Fracture Medial Epicondyle/Condyle Humerus
- The ossification centre of medial epicondyle of humerus appears between 5 - 7 years and fuses to the shaft (diaphysis) between 16-20 years.
- In older patients (> 7yr.) the medial epicondyle fragment is usually easily identified radio graphically. However radiographic interpretation is very difficult in younger patients
- In either case, assessment of minimally displaced fractures may be facilitated with comparison views of both elbows .
- Ulnar nerve runs in a groove in the posterior aspect of medial epicondyle and so it is most commonly involved nerve in the medial epicondylar fracture
- But it is important to note that the involvement is immediate not tardy (late) as in fractures of lateral condyle humerus.
- Medial epicondylar fractures are most commonly associated (~50%) with elbow dislocations.
- These fractures are usually managed non operatively until they become entrapped in joint or >1cm displaced.
