Minimally Invasive Treatment of Die-Punch Fractures and Related X-Ray Parameters
Abstract
Objective: This study aimed to assess the efficiency and safety of minimally invasive treatment for die-punch fractures using X-ray parameters.
Methods: From May 2020 to May 2022, 32 patients (32 wrists; minimally invasive group) underwent percutaneous bony distraction, followed by external fixation. For comparison, we retrospectively reviewed another 35 patients (35 wrists; plating group) who underwent open reduction and internal fixation with plate and crew systems. Wrist movement was assessed. X-ray parameters and wrist pain were assessed. Wrist function was assessed using the Mayo Wrist Score. Patient satisfaction was assessed using the Short Assessment of Patient Satisfaction.
Results: The mean age of the minimally invasive group was 38.6±12.3 years (range, 24-52 years). There were types B3 (n=11), C1 (n=10), C2 (n=8), and C3 (n=3). Bone healing achieved in all patients after 5.8±1.6 weeks. The mean age of the plating group was 37.1±13.2 years (range, 27-50 years). There were types B3 (n=13), C1 (n=9), C2 (n=9), and C3 (n=4). Bone healing achieved in all patients after 6.3±1.6 weeks. Two years after surgery, there were significant differences in radial height (12.1±2.6 mm versus 10±2.5 mm; pversus 1.4±0.9 mm; pversus 3±3; pp>0.05), grip strength (p>0.05), Mayo Wrist Score (p>0.05), or patient satisfaction (p>0.05).
Conclusion: When treating die-punch fracture of distal radius, directly lifting the collapsed fragments through percutaneous bone distraction can effectively…
