Gait abnormalities reported in childhood Charcot-Marie-Tooth disease (CMT) include foot-drop, reduced ankle power at push-off and increased knee and hip flexion for swing clearance ('steppage-gait'). The purpose of this study was to describe the gait patterns of 60 children aged 6-17 years with CMT (CMTall) and distinguish differences based on functional weakness using the CMT Pediatric Scale (CMTPedS). Data were captured using Vicon Nexus system and compared to 50 healthy norms. Data were subdivided into three groups denoting increasing severity of dorsiflexion and plantarflexion weakness from the CMTPedS: no difficulty heel or toe walking (CMTND), difficulty heel walking (CMTDH), difficulty toe and heel walking (CMTDTH)...

A detailed description of the kinematics and kinetics of the ankle, midtarsal and metatarsophalangeal joints of the feet of a healthy adult male population during barefoot walking is provided. Plots of the angles and moments in each plane during the stance phase are reported, along with the mean and standard deviation values of 87 different parameters that characterise the 3D dynamics of the foot joints. These parameters were used to check for similarities between subjects through a hierarchical analysis that allowed three different gait patterns to be identified, most of the differences corresponding to the frontal and transverse planes...

The ankle and foot are commonly injured during sporting activities. Clinical diagnosis can at times be challenging, due to the complex anatomy and multiple sites of potential injury. In the athlete, there is a reduced threshold for imaging to clarify diagnosis, guide prognosis, and treatment. Diagnostic imaging is also helpful in evaluating ongoing symptoms in the subacute or chronic setting. (©) RSNA, 2017.

Jyoshid R Balan
BACKGROUND: The defects over the leg, foot and ankle are best covered with a thin pliable flap. The use of muscle flap for the reconstruction of these defects leaves a grafted, aesthetically inferior result. The medial sural artery perforator (MSAP) free flap gives a thin pliable tissue for the reconstruction with better aesthesis. METHODS: The study design was retrospective case analysis over a period of 2 years. All the patients who underwent flap for leg, foot and ankle defect reconstruction in the form of MSAP free flap were included in the study...

The nervous system integrates visual input regarding obstacles with limb-based sensory feedback to allow an individual to safely negotiate the environment. This latter source can include cutaneous information from the foot, particularly in the event that limb trajectory is not sufficient and there is an unintended collision with the object. However, it is not clear the extent to which cutaneous reflexes are modified based on visual input. In this study, we first determined if phase-dependent modulation of these reflexes is present when stepping over an obstacle during overground walking...

BACKGROUND: Isolated lateral malleolar fractures may result from a supination-external rotation (SER) injury of the ankle. Stable fractures maintain tibiotalar congruence due to competent medial restraints and can be treated nonoperatively with excellent functional results and long-term prognosis. Stability might be assessed with either stress radiographs or weightbearing radiographs. METHODS: A consecutive series of patients with closed SER fractures (presumed AO 44-B1) were prospectively enrolled from 2008 to 2015...

Chaput tubercle fracture occurs at the antero-lateral position of the distal tibia in adult as a counterpart of adolescent Tillaux fracture. It is a case of adult male which presented to us with onset of acute pain, swelling and restricted movements of ankle after a road side accident. A clinical diagnosis of Chaput tubercle fracture was established after a CT-scan. The displaced fracture was managed by open reduction and internal fixation by screw. At the end of follow up, the foot and ankle ability score measured...

BACKGROUND: Reconstruction of soft-tissue defects in lower third of leg, ankle, and foot has been a challenge and reconstructive surgeons have been trying to innovate different flaps. To solve this issue, we propose a distally based sural artery peroneus flap (DBSPF) in which we include superficial portion of the peroneus brevis muscle and its blood supply with the peroneal artery distally. The aim of this study was to evaluate the functional outcome and its usefulness over conventional distal sural artery flap or other local options available...

OBJECTIVE: To assess whether foot and/or ankle symptoms are associated with an increased risk of worsening of knee pain and radiographic change in people with knee osteoarthritis (OA). METHODS: The presence and laterality of foot/ankle symptoms were recorded at baseline in 1368 participants from the Osteoarthritis Initiative with symptomatic radiographic knee OA. Knee pain severity (measured using the Western Ontario and McMaster Universities Osteoarthritis Index pain subscale) and minimum medial tibiofemoral joint space (minJSW) width measured on x-ray were assessed yearly over the subsequent four years...

BACKGROUND: Ankle impingement is a common cause of chronic ankle pain. We retrospectively studied the effectiveness of ultrasound-guided percutaneous needle fenestration of the pathological soft tissues combined with corticosteroid injection to treat this condition. METHODS: We administered a telephone survey to patients who underwent the procedure. Patients were asked questions on the Foot Function Index and queried about their overall satisfaction with the procedure on a scale of 0 (completely unsatisfied) to 10 (very satisfied)...

BACKGROUND: In a patient with severe hemiplegia, the risk of the knee giving way is high during the early stage of gait exercise with an ankle-foot orthosis. However, use of a knee-ankle-foot orthosis has many problems such as large amount of assistance and compensatory motions. To resolve these problems, we have engaged in the development of the Gait Exercise Assist Robot (GEAR). OBJECTIVE: To evaluate the improvement efficiency of walk with GEAR in a stroke patient...

BACKGROUND: Robotic driven treatment plans targeting isolated joints of the upper limb have improved the sensorimotor condition of patients with stroke. Similar intensive efforts to allay lower limb gait impairment have not been so successful. In patients with stroke, targeted robot assisted training of the ankle joint, in a seated position, has demonstrated significant alterations in ankle stiffness and foot-ankle orientation at foot strike which may provide a new treatment option for gait impairment...

OBJECTIVE: Biomechanical data from post mortem human subject (PMHS) experiments are used to derive human injury probability curves and develop injury criteria. This process has been used in previous and current automotive crashworthiness studies, Federal safety standards, and dummy design and development. Human bone strength decreases as the individuals reach their elderly age. Injury risk curves using the primary predictor variable (e.g., force) should therefore account for such strength reduction when the test data are collected from PMHS specimens of different ages (age at the time of death)...

Myopericytoma is a benign tumor of concentrically distributed perivascular myoid cells. Its molecular basis and relationship with myofibroma/myofibromatosis and other pericytic tumors are not fully understood. In our consultation/surgical files of over 1000 myopericytic lesions, we identified 11 cases with diffuse dermal/subcutaneous involvement by microscopic myopericytomatous nodules, a phenomenon we have termed myopericytomatosis. Myopericytomatosis affected mostly adults (female:male=8:3; median age, 37 y; range, 9 to 63 y) in the lower extremities (foot/ankle, 5; calf, 3; knee, 1; thigh, 1; neck, 1) over months to 25 years, ranging from 1...

Rigid ankle-foot orthoses (AFO) are commonly used for impeding foot drop during the swing phase of gait. They also reduce pain and improve gait kinematics in patients with weakness or loss of integrity of ankle-foot complex structures due to various pathological conditions. However, this comes at the price of constraining ankle joint mobility, which might affect propulsive force generation and balance control. The present study examined the effects of wearing an AFO on biomechanical variables and electromyographic activity of tibialis anterior (TA) and soleus muscles during gait initiation (GI)...

The management of displaced, intra-articular calcaneal fracture represents a surgical challenge to even an experienced orthopedic surgeon. Plate osteosynthesis using an extended lateral approach is complicated by soft tissue problems, while those treated by closed reduction and percutaneous pinning cannot address all the intra-articular fragments sufficiently. The objective of our study is to evaluate restoration of subtalar joint and long-term functional outcomes in intra-articular displaced calcaneal fractures treated with transverse subcondral screws through a small incision on lateral aspect of calcaneus and percutaneously placed axial screws through the calcaneal tuberosity...
