ABSTRACT
@#Introduction: The current standard treatment for ankle syndesmosis injury is static screw fixation. Dynamic fixation was developed to restore the dynamic function of the syndesmosis. The purpose of this study was to determine that which of static screw fixation and dynamic fixation is better for treatment of ankle syndesmosis injury in pronationexternal rotation fractures. Materials and methods: Thirty patients were treated with dynamic fixation (DF group) and 28 patients with static screw fixation (SF group). The primary outcome was Olerud–Molander Ankle Outcome Score. The secondary outcome were Visual Analogue Scale score and American Orthopedic Foot and Ankle Society score, radiographic outcomes, complications and cost effectiveness. To evaluate the radiographic outcome, the tibiofibular clear space, tibiofibular overlap, and medial clear space were compared using the pre-operative and last follow-up plain radiographs. To evaluate the cost effectiveness, the total hospital cost was compared between the two groups Results: There was no significant difference in primary outcome. Moreover, there were no significant difference in secondary outcome including Visual Analogue Scale score and American Orthopedic Foot and Ankle Society score and radiographic outcome. Two cases of reduction loss and four cases of screw breakage were observed in the SF group. No complication in the DF group was observed. Dynamic fixation was more cost effective than static screw fixation with respect to the total hospital cost. Conclusion: Although dynamic fixation provided similar clinical and radiologic outcome, dynamic fixation is more cost effective with fewer complications than static screw fixation in ankle syndesmosis injury of pronation-external rotation fractures.
ABSTRACT
PURPOSE: To introduce reliable and newly developed radiographic measures based on a lateral ankle radiograph to assess a syndesmotic reduction after screw fixation and to compare with the radiographic measures based on the anteroposterior (AP) and mortise radiographs. MATERIALS AND METHODS: The postoperative ankle radiographs of 34 ankle fracture cases after screw fixation for concurrent syndesmosis injury were reviewed. Two radiographic parameters were measured on each AP and mortise radiograph; tibiofibular clear space (TFCS) and tibiofibular overlap (TFO). Five radiographic parameters were measured on the true lateral radiographs; the anteroposterior tibiofibular (APTF) ratio, anterior tibiofibular ratio (ATFR), posterior tibiofibular ratio (PTFR), distances of intersection of the anterior fibular border and the tibial plafond to anterior cortex of the tibia (AA′), and the intersection of posterior fibular border and tibial plafond to the tip of the posterior malleolus (BB′). In addition, the distance (XP) between the fibular posterior margin (X) crossing tibial plafond or the posterior malleolus and posterior articular margin (P) of the tibial plafond was measured on the lateral view. RESULTS: Using TFCS and TFO in the AP and mortise radiographs, malreductions of syndesmosis were estimated in 17 of 34 cases (50.0%). Using the introduced and developed radiographic measures in the lateral radiographs, syndesmotic malreductions were estimated in 16 out of 34 cases (47.1%). Seventeen cases (50.0%) showed no evidence of postoperative diastasis using the radiographic criteria on the AP and mortise view, 10 cases (58.8%) of whom showed evidence of a malreduction on the lateral radiograph. The newly developed measurements, XP, were measured 0 in 11 out of 34 cases (32.4%). CONCLUSION: The reduction of syndemosis after screw fixation can be accurately assessed intraoperatively with a combination of several reliable radiographic measurements of the lateral radiograph and traditional radiographic measurements of the AP and mortise radiograph.

Ankle syndesmosis injury is one of the most common ankle fractures complicated with injury,but there is certain challenges with diagnosis and treatment.The treatment of lower tibia and fibula injury is the main surgical treatment,the key is anatomical reduction.Along with some new treatment methods,the treatment effect of the lower tibia and fibula screws has been questioned more and more,And there is still a controversy on whether the removal of the lower tibia and fibula screws.Now for the ankle syndesmosis injury treatment were summarized.
ABSTRACT
PURPOSE: The purpose of this study was to evaluate the clinical and radiologic outcome of syndesmosis fixation using TightRope™ (Arthrex, Naples, FL, USA) in acute syndesmosis injuries. MATERIALS AND METHODS: Twenty-five consecutive patients with acute syndesmosis injuries, treated using TightRope™, were reviewed. Patients were evaluated preoperatively and at the last follow-up (at least 12 months postoperatively). Clinical outcomes were assessed using American Orthopaedics Foot and Ankle Society (AOFAS) ankle-hindfoot score and self-subjective satisfaction survey. Three radiologic parameters were evaluated two times at the preoperative and final follow up from the nonweightbearing ankle anteroposterior radiographs. RESULTS: The mean AOFAS ankle-hindfoot score was 95.5 at the final follow-up. According to the satisfaction survey, 21 patients chose excellent, and four patients chose good. All radiologic parameters, including the mean tibiofibular clear space, mean tibiofibular overlap, and mean medial clear space on nonweightbearing ankle anteroposterior view, significantly improved after surgery. Complications occurred in only one patient who experienced knot irritation with infection. CONCLUSION: The short-term surgical results of syndesmosis fixation using TightRope™ were good to excellent, both clinically and radiographically. These results suggest that the fixation using TightRope™ is a valid option for acute syndesmosis injury.
