Does arthroscopic assistance improve reduction in distal articular radius fracture? A retrospective comparative study using a blind CT assessment

The objective of this study was to compare the articular reduction in two groups of patients with a distal articular radius fracture who underwent surgery with versus without arthroscopic assistance. The initial hypothesis of this study is that arthroscopic assistance does not improve reduction in distal articular radius fractures.
The study was retrospective (1/04/2014–01/04/2017) and included 41 patients: 23 had arthroscopically assisted osteosynthesis, and 18 had not. All patients included had CT before and 3 months after surgery. All radiographic and CT measurements were retrospectively taken by an independent radiologist who did not know which operative technique was performed. Secondary judgement criteria were clinical analysis at 1-year follow-up and tourniquet time. We also reported all soft tissue injuries diagnosed and repaired and postoperative complications.
At the third month, articular step was 0.91 ± 1.25 mm (arthroscopy) and 1.41 ± 1.68 mm (no arthroscopy), without statistical difference (p = 0.3756). No difference was found for articular gap between the two groups [arthroscopy (0.55 ± 1.04 mm), (no arthroscopy (0.82 ± 1.54 mm)] (p = 0.8574). Except for the tourniquet time, clinical results at 1-year follow-up were not different. One patient of each group had a scapholunate pinning, and 6 patients of the arthroscopy group had a TFCC 1B injury, which was repaired.
This study did not demonstrate that arthroscopic assistance improves step and gap reduction of articular distal radius fracture, confirming initial hypothesis and recent literature data.
