Lisfranc's tarsometatarsal fracture-dislocation

Area of Science:

• Orthopedic surgery
• Radiology
• Podiatric medicine

Background:

• Lisfranc's fracture-dislocation affects the tarsometatarsal joints.
• Diagnosis can be challenging due to subtle fracture presentations.

Observation:

• Radiographic review analyzed normal tarsometatarsal joint alignment.
• The second tarsometatarsal joint exhibits the most consistent alignment.

Findings:

• The second tarsometatarsal joint's alignment is a key indicator in diagnosing Lisfranc injuries.
• Variations in other joints are noted, but gross abnormalities and chip fractures aid diagnosis.

Implications:

• Understanding normal radiographic anatomy is crucial for accurate Lisfranc injury detection.
• Improved diagnostic accuracy can lead to timely and appropriate treatment.
• This knowledge aids clinicians in interpreting subtle radiographic findings.
