Metacarpophalangeal joint dislocation of the thumb in children.
There are few reports describing dislocation of the metacarpophalangeal joint of the thumb in children. This study describes the clinical features and outcome of 37 such dislocations and correlates the radiological pattern with the type of dislocation. The mean age at injury was 7.3 years (3 to 13). A total of 33 children underwent closed reduction (11 under general anaesthesia). Four needed open reduction in two of which there was soft-tissue interposition. All cases obtained a good result. There was no infection, recurrent dislocation or significant stiffness. So-called 'simple complete' dislocations that present with the classic radiological finding of the joint at 90 degrees dorsal angulation may be 'complex complete' injuries and require open reduction.
