Abstract:
Intraneural bone was identified on pathologic examination of a neuroma-in-continuity resected for repair of the suprascapular nerve 4 months after a brachial plexus injury. The acute onset of the neurologic deficit, the location of the neuroma within the scapular notch, and the proximity of the neural pathology to a comminuted scapula fracture suggest traumatic penetration of the nerve by a bone fragment. To the authors' knowledge, the observation of bone within a neuroma has not been previously reported.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
