By the time she reached me she’d done the full lap. Foot strengthening. Mobilisations. Expensive custom orthotics. Shockwave. Dry needling. None of it moved the needle. Her running told the same story every time. Fine off the line but pain starting 2 to 3 km into a 5 km run. Every session. She’d already had an MRI from a previous healthcare provider. In a classic case of ‘junk in = junk out’ - there wasn’t much on the report. The referral: ‘ankle pain’, though ideally it would have read ‘dorsal midfoot in runner near palpable prominence at talonavicular joint’. C’mon people…. Radiologists deserve some stories sometimes! Despite an allegedly radiologically-boring midfoot, the report did give away the big clue in the hindfoot: an osseous subtalar tarsal coalition across the sustentaculum tali (without significant stress reaction). Nobody paid it much attention, presumably because nobody was sure what it meant. The beak is a symptom, not a diagnosis A dorsal talar beak is a bony outgrowth on the upper aspect of the talar head, projecting toward the talonavicular joint. It is a traction osteophyte. It forms where the dorsal talonavicular ligament and capsule pull repeatedly on the talus; the foot’s attempt to remodel around mechanics that have gone wrong upstream [1]. The alternative explanation is mechanical: the navicular rides up over the talar head and lifts the periosteum, and bone fills the gap [2]. Either way, the beak is not the villain, it is the breadcrumb. The question worth asking is what is driving it. In a young adult the answer is often a restricted subtalar joint, and the usual culprit is tarsal coalition. What a coalition actually is
