Muscle Oxygen Delivery in the Forearm and in the Vastus Lateralis Muscles in Response to Resistance Exercise: A Comparison Between Nepalese Porters a…
2020
Altitude ascending represents an intriguing experimental model reproducing physiological and pathophysiological conditions sharing hypoxemia as the denominator. The aim of the present study was to investigate fractional oxygen extraction and blood dynamics in response to hypobaric hypoxia and to acute resistance exercises, taking into account several factors including different ethnic origin and muscle groups. As part of the “Kanchenjunga Exploration & Physiology” project, six Italian trekkers and six Nepalese porters took part in a high altitude trek in the Himalayas. The measurements were carried out at low (1,450 m) and high altitude (HA; 4,780 m). Near-infrared spectroscopy (NIRS)-d…
Proximale Verankerung von Hüft-Endoprothesen mit poröser Oberfläche: 6-Jahres-Ergebnisse
2008
PROBLEM The anatomically shaped pcl (ESKA) total hip replacement has a porous coating of the proximal stem and the cup to allow for bony ingrowth. The tip of the stem is polished. METHOD We report the results of 96 THR 6.2 years (5.25-6.7) after implantation. RESULTS There were no revisions during this period. One stem showed radiographic loosening at follow-up. There was stress-shielding in 9.4% in contrast to the concept of proximal fixation. Thigh-pain was found in 9.4%. One patient demonstrated disabling thigh-pain despite radiologic bony ingrowth. By drilling the femur distal to the tip of the stem a remarkable relief was achieved. CONCLUSION Despite numerous cases of stress-shielding …
Greater Trochanteric Pain Syndrome: What is the Meaning?
2011
Greater trochanteric pain syndrome (GTPS) is a common cause of lower extremity pain. This is frequently attributed to trochanteric bursitis and distension of the subgluteal bursae. Patients are suffering from pain radiating to the posterolateral aspect of the thigh, paraesthesiae in the legs, and tenderness over the iliotibial tract. Often the symptoms are mild, with the patient treating himself successfully through activity modification and other conservative measures. including relative rest, ice, compression, elevation, anti-inflammatory medication and treatment modalities such as ultrasound and electrical stimulation, combined with a structured rehabilitation program. Patients whose sym…
Effects of strength and endurance training on thigh and leg muscle mass and composition in elderly women
1995
The effects of 18 wk of intensive strength and endurance training on knee extensor, knee flexor, and lower leg muscle mass and composition were studied in 76- to 78-yr-old women. Muscle cross-sectional area (CSA), lean tissue CSA, and relative proportion of fat were determined using computed tomography. The strength-trained women increased their total muscle lean tissue CSA of the thigh (1.5%; P = 0.035), quadriceps CSA (4.5%; P = 0.021), quadriceps lean tissue CSA (5.8%, P = 0.009), and mean Hounsfield unit of the lower leg muscles (11.2%; P = 0.035) compared with the changes that occurred in the control group during the experiment. The change in quadriceps lean tissue CSA because of the …
Effect of training level and blood flow restriction on thermal parameters: Preliminary study
2016
Abstract Training with blood flow restriction could lead to an effect on skin temperature. Additionally, this effect could be higher in people with lower physical fitness level due to their lower capacity of heat loss. The aim of this preliminary study was therefore to evaluate the effects of training experience on the acute and chronic thermal skin responses after performing exercise with and without blood flow restriction. The study included ten men, of these, five were trained. All subjects performed tests and re-tests for maximum strength (1 repetition maximum) through unilateral leg extensions (right thigh at 45 ± 6.7 kg and left thigh at 45.5 ± 8.1 kg, p > 0.05). The protocol consiste…
Bilateral Iatrogenic Femoral Neuropathy
2015
Dear Editor, Postoperative femoral neuropathy is an uncommon complication associated with pelvic/abdominal surgery. The main mechanism underlying this neuropathy is stretching and/or prolonged compression of the nerve.1,2 The nerve compression can be caused by the self-retaining retractors that are sometimes used during surgery directly constricting the nerve against the pelvic sidewall and inducing ischemia.1 Symptoms of femoral neuropathy are weakness of ipsilateral hip flexion and knee extension, and sensory deficit on the anteromedial thigh. The prognosis is generally good, with partial or complete recovery being common. Postoperative femoral neuropathy is generally unilateral2,3,4; bil…

Muscle versus Fasciocutaneous Flap in Lower Limb Reconstruction: Is There a Best Option?
2017
AbstractSoft tissue defects of the lower extremity that expose underlying bones, joints, and tendons pose challenging problems and generally require free tissue transfer for a successful reconstruction. Historically, muscle flaps were the gold standard choice for lower limb reconstruction. To obviate the unpredictable appearance and high donor-site morbidity of muscle flaps, fasciocutaneous flaps were introduced. Recently, perforator flaps, such as the anterolateral thigh flap, gained a leading role in the reconstructive scenario. There is growing evidence in the literature supporting that fasciocutaneous and perforator flaps are comparable to muscle flaps in terms of flap survival, postope…
Urethral Reconstruction in Anterolateral Thigh Flap Phalloplasty: A 93-Case Experience
2019
BACKGROUND: Urethral reconstruction in anterolateral thigh flap phalloplasty cannot always be accomplished with one flap, and the ideal technique has not been established yet. In this article, the authors' experience with urethral reconstruction in 93 anterolateral thigh flap phalloplasties is reported. METHODS: Ninety-three anterolateral thigh phalloplasties performed over 13 years at a single center were retrospectively reviewed to evaluate outcomes of the different urethral reconstruction techniques used: anterolateral thigh alone without urethral reconstruction (n = 7), tube-in-tube anterolateral thigh flap (n = 5), prelaminated anterolateral thigh flap with a skin graft (n = 8), antero…
The "critical zones" of entrapment of the nerves of the lower limb.
1991
The author has studied, in a group of 40 dissections on cadavers of individuals of different ages, the main “critical zones” of entrapment of some terminal branches of the lumbo-sacral plexus, which include canals (fibrous, osteo-fibrous, fibro-muscular), intervals (intermuscular, fibro-muscular, musculo-ligamentous), rings (fibrous or fibro-muscular) and foramina. They provide the topographical anatomical basis for possible compressive phenomena of the nerves of the lower limb.
