Document Summary

Implement (cause) of blunt force trauma sometimes difficult to tell: baseball bat, rock, metal objects, parts of cars in automobile crash, glass bottle, fractures usually emanate from point of impact this is nice, exceptions: Compression point of tension: fractures take path of least resistance, diastatic fractures. When fracture goes down suture line: weak portion of bone, plastic deformation, bone is deformed from slow forces of blow, falls wrist, colles/smith fracture. Mechanism: colles fall on an extended outstretched hand with straight elbow, dorsal displacement, smith fall on a flexed hand, volar displacement, salter i or ii fracture (3,4,5 are bad) Break between epiphysis and metaphysis: falls arms. Monteggia fracture: ulna with radius displaced at the elbow, fall on pronated outstretched hand with straight elbow, aka night stick injury. Galeazzi fracture: radius with ulna displaced at the wrist, fall on pronated outstretched hand with bent elbow. Inversion or eversion of ankle: abc fractures.
