Femoroplasty Device that Repairs the Hip Bone


Less invasive surgical alternative to a total hip replacement (THR) that restores the shape and function of the hip joint.

Key Benefits

  • Requires less invasive surgery of the hip, reducing recovery time.
  • Prevents the patient from needing a THR or delays it for at least 10 years.
  • Less expensive than a THR.

Market Summary

The femoral head, the globe-shaped bone that connects to the hip socket, can collapse from a lack of blood supply which eventually leads to bone death (avascular necrosis). A total hip replacement is extremely invasive (requires an 8-in incision), requires multiple days of hospital recovery time, and weeks of physical therapy. Even then, the prevalence of long-term disability is significant. THR only lasts 15-20 years and each replacement doesn’t last as long, meaning younger patients may eventually run out of bone stock to have the replacement put into. THR procedures are expensive. A less invasive option for a total hip replacement is needed for patients who seek an alternative procedure.

Technical Summary

Emory researchers developed a femoroplasty device as a treatment option to a total hip replacement. The femoroplasty device is a three-component product and composed of a double walled cannula, surgical balloon, and surgical cement. The double walled cannula is made of high grade surgical steel and delivers both the surgical balloon and cement. The unique surgical balloon is made of durable polymer which is inflated to create a seal around the femoral head and holds the cement in place. Surgical cement is delivered to the site and is kept from spreading to undesirable areas by the balloon. Once the bone is stabilized the device is retracted and removed from the site. The femoroplasty device will reduce the cost of treatment and patient recovery time.

Developmental Stage

The device is currently under development.
