Summary
This case study details a rare right triquetral fracture with pisiform subluxation. Surgical fixation led to good functional recovery, highlighting a potential cause of ulnar-sided wrist pain.
Area of Science:
- Orthopedics
- Traumatology
- Radiology
Background:
- Traumatic wrist injuries are common.
- Ulnar-sided wrist pain can have various etiologies.
- Triquetral fractures are less common than other carpal bone fractures.
Observation:
- A 29-year-old male presented with right ulnar-sided wrist pain.
- Initial X-rays revealed a triquetral fracture.
- CT and MRI confirmed the triquetral fracture with associated pisiform subluxation.
Findings:
- The patient had a right triquetral fracture with subluxation of the pisiform and flexor carpi ulnaris.
- Open reduction and lag screw fixation of the triquetrum were performed.
- The patient experienced a good functional recovery post-surgery.
Implications:
- Triquetral fractures with pisotriquetral joint subluxation are uncommon injuries.
- Clinicians should consider this diagnosis in cases of traumatic ulnar-sided wrist pain.
- Prompt diagnosis and appropriate management are crucial for optimal outcomes.

Overview of Flail Chest
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.

01:09Bones of the Upper Limb: Radius
11.6K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

01:15Bones of the Upper Limb: Ulna
11.2K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

01:27Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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...

01:19Bones of the Upper Limb: Humerus
14.6K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
