Floating limb

OBJECTIVES: This project aimed to set up a control mechanism for the prevention of pressure injuries during surgery. INTRODUCTION: Structured and comprehensive risk assessment is effective in identifying individuals at risk for pressure injuries. The subsequent use of proper positioning aids (modern gel-filled positioning aids used to position the head and limbs: floating limb concept) reduces the incidence of surgery-related pressure injuries. METHODS: The best practice implementation project used the JBI's Practical Application of Clinical Evidence System and Getting Research into Practice audit tool for promoting change in local healthcare practice...

Introduction An ipsilateral fracture of the femur and tibia (also known as floating knee) is a rare injury in pediatric patients. Recent advances rapidly made the use of intramedullary elastic nails the standard of care in the management of long bone fractures, including floating knee injuries, in patients with immature skeletons. Currently, we have observed a trend of fixing both fractured bones, thus improving functional outcomes, and reducing sequelae. The aim of this study was to report our experience in the management and functional outcomes of floating knee injuries in a single trauma-I level center...

BACKGROUND: The phrase "floating knee is a flail knee joint," referring to ipsilateral femoral and tibial fractures, was first used by Blake and McBryde in 1975. This condition is often caused by a high-energy trauma with often extensive injury to the soft tissues, and is accompanied by life-threatening systemic complications, including head, chest or abdominal injuries and a high incidence of fat embolism. Floating knee is a severe and uncommon injury pattern. CASE SUMMARY: A 27-year-old man sustained multiple injuries when the electric motorcycle he was riding was hit by a van...

BACKGROUND Left ventricular thrombus formation is a serious complication of cardiac diseases and may result in acute embolic events. Early diagnosis and prompt treatment are crucial steps in preventing complications. There is a lack of consensus when it comes to therapy recommendations such as treatment with anticoagulation, thrombolysis, or surgical thrombectomy. CASE REPORT A 74-year-old woman presented with acute peripheral ischemia in the left and right lower limbs. After running a diagnostic workup, we found a history of fatigue and dyspnea in the preceding 2 weeks; and an echocardiographic examination revealed a large floating mass in the left ventricle with a severely reduced LV ejection fraction of 10-15%...

RATIONALE: Floating-dislocated elbow is a severe and extremely rare injury in adults. Reviewing the literature, we found around 6 case reports regarding floating-dislocated elbow in adults. PATIENT CONCERNS AND DIAGNOSES: We report 2 cases of this unusual injury association. Both patients suffered a high energy trauma - fall from a height. Initial X-rays (radiography) revealed in both cases the fractures above and below the elbow (floating elbow) and associated elbow dislocation (floating-dislocated elbow)...

Ipsilateral humerus and forearm fractures, or 'floating elbow,' are high-energy injuries, uncommon in children and usually due to falls or motor vehicle accidents. Early models of washing machines were associated with various reports of upper extremity injuries in children, mostly occurring when the child attempted to remove clothes from a spinning machine. Some of these accidents resulted in serious injuries, including amputation, but have become considerably less common with the introduction of improved safety features in modern appliances...

Restrictive cardiomyopathy (RCM) is a rare disease in children, accounting for <5% of all pediatric cardiomyopathies. It may be idiopathic or may be a secondary to a systemic disease. The disease is characterized by normal systolic function with impaired ventricular filling caused by stiff ventricular walls. Children with RCM often present with symptoms of exercise intolerance, shortness of breath, weakness, and chest discomfort. Thromboembolism events are an unusual presentation of RCM. We are reporting a preadolescent female from the eastern province of Saudi Arabia who presented with sudden right lower limb swelling, paresthesia, and pain caused by a complete occlusion of the terminal part of the abdominal aorta and both common iliac arteries...

OBJECTIVE: Aquatic exercise therapy is used for the treatment and management of chronic low back pain (CLBP). However, to the authors' knowledge, no studies to date have compared muscle activity between different aquatic exercises performed by people with CLBP. As such, this study assessed and compared muscle activity, pain, perceived exertion and exercise intensity between different rehabilitative aquatic exercises. DESIGN: Cross-sectional. SETTING: A 25-m indoor swimming pool within a university building...

BACKGROUND: Floating aortic thrombi (FLOAT) are rare, with very few cases attributed to cocaine use. We report a new case of FLOAT involving the left common carotid artery due to cocaine use, for the first time, complicated with acute ischemic stroke. METHODS: We present in detail our case report, and then, a literature search in PubMed and Scopus was performed up to March 20, 2022, to review the reported cases of aortic thrombus associated with cocaine use. RESULTS: A 39-year-old man with a history of smoking and daily cocaine use was admitted to our stroke unit for acute left-hemispheric symptoms due to carotid-Sylvian occlusion...

BACKGROUND: Innominate artery embolism may result in upper extremity ischemia or stroke. A free-floating thrombus originating from the IA is an unusual and dangerous disorder with embolic potential. Only isolated cases have been described showing different treatment modalities. PURPOSE: To present 3 cases of free-floating thrombus in the IA treated at our institution with 3 different approaches. CASES: The first case is a patient with a free-floating thrombus in the IA treated with cervical debranching and ligation of the proximal right carotid artery; another case of a patient treated with a hybrid approach with deployment of an iliac limb in the IA plus right carotid to subclavian bypass; and a third case of a patient operated by open arch thrombectomy...

INTRODUCTION AND IMPORTANCE: A paediatric floating elbow involves fractures of the supracondylar region of the humerus with ipsilateral fracture of the forearm bones. A floating elbow is very uncommon with an incidence of 3 to 13% of all supracondylar fractures. A concomitant supracondylar and Monteggia fracture is extremely rare with only six cases reported in the literature. CASE PRESENTATION: We present the unusual case of an eight-year-old girl with a concomitant ipsilateral supracondylar humerus fracture and open Monteggia fracture...

A new concept of human-machine interface to control hand prostheses based on displacements of multiple magnets implanted in the limb residual muscles, the myokinetic control interface, has been recently proposed. In previous works, magnets localization has been achieved following an optimization procedure to find an approximate solution to an analytical model. To simplify and speed up the localization problem, here we employ machine learning models, namely linear and radial basis functions artificial neural networks, which can translate measured magnetic information to desired commands for active prosthetic devices...

Rotationplasty is a durable biological reconstruction strategy that is most often performed in children with osteosarcoma of the distal femur. This limb-sparing procedure essentially employs a 180° "rotation" of the distal limb followed by fixation to the proximal limb, resulting in superior functionality and flexibility as compared to those of alternative surgeries. However, despite the many advantages of rotationplasty, literature regarding its indications, techniques, and outcomes in adult patients is scarce...

Simultaneous ipsilateral fractures involving all the bones around the shoulder girdle, namely, the scapula, clavicle and humerus, are rare. We describe an interesting case of a 31-year-old patient who presented after a motor vehicle accident with excruciating pain over his left shoulder and a flail left upper limb. Radiographs and computed tomography (CT) scan revealed the presence of comminuted left scapula, clavicle and proximal humerus fractures. He was also diagnosed with a complete brachial plexus injury of the left shoulder...

Foot-strike and the associated load rate are factors related to overuse injuries in runners. The purpose of this study was to analyse structural and functional changes in runners using floating heel running shoes, compared with runners using conventional footwear. A randomised control trial was conducted. Twenty runners with overuse injuries were followed over a 12-week gait retraining programme using floating heel running shoes or their conventional footwear. Pain was measured with pressure pain thresholds (PPTs), structural changes were measured with ultrasonography, and severity and impact of injury was scored on the Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC-O)...

The induced membrane technique, first described by Masquelet, is a powerful surgical approach that can be used to address segmental bone loss of various aetiologies. Despite ongoing debate regarding optimal delivery, the indications and limits of its application have been tested in increasingly complex situations, highlighting its considerable potential. We present a case of a devastating open lower limb injury with simultaneous femoral and ipsilateral tibial bone loss including articular injury on both sides of the joint...

The jumping motion of legged robots is an effective way to overcome obstacles in the rugged microgravity planetary exploration environment. At the same time, a quadruped robot with a manipulator can achieve operational tasks during movement, which is more practical. However, the additional manipulator will restrict the jumping ability of the quadruped robot due to the increase in the weight of the system, and more active degrees of freedom will increase the control complexity. To improve the jumping height of a quadruped robot with a manipulator, a bio-inspired take-off maneuver based on the coordination of upper and lower limbs is proposed in this paper...

Introduction: Aortic thrombosis is an uncommon condition with serious embolic complications. COVID-19 is currently recognized to be associated with both venous and arterial thrombosis. However, only a limited number of COVID-19 cases associated with aortic thrombosis have been reported in the literature since the beginning of the pandemic. Case presentation: A 66-year-old lady was admitted to our hospital with acute ischemic stroke. Floating aortic arch thrombus was detected incidentally on CT imaging...

Free-floating thrombus in the deep venous system has a high potential to cause pulmonary embolization. It can also be found in patients with superficial venous thrombosis (SVT) that extends to a deep vein. There are still no defined criteria for treatments described in the literature, which range from anticoagulation and fibrinolytic treatments with vena cava filter implants, through open or endovascular thrombectomies, to more invasive procedures such as surgical interruption with ligation of the venous system...

Introduction and Importance: Acute limb ischemia after infrarenal aortic repair is a rare complication, which in mainly described to appear in a short time after surgery.The aim of this paper is to describe a case of a 66-year-old woman who presented at out attention with acute right limb ischemia, one year later an aortic repair for acute abdominal aortic aneurysm rupture. In the best of our knowledge there are no cases of sudden graft occlusion after such long time, described in literature...
