Direct stem engagement
PeriNail merges coaxially with the existing femoral stem — a direct, load-sharing connection rather than indirect cables or plates.
Orthopedic Innovation · Patent Protected
Treating periprosthetic hip fractures — without removing the implant.
PeriNext has developed and patented a minimally invasive nailing system that stabilizes femoral fractures around an existing hip replacement — engaging directly with the implant already in place, instead of taking it out.

Why PeriNext exists
A fracture around the implant shouldn't mean removing it.
Periprosthetic femoral fractures — fracture occurring around an existing hip implant — are one of orthopedic surgery's most demanding challenges. They strike a population that can least afford a long, high-risk operation: elderly, frail, often osteoporotic patients. Yet the standard answer has long been major revision surgery — removing a working implant, reaming the bone canal, and inserting a new, longer stem. Alternatively, a long plate is inserted to lock the bone into anatomical plane.
PeriNext set out to change that equation. Our patented periprosthetic nailing system stabilizes the fracture by engaging directly with the implant that is already there — through a closed, minimally invasive technique that leaves the existing stem, the surrounding bone and the patient's recovery window intact. We have completed four first-in-human cases in Israel.
The technology
One nail. Engaged with the existing implant.
PeriNail is inserted through a closed intramedullary technique and merges coaxially with the femoral stem already in place — turning two separate components into one stable construct, without ever taking the original implant out.
Bone & implant preserved
No stem removal, no canal reaming, no periosteal stripping. The existing implant stays in place and the patient keeps their bone stock intact.
Closed, minimally invasive
Inserted through a closed intramedullary approach — the fracture haematoma stays intact, soft tissue damage is minimized, and healing starts sooner.
Built for early mobilisation
A stable construct that supports earlier weight-bearing — critical for frail, elderly patients whose recovery window is measured in days, not months.

Clinical evidence
Biomechanically sound. Clinically gentler.
Compared with long-stem revision or a periprosthetic long plating system — today's default for complex periprosthetic fractures — PeriNext's closed technique is designed to spare exactly what frail patients can least afford to lose: blood, time on the table, and recovery momentum.

Less blood loss
~100–200 mL with PeriNext's closed technique, vs. ~700–1,200 mL for long-stem revision — where transfusion is needed in 6 of 10 cases.

Faster operation
~60–75 minutes on the table with PeriNext, vs. ~152–180 minutes for stem removal, canal preparation and revision implant insertion.

Estimated 1-year survival
A minimally invasive approach means less operative stress on frail patients — where every additional hour on the table carries real risk.
Estimates derived from peer-reviewed literature and PeriNext's closed intramedullary technique; a prospective clinical series is in progress to confirm outcomes head-to-head.
An aging population, a growing need
Periprosthetic fractures are becoming more common — not less.
As hip replacement rates climb and populations age, the number of fractures occurring around existing implants keeps rising. Today these patients are too often offered the same answer regardless of how frail they are: a long, high-risk revision. PeriNext was built for the patients that answer fails most — and for the surgeons looking for a better one.
