FROM MY PT SCHOOL NOTES · DIAGNOSTIC IMAGING · UNIT 2 · CHAPTER 09
Wrist and hand
Review the relevant anatomy and imaging question before deciding what the finding may mean for rehabilitation.
Key imaging concepts
- Follow carpal alignment, the distal radius/ulna, metacarpals and phalanges in multiple views.
- Scaphoid injury after FOOSH may be radiographically occult early, and the blood supply makes delayed recognition consequential.
- Consider fracture alignment, scapholunate interval, carpal rows and cortical breaks, while recognizing that plain films do not show most ligament/tendon lesions directly.
PT clinical connection
Persistent anatomical snuffbox tenderness after a compatible injury warrants an appropriate immobilization/imaging or referral pathway.
High-yield distinction
Two distinct wrist questions: Check carpal alignment on regular views, but recognize that a scaphoid fracture may be occult despite appropriate projections.
