Abstract Background Ankle syndesmosis injury is a common condition, and the injury mechanism can be sorted into pure syndesmosis injury, Weber-B, and Weber-C type fractures. This study aims to evaluate the treatment outcomes and stability of suture-button fixation for syndesmosis injury with different injury mechanisms. We hypothesized that injury mechanisms would alter the stability of suture-button fixation. Methods We retrospectively reviewed 63 patients with ankle syndesmosis injury who underwent surgery with TightRope (Arthrex, Naples, FL, USA) from April 2014 to February 2019. The stability of suture-button fixation with TightRope was evaluated by comparing the preoperative, postoperative, and final follow-up measurements of tibiofibular clear space (TFCS), tibiofibular overlap (TFO), and medial clear space (MCS). A subgroup analysis for each demographic group and injury type including pure syndesmosis injury, Weber-B, and Weber-C type fractures were performed. Results Syndesmosis was effectively reduced using TightRope. After the index surgery, the tibiofibular clear space was reduced from 7.73 to 4.04 mm, the tibiofibular overlap was increased from 3.05 to 6.44 mm, and the medial clear space was reduced from 8.12 to 3.54 mm. However, syndesmosis widening was noted at the final follow-up, especially in Weber-C type fractures (TFCS 3.82 to 4.45 mm, p < 0.01 and TFO 6.86 to 6.29 mm, p = 0.04). Though widened, the final follow-up values of tibiofibular clear space and tibiofibular overlap were in the acceptable range. Postoperatively and at the final follow-up, medial clear space was found to be significantly larger in the Weber-C group than in the pure syndesmosis and Weber-B groups (p < 0.05). Conclusions Suture-button fixation can offer anatomic reduction and dynamic fixation in syndesmosis injuries. However, when using this modality for Weber-C type fractures, more attention should be focused on the accuracy of reduction, especially of medial clear space, and rediastasis should be carefully monitored. Trial registration This trial was retrospectively approved by TMU-JIRB. Registration number N202004122, and the date of approval was May 06, 2020. Level of evidence III

Screw Breakage

Category: Ankle Introduction/Purpose: Syndesmotic disruption occurs in nearly 1 in 5 ankle fractures and requires anatomic reduction and internal stabilization to maximize functional outcomes. There is growing evidence to support retaining syndesmotic hardware from both a functional and economic standpoint. However, although broken screws are typically of little consequence, the location of screw breakage can be unpredictable and cause painful bony erosion and difficulty with extraction. The purpose of this investigation is to report early clinical and radiographic outcomes of patients who underwent syndesmotic fixation using a novel metal screw with a more predictable break point and design features to allow for easier extraction. Methods: We performed a retrospective review of all consecutive patients who underwent syndesmotic fixation utilizing the novel syndesmotic screw over a one year period. Demographic data were obtained such as age, gender, fracture classification and relevant comorbidities. Screw specific data were obtained such as number of screws utilized and length. Screw loosening or breakage was documented. Postoperative radiographs were reviewed and tibiofibular overlap, tibiofibular clear space and medial clear space were measured. Results: 18 patients met inclusion criteria. Mean length of clinical follow-up was 4.67 months (range 0.5 to 8.5 months). Per the Lauge Hansen classification, 14 injuries were supination external rotation type, two were pronation abduction and two pronation external rotation type. Three screws (12.5%) fractured at the break point with no screws fracturing at a different location. 21 screws did not fracture with 10 (42%) of the screws demonstrated to be loose. There was no evidence of syndesmotic diastasis or mortise malalignment on final follow up of the cohort. No screws required removal during the study period. There were no other complications of any type (Table 1). Conclusion: Early reporting of outcomes is essential to maximize both safety and value in healthcare technology innovation. This study provides the first clinical data on a novel alternative to traditional screws and suture button devices for fixation of syndesmotic injuries. At short-term follow up, there were no complications and the novel screw provided adequate fixation to allow healing and prevent diastasis. While initial results are favorable, longer term follow-up is required to determine whether this novel implant can reduce rates of symptomatic hardware requiring removal, which could ultimately make them more cost- effective than suture-button fixation.

Background: Tightrope fixation is an emerging technique for syndesmotic fixation with promising results. However, our case series highlights the slippage of Tightrope buttons as a complication of suture button syndesmotic fixation of Weber C malleolar fractures using limited contact dynamic compression (LCDCP) plates. Methods: We report a series of cases from our database in which slippage of the Tightrope button through the LCDCP holes in Weber C malleolar fractures was noted. We measured the medial clear space (MCS), tibiofibular clear space (TFCS), and distal tibiofibular overlap (DTFO) and computed the largest change in these measurements from the first postoperative follow-up radiographs. Patient records were reviewed for persistent symptoms that could be attributed to the loss of syndesmotic fixation and stability. Results: Follow-up radiographs of 3 patients showed a slippage of the Tightrope button through the LCDCP holes. Two of the patients reported persistent ankle pain and swelling with prolonged activity. The mean increases in MCS and TFCS among these patients were 0.7 (±0.081) mm and 1.5 (±0.798) mm, respectively. The mean decrease in DTFO was 2.2 (±0.864) mm. We next highlight 3 patients with Weber C malleolar fractures who underwent suture button syndesmotic fixation using double-stacked one-third tubular plates instead of the LCDCP. Conclusion: This case series reported Tightrope button slippage as an early complication of syndesmotic fixation of Weber C malleolar fractures. We propose the use of double-stacked one-third tubular plates instead of the LCDCP to avoid this complication. Level of Evidence: Level V, expert opinion.

Background: Some studies have advocated the use of suture-button fixation during the Latarjet procedure to reduce complications associated with screw fixation. However, the sample size of these studies is relatively small, and their follow-up period is short. Purpose: To investigate the efficacy of the suture-button Latarjet procedure with at least 3 years of follow-up and remodeling of the coracoid graft. Study Design: Case series; Level of evidence, 4. Methods: A total of 152 patients who underwent the suture-button Latarjet procedure between February 2013 and February 2016 were selected, and 128 patients who met the inclusion criteria were enrolled in this study. Preoperative and postoperative clinical results were assessed. The position and healing condition of the coracoid graft and arthropathy of the glenoid and humeral head were also assessed using radiography and 3-dimensional computed tomography (CT). Results: The mean follow-up time was 40.3 ± 5.8 months. There were 102 patients included in this study. The mean visual analog scale score for pain during motion, the American Shoulder and Elbow Surgeons score, the Rowe score, and the Walch-Duplay score were improved considerably. A total of 100 grafts achieved bone union. The overall absorption rate was 12.6% ± 4.3%. Graft absorption mostly occurred on the edge and outside the “best-fit” circle of the glenoid. A vertical position was achieved in 98 grafts (96% of all cases) immediately postoperatively, with the mean graft midline center at the 4 o’clock position. In the axial view, CT showed that 89 grafts were flush to the glenoid, whereas 2 and 11 grafts were fixed medially and laterally, respectively. In all cases, the bone graft and glenoid tended to extend toward each other to form concentric circles during the remodeling process. During follow-up observations, the height of the 11 grafts that were positioned laterally (ie, above the glenoid level) exhibited a wave-curved change. No arthropathy was observed in any patient. Conclusion: Patient outcomes were satisfactory after the modified arthroscopic suture-button Latarjet technique. Graft absorption mostly occurred on the edge and outside the “best-fit” circle of the glenoid. The graft exhibited the phenomenon of ectatic growing when it fused with the glenoid and finally remodeled to a new concentric circle with the humeral head analogous to the original glenoid. Grafts positioned laterally did not cause arthropathy of the joints within the period of the study.

Background: Among the most important predictors of functional results of treatment of syndesmotic injuries is the accurate restoration of the syndesmotic space. The purpose of this study was to investigate the reduction performance of screw fixation and suture-button techniques using images obtained from computed tomography (CT) scans. Methods: Patients at or below 65 years who were treated with screw or suture-button fixation for syndesmotic injuries accompanying ankle fractures between January 2012 and March 2015 were retrospectively reviewed in our regional trauma unit. A total of 52 patients were included in the present study. Fixation was performed with syndesmotic screws in 26 patients and suture-button fixation in 26 patients. The patients were divided into 2 groups according to the fixation methods. Postoperative CT scans were used for radiologic evaluation. Four parameters (anteroposterior reduction, rotational reduction, the cross-sectional syndesmotic area, and the distal tibiofibular volumes) were taken into consideration for the radiologic assessment. Functional evaluation of patients was done using the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale at the final follow-up. The mean follow-up period was 16.7 ± 11.0 months, and the mean age was 44.1 ± 13.2. Results: There was a statistically significant decrease in the degree of fibular rotation ( P = .03) and an increase in the upper syndesmotic area ( P = .006) compared with the contralateral limb in the screw fixation group. In the suture-button fixation group, there was a statistically significant increase in the lower syndesmotic area ( P = .02) and distal tibiofibular volumes ( P = .04) compared with the contralateral limbs. The mean AOFAS scores were 88.4 ± 9.2 and 86.1 ± 14.0 in the suture-button fixation and screw fixation group, respectively. There was no statistically significant difference in the functional ankle joint scores between the groups. Conclusion: Although the functional outcomes were similar, the restoration of the fibular rotation in the treatment of syndesmotic injuries by screw fixation was troublesome and the volume of the distal tibiofibular space increased with the suture-button fixation technique. Level of Evidence: Level III, retrospective comparative study.

Background: The suture anchors for the repair of deltoid ligament in rotational ankle fracture are inserted mostly into the medial malleolus, but sometimes are placed into the talus depending on the rupture site. This study sought to compare the radiological and clinical outcomes of deltoid ligament repair according to using these 2 locations for suture anchor placement. Methods: The cases of 131 patients (114 patients with suture anchors on the medial malleolus and 17 patients with suture anchors on the talus) who underwent deltoid ligament repair along with ankle fracture fixation were retrospectively reviewed. Medial clear space oblique (MCSo), medial clear space perpendicular (MCSp), tibiofibular clear space (TFCS), and tibiofibular overlap (TFO) were measured as radiological outcomes, while the Olerud-Molander Ankle Score (OMAS) and visual analog scale (VAS) score for pain were calculated as clinical outcomes. The follow-up period did not differ between the 2 groups (16.8 ± 10.9 months in the medial malleolus group vs 17.9 ± 14.3 months in the talus group; P = .670). Results: There were no differences in MCSo, MCSp, TFCS, and TFO at 3 months after surgery and final follow-up. The OMAS and VAS for pain did not show intergroup differences at final follow-up. Conclusion: The surgical outcome of deltoid ligament repair in rotational ankle fracture did not differ whether the suture anchors were inserted into the medial malleolus or into the talus. Level of Evidence: Level III, retrospective comparative study.

Category: Trauma Introduction/Purpose: Suture-button fixation device (TightRope, Arthrex, Naples, Florida) is devised to obviate the need for second operation for removal in the treatment of syndesmosis diastasis, but considerable removal rate has been reported. Nevertheless, functional and radiographic outcomes after suture-button fixation device removal has not yet been well documented. Therefore, the purpose of this study is to investigate the functional and radiographic outcomes of syndesmosis fixation treated with suture-button device before and after device removal. Methods: The records of 30 patients with syndesmosis injury who underwent suture-button fixation and later device removal between August 2009 and September 2017 were investigated. The mean postoperative time to device removal was 11.9 months (range, 7-19). In plain radiograph, tibiofibula clear space (TFCS), tibiofibula overlap (TFO), and medial clear space (MCS) were measured at three specific follow-up period; immediate postoperative (F1), just before device removal (F2), and at least three months after device removal (F3). For subgroup of 18 patients with CT scans, the Anterior to posterior (A/P) ratio (Normal range: 0.8 -1.2) was measured to investigate malreduction of syndesmosis and they were divided into two groups according to their accuracy of reduction. Additionally, functional outcomes were recorded and compared using American Orthopedic Foot and Ankle (AOFAS) score. Repeated measurement analysis of variance was performed to statistically compare the data and statistical significance was set at P < 0.05. Results: In plain radiographs, TFCS, TFO, MCS at three specific follow-up period showed no significant differences. In CT analysis at immediate postoperative period, 6 cases (30%) revealed malreduction, but 5 of them showed spontaneous reduction at follow- up just before device removal. Malreduced patients (n = 6) had a mean A/P ratio of 1.28 (range, 0.78 -1.52) at F1, 1.08 (range, 0.81- 1.21) at F2, and 1.08 (range, 0.83 -1.22) at F3 (F1, F2: p = 0.021, F1, F3: p = 0.032, F2, F3: p > 0.05). Patients with initial adequate reduction (n = 12) continued to have a reduced syndesmosis during the follow-up period and after the device removal. The AOFAS score did not change significantly before and after removal. Conclusion: Our investigation showed that the removal of suture-button device for syndesmosis fixation at average 1-year postoperative time does not bring out reduction loss or functional changes. Thus, removal is advisable for the patients with irritation or discomfort related to device. Furthermore, malreduced syndesmosis after tightrope fixation may have possibility of spontaneous reduction during the follow-up period.

AbstractThis case-series outcome study presents a new arthroscopic technique for tibial eminence avulsion fracture (TEAF) with double-tunnel using two tightrope suture buttons. From May 2017 to July 2020, we performed a new arthroscopic technique for TEAF with double tunnels, using two tightrope suture buttons on 13 patients. Clinical assessments included anterior drawer, Lachman, and pivot shift tests, the International Knee Documentation Committee (IKDC), Lysholm knee scores, visual analog scale (VAS) scores, and range of motion (ROM). An independent observer noted conditions before surgery and during the last follow-up. The patients had an average follow-up of 26.2 months, ranging from 15 to 37 months. During the last postsurgical follow-up, the anterior drawer, Lachman, and pivot shift tests were negative in all the cases. According to the IKDC, Lysholm, and VAS final scores, all patients presented a significant knee function improvement at last follow-ups compared with preoperatively. The study shows that satisfactory results about an anatomic reduction of the fragment, knee stability, function, and strength can be achieved with the new arthroscopic technique for TEAF with double tunnels using two tightrope suture buttons. This study is a therapeutic case series and its level of evidence is IV.
