The majority of elderly patients with a displaced fracture of the proximal femur are now treated with a hemiarthroplasty. Prosthetic joint infection is a devastating complication, and the infection rate is high in this group of elderly patients. Local application of gentamicin produces high antibiotic concentrations in the wound. The aim of this study is to determine whether locally administered collagen-gentamicin in the joint perioperatively in addition to routine IV prophylaxis with beta-lactam antibiotics can reduce the early postoperative infection rate (< 4 weeks postoperative)after hemiarthroplasty in proximal femoral fractures.

Primary Outcome Measures:
  • Number of patients with postoperatively infection after hemiarthroplasty to evaluate locally administered collagen-gentamicin peroperatively [ Time Frame: Within 4 weeks after prosthetic surgery ] [ Designated as safety issue: No ]
    A randomized multicentre trial

Enrollment: 800
Study Start Date: January 2011
Study Completion Date: August 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Collagen-gentamicin sponges
Two sponges of collagen-gentamicin will be inserted into the hip immediately before closure of the wound. Each sponge (10 by 10 cm) contains 280 mg of collagen and 130 mg of gentamicin.
Device: Collagen-gentamicin sponge
A 10 by 10 cm sponge consisting of 280 mg collagen and 130 mg gentamicin.Two sponges are inserted during hemiarthroplasty surgery, one in the joint and one underneath the fascia at the time of surgical closure.
