1. Stener-like Lesions in Musculoskeletal MRI

    February 2025 Mark Awh, M.D.

    In this month’s Radsource Web Clinic, Dr. Mark Awh discusses MRI cases where an interposed structure prevents a torn ligament from healing with conservative management – from the classic Stener lesion in the thumb metatarsophalangeal joint to additional “Stener-like” lesions throughout the body. The radiologist plays a critical role in recognizing these conditions, which typically require operative treatment.
