Abstract
BACKGROUND Studies routinely evaluate high ankle sprains in isolation, but recent data suggest that these injuries are often associated with concomitant pathology, potentially influencing return to full participation. HYPOTHESIS In National Football League (NFL) players, isolated high ankle sprains are rare and syndesmosis injuries with concomitant pathology will result in increased time to return to full participation. STUDY DESIGN Cross-sectional study. LEVEL OF EVIDENCE Level 3. METHODS Distal tibiofibular syndesmosis injuries sustained by NFL players between 2017 and 2019 were identified through NFL Injury Surveillance Database queries and verified with video analysis. Each injury underwent a comprehensive magnetic resonance imaging (MRI) review. Regression modeling was utilized to explore the influence of numerous imaging findings on time to return to full participation. RESULTS There were 83 external rotation ankle injuries involving the syndesmosis. Isolated distal tibiofibular syndesmosis injuries were rare (n = 11; 13%) and more often associated with other ligamentous injury (deltoid ligament and lateral ligamentous complex) and/or fractures. Regression modeling resulted in clustering of 3 injury pattern groups for time to return to full participation across numerous imaging findings: syndesmosis injury-fracture combinations (250 days [interquartile range [IQR,] 142-266 days]), syndesmosis injury with complete deep deltoid tear or acute diastasis (175 days [IQR, 20-248 days]), and all other syndesmosis injuries (27 days [IQR, 18-46 days]). CONCLUSION In NFL athletes with external rotation ankle injuries, isolated distal tibiofibular syndesmosis injuries were rare and more often associated with concomitant pathology. Time to return to full participation was affected by an associated fracture and complete deep deltoid ligament tear or diastasis but no other relevant MRI variables such as lateral ligament complex involvement or the presence of osteochondral lesions or bone contusions.

[PMID: 38303073 PMCID: PMC10835897 DOI: 10.1186/s13643-023-02448-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 12/28/2023] [Indexed: 02/03/2024] Open
Abstract
OBJECTIVE The objective of this study was to conduct a meta-analysis by synthesizing multiple literature sources to explore whether there are any differences between elastic fixation and rigid fixation in the treatment of acute tibiofibular syndesmosis injuries. The aim was to provide effective guidance for clinical treatment. METHODS We conducted a comprehensive search across seven databases, including both Chinese and English, to include all studies related to the treatment of acute tibiofibular syndesmosis injuries with elastic fixation and rigid fixation published between January 1, 2013, and November 15, 2022. Following the PRISMA guidelines, we rigorously screened, assessed, and extracted data from the included studies. The outcome measures included AOFAS scores at 3, 6, and 12 months postoperatively; tibiofibular clear space (TBCS) and tibiofibular overlap distance (TBOL) at the early postoperative and 12-month follow-up; intraoperative blood loss; operative time; time to full weight-bearing postoperatively; and postoperative complications. Meta-analysis was performed using Review Manager 5.4. RESULTS A total of 35 studies were included, comprising 16 randomized controlled trials and 19 retrospective cohort studies. The study population included 2120 cases, with 1044 cases in the elastic fixation group and 1076 cases in the rigid fixation group. The elastic fixation group had higher AOFAS scores at 3, 6, and 12 months postoperatively compared to the rigid fixation group. Although the elastic fixation group had a slightly larger TBCS than the rigid fixation group in the early postoperative period, the difference between the two groups became statistically insignificant at 12 months postoperatively. There was no statistically significant difference in TBOL between the two groups in the early postoperative period, but at 12 months, the elastic fixation group had a greater TBOL than the rigid fixation group. Additionally, the elastic fixation group had lower rates of postoperative local irritation, wound infection, and postoperative internal fixation loosening or rupture compared to the rigid fixation group. The rate of postoperative tibiofibular redislocation did not differ statistically between the two groups. The time to full weight-bearing was shorter in the elastic fixation group than in the rigid fixation group. Although the elastic fixation group had a slightly longer operative time, there was no statistically significant difference in intraoperative blood loss between the two groups. CONCLUSION Compared to rigid fixation, elastic fixation in the treatment of acute tibiofibular syndesmosis injuries offers several advantages, including better postoperative ankle joint function recovery, more precise anatomical reduction of the syndesmosis postoperatively, a lower incidence of postoperative complications, and shorter time to full weight-bearing postoperatively. These findings provide robust guidance for clinical treatment.

Abstract
The distal tibiofibular syndesmosis (DTFS) is more frequently injured than previously thought. Early diagnosis and appropriate treatment is essential to avoid long term complications like chronic instability, early osteoarthritis and residual pain. Management of these injuries require a complete understanding of the anatomy of DTFS, and the role played by the ligaments stabilizing the DTFS and ankle. High index of suspicion, appreciating the areas of focal tenderness and utilizing the provocative maneuvers help in early diagnosis. In pure ligamentous injuries radiographs with stress of weight bearing help to detect subtle instability. If these images are inconclusive, then further imaging with MRI, CT scan, stress examination under anesthesia, and arthroscopic examination facilitate diagnosis. An injury to syndesmosis frequently accompanies rotational fractures and all ankle fractures need to be stressed intra-operatively under fluoroscopy after fixation of the osseous components to detect syndesmotic instability. Non-operative treatment is appropriate for stable injuries. Unstable injuries should be treated operatively. Anatomic reduction of the syndesmosis is critical, and currently both trans-syndesmotic screws and suture button fixation are commonly used for syndesmotic stabilization. Chronic syndesmotic instability (CSI) requires debridement of syndesmosis, restoration of ankle mortise with or without syndesmotic stabilization. Arthrodesis of ankle is used a last resort in the presence of significant ankle arthritis. This article reviews anatomy and biomechanics of the syndesmosis, the mechanism of pure ligamentous injury and injury associated with ankle fractures, clinical, radiological and arthroscopic diagnosis and surgical treatment.

Abstract
Despite its clinical relevance in the context of ankle fractures, little is known about the bone microarchitecture and strength of the distal fibula, especially regarding age-, sex-, and subregion-specific effects. To address this gap of knowledge, we obtained fibulae from 30 skeletally intact donors at autopsy (each 15 male and female), which were analyzed by high-resolution peripheral quantitative computed tomography including micro-finite element analysis. Scans were performed in a 7-cm volume of interest and evaluated in three subregions according to the Danis-Weber fracture classification. Group comparisons and linear regression analyses were applied to evaluate the effects of age, sex, and subregion. From distal to proximal, we observed an increase of cortical parameters and a decrease of trabecular parameters. Age was primarily associated with a cortical decrease in all subregions (Danis-Weber type A, B, and C) in women. While women showed a greater magnitude of decline, men also exhibited an age-associated decrease for some parameters, including cortical area and cortical thickness in the type C subregion. Stiffness and failure load were highest in the type C subregion in both women and men. A critical age-related decline in bone strength parameters in the type B subregion was observed in women, providing an explanation for the increased incidence of low-traumatic type B fractures in the elderly. Together, these findings extend the current understanding of distal fibular microarchitecture, likely explaining the epidemiologic features of distal fibula fractures and emphasizing the need for age-adapted treatment algorithms.

Abstract
Injuries of the ankle ligaments complexes are very common, and ∼ 20 to 40% of patients can develop chronic ankle instability (CAI). Current concepts in CAI allow a better understanding of the ankle biomechanics needed to repair it. The surgical treatment of CAI has evolved in the last decade, and ankle arthroscopy has become an essential tool in the treatment of instability with promising results. We review the different surgical techniques to treat CAI, both those frequently used and the new approaches, as well as the normal postsurgical appearance of ankle ligaments repair and the most common complications.

Abstract
BACKGROUND The optimal surgical management of syndesmosis injuries consists of internal fixation between the distal fibula and tibia. Much of the available data on this joint details the anatomy of the syndesmotic ligaments. Little is published evaluating the distribution of articular cartilage of the syndesmosis, which is of importance to minimize the risk of iatrogenic damage during surgical treatment. The purpose of this study is to describe the articular cartilage of the syndesmosis. METHODS Twenty cadaveric ankles were dissected to identify the cartilage of the syndesmosis. Digital images of the articular cartilage were taken and measured using calibrated digital imaging software. RESULTS On the tibial side, distinct articular cartilage extending above the plafond was identified in 19/20 (95%) specimens. The tibial cartilage extended a mean of 6 ± 3 (range, 2-13) mm above the plafond. On the fibular side, 6/20 (30%) specimens demonstrated cartilage proximal to the talar facet, which extended a mean of 24 ± 4 (range, 20-31) mm above the tip of the fibula. The superior extent of the syndesmotic recess was a mean of 10 ± 3 (range, 5-17) mm in height. In all specimens, the syndesmosis cartilage did not extend more than 13 mm proximal to the tibial plafond and the syndesmotic recess did not extend more than 17 mm proximal to the tibial plafond. CONCLUSION Syndesmosis fixation placed more than 13 mm proximal to the tibial plafond would have safely avoided the articular cartilage in all specimens and the synovial-lined syndesmotic recess in most. CLINICAL RELEVANCE This study details the articular anatomy of the distal tibiofibular joint and provides measurements that can guide implant placement during syndesmotic fixation to minimize the risk of iatrogenic cartilage damage.

Abstract
STUDY DESIGN Case Series. BACKGROUND Syndesmotic ankle sprains can occur in up to 17% of ankle trauma and can lead to long-term disability. This study describes the management of seven patients with subacute, high-grade ankle sprains with concerns of concurrent syndesmotic strain utilizing manual therapy and rigid sports taping. METHODS Seven active duty military members with clinically diagnosed, high-grade ankle sprains and concern for syndesmotic sprain participated in this case series. All patients received multi-modal treatment consisting of manual therapy, rigid sports taping, progressive exercises, and proprioceptive training. Decrease in Numeric Pain Rating Scale (NPRS) following manual therapy and taping treatment, number of sessions before discharge, and the Global Rating of Change (GROC) at discharge were retrospectively reviewed. RESULTS All patients demonstrated an immediate decrease in NPRS following treatment on average of 5 points (range, 3-8 points) with a functional asterisk sign. The improvement in pain and function was maintained until the next treatment session with a mean GROC score of +3. The mean time until recovery was 5.4 weeks (range, 1-8 weeks). DISCUSSION A multimodal approach for patients diagnosed clinically with high-grade ankle sprains and concern for syndesmotic sprain was useful to immediately reduce pain and improve function, and improvements were maintained throughout the duration of care. This study is the first to assess a combination of manual therapy and rigid sports taping for the treatment of suspected syndesmotic ankle sprains, and more stringent research is needed to validate the findings.

Abstract
An optimal outcome of surgical treatment for a syndesmotic injury depends on accurate reduction and adequate fixation. It has been suggested that the use of a reduction clamp for reduction of the syndesmosis results in better reduction and a lower rate of redisplacement than manual reduction. However, these concepts have never been scientifically evaluated. We compared these 2 methods in a prospective randomized trial. A total of 85 acute ankle rotational fractures combined with syndesmotic injury were randomized to syndesmosis reduction with either a reduction clamp or manual manipulation. Reduction of the syndesmosis was assessed radiographically by measuring the tibiofibular clear space, tibiofibular overlap, and the medial clear space immediately postoperatively and at the final follow-up examination. Ankle joint range of motion, visual analog scale score, Olerud-Molander ankle scoring system, and complications were obtained at the last follow-up visit to assess the clinical outcomes. Of the 3 radiographic measurements, the tibiofibular clear space and tibiofibular overlap differed significantly between the 2 groups (p < .05). The clinical outcomes did not differ significantly between the 2 groups (p > .05). Although differences were found in the radiographic measurements, most syndesmoses in both groups were within the normal range at the final follow-up visit, and the 2 methods of syndesmosis reduction provided similar clinical outcomes. Accordingly, the results of the present study suggest that both of these methods are effective and reliable for reduction of the syndesmosis in rotational ankle fractures.

Abstract
OBJECTIVES To evaluate the cost effectiveness of suture buttons compared with syndesmotic screws for repair of tibiofibular syndesmotic injuries. METHODS A decision tree model was constructed to describe outcomes after syndesmosis repair using suture buttons and syndesmotic screws from the perspective of a capitated health care system. Outcomes were uneventful healing, removal of symptomatic implants, deep infection, and persistent diastasis requiring revision. Weighted literature averages were used to estimate variables for a baseline model. Outcomes were measured in quality adjusted life years. Procedure and implant costs were derived from Medicare reimbursement rates and the University Health System Consortium. An incremental cost-effectiveness ratio threshold of $50,000 per quality-adjusted life years was used to evaluate cost effectiveness. RESULTS The baseline model did not identify suture buttons to be cost effective. Sensitivity analysis demonstrates the model to be exquisitely sensitive to small changes in reoperation rates and implant price. At median University Health System Consortium implant prices, if the removal rate for symptomatic screws is below 13.7%, then screws are cost effective. If the screw removal rate is greater than 17.5%, then a suture button is cost effective. Within this interval, detailed analysis of the model suggests that screws may be the cost-effective strategy, but that determination should be taken with caution. CONCLUSIONS Moving away from the practice of routinely removing all syndesmotic screws has changed the financial landscape of syndesmosis repair. At their median cost, suture buttons are likely to be cost effective over screws for symptomatic screw removal rates greater than 17.5%. Cost effectiveness is sensitive to changes in implant removal rates and the number of devices used per patient. LEVEL OF EVIDENCE Economic Level IV.

Abstract
The syndesmosis is important for ankle stability and load transmission and is commonly injured in association with ankle sprains and fractures. Syndesmotic disruption is associated with between 5 and 10% of ankle sprains and 11-20% of operative ankle fractures. Failure to recognize and appropriately treat syndesmotic disruption can portend poor functional outcomes for patients; therefore, early recognition and appropriate treatment are critical. Syndesmotic injuries are difficult to diagnose, and even when identified and treated, a slightly malreduced syndesmosis can lead to joint destruction and poor functional outcomes. This review will discuss the relevant anatomy, biomechanics, mechanism of injury, clinical evaluation, and treatment of acute injuries to the ankle syndesmosis.
