Case Study: Navicular Fracture in a Young Footballer.

Case Study: Navicular Fracture in a Young Footballer

In high-intensity sports like football, foot injuries can be debilitating and require careful management to ensure a safe return to play. In this case, we explore the injury of a young semi-professional football player who sustained a navicular fracture following a forceful collision during training. This case highlights the critical steps in diagnosis, management, and rehabilitation of navicular fractures—an uncommon yet significant injury in athletes.

Patient Presentation:

The athlete, a young football player, was injured during a training session while attempting to intercept the ball. The collision occurred with his foot in a plantar flexed and inverted position, resulting in immediate sharp pain in the dorsal midfoot. He was immediately substituted, and initial assessment revealed:

Pain in the midfoot region.

Swelling and tenderness over the dorsal aspect of the foot.

Limited range of motion in the affected foot, particularly during dorsiflexion.

Physical Examination and Diagnosis:

Upon clinical examination, notable findings included swelling on the dorsal aspect of the foot and tenderness specifically over the navicular bone, a key structure in foot mechanics. Passive dorsiflexion of the first metatarsal exacerbated the pain, indicating potential structural injury.

An X-ray of the foot was obtained, with both anteroposterior and lateral views showing a fracture localized to the dorsal aspect of the navicular bone, consistent with a Sangeorzan’s Classification Type I fracture. This type of fracture involves an avulsion at the tuberosity, where ligaments and tendons attach to the navicular bone.

Initial Management Plan:

Navicular fractures, though rare, can have profound implications for an athlete’s foot biomechanics and long-term performance. Prompt and appropriate treatment is essential to avoid complications like non-union or avascular necrosis.

The immediate treatment plan for this athlete was as follows:

1. RICE Protocol: Rest, ice, compression, and elevation were implemented to manage pain and swelling during the acute phase.

2. Immobilization: The player was referred to a specialist at NITOR (National Institute of Traumatology & Orthopaedic Rehabilitation) for further consultation. A short leg cast was applied to immobilize the fracture and promote healing.

3. Non-Weight Bearing: The athlete was instructed to avoid putting any weight on the affected foot for the first 4 weeks, a critical period for fracture healing.

4. Pain Management: NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) were prescribed to manage pain and inflammation during the initial phase of treatment.

Rehabilitation and Recovery:

Rehabilitation following a navicular fracture is a structured, phased process designed to promote healing while maintaining the athlete’s overall conditioning.

Early Phase (0-6 weeks): The focus is on protecting the fracture site. During this period, the athlete can engage in non-weight-bearing activities such as swimming or upper-body conditioning exercises to maintain fitness. The goal is to prevent deconditioning while avoiding stress on the fracture.

Mid Phase (6-10 weeks): Once X-rays confirm sufficient healing, gradual weight-bearing will be introduced. At this stage, range of motion exercises and isometric strengthening of the muscles around the foot and ankle will begin. Careful attention will be paid to avoid overloading the healing bone.

Late Phase (12+ weeks): The final stage of rehabilitation focuses on progressive strengthening of the foot and ankle, along with proprioceptive training to restore balance and coordination. At this point, the athlete will begin sport-specific drills, aiming for a gradual return to full training while monitoring for any complications such as non-union or avascular necrosis.

Long-Term Considerations and Complications:

Navicular fractures, especially Sangeorzan’s Type I fractures, are less common in football but can have serious implications if not managed properly. The navicular bone plays a crucial role in maintaining foot stability and transferring forces during running, jumping, and cutting—key movements in football.

One of the primary concerns in this injury is the potential for non-union, where the bone fails to heal properly, and avascular necrosis, a condition where blood supply to the bone is compromised, leading to bone death. These complications can severely impact long-term mobility and performance.

Thus, close follow-up is essential to monitor healing progress. Regular imaging, coupled with careful progression through rehabilitation, will give the athlete the best chance for a full recovery.

Discussion:

Navicular fractures, though not common in football, pose a significant risk to athletes due to their role in maintaining foot mechanics. The Sangeorzan Type I avulsion fracture, seen in this case, involves a disruption at the site of ligamentous attachment, which, if not treated properly, can compromise foot stability.

Current literature supports the conservative management of stable navicular fractures, with immobilization and non-weight-bearing protocols being standard in the early phase. However, the potential for complications like non-union and avascular necrosis makes long-term follow-up and imaging critical for athletes aiming to return to high-performance sports.
