Articular Fragment Escape and Carpal Subluxation Following Distal Radius Fracture Fixation

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Skeletal Trauma

Background:

• Distal radius fractures are common, with volar locking plates being the standard surgical fixation.
• Complications, though rare, can include articular fragment escape leading to carpal instability.
• This complication is often associated with specific fracture patterns, particularly involving the volar or dorsal lunate facet.

Purpose of the Study:

• To describe the anatomy relevant to articular fragment escape after distal radius fracture fixation.
• To classify patterns of articular fragment escape following surgical fixation.
• To discuss strategies for preventing this complication.

Main Methods:

• Review of relevant anatomical structures.
• Classification of observed articular fragment escape patterns.
• Discussion of preventative surgical and postoperative management strategies.

Main Results:

• Identification of key anatomical landmarks critical for fragment stability.
• Categorization of fragment escape based on fracture patterns and fixation techniques.
• Emphasis on preoperative planning and appropriate implant choice for prevention.

Conclusions:

• Understanding specific fracture patterns is crucial for preventing articular fragment escape.
• Meticulous surgical technique, appropriate implant selection, and judicious postoperative immobilization are essential.
• Proactive management can minimize the risk of carpal instability following distal radius fracture fixation.
