“…They can be found in the feet of children diagnosed with multiple exostoses. Solitary osteochondromas of the foot are rare and only sporadic cases are described, affecting the calcaneum, talus, metatarsals, and phalanges [ 1 , 2 , 3 , 4 , 5 ].…”
Introduction: Solitary osteochondromas are extremely rare in the bones of the foot. In the growing skeleton, few cases affecting the metatarsals and the talus have been reported. At present, there have been no reports of osteochondromas affecting the cuneiforms.
Case Report: We report the case of a 13-year-old male patient. He presented with marked prominences in the plantar surface of his left foot and pain while participating in sporting activities. Radiological examination with X-rays, computed tomography (CT) scan, and magnetic resonance imaging revealed two solitary osteochondromas growing from the medial cuneiform and the head of the 1st metatarsal. The patient was treated surgically by excision of the osteochondromas. Histological examination confirmed the diagnosis of osteochondromas. He had an uneventful recovery and returned to his sporting activities.
Conclusion: Solitary osteochondroma can present in the cuneiform and metatarsal of a growing adolescent. CT scan is useful for the accurate diagnosis and surgical removal of the tumor.

“…They are usually found near the physes of long bones, and rarely in the foot and ankle. 3 In the general population, tumors in the foot and ankle are exceedingly rare, representing only 3% of osseus neoplasms. 5 In the metatarsals, the most common histopathologic diagnoses are giant cell tumors, followed by aneurysmal bone cysts, then chondroblastomas and osteosarcomas.…”
An 11-year-old male presented with a mass on the plantar aspect of his right foot initially noted two months prior. The mass was large, firm, and non-tender and was the only presenting symptom. Exam revealed cavovarus foot deformity and altered gait with increased weight bearing on the lateral border of the foot. Work-up revealed a solitary osteochondroma of the plantar aspect of the second metatarsal, which was resected via a dorsal approach. Conclusion: Osteochondromas are benign tumors which can present as solitary lesions and are rarely found in the foot. We present the first case in the literature of a solitary osteochondroma arising from the plantar aspect of the second metatarsal, successfully excised via a dorsal approach.
“…The sesamoid bones on the rst metatarsal head are an important part of the structure and function of the forefoot .It plays an important role in regulating pressure,reducing friction and changing the direction of muscle traction [1][2][3][4] .Whether the sesamoid bones dislocation is corrected or not is an important index about evaluating the curaive effect of valgus correction [5][6][7][8] . Many things are puzzling at the moment, there are a few reports about the quantitative index of the normal position of the sesanoid bones on the rst metatarsal head and clinical cases about the relationship between sesamoid dislocation and hallux valgus.The image research is blank in the aspects of the sesamoid bones at present.…”
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
