Scaphoid non-union

Case contributed by Dr Heba Mohamed

Presentation

Patient with scaphoid fracture 7 months ago.

Patient Data

Age: 20 years
Gender: Male
CT

Herbert screw internal fixation. 

Clearly defined fracture of the scaphoid waist. Mild reduction of density of the proximal scaphoid bone with small cysts.

Case Discussion

Fractures of the scaphoid waist represents 70% of the scaphoid fractures. Scaphoid mal-union is defined as a visible fracture remaining after 4 months with casting. 

Scaphoid non-union is considered if the fracture line is identified after 7 months to a year.

In this particular case the scaphoid fracture line is still identified after 7 months with Herbert screw fixation. Early avascular necrosis of the proximal scaphoid is demonstrated as reduced bone density with multiple areas of cystic changes.
