An oblique # of the olecranon. If displaced proximally. The treatment is :

"Oblique fracture may need a lag screw, neutralization by tension band system or plate". - Apley's. Treatment of olecranon fracture : Treatment of olecranon fracture may be either conservative or surgical. Conservative treatment : Conserative treatment includes immobilization in above elbow slab. Indications are : Undisplaced fractures. ​Displaced fracture with displacement less than 2 nun. Surgical treatmentn : It is indicated in displaced fracture (> 2mm) and in avulsion fractures due to triceps pull. Methods of fixation are : Open reduction and internal fixation by figure of 8 tension band wiring (TB W) : It is the most commonly used method for olecranon fracture. This method is used for avulsion fractures : transverse fractures when the fracture is proximal to coronoid : and sometimes oblique fractures. Lag screw fixation (interfragmentary screw) : Used in comminuted fracture when the distal fragment is displaced anteriorly and in the oblique fracture. Plate and screw fixation with grafting : Displaced comminuted fracture where tension band wiring is not possible. Excision of the proximal fragments.
