Archaeological excavations at the DK site in the eastern Olduvai Basin, Tanzania, age-bracketed between ∼1.88 Ma (Bed I Basalt) and ∼1.85 Ma (Tuff IB), record the oldest lahar inundation, modification, and preservation of a hominin "occupation" site yet identified. Our landscape approach reconstructs environments and processes at high resolution to explain the distribution and final preservation of archaeological materials at the DK site, where an early hominin (likely Homo habilis) assemblage of stone tools and bones, found close to hominin specimens OH24 and OH56, developed on an uneven heterogeneous surface that was rapidly inundated by a lahar and buried to a depth of 0...

RATIONALE: Complex pelvic ring fracture associated with floating knee is comparatively rare which usually results from high-energy trauma including vehicle-related accidence, falls from height, and earthquake-related injury. To our knowledge, few literatures have documented such injuries in the individual patient. Management of both injuries present challenges for surgical management and postoperative care. The purpose of this study is to prove the feasibility and benefits of damage control orthopedics (DCO)...

This article describes a class of robots-"arthrobots"-inspired, in part, by the musculoskeletal system of arthropods (spiders and insects, inter alia). Arthrobots combine mechanical compliance, lightweight and simple construction, and inexpensive yet scalable design. An exoskeleton, constructed from thin organic polymeric tubes, provides lightweight structural support. Pneumatic joints modeled after the hydrostatic joints of spiders provide actuation and inherent mechanical compliance to external forces...

Potentially, functional electrical stimulation (FES)-assisted exercise may have an important therapeutic role in reducing comorbidities associated with spinal cord injury (SCI). Here, we present an overview of these secondary life-threatening conditions, discuss the rationale behind the development of a hybrid exercise called FES rowing, and describe our experience in developing FES rowing technology. FES rowing and sculling are unique forms of adaptive rowing for those with SCI. The paralyzed leg musculature is activated by multiple channels of electrical pulses delivered via self-adhesive electrodes attached to the skin...

INTRODUCTION: The concomitance of ipsilateral physeal fractures of the distal femur and the proximal tibia is an extremely scarce entity. It is conceptually similar to floating knee in pediatric population. CASE REPORT: One case with this injury is reported in a 16-year-old teenager. He was treated surgically by close reduction and internal fixation. The diagnosis of the tibial fracture was initially missed and the fracture was seen on the post-operative radiographs...

INTRODUCTION: Venous thrombo-embolism (VTE), which consists of deep vein thrombosis (DVT) and pulmonary embolism, is a potentially fatal condition. According to Western literature, DVT of lower limb veins is one of the most common complications following surgeries for lower limb. Few studies have been published from India on the subject and little is known about the true prevalence of the DVT and hence there are no clear guidelines regarding the prophylaxis for DVT for Indian patients...

OBJECTIVE: In the US alone, there are approximately 185 000 cases of limb amputation annually, which can reduce the quality of life for those individuals. Current prosthesis technology could be improved by access to signals from the nervous system for intuitive prosthesis control. After amputation, residual peripheral nerves continue to convey motor signals and electrical stimulation of these nerves can elicit sensory percepts. However, current technology for extracting information directly from peripheral nerves has limited chronic reliability, and novel approaches must be vetted to ensure safe long-term use...

Floating arm injury represents a common yet complicated injury of the childhood severely associated with limb deformation and even morbidity, if not precisely addressed and credibly operated. Here, we report a rare floating upper limb case of a 9-year-old boy with multiple injuries of ipsilateral proximal humeral, supracondylar and distal radial limb. This is the first report to document such a combined floating elbow and floating arm injury in the same limb. In this report, we discuss the surgical procedures used and recovery of the patient monitored to ascertain the effectiveness of the method in limb reorganisation...

OBJECTIVE: To observe the clinical effect of float needle therapy combined with reperfusion activity for pain induced by cyclomastopathy. METHODS: Thirty-five female patients with cyclomastopathy were randomly divided into a comprehensive group (18 cases) and a float needle group (17 cases). In the comprehensive group, float needle manipulation was used at the centre of the biceps brachii belly or the ligature between the affected nipple and breast nodule, about 4 cm beside the exterior margin of the breast, and the reperfusion activity of the affected upper limb and breast was combined...

The control of upper limb neuroprostheses through the peripheral nervous system (PNS) can allow restoring motor functions in amputees. At present, the important aspect of the real-time implementation of neural decoding algorithms on embedded systems has been often overlooked, notwithstanding the impact that limited hardware resources have on the efficiency/effectiveness of any given algorithm. Present study is addressing the optimization of a template matching based algorithm for PNS signals decoding that is a milestone for its real-time, full implementation onto a floating-point digital signal processor (DSP)...

PURPOSE: To show a complication of the use of an Angio-Seal™ closure device. CASE: We present a patient with a systolic murmur in his femoral artery after PCI. The murmur was caused by a dislocated Angio-Seal™, a vascular closure device. This was diagnosed by Doppler Ultrasound. The device was surgically removed. CONCLUSION: Vascular complications, such as lower limb ischemia, requiring surgical intervention tend to be higher after use of a vascular closure device...

OBJECTIVE: We previously demonstrated the usefulness of temporary inferior vena cava filters (t-IVCFs) to prevent pulmonary thromboembolism in pregnant women with deep venous thrombosis (DVT). However, there is currently no consensus on the indications for intrapartum t-IVCF in pregnant women with DVT. In this study, we re-evaluated the safety and usefulness of t-IVCF inserted in this condition. METHODS: A retrospective evaluation in a single center was performed of 45 Japanese patients (54 pregnancies) with DVT between 1989 and 2014...

Radial polydactyly or 'thumb duplication' is the most common congenital upper limb anomaly ('CULA') affecting the thumb. The clinical presentation is highly diverse, ranging from an extra thumb floating on a skin bridge to complicated thumb triplications with triphalangeal, deviating, and hypoplastic components. Radial polydactyly can be classified into one of 7 osseous presentations using the Wassel classification, with type IV (45%), type II (20%), and type VII (15%) occurring most frequently. When faced with a radial polydactyly case, hand surgeons specialised in congenital anomalies must weigh the preoperative functional potential and degree of hypoplasia of both thumbs in order to decide whether to resect one thumb and reconstruct the other ('resection and reconstruction'), excise a central part of both thumbs and unite the lateral tissues into one thumb ('the Bilhaut procedure'), transfer the better-developed distal tissues of one thumb onto the better-developed proximal tissues of the other ('on-top plasty'), or discard both severely hypoplastic thumbs and pollicise the index finger...

A 22-year-old man was admitted to our hospital because of polytrauma following a car accident. The instrumental investigations detected parenchymatous and bone lesions, including a floating elbow (articular distal humerus fracture associated with ipsilateral forearm fracture). After initial temporary stabilization with external fixator and restoration of hemodynamics, we proceeded to the fixation of the upper limb. To reduce local and general risks of complications, a two-stage reconstruction technique has been applied...

Aortic mural thrombi in a normal (non-aneurysmal or minimally atherosclerotic) vessel are an uncommon condition. They are usually located in the descending aorta and, less frequently, in the aortic arch or in the abdominal aorta. The typical clinical presentation is the appearance of symptoms/signs of peripheral arterial embolization, such as lower limb or visceral ischaemia, but these can also be accidentally found in asymptomatic patients. We report the case of a 40-year old man with untreated hypertension and dyslipidaemia admitted to hospital for atypical chest pain associated with an elevation in high-sensitivity troponin T with normal creatine kinase isoenzime MB creatine kinase isoenzyme...
