Case:
A 9-day-old male neonate presented with swelling over his left shoulder and reduced movements of the left upper extremity since birth. Radiographs raised a suspicion of a shoulder dislocation. Ultrasonography confirmed the diagnosis of proximal humeral physeal separation. Magnetic resonance imaging (MRI) revealed edema of the infraclavicular part of the brachial plexus. Conservative management was followed, and the injury remodeled completely at 2 years.
Conclusion:
Neonatal proximal humeral physeal separation poses a diagnostic challenge. Ultrasonography is helpful for diagnosis. MRI is indicated when concurrent brachial plexus birth injury is suspected. Conservative management yields good outcome in the absence of entrapped nerves and tendons.

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...
