Case: We present a case of a pure superior wall acetabular fracture in an US soldier, caused by a collapsing wall. Although Letournel and Judet classified this pattern as a rare variant of a posterior-superior wall acetabular fracture, it shares features of several patterns and the treatment more closely follows that of the anterior-based elementary patterns.
Conclusion: The mechanism, incidence, and long-term outcomes of this fracture remain unknown, but improved recognition and proper classification may help to guide treatment. This case highlights 1 patient with this unique pattern and outlines its management and short- to mid-term outcome.
