Leland Greene Hawkins (1933 – 1991) was an American orthopedic surgeon.
His research interests were vast, publishing on topics ranging from the use of a Bier block for upper extremity fractures and dislocations to the systemic and local complications of intra-arterial injection of street drugs into the upper extremity.
Hawkins established his eponymous classification system for vertical neck fractures of the talus in 1970. The Hawkins Classification revolutionized management and helped quantify the risk of progression to avascular necrosis

Hawkins Classification of Talus fractures (1970)
Classification system for vertical neck fractures of the talus, the commonest type of talus fracture. High energy injury usually associated with forced dorsiflexion and axial load. Associated with risk of avascular necrosis (AVN)
In 1970, Hawkins described injury patterns and avascular necrosis (AVN) rates in a series of 57 vertical neck fractures of the talus in 55 patients from three different institutions. All 55 patients sustained forced dorsiflexion injuries, similar to the mechanism described as Aviator’s Astragalus by Anderson in 1919. Originally classified into three types (Types I-III)
When faced with the decision of how to manage a vertical fracture of the neck of the talus, the physician must clearly distinguish between two problems. First is a method of satisfactory primary treatment of the fracture, and second, the recognition and management of the avascular necrosis which may follow when the fracture is associated with dislocation of the body.
Canale and Kelly added Type IV in 1978
- Hawkins Type I: Non-displaced talus neck fracture
- Hawkins Type II: Talus neck fracture with subtalar dislocation
- Hawkins Type III: Talus neck fracture with subtalar and tibiotalar dislocation
- Hawkins Type IV: Talus neck fracture with subtalar and tibiotalar and talonavicular dislocation
