Niels Lauge-Hansen

Niels Lauge-Hansen (1899-1976) was a Danish Radiologist.

Lauge-Hansen (published as Lauge N.) wrote a definitive review of ankle fractures – ‘an analytic historic survey as the basis of new experimental, roentgenologic and clinical investigations‘ 2 years before his classification publication.

Lauge-Hansen’s research was ground-breaking at its time of publication: Injury spectrum provides clinicians with high index of suspicion for easily missed additional injuries on radiographs; radiographic findings allowed surgeons to predict concurrent soft tissue injuries; and provided basis of closed fracture reduction and immobilisation in an era predation modern surgical fixation

Biography

• Born on May 21, 1899 in Jerne, Denmark
• 1925 – Completed medical studies
• 1926-1927 Navy officer with expeditions to Iceland and the Faroe Islands
• Worked primarily at the Central Hospital, Randers, Denmark.
• 1942 – published his thesis ‘Genetisk diagnose og reposition : experimental-chirurgiske og radiografiske Undersøgelser; Repositionsforsøg i Kliniken.’ whilst working at the Bispebjerg Hospital in Copenhagen
• 1943 – Head of the radiology department of the Central Hospital in Randers
• 1948 – published ‘Fractures of the ankle; analytic historic survey as the basis of new experimental, roentgenologic and clinical investigations’, providing a history of ankle fracture management since Hippocrates, forming the basis of his work.
• 1950 – used fresh cadaveric lower limb amputations, fixed with a vice and nails, to observe a spectrum of ankle injuries. These were demonstrated in force produced by hand to the hindfoot, and formed the basis of his publication ‘Fractures of the ankle. II. Combined experimental-surgical and experimental-roentgenologic investigations’.
• 1952 – described how to perform closed ankle fracture reduction, based on reversal of injury mechanism, published in ‘Fractures of the ankle. IV. Clinical use of genetic roentgen diagnosis and genetic reduction’.
• 1954 – applied previous work to describe his radiographic classification and effect of rotational ankle force on interosseous clear space and mortise, publishing ‘Fractures of the ankle. III. Genetic roentgenologic diagnosis of fractures of the ankle’.
• 1959-1961 Worked in Seoul (South Korea), honorary member of the Korean Radiology Association
• Died in 1976.

Medical Eponyms

Lauge-Hansen classification of ankle fractures (1950)

Appreciation of ankle injury mechanism furthers understanding of likely associated ligamentous injury, implications of joint stability and management. The Lauge-Hansen classification requires three radiographic views of the ankle (anteroposterior, mortise and lateral) and is characterised with specific two-word descriptors of the injury mechanism:

• First word: describes the position of the foot at the time of injury (supination or pronation)
• Second word: describes the deforming force direction (abduction, adduction, or external rotation)

Lauge-Hansen’s classification can be difficult to remember and best reviewed in comparison to the simplified Danis-Weber classification. Awareness of the injury mechanism, enhances interpretation and identification of subtle Lauge-Hansen injury stages.

Controversies

Recent research using up to date experimental techniques, has failed to consistently reproduce Lauge-Hansen’s initial findings, questioning the reliability of his classification system. However, the value of his classification when considering concurrent soft tissue injuries, alongside fractures, remains in high regard.
