INTRODUCTION: Despite improvements in revascularization, major amputation remains a significant part of the case-mix in vascular surgical units. These patients tend to be elderly with complex pathology, resulting in poor outcomes and longer lengths of stay (LOS). AIM: This series review provides a description of the patient complexities and outcomes in an Australian cohort undergoing major lower limb amputation for peripheral arterial disease. METHOD: Medical records coded for major amputation between July 2012 and June 2013 in an Australian government funded, tertiary hospital were retrospectively reviewed and descriptively analyzed...

Cognard Type V dural arteriovenous fistulas (dAVFs) are a unique type of cranial vascular malformation characterized by congestion of the perimedullary venous system that may lead to devastating spinal cord pathology if left untreated. The authors present the first known case of a pediatric patient diagnosed with a Type V dAVF. A 14-year-old girl presented with a 3-week history of slowly progressive unilateral leg weakness that quickly progressed to bilateral leg paralysis, sphincter dysfunction, and complete sensory loss the day of her presentation...

Natan Shemer, Amir Degani
This work demonstrates a simple, once per step, flight-phase control method for robots running on a planar unknown rough-terrain environment. The robot used to exemplify these control strategies is the ParkourBot, a Spring-Loaded Inverted Pendulum (SLIP)-based robot. The SLIP model is widely used for the description of humans and animals running motion and has been the basis for many robots. A known control scheme for increasing robustness of the conservative, SLIP model is the Swing Leg Retraction (SLR) method...

BACKGROUND: The defects over the leg, foot and ankle are best covered with a thin pliable flap. The use of muscle flap for the reconstruction of these defects leaves a grafted, aesthetically inferior result. The medial sural artery perforator (MSAP) free flap gives a thin pliable tissue for the reconstruction with better aesthesis. METHODS: The study design was retrospective case analysis over a period of 2 years. All the patients who underwent flap for leg, foot and ankle defect reconstruction in the form of MSAP free flap were included in the study...

BACKGROUND: Periodization is a logical method of organizing training into sequential phases and cyclical time periods in order to increase the potential for achieving specific performance goals while minimizing the potential for overtraining. Periodized resistance training plans are proposed to be superior to non-periodized training plans for enhancing maximal strength. OBJECTIVE: The primary aim of this study was to examine the previous literature comparing periodized resistance training plans to non-periodized resistance training plans and determine a quantitative estimate of effect on maximal strength...

PURPOSE: In many sports, athletes have a preferred leg for sport-specific tasks, such as jumping, which leads to strength differences between both legs, yet the underlying changes in force-generating mechanical properties of the muscle remain unknown. The purpose of this study was to investigate whether the muscle architecture of the medial gastrocnemius (MG) is different between both legs in well-trained jumping athletes and untrained individuals. In addition, we investigated the effect of two ankle joint positions on ultrasound muscle architecture measurements...

Performance metrics such as speed, cost of transport, and stability are the driving factors behind gait selection in legged locomotion. To help understand the effect of gait on the performance and dynamics of small-scale ambulation, we explore four quadrupedal gaits over a wide range of stride frequencies on a 1.43g, biologically-inspired microrobot, the Harvard Ambulatory MicroRobot (HAMR). Despite its small size, HAMR can precisely control leg frequency, phasing, and trajectory, making it an exceptional platform for gait studies at scales relevant to insect locomotion...

BACKGROUND: Leg lengthening occurs in 83% of primary total knee arthroplasty (TKA). The effects of leg length discrepancy (LLD) on THA patients are well established. However, patient function and satisfaction associated with LLD after primary TKA has not been analyzed. This study aimed to quantify the magnitude of limb lengthening, identify radiographic and perceived LLD, and correlate these with predictive factors and functional outcomes in a series of TKA patients. METHODS: Patients undergoing primary TKA who met inclusion criteria were prospectively enrolled in this study...

BACKGROUND: Team sports require rapid whole body change of direction (COD) in order to regain, maintain possession of the ball or to avoid opponent. These actions are often performed through unilateral process, with the contralateral leg incurring no ground contact. As a result, maintaining unilateral dynamic balance remains important. The aim of this study was to examine the relationship between dynamic balance (DB) and (COD) performance in young elite soccer players. METHODS: 20 right-footed young elite soccer players (age=16...

OBJECTIVE The accuracy of robot-guided pedicle screw placement has been proven to be high, but little is known about the impact of such guidance on clinical outcomes such as the rate of revision surgeries for screw malposition. In addition, there are very few data about the impact of robot-guided fusion on patient-reported outcomes (PROs). Thus, the clinical benefit for the patient is unclear. In this study, the authors analyzed revision rates for screw malposition and changes in PROs following minimally invasive robot-guided pedicle screw fixation...
