Insights
Obstetric brachial plexus injuries in newborns can cause arm plegia. Magnetic resonance imaging (MRI) is crucial for diagnosing nerve damage and guiding treatment, while radiography assesses shoulder deformities.
Area of Science:
- Pediatric neurology
- Neonatal care
- Musculoskeletal imaging
Background:
- Brachial plexus injuries are a leading cause of neonatal arm plegia.
- Accurate diagnosis of nerve root avulsions and intraspinal lesions is vital for effective treatment strategies.
- Magnetic resonance imaging (MRI) is the preferred non-invasive imaging modality for infant brachial plexus evaluation due to its ability to visualize nerve lesions without radiation.
Observation:
- Conventional radiography plays a role in follow-up assessments of osseous deformities in the glenoid fossa and humeral head.
- This case report details an obstetric brachial plexus injury in a 3-year-old girl.
- The injury was complicated by the development of glenohumeral shoulder deformity.
Findings:
- MRI enables detailed visualization and localization of various nerve lesions within the brachial plexus.
- Radiography can identify and monitor skeletal changes, such as glenoid fossa and humeral head deformities, over time.
- The presented case highlights a complex outcome of neonatal brachial plexus injury.
Implications:
- Early and accurate diagnosis using MRI can significantly impact treatment planning for neonatal brachial plexus injuries.
- Long-term follow-up with radiography is important for managing associated skeletal complications like glenohumeral deformity.
- Understanding these imaging modalities is key to optimizing patient outcomes and managing the long-term effects of brachial plexus injuries.
Abstract:
Brachial plexus injury is the most common cause of plegic arm in neonates. Detection of nerve root avulsions and intraspinal nerve lesions is most valuable for treatment strategy. Magnetic resonance imaging (MRI) is the modality of choice for imaging the brachial plexus in infants as it allows visualization and localization of different types of nerve lesions in a noninvasive way and without radiation exposure. Conventional radiography of the shoulder is of interest in follow-up to assess osseous deformities of the glenoid fossa and humeral head. We report a case of obstetric brachial plexus injury complicated with glenohumeral shoulder deformity in a 3-year-old girl.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
