Abstract

BackgroundPost-sprained ankles may sustain ligamentous tear, chondral defect, or osteochondral lesions (OCL). Being widely available and does not depend on high-end machine, the aim of this study was to assess the value of high resolution multi-detector CT arthrography (CTA) in detection of various ligamentous tears, chondral defects, and osteochondral lesions in case of sprain-related persistent ankle pain.ResultsThere were 34 (68%) cases of ligamentous injury, most of which had single ligament affection whereas some cases demonstrated multi-ligamentous injury, and the total number of individual injured ligaments was 42 ligaments. There were 36 cases (72%) which had either chondral or osteochondral defects; the total number of OCL was 21 lesions and the total number of segmental cartilage defects was 20.ConclusionThis study emphasized the diagnostic importance of multi-detector CTA in sprain-related ankle pain. In persistent post-sprained ankle pain, multi-detector CTA is a helpful imaging modality which could be utilized for detection of OCL, chondral defects, and various ligamentous tears.

Summary

Introduction

Post-sprained ankles may sustain ligamentous tear, chondral defect, or osteochondral lesions (OCL). Being widely available and does not depend on high-end machine, the aim of this study was to assess the value of high resolution multi-detector CT arthrography (CTA) in detection of various ligamentous tears, chondral defects, and osteochondral lesions in case of sprain-related persistent ankle pain. Post-sprained ankles may sustain one or more intra-articular injuries as ligamentous tear, chondral defect, and osteochondral lesions (OCL) [1–4]. Non-arthrographic imaging tools including ultrasonography and conventional MRI can be utilized for assessment of ligamentous injuries; proper characterization of OCL needs arthrographic-based techniques. CT arthrography (CTA) is a helpful imaging tool which could be utilized in different joints especially the small ones. In the ankle, being a small joint, the imaging technique should have high
