PURPOSE: The most common complaint lower limb prosthesis users report is inadequacy of a proper socket fit. Adjustments to the residual limb-socket interface can be made by the prosthesis user without consultation of a clinician in many scenarios through skilled self-management. Decision trees guide prosthesis wearers through the self-management process, empowering them to rectify fit issues, or referring them to a clinician when necessary. This study examines the development and acceptability testing of patient-centered decision trees for lower limb prosthesis users...

INTRODUCTION: In vascular surgery the crossover iliofemoral bypass grafting is a well-known surgical technique. In general surgery the repair of an abdominal defect using a Polypropylene mesh is also a standard procedure. A particular technique is defined by the performance of these 2 separate procedures inside a single operation in which the crossover arterial graft is directed from the retroperitoneal space toward the contra-lateral femoral bifurcation through a Polypropylene mesh which closes the musculoaponeurotic layers of the abdominal wall...

INTRODUCTION: Femoral neck fractures are a common occurrence in lower limb amputees. Good post-operative results of hip hemiarthroplasty have been described in below-knee amputees. However, to our knowledge, very few such cases have been reported in above-knee amputees. CASE REPORT: We present a case of a 75-year-old male patient who underwent above-knee amputation of the right lower limb for severe crush injury right leg and a bipolar hemiarthroplasty for an ipsilateral fracture neck of femur sustained in the same road traffic accident...

INTRODUCTION: Mangled upper limb injuries are at surge because of industrialization, modernization, and severe motor vehicle accidents. The utility of various scoring systems are meant for decision making in mangled lower limb injuries, and the same have been extrapolated for mangled upper limb injuries to make a decision of salvage or amputation for the lack of separate scoring system. MATERIALS AND METHODS: We applied mangled extremity severity score (MESS) and mangled extremity syndrome index (MESI) scoring systems to 10 cases of mangled upper limb injuries during the period of November 2010 to September 2012 presented at our tertiary trauma care center...

Restoring locomotion functionality of transfemoral amputees is essential for early rehabilitation treatment and for preserving mobility and independence in daily life. Research in wearable robotics fostered the development of innovative active mechatronic lower-limb prostheses designed with the goal to reduce the cognitive and physical effort of lower-limb amputees in rehabilitation and daily life activities. To ensure benefits to the users, active mechatronic prostheses are expected to be aware of the user intention and properly interact in a closed human-in-the-loop paradigm...

Understanding the characteristics of ground reaction forces (GRFs) on both limbs during sprinting in unilateral amputees wearing running-specific prostheses would provide important information that could be utilized in the evaluation of athletic performance and development of training methods in this population. The purpose of this study was to compare GRFs between intact and prosthetic limbs during sprinting in unilateral transfemoral amputees wearing running-specific prostheses. Nine sprinters with unilateral transfemoral amputation wearing the same type of prosthesis performed maximal sprinting on a 40 m of runway...

A 54-year-old woman diagnosed with multiple sclerosis (MS) at the age of 19 years was scheduled to undergo temporomandibular joint mobilization. She was currently in a remission phase from her MS but with persistent sequelae, including impaired eyesight and muscle weakness of the limbs. In addition, the blood vessels in her upper limbs were compromised by the formation of internal shunts secondary to vascular prosthesis replacements for plasma exchange therapy in MS. After a previous joint mobilization surgery, her temporomandibular joint developed adhesions with resultant trismus...

The positioning of the patient on the fracture table is critical for the successful reduction and operative fixation of intertrochanteric hip fractures. However, this manipulation is challenging with patients who have undergone amputations of their legs. A 97-year-old man presented to the emergency department with symptom of right hip pain following a mechanical fall. He had a below-knee amputation on his right leg following a traffic accident as a 19-year-old and had a below-knee patellar tendon bearing prosthesis fitted to his lower limb for mobility...

A gear-based knee joint is designed to improve the performance of mechanical-type above-knee prostheses. The gear set with the help of some bracing, and bracket arrangement, is used to enable the prosthesis to follow the residual limb movement. The motion analysis and finite-element analysis (FEA) of knee joint components are carried out to assess the feasibility of the design. The maximum stress of 29.74 MPa and maximum strain of 2.393e-004 are obtained in the gear, whereas the maximum displacement of 7...

Myoelectric devices are controlled by electromyographic signals generated by contraction of residual muscles, which thus serve as biological amplifiers of neural control signals. Although nerves severed by amputation continue to carry motor control information intended for the missing limb, loss of muscle effectors due to amputation prevents access to this important control information. Targeted Muscle Reinnervation (TMR) was developed as a novel strategy to improve control of myoelectric upper limb prostheses...

BACKGROUND: Total hip arthroplasty (THA) using dual-mobility (DM) design permits larger hip range of motion. However, it is unclear how it benefits the patients during activities of daily living. The purpose was to compare kinematic variables of the operated limb between THA patients using either DM or single-bearing (SB) implants during a squat task. METHODS: Twenty-four THA patients were randomly assigned to either a DM or SB implant and matched to 12 healthy controls (CTRLs)...

One of the most important factors in successful upper limb prostheses is the socket design. Sockets must be individually fabricated to arrive at a geometry that suits the user's morphology and appropriately distributes the pressures associated with prosthetic use across the residual limb. In higher levels of amputation, such as transhumeral, this challenge is amplified as prosthetic weight and the physical demands placed on the residual limb are heightened. Yet, in the upper limb, socket fabrication is largely driven by heuristic practices...

INTRODUCTION: The rate of cerebrovascular insults is increasing, currently leaving many patients with difficulties to maintain their balance due to muscular weakness and/or poor central control. Those patients are at risk of dislocation when total hip arthroplasty (THA) is planned. Instability remains the most significant issue after primary THA especially in such groups of patients. The risk is more pronounced when other factors are added such as, older age, femoral neck fractures, avascular necrosis and/or hip osteoarthritis...

INTRODUCTION: Deep wound infections in the groin region can result in an acute or life threatening condition. Especially when there is no suitable vein available because of many reasons (e.g. previous surgery, small vessel diameter). Synthetic prosthesis sometimes are not 'first-choice-technique' because of contamination or infection. It was ad hoc hypothesized in an acute setting that a segment of an occluded Superficial Femoral Artery (SFA) could be used as a conduit in combination with eversion technique, known from carotid surgery...

Despite the technological progress in robotics achieved in the last decades, prosthetic limbs still lack functionality, reliability, and comfort. Recently, an implanted neuromusculoskeletal interface built upon osseointegration was developed and tested in humans, namely the Osseointegrated Human-Machine Gateway. Here, we present an embedded system to exploit the advantages of this technology. Our artificial limb controller allows for bioelectric signals acquisition, processing, decoding of motor intent, prosthetic control, and sensory feedback...

PURPOSE: Little data is available on the number of osteosynthesis of limbs in a country. Incidence of osteosynthesis is an essential element for the formation and organization of care. Based on the data from the work of the Hospital Information Technology Agency ( http://www.atih.sante.fr/ ) and available in open access, we wanted to know the incidence of the number of osteosynthesis performed in France and their evolution over ten years between 2006 and 2015. METHODS: The data analyzed are derived from the website of the technical agency of information on the hospitalization (ATIH)...
