Leg and Lower Extremity Solutions

The loss of a lower limb has a profound impact on a person’s ability to move through life.  Hanger Clinic’s Lower Extremity Prosthetics Program (LEPP) works to restore mobility by combining an array of state-of-the-art components/ leg prosthetics with our patented ComfortFlex™ Socket System. Under the direction of certified prosthetist Kevin Carroll, MS, CP, FAAOP, a nationwide team of lower limb/extremity clinicians undergo extensive socket design training.

Lower Extremity Prosthetics Program

The fit of the socket (the interface between the residual limb and the prosthesis) is the key to successful use of a prosthetic limb. That’s why ComfortFlex™ Sockets are custom-contoured to fit the bones and muscles of the person’s residual limb to provide more control for an active lifestyle. New materials like urethanes, mineral based liners and improved silicone are much more flexible than the previously used hard plastics allowing people of all ages to wear a comfortable, flexible and lightweight leg prosthetics.

The unique design of the ComfortFlex™ Socket is not just for the young athletic amputee, but older adults as well. A comfortable, anatomically contoured socket is just as important to a 70- or 80-year-old patient as it is to a teenager.  Not only do the contours work with the individual’s anatomy to help with proper transmission of forces through the prosthesis to the ground, but they also can enhance comfort.

After decades of working on above-knee and other lower limb/extremity socket designs, it is clear that most successful designs have come about by simply observing nature. Through direct observation of both deep and surface anatomy, many hours of study in cadaver labs, and computerized gait and balance analysis, our lower extremity and leg prosthetic specialists have learned to ignore preconceived ideas and start from a clean slate using anatomical structures as our guide.

This scientific fitting approach has begun to spill over into other levels of amputation such as hip disarticulation and hemi-pelvectomy.  Using the common sense approach of bone, muscle, tendon, and nerve contours makes great sense for any level of amputation. As a result of these developments, some prosthetic users have become involved in areas of work and play that they previously thought were impossible.

Hanger Clinic’s LEPP has extensive experience working with complex cases including hip-disarticulation and trans-pelvectomy amputations, bi-lateral amputees, and those who face unique challenges with their residual limb. The program offers a broad scope of care that helps individuals set and meet goals and ultimately, restores their lifestyles.

Above-Knee Limb Loss Solutions

An above-knee (AK) leg prosthesis consists of a custom-made socket combined with a supportive frame, knee unit, pylon, and foot. Sometimes a suspension sleeve or harness may also be necessary.

Below-Knee Limb Loss Solutions

​A below-knee (BK) leg prosthesis will typically consist of a custom-made socket, a pylon and a foot. Sometimes a suspension sleeve or harness may also be necessary.

Hip Disarticulation

While all prosthetic users face challenges, those with a hip disarticulation or transpelvic (hemipelvectomy) amputation face perhaps the longest road to becoming a successful lower limb/extremity prosthetic user. Research indicates that people reject HD/TP limbs more than any other prosthesis.

Feet and Ankles Prosthetics

Lower limb/extremity prosthetic users have seen an increase in the amount of technology incorporated into prosthetic feet over the past several years. Currently, there are several types of prosthetic feet available that integrate microprocessors including the élan, Proprio, and BiOM.

Partial Foot Prosthetics

​Partial amputations of the foot include:  toe amputation; mid foot amputation (metatarosphalangeal, transmetatarsal); Lisfranc amputation; and Chopart amputation.
