NCT ID: NCT03012529 Recruiting - Diabetes Clinical Trials

Investigation of Rifampin to Reduce Pedal Amputations for Osteomyelitis in Diabetics

VA INTREPID
Start date: January 22, 2018
Phase: Phase 4
Study type: Interventional

The purpose of this research study is to determine if rifampin, an antibiotic (a medicine that treats infections), is effective in treating osteomyelitis (infection of the bone) of the foot in diabetic patients. Despite use of powerful antibiotics prescribed over a long period of time, many diabetic patients remain at a high risk for needing an amputation of part of the foot or lower leg because the osteomyelitis is not cured. Some small research studies have shown that addition of rifampin to other antibiotics is effective in treating osteomyelitis in both diabetics and non-diabetics. However, because few diabetics with osteomyelitis have been studied, there is no definite proof that it is better than the usual treatments for diabetic patients. If this study finds that adding rifampin to the usual antibiotics prescribed for osteomyelitis reduces the risk for amputations, doctors will be able to more effectively treat many Veteran patients with this serious infection. Improving treatment outcomes is an important healthcare goal of the VA.

NCT ID: NCT02476838 Recruiting - Amputation Clinical Trials

Hand Transplantation

Start date: June 2, 2015
Phase: N/A
Study type: Interventional

The purpose of this study is to see if an investigational surgery that transfers tissue from a non-living donor to living individual will help restore greater function, appearance, and sensation to the hand and forearm areas of individuals who have suffered traumatic injury to the hand and forearm. This procedure is called a hand allotransplantation or "hand transplant". This study will also collect data on how patients do during and after having a hand transplant from a nonliving donor. Recovery and outcomes will be observed through clinical exams, x-rays, blood and tissue tests, and other associated evaluations at all follow up visits.

NCT ID: NCT02395497 Recruiting - Amputation Clinical Trials

Human Penile Allotransplantation

Start date: June 2014
Phase: Phase 2/Phase 3
Study type: Interventional

Injuries to the genitalia are of concern to the military with emphasis placed on the surgical reconstruction and psychological health of these Wounded Warriors. However, despite significant surgical advances in microvascular surgery and autologous free tissue transfer, conventional reconstructions cannot truly replace the complicated structures and functions of the penis including the urethra, erogenous sensation, and erectile corporal bodies. Conventional reconstruction poses several challenges: patients may not have sufficient donor tissue due to other injuries or previous surgery; multiple operations are often needed to restore the neophallus; the final reconstruction only approximates the penis' native form; recreating the urethra is challenging and the new urethra is prone to stricture and fistula formation; the erectile function necessary for sexual intercourse is often lacking; and insufficient protective sensation can lead to penile implant extrusion, infection, subsequent explantation or loss of the reconstruction. The investigators propose this clinical trial to determine functional outcomes and quality of life for Wounded Warriors and civilians who choose to undergo penile allotransplantation. The investigators will combine extensive experience performing total penile reconstruction in a large population affected by congenital, traumatic, and therapeutically extirpated Genitourinary deformities and expertise in reconstructive transplantation using an immunomodulatory protocol to for this study. The investigators anticipate penile transplantation can potentially replace "like with like," restoring the appearance, anatomy, and function of the recipient in a manner far superior to autologous reconstruction. This project will establish the ability to perform penile allotransplantation using an immunomodulatory protocol and will compare outcomes with conventional phalloplasty patient results. Study Design: This is a non-randomized subject self-controlled clinical trial to implement a cell-based immunomodulatory protocol for penile allotransplantation. An intermediate deliverable is achieving allograft survival and functional return with reduced dosing/frequency of maintenance immunosuppression on steroid-free monotherapy (tacrolimus) immunosuppression. The long-term deliverable and goal is to demonstrate superior outcomes when compared to satisfaction and QOL in conventional phalloplasty patients 12-60 months post-transplant.

Evaluation of a Pro-Active Dynamic Accommodating Socket

PADS
Start date: January 2012
Phase: N/A
Study type: Observational

The primary objective of this study is to assess the effectiveness of the pro-active dynamic socket (PADS) on increasing socket comfort and fit for transfemoral and transtibial amputees during ambulation and rest, addressing residual limb volume fluctuations with a controlled flow bladder system.

1. To explore the pathology of nerve, vascular, and skin in the amputated leg 2. To diagnose small-fiber sensory neuropathy of the contralateral leg by investigating the skin intervention 3. To search for (1) mechanisms of amputation and (2) prevention measures for further amputation in the currently healthy-looking limb

NCT ID: NCT00771589 Recruiting - Amputation Clinical Trials

Active Knee Prosthesis Study for Improvement of Locomotion for Above Knee Amputees

Start date: May 2008
Phase: N/A
Study type: Interventional

The purpose of this study is to develop a robust, low-power, stable, and light weight, active knee prosthetic device that can dramatically increase gait symmetry and walking economy of a transfemoral amputee during walking. State of the art prosthetic knees can be classified into three main classes: a) mechanically passive, b) variable-damping, and c) powered. Although the devices within each of these classes offer some advantages for above-knee amputees, their overall performance still presents some deficiencies. Artificial knees in the first two groups are predominantly damping devices, incapable of providing positive power output. Moreover, current powered prostheses are heavy and inefficient in their energy consumption, and/or they have a limited range of motion. To overcome such inadequacies, we have designed a novel prosthetic knee device with a biomimetic approach. The design of the active knee prosthesis is inspired by the antagonistic muscle anatomy of the human knee joint. This device mimics the synergistic muscle activity at the knee using a double series-elastic actuator (SEA) system that resembles the major mono-articular muscle groups that help flex and extend the knee joint. The agonist-antagonist SEA knee architecture will allow for precise force control of the knee joint, mimicking the spring-like behavior of the human knee, as well as providing adequate energy for forward progression of the body. The SEA has been previously developed and tested on legged robots. Also, the SEA has been successfully applied to the development of an actuated ankle-foot orthoses (AAFO) at MIT AI Lab. The mechanical architecture of the active knee prosthesis allows for independent engagement of flexion and extension tendon-like, series springs for the control of joint position and impedance, as well as net joint torque. Furthermore, this architecture permits a joint rotation with near zero friction, allowing the controller to take advantage of the passive dynamics of the system, thus, augmenting the overall energetic efficiency of the system.

Acupuncture for the Treatment of Phantom Limb and Residual Limb Pain After Amputation

Start date: September 2006
Phase: Phase 1
Study type: Interventional

The purpose of this study is to identify the best treatment sequence and combination of acupuncture points for the treatment of phantom limb or residual limb pain in the traumatic/surgical amputee.

NCT ID: NCT00301444 Recruiting - Pain Clinical Trials

A Study to Test the Effectiveness of Mirror-Box and Mental Visualization Treatments on Phantom Limb Pain

Start date: March 2006
Phase: N/A
Study type: Interventional

The researchers propose to conduct a pilot study on the efficacy of mirror-box and mental visualization treatments on phantom limb pain. The trial will last for 4 months and during the first month, data will be gathered daily on the number of episodes of phantom limb pain, the average length of episodes, average intensity of pain, and worst intensity of pain. In addition, the rapidity of pain relief, the length of therapy needed to sustain long-lasting pain relief, and whether use of these two treatment methods during rehabilitation can provide sustained and/or permanent pain relief will be determined. Cognitive testing will also be performed to determine the effect of limb amputation on cognition and mood with results being compared to an on-going study of similar effects in patients with chronic (> 3 months) limb amputation. The inclusion of subjects with phantom limb pain in upper extremity amputations has recently been approved.
