Calcaneonavicular Coalition: Symptoms and Treatment
The human foot is a complex structure comprising bones, muscles, ligaments, and tendons, each playing a crucial role in maintaining balance and facilitating movement. Within this intricate network, certain abnormalities can arise, leading to conditions such as calcaneonavicular coalition. This article delves into the causes, symptoms, diagnosis, and treatment options for calcaneonavicular coalition, offering a comprehensive understanding of this specific foot condition.
What is Calcaneonavicular Coalition?
Calcaneonavicular coalition is a type of tarsal coalition, a condition where there is an abnormal connection between two bones in the foot. Specifically, this coalition occurs between the calcaneus (heel bone) and the navicular bone, which is located on the top of the midfoot. This abnormal connection can be composed of bone, cartilage, or fibrous tissue, leading to restricted movement and potential foot pain.
Calcaneonavicular Coalition vs. Tarsal Coalition
While calcaneonavicular coalition refers specifically to the connection between the calcaneus and navicular bones, tarsal coalition is a broader term that includes any abnormal connection between the tarsal bones of the foot. Tarsal coalition may also involve other bones such as the talus, cuboid, or cuneiform bones. Understanding the specific nature of calcaneonavicular coalition is crucial for accurate diagnosis and treatment.

Common Symptoms
The symptoms of calcaneonavicular coalition can vary widely from person to person. Some individuals may remain asymptomatic throughout their lives, while others may experience significant discomfort. Common symptoms include:
- Foot Pain: Often experienced on the outer side of the foot and can worsen with activity.
- Stiffness: Reduced range of motion in the foot, especially noticeable when trying to move the foot side-to-side.
- Flatfoot: A decrease in the arch of the foot, leading to a flatfoot appearance.
- Frequent Ankle Sprains: Due to instability caused by the coalition.
When to Seek Medical Attention
If you experience persistent foot pain or stiffness that affects your daily activities, it is advisable to consult a healthcare professional. Early diagnosis and intervention can significantly improve outcomes and prevent further complications.
Causes of Calcaneonavicular Coalition
The exact causes of calcaneonavicular coalition remain largely idiopathic, though there are several hypothesized origins. It is predominantly considered a congenital condition, meaning it is present at birth due to genetic factors. During fetal development, the bones in the foot may not separate properly, leading to the formation of a coalition. In some cases, calcaneonavicular coalition may not become symptomatic until later in life, particularly during adolescence when the bones begin to ossify and undergo stress from increased activity levels.
Diagnosing Calcaneonavicular Coalition
Diagnosis of calcaneonavicular coalition typically involves a combination of clinical evaluation and imaging studies.
Clinical Evaluation
A thorough physical examination is essential. The healthcare provider will assess the foot's range of motion, observe any visible deformities, and inquire about the patient's symptoms and medical history.
Imaging Techniques
- X-rays: Initial imaging often includes X-rays to identify any visible abnormalities in the bone structure. However, calcaneonavicular coalition may not always be apparent on plain X-rays.
- CT Scan or MRI: These advanced imaging techniques provide detailed views of the bones and soft tissues, offering more accurate detection of the coalition and its specific characteristics.

Book an AppointmentTreatment Options for Calcaneonavicular Coalition
The treatment approach for calcaneonavicular coalition depends on the severity of symptoms and the impact on the patient's quality of life.
Non-Surgical Treatments
For mild cases or individuals who prefer conservative management, non-surgical treatments can be effective:
- Orthotics: Custom-made shoe inserts can help distribute pressure more evenly across the foot and provide support.
- Physical Therapy: Exercises to improve strength and flexibility, along with manual therapy techniques, can alleviate symptoms.
- Pain Management: Over-the-counter pain relievers or anti-inflammatory medications may be recommended to manage pain and swelling.
Surgical Intervention
In cases where conservative treatments fail to provide relief, surgery may be considered. The surgical options include:
- Coalition Resection: This procedure involves removing the bony or fibrous bridge between the calcaneus and navicular bones, thereby restoring mobility.
- Arthrodesis: In more severe cases, where significant joint degeneration has occurred, fusion of the affected joint may be necessary to alleviate pain and improve function.
Post-Treatment Recovery and Management
Recovery from calcaneonavicular coalition treatment, particularly surgery, requires careful management to ensure optimal outcomes.
Post-Surgical Care
- Immobilization: Following surgery, immobilization with a cast or boot is often necessary to facilitate healing.
- Rehabilitation: A structured rehabilitation program, including physical therapy, is crucial for regaining strength and flexibility.
- Follow-Up Appointments: Regular check-ups with the healthcare provider ensure that healing progresses as expected and any complications are addressed promptly.
Long-Term Management
Even after successful treatment, ongoing management may be necessary to prevent recurrence or manage any residual symptoms. This may include the continued use of orthotics, regular exercise, and attention to footwear choices.
Frequently Asked Questions
1. What are the symptoms of calcaneonavicular coalition?
Symptoms may include foot pain, limited mobility, and foot deformities, indicating a condition requiring evaluation and management.
2. What causes calcaneonavicular coalition?
Calcaneonavicular coalition is a congenital condition caused by abnormal fusion of the calcaneus and navicular bones in the foot, leading to functional limitations.
3. How is calcaneonavicular coalition diagnosed?
Diagnosis typically involves clinical evaluations, imaging studies such as X-rays or MRIs to visualize the coalition and assess its impact on foot function.
4. What treatment options are available for calcaneonavicular coalition?
Treatment may include physical therapy, orthotic devices, and in severe cases, surgical intervention to relieve symptoms and improve foot function.
5. What are the complications of calcaneonavicular coalition?
Complications may include chronic foot pain, limited mobility, and the need for ongoing management if not effectively addressed.
