InterSpace®
Hip Spacers / Knee Spacers / Shoulder Spacers
Infection to Correction.
The most widely studied spacer technology in the world, InterSpace® is the first pre-formed spacer with 93.3 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.
The spacer’s textured finish increases its surface area, which allows for greater antibiotic release.
Advantages
-
Proven high release formulation and design yields predictable and consistent local antimicrobial activity compared to other treatment options2-4
-
Maintains joint space and allows limited mobility with partial weight-bearing2,5,6*
-
Stabilizes or tensions the soft tissues and reduces bone loss between stages, potentially facilitating easier re-implantation during a second-stage procedure6-8
-
Shortens operating time2
-
Demonstrates functional success rates equivalent to non-infected revisions9
-
Improves quality of life between procedures6
-
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 24 peer-reviewed papers from 22 different sites.1
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 24 papers for a total of 1,024 spacers at 22 centers.
94.4%
Only 57 patients (5.6%) had persistent infection that required a spacer exchange or resection arthroplasty
93.3%
1,024 patients underwent the second-stage procedure, of the 1,024, only 57 patients (5.6%) had an infection at the mean follow-up of 57.6 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
The InterSpace Tapered Wedge allows surgeons to more conservatively treat patients following a peri-prosthetic joint infection (PJI) of a wedge-style stem and this modern tapered wedge design helps to more conservatively address a narrow femoral cavity. The lower profile lateral shoulder allows for ease of insertion when implanting the stem.
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.2-6*
To complement our existing knee spacer, we now offer an augmented tibial stem (ATS), which comes in multiple size and thickness options to best fit patient anatomy without sacrificing the stem length.
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.2-6*

*Partial weight-bearing must be assessed on an individual basis with relation to the anatomic condition of the local bone, bone quality and clinical conditions of the patient during rehabilitation stages. Care must be taken to minimize the risk of damaging bone tissue and the implant through excessive weight-bearing or forced mobilization.
