Device Story

Intramedullary cement restrictor (plug) used in total or partial hip arthroplasty; prevents bone cement from migrating distally into diaphysis; facilitates cement pressurization at bone-cement interface. Device consists of UHMWPE body with radiopaque stainless steel wire marker; features 6 discs with oblique cuts and central peg. Available in multiple sizes (S to XXL). Used in OR by orthopedic surgeons during hip replacement procedures. Positioned distal to femoral stem tip. Benefits patient by ensuring proper cement mantle formation and fixation of femoral implant.

Clinical Evidence

No clinical studies were conducted. Substantial equivalence supported by non-clinical bench testing, including design validation for canal fit, range adequacy, and structural integrity (breakage risk). Biocompatibility/pyrogenicity testing performed per USP <85>/<151> and European Pharmacopoeia standards.

Technological Characteristics

Material: UHMWPE (ISO 5834-2) and radiopaque AISI 316LVM stainless steel wire (ISO 5832-1). Form factor: 6-disc plug with oblique cuts and central peg. Sizes: S (8-11mm) to XXL (26-30mm). Sterile, single-use. Mechanical sensing/actuation: Passive physical barrier.

Indications for Use

Indicated for patients undergoing primary or revision total or partial hip arthroplasty requiring intramedullary canal sealing. Conditions include arthritis, rheumatoid polyarthritis, congenital hip dysplasia, avascular necrosis, acute traumatic fracture of femoral head/neck, non-union of femoral neck fracture, or failure of previous hip surgery.

- Risk of breakage of highly stressed parts, Design Validation Report Nr: B2 .
- Shelf Life Characterization of Medacta's Highly Crosslinked UHMWPE, Test Report ●
- . Pyrogenicity
- o Bacterial Endotoxin Test (LAL test) was conducted according to European Pharmacopoeia §2.6.14 (which is equivalent to USP chapter <85>) and pyrogen test according to USP chapter <151> for pyrogenicity determination
- the subject devices are not labeled as non-pyrogenic or pyrogen free o

# Clinical Studies

- No clinical studies were conducted .
# VIII. Conclusion

The information provided with this submission supports that the subject devices are substantially equivalent to the identified predicate devices.

Substantial equivalence has been demonstrated through a comparison of intended use, indications for use, design and technological characteristics, as well as performance evaluations.
