Osteochondral fractures of the glenoid fossa of the ulna in children: review of four cases.

Osteochondral fractures of the glenoid fossa of the ulna are exceptional injuries in children. These lesions can present diagnostic problems because the fragments are often radiolucent. We followed four children for 3, 6, and 24 months and 12 years, respectively. The elbow was definitely dislocated in two, and was probably dislocated in two other, children. The most reliable paraclinical examination was conventional sagittal tomography. Open revision is mandatory for reduction of the fracture and, when performed early, may lead to excellent functional results.
