Gartland Type-IV Supracondylar Humeral Fractures: Preoperative Radiographic Features and a Hypothesis on Causation.

Background: The diagnose of Gartland Type-IV (G-IV) supracondylar humeral fractures (SCHF) has been reported to only be possible via fluoroscopy intra-operatively.

Hypothesis: A preoperative radiographic fracture pattern can indicate a G-IV SCHF.

Patients And Methods: Retrospective qualitative analysis of radiographs and reduction techniques used in twenty-seven GIV SCHF.
