| Objective To compare the efficacy of suture bridge technique and hollow screw compression in the treatment of avulsion fracture of tibial tubercle in adolescents.Methods A retrospective study was conducted to collect 37 cases of avulsion fracture of tibial tubercle in adolescents from October 2015 to October 2022 in the department of orthopedics of Zaoyang First People's Hospital. Among them, there were 36 males and 1 female; the age ranged from 13 to 17 years, with an average age of 15.2 years. According to the fixation method of the avulsion bone block, they were divided into two groups: Suture bridge group (absorbable double-row suture bridge fixation with belt anchor, 19 cases) and hollow screw group (ordinary hollow metal screw compression fixation, 18 cases). The knee flexion angle, Bostman function score at 1, 2, 3 months after operation and the last follow-up (>12 months), Tegner activity score at 3 and 6 months after operation and at the last follow-up (>12 months), the satisfaction of patients (Bostman function score classification) at 3 months after operation and at the last follow-up, and postoperative complications were compared between the two groups.Results The median follow-up time was 18 months (12 to 24 months). The knee flexion angle and Bostman function score of the suture bridge group were better than those of the hollow screw group at 1 month and 2 months after surgery, with statistical significance (P<0.05). The knee flexion angle and Bostman function score of the two groups were not statistically significant at 3 months after surgery and at the last follow-up (P>0.05). Tegner activity score at 3 months after surgery the suture bridge group was better than the hollow screw group, the difference was statistically significant (P<0.05), and there was no statistically significant difference in Tegner activity score 6 months after surgery and at the last follow-up (P>0.05). The satisfaction of patients 3 months after surgery (Bostman functional score classification) was better in the suture bridge group than in the hollow screw group. The difference was statistically significant (P<0.05), but there was no significant difference in patient satisfaction (Bostman functional score) between the two groups at the last follow-up (P>0.05). There were no significant differences in the incidence of postoperative complications between the two groups (P>0.05).Conclusion Compared with hollow screw or wire tension band fixation technique, suture bridge technique can achieve screw fixation strength, allow early knee flexion and extension exercise, less postoperative foreign body irritation, lower complication rate, and no need to remove internal fixation twice after fracture healing. |
