If you have a rare condition called popliteal pterygium syndrome (a genetic condition that occurs when a gene mutation occurs in the IRF6 gene on chromosome 1), you might have pterygium, which is webbed skin on the back of your leg. Only 1 out of 300,000 people have this mutation. The only way to treat it is to undergo popliteal pterygium surgery. Learn when popliteal pterygium surgery is required and the best practices before and after surgery for optimal recovery in this article. Get a consultation with the best Podiatrists in Brooklyn.
When is Popliteal Pterygium Surgery required?
Popliteal Pterygium surgery is needed to treat popliteal pterygium syndrome (PPS), a rare condition that causes extensive webbed skin to run down the back of your entire leg, usually from the hip to the heel. These thickened skin folds are present on both sides of the body of affected individuals and cause problems in mobility of the lower extremity’s affected joints. The pterygium is a tight, fibrous band of tissues that runs beneath the skin, hindering the knee joint’s contractions.
Besides webbing, you may also experience fusing of the digits of the fingers or toes, malformed toenails, or spina bifida (improper formation of the spinal cord). Patients with this condition may have short stature and vertebral anomalies.
This disease may be inherited from an autosomal dominant genetic mutation in the IRF6 gene on chromosome 1. This gene has a transcription factor that is activated in cells in areas affected by this disorder. However, it can occur without a family history of this disorder. Experts found a link between sporadic popliteal pterygium syndrome and advanced paternal age.
To detect this condition, doctors perform a physical exam where they examine the fibrous band of tissue behind the knee and the knee flexion contracture. To confirm the diagnosis, the doctor will order genetic testing to see the IRF6 mutation linked with the autosomal dominant type of PPS. Imaging tests like X-rays or MRI scans of the knees are used to check the loss of knee extension and plan for surgery, to set the location of essential nerves and blood vessels before preventing injury during surgical resection of the pterygium.
Typically, it is treated with surgery by removing or repairing the pterygium. Two techniques are used in the surgical procedure – cutting (tenotomy) and removal (full resection) of the superficial fibrous band. After operating on the tissue, other neighboring tissues need to be lengthened or grafted to function with the new range of motion of the knee joint. In these cases, the surgeon may graft the sciatic nerve and lengthen local tendons to cover the back of the leg to achieve knee extension. Comprehensive treatment also involves restoring joint orientation, which makes acute correction with soft tissue release with or without cutting the bone, or gradual correction using an external fixator. Whatever approach is used, the goal is to achieve a straight and stable knee.
Best practices
These practices help to prevent patient comorbidities and risk factors that play a significant role in determining the suitability for surgery. Conditions like diabetes, rheumatoid arthritis (RA), and obesity affect wound healing and increase the risk of postoperative complications. A thorough preoperative assessment is crucial to identify factors such as:
- Diabetes (you need to be careful of impaired wound healing).
- RA (you need to be careful with infections and compromised wound healing).
- Obesity (you need to be careful with wound complications and infection).
- If you smoke, it impairs your wound healing and increases the risk of complications.
Besides this, you need strategies before the operation to minimize risks and ensure the best possible outcomes. Some strategies that may help:
- Optimize your glycemic level if you have diabetes.
- Manage RA with disease-modifying antirheumatic drugs and biologics simultaneously.
- Quit smoking.
- Manage your weight if you’re obese.
- Review and adjust your anticoagulation therapy, if needed.
Despite careful planning and execution, complications may occur. The most common ones are:
- Infection: manage them with antibiotics and antiviral medications
- Hematoma: may need drainage
- Nerve injury: treated with observation, physical therapy, and sometimes with surgical intervention
- Wound complications: controlled with wound care or revision surgery.
To lower the risk of complications, surgeons can:
- Use prophylactic antibiotics when needed
- Check for hemostasis
- Use atraumatic surgical techniques
- Monitor closely after the operation to detect early signs of complications
Not only preoperative care, but postoperative care is crucial for optimal recovery, which includes:
- Pain management
- Monitoring signs for complications
- Rehabilitation protocols to restore function and strength
- Follow-up appointments to check healing and remove sutures or staples
Pterygium surgery is used to treat a rare genetic condition called popliteal pterygium syndrome (PPS). This disease causes webbed skin from the hip to your heel. It is a very rare condition; that’s why it is hard to diagnose and treat. But once found, pterygium surgery is the only way to fix this and improve your condition.
