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.

Recognition of the proximal ulna dorsal angulation (PUDA) is important for anatomic reduction of proximal ulna fractures, nonunions, malunions, or osteotomies, especially when using newer straight precontoured ulnar plates. The purpose of this study was to characterize the PUDA in 50 patients with bilateral elbow radiographs. ⋯ Radiographic study.

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.
