Response to clopidogrel in patients undergoing lower extremity revascularization.

Clopidogrel is effective at decreasing cardiovascular events in patients with peripheral artery disease (PAD); however, its effect on limb outcomes are less known. This study investigated the variabil... Three hundred subjects were enrolled in the Platelet Activity and Cardiovascular Events (PACE) study prior to lower extremity revascularization, of whom 104 were on clopidogrel. Light transmission pla... Overall, the median age was 70 (63, 76) and 35.6% were female. Twenty-nine (27.9%) patients experienced MALE during their follow-up. Median aggregation to ADP 2... Among patients undergoing lower extremity revascularization on clopidogrel, higher baseline percent aggregation is associated with increased risk for major adverse limb events....

Outcomes of lower extremity revascularization in octogenarians and nonagenarians for intermittent claudication.

Revascularization for intermittent claudication (IC) due to infrainguinal peripheral arterial disease (PAD) is dependent on durability and expected benefit. We aimed to assess outcomes for IC interven... The Vascular Quality Initiative was queried (2010-2020) for peripheral vascular interventions (PVIs) and infrainguinal bypasses (IIBs) performed to treat IC. Baseline characteristics, procedural detai... There were 84,210 PVIs (12.1% age ≥80 years and 87.9% age <80 years) and 10,980 IIBs (7.4% age ≥80 years and 92.6% age <80 years) for IC. For PVI, patients aged ≥80 years more often underwent femoropo... Octogenarians and nonagenarians have greater perioperative morbidity and long-term ambulatory impairment, limb loss, and mortality after PVI and IIB for claudication. Risks of intervention on elderly ...

Safety and efficacy of intraosseous ropivacaine in lower extremity (SORE) study.

Day stay surgery for anterior cruciate ligament (ACL) reconstructions is an increasingly common practice and has driven clinicians to develop postoperative pain regimes that allow same day mobilizatio... This patient blinded, pilot study randomized 15 patients undergoing ACL reconstruction to receive either IO ropivacaine 1.5 or 2.0 mg/kg; or 300 mg of ropivacaine as local infiltration. The primary ou... All patients in the intervention group receiving IO ropivacaine had plasma concentrations well below the threshold for central nervous system (CNS) toxicity (0.60 μg/mL). The highest plasma concentrat... This study demonstrates that IO ropivacaine is both safe and effective in reducing perioperative pain in patients undergoing ACL reconstruction. There may be scope to increase the IO dose further or u...

Pedobarographic evaluation of five commonly used orthoses for the lower extremity.

Orthoses are designed to achieve immobilization or off-loading of certain regions of the foot. Yet, their off-loading capacity for the specific regions has not yet been studied. Therefore, the aim of ... Five orthoses (postoperative shoe, forefoot relief shoe, short walker boot, high walker boot, and calcaneus fracture orthosis) were compared pedobarographically using insoles on a treadmill to a ready... The forefoot relief shoe, the short- and high walker boot significantly reduced the peak pressure at the forefoot with no significant differences between these orthoses. None of the five orthoses off-... This is the first study to investigate the specific off-loading capacities of different orthoses for specific foot regions in a healthy collective. The knowledge of absolute and relative load shifts f...

Improvement of lower-extremity stability by rotational leg press training.

Previous reports revealed that balance and stability are essential for human physical activity. The present study aimed to evaluate the comparative outcome of a novel beginning movement load training ... Does the leg press training improve the stability of lower extremities?... Twenty adult, asymptomatic and active amateur basketball players were enrolled in this study and randomized in equal numbers into a BMLT group (study group) and a conventional leg press training group... The results after eight-week course of training showed that conventional leg press training had an opposite effect on dynamic stability in the left leg (p = 0.015) and backward movement of the right l... The study group showed better postural stability in terms of the medial/lateral index (p = 0.017), and the athletes in the control group exhibited a significant inability to maintain postural stabilit...

Factors Related to Neuropathic Pain following Lower Extremity Amputation.
