Overview

Ulnar bone fracture must be differentiated from other diseases that could affect the bone strength and consequently leads to the bone fracture.

Differentiating Ulnar bone Fracture from other Diseases

In the orthopedic medicine its important to know that the forearm fracture should be evaluated using radiography for both confirming diagnosis and also for evaluating the surrounding tissues. Since there is no "differential" diagnosis list in this regard the main question for the medical doctor and/or orthopedic surgeon is either about what other injuries might be present, or whether the fracture was caused by some underlying abnormality such as osteoporosis causing pathological fracture[1][2]. Additional injuries such as possible olecranon fracture-dislocation; radial head or coronoid fractures or lateral collateral ligament  injury, might be seen in Monteggia fracture. If the mechanism of injury suggests particularly low energy then the Osteoporosis should be considered. The pathological Fractures occurring in a bone with a tumor or Paget's disease) are rare but possible[3].

Also it should be noted that the both bone fractures can be complicated by acute compartment syndrome of the forearm. Signs suggesting compartment syndrome are pain on extension of digits, and marked edema[3].

As another important fact in orthopedic fracture is if both-bone fractures were found in pediatric which is common after accidental trauma, but it may also be the due to the of child abuse; and in these cases a careful attention and evaluation should be considered if a child abuse is suspected[4][5].
