Effect of delayed distal radius fracture fixation on the difficulty of surgical operation

PURPOSE: The effect of delayed distal radius fracture (DRF) fixation by volar locking plates (VLPs) on the operative time, rate of bone graft use and need for additional surgical incisions was analyzed. Short- and mid-term outcomes were compared between early and delayed DRF fixation. METHODS: A retrospective cohort review of DRFs treated with VLPs was performed. The effects of delayed fixation were analyzed by 1) comparing intraoperative and radiographic parameters and follow-up outcomes between early fixation (EF, 1–10 days) and late fixation (LF, ≥11 days), 2) predicting the prolonged operative time using linear regression analysis, and 3) predicting the rate of bone graft use and additional incision using odds ratios. RESULTS: Of 104 patients, 51 and 53 were in the EF and LF groups, respectively. EF showed a significantly shorter operative time, lower rate of bone grafting and fewer additional incisions (94.80 vs. 123 minutes, 3.92% vs. 26.18% and 2% vs. 20.45%, respectively). Radiographic parameters, immediate postoperative pain and wrist range of motion were significantly better in the EF group. However, the visual analog scale (VAS) pain and Patient-Rated Wrist Evaluation (PRWE) scores were not different at the 12-month follow-up. For every day of delay, the operation was prolonged by 2.17 min, the rate of bone grafting increased by 8%, and the chance of additional incisions increased by 8%. CONCLUSION: Delayed DRF fixation affects intraoperative and postoperative outcomes. We encourage internal fixation for DRFs as early as possible to reduce surgical complexity and improve postoperative outcomes.
