11 Clinical Trials for Various Conditions
This is a Humanitarian Device Exemption (HDE) approved device. The purpose of this study is to evaluate the continued safety and probable benefit of the restor3d Total Talus Replacement device in commercial use.
Humanitarian Device Exemption Approved Patient Specific Talus Spacer Post Approval Study.
This study is a retrospective analysis of patients who underwent surgery using a total talus replacement (TTR) implant with or without concurrent total ankle replacement and/or subtalar fusion. This study seeks to analyze the clinical and radiographic outcomes of TTR implant recipients and generate additional data on the safety and benefit of the TTR implant.
This study is testing the effectiveness of augmentative and alternative communication technology among deaf or hard of hearing children for improving language development. Children will be randomized to receive either the technology intervention or treatment as usual
Avascular necrosis of the talus is a difficult problem to manage, especially in the young and healthy. The only option, historically, has been a talectomy and hindfoot fusion. While this is a viable option, it is not without its morbidity. Arthritis of surrounding joints is common, occurring anywhere from 1-10 years after the procedure. This is especially true in younger patients, where loss of motion can be life altering both physically and mentally. The search for alternatives has been limited. Recently, 3D printing has become more ubiquitous and affordable and newer medical alternatives have arisen thanks to this technology. The 3D custom talus is relatively new in the orthopaedic community, but has been used at several centers with good success. It has been shown to re-establish the normal alignment of the foot, preserve motion (with some achieving almost physiologic motion), and allow for almost normal ambulation. However, the data is still limited and further study is necessary. Our facility was recently approved to perform this procedure. Our hypothesis is that custom 3D printed talar body replacements, either used alone or with total ankle replacements, will maintain physiologic motion, have no difference in complications when compared to hindfoot fusions with allograft, lead to good outcome scores and patient satisfaction scores. Patients diagnosed with avascular necrosis of the talus who have already decided to undergo a procedure involving a 3D custom talus as part of their standard care (talar replacement, total ankle/total talus, etc) will be enrolled in the study. Patients will follow standard post-operative protocols and return to clinic at designated time periods (2 weeks, 6 weeks, 3 months, 6 months, 1 year). X-ray evaluation, Range of motion, return to ambulation, walking speed and patient reported outcomes will be evaluated at each visit. Data will then be compared with baseline measurements and use to determine the progression of patients over time after the procedure
Osteochondral lesions of the talus are thought to be due in large part to traumatic events or repetitive microtrauma that causes damage to both the articular cartilage and the subchondral bone. There are several treatment modalities for osteochondral lesions of the talus but there is no consensus as to which is the superior method for repair. Treatment modalities are aimed at regenerating articular cartilage. Microfracture is a widely accepted and utilized treatment for osteochondral lesions. This procedure results in pluripotent bone marrow stem cells filling the defect and ultimately differentiating into fibrocartilage-producing cells \[1\]. This technique has shown good results in both short- and medium-term follow-up for smaller lesions. Bone marrow aspirate contains mesenchymal stem cells and growth factors with cartilage regeneration potential. Bone marrow aspirate concentrate (BMAC) is a treatment modality that has shown to have to potential to produce hyaline cartilage. This study aims to analyze the effect of adding BMAC to the standard microfracture procedure in terms of clinical and radiographic outcomes in comparison to patients who only underwent microfracture treatment.
This is a a study to identify inherited disease genes. The study will use molecular techniques to map genetic diseases using techniques such as Affymetrix SNP chips. The powerful combination of the information generated by the Human Genome Project and technical advances such as microarrays enables attempts to identify genes responsible for inherited disorders more possible than ever before. Starting with even modest pedigrees of only a few individuals, or even single individuals, it is possible to identify the gene(s) involved. It is proposed to collect up to 20 ml of peripheral blood and/or buccal cell samples from subjects and relevant family members. Currently the following disorders are approved for investigation. The current list of disorders: Aarskog-Scott syndrome, Café-au-Lait spots, Cerebral cavernous malformation, delXp, del2q, del10p, del11q, del12p, del13q, del14q, del16q, del17q, del18q, del Xp21, Choreoathetosis, Congenital Vertical Talus (CVT), Clubfoot, Tarsal coalition and other congenital limb deformities, Cystic Fibrosis (CF)-like disease, Desbuquois syndrome, Droopy Eyelid syndrome (Ptosis), Fanconi-Bickel syndrome (FBS), FENIB (familial encephalopathy with neuroserpin inclusion bodies), FG syndrome, Idiopathic generalised epilepsy (IGE), Renpenning syndrome, transient neonatal diabetes with 6q UPD, translocation (13;14), translocation (3;8), translocation (2;18), Uncharacterized familial dementia and X-linked mental retardation (XLMR).
The purpose of this study is to determine the clinical efficacy of the application of bone marrow aspirate concentrate (BMAC) as a supplement to microfracture in the treatment of osteochondral lesions of the talus (OLTs).
Enhancing Wound Perfusion in High-Risk Lower Extremity Orthopaedic Surgery: A Feasibility Study on Nitropaste Using Intraoperative SPY Imaging.
The aim of this randomized controlled trial is to assess if manual therapy improves mobility, gait, and balance more than a control group for patients who have undergone open reduction internal fixation (ORIF) after an ankle/hindfoot fracture.
The purpose of this post-market clinical study is to collect long-term outcomes for DeNovo NT Graft treatment of articular cartilage lesions in the ankle in a standard clinical setting. Outcomes to be assessed include pain, function, activity levels and healthcare resource use.
