Summary

Ulnar impaction syndrome, characterized by wrist pain and specific radiographic signs, requires advanced imaging for diagnosis. Magnetic resonance imaging (MRI) is the preferred method for evaluating suspected ulnar impaction and ulnolunate impingement.

Area of Science:

  • Orthopedics
  • Radiology
  • Musculoskeletal Imaging

Background:

  • Ulnar impaction syndrome is a recognized wrist condition.
  • It typically presents with positive ulnar variance and degenerative changes in the distal ulna and carpal bones.

Observation:

  • Clinical and plain film findings often necessitate advanced imaging for differential diagnosis.
  • Arthrography and bone scintigraphy are useful, but MRI offers superior sensitivity and specificity.

Findings:

  • This study details imaging findings in four patients with surgically confirmed ulnar impaction.
  • Magnetic resonance imaging (MRI) demonstrated characteristic changes associated with ulnar impaction syndrome.

Implications:

  • MRI is the imaging modality of choice for diagnosing suspected ulnar impaction and ulnolunate impingement.
  • Accurate diagnosis through advanced imaging can guide appropriate treatment strategies for wrist pain.
