“…In case of insufficient local tissues at the proximal phalanx base plantar aspect, a sling procedure may be performed. This can be accomplished with a suture passed behind the sesamoids, threaded through holes in the proximal phalanx, brought out through the skin, and secured on the toe dorsal aspect over a button [16][17][18][19][20][21] .…”

Case: A 34-year-old woman sustained a direct trauma to the left hallux during a fall. Radiographs showed a dorsal dislocation of the first metatarsophalangeal joint and a wide separation of sesamoid complex. Closed reduction was tried: postreduction radiographs displayed reduction of first metatarsophalangeal joint and a complete sesamoid complex dislocation. The patient was scheduled for surgery. Through a medial approach, open reduction together with plantar structures release and repair were performed. Functional and radiographic outcomes were satisfactory at the last follow-up. Conclusion: In case of a “headphones-like lesion” surgery is required, together with plantar structures repair.

“…Despite some authors reporting closed reduction of the IP joints of the hallux to be successful in some patients [ 11 , 12 ], this procedure usually fails, obtaining an incomplete reduction [ 1 , 9 ]. When performing closed reduction of the Miki Type 2, sesamoid interposition into the IP joint is the rule, transforming the lesion in a Type 1 [ 8 , 13 , 15 , 16 ], due to the invagination of the sesamoid-plantar plate complex into the IP joint. As the interposed sesamoid effectively “tightens” the intact collateral ligaments, thereby preventing closed reduction [ 3 , 12 , 18 - 20 ].…”

“…Recently one case of acute irreducible IP dislocation in plantar direction has been reported [ 13 ]. Neglected irreducible IP dislocation has once been reported in dorsal direction [ 11 ] but we have not found any case in the literature of neglected plantar IP dislocation of the great toe consistent with our Case 3 that is the first description in the literature.…”

Introduction: Irreducible dislocation of the great toe interphalangeal (IP) joint is a rare injury that has scarcely been reported in dorsal direction, but no reported in plantar direction. Closed reduction usually leads to sesamoid incarceration, making the reduction impossible. The purpose of this article is to review the management of irreducible IP dislocation of the great toe presenting three new patients who cover several forms: Open and closed dorsal Miki Type 2 dislocation and one chronic neglected plantar dislocation. Cases Report: These three new cases demonstrate different presentations of IP (adolescents or young adults, open or closed, acute or chronic, dorsal, and plantar). Usually, Miki’s Type I is the result of a failed IP dorsal Miki’s 2 dislocation reduction. Closed reduction without traction is not usually sufficient, thus percutaneous reduction with K-wire fixation or open reduction should be employed. Open reduction was required in these cases. A Kirschner wire was used to for temporal immobilization in two of the cases and a buddy strapping securing to the second toe for 3 weeks in the three cases. Conclusions: In dorsal dislocations the reduction must be performed without axial traction and only by pressure in the base of the phalanx. Secondary to the trial of orthopedic reduction or spontaneously, incarceration of the sesamoids bones is the rule (Miki 1). In this situation, percutaneous or open reduction must be performed. Plantar dislocation does not provoque intra-articular sesamoid interposition. This article describes the first reported case of neglected plantar dislocation that required open reduction, similar management adding that the long-term functional prognosis is good. Keywords: IPJ dislocation, great toe, irreducible, Miki classification, dorsal and plantar.

“…It can be accompanied by other foot deformities such as cross toe, hammer toe, at foot and so on [14][15] . The incidence of hallux valgus was reported in literature as 2%-50% [16] with a completely difference. In 1990, the National Institutes of Health calculated that the incidence of hallux valgus was 5.1% [17] .…”

Objective. To study the correlative between the sesamoid bones under the head of the first metatarsal and the development of hallux valgus determined with radiographs.Methods.The measurements were performed on the X-ray of 300 normal feet and 300 cases of hallux valgus. The following parameters were measured: hallux valgus angle(HVA); the first-second intermetatarsal angle(IMA) between the axes of the first and second metatarsal;the length of the second metatarsal（CD）;the position of tibial sesamoid(TSP ) measured the percent formed between the tibial sesamoid and the centreline of the first metatarsal;the position of fibular sesamoid(FSP) measured tangent value between fibular sesamoid bone and lateral cortex of first metatarsal bone ; the absolute distances (AB) from the centre of the tibial sesamoid to the long axis of the second metatarsal, the absolute distances (EF) from the centre of the fibular sesamoid to the long axis of the second metatarsal and the absolute distance (GH) from the centre of the tibial sesamoid to the centre of the fibular sesamoid. Then calculate the ratio of AB to CD (K1), EF to CD (K2) and GH to CD (K3). Results.HVA moderately positively correlates with TSP and moderately negatively correlates with FSP in subjects with HVA ≥ 20°. HVA and FSP are strongly negatively correlated in the hallux valgus group. Conclusion.The dislocation of sesamoid bone under the first metatarsal head is an important pathological factor leading to valgus. HVA is positively correlated with TSP and negatively correlated with FSP.
