Abstract
Objective: To evaluate the clinical efficacy of minimally invasive treatment using a Kirschner wire distractor for reverse traction closed reduction and hollow nail fixation in treating Sanders Type II and III calcaneal fractures.
Methods: A retrospective analysis was conducted on 33 patients with calcaneal fractures treated with the new technique (observation group) from January 2024 to December 2024, and another 33 patients treated with traditional open reduction and plate internal fixation (control group) from January 2023 to December 2023. Surgical indicators, fracture healing status, AOFAS ankle-hindfoot scores, radiological indicators (Böhler angle, Gissane angle), and postoperative complication rates were compared between the two groups.
Results: All 66 patients were followed up for 6 to 12 months. The observation group had significantly less intraoperative blood loss, shorter operation time, shorter hospital stay, and lower hospital costs compared to the control group (P < 0.01). However, the number of intraoperative fluoroscopies was higher in the observation group (P < 0.01). Callus formation occurred within 6 to 8 weeks, and fracture healing was completed within 12 to 18 weeks in both groups. At the 3-month follow-up, Böhler and Gissane angles showed significant improvement compared to preoperative values in both groups (P < 0.01), but there was no significant difference between the two groups at the 3-month follow-up (P > 0.05). Postoperative VAS pain scores on days 1, 2, and 3 and postoperative complication rates were significantly lower in the observation group (P < 0.05). The final follow-up AOFAS ankle-hindfoot scores and their excellent-good rate were significantly higher in the observation group (P < 0.05).
Conclusion: Minimally invasive treatment with a Kirschner wire distractor for reverse traction closed reduction and hollow nail fixation in calcaneal fractures results in less surgical trauma, shorter hospital stays, reduced hospital costs and intraoperative blood loss, faster restoration of calcaneal anatomy, and significantly reduced postoperative pain and complications. However, this approach increases intraoperative radiation exposure for both doctors and patients.
