What to look for in hip (proximal femoral) fracture
- Subcapital fracture with full displacement.
- Broken Shenton's line.
Description by the image author (may be in another language): Negative " John Thomas sign " or "Throckmorton sign" displayed by a patient who sustained a femoral neck fracture on the left. This radiography sign occurs when the patient's penis points away from the injured side. Notice that "John Thomas sign" is joke, even though this image is not(!) a fake.
Educational case. The diagnosis comes from the image's documented source; the "what to look for" list describes the condition in general and is not a report of this individual image.
