An integral part of plastic surgery, lower extremity reconstruction is centered on treating wounds and defects secondary to trauma, sarcoma (cancer) surgery, deformity, or chronic disease. These “lower extremities” encompass hips to toes.
The overall goal for lower extremity reconstruction plastic surgery is to cover defects and open wounds in the leg, allowing patients to continue their active life with the use of their leg(s), return to work, and avoid amputation.
One potential complication of this reconstructive surgery is lymphedema – or fluid build-up in the soft tissue.
Typical reconstruction cases often result from:
It is critical to address open wounds immediately. An exposed bone that is not covered by soft tissue is at risk for osteomyelitis, bone necrosis, or sepsis. Osteomyelitis is a major cause of limb amputation.
Open wounds on the lower extremities may also cause acute pain, which makes it difficult or impossible to walk or continue daily activities. Exposed tendons in the leg may become dry and die, and exposed blood vessels are at risk of rupture.
Dr. Saber possesses the orthopedic technical skill to repair bones, tendons, muscles, blood vessels, nerves, and skin. Though some patients can be healed after only one surgery, those with more complex cases often need several follow-up surgeries.
The following is a partial list of lower-limb reconstruction surgical procedures performed by Dr. Saber.
Lower extremity flap coverage uses the tissue adjacent to the wound to cover moderate defects in the legs such as exposed bones, blood vessels, and tendons. Unlike a skin graft, a flap is transferred with an intact blood supply and remains connected to its origin.
Skin flaps are used when the injury has lost tissue and is too big for the edges to be brought together correctly. The flap is fed by the same blood supply where it was taken until new blood vessels grow. A flap provides the benefit of supplying tissue of similar appearance and thickness so the cosmetic result is superior to a skin graft.
Vascularized skin flaps typically heal faster than skin grafts. Plus, you don’t have to create a separate wound on another part of the body.
For a skin graft, the doctor takes healthy skin from one part of the patient’s body (donor site) and transplants it to the site of injury. After just a few days, the graft develops blood vessels and connects to the skin around it. Skin grafts are particularly effective when patients suffer from burns, wounds, disease, or infection.
Though most plastic surgeons use healthy skin from a person’s body (autograft), if there is not sufficient healthy skin, the surgeon may use skin from a cadaver (allograft). It should be noted that animal skin grafts are usually temporary until the patient grows new, healthy skin.
Skin for a skin graft often comes from:
Sometimes, there isn’t enough healthy skin on a person’s body to use for the procedure. If this happens, a provider may take the skin from a cadaver (allograft). If a cadaver cannot be readily found, doctors also may use the skin from an animal, such as a pig (xenograft).
In recent years, with an aging population, total knee arthroplasty (knee replacement) has become more prevalent, which makes complications inevitable. Sometimes, a lower extremity injury can leave a prosthetic knee exposed. Physicians have discovered that it is possible to save the knee with lower extremity free tissue transfer, even if an infection has set in.
Case reports confirm that a free flap over the exposed knee prostheses has a high limb salvage rate – often alleviating the need for amputation.
Open fractures are extra worrisome because not only is the bone damaged, the body’s protective skin barrier is broken and the risk of infection is high. Between 3.5 and 6 million fractures occur in the United States each year, with about 3% of those being open fractures. There are different treatment options depending on the status of the soft tissues surrounding the fracture site. The goals of treating an open fracture are to prevent infection, knit the bones, restore function, and cover the wound with soft tissue reconstruction. Important aspects of wound healing are rapid surgical timing, wound closure, a tetanus shot, and wound irrigation.
Dr. Sepideh Saber, MD, FACS, offers a more sensitive, female perspective for patients of all ages, genders, and orientations. Patients from all walks of life have praised not only their final outcomes but her caring, thoughtful approach to all types of appearance and health-related matters.
Dr. Saber graduated from Stanford University’s world-renowned medical school and did her reconstruction and plastic surgery residency at the University of Southern California (USC). She then completed a fellowship at New York University (NYU) in the extremely challenging and delicate area of hand surgery, as well as microsurgery.
