Monteggia fracture dislocation represent approximately 1%–2% of forearm fractures. It is defined as fracture of proximal ulnar shaft with radial head dislocation.The aim of treatment of a Monteggia fracture dislocation is stable rigid fixation of fractured ulna which reduces the dislocated radial head .Any residual angulation of the ulna fracture predisposes to subsequent redislocation or subluxation of the radial head.This stable rigid fixation can be done with open reduction and internal fixation with dynamic compression plating.We present a case study of Monteggia fracture dislocation treated with open reduction and internal fixation with 3.5mm dynamic compression plate.Once ulnar length and alignment  was restored,radial head got reduced which was confirmed under fluoroscopy.It was  followed by immobilization in hyperflexion for 3 weeks.The patient was followed up at the end of  6 weeks following injury and gradual elbow joint  range of motion was begun.Further follow up at 3 months,6 months and 1 year showed fully united fracture with complete return of elbow range of movements.
