Pinning-in treatment according to the ISELIN technique of a Trapezo-metacarpal dislocation without ligamentoplasty

Trapezo-metacarpal dislocations are rare, accounting for only 1% of hand trauma. The mechanism is generally indirect by axial compression and retropulsion (Kindle theory) or shearing (Monsche theory). We report a clinical case this lesion which occurred in the context multiple Due to rarity entity, dislocation went unnoticed during first assessment 28-year-old patient admitted as part trauma road accident whose injury poorly understood. aim study highlight place pinning-in according ISELIN technique treatment rare entity assess functional hand’s prognosis after treatment.
