Abstract
Objective: Fractures of orbital rims are common and restoration of these fractures back to
its normal anatomic form is essential to maintain the function and aesthetics of the eyes.
Low profile miniplates are the rigid fixation device of choice for such fractures. But in case
of sagittal and grossly displaced fractures of orbital rims it is difficult to achieve stability by
using miniplate osteosynthesis. The low profile miniplates may not be able to withstand
the forces to reduce this kind if grossly displaced fractures, another stable option needs to
be considered in these situations.
Case presentation: This case report presents a simple and effective technique of reduction
and fixation of an oblique fracture of infraorbital rim fracture using lag screw principle.
A standard titanium screw of 2 mm diameter and 10 mm length is being used in the
described technique for stable fixation of fractured segments.
Conclusion: The technique is simple, hardware’s are easily available and can be practised
in emergency circumstances where newer advanced technologies are not available
