Impact of percutaneous poking reduction combined with minimally invasive plate internal fixation on foot function and complications of patients with Sanders type II and III calcaneal fractures

摘要

Objective: To investigate the impact of percutaneous poking reduction (PPR) combined with minimally invasive plate internal fixation on foot function and complications of Sanders type II and III calcaneal fractures (CFs). Methods: In this prospective study, 76 patients with Sanders type II and III CFs were randomly divided into the control group (n=38, “L” incision open reduction and plate internal fixation) and the study group (n=38, PPR combined with minimally invasive plate internal fixation (MIPIF)). The operation related indexes, skin necrosis rate, Gissane angle, Bohler angle, calcaneal height and ankle-hindfoot score before and after the operation were compared between the two groups. Complications of the two groups were recorded. Results: Compared with the control group, the operation time of the study group was significantly prolonged, but the intraoperative blood loss was significantly reduced, and the fracture healing time and hospitalization time were significantly shortened (P0.05). The Gissane angle, Bohler angle and calcaneal height of the two groups increased 6 months after the operation, and the changes in the study group were more obvious than those in the control group (P0.05). Six months after the operation, the ankle-hindfoot scores of the two groups significantly increased, and the changes of the study group were more significant than that of the control group (P0.05). The total incidence of postoperative complications in the study group was significantly lower than that in the control group (P0.05). Conclusion: PPR combined with MIPIF can significantly promote the healing of Sanders type II and III CFs and the recovery of the Gissane angle and Bohler angle, effectively improve the foot function of patients and induce fewer complications, which is worthy of clinical promotion.
