Figure 7

Lower limb deformity in a 7-year-old girl (case 3) undergoing Burosumab therapy. Full long leg standing radiographs and lower limb deformity analysis were obtained prior (A) to initiation, as well as during follow-up appointments. Valgus deformity was observed and a temporary hemiepiphysiodesis procedure performed in both legs (x-ray 2 months postoperative) despite persistent rachitic status (B). Normalization of MAD in one leg occurred sooner (C). As a sign of valgus deformity rebound, a mild recurrence of lateralization of the MAD after successful guided growth surgery despite Burosumab therapy was observed at the last follow-up 12 months after plate removal (D).
