Shepherd fracture

Description

Sherpherd fracture: Posterior talar process fracture with injury to the lateral tubercle caused by inversion or extreme equinus. Otherwise known as fracture of the lateral tubercle of the posterior process of the talus

  • Fracture usually seen on lateral XR, however sensitivity only 78%. In cases of significant trauma and suspicion CT should be considered.
  • Complications: include chronic pain, arthrosis, and occasionally avascular necrosis
  • Treatment: immobilization, although rarely delayed excision of the fragments may be necessary

History

1882 – Described by FJ Shepherd, initially as a single dissection and later as a series of three such fractures

Controversies

Shepherd fracture may be mistaken for an os trigonum (secondary ossification center accessory ossicle) which lies posterior to the lateral tubercle and which is a normal finding. The os trigonum is usually round/oval with smooth well corticated edges as opposed to the sharply marginated non-corticated irregular outline of a fracture

Note: **Cedell fracture – posterior talar process fracture with injury to the medial tubercle caused by forced dorsiflexion and pronation
