Abstract

The triceps brachii inserted into the posterior third of the olecranon and the proximal ulna separated the olecranon, the brachialis inserted into the coronoid process of the ulna produced tensile forces across the elbow joint during contraction, so as to separate the coronoid, thus resulting in complex fracture of proximal ulna. According to the AO principle of articular fracture management, ORIF using anatomical locking plate was performed, one day after the injury, without any complication.

Highlights

As in other articular fractures, the aims of treatment, as defined by AO group, are to restore the articular surface, achieve absolute stability of the fracture, and commence early active motion, and, the restoration of function without pain [2,3,4]. This is only possible with ORIF such as TBW, plate and intramedullary fixation techniques as well as fragment excision with triceps advancement [4,5,6,7,8]
The TBW described by Weber and Vasey [4] has been widely used in the ORIF of olecranon, plate fixation has been used principally for the management of comminuted olecranon fractures in which TBW is not appropriate [5,9]
This report describes heterotopic ossification (HO) as a complication related to the internal fixation of a proximal ulna comminuted fracture

Summary

Introduction

Olecranon fractures comprise approximately 10% of all fractures around the elbow [1].They vary in their complexity from relatively straightforward transverse fractures to comminuted and unstable configurations.As in other articular fractures, the aims of treatment, as defined by AO group, are to restore the articular surface, achieve absolute stability of the fracture, and commence early active motion, and, the restoration of function without pain [2,3,4].This is only possible with ORIF (open reduction and internal fixation) such as TBW (tension b and wiring), plate and intramedullary fixation techniques as well as fragment excision with triceps advancement [4,5,6,7,8].The TBW described by Weber and Vasey [4] has been widely used in the ORIF of olecranon, plate fixation has been used principally for the management of comminuted olecranon fractures in which TBW is not appropriate [5,9].Plates are generally applied to the dorsal surface of the ulna because this is the tension side of the olecranon which makes the construct most biomechanically sound, and because screws can be passed into the coronoid [10,11].
