BACKGROUND: Sleep dysfunction is a common and disabling non-motor symptom in Parkinson's disease. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) improves motor symptoms and subjective sleep in PD, but alternative stimulation parameters to optimize sleep have not been explored. We hypothesized that low frequency STN DBS would improve objective sleep more than conventional settings. METHODS: Twenty PD subjects with STN DBS (18 unilateral, 2 bilateral) underwent 3 non-consecutive nights of polysomnography: DBS off; DBS high frequency (≥130 Hz); and DBS low frequency (60 Hz)...

OBJECTIVE: Percutaneous endoscopic contralateral interlaminar lumbar foraminotomy (PECILF) for lumbar degenerative spinal stenosis is an established procedure. Better preservation of contralateral facet joint compared to that of the approach side has been demonstrated with uniportal bilateral decompression. The aim of this retrospective case series was to analyze the early clinical and radiological outcomes of standalone contralateral foraminotomy and lateral recess decompression using PECILF...

In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment of the femoral component in total knee arthroplasty (TKA). There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittal femoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cortical line (DACL) were measured. Finally, the correlation of component alignment and SFB was examined. Mean SFB was 7±2.7 degrees. The component was in flexion position in relation to mechanical axis and DACL as 8...

Peripheral nerve tumours (PNTs) affecting the limbs may lead to chronic pain, lameness and/or monoparesis that is refractory to medical treatment. The most common radical therapy for PNTs has been surgical excision with limb amputation. However, compartmental resection with preservation of the limb has been performed by the authors with favourable clinical results and therefore this bi-institutional retrospective study was undertaken to assess limb function, survival and recurrence. Sixteen dogs that had been diagnosed with PNTs between 1995 and 2011 met the inclusion criteria for this study...

Cellulitis is a frequent soft tissue and skin infection. The lower limbs are affected in 70 to 80% of cases. Cellulitis in aged persons is not yet well described in literature. A retrospective descriptive study conducted in the Internal Medicine Department of Sahloul hospital in Sousse in Tunisia. It included patients whose age was up to 65 years old admitted into hospital for cellulitis of the legs, the arms or the face. One hundred fifty eight patients with a mean age of 73 years old (range: 65 to 94 years old) were included...

INTRODUCTION: Major lower limb amputation significantly increases the energy cost of walking for patients. Complications such as osteomyelitis may require further surgery, and can lead to shortening of the stump. In these cases, the aim should be to treat infection without shortening the limb further. We present a series of patients with established osteomyelitis of the amputation stump, managed using a modified Lautenbach technique. METHOD: Six patients with either above or below knee amputations, in the practice of a single orthopaedic surgeon, were studied...

BACKGROUND AND OBJECTIVE: Performing limb salvage with safe margins and preserving meaningful function is very difficult in the setting of primary malignant bone and soft tissue tumors due to the complex and constrained anatomy of the foot and ankle. The study aims to evaluate the efficacy of limb salvage procedures in terms of functional and oncological outcomes. METHODS: Clinical data of 48 patients, who underwent surgical treatment between 1992 and 2015 in our institution, were retrospectively analyzed...

Aging is a major factor in the decline of limb blood flow with ischemia. However, the underlying mechanism remains unclear. We investigated the role of mitochondrial reactive oxygen species (ROS) with regard to limb perfusion recovery in aging during ischemia. We performed femoral artery ligation in young and old mice with or without treatment with a scavenger of mitochondrial superoxide, MitoTEMPO (180 μg/kg/day, from pre-operative day 7 to post-operative day (POD) 21) infusion using an implanted mini-pump...

Previous zooarchaeological analysis at Koobi Fora indicates that Okote Member hominins were the primary agents of bone assemblage formation, gained early access to large and small mammal flesh, and consumed both high- and low-ranked carcass parts. The discovery of additional butchered specimens prompted the re-analysis presented here of three large and well-preserved zooarchaeological assemblages from the Okote member, GaJi14, FwJj14N and FwJj14S, to revisit paleoecological hypotheses about tool-assisted carnivory...

The extinct ocean-going plesiosaurs were unique within vertebrates because they used two flipper pairs identical in morphology for propulsion. Although fossils of these Mesozoic marine reptiles have been known for more than two centuries, the function and dynamics of their tandem-flipper propulsion system has always been unclear and controversial. We address this question quantitatively for the first time in this study, reporting a series of precisely controlled water tank experiments that use reconstructed plesiosaur flippers scaled from well-preserved fossils...

PURPOSE: Limb salvage surgery is increasingly used for the treatment of distal femur bone sarcomas. Total knee replacement using megaprosthesis and epiphysis-sparing biologic reconstruction using an allograft are widely used in order to preserve joint motion. We aimed to compare the results of these procedures using gait analysis in patients undergoing limb salvage surgery. METHODS: Fifteen patients were included, nine undergoing allograft with epiphysis sparing (Allograft group) and six undergoing megaprosthesis (Megaprosthesis group)...

OBJECTIVE: An association has been found between abdominal obesity and functional capacity (FC) in the literature where waist circumference has been used to infer abdominal obesity. However, most studies focused on evaluating predictors of FC and functional disabilities only in sedentary people. This study aimed to examine whether abdominal obesity is associated with FC in physically active postmenopausal women. METHODS: Forty-four active (>7,500 steps/d) postmenopausal women were recruited...

BACKGROUND: Hepaticojejunostomy may be used for biliary reconstruction in certain cases of liver transplantation. In this occasion, Roux-en-Y biliary reconstruction is predominantly performed. Petersen's hernia is an internal hernia that can occur after Roux-en-Y reconstruction, and it may lead to extensive ischemic changes affecting incarcerated portions of the small bowel or Roux limb resulting in severe complications with a poor prognosis. CASE PRESENTATION: The present case was a 44-year-old male who underwent living donor liver transplantation (LDLT) for familial amyloid polyneuropathy and in whom biliary reconstruction was performed with Roux-en-Y hepaticojejunostomy...

INTRODUCTION: Achondroplasia is the most common form of dwarfism in humans and is orthopedically characterized by shortened extremities and an exaggerated lumbar lordosis. The surgical challenges are maintenance of axial alignment during limb lengthening as well as joint preservation and alignment restoration. CASE REPORT: We present a 46-year-old female suffering from achondroplasia with severe pain in both knees. Severe varus deformities of both femurs and degeneration of both knee joints became apparent on clinical and radiological examination...

Robotics is increasing in popularity as a method of providing rich, personalized and cost-effective physiotherapy to individuals with some degree of upper limb paralysis, such as those who have suffered a stroke. These robotic rehabilitation systems are often high powered, and exoskeletal systems can attach to the person in a restrictive manner. Therefore, ensuring the mechanical safety of these devices before they come in contact with individuals is a priority. Additionally, rehabilitation systems may use novel sensor systems to measure current arm position...

Tim Ramczykowski, Thomas A Schildhauer
Despite modern conservative and surgical procedures, the number of amputations of the lower limb remains at a consistently high level. With the demographic changes and the consequent prevalence of atherosclerosis and diabetes mellitus, there is a steady increase of the risk factors that can lead to an amputation. The cause, which ultimately leads to the loss of the affected limb is therefore a symptom of the underlying disease. Primarily, the purpose of any medical treatment is the prevention of any amputation...
