5 Clinical Trials for Various Conditions
The purpose of this study is to compare the clinical and radiographic outcomes of a randomized, consecutive series of adult patients, with an acquired flatfoot, treated with a lateral column lengthening using an allograft bone wedge versus a titanium porous metal implant (Biofoam, Wright Medical). Null hypothesis: At six months postoperatively, there is no difference in the degree of correction as measured by the talonavicular coverage angle between patients randomized to allograft and Biofoam. Alternative hypothesis: At six months postoperatively, the degree of correction as measured by the talonavicular coverage angle will be less in patients randomized to allograft than the degree of correction in patients randomized to Biofoam.
The use of bio-integrative implants in orthopedic surgery is growing exponentially. As many biomechanical and histological studies were able to sustain its structural and biological properties, few clinical studies are available to support its advantages, such as good osteosynthesis, lower rates of removal, and diminished implant-related artifact in imaging studies. This information is vital to providers when choosing the proper material and planning postoperative treatment. This trial intends to test the capacity of the bioabsorbable screws in reaching the same clinical and radiographical outcomes of the current metallic screws.
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.
Range of motion at ankle joint and subtalar joint will be assessed before and after utilization of ARM device. The changes in range of motion will be recorded and compared to literature.
