Ankle Ligament Injuries Based on Medical Images of Hip-Hop Training and Research on Training Techniques

Ligament loss of the ankle joints is common. If it is not handled properly, it is easy to cause repeated sprains of the ankle joints. Usually, medical image examination will be the first choice for the diagnosis of ligament injury. This paper analyzes the ankle ligament injury of hip-hop training based on medical images and studies the hip-hop training skills, to explore the application method of medical images in ankle injury, and can provide some theoretical and practical references for other sports injuries. In this paper, several medical image-related technologies such as texture feature extraction, main visual feature SAR method, and edge detection method are proposed. These technologies are applied to the study of ankle ligament injury, and an effective medical training therapy is determined by setting up the control group and the treatment group to observe the medical image display of each part of the ankle. Through the statistics of the clinical efficacy judgment standard results of patients in the treatment group and patients in the control group after two weeks of injury, it is found that the experimental results show that the cure rate, significant efficiency, and total effective rate of patients in the treatment group after two weeks are higher than those in the control group, and the total effective rate of the treatment group has reached 92.20%.

Incidence and risk factors for poor ankle functional recovery, and the development and progression of posttraumatic ankle osteoarthritis after significant ankle ligament injury (SALI): the SALI cohort study protocol

Background Ankle sprains are one of the most common musculoskeletal injuries, accounting for up to 5% of all Emergency Department visits in the United Kingdom. Ankle injury may be associated with future ankle osteoarthritis. Up to 70% of ankle osteoarthritis cases may be associated with previous ankle injury. There is limited research regarding the association between ankle sprain and ankle osteoarthritis development. The current study aims to phenotype those who suffer significant ankle ligament injuries, identify potential risk factors for ankle injuries and subsequent poor recovery, examine why individuals may develop osteoarthritis, and what factors influence this chance. Methods In this multicentre cohort study participants were recruited from nine Emergency Departments and two Urgent Care Centres in the United Kingdom. Participants (aged 18–70 years old) were defined as those who had suffered an isolated acute ankle sprain, which was Ottawa Ankle Rules positive, but negative for a significant ankle fracture on x-ray. Age and sex matched controls were also recruited. The controls were individuals who had not suffered a significant ankle injury, including ankle pain, function affected for more than 7 days, or the ankle caused them to report to an Emergency Department. Data is collected through a series of seven questionnaires (at baseline, 3 months, 1 year, 3 years, 5 years, 10 years, and 15 years later). The questionnaires include four sections (demographic questions; index injury, and injury history questions; functional assessment questions; and quality of life questions) and are designed to collect detailed information about the individual, their injury, potential risk factors for ankle sprains and ankle osteoarthritis, plus their medical history and any medication consumed. Discussion The Significant Ankle Ligament Injury (SALI) study aims to add to the limited knowledge regarding which factors can predict ankle sprains, complaints, and osteoarthritis. This is important because despite ankle sprains being regarded as a benign injury that resolves quickly, residual symptoms are not uncommon months and years after the injury.

What is the Effect of Lateral Ankle Ligament Injury on Syndesmotic Stability? Arthroscopic evaluation

Category: Ankle; Arthroscopy; Sports; Trauma Introduction/Purpose: Numerous studies have shown a high incidence of associated lateral ankle and syndesmotic ligamentous injuries. It is unclear, however, if there is a direct contribution of the lateral ligaments towards stabilizing the syndesmosis. Using arthroscopy, we assessed to what extent lateral ankle ligaments contribute to syndesmotic stability in the coronal and sagittal plane. Our hypothesis was that lateral ankle ligament injury has effect on syndesmosis instability. Methods: Sixteen fresh frozen above-knee amputated cadaveric specimens were divided into two groups that underwent arthroscopic evaluation for syndesmotic stability. In both the groups, the assessment was done with all syndesmotic and ankle ligaments intact and later with sequential transection of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL), the posterior talofibular ligament (PTFL), anterior inferior tibiofibular ligament (AITFL), the interosseous ligament (IOL) and the posterior inferior tibiofibular ligament (PITFL). In all scenarios, coronal and sagittal loading conditions were considered under 100N of direct force to fibula. The measurements of the distal tibiofibular coronal plane space at the anterior and posterior third of syndesmosis were performed using arthroscopic probes with increment of 0.2mm diameter. Further the sagittal translation were measured by arthroscopic scaled probe. Dunnett test was used to compare the findings of each ligamentous transection state to the intact state. A p-value < 0.05 was considered significantly defferent. Results: Compared with the intact ligamentous state, there was no difference in coronal and sagittal stability when the lateral ankle ligaments (ATFL, CFL, PTFL) and AITFL were transected (Table1 and 2, Group1). However, after subsequent transection of the IOL, or after transection of the lateral ankle ligaments (ATFL, CFL or and PTFL) alongside the AITFL and IOL, both coronal space and sagittal translation increased as compared with the intact state (p-values p<0.001 respectively) (Table1 and 2, Group2). Conclusion: Our findings suggest that lateral ankle ligaments do not directly contribute to syndesmotic stability in the coronal and sagittal plane. In concomitant acute syndesmotic and lateral ligament injury, surgeons should pay attention to whether there is combined IOL injury to determine the fixation of syndesmosis.

Quantitative Analysis of the Deltoid Ligament Degradation in Chronic Ankle Instability Patients using the CT Value

Category: Ankle; Other Introduction/Purpose: Chronic lateral ankle instability (CLAI) that is developed after multiple lateral ankle ligament injury lead to ankle osteoarthritis. Although isolated deltoid ligament injury is rare compared to lateral ankle ligament injury, deltoid ligament tear, especially deep posterior tibiotalar ligament (PTT) can be observed arthroscopically in CLAI patients. Unphysiological loading of the ankle joint with CLAI might cause degradation of the deltoid ligament. This study aimed to investigate image findings of the deltoid ligament using computed tomography (CT) value for quantitative analysis of degenerative ligament changes in CLAI patients. Methods: Among the enrolled patients who underwent ankle magnetic resonance imaging (MRI) and CT scans of the ankle, this retrospective analysis included 24 ankles without ankle osteoarthritis, osteochondral lesion of the talus (OLT), flatfoot and ankle fractures (14 males and 10 females; mean age, 42.8 years) as a control group, and 14 CLAI ankles without OLT (7 males and 7 females; mean age, 31.1 years) as CLAI group. The CT scans were performed using a 64-slice multidetector row CT. Deep PTT was detected on coronal T2-weighted MR images. Both the coronal MR and CT images were matched for analysis, then average CT values were measured using the region of interest that was applied to the detected area of deep PTT on the CT images. Spearman’s correlation coefficient was used to evaluate the correlation between age and CT value in the control group. Results: The strong negative correlation was identified between age and CT value in the control group (Spearman ρ= -0.88; p < 0.001). The CT value of the deep PTT are degraded with aging. Mean CT value of deep PTT in participants under 60 years old were 79.9 HU (95% CI, 75.1-84.8) in the control group (18 ankles), and 66.5 HU (95% CI, 58.6-74.5) in the CLAI group (14 ankles) (Welch’s t test; p = 0.005). Conclusion: MRI techniques and protocols recently have been developed, however, some limitations remain such as a quantitative evaluation of the ligament. Our findings suggest that the CLAI can lead to degradation of the deltoid ligament via an overloading of medial ankle structures. Additionally, CT values should be useful for quantitatively evaluating ligament status including degenerative changes.

Magnetic Resonance Image Analysis of Ankle Joint Motion Injury in Athletes

Objective: Magnetic Resonance Imaging (MRI), which is used to analyze common sports injuries in the ankle joint, provides guidance for clinical treatment. Methods: MRI of the ankle joint was performed in 53 athletes with ankle joint injury. The MRI features of the ankle ligament injury, the combined ligament injury characteristics and the ligament injury characteristics of the ankle were evaluated. Results: 53 athletes with a total of 74 ligament injuries, partial tear or complete rupture of the ligament, high-signal effusion shadow, soft tissue edema and adjacent bone marrow edema around the boundary, chronic injury is mainly characterized by irregular thickening or thinning of the ligament and uneven signal. There were 32 cases of lateral collateral ligament injury, the main ligament injury was 42. Conclusions: MRI is used to examine athletes with acute and chronic ligament injury, and the clinical impact characteristics are quite different. Therefore, MRI analysis can be used as the main diagnostic basis for athletes with acute and chronic ankle ligament injury. It provides reference and reference value for the determination of clinical treatment plan.

Effect of Early Physiotherapy after Lateral Ankle Ligament Injury on Pain and Function. Systematic Review

Background. Lateral ankle ligament injuries are most common in sports, which affects athletes in all ages. It has been found that lateral ankle ligaments are injured in 1 of 10000 physically active people. Higher sports level professional players and amateurs need to return to sport early with no physical, psychological and economic consequences. Studies search for the most effective treatment after lateral ankle ligament injuries. Research aim – to perform a systematic review and determine the effect of early physiotherapy on pain and function after lateral ankle ligament injury. Methods. We conducted literature search using the Pubmed, Ebsco, Pedro, Google scholar databases, and chose controlled trials where early physiotherapy orientated to pain and function was used. Results. In control groups where traditional immobilization with RICE method was used, pain decreased to 1.96 ± 1.33 points, in the intervention groups who had early physiotherapy and RICE method, pain decreased to 1.53 ± 1.23 points.
