Capitellar Fracture ICD-9
- 812.44 (fracture of humerus, condyle unspecified, articular process NO, lower epiphysis)
Capitellar Fracture Etiology / Epidemiology / Natural History
- Isolated capitellar fractures are uncommon.
- Women < men
- Mechanism of injury: When elbow is hyperextended the radial head forcefully shears off the capitellum during posterior dislocation.
Capitellar Fracture Anatomy
- Capitellar fractures often have extension into the trochlea (Buitton TG, JBJS 2009;91A:390).
- see Elbow Anatomy.
Capitellar Fracture Clinical Evaluation
Capitellar Fracture Xray / Diagnositc Tests
- A/P, lateral and oblique views of the elbow demonstrate fracture.
- CT scan: typically indicated to fully asses fracture. 3D reconstructions with radius and ulna subtracted are beneficial.

Capitellar Fracture Follow-up Care
- Post-op: compressive dressing, elevation
- 1 week: Start PT focused on ROM and strengthening. AAROM, PROM. AROM, free weights start at 3 weeks.
- 6 weeks: progressive sport specific activity.
- 3 months: Return to sport / full activities.
