ABSTRACT
BACKGROUND:Although traditional screw fixation has been successful in treating ankle fractures,rigid fixation solutions tend to restrict ankle movement and delay fracture healing,whereas elastic fixation is more compatible with human mechanics and has unique advantages in patients with ankle fractures. OBJECTIVE:To compare the clinical effectiveness of elastic fixation and absolute fixation in repairing ankle fractures in the elderly with lower tibiofibular instability. METHODS:The clinical data of 108 elderly ankle fractures with lower tibiofibular instability in Hengshui People's Hospital from August 2019 to August 2021 were retrospectively collected.They were divided into screw group and elastic fixation group(n=54 per group)according to the surgical protocol,and traditional screw internal fixation and elastic internal fixation were performed respectively.The perioperative indicators,surgical results,economic benefits,and American orthopedic foot and ankle society scores were collected and compared between the two groups.Serum tumor necrosis factor-α,interleukin-8 levels,ankle cavity width,depth,and lower tibiofibular space were compared before and after surgery. RESULTS AND CONCLUSION:(1)The full weight-bearing time was shorter in the elastic fixation group than that in the screw group;the operating angle was greater in the elastic fixation group than that in the screw group,and the complication rate was lower in the elastic fixation group than that in the screw group(P<0.05).(2)Serum tumor necrosis factor-α and interleukin-8 levels in the elastic fixation group were lower than those in the screw group 3 days after surgery(P<0.05).(3)American orthopedic foot and ankle society scores in the two groups were higher than those before surgery at 6 and 12 months after surgery,and the depth and width of the inferior tibiofibular space and ankle cavity were lower than those before surgery(P<0.05);but no significant difference was detected between the two groups(P>0.05).(4)There was no significant difference in the excellent and good rate between the two groups at 12 months after surgery(P>0.05).(5)There was no significant difference in the comparison of direct non-medical costs,direct medical costs,and total costs between the two groups(P>0.05).(6)It is indicated that elastic fixation for the repair of ankle fractures with lower tibiofibular instability in the elderly can obtain effective outcomes,which can shorten the time of complete weight-bearing,diminish complications,and alleviate inflammatory stress.
ABSTRACT
BACKGROUND:High ankle sprain is easily missed and leads to ankle dysfunction.Arthroscopy can detect hidden high ankle sprain.Suture-button elastic fixation can restore the biomechanical stability of the distal tibiofibular syndesmosis. OBJECTIVE:To explore the clinical efficacy of Suture-button elastic fixation for high ankle sprain under ankle arthroscopy. METHODS:A retrospective analysis was performed on 40 cases of high ankle sprain patients treated with Suture-button elastic fixation under ankle arthroscopy from August 2019 to August 2021 in the Department of Foot and Ankle Surgery,Wuhan Fourth Hospital.All patients underwent Suture-button elastic fixation.The American Orthopedic Foot and Ankle Society function score,Visual Analog Scale pain score,ankle range of motion,preoperative imaging data,and arthroscopic tibiofibular syndesmosis separation degree were recorded.Meislin criteria were used to evaluate the curative effect and postoperative complications were recorded. RESULTS AND CONCLUSION:(1)40 patients were followed up for 16-48 months after operation.(2)At the last follow-up,American Orthopedic Foot and Ankle Society score was(88.95±6.64 points).Visual Analog Scale score was(1.78±1.23 points).Ankle dorsiflexion range of motion was(33.50±5.79 degrees).Ankle plantarflexion range of motion was(34.50±5.97 degrees).There were statistically significant differences before and after surgery(P<0.05).(3)There was a low positive correlation between the radiographic separation index and the degree of arthroscopic separation(r=0.612,P<0.01).(4)The curative effect was evaluated by Meislin standard,with an excellent and good rate of 95%(38/40).Postoperative ankle joint pain was relieved,and ankle joint activities were significantly improved.(5)During the follow-up period,all patients had no nerve injury or incision infection.In 1 patient,the internal fixation was removed due to skin irritation and squatting sensation after operation.(6)It is concluded that Suture-button elastic fixation for high ankle sprain is effective under ankle arthroscopy in restoring ankle function and maintaining joint stability without the need for secondary removal,and it is worth clinical application.
ABSTRACT
OBJECTIVE@#To study the effectiveness of TightRope elastic fixation combined with functional total repair of the inferior tibiofibular ligament in the treatment of distal tibiofibular syndesmosis injury.@*METHODS@#The clinical data of 34 patients with distal tibiofibular syndesmosis injury who met the selection criteria between January 2020 and January 2022 were retrospectively analyzed, and they were divided into improved group (TightRope elastic fixation combined with functional total repair of inferior tibiofibular ligament) and control group (distal tibiofibular screw fixation) according to the surgical methods, with 17 cases in each group. There was no significant difference in age, gender, body mass index, fracture type, and other baseline data between the two groups (P>0.05). The operation time, intraoperative blood loss, and complications were recorded in the two groups. The American Orthopaedic Foot and Ankle Society (AOFAS) score, ankle metatarsal flexion and dorsal extension range of motion were used to evaluate the ankle function. The patient satisfaction survey was conducted at last follow-up.@*RESULTS@#All 34 patients were followed up 8-20 months, with a median of 13 months. The operation time and intraoperative blood loss in the improved group were significantly longer than that in the control group (P<0.05). In the improved group, no infection or poor reduction occurred, and only 1 patient had TightRope knot reaction at 6 months after operation. In the control group, there were 2 cases of poor reduction, 1 case of lower tibiofibular screw rupture, and 1 case of subcutaneous infection (cured after anti-infection treatment). There was no significant difference in the incidence of complications between the two groups (P>0.05). At last follow-up, the AOFAS score and ankle metatarsal flexion and dorsal extension range of motion of the improved group were significantly better than those of the control group (P<0.05). The satisfaction rates of patients in the improved group and the control group were 94.1% and 82.4%, respectively, showing significant difference (P<0.05).@*CONCLUSION@#TightRope elastic fixation combined with functional total repair of inferior tibiofibular ligament in the treatment of distal tibiofibular syndesmosis injury has sufficient fixation strength, and can achieve better effectiveness and joint function compared with traditional screw fixation.

BACKGROUND: In the clinical treatment of distal tibiofibular syndesmosis injury, Suture-Button fixation technique can achieve similar results to, even better results than, those of screws, but it cannot fully recover the anatomical reduction and activity to those before injury. However, the optimal treatment of distal tibiofibular syndesmosis injury is still controversial. OBJECTIVE: To systematically evaluate Suture-Button fixation and screw fixation for the treatment of distal tibiofibular syndesmosis injury. METHODS: EMBASE, Cochrane database, PubMed database, Wanfang database, and CNKI were searched to retrieve randomized or non-randomized controlled trials regarding Suture-Button fixation and screw fixation for the treatment of distal tibiofibular syndesmosis injury published from January 2005 to January 2019. The quality of the included studies was strictly evaluated. Relevant data were extracted. A meta-analysis of all outcome measures was performed using RevMan 5. 3 software. RESULTS AND CONCLUSION: (1) Twelve studies were included, including 4 randomized controlled trials and 8 cohort studies, involving 564 patients. (2) Meta-analysis results showed that Suture-Button fixation had shorter full weight-bearing time [WMD=-1. 50, 95%CI(-2. 08, -0. 92), P 0. 05). (3) These findings suggest that compared with screw fixation, Suture-Button fixation for the treatment of distal tibiofibular syndesmosis injury leads to better recovery of ankle joint function and an earlier time point for full weight bearing and does not need to consider the risk of screw fracture during the surgery. In addition to screw fixation, Suture-Button fixation is an effective way to treat distal tibiofibular syndesmosis injury.
ABSTRACT
Objective: To review the research progress in the diagnosis and treatment of distal tibiofibular syndesmosis injury. Methods: The recent literature about distal tibiofibular syndesmosis injury was reviewed and analyzed. Results: Distal tibiofibular syndesmosis injury is commonly seen in ankle joint injury, the anatomical complexities make diagnosis and treatment difficult. Preoperative physical examination, radiologic evaluation, and intraoperative stress-testing are important for the diagnosis. Aggressive treatment is also recommended for these injuries to prevent long-term chronic instability. Internal fixation is the main treatment, including metal screw, degradable screw, elastic fixation, and hybrid techniques. Metal screw fixation is still the current mainstream, but elastic fixation represented by Suture-button is more in line with the physiological characteristics of ankle joint, and the rate of secondary operation is low while the clinical outcome is satisfactory. The application prospect of elastic fixation is worthy of expectation. Conclusion: It's crucial for patient with ankle fracture to repair the distal tibiofibular syndesmosis injury. How to diagnose the injury more accurately and simply, how to increase the success rate of reduction, and how to reduce the complications of surgery are still worthy for further exploration.
