Mini-Invasive Surgery for Distal Radius Fractures: A Double Incision under 12 mm.

Distal radius fracture is one of the most common lesions in adults. Surgical techniques have evolved considerably with a clear tendency toward mini-invasive techniques.  Our aim is to push the limits to a 12 mm approach and evaluate its clinical and radiological results.  Ten fractures in nine patients were operated by a double incision with mean size 11.50 ± 3.41 mm (range 8.00-1.00) and using a specially designed volar distal locking plate.  At the latest follow-up, visual analogue scale score for pain (0.20 ± 0.63 during rest and 0.60 ± 1.07 while making efforts) and quick DASH (quick Disabilities of the Arm, Shoulder and Hand) score (6.14 ± 7.43) were extremely low. All the range of motion parameters and grip strength were above the 95% barrier of the contralateral side, with exception of ulnar deviation. Radiological parameters obtained were located within the normal ranges. Time to return to independent daily tasks and work was 6.67 ± 5.15 and 10.14 ± 14.24 days, respectively. One case of transient carpal tunnel syndrome was solved with watchful waiting and one case of extensor tendons impingement was improved after plate removal. All patients were completely satisfied at the end of the treatment.  In conclusion, mini-invasive volar technique for distal radius fractures with special designed plates in carefully selected patients allowed us to obtain good clinical and radiological results, minimal complications, fast recovery, and high-satisfactory rates.  This is a Level IV, case series study.
