Poster Information
Abstract: Background: Shoulder ultrasound is considered the first line investigation to detect pathology of the rotator cuff. Many orthopaedic surgeons are reliant on it for pre-operative assessment. Its accuracy in detecting rotator cuff pathology has not been investigated in our trust.

Methods: We compared, retrospectively, the ultrasound and the arthroscopic findings for 40 patients from June 2019 till March 2020 performed at West Hertfordshire NHS Trust. Of the 40 patients’ records, twenty-one had medical records which were available to compare the findings with the arthroscopy reports.

Results: Eleven patients (52%) from our sample had full thickness rotator cuff tears on arthroscopy, all except one (91%) were detected on ultrasound.

Six patients (29%) had no rotator cuff pathology on ultrasound which correlated with the arthroscopic findings. Partial tears of rotator cuff tendons were diagnosed in three patients out of four. The fourth patient had a tiny rotator cuff tear on ultrasound which was not identified at arthroscopy.

There was a good diagnostic yield of long head of biceps pathology and calcifications within the shoulder joint.
Summary: Ultrasonic findings were accurate in the diagnosis of full-thickness tears (91%) but less accurate in the diagnosis of partial thickness tears (75%) in our local study. These findings concur with the literature on this subject. Many factors are likely to influence US outcomes such as operator technique, patient mobility and pain threshold.
