I broke my radial head and after a year - I still can’t straighten my arm without it clicking. I got an MRI and this is what he said.
There is a large focal chondral flap of the radial head articular cartilage measuring 1.2 cm (ML) x 1 cm (AP)
best appreciated on image 9 series 5 and image 13 series 4 (saved snapshot). This is slightly uplifted and is
unstable. The there is minor chondral fibrillation of the radial head and capitellar articular cartilage.
Ulnohumeral articular cartilage is preserved. No discrete intra-articular body.
The radial collateral and lateral ulnar collateral ligaments are intact.
Common extensor tendon origin is normal.
Common flexor tendon origin and ulnar collateral ligament are normal.
The biceps, brachialis, triceps tendon insertions are normal.
The ulnar nerve is normally located within the cubital tunnel and has normal appearances.
Elbow musculature is of normal volume and signal.
Opinion:
Small elbow joint effusion.
United intra-articular fracture radial head with impaction at the anterolateral margin with a large chondral flap
as described.
Intact radial and lateral ulnar collateral ligament.
