Radial head dislocation (initially missed)

Case contributed by Gerry Gardner

Presentation

Returned to clinic 4 weeks post injury with deformity and decreased range of motion.

Patient Data

Age: 8 years
Gender: Female

The radial head is dislocated and surrounded by irregularly ossified material secondary to chronic dislocation.

Case Discussion

The radial head dislocation was not reported on the initial radiographs (not shown). Upon presenting again several weeks later with chronic complaints, marked calcification became also evident within the joint (possibly the annular ligament).
