Abstract:
Objective
To investigate the clinical efficacy and influencing factors of double reverse traction external fixation frame combined with intramedullary nailing in the treatment of multiple tibial fractures.
Methods
The clinical data of 110 patients with multiple tibia fractures who were admitted to the Department of Orthopedics and Traumatology in Affiliated Hospital of Traditional Chinese Medicine of Southwest Medical University from February 2021 to December 2022 were selected, and they were divided into 55 cases of the double-reverse retractor combined with intramedullary nailing group and 55 cases of the traditional compression plate combined with intramedullary nailing group according to the different treatment modalities, and the differences in the surgery-related indexes, ankle function (Kofoed score), joint mobility and fracture healing rate at 3 months after surgery and the factors influencing the prognosis of the fracture were analyzed.
Results
The operation time[(64.29±17.46) min], intraoperative bleeding[ (41.99±6.21) ml], fracture end dissection rate (16.36%), fracture healing time[(21.82±5.76) weeks], and time to get out of bed [ (4.24±1.29) weeks]were lower in the double retractor combined with intramedullary nailing group than in the traditional compression plate combined with intramedullary nailing group [(89.71±23.58) min, (56.69±12.00) ml, 45.45%, (30.87±7.77) weeks, (6.36±1.75)weeks](t/χ2=5.247, 6.966, 10.890, 6.942, 7.236, P<0.05), and the fracture healing rate was higher than that of the traditional compression plate combined with intramedullary nailing group at 3 months postoperatively (85.45% vs 67.27%)(χ2=5.037, P<0.05). Repeated-measures ANOVA showed that the Kofoed scores of both groups at the time of external fixation and at the last follow-up were higher than those of the preoperative period (P<0.05), and the Kofoed scores at the time of external fixation and at the last follow-up were higher in the double-reverse retractor combined with intramedullary nailing group [(83.59±5.14)points and (94.67±5.53)points]than those in the conventional compression plate combined with intramedullary nailing group [(79.54 ±5.21) points, (88.39±5.42) points](t=3.191, 4.651, P<0.05). The ankle joint range of motion and knee joint range of motion at the last follow-up were higher than those at external fixation in both groups (P<0.05), and the ankle joint range of motion and knee joint range of motion at external fixation and at the last follow-up in the patients in the double-reverse retractor combined with intramedullary nailing group [(50.30±4.51)°, (100.81±11.96)°]were higher than those in the traditional compression plate combined with intramedullary nail group [(37.21 ±4.66)°, (82.72±8.96)°](t=11.678,6.660, P<0.05). Patients were categorized into healed and non-healed groups according to their postoperative fracture healing status. Logistic regression analysis showed that age (≥60 years), cause of fracture (high energy), time from injury to treatment (≥6 h), and timing of soft tissue repair (second stage repair) were risk factors for fracture healing, and albumin level was a protective factor for fracture healing (OR=9.369, 4.961, 6.825, 10.000, 0.830, P<0.05).
Conclusion
The combination of dual reverse traction device and temporary external fixator for the treatment of multiple tibial fractures has a good clinical effect, which can effectively improve ankle joint function and joint mobility, promote postoperative fracture healing. ≥60 years old, high energy fracture, time from injury to treatment ≥6 hours, secondary soft tissue repair, and albumin level are factors related to fracture healing. Clinical attention should be paid to these factors.
