Filter by:The post-operative treatment of pediatric patients operated for the correction of flat foot, sees today the use of preformed leg-foot splint (Walker) as an alternative to the application of plaster casts. The change of the immobilization system has led to the appearance of problems of tolerability in particular in the skin. The aim of the study is to assess whether by placing a polyurethane foam dress at the heel in the immediate postoperative period until removal of the Walker, the rate of skin lesion and pain is reduced.
The purpose of this study is to explore the long-term effects that orthotics imposes on the structure and function of the foot. The objectives of the study are to determine if the use of custom-made foot orthotics (CFO) cause: (a) changes to the structure of the plantar intrinsic muscles, (b) changes in the rate of muscle activity and timing in the plantar intrinsic muscles and (c) creates any changes in balance control during gait termination. The aim of the study is to enhance the appropriate dispensing of orthotics, and whether additional measures, such as rehabilitation exercises are necessary to increase their overall effectiveness in the clinical setting.
The purpose of this study is to compare computer aided design/computer aided manufacturing (CAD/CAM) and semi-custom insole types on pain, quality of life and physical performance and also to decide whether they are necessary in treatment of painful flexible flatfoot.
The purpose of this study is to investigate the efficay of functional plantar orthoses on flatfoot in children.
This study will investigate the effect of foot orthoses on two common conditions (ankle osteoarthritis and symptomatic adult onset flat feet) by using a custom biplane X-ray system the group has developed to very accurately and precisely quantify foot bone motion. The investigators will vary the design of the orthoses and subjects will be examined to find out which are most effective at improving function.
The Evans calcaneal lengthening is a common surgical correction used for children with spastic cerebral palsy (CP) and painful flat feet. This procedure involves the insertion of a trapezoidal bone graft into the calcaneus bone. Both autograft and allografting materials have been used for this procedure, but both types of grafting materials have associated limitations. Autologous grafting materials, which are harvested from the iliac crest at the time of surgery, are associated with high rates of prolonged donor site pain. There is limited bone available from the iliac crest. For this reason autologous bone grafts are not commonly used for the Evan's procedure. Cadaver allografting materials are variable in their mechanical and geometric properties. Recently, xenografting materials have been developed that have consistent mechanical properties and are available in a larger size that is formed to fit the individual patient intraoperatively. The purpose of this study is to evaluate the long term outcomes of the procedure with the different graft options. Another purpose is to compare the difference in surgical correction obtained with the cadaver allograft and the xenografting materials. This study will also observe and evaluate a wide range of outcome variables that encompass multiple levels of patient care, from clinical observation to parent and patient satisfaction, and compare these with the observed changes in the radiographic and plantar pressure parameters of the foot. This data will be evaluated pre to post surgery and for two years of follow-up time. The aim is to uncover the characteristics of collapse observed with the two different grafting materials.
There is no consensus on the surgical treatment of unremitting, painful flatfeet in children. Subtalar arthroereisis has gained notoriety although there is a paucity of literature on its biomechanical effects. The goal of the investigators was to compare a group treated with subtalar arthroereisis with another group undergoing lateral column calcaneal lengthening. The investigators hypothesis was that the results of arthroereisis would be equivalent to the more established method of calcaneal lengthening.
The purpose of this study is to compare the average joint motion and joint axis orientation of the hindfoot bones between patients diagnosed with adult-acquired flatfoot disorder (AAFD) and a control group of patients without foot deformity, using weight-bearing CT technology.
People with anatomical leg length discrepancy (LLD) commonly presented excessive subtalar pronation of the long leg compared to their short leg in order to equalize leg length. Although such compensation may decrease the stress in the pelvis and/or low back region, the pronated foot may lead to excessive stress loading onto the ankle or foot, resulting in musculoskeletal injuries. Clinically, the pronated foot has been effectively controlled using functional orthoses with proper posting by adjusting the subtalar joint in the neutral position. But for people with compensatory pronated foot resulted from anatomical LLD, to control excessive pronation of the long leg would exaggerate their asymmetry in leg length. Instead, the pronated foot can be controlled simply by adjusting the length of the short leg. However, there is limited evidence of such intervention in previous literature. The purpose of this research project is going to determine the effect of leg length adjustment on pronation control in people with anatomical LLD. According to this purpose, 5 study objectives will be developed: 1) to examine the validity and reliability of LLD measurement using a hand-held laser distance meter, 2) to compare the foot types before and after leg length adjustment, 3) to compare the kinetic variables before and after leg length adjustment during quiet stance, 4) to compare the kinetic variables before and after leg length adjustment during level walking, and 5) to compare symptoms and functional levels related to low back pain (LBP) before and after leg length adjustment. The present research project will be designed as a convenience sampling, prospective, quasi-experimental, and pretest/posttest design. There will be 2 parts in this research: 1) validity and reliability test of laser measure for leg length and 2) foot morphology and kinetic analysis before and after leg length adjustment. For the first part of this research, 10 male adults and 20 adults will be recruited for the validity and reliability tests respectively. Anthropometric measurements, including body height, body weight, foot length, foot width, and heel-ball distance, will be measured after a consent form is signed. Participants of the validity test will receive standing pelvic radiography and laser measure to measure their leg length. Each participant of the reliability test will receive 2 sessions of laser measure using a hand-held laser-distance meter. For the first session, all laser measurements will be employed twice by 2 raters with a rest interval of more than 5 min. One week later, another session of laser measure will be given again by one of these 2 raters. Intraclass correlation coefficient (ICC) will be used to test the interrater reliability, intrarater reliability, and validity of the laser measure method. Standard error of measurement (SEM), and small real difference (SRD) will be calculated to represented intrarater reliability also. For the second part of the research, another thirty adults with compensatory pronated foot resulted from LLD will be included in the research project but the sample size will be adjusted to the appropriate number according to power analysis. Each participant will be asked to fill out the visual analog scale (VAS) and the Oswestry Disability Index (ODI) and receive tests containing foot type examination, quiet stance with eye opening, quiet stance with eye closed, and level walking. All tests will be performed before and after leg length adjustment. The experiment will be completed after collecting 3 successful trials for each test. All procedures will be done one month later. ANOVA with repeated measures will be calculated to compare the differences in these variables among before, immediately after, and 1 month following leg length adjustment when the data fit the assumptions of normal distribution. Discrete variables or variables with non-normal distribution were tested using the Friedman test. All statistical analyses will be calculated using SAS 9.1.3. The significant level was set at α = 0.05 while the power was at 0.8. Five possible results may be expected from conducting this research project: 1) there will be good validity and reliability of the laser distance meter to measure LLD, 2) there will be significant differences in measurements of foot type before and after leg length adjustment, 3) there will be significant differences in kinetic data during quiet stance before and after leg length adjustment, 4) there will be significant differences in kinetic data during level walking before and after leg length adjustment, and 5) symptom and functional level related to LBP will improve after leg length adjustment. Completion of this research project will be projected to provide solid and objective evidences for leg length adjustment through views of morphology and kinetics in people with pronated foot due to anatomical LLD.
In this study we are trying to determine the incidence of flat foot (also called pes planus) among patients who have had an ankle fracture. As compared to the general population, it is predicted that the incidence of pes planus will be higher among people who have fractured their ankle.
