Infection to Correction.

The most widely studied spacer technology in the world, InterSpace® is the first pre-formed spacer with 93.8 percent eradication rate.1 Its positive clinical results coupled with the systematic research of surgeon-made devices led to the design of products that could be both mechanically safe and pharmacologically effective.

InterSpace Knee, Hip and Shoulder are preformed, articulating, partial load-bearing structures comprised of gentamicin-impregnated PMMA bone cement. InterSpace is indicated for skeletally-mature patients undergoing the first stage of a two-stage revision arthroplasty.

Features and Benefits

  • Proven high release formulation and design yields predictable and consistent local antimicrobial activity compared to other treatment options.1-3
  • Maintains joint space and allows limited mobility with partial weight bearing1*
  • Stabilizes or tensions the soft tissues and reduces bone loss between stages, potentially facilitating easier re-implantation during a second-stage procedure4-7
  • InterSpace demonstrates functional success rates equivalent to non-infected revisions8
  • Shortens operating time1,4
  • Stainless steel reinforcing core in Hip and Shoulder Spacers
  • Multiple sizing options

Clinical Data

InterSpace® shows its reliability, efficiency and effectiveness when treating joint sepsis with global compilation of clinical evidence from more than 19 peer-reviewed papers from 18 different sites.9

Study Criteria and Outcomes

The inclusion criteria removed case reports, clinical series with less than 10 patients, duplicate studies and series with a mean follow-up of less than 24 months. The exclusion criteria left 19 papers for a total of 732 spacers at 18 centers.

Infection Control at Spacer Removal94.1%
94.1%

Only 43 patients (5.9%) had persistent infection that required a spacer exchange or resection arthroplasty

Eradication Rate at Latest Follow-up93.8%
93.8%

Seven hundred and nine (709) patients underwent the second-stage procedure, of the 709, only 44 patients (6.2%) had an infection at the mean follow-up of 55 months.

InterSpace® Hip

InterSpace Hip is designed to temporarily replace a Total Hip Arthroplasty (THA) that has been explanted due to infection.

InterSpace® Tapered Wedge

As the newest addition to the Exactech Spacer family, the InterSpace Tapered Wedge allows surgeons to more conservatively treat patients following a peri-prosthetic joint infection (PJI) of a wedge-style stem.

This modern tapered wedge design helps to more conservatively address a narrow femoral cavity, and the low profile lateral shoulder allows for ease of insertion when implanting the stem.

Exactech InterSpace Hip is designed to temporarily replace a Total Hip Arthroplasty (THA) that has been explanted due to infection.
Exactech InterSpace Knee is designed to temporarily replace an infected implant during a Total Knee Arthroplasty (TKA)

InterSpace® Knee

InterSpace Knee is designed to temporarily replace an infected implant during a Total Knee Arthroplasty (TKA) and provide the patient with mobility and predictable, consistent local antibiotic release.1,3

InterSpace® Shoulder

InterSpace Shoulder is designed to temporarily replace an infected implant during a Total Shoulder Arthroplasty (TSA) and provide the patient with mobility and predictable, consistent local antibiotic release.1,3
