Periprosthetic infection after total hip arthroplasty is a devastating complication. A two-stage protocol with the temporary insertion of an antibiotic-laden cement spacer is the gold standard treatment for chronic infections (Clinics (Sao Paulo) 62:99–108,

2009). Some authors, however (Int J Med Sci 6(5):265–73,
2009), report mechanical complication rates with spacers in excess of 50 %.Therefore, the aim of this study is to determine (1) the mechanical complications associated with enclosed articulating partial load-bearing spacers when treating periprosthetic hip infections and (2) possible factors of influence.
