“…Also, it was always thinner than the main EHL tendon. This pattern of origin was consistent with the report of Boyd et al (2006) in that the AT may diverge from either EHL tendon or the muscle belly in adults. However, different from ours, Boyd stated that AT may also arise from several other muscles such as anterior tibial and extensor hallucis brevis muscles.…”

“…On the other hand, Bibbo et al (2004) reported that their findings did not support the hypothesis that the accessory tendon of the first MTPJ plays role in the development of hallux valgus. Tate et al (cited in Bibbo et al, 2004 andBoyd et al, 2006) described the function of AT of EHL muscle as the stabilization of the first MTPJ capsule (by preventing capsular buckling or impingement) upon dorsiflexion of the hallux. Because of the absence of AT in~20% of the specimens and its small size, Bibbo et al (2004) questioned this function of AT.…”

“…Some textbooks (Romanes, 1981) claim that it can be ''occasionally'' found while some others assert that EHL muscle ''usually'' gives AT (Standring et al, 2005). Also, studies on cadavers (Denk et al, 2002;Al-saggaf, 2003;Bibbo et al, 2004;Boyd et al, 2006) have reported several frequencies for these AT, varying between 35 and 81%. Thus, the first aim of this study is to determine the AT frequency of EHL muscle in fetuses.…”

“…It has also been noted that EHL may send tendons to the first metatarsophalangeal joint (MTPJ) capsule. These are also called the extensor hallucis capsularis by Boyd et al (2006). However, there are various data about the incidence of these tendons.…”

There are various data about the incidence of accessory tendons (AT) of extensor hallucis longus (EHL) muscle; however, their function is unknown. This study aimed to determine the incidence and morphometric features of the AT of EHL muscle in fetuses in order to provide more information to discuss its possible function. Forty-five fetuses (26 female and 19 male) were used in this study. Fetuses were grouped as Group A (16-21 weeks), Group B (22-27 weeks), and Group C (28-34 weeks) according to their age. In 23 (51%) out of 45 fetuses, there were AT. These were bilateral in 15 fetuses (65%) and unilateral in eight fetuses (35%). Fifty-two percent of the fetuses in group A, 43% in group B, and 67% in group C had AT. AT were observed in 14 female (54%) and 9 male (47%) fetuses. In all cases, the AT were always diverging to the medial side of the main EHL tendons and attached to the metatarsophalangeal joint capsule distal to the joint space. Significant correlations were observed in this study between EHL and AT widths as well as between EHL width and EHL-AT distance on both sides. The present study is the first to provide morphometric data about the AT of EHL muscle in fetuses which will be of use in understanding their function, particularly in biomechanics of the great toe.

RESUMENEl objeto de éste estudio fue observar detenidamente la anatomía del Extensor Hallucis Longus, Ligamento Capsularis o Tendón Accesorio del músculo Extensor Hallucis Longus; defi nir su su frecuencia de aparición, pues es un músculo que no está presente en todos los pies y suscita controversia en la bibliografía consultada.El Ligamento Capsularis es un ligamento del grupo dorsal del pie, que acompaña al músculo Extensor Hallucis Longus siempre medial a él.Pretendemos demostrar con nuestras disecciones, que es un ligamento más habitual de lo que parece y, dónde está su origen e inserción, así como su función, presentación y ubicación mediante fotografías en pies de cadáver, así como medidas sobre su anchura y características particulares.Para conseguir nuestro objeto de estudio en éste artículo, se diseccionan 50 primeros dedos de cadáver humano, realizando las pertinentes mediciones. Palabras clave: Extensor Hallucis Capsularis, estudio, anatomía, frecuencia, mediciones. ABSTRACTThe purpose of this study was to look closely at the anatomy of the extensor hallucis longus, ligament or tendon capsularis Accessory Extensor hallucis longus muscle; defi ne its occurrence frequency, it is a muscle that is not present in all feet and raises controversy in the reviewed literature. The ligament is a ligament capsularis dorsalis pedis group that accompanies the extensor hallucis longus muscle medial to it forever. We intend to demonstrate by our dissections, a ligament more common than it seems and where is its origin and insertion as well as their function, presentation and location by using photographs of cadaver feet and its width measures and characteristics. To achieve our object of study in this article, fi rst 50 dissected human cadaver fi ngers, making the relevant measurements.

Extensor Hallucis Capsularis: Frequency and Identification on MRI

Abstract: Up to 14% of the population may have an EHC tendon suitable for grafting in reconstructive surgeries, particularly surgeries related to hallux dysfunction. MRI may have a role in the preoperative identification of the EHC.
