Tips for scanning Baker’s Cyst in a longitudinal orientation
The intersection of the medial gastrocnemius and semimembranosus muscles is called the Baker’s cyst neck position.
Check out these 3 tips to scan Baker’s cyst (longitudinal scan)
- Position the patient prone.
- Place the transducer longitudinal over the intersection of the medial gastrocnemius and semimembranosus muscles.
- Identify the following structures:
- Semimembranosus muscle: Inserting onto the tibial plateau.
- Popliteus muscle: Located immediately distal to the semimembranosus.
- Semitendinosus muscle: Located on top of the semimembranosus.
- Posterior horn of the medial meniscus: Located between the tibia and femur.
- Medial gastrocnemius muscle: Overlapping the distal part of the semimembranosus and semitendinosus muscles.
