[Segond's fracture at the knee level]

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Radiology

Background:

• Segond's fracture is a specific type of avulsion fracture.
• Its association with internal knee derangement, particularly anterior cruciate ligament (ACL) injury, remains debated.

Purpose of the Study:

• To investigate the diagnostic accuracy of Segond's fracture in identifying associated anterior cruciate ligament injuries.
• To clarify the relationship between Segond's fracture and ligamentous knee injuries.

Main Methods:

• Retrospective analysis of twelve patients diagnosed with Segond's fracture.
• Ten patients underwent surgical treatment, with intraoperative assessment for ACL integrity.
• Two patients were evaluated clinically and radiologically for ligamentous injury.

Main Results:

• Ten out of twelve patients with Segond's fracture had associated anterior cruciate ligament injuries.
• Clinical and radiological assessments confirmed ligamentous injury in the remaining two patients.
• The study confirms Segond's fracture as a strong indicator of ACL injury.

Conclusions:

• Segond's fracture is a highly reliable indicator of concomitant anterior cruciate ligament injury.
• This finding supports the classification of Segond's fracture as pathognomonic for ACL tears.
• Surgical evaluation is recommended for patients with Segond's fracture to assess for ACL injury.
