In order to find a solution, one must first understand the problem
Hip Revision
Current Concepts & Solutions
Cemented Fixation
Implant is affixed into the femoral canal using cement to aide in rapid initial fixation.
Highly polished or rough coated finishes
Cemented Stem Extraction
Proximal forces applied to the prosthesis, thereby breaking the cement-implant interface.
Progressive and systematic removal of embedded cement using chisels, osteotomes or ultrasonic cutters.
OPERATIVE TECHNIQUES ESTABLISHED
Uncemented Fixation
Implant is press-fit into the femoral canal and surface engineered to promote boney ingrowth.
Rough surfaced or HA coated finishes
Uncemented Stem Extraction
Clearing as much of the circumferential fixation at the proximal portion of the implanted prosthesis.
Use of flexible osteotomes and cutters to blindly drive down the anterior and posterior profiles of the implant.
OPERATIVE TECHNIQUE NOT ESTABLISHED
Transforming Healthcare
StemX is the first and only complete system for tackling uncemented hip revision
StemX can be used with any surgical approach, the bespoke cutting tools target the distal tip of the implant and break the implant-bone interface with an average bone loss of 1-2mm circumferential to the prosthesis
Surgeons can remove the need for an extensive trochanteric osteotomy, circlage wiring and expensive revision implants. In most cases, a larger primary implant is used following the initial implant extraction
Patient recovery and surgical time significantly reduced
Key Design Attributes
Cutting tools delivered at the implant-bone interface
No need for extensive trochanteric osteotomy
Will remove any well-fixed uncemented hip implant
Non-power driven
Does not require image intensifiers
Leaves cavity in femur to accommodate similar primary implant
Simple to use
Simple to train
StemX targets the outer profile of the hip implant before a single cut is made.
Universal Targeting Device ensures all cuts are delivered at the bone-implant interface
Historically difficult medial and lateral profiles cleared with minimal bone loss.
Universal targeting device ensures all cuts are delivered at the bone-implant interface
Stem removed leaving cavity similar to extracted prosthesis outside diameter.
Significant reduction in surgical time, surgical cost & time to patient discharge
