Since the conquest of the upright position, the foot has gained more importance as an organ that supports both the lower limb and the whole body weight and that allows humans to stand up, walk, run, jump, and climb.

Human evolution determined progressive changes in the skeletal architecture and the soft tissue of the foot to cope with new environmental requirements. From the orangutan to the chimpanzee, from the gorilla to the human, the most important modifications of the skeleton included the progressive reduction of the distal area of the phalanxes with the loss of the grasping function and the enlargement of the proximal bones (astragalus, calcaneum) to obtain a resistant yet flexible structure. See the image below.

The overlying skin and soft tissue, particularly on the foot sole, also changed, acquiring nonshearing and padding properties that made the feet strong and able to support the weight of the body.

Despite these specific and unique features, foot reconstruction has been underestimated for many years, and amputation was considered the treatment of choice for large foot damage until the last century. ^[1]

The history of foot reconstruction began with an attempted morphologic restoration of the shape. The most ancient description is an Egyptian prosthesis found in a pharaoh’s sarcophagus. The first written report on foot injuries is found in Roman war surgery books, in which amputation already is suggested as the elective treatment for serious foot damages.

The introduction of antisepsis and analgesia and the anatomic studies of the foot improved surgical treatment. Foot surgery began to be more accurate and sophisticated, as surgeons sought a proper functional reconstruction rather than a pure morphologic restoration of the shape.

Snyder, in 1965, and Kaplan, in 1969, also highlighted the importance of the sensate reconstruction of the foot sole, particularly for weightbearing (WB) areas.

Numerous local flaps have been described to repair small defects, as follows:

Simple transposition, rotation, and V-Y skin flaps ^[2]

Fasciocutaneous flaps such as the medial plantar flap (“instep flap”), ^[3] lateral calcaneal artery skin flap, ^[4] dorsalis pedis flap, ^[5] medialis pedis flap, ^[6] and the first web space

Muscle flaps such as flexor brevis digitorum, abductor brevis hallucis, abductor brevis minimi dita, flexor brevis hallucis, and extensor brevis digitorum

Lower leg flaps (reverse fascia, sural)

The treatment of large defects remained unresolved until the middle of the 19th century.

In 1854, Hamilton described the cross-leg flap, introducing a new method to repair lower limb defects.

Filatov, in 1917, and Gillies, in 1920, described the tubular pedicled flap, providing another possibility to avoid amputation.

The advent of microsurgery in the 1970s and the description by Ponten in 1981 of myocutaneous and fasciocutaneous flaps started a new era in lower limb and foot surgery.

In 1973, O’Brien (as well as Daniel and Taylor in 1975) described the first free groin flap for reconstruction of the foot.

In 1976, Baudet harvested the free latissimus dorsi. ^[7]

In 1976, Harii first transferred a free gracilis flap, and Robinson introduced the dorsalis pedis fasciocutaneous free flap. ^[8]

In 1978, Chang described the radial fasciocutaneous forearm flap.

In 1980, Dos Santos first transferred a scapular and a parascapular flap. ^[9]

In 1981, Acland introduced the saphenus flap. ^[10]

In 1982, the rectus abdominis muscle flap first was harvested as a free flap by Cunningham and Bunkis. In the same year, Song described the lateral arm flap. ^[11]

In 1984, Lovie described the ulnar flap and Franklin the deltoid, both of which also are suitable for the foot.

A further step in foot reconstruction finally was achieved with the introduction of free osteocutaneous flaps such as the fibula flap ^[12] and the iliac crest. While the iliac crest immediately was used for the foot only, in 1983 Taylor first described the reconstruction of the first metatarsal bone by a free fibula flap. ^[13]

Despite the great variety of flaps, the choice of the most suitable reconstruction remains debated.

Foot diseases may affect normal life significantly, often requiring long care and expensive rehabilitation programs and representing a burden for society.

In the 21st century, the definition of foot reconstruction must take into account tissue reconstruction, function restoration, and cosmetic rehabilitation.

Which considering large foot defects, the following two questions are mandatory:

Can and should this foot be saved?

How can the best functional and morphologic recovery be achieved?

The different reconstructive options are discussed in the following sections. The final choice of the most suitable treatment always relies on the preference of the surgeon, but a correct evaluation of the clinical case must be stressed to obtain a successful result.

Foot ulcers are quite common, even if frequency rates are related strictly to different etiologies.

Because of the higher number of vehicle accidents, mostly involving young active people, defects of the foot sole recently have increased.

Traumas to the foot and ankle account for almost 50% of all traumas affecting the lower limb.

Individuals engaged in certain kinds of physical activities (eg, dancers, football players) also are involved in this high incidence rate.

Sex and age affect the vascular pathologies (eg, arteriopathies, Burger disease [90% in males], Raynaud disease [90% in females], venous congestion) and the dysmetabolic anomalies (eg, diabetes). (For more information on the role of diabetes in foot ulcers, visit Medscape’s Diabetic Microvascular Complications Resource Center.)

Tumors of the foot are rare; melanoma is the most common type, and the foot accounts for 5% of its localization.

Foot defects can be classified according to etiology into 6 main categories.

Traumatic etiology often is correlated to motor vehicle accidents or work accidents. (For more information, visit Medscape’s Trauma Resource Center.) Traumas or injuries may be acute or continued, mild or severe; for example, a mild continued trauma occurs in the foot of dancers. Some occupations require continued use of the foot in a poor mechanical position, thus producing pain and disability; in these patients, the trauma immediately can be repaired only with good circulation.

Trauma also can be intended as a precipitating factor or a factor showing a preexisting situation.

Hidalgo and Shaw divided foot traumas into 3 classes according to dimension and extension of the lesion, as follows ^[14] :

Type I – Small soft tissue loss less than 3 cm²

Type II – Large tissue loss greater than 3 cm² without bone involvement

Type III – Large tissue loss with bone involvement

Vascular etiology may be due mostly to the artery or the vein circulation. An ischemia or a venous stasis determines a necrosis that often leads to an ulcer.

The manifestations of arterial obstruction are more frequent in males and generally are represented by a dystrophy localized on the distal portion of the foot, involving the toes.

Vein stasis generally is rare on the foot, and these ulcers often are localized in malleolar regions or in WB areas, starting with tissue edema and eczema.

Vascular ulcers usually are painful with a higher risk of bacterial infections.

Metabolic pathologies often induce neurovascular alteration to the whole body. Microangiopathy and neuropathy determine a nonpainful craterlike ulceration localized on the plantar side of the foot, especially in the WB areas.

A bacterial infection by anaerobes is fairly common. The most frequent causes are diabetes, alcoholism, phacomatosis, and gout (podagra).

Melanomas, epitheliomas, and sarcomas of the bone or of the soft tissues represent the most common neoplasms that can afflict this region, even if foot tumors are considered rare.

Infective ulcers often are secondary to traumas, vascular deficiencies, or diabetes. All these pathologies can determine a low peripheral oxygenation and promote anaerobes, gram-negative organisms, and saprophyte infections.

Congenital diseases, such as the clubfoot or the bifid spine, are rare. They are associated with deformity of the skeletal and neurologic alterations and easily may determine ulcers on WB areas of the sole.

The foot skeleton represents, as a whole, a sort of arch with the medial side higher than the lateral one, limited proximally by two tubercles of the os calcis and distally by metatarsal heads, as shown below. It is the plantar bend/arch. Since the 18th century, anatomic researchers stated that the lateral arch is represented by the os calcis proximally, the cuboid bone distally, and from the last 2 metatarsi (IV and V). The medial arch, higher than the lateral, is formed by the os calcis proximally and by the astragalus distally.

The structure of the foot bones allows some vector lines to be drawn. The direction of the shafts, shown in the first image below, shows that tension planes and pressure planes share the same direction. Shafts demonstrate the 2 arches theory; these follow the direction of the arches inside the bones, shown in the second image below. During the development of human locomotion, the lateral arch acquired the task of supporting the weight in the standing position, rather than the medial arch, which is involved particularly during the walking cycle.

This unique weight distribution has led to the definition of a “metatarsal formula” for the weight pressure distribution. This formula shows that most of the pressure is supported by the fourth and fifth metatarsi (I less than II less than III less than IV equals V) during the erect and bipodalic station that makes a quadrilateral and thus firmly supports the area and from the first metatarsus (I greater than II equals III equals IV equals V) in the monopodalic station that forms a triangular and thus unsteady area.

Recent studies on the plantar pressure distribution with a baropodometer are introducing a new theory on static and dynamic foot movements, suggesting a more important role of the heads of central metatarsal bones, thus changing the metatarsal formula (I less than II equals III equals IV greater than V). This new theory shows that the first and fifth metatarsal bones are used only to avoid lateral and/or medial falls, particularly during monopodalic station (walking cycle).

According to the authors’ experience, foot defects can be classified clinically with 4 parameters: extension, depth, localization, and etiology.

Particular attention must be paid to the condition of the surrounding tissue and to neurovascular involvement.

Extension – Tissue loss is divided into 2 categories with a different surgical approach, as follows:

Small tissue defects less than 3 cm²

Large tissue defects greater than 3 cm²

Depth

Skin

Subcutaneous and aponeurosis systems

Muscle

Bone

Localization

Anatomic areas (dorsum, medial, lateral side, sole, heel, toes)

Baropodometric areas (WB or nonweightbearing [NWB])

Etiology – Clinical presentation differs according to the causative agent, as follows:

Traumatic ulcers – Irregular shape and margins; possible necrosis for vascular impairment from trauma; normal surrounding tissue; painful; every localization

Vascular ulcers – Regular shape (round) and margin for artery impairment and irregular shape and hypertrophic margins for vein, both with damaged surrounding tissue; different localization such as dorsum of the foot or fingers; usually painful

Diabetic ulcers – Irregular shape; numerous, callous margins; large damage in the depth and in the surrounding tissue; not painful; more frequent in WB areas

A new classification based on anatomy and categorized by soft tissue (ST) defects and bone tissue (BT) damage can be created to summarize clinical features and standardize the treatment. (ST types may also be on WB or NWB areas.)

Type ST-0 – No tissue damage

Type ST-I (calcaneus, dorsal, plantar) – Small tissue defect 1-3 cm²

Type ST-II (calcaneus, dorsal, plantar) – Large tissue defect greater than 3 cm²

Type BT-0 – No bone damage

Type BT-P – Phalanges defect 1-5

Type BT-M – Metatarsal defect 1-5

Type BT-T – Tarsal defect

Type BT-C – Calcaneal defect

Indications for medical treatment are as follows:

ST-I – Small (< 3 cm²) and limited (skin and subcutaneous) soft tissue loss

Vascular etiology

Metabolic etiology

Infections

Indications for surgical treatment are as follows:

ST-I – Small (< 3 cm²) and limited (skin and subcutaneous) soft tissue loss

Traumatic etiology

Neoplastic etiology

ST-I – Small (< 3 cm²) involving aponeurosis or muscular layers or even more superficial but resistant to medical therapy

By local skin flaps

By skin grafts

ST-II – Limited (skin and subcutaneous) defects greater than 3 cm² of nonweightbearing (NWB) areas

By local skin flaps

By skin grafts

ST-II – Defects of the foot greater than 3 cm² of weightbearing (WB) areas

By free flaps

BT-M1, BT-M5, BT-C – Bone loss of WB areas

By free flaps

The foot generally is divided into 4 regions, which are the ankle, sole, dorsum, and toes.

The skin of the foot, except for the sole, is similar to skin in other regions of the body. The epidermis is thin in the newborn but becomes thicker as a reaction to weight pressure. Hair and sebaceous glands are present only in the dorsum. Eccrine glands are diffused in the sole.

The subcutaneous fat is poorly present in the dorsum but is very thick and granular in the sole, where it is divided by the retinacula. The retinacula are connective fibers between the dermis and the plantar fascia that build a sort of “shock absorber” for the standing position or during movements.

The foot sole consists of 4 layers, which are skin, subcutaneous fat, plantar fascia, and muscles.

The plantar fascia is a strong connective tissue stretched between the inner tubercle of the calcaneum and 5 metatarsal heads. Numerous septi departing from this fascia divide foot muscles into 3 compartments. Muscles for the fifth toe are in the medial compartment, for the big toe in the lateral compartment, and for all the other toes in the central compartment.

Foot muscles also are divided by the skeleton into the dorsal side, with extensor brevis digitorum medial and the extensor hallucis laterally, and the plantar side, which is divided into 4 layers. The first layer, the most superficial, is composed of the abductor hallucis, abductor minimi digiti, and flexor brevis digitorum. The second layer is composed of the flexor accessorius and by the lumbricales. The third layer is composed of the flexor brevis hallucis, the flexor brevis minimi digiti, the adductor obliquus hallucis, and the adductor transversus hallucis. The fourth layer, which is the deepest, is composed of the dorsal and plantar interossei.

The skeleton of the foot is composed of 26 bones surrounded by many ligaments to obtain a strong structure. These bones are divided into 3 groups.

The first is the ankle, composed of 7 bones: the rearfoot (astragalus upper and calcaneum lower) and the medial foot (cuboid laterally, navicular medially and internal, middle and external cuneiform distally).

The second group is the metatarsus, composed of 5 metatarsal bones.

The third group is the phalanges, of which 5 are present, composed of 14 bones (3 bones for each phalangis and 2 for the first phalangis).

Apart from these main bones, the sesamoid bones help improve function and are often found as variants of the accessory bones. For more information about the skeletal anatomy, see Foot Bone Anatomy.

The vascularization of the foot can be divided into 3 axes, the anterior tibial pedicle, the posterior tibial pedicle, and the peroneal one. The anterior tibial artery distributes to the dorsal side of the ankle, becoming the dorsalis pedis artery until the back part of the first web space, where it divides into two branches, the dorsalis hallucis and communicating. The other two branches are the tarsal artery upon the navicular bone and the metatarsal artery over the bases of metatarsal bone, where it anastomoses with the tarsal and the external plantar arteries.

This vessel gives off 3 branches. The interosseus arteries receive anastomoses by the perforating branches of the plantar arch; in the cleft between the toes, it divides into 2 dorsal collateral branches from the digital arteries.

The posterior tibial artery passes between the inner ankle and the heel. It divides into 2 branches: the internal plantar artery and the external plantar artery. Numerous calcaneal branches depart behind the Achilles tendon. The internal plantar artery passes forward along the inner side of the foot and the big toe. The external plantar artery passes obliquely to the base of the fifth metatarsal bone; it then turns obliquely inward to the internal between the bases of the first and second metatarsal bones, where it anastomoses with the communicating branch from the dorsalis pedis artery, thus completing the plantar arch. It gives off digital branches.

The third axis, due to the peroneal artery, gives off branches to the posterior side of the ankle and calcaneum.

The veins of the foot are superficial and deep. Two superficial veins are present: the internal, or long, saphenous vein and the external, or short, saphenous vein. They start from a venous arch localized in the dorsum of the foot with a convexity directed forward that receives numerous veins from the dorsum of the toes and the foot. The long saphenous vein passes in front of the inner malleolus, and the short saphenous vein ascends behind the outer malleolus.

Usually 2 deep veins, called venae comitantes, accompany the arteries and their branches. The anterior tibial veins are formed by a continuation upward of the venae comites of the dorsal pedis artery. The valves of these veins are numerous.

Lymphatic vessels are superficial and deep. They superficially accompany the saphenous veins, the deep anterior tibial, the posterior tibial, and the peroneal vessels.

The innervation of the foot comes from the saphenous nerve (L2-L3-L4) and from the sciatic nerve (L4-L5-S1-S2-S3) with its branches (the anterior tibial nerve, the external saphenous nerve, and the musculocutaneous nerve).

The anterior tibial nerve accompanies the dorsalis pedis artery, gives off a branch to the extensor brevis digitorum and extensor brevis hallucis, and gives off a cutaneous branch for the superficial area between the first and the second toes. The musculocutaneous nerve supplies the integument of the dorsum of the foot (big toe internal, second toe external, third toe). The external saphenous nerve completes the lateral cutaneous innervation of the foot.

The posterior tibial nerve accompanies the homonymous artery and gives off a sensitive branch for the internal and inferior areas of the calcaneum before dividing itself into the external and internal plantar nerves.

The internal plantar nerve gives off cutaneous branches for the sole and digital branches for the first, second, third, and internal one half of the fourth toe, and it gives off muscular branches for the abductor hallucis, flexor brevis digitorum, flexor brevis hallucis, and the first and second lumbricales. The external plantar nerve completes the innervation of the sole and is distributed to the little toe and lateral one half of the fourth toe.

Muscular branches are for flexor brevis minimi digiti, all interosseus muscles, lumbricales, adductor obliquus hallucis, adductor transversus hallucis, abductor minimi digiti, and accessorius. The internal saphenous nerve gives off cutaneous branches for the medial side of the foot.

Contraindications to medical treatment include neoplastic etiology.

Contraindications to surgical treatment by local flaps or grafts include macroscopic bacterial contamination and necrosis, which require a 2-step procedure: first, clean the foot; second, reconstruct.

Contraindications to surgical treatment by free flaps include severe trauma involving 2 of 3 vascular pedicles of the leg, severe vascular or dysmetabolic disease, poor general conditions, and severe smoking habit.
