It has been reported that the five metatarsal heads of the forefoot, the two sesamoid bones and the transverse metatarsal ligament under the first metatarsal head form the top of the second and third metatarsal heads. Analysis of Risk Factors Related to Hallux Valgus Combined with Pain Under the Second Metatar... The difference in metatarsal length is considered to be one of the important risk factors for hallux valgus complicated with pain under the second metatarsal head.[28] In the gait advancement stage, the relatively long small metatarsal bone easily causes mechanical overload under the metatarsal head. Then, the tibial sesamoid position was measured according to Hardy's protocol.[16] The forefoot length was assessed in the first metatarsal relative to the second metatarsal, and the patients were divided into three groups according to this length: In the minus index, the first metatarsal was shorter than the second, and the following metatarsals became progressively shorter. The multivariate logistic regression analysis showed that the length of the second metatarsal (OR = 1.078, 95% CI [1.051, 1.105]), the peak pressure of the second metatarsal head (OR = 1.607, 95% CI [1.342, 1.925]), HVA (OR = 1.068, 95% CI [1.028, 1.109]), IMA1-2 (OR = 1.222, 95% CI [1.044, 1.43]) and weight (OR = 1.044, 95% CI [0.983, 1.108]) were the risk factors for patients with hallux valgus with pain under the second metatarsal head.
