Outline
Text
Objectives/Interrogation: Irreducible dislocations of the metacarpophalangeal joints were described very early in the literature, as the therapy initially appeared simple, but then often ended in a disaster.
Only about 400 cases of this dislocation could be found in the literature. Most affect the thumb and are dorsal dislocations. The dorsal dislocations are also much more often in the fingers. Palmar dislocations are a great rarity.
Methods:
We report very inessential cases from 250 years of literature, a classification of irreponible dislocations and our 24 cases, where we can present 2 palmar dislocations of the thumb and 2 palmar dislocations of the fingers with very interesting injury mechanisms.
Results and Conclusions: The opposing repositioning obstacle is very different on the thumb, while it is always the palmare plate on the fingers. A closed reduction is possible only after the Roser-Hey principle (1856) and Farabeuf (1878) principle. Operatively, dorsal dislocations are easiest after Farabeuf of posterior with cleavage of the palmar plate.
In palmar dislocations both collateral ligaments are always torn and need a primary reconstruction. Nevertheless, the prognosis of palmar dislocations is poor.
