SURGICAL TECHNIQUESURGICAL TECHNIQUE Under the guidance of image intensifier
closed reduction achieved by ligamentotaxis either using longitudinal traction or femoral distractor
Incision was made as large as necessary for the insertion of the plate,far from fracture site
Either T Buttress plate / L buttress plate with or without 4.5 mm narrow DCP slide in sub muscular plane extraperiostealy
The plate was then fixed with a minimum
of three screws on either side of the
fracture using image intensifier
