Eponymous foot injuries

Eponymythology: The myths behind the history

Eponymythology associated with signs, symptoms, investigation and management of foot injuries. We review related eponyms, the person behind their origin, their relevance today, and modern terminology

Jones Fracture (1902)
Jones-Fracture-5th-Metatarsal 360

Fracture of the proximal diaphysis of the 5th metatarsal, distal to the tuberosity, without joint involvement caused by foot inversion / twisting and repetitive stress. First described by Robert Jones in 1902 after Jones sustained the injury whilst dancing. He published his case report and that of five similar injuries specifically noting that the fracture is caused by ‘indirect violence

Whilst dancing, I trod on the outer side of my foot, my heel at the moment being off the ground. Something gave way midway down my foot, and I at once suspected a rupture of the peroneus longus tendonI hobbled down-stairs to my colleague…to X-ray my foot. This was done, and the fifth metatarsal was found fractured about three-fourths of an inch from its base.

Köhler disease I (1908)
Köhler disease 150

Köhler disease is a rare, self-limiting, avascular necrosis (osteonecrosis) of the navicular bone in children. First described by German radiologist Alban Köhler in 1908.

Note: Adult onset osteonecrosis of the tarsal navicular is known as Müller-Weiss syndrome (MWS) (also Brailsford disease).

Freiberg infraction (1914)
Freiberg infraction 150

Osteochondrosis of the metatarsal heads (typically the 2nd metatarsal head) characterized pathologically by subchondral bone collapse, osteonecrosis, and cartilaginous fissures. Freiberg infraction is more common in women and most commonly manifests during adolescence (aged 10-18 years). Bilateral presentation in 10% of cases. Cause unknown and probably multi-factorial. High-heeled shoes have been implicated as a causative factor.

In 1913, Freiberg presented a paper to the Southern Surgical and Gynecological Association. He reported the cases of six young women presenting with a painful limp and discomfort localized to the second metatarsal, the first patient presenting in 1903. Freiberg employed used the term ‘infraction’ as the diagnosis (archaic term for fracture without displacement implying trauma as the cause).

I felt justified in the diagnosis of infraction of the distal end of the second metatarsal, a condition which I have thus far failed to find described in the literature.

Freiberg 1914

Köhler called out Freiberg for an ‘incomplete‘ description of ‘metatarsal infraction‘ lacking mention of the widening of the joint line; thickening of the shaft of the metatarsal and obliteration of the neck. Process often referred to as Köhler disease II

Calcaneal angles

Böhler angle (1931)

The angle between line from highest point of anterior process to highest point of posterior facet plus line tangential to superior edge of tuberosity; measured on lateral foot x-ray. Normally 20-40°. If < 20° represents a calcaneal fracture (or more specifically a collapse of the posterior facet)

Normally there exists, between the upper contour of the tuberosity of the os calcis and the line uniting the highest point of the anterior process with the highest point of the posterior articular surface, an angle of thirty to thirty-five degrees. This angle I have named face is driven downward; the the “tuber-joint angle“. In fractures of the os calcis this angle becomes smaller, straight, or even reversed

Gissane angle (1946)

Gissane Angle [aka *critical angle; critical angle of Gissane], like the Böhler angle, can be used to help determine the presence of a calcaneus fracture on a radiograph.

The angle is measured on lateral foot radiograph formed by the intersection of the lines drawn along the downward (posterior facet) and the upward (anterior process) slopes of the calcaneal superior surface. Normal range (120-145°).

Joints, lines and amputations

Chopart joint (1792)
Chopart fracture dislocation

The mid-tarsal joint is also known as the Chopart joint. Chopart disarticulated this joint when performing forefoot amputations (Chopart amputation). A Chopart fracture-dislocation involves a midtarsal joint (talonavicular and calcaneocuboid) dislocation with associated fractures.

Chopart’s student, Lafiteau provided the first description of Chopart’s method of partial amputation of the foot and Chopart’s joint in Volume IV of Fourcroy ‘La médecine éclairée par les sciences physiques‘ in 1792. The fracture-dislocation was attributed at a later date.

Lisfranc joint (1815)
Lisfranc joint injury

Lisfranc is eponymously associated with his tarsometatarsal forefoot amputation (Lisfranc amputation). However, Lisfranc was not the first to describe the procedure, with William Hey (1736-1819) first performing the procedure in 1799 and publishing in 1803.

In 1815, Lisfranc described and refined the disarticulation of the forefoot at the tarsometatarsal joint complex which joins the forefoot and midfoot (Lisfranc joint). Lisfranc defined the coup de maître of his disarticulation being the incision of the interosseous ligament (subsequently referred to as the Lisfranc ligament).

The Lisfranc ligament complex includes the dorsal, interosseous, and plantar ligaments which connect C1 (medial cuneiform) to M2 (2nd metatarsal base). Lisfranc injury refers to disruption of the tarsometatarsal joint. Injuries range from sprain (minor diastasis) through to tarsometatarsal fracture-dislocation.

Lisfranc’s description of amputation through the tarsal-metatarsal joints requires several pages to describe it, but it took only 1 minute for him to perform it — not too short a time for the unanesthetized patient

Syme amputation (1831)

Pirogov amputation (1854)

Amputation of the ankle joint in which the posterior process of the calcaneus is retained in the skin flap and opposes the distal cut of the tibia.


Morton metarsalgia (1876)

In 1876 Morton described a series of 15 patients of his own and one of a colleague who all shared the same complaints, which he termed metatarsalgia and which he attributed to an injury to the fourth metatarsophalangeal joint.

  • Morton neuroma – benign, perineural fibrotic lesion of a common digital nerve
  • Morton neuralgia, metatarsalgia (1876)

Note: In 1835, Filippo Civinini of Pistoja (1805-1844) described in the anatomic letter entitled “Su un nervoso gangliare rigonfiamento alla pianta del piede” (“On the neural ganglion swelling of the foot sole“) – the fusiform (gangliare) swelling (rigonfiamento) in the common plantar digital nerve to the third interspace. However there was no clinical description (metarsalgia) involved in this report.

In 2005 Larson wrote:

Review of the historical writings demonstrates that Morton did not describe a painful condition related to a common plantar digital nerve of any web space but rather a painful condition related to the fourth metatarsophalangeal joint. He treated this painful condition by resection of the joint and the nerves, probably on both sides of that joint.
