Case Reports in Orthopedics
|May 29, 2018
Summary
Posttraumatic proximal radioulnar synostosis (PPRUS) is a rare complication of minimally displaced radial neck fractures. This case highlights the potential for PPRUS development even without severe injury or surgery.
Area of Science:
- Orthopedic surgery
- Pediatric orthopedics
- Trauma surgery
Background:
- Posttraumatic proximal radioulnar synostosis (PPRUS) typically follows severe radial head/neck fractures or operative fixation.
- Minimally displaced, nonoperatively treated radial neck fractures rarely lead to PPRUS.
Observation:
- A pediatric case of PPRUS developed after a minimally displaced radial neck fracture.
- The injury was treated nonoperatively and included a concomitant olecranon fracture.
Findings:
- This case suggests PPRUS can occur in rare instances following nonoperative treatment of minimally displaced radial neck fractures.
- The association requires further investigation with more reported cases.
Implications:
- Clinicians should consider the rare possibility of PPRUS in pediatric patients with minimally displaced radial neck fractures and associated elbow injuries.
- Early recognition and consideration of PPRUS are crucial for appropriate management in pediatric elbow trauma.

01:23Radial System Protection
447
Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

01:26Muscles of the Anterior Neck
4.9K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

01:26Arteries of the Head and Neck
3.3K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:19Veins of Head and Neck
5.7K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
