In revision hip arthroplasty, this set is used once the prosthetic head has been removed, to free the femoral stem. A jaw extractor grips the implant taper, then a standard hammer fitted with an adjustable sliding weight performs the extraction.
The manufacturer intends it for stems with a neck carrying a modular head, whatever the model. Designed and made in France by AKED, it is distributed by Medfirst under reference 0081 01 00. It is a CE-marked class I medical device.

Positioning
Once the head has been removed, the extractor jaws are placed around the stem taper.
Locking
The handle is tightened by hand until the taper is clamped between the jaws, which secures the instrument to the implant.
Axis adjustment
The hammer screws onto the extractor clevis, which is oriented in the chosen extraction direction.
Extraction
Blows delivered with the sliding weight gradually free the femoral stem.
The set is delivered non-sterile in an individual labelled plastic sleeve, with the instructions for use inside. As a reusable instrument, it is reprocessed according to the facility's cleaning and sterilization procedures, in line with these instructions.
