Can ultrasound diagnose adductor muscle strain?

From the Research

Yes, ultrasound can effectively visualize adductor muscle strains. Ultrasound is an excellent imaging modality for evaluating soft tissue injuries in the groin and inner thigh area, including adductor strains, as supported by a recent study published in 2021 1. During the examination, the radiologist or sonographer can identify characteristic findings such as muscle fiber disruption, localized swelling, hematoma formation, and increased blood flow in the affected area.

The advantages of using ultrasound for diagnosing adductor strains include its ready availability, relatively low cost compared to MRI, ability to perform dynamic assessments during movement, and lack of radiation exposure. The procedure is typically quick and painless, taking around 15-30 minutes to complete. For optimal results, patients should wear loose clothing that allows easy access to the inner thigh area.

While ultrasound is highly effective for most adductor strains, very deep or subtle injuries might be better visualized with MRI, which may be recommended if symptoms persist despite normal ultrasound findings. A study published in 2025 2 highlights the importance of using ultrasound guidance for interventional procedures on the adductor longus muscle to minimize the risk of damaging neurovascular bundles.

Key considerations for using ultrasound to diagnose adductor strains include:

• The ability to identify characteristic findings such as muscle fiber disruption and localized swelling
• The advantages of ultrasound over other imaging modalities, such as MRI
• The importance of using ultrasound guidance for interventional procedures to minimize the risk of complications
• The potential need for additional imaging, such as MRI, if symptoms persist despite normal ultrasound findings.

Overall, ultrasound is a valuable tool for diagnosing and managing adductor muscle strains, and its use should be considered in the context of individual patient needs and circumstances, as discussed in a study published in 2023 3 and a case report published in 2024 4.
