Here’s a paragraph describing a “Wrist Joint 3D Reconstruction (Carpal Bones)”:
A Wrist Joint 3D Reconstruction (Carpal Bones) is an advanced imaging technique that leverages CT (computed tomography) scan data to create a detailed three-dimensional model of the wrist, with a specific focus on the eight carpal bones—scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate—while also including the adjacent distal radius and ulna in the context of the joint. This method involves acquiring a series of thin-slice X-ray images as the scanner rotates around the wrist, which are then processed by specialized software to render a rotatable, high-resolution 3D visualization, highlighting the complex geometry and interrelationships of the carpal bones. It is particularly useful for diagnosing intricate fractures (e.g., scaphoid fractures), assessing carpal instability, or planning surgical interventions like fusion or fixation, offering precise insights into bone alignment and joint congruity that plain X-rays might miss. Performed without contrast unless soft tissue detail is needed, this reconstruction provides superior diagnostic clarity, though it involves higher radiation exposure than standard radiographs. With the patient’s wrist positioned neutrally, this technique is invaluable for orthopedic and trauma cases requiring a detailed understanding of carpal bone pathology.
