|Because of the biplanar
angulation and curvature of the distal radius, the alignment of
intraarticular distal radius fractures may be difficult to estimate by

|This patient presented with
persistent wrist pain, swelling and stiffness one year out from closed
reduction and external fixation of a n intraarticular distal radius
|No prior films were
available. Plain films suggested a depressed section of the radial edge
of the lunate fossa and loss of dorsal tilt.
|On first glance, 3D CT
reconstruction looked favorable for possible simple dorsal opening
wedge corrective osteotomy.
|Below, a fly-around video of the 3D reconstruction:|
|Digitally hiding the carpal bones obstructing the view of the distal radius shows a much more significant articular defect. In these views, the
proximal cortex of the scaphoid remains as a yellowish shell - it could not be cleanly
removed because it is in bony contact with the dordal lip of the radius.
