Alignment: Surgical changes of a distal ulna resection (Darrach procedure) with expected mild osseous edema at the surgical site.
Fluid:
Carpus effusion: Trace free. Synovial thickening: Mild. Intra-articular body: Absent.
Distal radioulnar joint effusion: Soft tissue thickening and postoperative synovial compartment expansion in the distal ulnar resection site.
Intrinsic ligaments:
Scapholunate: Central membranous perforation.
Lunotriquetral: Intact.
Ulnar side:
Triangular fibrocartilage ligament: Disc degeneration. Focal tears along the ulnar aspect of the central disc. Postoperative changes of the peripheral ulnar-sided attachment of the disc to the adjacent pseudocapsule and extensor carpi ulnaris sheath. Susceptibility artifact from sutures.
Lunate facet: Type II facet.
Hamate-lunate: Normal.
Ulnocarpal impaction: Absent now.
Extensor compartment:
I: Tendinopathy. Extensor pollicis brevis is not seen at the radial groove.
II: Trace fluid.
III: Normal.
IV: Normal.
V: Normal.
VI: Surgical changes of an extensor carpi ulnaris tendon transfer and postoperatively split portion of the tendon attaching to the distal ulna, intact. Mild tenosynovitis.
Flexor compartment:
Flexor retinaculum: Likely post carpal tunnel release.
Common flexor tendons: Normal.
Flexor policis longus tendon: Normal
Flexor carpi radialis longus tendon: Normal
Carpal tunnel: Likely previous postop change.
Median nerve: Mild increased signal, expected postop.
Guyon canal: Normal.
Articular:
Thumb carpometacarpal / Metacarpophalangeal joints: Mild osteoarthrosis.
Lesser carpometacarpal joints: Normal.
Scaphotrapeziotrapezoidal joint: Mild osteoarthrosis.
Pisiform-triquetral joint: Trace effusion.
Extrinsic ligaments:
Radial collateral ligament: Intact.
Ulnar collateral ligament: Postop changes proximally.
Dorsal intercarpal ligament: Intact.
Volar extrinsic ligament: Intact.
Bones: Chronic healed distal radius fracture with mild edema at the ulnar sided fracture site.
Muscles: Normal.
Vessels: Unremarkable.
Other: None.
