Up to 70% of cases of hand Hand The hand constitutes the distal part of the upper limb and provides the fine, precise movements needed in activities of daily living. It consists of 5 metacarpal bones and 14 phalanges, as well as numerous muscles innervated by the median and ulnar nerves. Hand: Anatomy or wrist pain Pain An unpleasant sensation induced by noxious stimuli which are detected by nerve endings of nociceptive neurons. Pain: Types and Pathways can be determined by history alone.
The scaphoid’s blood supply:
The scaphoid’s blood supply is primarily received from the lateral and distal branches of the radial artery via the palmar and dorsal branches. The palmar and dorsal branches provide an “abundant” supply of blood to the middle and distal portions of the
bone

Tearing away of the cortical bone fragment at the location of a strong ligament or tendon attachment. The bone fragment detachment site often occurs near a soft site (e.g., growth plate) at the base where ligaments; tendons; or joint capsules attach.
