[Palmar fixed angle plating systems for instable distal radius fractures].

Area of Science:

• Orthopedic Surgery
• Traumatology
• Radiology

Background:

• Distal radius fractures, especially with dorsal comminution and osteoporosis, present challenges with secondary dislocation and extensor tendon issues.
• Traditional dorsal plating can complicate reduction and may necessitate bone grafting.

Purpose of the Study:

• To evaluate the efficacy of fixed-angle devices applied via a palmar approach for treating distal radius fractures.
• To assess the rates of secondary dislocation, reduction control, and functional outcomes.

Main Methods:

• Retrospective evaluation of 62 patients (average age 55) treated with fixed-angle devices for distal radius fractures.
• Fractures classified using the AO Classification system (A2, A3, B3, C1, C2, C3).
• Follow-up averaged 11 months, assessing healing, secondary loss of reduction, and DASH scores.

Main Results:

• Fixed-angle devices provided stable fixation, preventing significant secondary loss of reduction in all cases.
• Palmar approach offered better visualization and control, minimizing the need for bone grafting.
• Low complication rates and early mobilization were observed, with a mean DASH score of 19.

Conclusions:

• Fixed-angle devices via a palmar approach are effective for treating distal radius fractures, including complex comminuted and osteoporotic types.
• This method enhances articular support, prevents secondary displacement, and facilitates early functional recovery.
• The technique demonstrates a favorable safety profile with reduced soft tissue complications.
