Lorenz Böhler (1885 – 1973) was an Austrian Physician and Surgeon.
Pioneer in specialised accident hospitals promoting femoral fracture healing in 50-70% (when the usual success was less than 10%). Advocated immobilisation whilst also maintaining active movement of all other body parts and pioneered specialised accident hospitals promoting femoral fracture healing
Published more than 400 scientific papers and was an honorary member of 33 worldwide associations. His book: ‘Treatment of Fractures’ became a top seller being translated in to eight different languages
Eponymously associated with Böhler angle – a measurement on a lateral foot x-ray to determine calcaneal injuries
- Born 15 January 1885 in Wolfurt, Vorarlberg, Austria
- 1911 – Medical degree, University of Vienna Medical School
- 1914 – Worked at the Mayo Clinic, Rochester, Minnesota. Impressed by the organizational structure of the clinic.

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 reversedBöhler 1931
