Correlation between Ankle Imaging Findings and Self-Reported Outcomes: A Longitudinal Assessment in Patients with Tibiofibular Diastasis.

BACKGROUND AND OBJECTIVES: This longitudinal study investigated the correlation between imaging findings and self-reported questionnaire outcomes in patients with tibiofibular diastasis, exploring the effects of surgical screw removal versus conservative treatment. This study was conducted at "Victor Babes" University of Medicine and Pharmacy in Timisoara between 2018 and 2023. MATERIALS AND METHODS: The study involved 85 patients in the screw removal group and 44 in the conservative group, assessed at 2 and 6 months post-surgery, answering the SF-36, HADS, and WHOQOL questionnaires. RESULTS: Significant differences were observed at 2 months post-surgery, with the screw removal group showing lower shear wave velocities in ankle dorsiflexion (8.9 ± 1.4) and anterior talofibular ligament (2.8 ± 0.9), indicating better mobility compared to the conservative group (ankle dorsiflexion: 10.1 ± 1.8, ATFL: 3.2 ± 1.1). Radiographically, lower tibiofibular overlap (8.1 ± 2.1) in the screw removal group suggested improved joint fixation quality. These physical improvements were mirrored in the quality-of-life assessments, where the screw removal group reported higher physical health scores on the SF-36 survey at 2 months, a trend that continued at 6 months. At 2 months, ankle dorsiflexion demonstrated a strong negative correlation with the SF-36 Physical score (r = -0.417) and WHOQOL Physical domain (r = -0.394), and a positive correlation with HADS Anxiety (r = 0.312). Similarly, ATFL and CFL velocities negatively correlated with the SF-36 Physical score (ATFL: r = -0.251; CFL: r = -0.237). Radiographic tibiofibular overlap and clear space positively correlated with WHOQOL Physical domain (TOL: r = 0.291; TCS: r = 0.276), with TCS also negatively correlating with HADS Anxiety (r = -0.228). At 6 months, these correlations persisted, with notable negative correlations between ultrasound ankle dorsiflexion and both SF-36 Physical score and WHOQOL Physical domain. CONCLUSIONS: These findings underscore the advantages of screw removal in enhancing physical recovery and reducing anxiety in the short term, while indicating similar long-term mental health outcomes between treatment approaches.

Impact of Syndesmotic Screw Removal on Quality of Life, Mobility, and Daily Living Activities in Patients Post Distal Tibiofibular Diastasis Repair.

Background and Objectives: While numerous studies have been conducted on syndesmotic screw management following distal tibiofibular diastasis repair, a clear consensus remains unclear. This research aims to evaluate whether the postoperative removal of syndesmotic screws leads to improved patient outcomes, specifically in quality of life, mobility, and daily living activities, and whether it offers a cost-effective solution. Materials and Methods: Patients with a history of unimalleolar or bimalleolar ankle fractures, classified according to the Danis-Weber and Lauge-Hansen systems, were included. Comprehensive evaluations were made via standardized questionnaires like the SF-36 Health Survey, HADS, and WHOQOL-BREF, distributed approximately 2 months post surgery. A total of 93 patients underwent syndesmotic screw removal while 51 retained the screws (conservative approach). Results: Patients who underwent screw removal reported superior satisfaction in mobility, with a score of 7.8, compared to 6.7 in the conservative approach (p = 0.018). Similarly, their ability to perform daily activities scored 8.1, higher than the 6.5 from the conservative cohort (p < 0.001). Pain levels were also more favorable in the screw removal group, with a score of 5.3 against 6.8 in the conservative group (p = 0.003). On the SF-36 physical domain, the screw removal group achieved a mean score of 55.9 versus 53.3 for the conservative group (p = 0.027). Notably, the HADS anxiety subscale highlighted reduced anxiety levels in the screw removal cohort with a mean score of 5.8 against 7.3 in the conservative group (p = 0.006). However, overall quality of life and recommendations to others showed no significant difference between the groups. Conclusions: Syndesmotic screw removal postoperatively leads to marked improvements in patients' mobility, daily activity abilities, and reduced postoperative pain and anxiety levels. However, overall quality of life was similar between the two approaches. The findings offer valuable insights for orthopedic decision making and patient-centered care concerning the management of syndesmotic screws after distal tibiofibular diastasis repair.

Avoiding the Removal of Syndesmotic Screws after Distal Tibiofibular Diastasis Repair: A Benefit or a Drawback?

There is still no general agreement about the most effective form of syndesmosis fixation with syndesmotic screws for patients affected by ankle fractures that are accompanied by syndesmotic injuries. In the same manner, no consensus has been reached yet on whether or not the tibiofibular syndesmotic screw is more beneficial if removed or not, as well as the exact timing of removal if this proves superiority. The purpose of this research was to verify whether or not removing syndesmotic screws reduces the risk of developing a diastasis and compare outcomes in patients whose syndesmotic screw was or was not removed at all. A retrospective observational study was carried out to cover a period of five years and a computed sample size of almost 300 cases. Patients were included in the current study if their history was positive for ankle fracture with distal tibiofibular diastasis repair with syndesmotic screws. Loss of reduction was more frequent after screw removal (8.5% vs. 2.1%), although the quality of reduction was generally excellent in both groups. The mean AOFAS score was significantly better in patients who had their tibiofibular screw removed (92.6 vs. 88.4), but the tibiofibular clear space and incisura fibularis depth widened more following the second intervention (3.8 mm vs. 3.6 mm, and, respectively, 4.3 vs. 4.1). Lastly, the same patients with tibiofibular screw removal had a significantly higher cost of total interventions and more days of medical leave (21 vs. 15 days on average). It seems that a strong conclusion in favor of removing or not removing syndesmotic screws after distal tibiofibular diastasis repair cannot be given. However, several radiographic findings lean toward the benefit of those patients whose tibiofibular screws were not removed, although mobility was notably better after the screw was removed. Furthermore, treatment expenses are greatly lowered if a subsequent operation for screw removal is avoided, as well as if individuals who have a single surgery take a shorter medical leave.
