Filter by: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.
Using double blind, randomized controlled design to study the short-term therapeutic effects of customized arch-support shoe insoles to children with flat foot.
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.
Pes planovalgus, also called flat foot, is a common foot deformity characterized by a flattening of the foot's longitudinal arch and is accompanied by a dysfunction of the posterior tibial tendon ("posterior tibial tendon dysfunction" or "PTTD"). Early stages of this pathology are thought to be treated with non-surgical therapy options like foot orthoses (relief of tendon stress by mechanical unloading of the arch), strengthening exercises or basic physiotherapeutic measures. Recent literature clearly states the urgent need for high quality studies to evaluate the proposed non-surgical treatments (Bowring 2009, 2010). There is only one high quality study available that shows benefits of orthoses therapy and exercise (Kulig 2009). No study to date evaluated functional changes pre-post in dynamic movement pattern like gait or stair climbing. The widespread use of several non-surgical treatment strategies lead to extensive financial expenses of the health care system. An optimized therapeutic strategy could eventually lead to more efficient health care investments. The presented proposal addresses this latest knowledge and aims to analyse non-surgical treatment strategies to Cure Pes Planovalgus associated Complaints (CurePPaC) in the CurePPaC Study.
The purpose of this study is to determine whether structural calcium ceramic bone graft substitute (ReproBone™) is non-inferior compared to autologous tricortical iliac crest bone graft in lateral calcaneal lengthening osteotomies in pediatric patients and reduces postoperative pain. To groups of patients (age 5-16) will be compared. One group randomized to autologous bone graft and the other group randomized to calcium ceramic. The evaluation will be based on radiostereometric analysis, pedobarography, Patient reported outcome assessment (Oxford Ankle Foot Questionnaire), and pain (measured by visual analog scale and numerical range scale).
In this foot deformity (plano valgus) surgery may be indicated. The deformity is corrected with an osteotomy at the heelbone. In most cases bone graft material has to be obtained from the iliac crest to support the osteotomy. In the planned study a group of children will be operated with an artificial bone graft material and thus avoiding the need harvesting of bone graft at the iliac crest.
In a group of children with severe and painful flatfeet lengthening procedures of calcaneus can be indicated. In this study the investigators use an artificial bone graft technique to avoid removing bone graft from the iliac crest.
