The CurvaFix® IM Implant
Revolutionary Treatment for Fragility Fractures of the Pelvis (FFP)
With the CurvaFix IM Implant, surgeons are able to offer a minimally invasive surgical treatment option to patients with fragility fractures of the pelvis and acetabulum intended to reduce pain and increase the likelihood of earlier mobility and a faster recovery.
What is a Fragility Fracture of the Pelvis?
With the increase in life expectancy, there has also been an increase in age-related medical conditions such as osteoporosis, a disease that weakens bones and puts people at greater risk of fractures. A fragility fracture is often a symptom of osteoporosis.1 A Fragility Fracture of the Pelvis (FFP) occurs in the pelvic ring and/or acetabulum (hip socket) that is the result of an event that would otherwise be insufficient to fracture normal bone.
Common risk factors for FFP are similar to osteoporosis: women aged 65 and older, and men 75 and older. In women under 65 and men under 75, risk factors that increase the chance of a fragility fractures include: prior pelvic fracture, long-term glucocorticoid therapy, history of falls, family history, low body weight, smoking, and excess alcohol intake.1
Today, most patients receive non-surgical (conservative) care for FFP, including bed rest, pain medication, and mobility assistance.2 Often, patients experience worsening symptoms leading to lengthy hospitalizations,3,8-11,16,17 loss of independent mobility,5,15,16 high nursing home admittance,12-15 and high rate of mortality.3-7,13 Although not every patient who experiences FFP is a candidate for surgery, evidence suggests that more could benefit from surgical treatment than receive it today.
The good news: Care for patients with fragility fractures of the pelvis continues to advance with the CurvaFix IM Implant.
Fragility Fractures Can Occur in Various Parts of the Pelvis
The most common areas for fractures are in one or more of these locations:
- Wing of Ilium
- Superior Pubic Ramus
- Inferior Pubic Ramus
- Pubic Symphysis
- Sacroiliac Joints
What Causes a Fragility Fracture of the Pelvis?
In many cases, fragility fractures of the pelvis occur as a result of a single low energy traumatic event, such as a fall from standing or sitting position. Fragility fractures can also happen in the absence of trauma, and rather the result of progressive microtraumas taking place overtime in very weak bone. Typically, these fractures are referred to as “insufficiency” fractures of the pelvis and often worsen over time.18
A New Solution for Fragility Fractures of the Pelvis
The CurvaFix IM Implant is the only implant available that is designed to follow the natural curvature of the pelvis, enabling strong fracture fixation for weak bones.
Through a minimally invasive surgery (MIS), the CurvaFix IM Implant can achieve strong, stable fracture fixation even in weakened bones—potentially overcoming many of the limitations of today’s conventional implants. To date, the CurvaFix IM Implant has been used to treat hundreds of patients, including many suffering from fragility fractures of the pelvis. The CurvaFix IM Implant is designed to provide:
- Strong, stable fracture fixation by holding the broken bones in place with a large implant that follows the curve of the pelvis.
- Minimally Invasive Surgical (MIS) procedure that may enable shorter surgical time, smaller incision, and less postoperative pain compared to invasive alternatives.
- Faster recovery, which increases the likelihood of early mobility and better outcomes.
