Anatomical variation of co-existence of 4th and 5th short metacarpal
bones, sesamoid ossicles and exostoses of ulna and radius in the same hand: a case report.
Review of imaging findings suggested the nidus was likely near the base of the second metacarpal
, accessible with a posterior approach.
The bony volar beak of the metacarpal
became recontoured into the smooth saddle joint, and the surrounding ligaments became the dominant stabilizing force of the joint during pinching activities.
Radiographs demonstrated no significant findings on the whole-body view, but a ventrodorsal wing film showed a moderately displaced, mid-diaphyseal, transverse fracture of the right major and minor metacarpal
bones (Fig 1).
Articular fracture of the base of the thumb metacarpal
: comparative study between direct open fixation and extrafocal pinning.
We saw extensive metallosis and damaged-appearing extensor indices (EI) and distal extensor carpi radialis longus (ECRL) tendons over the index metacarpal
[4,5] First dorsal metacarpal
artery arises directly from the radial artery between the base of thumb and the index metacarpal
, then divides into branches.
A midline dorsal longitudinal incision was made over the wrist from the midshaft of the third metacarpal
to the distal radius.
Two orthogonal view of radiographic examination confirmed short oblique fracture of metacarpal
in two animals and metatarsal fractures in three calves (Table 1).
fractures are common in adolescents and young active individuals.
