Hallux valgus is the deviation of the first metatarsal in varus and the big toe in valgus.

Through a retrospective study we analyzed 10 feet managed fr hallux valgus between January 2014 and March 2020. The average age was 14 years with female predominance. Patients reported pain and the deformation. Idiopathic origin was the most frequent. The average of M1P1 angle was 44.08°, the M1M2 angle was 14. 05°.The mean DMAA value was 18.8°, and the mean M1M5 angle was 32.4°.

Sesamoid class 1 was found in six feet (60%), four others had sesamoid class 2 (40%). Seven feet had dislocated or subluxated non-congruent metatarsophalangeal joints with a percentage of 70%. The average medial arch measurement was 110°, the average angle of attack of M1 was 20.87°.

All patients underwent uneventful surgery. McBride surgery was performed on two feet. A stabilized re-axation osteotomy with K-wires associated with a release of the abductor hallux was performed in six feet out of the other eight. In these eight, 40% had a chevron osteotomy, 30% had a Mitchell Osteotomy and 10% had a modified Scarf Osteotomy.

They resumed walking on the heel immediately with a 6weeks boot cast.

The mean value of the M1P1 angle decreased from 44.08° pre-operatively to 15.46° post-operatively with a reduction rate of 64.92%.

Given the immaturity of the child's skeleton, the surgical treatment of hallux valgus must be as innocuous as possible.
