The graft is delivered through the osseous tunnel, recreating the beak ligament, while its insertion on the second metacarpal base serves as the intermetacarpal
Soyer (8) suggested that transarticular K-wire fixation alone would not suffice in maintaining the abduction and pronation of metacarpals; thus, a second K-wire was necessary for intermetacarpal fixation.
Closed reduction intermetacarpal Kirschner wire fixation in the treatment of unstable fractures of the base of the first metacarpal.
After 4 weeks of thumb spica immobilization, the intermetacarpal K-wire was removed, and ROM exercises were started.
The ligaments providing stability to the joint are the anterior oblique ligament (AOL), intermetacarpal ligament (IML), dorsoradial ligament (DRL), posterior oblique ligament (POL), and ulnar collateral ligament (UCL) [19, 20].
At the base of the fourth and fifth metacarpals, intermetacarpal
wire insertion mimics the attachment of intermetacarpal
Ligamentous CMC joint stability is provided by the anterior-volar-oblique (beak) ligament, the posterior oblique, dorsal radial, and anterior and posterior intermetacarpal
In one limb the radial artery dipped in 2nd intermetacarpal
space and took part in formation of deep palmar arch with superior deep palmar branch of ulnar artery.
Ramification pattern of intermetacarpal
branches of the deep branch (ramus profundus) of the ulnar nerve in the human hand.
It is stabilized by four ligaments: anterior oblique, intermetacarpal
, radial collateral, and posterior oblique ligaments.
(9) Fracture of trapezium, Axial load with trapezoid and hyperextended second/third wrist intermetacarpal
ligament rupture Watanabe, et al.
Secondary stabilizers of the TM joint include the first intermetacarpal
(IM) ligament, the ulnar collateral ligament (UCL), the posterior oblique ligament (POL), and the dorsoradial ligament (DRL).
