5 Clinical Trials for Various Conditions
Postoperative pain remains undertreated with inadequate analgesic options. Opioids have well-known limitations for both individuals and society; single-injection and continuous peripheral nerve blocks provide intense analgesia but are limited in duration to 24-72 hours; and current neuromodulation options-with a duration measured in weeks and not hours-are prohibitively expensive and require an additional procedure. One possible solution is a device currently under investigation to treat postoperative pain. The RELAY system (Gate Science, Moultonborough, New Hampshire) is comprised of a basic catheter-over-needle device to allow administration of a single-injection of local anesthetic via the needle (or catheter) followed by a perineural local anesthetic infusion via the remaining catheter (when desired). Subsequent to the local anesthetic administration, instead of removing the catheter as with all previous continuous peripheral nerve block equipment, electric current may be delivered via the same catheter and an integrated pulse generator for up to 28 days. This is potentially revolutionary because it would allow an anesthesiologist to deliver (1) a single-injection peripheral nerve block; (2) a continuous peripheral nerve block; and (3) neuromodulation using a single device that can theoretically be placed in the same amount of time required for a single-injection peripheral nerve block. Instead of providing fewer than 24 hours of postoperative analgesia, up to 28 days of pain control could be delivered without disruption of existing practice patterns. The ultimate objective of the proposed investigation is to prepare for a randomized clinical trial investigating the use of the RELAY device to provide postoperative analgesia. This feasibility study will be a series of participants all receiving both local anesthetic and electric current via a single device (RELAY, Gate Science, Moultonborough, New Hampshire). The purpose will be to optimize the insertion approach and stimulation administration during the first 7 days following foot and shoulder surgery as well as training the clinical investigators.
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.
Ankle arthritis is associated with debilitating pain and chronic disability. For the treatment of severe ankle arthritis, total ankle arthroplasty (TAA) is one treatment option. Postoperative pain management in joint arthroplasty is an ongoing and relevant issue. The purpose of this study is to examine if differences exist in postoperative pain control, overall patient satisfaction, and use of narcotics using an intra-articular injection in the operating room compared with a peripheral nerve block in patients undergoing TAA.
The purpose of this study is to determine whether custom-made foot orthoses generate a significant decrease in the perception of pain among individuals with foot pain and/or ankle pain.
This project proposes to examine the difference in effectiveness of fracture boots and carbon fiber braces in the management of gait abnormalities and pain relief due to ankle pain from arthritis due to ankle bleeds. Fracture boots are "walking casts" that you can put on and take off. They prevent the ankle from moving and have a curved sole to mimic normal walking. They can help relieve pain of ankle arthritis from ankle bleeds by stopping ankle motion and absorbing some of the body's own weight while walking. Carbon fiber braces use newer technology resulting in lighter and smaller braces. They are designed to assist with helping clear the toe and straighten the knee while walking. Gait analysis wearing both the fracture boot and carbon fiber brace will be performed by walking on a mat equipped with pressure sensors and will examine the effect of the fracture boot and the carbon fiber brace on how you walk. These tests will be compared to walking on the mat without either brace. The sensors on the mat will measure different aspects of gait such as step length and foot position. You will be asked questions about how much ankle pain you have using no brace compared to each brace. People with hemophilia A or B and ankle pain from bleeds will be asked to participate. They will be approached during routine clinic visits and will also be contacted by telephone. Levels of pain will be measured before, during and after each trial using standardized visual analog and ordinal pain scales. Measurements from the gait mat and levels of pain relief will be used to determine effectiveness of each type of support. Statisticians will be used to analyze results of the gait mat and pain scale measurements.
