Occult Fracture of the Fibula: One Case Report.

PMID 36108246WHAT IT FOUND
In one adult, persistent ankle pain and a normal x-ray hid an occult distal fibula fracture found only by MRI.
Cast fixation and protected weight bearing healed it. This is one case, not evidence.
Key findings
01The patient had persistent right lateral malleolus pain, a normal x-ray, and an MRI that later showed a distal fibula fracture with good alignment.
02After plaster fixation, oral painkillers, cast removal after one and a half month, and a further one and a half months without weight bearing, the fracture healed and ankle function recovered.
03Nursing measures described were padding and regular skin checks over the malleoli and heel, replacing loosened plaster, and teaching lower-limb contractions during immobilization.

What it does not show
The case describes only one patient, so it cannot show that MRI, cast fixation, or nursing measures caused healing. There was no comparison group, no standard outcome score, and no defined long-term follow-up. The patient initially refused MRI, so the timeline may not reflect usual practice. The report does not state analgesic dose or exact follow-up intervals. The Discussion cites other studies for imaging accuracy, but this case does not test them.
Declared interests
The authors report no funding and no conflicts of interest.
The easy way to misread this
Do not read this as proof that MRI or cast fixation works for occult fibula fractures. It is one case with no comparison, and the authors' MRI recommendation is not tested here.
