Do you want to know about antemortem fractures in advanced stage of decomposition like skeletonization or mummification.????
Because we can easily recognize antemortem fractures in early stages of decomposition.
However, in advanced stage of decomposition we have to take note of the blood adhered to the fracture ends that are difficult to get rid off by washing.
Similarly stages of healing of bone fractures can also ascertain the antemortem nature of fractures
Dear Manoj: As Dr Herbstein said, decomposition is a variable process, but in early stages you can find the haematoma around the fracture, do not forget that the bleeding from the bone is evident especially in large one.(femur-tibia-humerus)
It's difficult to get all those findings mentioned like extravasation of blood, callus formation in the condition you have stated. If the fracture is produced immediately before death there will be no callus formation and as the body is decomposed, there will be difficult to get blood at the fracture site. The only thing we can do with the fracture in decomposed body is to suspect the fracture of antemortem origin with circumstantial evidence till the contrary is proved through proper investigation. It's similar to the adult dead body which is considered being murder till the contrary is proved through proper investigation...................
This really depends on whether we are looking at an anthropological case or pathological case. In both instances, the 'vitality' of the wound is pivotal. However, the features you are looking for depend on the state of decomposition.
Indeed, relatively intact bodies may show signs of bleeding or an inflammatory reaction.
In more decomposed (skeletonized) remains, the microscopic analysis of the fracture end may provide clues, but only if the posttraumatic survival time is long enough for changes to the bone tissue at the fracture end (e.g. Howships lacunae).
Below you can find a link to a book which, although primarily for child abuse, has a good generic chapter on trauma dating:
