Antes de explicar que tipo de ejercicio es y para que sirve, vamos a hacer una breve introducción de que es el CORE.

<<Este término hace referencia a una coordinación entre:

• Sistema muscular (elementos activos).
• Sistemas pasivos como son los ligamentos, articulaciones y huesos
• Sistema propioceptivo, es decir, de consciencia y percepción de en que posición del espacio se encuentran los segmentos corporales y de la capacidad de responder a un estímulo externo de forma controlada (por ejemplo cuando se nos va el pie hacía fuera y somos capaces de responder para no hacernos un esguince).

Como hemos podido comprobar, el CORE es muy importante para la salud general del pie y el tobillo. Si nos han operado, se dañan los receptores y los huesos también se ven afectados, por lo que es imprescindible que fortalezcamos esta estructura.

Si somos diabéticos y estamos perdiendo la sensibilidad del pie y se ve afectado, necesitamos prevenir futuras lesiones; si no hacemos ejercicio y los músculos del pie se ven afectados, entramos en una situación de riesgo que favorece las lesiones, etc.

A nosotros en la clínica Vitruvio, nos parece primordial que los pacientes entiendan el por qué de todos los aspectos relacionados con su salud. Por esta razón, solemos poner este ejemplo sencillo que explica que es el “short foot”.

Todo el mundo entiende cuando le dicen: ”pon la espalda recta, que te va a salir chepa”, pero nadie entiende “pon el pie recto” y esto es lo que sería el short foot es una forma de fortalecer todos los músculos y tendones que nos ayudan a poner el pie en su posición correcta por lo que nos sirve tanto para prevenir como para tratar múltiples patologías y dolores y, lo más importante, que es un ejercicio funcional, es decir, el pie trabaja muy parecido a cómo trabaja al andar o mantenernos de pie igual que los ejercicios de planchas para los abdominales.

¿CÓMO PODEMOS HACER ESTE EJERCICIO?

Para pacientes que no son deportistas, recomendamos realizar el ejercio manteniendo la posición mientras que nos lavamos los dientes por tandas de X segundos, es decir, 10 seg e ir subiendo de 5 en 5 seg si vemos que no nos cuesta.

En deportistas lo ideal es que se introduzca en sus actividades de la vida diaria, es decir, que sepan la posición correcta del pie y lo apliquen a la hora de hacer un sentadilla por ejemplo o a la hora de hacer saltos, etc.

Para los más metódicos, se puede realizar 3 series de entre 6 y 10 repeticiones manteniendo la posición correcta del pie unos 6 segundos cada una.

Lo ideal es hacer todos estos ejercicios a la “pata coja”

Morton’s neuroma is an entrapment neuropathy of the third common plantar digital nerve, caused by the deep transverse metatarsal ligament (DTML).
Minimally invasive or percutaneous surgery is a very common procedure, but surgical effectivity of this technique remains controversial. The goal of our study was to prove the effectiveness and safety of a new ultrasound-guided technique for DTMLrelease in a cadaver model.

Materials, Methods, and Results: The DTML was visualized in 10 fresh frozen donated body to science-feet (eight male and two females, five left and five right) using an US device (GE Logic R7; 13 MHz linear probe, Madrid, Spain).

Consecutively, minimally invasive ultrasound-guided surgery was performed. Exclusion criteria of the donated bodies to science were previous history of forefoot surgery and space occupying mass lesions. The complete release of the ligament was achieved in all specimens without damage of any important anatomical structures as proven by anatomical dissection.

** Conclusions: The results of this study indicate that our novel approach of an ultrasound-guided release of the DTML is safer and more effective compared to blind techniques. The DTML could reliably be visualized and securely cut through a dorsal, minimally invasive surgical incision of only 2 mm.

>> INTRODUCTION

Morton’s neuroma (MN) was initially mentioned by Civinini in 1835
(Civinini, 1835).

Later—in 1845—Durlacher described the clinical Gabriel Camunas Nieves and Alejandro Fernández-Gibello contributed equally to this work. symptoms and finally in 1876, Thomas George Morton reported the Received: 21 July 2020 Revised: 28 September 2020 Accepted: 1 October 2020 DOI: 10.1002/ca.23692

Clinical Anatomy. 2020;1–7. wileyonlinelibrary.com/journal/ca 1 condition of metatarsalgia as a “peculiar and painful affliction of the fourth metatarsophalangeal articulation”  (Adams, 2010; Civinini, 1835; Di Caprio, Meringolo, Shehab Eddine, & Ponziani, 2018; Durlacher, 1845; Matthews, Hurn, Harding, Henry, & Ware, 2019; Morton, 1876).

MN is not a true neoplastic or proliferative process due to its degenerative pathogenesis with histologically verified demyelination of the nerve fibers, fibrosis of the epi- and endoneurium including the so-called Renaut bodies and densely packed whorls of collagen (Adams, 2010).

Many different theories have been postulated to explain the pathogenesis of MN: repeated microtrauma, chronic traction damages, ischemia of the vasa nervorum, a secondary neurofibrosis after inflammatory intermetatarsal bursitis, increased tension in the foot fasciae and, currently widely accepted, an entrapment neuropathy of the third common plantar digital nerve due to an external compression by the deep transverse metatarsal ligament (DTML)
(Stecco et al., 2015; Valisena, Petri, & Ferrero, 2018).

The incidence of chronic entrapment of a common plantar digital nerve is highest in the third intermetatarsal space (i.e., MN), followed by the second space (i.e., Hauser’s neuroma) and least at both, the fourth (i.e., Iselin’s neuroma) and the first space (i.e, Heuter’s neuroma)

(Larson, Barrett, Battiston, Maloney, & Dellon, 2005; Matthews et al., 2019). The female-to-male ratio reported in the literature is 4:1
(Di Caprio et al., 2018). Clinically, patients complain of burning metatarsal pain, often radiating to the toes, and sharp shooting sensations of pain (Di Caprio et al., 2018). Pain is exacerbating when the patient
wears tight shoes or high heels, which leads to a narrow intermetatarsal space, augmented plantar metatarsal ground reaction forces and lastly to an extension of the metatarsophalangeal joint— resulting in compression of the common digital plantar nerve beneath the DTML (Di Caprio et al., 2018).

Apart from clinical diagnosis considered as the gold standard, imaging techniques such as ultrasonography (US) or MRI, were cited for detection of a common plantar digital nerve entrapment. Notably, both MRI and US were rated just equally or even less accurate compared to physical examination (Claassen et al., 2014; Di Caprio et al., 2018; Lee et al., 2007; Sharp, Wade,
Hennessy, & Saxby, 2003). Nevertheless, especially in skilled hands, US has its own and well documented advantages (Pastides, El-Sallakh, & Charalambides, 2012).

We are, to the best of our knowledge, not aware of studies dealing with US-visualization of the DTML as a basis for minimally invasive decompression surgery in the given context. Therefore, the goal of our study was to develop a new, landmark-based, ultrasoundguided, minimally invasive technique for a DTML-release for Morton’s neuroma.

1.1 | Normal anatomy of the DTML and its topographical relationships

The individually varying distance between the metatarsals is defined by two mostly transverse structures: the deep dorsal intermetatarsal fascia and the DTML (Figures 1 and 5). The latter in particular, helps to avoid too much splaying of the toes (Figures 1 and 5). The DTML is a mostly transverse band embedded in the plantar metatarsophalangeal joint capsule complex, which is composed of four parts connecting all heads of the metatarsal bones and heads of phalanges to form a functional unit.

Dorsally to the DTML a synovial bursa (the so-called “intermetatarso phalangeal bursa”) can be found that protects both metatarsal heads and the tendons of the interosseous muscles from fraying. Sandwiched between the ligament and the plantar fat body (also called “plantar monticuli”) (Kelikian & Sarrafian, 2011), the common plantar neurovascular bundle can be found adjacent to the third plantar plate, while the tendon of the lumbrical muscle is situated more fibularly close to the fourth plantar plate (Stecco et al., 2015) (Figures 1 and 3a).

>> MATERIALS AND METHODS

All consecutive steps described below were performed in 10 fresh frozen feet of eight male and two female cadavers (five right and five left, aged between 65 and 80 years), which belong to the Body Donation Centre.

The individuals had given their written informed consent for their use for scientific purpose prior to death. According to National Law, scientific institutions (in general Institutes, Departments or Divisions of Medical Universities) are entitled to receive the body after death mainly by means of a specific legacy, which is a special form of last
will and testament.

No bequests are accepted without the donor having registered their legacy and been given appropriate information upon which to make a decision based upon written informed consent (policy of ethics); therefore, an ethics committee approval was not necessary (Konschake & Brenner, 2014; McHanwell et al., 2020).
The exclusion criteria for this study were previous history of forefoot surgery and space occupying mass lesions.

Equipment used: high-frequency US-system with a 13 MHz linear probe (General Electric Logic R7; 8 mHz, Madrid, Spain), a scalpel for minimally invasive surgery with a beaver 64 blade, and a buttoned probe.

2.1 | “Step-by step” approach

After US-visualization of the DTML (Step I), we performed a landmark-based, minimally invasive US-guided surgical approach in all specimens (Step II), followed by anatomical dissections of the third intermetatarsal space (Step III) evaluating the effectiveness and safety of surgical release of the DTML.

2.1.1 | Step I: Anesthesia, US-identification of the DTML and skin incision

To avoid alteration of the clarity of the US image due to preprocedural local anesthesia bolus in such small probe girth we recommend a
2 NIEVES ET AL. proximal anesthesia procedure (e.g., US-guided ankle blocks) or at tarsal-metatarsal joint level.

The US probe was positioned at the sole, between the heads of the respective metatarsals and in the long axis of the third intermetatarsal space for visualization of the DTML. As a control, the US probe was turned 90
to identify the ligament spanning between the
plantar plates, and the position of the neurovascular bundle in its typical location (Figures 1 and 3a).

To ease identification of the DTML in the longitudinal view through a marked movement, a buttoned probe was simultaneously placed at the dorsum of foot between the metatarsal heads and pushed plantarly (Nieto García, 2016) (Figures 1–3b).

The dorsal longitudinal skin incision was done with a scalpel close to the surgical neck of the fourth metatarsal head (the “surgical neck” being a constriction straight proximal to the head of the metatarsal bone, which is frequently seat of fractures).

2.1.2 | Step II: Surgical procedure under US-guidance

After clear identification of DTML, we introduced the blade through the skin incision and advanced it gently toward the DTML under direct US visualization in plane. The ligament was then transected from proximal to distal. In order to verify the complete release of the DTML, the buttoned probe was introduced again, and its tip moved from proximal to distal.

In case of incomplete transection (especially its most distal fibers), the step was repeated. Prior to anatomical dissection, a retractor was inserted dorsally by enlargement of the initial incision in order to verify a widening of the intermetatarsal space under fluoroscopy (Figure 4).

2.1.3 | Step III: Anatomical dissection

An anatomical dissection of all 10 ft was finally made to verify a complete release of the DTML and to proof if no adjacent anatomical structures were injured, respectively: extensor expansion, interosseous.

>> RESULTS

In all 10 ft, the DTML was successfully identified with US in two
planes. (Figure 3a,b). With the transverse view, most important structures in the vicinity (i.e., the neurovascular bundle and plantar plates) were seen clearly (Figure 3a).

The US-appearance of the DTML was similar to the well known characteristics of a true ligament elsewhere in the locomotor apparatus: compared to sharply delineated hyperechoic borders (“white”) the substance of the rest of the ligament muscles, lumbrical muscle, the collateral ligaments, plantar plate, vessels and nerves.

For that, the widened incision for placing the first retractor as mentioned above, a further extension was done longitudinally, and another retractor inserted. Fat and connective tissue were removed carefully until we could visualize all important structures and the complete release of the DTML, respectively (Figures 1 and 5).

>> DISCUSSION:

In the current anatomical study, we describe a new, landmark-based minimally invasive ultrasound-guided surgical release of the DTML. The latter accounts for the majority of cases with compression of the third common digital nerve within its respective intermetatarsal space.

> CONCLUSSION:

Our new ultrasound-guided, minimally invasive surgical approach for
treatment of Morton’s neuroma seems to be a safer and more effective technique in the release of the DTML as compared to previously reported blind techniques. The DTML shows the same and constant US-features as any other true ligament in the human body. This enables its reliable visualization, which is fundamental to a safe, US-guided transection that avoids injury to adjacent anatomical structures.

Los pacientes tienen lesiones por sobrecarga mecánica

En este artículo vamos a hablar de las lesiones por sobrecarga mecánica y excluiremos aquellas patologías que se hayan producido por una lesión traumática como un esguince, fractura, etc. Nos centraremos en lesiones por sobrecarga mecánica.

1.Lesiones por sobrecarga mecánica- Dolor en la zona o cara medial del tobillo.

Normalmente los pacientes que presentan dolor en esta zona tienden a tener pies más aplanados, es decir, con menos arco. La patología más frecuente que se puede tener es la tendinopatía de alguno de los tendones que cruzan en esa zona (tibial posterior, flexor largo de los dedos y flexor largo del dedo gordo).

En casos en los que los pacientes tienen lesiones por sobrecarga mecánica o un dolor más urente, quemante o que pueda dolerles en reposo o de forma nocturna, podremos sospechar de alguna lesión del nervio tibial (síndrome del túnel del tarso).

2. Dolor en la zona del metatarso (metatarsalgia).

Los pacientes suelen sentir dolores o molestias que, en ocasiones, inclusive llegan a la zona de los dedos y que se acentúa al caminar o al usar un mal calzado (calzado demasiado plano, con demasiado tacón o que sea muy estrecho en la zona delantera).

Las lesiones por sobrecarga mecánica más frecuentes que nos solemos encontrar son: lesiones de la placa plantar (suponen cerca del 40% de todas las metatarsalgias), neuromas, siendo el de Morton el más frecuente, bursitis intermetatarsales ¡ojo en pacientes con patología reumática o antecedentes familiares de ello! y puntos gatillo o sobrecargas musculares de la musculatura intrínseca del antepié.

3. Lesiones por sobrecarga mecánica- Dolor en el talón o talalgias.

Aquí se encuentra la joya de la corona de las patologías del pie. Es una lesión que va a sufrir el 10% de la población adulta alguna vez en su vida. La causa más frecuente es que el paciente presente una fasciopatía plantar. Aquí es de vital importancia abordar que la palabra «fascitis plantar» (sufijo itis= inflamación) es errónea o incorrecta ya que se ha visto que es un problema degenerativo y no inflamatorio. Por eso utilizamos el término genérico fasciopatía, que engloba tanto las fasciosis (-osis= degenerativo), como las roturas que son más frecuentes de lo que pensamos. Se ha visto que casi el 30% de los pacientes con fasciosis crónica tienen algún tipo de rotura.

Como dato relevante a tener en cuenta, los pacientes que sufren lesiones por sobrecarga mecánica, como es un dolor que no mejora con tratamiento, que llevan mucho tiempo con ello, que tienen sensación que les quema o arde, pueden presentar asociado “como extra” un atrapamiento nervioso que cree un síndrome del túnel del tarso. Solo el atrapamiento de la rama de Baxter se da en un 20% de las fasciopatías crónicas.

4. Dolor en la zona del tendón de aquiles.

Los pacientes suelen notarse una zona engrosada en el tendón que es dolorosa cuando lo palpan. Las zonas más frecuentes pueden ser las que están pegadas al hueso o las que están en la parte media del tendón y las diferenciamos en tendinopatías de tercio medio o entesopatías o tendinopatías insercionales.

Debemos saber que son diferentes, siendo unas más pesadas de curar que otras. En estos casos, debemos saber con qué tipo de tendipatía nos estamos enfrentando. Después debemos realizar una ecografía para ver como se encuentra el tendón. Son patologías muy tediosas de tratar y como todas las tendinopatías, necesitan de mucha colaboración por el paciente, ya que el tendón se cura con carga progresiva, es decir, con ejercicio.

5. Dolor en la zona o cara lateral del tobillo.

Salvaguardando como hemos mencionado antes los esguinces de tobillo, las patologías más frecuentes que nos encontraremos son las tendinopatías de los peroneos. Se trata de sobrecargas musculares de los mismos o procesos de inestabilidad o subluxaciones de los peroneos. Como patología ligeramente más grave que nos podemos encontrar es la rotura longitudinal o en Split del peroneo lateral corto.

6. Dolor en el dorso del pie.

Son dolores menos frecuentes y se tienden a dar en pacientes con pies muy cavos (con mucho arco) o pacientes con procesos artrósicos o degenerativos (pacientes mayores).

Los más frecuente que vemos en consulta son tendinopatías (tibial anterior o extensor común de los dedos) y procesos inflamatorios de las articulaciones del dorso del pie, es decir, artrosinovitis.

Como disfunción en pacientes que se le sobrecargan o tienen lesiones por sobrecarga mecánica también la zona anterior de la tibia, nos podemos encontrar puntos gatillo de la musculatura que dan dolor referido a la zona del dorso del pie.
