Arthroscopic Scaffold Fixation Technique for Intra-articular Distal Radius Fractures.

Area of Science:

• Orthopedic Surgery
• Arthroscopy
• Traumatology

Background:

• Displaced intra-articular fractures of the distal radius are complex injuries requiring precise management.
• Traditional open reduction and internal fixation may have limitations in visualizing and restoring the articular surface.

Purpose of the Study:

• To describe a minimally invasive arthroscopic-assisted technique for the reduction and internal fixation of displaced intra-articular distal radius fractures.
• To detail the use of subchondral wires and a volar locking plate for scaffold creation and indirect reduction.

Main Methods:

• Arthroscopic visualization and reduction of the anterior endplate articular surface.
• Placement of subchondral wires to create a scaffold for fracture stabilization.
• Indirect reduction of the distal fracture fragment using a volar locking plate.

Main Results:

• The described technique allows for precise reduction and fixation of the articular surface.
• The scaffold created by subchondral wires facilitates indirect reduction of the distal fragment.
• Correction of anteroposterior and radioulnar inclination is achieved via the volar locking plate.

Conclusions:

• Arthroscopic-assisted reduction and internal fixation is a valuable adjunct for managing complex distal radius fractures.
• This technique offers a minimally invasive approach to restore articular congruity and improve outcomes.
