Background and Aims: Routine use of pre-procedural ultrasound guided midline approach has not shown to improve success rate in administering subarachnoid block. The study hypothesis was that the routine use of pre-procedural (not real time) ultrasound-guided paramedian spinals at L5-S1 interspace could reduce the number of passes (i.e., withdrawal and redirection of spinal needle without exiting the skin) required to enter the subarachnoid space when compared to the conventional landmark-guided midline approach...

In addition to the fibularis longus and brevis muscles, a number of anomalous muscles or tendons can arise from the lateral compartment of the leg. The authors describe a bilateral and robust fibularis digiti quinti (FDQ) tendon present in the foot of a 99-year-old female cadaver, present the incidence of this tendon in a cohort of 26 cadavers dissected by podiatric-medical students for a lower-extremity anatomy course, and discuss the anthropological and clinical significance of the findings. In these specimen, the FDQ tendon arose from the fibularis brevis tendon proximal to the lateral malleolus, but did not separate completely from the fibularis brevis tendon until passing through the inferior fibular retinaculum...

A limited number of studies have explored lower-limb biomechanics during high-heeled jogging and running, and most studies have failed to clarify the wearing experience of subjects. This protocol describes the differences in lower-limb kinematics and ground reaction force (GRF) between experienced wearers (EW) and inexperienced wearers (IEW) during moderate high-heeled jogging and running. A three-dimensional (3D) motion analysis system with a configured force platform was used to synchronously capture lower-limb joint movements and GRF...

Aims To report on great saphenous vein diameter distribution of patients undergoing endovenous laser ablation for lower limb varicose veins and the ablation technique for large diameter veins. Methods We collected retrospective data of 1929 (943 left leg and 986 right leg) clinically incompetent great saphenous vein diameters treated with endovenous laser ablation over five years and six months. The technical success of procedure, complications and occlusion rate at short-term follow-up are reported. Upon compression, larger diameter veins may constrict asymmetrically rather than concentrically around the laser fibre (the 'smile sign'), requiring multiple passes of the laser into each dilated segment to achieve complete ablation...

PURPOSE: There is direct literature conflict regarding coronal plane contracture or laxity in the end-stage varus osteoarthritic knee. Understanding the preoperative soft tissue status is important for optimizing the soft tissue envelope during total knee arthroplasty (TKA). METHODS: The lower limb was manipulated using computer navigation, prior to surgical releases, to allow the limb weight-bearing axis to pass through the knee centre in maximum extension and 20° of flexion...

The studies presented were designed to highlight the impact of pancreatic enzymes on glycemic control and insulin response. Blood glucose and plasma insulin levels were monitored after intravenous, oral or direct gut glucose tolerance tests (GTT) in 6 pigs with an intact gastrointestinal tract and in 12 pigs following duodenal-jejunal bypass (DJB) surgery. In the intact pigs, pancreatic enzymes (Creon®) given orally 1 h prior to the GTT, lowered the blood glucose levels during the oral and meal GTT and reduced the plasma insulin response during the intravenous and meal GTT...

Division of nerves close to their origin and muscular entrapments by nerves in the limbs is not very common. Femoral nerve is the largest branch of the lumbar plexus and arises from dorsal divisions of ventral rami of L2 to L4 spinal nerves. During routine cadaveric dissection for first year medical students at Melaka Manipal Medical College (Manipal Campus), Karnataka, India, we observed a variation in the division and course of left femoral nerve in about 65-year-old male cadaver. The femoral nerve was split into two divisions above the inguinal ligament after its origin from the lumbar plexus...

BACKGROUND: Brazilian Jiu-Jitsu (BJJ) athletes can be divided into two combat styles: pass fighters (PFs) and guard fighters (GFs). Flexibility of the posterior chain muscles is highly necessary in these athletes, especially in GFs. On the other hand, isometric strength of the trunk extensors is required in PFs. Handgrip strength is important in holding the kimono of the opponent, and symmetrical lower-limb strength is important for the prevention of injuries due to the overload caused by training...

The present research aimed to analyze values of the autocorrelation function measured for different time values of ground reaction forces during stable upright standing. It was hypothesized that if recording of force in time depended on the quality and way of regulating force by the central nervous system (as a regulator), then the application of autocorrelation for time series in the analysis of force changes in time function would allow to determine regulator properties and its functioning. The study was performed on 82 subjects (students, athletes, senior and junior soccer players and subjects who suffered from lower limb injuries)...

Autosomal dominantly inherited mutations of BICD2 are associated with congenital-onset spinal muscular atrophy characterised by lower limb predominance. A few cases have also showed upper motor neuron pathology, including presenting with features resembling hereditary spastic paraplegia. The age-of-onset for the published families is usually at birth but also included cases with childhood- and adult-onset disease. In this report we described two isolated probands that presented in utero with features associated with reduced fetal movements...

The adductor canal compression syndrome is one of the several rare nontraumatic causes of arterial occlusions, which may lead to critical ischemia of the lower limb. We report the case of a 46-year-old athletic woman, who suffered from activity-related paresthesia and sharp pain in the left upper and lower leg for 2 years. Imaging and neurological investigations of the spine remained without pathological findings that would explain the patient's complaints. Actually, the patient presented with symptoms of critical lower limb ischemia...
