摘要

Background

Distal radius fractures represent about one-sixth of all fractures treated in emergency departments. Treatment options include plaster immobilization, K-wiring, external fixation and volar plating. Conventional open reduction and internal fixation (ORIF) with the Henry’s approach allows stable fixation but requires wide exposure and soft-tissue dissection. Minimally invasive plate osteosynthesis (MIPO) has been developed to reduce surgical trauma, preserve biology and potentially improve cosmetic outcomes. This study evaluated the outcomes of distal radius fractures managed using a minimally invasive approach.

Methods

From October 2018 to September 2020, 34 patients with distal radius fractures underwent MIPO in a prospective study. Outcomes were assessed at 6–9 months using the Visual Analog Scale (VAS) for pain, Disabilities of the Arm, Shoulder and Hand (DASH) score, Modified Mayo Wrist Score, Patient and Observer Scar Assessment Scale (POSAS), grip and pinch strength, range of motion, radiological parameters, return-to-work time and complications.

Results

The mean incision size was 2.67 cm. Range of motion, grip and pinch strength were restored to 94–96% of the contralateral side. The mean VAS pain score was 0.24 ± 0.5, mean DASH score was 2.64 ± 0.97 and mean Modified Mayo Wrist Score was 85 ± 5.08.Modified MAYO score was excellent in 50% of patients and good in the remaining. Radiological criteria for optimal fixation were met in all cases. Mean POSAS scores were 11.71 ± 4.52 (patient) and 14.85 ± 3.89 (observer). The mean time to return to work was 28.06 ± 7.27 days. One patient developed transient CRPS; no major complications were observed.

Conclusions

MIPO for distal radius fractures appears to be a safe and effective technique, providing reliable clinical, radiological, functional and cosmetic outcomes with high patient satisfaction.
