In general, together with the dorsal capsule, radial collateral ligament (RCL), and volar plate
, the UCL serves as a static stabilizer of the MCP joint.
Incidence of an anomalous course of the palmar cutaneous branch of the median nerve during volar plate
fixation of distal radius fractures.
Intramedullary nail versus volar plate
fixation of extra-articular distal radius fractures.

fixation of distal radius fractures: a cadaveric study," Annals of the Royal College of Surgeons of England, vol.
Although volar plate
fixation has become the gold standard in the treatment of unstable distal radius fractures, extensor tendon irritation and rupture are known complications of this procedure.

osteosynthesis," Orthopedics, vol.
Even comminuted fractures with dorsal metaphyseal instability can be fixed with a volar plate
. It has the advantages like early and better mobilization and function of hand, repair of ruptured tendons, less residual pain, stiffness, and restriction and best chance of restoring joint congruity.
What advantages does volar plate
fixation have over K-wire fixation for distal radius extension fractures in the elderly?
The volar plate
stabilizes the PIP joint, which helps prevent hyperextension.
Application of a volar plate
with angle-stable fixation has been used successfully in a number of cohort studies but needs to be examined in stringent trials to determine if there is any benefit when compared with other treatment modalities .
Treatment options include external fixation, distraction plate fixation using a dorsal approach, standard 3.5 mm LCP plates, and fixed angle volar plates
. Volar plate
fixation has been recognized to be an effective and safe treatment in unstable distal radius fractures.
Most injuries at this joint occur from forced extension, not flexion, and result in a volar plate
