The phalanges are disproportionately short and excessively rigid, resistant to flexion, frequently encountered in cases of hypertensive headaches, cardiac ailments, and strokes.
Digits manifest deviation, with widened interphalangeal spaces and disorganized creases, commonly attributable to hepato-biliary disturbances affecting the gastric-splenic axis.
Phalangeal fractures, upon consolidation, result in complete loss of digital articulation, with affliction of the pollex precluding interdigitation, denoted as phalangeal union ailment, constituting a rare hereditary osseous pathology.
Upon ocular closure and orthostatic poise, with both hands extended horizontally and digits splayed, subtle tremors ensue, indicative of hyperthyroidism.
Subcutaneous desiccation of manual cellular constituents engenders dermal corrugation and desiccation of the palmar surface, mimicking the effect of prolonged immersion in aqueous medium, colloquially termed “washerwoman’s hands,” frequently encountered in acute gastrointestinal maladies, characterized by severe and recurrent emetic episodes.
Palm muscular atrophy, characterized by profound wasting, particularly evident in the thenar and hypothenar eminences, results in planar transformation reminiscent of simian upper limbs, referred to as “simian digits,” often associated with brachial neuralgia or inflammatory processes.
Palmar edema concomitant with digital paresthesia portends cardiac pathology.
Global palmofascial hypertrophy with concomitant digitocarpal shortening and thickening, coupled with prominent zygomatic, mandibular, and frontal protuberances, is characteristic of adult pituitary adenomas.
Palmar bullae, desquamation, and pruritus denote superficial mycotic invasions, colloquially labeled as “avian talons affliction.”
The veins protruding on the palm and fingers are indicative of intestinal stasis. The skin on the back of the hand is parched and wrinkled, with finger joints stiff and unyielding. Upon touch, the hands feel icy cold, a perennial condition characteristic of acral coldness syndrome, commonly found in the elderly and infirm. If the coldness is intermittent, accompanied by excruciating abdominal pain, pallor, and profuse cold sweats, it resembles symptoms typical of periodic worm infestation.
