| shepard fracture | <radiology> Fracture of the lateral tubercle of the posterior process of the talus (12 Dec 1998) |
|---|---|
| Shepherd's fracture | A fracture of the external tubercle (posterior process) of the talus, sometimes mistaken for a displacement of the os trigonum. (05 Mar 2000) |
| sideswipe elbow fracture | <radiology> Comminuted fracture of the distal humerus, due to direct trauma (elbow in car window hits approaching vehicle) (12 Dec 1998) |
| silver-fork fracture | A Colles' fracture of the wrist in which the deformity has the appearance of a fork in profile. (05 Mar 2000) |
| simple fracture | A fracture in which skin is intact at site of fracture. Synonym: simple fracture. (05 Mar 2000) |
| Skillern's fracture | Fracture of distal radius with greenstick fracture of neighboring portion of ulna. (05 Mar 2000) |
| Smith's fracture | <orthopaedics> A fracture of the radius at the wrist that results in volar (palmar) angulation of the distal fracture fragment, opposite the Colles fracture. (27 Sep 1997) |
| spine fracture | A break in the bony cortex of the vertebrae. Spine fractures must be assessed as stable or unstable. Unstable spine fractures pose a risk of spinal cord injury due to abnormal movement at the fracture site. (27 Sep 1997) |
| spiral fracture | A fracture the line of which is helical in the bone. (05 Mar 2000) |
| splintered fracture | A comminuted fracture in which the fragments are long and sharp-pointed. (05 Mar 2000) |
| spontaneous fracture | A fracture occurring without any external injury. (05 Mar 2000) |
| sprain fracture | An avulsion fracture in which a small portion of adjacent bone has been pulled or pushed off. (05 Mar 2000) |
| stable fracture | A fracture that does not tend to displace once it has been reduced and immobilised. (05 Mar 2000) |
| navicular fracture | <orthopaedics> A fracture of the scaphoid (navicular) bone in the wrist. The most common method of injury is a fall on an outstretched hand in an adult. In children, this same type of fall more commonly results in a Colles fracture. (27 Sep 1997) |
| stellate fracture | A fracture in which the lines of break radiate from a central point. (05 Mar 2000) |
