A Personalised Percutaneous External 3D Guide for Scaphoid Fixation
A Personalised Percutaneous External 3D Guide for Scaphoid Fixation
The investigators want to analyse the advantages of using a 3D constructed prototype from a
 previous CT Scan to model an external customised guide por percutaneous Scaphoid fixation.

 The investigators hypothesise that the usage of this device will shorten surgery time,
 radiation for the surgery team and optimise the percutaneous screw trajectory inside of the
 scaphoid bone.
To carry out this analysis the investigators will recruit 10 patients who present with an
 acute fracture of the Scaphoid bone type B1 and B2 (Herbert Classification).

 A CT Scan will be performed and a 3D exoesqueleton model printed, previously deciding the
 position of the fixation screw inside of the bone and adding a cannulated sleeve in the volar
 aspect of the exoesqueleton to insert the initial positional guide wire for surgery.

 Surgery time, surgery radiation exposure and screw positioning will be recorded and compared
 to 10 control patients operated following standard procedure.
Inclusion Criteria:

 -  Acute scaphoid fracture (Herbert B1 B2)

 Exclusion Criteria:

 -  Concomitant fractures
