Bone Mineral Density in the Scaphoid.

: The scaphoid bone is essential for wrist stability and movement. While fractures commonly occur at the scaphoid's waist, those at the proximal pole, though rarer, tend to result in nonunion, potentially linked to variations in bone mineral density (BMD). Previous studies have shown an increase in BMD at the proximal pole in fractured scaphoids, but BMD distribution in intact scaphoids has not been well studied.
