Carpal navicular fracture, also known as scaphoid fracture, is a common type of wrist fracture that affects the scaphoid bone in the wrist. Understanding the anatomy, causes, symptoms, diagnosis, and treatment options of this fracture is crucial for proper management and recovery. A reputable source, the American Academy of Orthopedic Surgeons, provides comprehensive information on this topic.
Anatomy of the Carpal Navicular Bone
The carpal navicular bone, also known as the scaphoid bone, is an important component of the wrist’s anatomy. Situated on the proximal row of carpals, this boat-shaped bone has a rounded proximal surface and a flattened distal surface. With dimensions of approximately 3 cm in length and 1.5 cm in width, it provides stability and allows for proper movement of the wrist joint by articulating with neighboring bones like the radius, lunate, and scaphoid.
Ligaments play a pivotal role in maintaining the carpal navicular bone’s stability, enabling various wrist movements. The bone’s blood supply primarily derives from branches of the radial artery. Its significance lies in its ability to transmit forces between the forearm and hand, contributing to wrist joint flexibility and stability.
This bone is susceptible to fractures, often resulting from falls or direct trauma to the wrist. Fractures can cause pain, swelling, and limited mobility of the wrist.
Understanding the anatomy of the carpal navicular bone is crucial for healthcare professionals and individuals seeking knowledge about wrist structure.
It facilitates accurate diagnosis and effective management of injuries, particularly carpal navicular fractures. Medical practitioners can apply this knowledge to provide appropriate treatment and rehabilitation strategies.
