✅ Segond Fracture
1️⃣ Segond Fracture and Associated Injuries
- Associated Findings: Segond fractures are linked to ACL tears, MCL tears, medial meniscus tears, and posterolateral corner injuries.
- Indicator of ALRI: Recognized as a marker for anterolateral rotatory instability (ALRI) and a predictor of severe ligamentous injury, particularly to the ACL.
2️⃣ ALL Injuries and Segond Fractures
- Prevalence in ACL Injuries: ALL injuries occur in about 40% of ACL injuries, with Segond fractures being a subset.
- Fracture Characteristics: The fracture fragment is thin, ovoid, vertically oriented, and situated anterolaterally along the lateral tibial plateau behind Gerdy’s tubercle.
3️⃣ Involvement of ITB and ALL
- Attachment to Fracture: In 94% of cases, the posterior fibers of the ITB and the lateral capsule (ALL) attach to the Segond fracture.
- Tibial Insertion of ALL: The tibial insertion of the ALL is consistently located between the fibular head and Gerdy’s tubercle and positioned between 4.0 and 7.0 mm below the tibial plateau.
