AbstractInjuries of the metacarpophalangeal joints of the thumb and fingers are of a bony or ligamentous nature. They can heal without subsequent problems if correctly diagnosed and treated but incorrect or absent diagnostics and therapy can result in chronic instability, dislocation, fusion as well as subsequent arthritis and functional limitations. They can lead to substantial impairment of the gripping function. Fractures with inclusion of joints and with fragments sufficiently large for refixation are as a rule treated operatively just as differences in torsion and instability. Persisting instabilities are secondarily stabilized by ligamentoplasty and arthritis of the metacarpophalangeal joint of the thumb is treated by fusion. For metacarpophalangeal joints of the fingers the main concern is preserving motion. Established salvage operations for arthritis include denervation, resection arthroplasty and systematic arthrolysis for impairment of the joint and contractures with intact joint surfaces. Even in chronic conditions, with appropriate treatment good functional results for metacarpophalangeal joints of the thumb and fingers can be achieved. This article presents the current pathophysiological principles and concepts for diagnostics and therapy of acute and chronic injuries of the metacarpophalangeal joints of fingers and thumbs.
