Instability and synovitis of the lesser metatarsalphalangeal (MTP) joints is a significant cause of forefoot pain. Plantar plate imaging traditionally has been through MRI and fluoroscopic arthrography. We have described ultrasound arthrography as a less resource-intensive technique without radiation exposure. We report the correlation between ultrasound arthographic and surgical findings. Patients with lesser MTP joint instability and pain underwent ultrasound arthrography by a consultant musculoskeletal radiologist. The main finding was the presence of a full or partial tear of the plantar plate. In some patients the location of the tear along with its size in the long and short axis was also reported. Authors who were not involved in the imaging or surgery reviewed the operation notes of patients who underwent surgery to identify Whether a partial or full thickness tear was identified Size and location of the tear The accuracy of ultrasound arthrography was calculated using surgical findings as the standard.Introduction:
