“…En general, existe un patrón común en todos los casos estudiados por los diferentes autores [25][26][27][28] con una variaciones del número de arterias y su área de vascularización. La vascularización arterial de los sesamoideos proviene principalmente de la arteria plantar del primer metatarsiano.…”

“…No obstante las patologías degenerativas y las características de la técnica pueden haber causado un llenado incompleto de los pequeños vasos y haber afectado al aná-lisis del aporte vascular arterial de los huesos sesamoideos del hallux 26 . Otros estudios describen la arteria plantar medial 27 , la arteria plantar del primer metatarsiano 28 o ambas arterias 25 como la principal fuente de vascularización de los huesos sesamoideos, lo cual se corresponde parcialmente con los hallazgos de Rath et al 26 sin embargo, queda por saber si la arteria que sale de la anastomosis es atribuible a la arteria plantar del primer metatarsiano o a la arteria plantar medial. Dado que la arteria plantar del primer metatarsiano es más gruesa que la arteria plantar medial, se considera que la arteria resultante de la anastomosis forma parte de la arteria plantar del primer metatarsiano.…”

Pretterklieber 27,28 , hallazgo que corresponde con los datos obtenidos 26 , aunque hallaron una pobre vascularización arterial distal, lo cual contrasta con las observaciones realizadas 26 . El aporte vascular arterial distal de ambos sesamoideos a través de la rama medial de la arteria plantar del primer metatarsiano no había sido descrito en anteriores estudios.…”

Resumen. Background: Los huesos sesamoideos del primer metatarsiano no son tenidos siempre en consideración a la hora de realizar un diagnóstico, en las patologías que afectan a la región de la cabeza del primer metatarsiano. Ello es debido al escaso conocimiento de todas las entidades patológicas que pueden afectar a los sesamoideos y por la relativa poca incidencia que hasta el momento tienen. Con el aumento de las actividades de práctica deportiva, en concreto del running, cada vez se observan más afectaciones de índole clínica en esta región, relacionadas con este hueso. Métodos: Se realiza una búsqueda bibliográfica en 5 bases de datos (Medline, PubMed, Scopus, Cochrane Library y BUCea). Los términos empleados en la búsqueda fueron: sesamoids, anatomy, biomechanics, sesamoids review y sesamoids pathology. En la búsqueda inicial se tienen en cuenta los artículos con menos de 10 años, ceñidos a humanos y textos de revisión. Resultados: Se seleccionan 24 artículos que incluyen diferentes patologías con sus consiguientes diagnósticos mediante pruebas de imagen y tratamientos, tanto conservadores como quirúrgicos; así como aspectos de la biomecánica de la articulación metatarso-sesamoidea. Conclusión: Los sesamoideos debido a su anatomía, topografía y función pueden estar involucrados en un gran número de patologías; con signos y síntomas generalmente similares entre ellas y que pueden llevar al podólogo clínico a la confusión a la hora de realizar un diagnóstico y un tratamiento acertados. Palabras clave: revisión sobre los sesamoideos; patologías de los sesamoideos y sesamoideos.[en] Sesamoids of the metatarsophalangeal joint of the big toe: a sistematic review Summary. Abstract: The first metatarsal sesamoid bones are not always taken into consideration when making a diagnosis, in pathologies that affect the region of the first metatarsal head. This is due to the insufficient knowledge of all the pathologies that can affect the sesamoids and the relative little incidence that they have. With the increment of sports activities, in particular the running, increasingly affects of the symptoms concerning this region are observed. Methods: A literature search was performed in 5 databases (Medline, PubMed, Scopus, Cochrane Library and BUCEA). The terms included in the search were: sesamoids, anatomy, biomechanics, sesamoids review and sesamoids pathology. In the initial search articles with no more than 10 years, only humans and revision texts are considered. Results: 24 articles were selected and include different pathologies with diagnosis using imaging tests and treatments, both conservative and surgical; as well as aspects from the biomechanics of the metatarsal-sesamoid joint. Conclusion: Sesamoids due of his anatomy, topography and function can be involved in a lot of pathologies; with similar signs and symptoms that can confuse the podiatry when he has to make a correct diagnosis or treatment. Keywords: sesamoids review; sesamoids pathologies and sesamoids.Los autores declaran no tener ningún tipo de interés...

“…Sesamoid fractures may injure the tenuous sesamoid arterial supply, resulting in delayed union, nonunion, or avascular necrosis. 15,56 In one series of 369 stress fractures in athletes, the most common area of delayed union and nonunion was the sesamoids. 52 Nonunion occurs with a large fracture gap, inadequate immobilization, a malaligned fracture, infection, or inadequate blood supply.…”

“…20 Others perform complete excision of the injured sesamoid, but do not advocate removal of both. 15,37,57,59 The [ CASE REPORT ] literature emphasizes maintaining the integrity of FHB tendon insertions into the base of the proximal phalanx with careful reconstruction following sesamoid excision. 5,8,20 Postoperative management of sesamoidectomy ranges from 1 to 3 weeks of non-weight-bearing, followed by ambulation in a rigid shoe for up to 4 weeks, and resumption of activities as tolerated at 6 weeks.…”

insert into the medial and lateral sesamoids, respectively. The intermetatarsal ligament also anchors the lateral sesamoid to the second MTP joint plantar plate.5 A fat-pad cushion and bursa separates the plantar dermis and the sesamoids. 57 In general, the medial sesamoid is larger and longer and the lateral sesamoid is smaller, rounder, and protected by the soft tissue of the first intermetatarsal space. 5,43The sesamoids protect the first metatarsal head by absorbing shock, increasing the FHB and FHL moment arms, and protecting and guiding the FHL passing between them. [3][4][5]53 The estimated resultant force acting across the first metatar-D ancers comprise a unique athletic population. They execute repetitive foot and ankle motions (alternating between extreme plantar flexion and dorsiflexion) with minimal to no supportive footwear, which predisposes them to overuse injuries of the foot and ankle. 10,11,39 Dancers apply a large amount of stress to the hallucal sesamoids when moving onto their toes to grand plié and demi-relevé (ankle plantar flexion and metatarsophalangeal [MTP] joint dorsiflexion), full relevé (ankle and MTP joint plantar flexion), and during eccentric deceleration occurring with jumps and hops. 14,53,58 STUDY DESIGN: Case report.

The aim of this study was to analyze the arterial supply of the sesamoid bones of the hallux. Twenty-two feet from adult cadavers were injected with epoxide resin or an acrylic polymer in methyl methacrylate (Acrifix) and subsequently processed by two slice plastination methods and the enzyme maceration technique. Afterwards, the arterial supply of the sesamoid bones was studied. The first plantar metatarsal artery provided a medial branch to the medial sesamoid bone. The main branch of the first plantar metatarsal artery continued its course distally along the lateral side of the lateral sesamoid and supplied it. The supplying arteries penetrated the sesamoid bones on the proximal, plantar, and distal sides. The analysis and cataloging of the microvascular anatomy of the sesamoids revealed the first plantar metatarsal artery as the main arterial source to the medial and lateral sesamoid bones. In addition, the first plantar metatarsal artery ran along the lateral plantar side of the lateral sesamoid bone, suggesting that this artery is at increased risk during soft-tissue procedures such as hallux valgus surgery.
