Capitellar fractures result from shearing and wedging forces transmitted to the elbow that create complex injury patterns that are difficult to stabilize. The fracture often extends into the trochlea and is associated with posterior comminution of the humerus and soft tissue injury. Diverse fixation techniques are required to restore the anatomy perfectly to ensure elbow function is regained. ⋯ Level 4; Case series, treatment study.

Radial head fractures: loss of cortical contact is associated with concomitant fracture or dislocation.
Among radial head fractures displaced greater than 2 mm (Broberg and Morrey modified Mason type 2), separation (complete loss of cortical contact) of at least 1 radial head fracture fragment is associated with a complex injury pattern, meaning that there are other concomitant elbow fractures or ligament injuries. ⋯ 4, Retrospective case series, Treatment study.

Large coronal shear fractures of the capitellum and trochlea treated with headless compression screws.
The purpose of this study is to retrospectively evaluate the clinical outcomes of 18 patients with large coronal shear fractures of the capitellum and lateral trochlea that underwent open reduction and internal fixation with headless compression screws. ⋯ 4.

Tetracycline labeling as a measure of humeral head viability after 3- or 4-part proximal humerus fracture.
Specifically located humeral head biopsies from three-part proximal humerus fractures taken at the time of hemiarthroplasty will show greater tetracycline labeling under fluorescent microscopy than those biopsies taken from four-part fractures. Additionally, biopsies from younger patients would show greater fluorescence than older patients. ⋯ Basic Science Study.
