Name that fracture, ideal imaging modality, and treatment including indication for operative repair:
That would be a classic scaphoid fracture. It should ideally be imaged first with a three-view x-ray (AP, lateral, and scaphoid view – 30 deg extension, 20 deg ulnar deviation), but an MRI is the most sensitive for occult fractures. CT with 1 mm cuts is also acceptable although less sensitive than MRI.
Treatment is typically non-operative with thumb spica cast immobilization. Over 90% of fractures can be managed this way. Indications for operative repair include: proximal pole fractures, displacement > 1 mm, 15 deg scaphoid humpback deformity, radiolunate angle > 15 deg, intra-scaphoid angle of 35 deg, comminuted fractures, unstable vertical / oblique fractures, and any fracture associated with a perilunate dislocation. Duration of casting varies from 3-5 months depending on location of the fracture. Importantly, don’t forget to cast / splint any suspected fracture and refer for prompt follow up for reimaging.
The only question that remains unanswered is how did Matt Egan’s scaphoid become so jacked up…
