Segond fracture: lateral capsular ligament avulsion
The Journal of Orthopaedic and Sports Physical Therapy
|February 1, 1997
Summary
Physical therapists need radiology training to recognize Segond fractures, a type of avulsion fracture. Recognizing this fracture is crucial as it often indicates an anterior cruciate ligament tear.
Area of Science:
- Radiology
- Orthopedic Surgery
- Physical Therapy
Background:
- Physical therapy curricula increasingly emphasize radiology, yet many practitioners lack formal instruction.
- Evolving healthcare demands necessitate physical therapists' understanding of radiographic findings and their clinical significance.
Purpose of the Study:
- To review literature and comment on Segond fractures (avulsion fractures of the lateral tibial condyle).
- To highlight the importance of recognizing Segond fractures in clinical practice.
Main Methods:
- Literature review and commentary on Segond fractures.
Main Results:
- Segond fractures result from forced internal tibial rotation with knee flexion.
- This mechanism causes avulsion of the lateral tibial capsule and meniscotibial ligament.
- Segond fractures are a radiographic sign often associated with anterior cruciate ligament disruption.
Conclusions:
- Physical therapists must be able to identify Segond fractures.
- Recognition of Segond fractures is critical for diagnosing associated knee injuries, particularly ACL tears.
