Sinus Tarsi Injuries
Traumatic Orthopaedic Injuries - Soft Tissue And Ligament Injuries: Sinus Tarsi Injuries
Sinus tarsi injuries involve damage to the soft tissues and ligaments located in the sinus tarsi, a small cavity on the outer side of the foot between the talus and calcaneus bones. This area is critical for maintaining foot stability and balance. Sinus tarsi injuries can result from trauma or repetitive strain and may lead to pain, swelling, and difficulty with weight-bearing. Proper diagnosis and treatment are essential to alleviate symptoms and restore function.
What Are Sinus Tarsi Injuries?
Sinus tarsi injuries can involve sprains, tears, or inflammation of the ligaments, soft tissues, or joint capsule in the sinus tarsi region. Common conditions affecting this area include:
- Sinus Tarsi Syndrome: Chronic pain and instability caused by trauma, overuse, or repetitive stress.
- Ligament Injuries: Sprains or tears in the interosseous talocalcaneal ligament or other supporting structures.
- Soft Tissue Impingement: Compression or irritation of the soft tissues in the sinus tarsi cavity.
Causes Of Sinus Tarsi Injuries
Sinus tarsi injuries can be caused by:
- Trauma: A sudden twist or inversion injury to the ankle or foot, often during sports or physical activity.
- Repetitive Strain: Overuse injuries from high-impact activities or poor biomechanics.
- Ankle Sprains: Secondary damage to the sinus tarsi following an ankle sprain.
- Joint Disorders: Conditions such as arthritis or instability affecting the subtalar joint.
Symptoms Of Sinus Tarsi Injuries
Symptoms of sinus tarsi injuries may include:
- Pain on the outer side of the foot or ankle, often worsening with activity.
- Swelling and tenderness over the sinus tarsi region.
- Instability or a feeling of the ankle “giving way.”
- Difficulty walking on uneven surfaces.
- Stiffness or reduced range of motion in the ankle or subtalar joint.
If you experience these symptoms, it is important to seek medical advice to ensure accurate diagnosis and appropriate treatment.
Risk Factors For Sinus Tarsi Injuries
Certain factors may increase the likelihood of sustaining a sinus tarsi injury, including:
- Ankle Sprains: Previous ankle injuries can increase susceptibility.
- High-Impact Activities: Sports or activities involving repetitive jumping, running, or twisting motions.
- Poor Footwear: Inadequate support or cushioning during physical activity.
- Flat Feet or High Arches: Abnormal foot biomechanics can place additional strain on the sinus tarsi region.
Treatment Options For Sinus Tarsi Injuries
Treatment for sinus tarsi injuries focuses on relieving pain, reducing inflammation, and restoring stability and function. Options include:
Non-Surgical Treatments
- Rest and Activity Modification: Reducing activities that exacerbate symptoms.
- Ice and Compression: Applying ice packs and using compression wraps to reduce swelling.
- Pain Management: Medications to relieve pain and inflammation.
- Orthotic Devices: Custom insoles or braces to improve foot alignment and reduce strain.
- Physiotherapy: Strengthening and stabilisation exercises to support the ankle and foot.
- Corticosteroid Injections: In some cases, injections may be used to reduce inflammation in the sinus tarsi region.
Surgical Treatments
Surgery is rarely required but may be considered for persistent or severe cases:
- Debridement: Removal of inflamed or damaged tissues in the sinus tarsi cavity.
- Stabilisation Surgery: Repair or reconstruction of ligaments to address instability.
Dr Scott Tulloch will assess your condition and recommend the most appropriate treatment plan based on the severity of the injury, lifestyle factors, and long-term goals.
When Should You Seek Help For A Sinus Tarsi Injury?
You should consider seeking medical advice if:
- Pain or swelling in the outer foot or ankle persists despite rest and home care.
- You experience instability or recurrent “giving way” of the ankle.
- Walking on uneven surfaces becomes increasingly difficult.
- Symptoms worsen or interfere with daily activities.
Early diagnosis and treatment are essential to prevent complications and promote recovery.
