Are you feeling pain at the back of your ankle, especially when pointing your toes? It might be Posterior Impingement Syndrome (PIS), a condition we often treat here at Spectrum Healthcare. Don't let ankle pain hold you back. Find out how to manage and prevent PIS before it worsens!

What is Posterior Ankle Impingement Syndrome?

Posterior Ankle Impingement Syndrome (PIS), often called posterior ankle impingement, happens when tissues at the back of your ankle become compressed. This compression can involve soft tissues like ligaments or tendons, or bony structures. It is often triggered by activities that involve pointing your toes downwards (plantarflexion). While sometimes caused by injury, PIS can also develop from repetitive movements. We're here to help you understand PIS and how our team at Spectrum Healthcare can offer effective solutions.

How Does Posterior Impingement Develop?

• Ankle Sprains & Trauma: A common cause we see at Spectrum is a poorly managed ankle sprain. Inadequate healing can lead to swelling, scar tissue, and instability, increasing the risk of impingement. Proper rehabilitation of ankle sprains is crucial to prevent PIS.
• Repetitive Plantarflexion: Activities like ballet, soccer, gymnastics, and even swimming can repeatedly stress the back of the ankle, causing inflammation and compression.
• Anatomical Factors: Some individuals have an extra bone called an Os Trigonum near the talus. This bone can get pinched during ankle movements, contributing to PIS. Heel spurs can also play a role.

Posterior Ankle Impingement Symptoms

Recognising the symptoms is the first step to getting the proper care. PIS typically presents with:

• Posterior Ankle Pain: Sharp or dull pain at the back of the ankle, often made worse by plantarflexion (pointing toes down) or activities like running, jumping, and dancing.
• Swelling: Mild to moderate swelling and tenderness around the back of the ankle joint.
• Stiffness: Reduced range of motion, particularly in plantarflexion.
• Tenderness: Pain upon palpation (pressing) at the back of the ankle, especially near the Achilles tendon.
• Activity-Related Pain: Symptoms worsen during or after activities that involve repetitive ankle movements.

Diagnosis & Imaging for Posterior Ankle Impingement

Accurate diagnosis is crucial. At Spectrum Healthcare, we rely on a blend of clinical assessment and advanced imaging to identify the cause of your PIS.

• X-rays: Excellent for visualising bony structures, identifying Os Trigonum, heel spurs, or other bone abnormalities that might contribute to the impingement.
• Dynamic Ultrasound: A powerful tool to assess soft tissues and identify swelling. The advantage of dynamic ultrasound is that it allows us to visualise the ankle in motion, observing compression during plantarflexion in real-time.
• MRI: While MRI is the gold standard for soft tissue imaging, ultrasound provides unique benefits in assessing movement.

How Spectrum Healthcare Can Help Your Ankle Pain

At Spectrum Healthcare, we provide a comprehensive approach to treating posterior ankle impingement. Our collaborative team of sports chiropractors and physiotherapists uses advanced technology and evidence-based techniques to help you recover and return to your usual activities.

• Pain Management
  We utilise modalities like Game Ready contrast therapy to reduce inflammation and alleviate pain.
• Soft Tissue Therapy
  Myofascial release, active release therapy, sports massage, dynamic cupping, and dry needling can break down scar tissue, improve muscle flexibility, and reduce inflammation.
• Biomechanical Assessment & Orthotics
  We evaluate your foot and lower limb alignment to identify and correct any imbalances contributing to your PIS. Custom orthotics may be prescribed to support your arch and stabilise the foot and ankle.
• Gait Training
  Our Alter-G anti-gravity treadmill helps you gradually return to weight-bearing activities and running, minimising stress on your ankle.
• Joint Mobilisation
  Gentle mobilisations restore proper joint mechanics and reduce stiffness in the foot and ankle.
• Range of Motion Exercises
  We guide you through a progressive exercise program to restore complete ankle flexibility.
• Strengthening Exercises
  Targeted exercises strengthen the muscles surrounding the ankle, providing support and stability.
• Proprioceptive Training
  Balance exercises (using wobble boards, etc.) enhance stability and prevent future sprains.
• Functional Rehabilitation
  Sport-specific exercises help athletes safely return to their desired activities.
