Periprosthetic fracture (n=9)	0.56 yrs (6 days – 3.0 yrs)	ORIF with plates and cables (n=9)	No further surgery (n=7); re-fracture needing ORIF and long stem THR (n=1); removal of metalwork for pain and impingement (n=1)
Deep infection (n=8)	0.18 yrs (15 days – 0.7 yrs)	Removal of prosthesis, washout and debridement (n=8)	Further washout and debridement (n=5); no further surgery (n=3)
Unexplained pain (n=6)	0.75 yrs (6 days – 1.5 yrs)	THR (n=6)	No further surgery (n=5); dislocation of THR requiring closed reduction (n=1)
Aseptic loosening (n=5)	1.2 yrs (0.5 – 2.2 yrs)	THR (n=5)	No further surgery (n=5)
Dislocation (n=1)	2 days	Open reduction (n=1)	Girdlestone arthroplasty (n=1)

ORIF = open reduction and internal fixation; THR = total hip replacement
