Isolated tarsal navicular fracture dislocation: a case report

Area of Science:

• Orthopedic surgery
• Traumatology
• Podiatric medicine

Background:

• Injuries to the midtarsal joints are uncommon, presenting as fractures, subluxations, or dislocations.
• Isolated dislocations of the tarsal navicular bone are particularly rare and lack comprehensive understanding.
• Existing literature on these injuries is limited, with few case reports detailing mechanisms and treatments.

Observation:

• This case report focuses on isolated tarsal navicular dislocations, a rare injury.
• It highlights a specific treatment approach using external fixation.
• The described method utilizes pins placed in the calcaneum, differing from previous reports.

Findings:

• The study emphasizes a modified external fixation technique for managing isolated tarsal navicular dislocations.
• This approach involves percutaneous fixation with pins inserted into the calcaneum.
• This method is presented as an alternative to previously described external fixation techniques.

Implications:

• This case report contributes to the limited understanding of rare midtarsal joint injuries.
• It offers a potentially effective treatment alternative for isolated tarsal navicular dislocations.
• The findings may guide orthopedic surgeons in managing complex foot trauma.
