Comparison of therapeutic effects between double tension band steel wire and hollow tension screw in the treatment of tibial tubercle avulsion fractures in adolescents
Objective To compare the clinical efficacy of double tension band steel wire with hollow tension screw in the treatment of tibial tubercle avulsion fractures in adolescents.Methods A retrospective analysis was conducted on the clinical data of 36 patients with tibial tubercle avulsion fractures who visited our hospital from July 2019 to December 2022.They were divided into two groups based on different treatment methods.The experimental group consisted of 15 patients who were fixed with double tension band steel wire.The control group of 21 cases was fixed with hollow tension screws.Regular follow-up visits will be conducted at the orthopedic clinic after surgery to record the time required for the patient's knee to tolerate weight bearing,flexion to 120°,complete range of motion,and unrestricted mobility.During follow-up,complications such as incision infection,internal fixation stimulation,knee joint varus and varus,and unequal length of both lower limbs were recorded.AP and lateral X-ray films of the knee joint immediately after surgery,1 month and 6 months after surgery were checked to evaluate the fracture healing status.Results There was no statistically significant difference in preoperative general information such as age,gender,body mass index,follow-up time,and time from injury to surgery between the experimental group and the control group(P>0.05).The average starting weight bearing time of the experimental group(4.87±1.13 weeks)and the required time(6.10±1.51 weeks)were earlier than that of the control group with statistically significant differences(P<0.05).Progress in postoperative mobility was observed in the experimental group,with an average recovery of 120° knee flexion at(10.67±3.11)weeks and complete mobility at(13.47±2.20)weeks.The time required for recovery was shorter than that of the control group(13.24±3.36)weeks and(15.62±2.89)weeks,with statistically significant differences(P<0.05).The postoperative recovery was normal,with unrestricted activity.The experimental group took an average of(17.80±2.21)weeks,while the control group took an average of(20.57±2.56)weeks.There were statistically significant differences between the two groups(P<0.05).No postoperative complications occurred in both groups of patients during postoperative follow-up.Conclusions Both double tension band steel wire and hollow tension screw fixation are effective for tibial tubercle avulsion fractures in adolescents.Double tension band fixation is more stable for fractures,which can promote early rehabilitation exercise for patients,thereby restoring knee joint function,and enabling patients to resume normal activities as soon as possible.
