Of all the misalignments of the first ray of the foot, the dorsal bunion is the least known. The dorsal bunion deformity consists of the elevation of first metatarsal head, plantar flexion contracture at the first metatarsophalangeal joint, and dorsiflexion contracture of the tars-metatarsal joint. The deformity presents most commonly after clubfoot treatment but can also be a sequela of various neuromuscular foot conditions, including poliomyelitis and cerebral palsy. We report two case of dorsal bunion. A 30 year-old man and a 14 year-old girl, the both are an iatrogenic pathology secondary to a clubfoot surgery. Treated by different surgery technique and the results were satisfied in the two cases. The dorsal bunion results from a musculo-ligament imbalance at the level of the first ray, which involves 4 muscles: the long fibular, the flexor of the hallux, the anterior tibial and the triceps sural. The flexibility of the navicular-cuneate and cuneo-metatarsal joints also plays an important role. It was Lapidus who coined the term "dorsal bunion" and developed an operative technique that bears his name. Several interventions have been proposed in the literature, the majority of which stem from Lapidus's intervention.
