Introduction:
Complex intra-articular distal radius fractures with severe comminution or fragment rotation may be difficult to reduce using conventional fixation. We describe a dorsal salvage strategy, the Marseille Approach for Radius Salvage (MARS), enabling direct articular visualization in selected cases.
Hypothesis:
The MARS strategy allows reliable reduction and acceptable short-term functional outcomes in fractures not amenable to standard fixation.
Materials And Methods:
Single-center prospective case series (May 2021-October 2025). CT assessed reduction quality (step-off ≤ 2 mm). Functional outcomes at 1 year included motion, grip strength, pain, and QuickDASH.
Results:
Among 252 intra-articular fractures, 12 patients were included. All achieved satisfactory reduction on CT with maintenance at 6 months. At 1 year, pronosupination was preserved with mild extension loss and satisfactory pain and QuickDASH scores. One superficial infection and one mild tendon irritation requiring plate removal occurred; no tendon ruptures or CRPS were observed.
Discussion:
The MARS strategy enables direct articular visualization and stable reconstruction and may be useful in fracture-dislocations or markedly rotated fragments where conventional techniques are challenging.
Conclusion:
MARS strategy represents a pragmatic salvage option for highly complex intra-articular distal radius fractures when conventional strategies are insufficient.
Level Of Evidence:
III; Prospective case series.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
