Radiographic Assessment of Tibiofibular Syndesmosis Injury with Different Durations and Types of Fixation.

INTRODUCTION: There is no consensus among orthopedic surgeons on the number of cortical layers (tricortical or quadricortical fixation) involved or the duration of syndesmotic fixation after a tibiofibular syndesmosis (TFSD)-injury treatment. The purpose of this study was to assess radiographic parameters following the treatment of TFSD injuries, with various time-windows of syndesmotic screw removal and numbers of cortical layers involved. MATERIALS AND METHODS: Fifty-five patients, aged from 25 to 75 years, were included in the study. The follow-up period ranged from 2 years to 4 years and 2 months. The patients were subdivided into groups based on the duration of the syndesmotic fixation (8-15 weeks-19 patients or 16-22 weeks-36 patients) and the number of cortices involved (tricortical-17 patients or quadricortical fixation-38 patients). RESULTS: The quadricortical fixation group showed a significant development of ankle joint arthritis and subtalar joint arthritis at the final follow-up. The mean medial clear space was 2.84 mm in the tricortical fixation group and 3.5 mm in the quadricortical fixation group (p = 0.005). Both groups, with different screw removal times showed significant development of posttraumatic arthritis. A comparison of the two groups (with different time-windows of the screw removal) revealed a significant difference only in terms of the postoperative tibiofibular (TF) overlap and the observed rates of talonavicular arthritis at the final follow-up. DISCUSSION: We found that the duration of the screw fixation had no effect on most of the evaluated radiographic parameters. Only the postoperative TF overlap was lower in the 8-15-week fixation group, and the proportion of patients with talonavicular joint arthritis at the final follow-up was higher in the 16-22-week fixation group. In addition, the number of cortices involved in the screw fixation had no effect on the radiographic outcomes in our patients, apart from the differences in one parameter-the medial clear space-at the final follow-up. CONCLUSION: We achieved similar radiographic results irrespective of the duration of the screw fixation and the number of cortices involved. All study subgroups showed the development of adjacent-joint arthritis following treatment. Considering the results of our study, the economic and medical aspects of treatment, and the possibility of a faster recovery, the most optimal solution seems to be the use of a tricortical fixation, with the screws being removed after 8-15 weeks.

Adapting an evidence-supported optimization program for mental health and sport performance in collegiate athletes to fit youth from ethnic/racial minority and low-income neighborhoods: A National Institutes of Health stage model feasibility study.

The current study addresses the need to empirically develop effective mental health interventions for youth from ethnic/racial minority and low-income neighborhoods. Using Stage Model evaluation methods supported by the National Institutes of Health in the US to address underutilization of mental healthcare among racial/ethnic minority youth, this feasibility study demonstrates empirical adaptation of an innovative sport-specific psychological intervention for use in youth from ethnic/racial minority and low-income neighborhoods. An international group of professionals familiar with sport performance and mental health intervention serving the target population experientially examined the adapted intervention protocols in workshops and provided feedback. Survey results indicated the professionals found the intervention components were easy to administer and likely to be safe, enjoyable, engaging and efficacious for youth mental health and sport performance. The protocols were revised based on feedback from these professionals and the intervention was examined in a case trial involving an Asian American youth who evidenced Social Anxiety Disorder. Case study results indicated the intervention could be implemented with integrity, and severity of psychiatric symptoms and factors interfering with sport performance decreased after intervention implementation. The participant's relationships with family, coaches and teammates were also improved.

Assessment of the lower limb biomechanics in patients after tibiofibular syndesmosis injury treatment.

PURPOSE: There is no consensus as to the number of bone cortices engaged in tibiofibular syndesmosis treatment. The purpose of our study was to assess the weight distribution on the lower limbs after tricortical or quadricortical syndesmosis fixation and different timing of screw removal. METHODS: A total of 55 patients who underwent treatment for acute tibiofibular syndesmosis injury were analyzed in this study. The Zebris pedobarographic platform was used to measure the distribution of body weight on the lower limbs. The study population was stratified by the time to syndesmotic screw removal (8-15 weeks versus 16-22 weeks) and the number of bone cortices involved in fixation (three [tricortical fixation] versus four [quadricortical fixation]). RESULTS: The weight distribution on the operated and healthy limbs in patients with tricortical syndesmosis fixation was asymmetrical, with the mean load on the operated and healthy limbs of 48.38% and 51.62%, respectively. The patients who underwent quadricortical syndesmosis fixation exhibited a symmetrical distribution of weight on the operated and healthy limb. There was a symmetrical distribution of the load of body weight on the operated and healthy limbs both in the group with different times to syndesmotic screw removal. CONCLUSION: Tricortical syndesmosis fixation is associated with an asymmetrical weight distribution on the operated and healthy limbs. In treating tibiofibular syndesmosis injuries, based on our pedobarographic research, quadricortical syndesmosis fixation and leaving the syndesmotic screw in place for up to 15 weeks, seems more beneficial to the patient.
