Compared to conventional physiotherapy, does the use of an ankle trainer device after Weber B ankle fracture operation improve outcome and shorten hospital stay? A randomized controlled trial.

ABSTRACT: OBJECTIVE:To compare the functional outcomes and length of hospital stay for patients treated with conventional physiotherapy compared to a new ankle trainer device after Weber B ankle fractures. DESIGN:The patients were randomized, and then followed up at 3, 6, 12 and 52?weeks by a blinded physiotherapist. SETTING:This study was done at a level 1 trauma centre. SUBJECTS:One hundred and forty consecutive patients with Weber B ankle fractures that were operated on were screened for eligibility, of whom 113 were included in the study. INTERVENTIONS:Conventional physiotherapy with stretching exercises, using a non-elastic band or using new ankle trainer. MAIN MEASURES:Outcomes were evaluated with Olerud-Molander ankle score, Visual analogue scale for pain and ankle dorsiflexion at 3, 6, 12 and 52?weeks follow-up. Time of hospitalization and complications were registered. RESULTS:Superior Olerud-Molander ankle scores were observed at three?weeks follow-up in the ankle trainer group 40.9 (10.8), compared to the conventional group 35.3 (14.2) (P?=?0.021). At one-year follow-up, there was no difference between the groups (P?=?0.386). The ankle trainer group had a shorter hospital stay with a mean 2.6?days (0.98) compared to 3.2?days (1.47) in the conventional group (P?=?0.026). CONCLUSION:The patients who were treated with the new ankle trainer device recovered more rapidly, evaluated by the Olerud-Molander ankle score and had a shorter stay in hospital compared to the conventional physiotherapy group. No between group differences could be observed at long-term follow-up.

Project description:BackgroundConventionally, transsyndesmotic fibula fractures with concomitant signs of deltoid ligament injury have been considered unstable and thus treated operatively. Recent studies have indicated that partial deltoid ligament rupture is common and may allow for nonoperative treatment of stress-unstable ankles if normal tibiotalar alignment is obtained in the weightbearing position. Biomechanical support for this principle is scarce. The purpose of this study was to evaluate the biomechanical effects of gradually increasing deltoid ligament injury in transsyndesmotic fibula fractures.MethodsFifteen cadaveric ankle specimens were tested using an industrial robot. All specimens were tested in 4 states: native, SER2, SER4a, and SER4b models. Ankle stability was measured in lateral translation, valgus, and internal and external rotation stress in 3 talocrural joint positions: 20 degrees plantarflexion, neutral, and 10 degrees dorsiflexion. Talar shift and talar valgus tilt in the talocrural joint was measured using fluoroscopy.ResultsIn most tests, SER2 and SER4a models resulted in a small instability increase compared to native joints and thus were deemed stable according to our predefined margins. However, SER4a models were unstable when tested in the plantarflexed position and for external rotation in all positions. In contrast, SER4b models had large-magnitude instability in all directions and all tested positions and were thus deemed unstable.ConclusionThis study demonstrated substantial increases in instability between the SER4a and SER4b states. This controlled cadaveric simulation suggests a significant ankle-stabilizing role of the deep posterior deltoid after oblique transsyndesmotic fibular fracture and transection of the superficial and anterior deep deltoid ligaments.Clinical relevanceThe study provides new insights into how the heterogenicity of deltoid ligament injuries can affect the natural stability of the ankle after Weber B fractures. These findings may be useful in developing more targeted and better treatment strategies.

Project description:BackgroundAnkle fractures are one of the most common orthopedic injuries, and although most patients have a satisfactory outcome following operative fixation, there are patients that have persistent pain despite anatomic reduction. Intra-articular injuries have been suggested as one potential cause of these suboptimal outcomes. Our study assesses the clinical impact of performing an ankle arthroscopy during ankle fracture open reduction and internal fixation (ORIF).MethodsThis was a retrospective chart review of all patients who underwent operative fixation of a bimalleolar or trimalleolar ankle fracture at our institution from 2014 through 2018. We extracted all demographic data, fracture pattern, operative procedures performed, tourniquet times, arthroscopic findings and any arthroscopic interventions. We then conducted a phone and e-mail survey. Our study included 213 total patients (142 traditional ORIF, 71 ORIF plus arthroscopy) with an average age of 40 years. The average follow-up was 32.4 months with a survey follow-up rate of 50.7% (110/213).ResultsThe average tourniquet time for the arthroscopy cohort was 10 minutes longer (89 minutes vs 79 minutes). During the arthroscopy, there was a 28% (20/71) rate of full-thickness osteochondral lesions, 33% (24/71) rate of loose bodies, and a 49% (35/71) rate of partial-thickness cartilage injury. The mean Patient Reported Outcome Information System (PROMIS) physical function score among Weber B fibula fractures was 45.8 and 42.3 in the arthroscopy and nonarthroscopy groups, respectively (P = .012). In addition, the patient satisfaction rate in Weber B fibula fractures was higher in those patients who underwent arthroscopy compared with ORIF alone (93% vs 75%, P = .05). Patients who had a tibiotalar joint dislocation at the time of the ankle fracture had a significantly higher PROMIS physical function score (46.6 vs 40.2, P = .005) when their surgery included arthroscopy.ConclusionAnkle arthroscopy at the time of ORIF led to statistically significant improvements in patient-reported outcomes for Weber B fibula fractures and ankle dislocations. There was no increase in complication rates and the arthroscopy took 10 minutes longer on average.Level of evidenceLevel III, retrospective cohort study.

Project description:IntroductionIntra-articular fractures are the leading etiology for posttraumatic osteoarthritis (PTOA) in the ankle. Elevation of proinflammatory cytokines following intra-articular fracture may lead to synovial catabolism and cartilage degradation. We aimed to compare cytokine levels in injured and healthy ankle joints, examine the longer-term cytokine levels in fractured ankles, and investigate the association between cytokine levels in fractured ankles and plasma.Materials and methodsIn this cross-sectional study, synovial fluid (SF) and plasma of forty-seven patients with acute intra-articular ankle fractures and eight patients undergoing implant removal were collected prior to surgery. We determined concentrations of sixteen inflammatory cytokines, two cartilage degradation proteins, and four metabolic proteins and compared the levels in acutely injured ankles with those of the healthy contralateral side or during metal removal. Cytokine levels in injured ankles were also compared to serum cytokine levels. Nonparametric Wilcoxon rank-sum and Spearman tests were used for statistical analysis, and a p value below 0.05 was considered significant.ResultsCompared to the healthy ankles, the synovial fluid in ankles with acute intra-articular fracture had elevated levels of several proinflammatory cytokines and proteases (IL-1β, IL-2, IL-6, IL-8, IL-12p70, TNF, IFNγ, MMP-1, MMP-3, and MMP-9) and anti-inflammatory cytokines (IL-1RA, IL-4, IL-10, and IL-13). The levels of cartilage degradation products (ACG, CTX-2) and metabolic mediators (TGF-β1 and TGF-β2) were also significantly higher. Synovial concentrations of ACG, IL-12-p70, IFNγ, IL-4, and bFGF correlated with serum levels. While most of the examined synovial cytokines were unchanged after implant removal, IL-4 and IL-6 levels were upregulated.ConclusionsWe show that an acute ankle fracture is followed by an inflammatory reaction and cartilage degeneration. These data contribute to the current understanding of the protein regulation behind the development of PTOA and is a further step towards supplementing the current surgical treatment. This cross-sectional study was "retrospectively registered" on the 31th October 2017 at ClinicalTrials.gov (NCT03769909). The registration was carried out after inclusion of the first patient and prior to finalization of patient recruitment and statistical analyses: https://clinicaltrials.gov/ct2/show/NCT03769909?term=NCT03769909&draw=2&rank=1.

Project description:Objective"Visual Restitution Therapies" (VRT) claim to ameliorate visual field defects of neurological patients by repeated visual light stimulation, leading to training-related neuroplasticity and resulting in reconnection of lesioned neurons in early cortical areas. Because existing systems are stationary, uncomfortable, and unreliable, we developed a training instrument based on virtual reality goggles. The goal of the "Salzburg Visual Field Trainer" (SVFT) is twofold: (1) The device facilitates the clinical evaluation of established neuropsychological rehabilitation approaches, such as VRT. (2) The device enables patients to independently perform VRT based (or other) neuropsychological training methodologies flexibly and comfortably.Methods and analysisThe SVFT was developed on the principles of VRT. Individual configuration of the SVFT is based on perimetric data of the respective patient's visual field. To validate the utmost important aspect of neuropsychological rehabilitation methodologies-that is displaying stimuli precisely in desired locations in the user's visual field-two steps were conducted in this proof-of-concept study: First, we assessed the individual "blind spots" location and extent of 40 healthy, normal sighted participants. This was done with the help of our recently developed perimetric methodology "Eye Tracking Based Visual Field Analysis" (EFA). Second, depending on the individual characteristics of every participant's blind spots, we displayed-by means of the SVFT-15 stimuli in the respective locations of every participants' blind spots and 85 stimuli in the surrounding, intact visual area. The ratio between visible and non-visible stimuli, which is reflected in the behavioral responses (clicks on a remote control) of the 40 participants, provides insight into the accuracy of the SVFT to display training stimuli in areas desired by the investigator. As the blind spot is a naturally occurring, absolute scotoma, we utilized this blind area as an objective criterion and a "simulated" visual field defect to evaluate the theoretical applicability of the SVFT.ResultsOutcomes indicate that the SVFT is highly accurate in displaying training stimuli in the desired areas of the user's visual field with an accuracy of 99.0%. Data analysis further showed a sensitivity of .98, specificity of .99, a positive predictive value of .96, a negative predictive value of .996, a hit rate of .99, a random hit rate of .74 and a RATZ-Index of .98. This translates to 14.7% correct non-reactions, 0.7% false non-reactions, 0.3% false reactions and 84.3% correct reactions to displayed test stimuli during the evaluation study. Reports from participants further indicate that the SVFT is comfortable to wear and intuitive to use.ConclusionsThe SVFT can help to investigate the true effects of VRT based methodologies (or other neuropsychological approaches) and the underlying mechanisms of training-related neuroplasticity in the visual cortex in neurological patients suffering from visual field defects.
