The capitate fracture occurs at the neck level and when the body is displaced dorsally with the perilunar dislocation, the unsupported head cannot remain in(More)
The collateral ulnar ligament of the first metacarpo-phalangeal joint was studies in anatomical specimens in order to evaluate the relationship between pathological anatomy of the lesion and joint laxity. The clinical and X-ray evaluation of the valgus stretched joint led to the correct indications for treatment.
The authors report 40 cases of lesions of the ulnar part of the first metacarpo-phalangeal joint. In their experience only the main collateral ligament's lesions (alone or associated) need a surgical treatment. Only a correct diagnosis and early treatment lead to a complete functional recovery.
