Evaluation of the Effect of Ununion Percentage of Scaphoid on Stress and Displacement of Fragment Part of Scaphoid in Various Degrees of Wrist Extension with and without External Force

Conclusion The stress developed in scaphoid depends on the nonunion percentage of scaphoid and the amount of motion of wrist joint. It is better to use external fixation screw especially for conditions 3 and 6 (75% of union in middle and distal parts) to decrease the displacement of fragment parts and to decrease the stress applied on scaphoid in wrist extension. Type of Study and Level of Evidence Case study, level of evidence: III.
