BACKGROUND AND OBJECTIVES: Adductor canal blocks (ACBs) are associated with improved analgesia, preserved quadriceps strength, and decreased length of hospitalization after total knee arthroplasty (TKA). However, controversy remains regarding the ideal location of a continuous block within the adductor canal, and it remains unclear whether similar clinical benefits are obtained irrespective of block location. In this randomized, double-blind, noninferiority study, we hypothesized that a continuous proximal ACB provides postoperative analgesia that is no worse than a continuous distal ACB...

RATIONALE: Inflammatory myofibroblastic tumor (IMT) is a neoplasm of low malignant potential. The most frequent site of IMT is in the lung, whereas recurrent and metastasis of thyroid IMT has been seldom reported. PATIENT CONCERNS: A 57-year-old male presented with a 3-year history of painless thyroid mass. The physical examination revealed a diffusely enlarged thyroid which was firm. The thyroid function and antibodies were normal. Thyroid ultrasound revealed a hypoechoic mass in the left lobe and heterogeneous echo in the right lobe...

BACKGROUND: Developmental dysplasia of the hip (DDH) diagnosed in older postnatal children can be effectively treated by closed reduction (CR) alone. However, no prospective or comparative trial to explore the differential effectiveness of CR between non-walking and walking postnatal children has yet been reported. This study investigated the clinical and radiologic outcomes of CR in the age range of interest (12-18 months old) via a prospective trial and compared these results with those of a younger age group who also underwent CR...

INTRODUCTION: Managing postoperative pain can be challenging for arthroplasty surgeons. While pain control modalities, such as adductor canal blockade (ACB), have been proven effective, the multifactorial nature of pain perception may serve as an obstacle for optimizing pain control. This study assesses the effect of patient pre-operative physical status on patient perception of pain. Specifically, we compared 1) lengths of hospital stay (LOS), 2) pain levels, and 3) opioid consumption in patients receiving total knee arthroplasty (TKA) who presented with an American Society of Anesthesiologists physical status score (ASA) of 2 and 3...

Cruveilhier described in 1834 the human flexor pollicis brevis (FPB), a muscle of the thenar compartment, as having a superficial and a deep head, respectively, inserted onto the radial and ulnar sesamoids of the thumb. Since then, Cruveilhier's deep head has been controversially discussed. Often this deep head is confused with Henle's "interosseous palmaris volaris" or said to be a slip of the oblique adductor pollicis. In the 1960s, Day and Napier described anatomical variations of the insertions of Cruveilhier's deep head, including its absence, and hypothesized, that the shift of the deep head's insertion from ulnar to radial facilitated "true opposability" in anthropoids...

Although limb girdle weakness is not part of the major diagnostic criteria of oculopharyngeal muscular dystrophy (OPMD), it has frequently been observed in the Dutch and other OPMD cohorts. In the Dutch cohort, this might be related to the relatively old age or the severity of the genetic defect. This patient-control study (14 OPMD patients and 12 controls) investigated the involvement of limb girdle muscles with a multidimensional approach in early OPMD. We assessed functional abilities, disease impact, physical activity, muscle strength, histopathology and fatty infiltration using questionnaires, actometer, functional tests, manual and quantitative muscle testing, muscle biopsy and muscle MRI...

PURPOSE: We aim to retrospectively evaluate patients with non-ossifying fibroma (NOF) of the distal femur by radiographs, CT and MRI, and to provide a theory describing the reasoning for the distal femur NOF's location and aetiology. METHODS: Charts of patients with NOFs between 2003 and 2014 were retrospectively reviewed. Inclusion criteria encompassed a diagnosis of NOF of the distal femur by imaging, and histologically, if available. Radiographs, CT and MRI were used to characterise the relationship of the NOF lesions with the surrounding soft tissues...

PURPOSE: Progressive hip displacement is one of the most common orthopaedic pathologies in children with cerebral palsy (CP). Reconstructive hip surgery has become the standard treatment of care. Reported avascular necrosis (AVN) rates for hip reconstructive surgery in these patients vary widely in the literature. The purpose of this study is to identify the frequency and associated risk factors of AVN for reconstructive hip procedures. METHODS: A retrospective analysis was performed of 70 cases of reconstructive hip surgery in 47 children with CP, between 2009 and 2013...

The purpose of the study is to establish absolute reliability and concurrent validity between hand-held dynamometers (HHDs) and isokinetic dynamometers (IDs) in lower extremity peak torque assessment. Medline, Embase, CINAHL databases were searched for studies related to psychometric properties in muscle dynamometry. Studies considering standard error of measurement SEM (%) or limit of agreement LOA (%) expressed as percentage of the mean, were considered to establish absolute reliability while studies using intra-class correlation coefficient (ICC) were considered to establish concurrent validity between dynamometers...

Coordination of respiratory pump and valve muscle activity is essential for normal breathing. A hallmark respiratory responses to hypercapnia and hypoxia is the emergence of active exhalation, characterized by abdominal muscle pumping during the late one-third of expiration (late-E phase). Late-E abdominal activity during hypercapnia has been attributed to the activation of expiratory neurons located within the parafacial respiratory group (pFRG). However, the mechanisms that control emergence of active exhalation, and its silencing in restful breathing, are not completely understood...

The skeleton of the jaws and neurocranium of sturgeons (Acipenseridae) are connected only through the hyoid arch. This arrangement allows considerable protrusion and retraction of the jaws and is highly specialized among ray-finned fishes (Actinopterygii). To better understand the unique morphology and the evolution of the jaw apparatus in Acipenseridae, we investigated the development of the muscles of the mandibular and hyoid arches of the Siberian sturgeon, Acipenser baerii. We used a combination of antibody staining and formalin-induced fluorescence of tissues imaged with confocal microscopy and subsequent three-dimensional reconstruction...

BACKGROUND: Adductor canal block (ACB) has emerged as an effective analgesic regional technique for major knee surgeries in the last decade. Its motor-sparing properties make it particularly attractive for ambulatory knee surgery, but evidence supporting its use in ambulatory arthroscopic knee surgery is conflicting. This systematic review and meta-analysis evaluates the analgesic effects of ACB for ambulatory arthroscopic knee surgeries. METHODS: We conducted a comprehensive search of electronic databases for randomized controlled trials examining the analgesic effects of ACB compared to control or any other analgesic modality...

Human walking can be viewed essentially as a continuum of anterior balance loss followed by a step that re-stabilizes balance. To secure balance an extended base of support can be assistive but healthy young adults tend to walk with relatively narrower steps compared to vulnerable populations (e.g. older adults and patients). It was, therefore, hypothesized that wide step walking may enhance dynamic balance at the cost of disturbed optimum coupling of muscle functions, leading to additional muscle work and associated reduction of gait economy...

Paired corticospinal-motoneuronal stimulation (PCMS), which delivers repeated pairs of transcranial magnetic stimuli (TMS) and maximal motor nerve stimuli, can alter corticospinal transmission to low threshold motoneurones in the human spinal cord. To determine whether similar changes occur for high threshold motoneurones, we tested whether maximal voluntary activation and force can be affected by PCMS in healthy individuals. On two separate days, healthy participants (n=14) performed brief thumb adduction MVCs before and after a control protocol (TMS only) or PCMS designed to facilitate corticospinal transmission to adductor pollicis...

Mikrocytos mackini is an intracellular parasite of oysters and causative agent of Denman Island disease in Pacific oysters Crassostrea gigas. Although M. mackini has been investigated for decades, its natural mode of transmission, mechanism for host entry, and environmental stability are largely unknown. We explored these biological characteristics of M. mackini using a recently described quantitative PCR (qPCR) assay. We detected M. mackini in the flow-through tank water of experimentally infected oysters and during disease remission in host tissues following 6 wk of elevated water temperature...

Adductor canal block (ACB) is an effective analgesic alternative to femoral nerve block after total knee arthroplasty (TKA). The aim of the present study was to investigate whether addition of dexamethasone to ropivacaine for ACB is able to prolong analgesia and reduce pain. Study participants were randomized into groups receiving ACB with either 0.5% ropivacaine + normal saline (control group; n=93) or 0.5% ropivacaine + 8 mg dexamethasone (dexamethasone group; n=93). All patients were subjected to identical peri-operative management...

Displaced ulnar collateral ligament injuries of the metacarpophalangeal joint of the thumb, also known as Stener lesions, are a well-recognized clinical entity, requiring surgical intervention because of the trapped location of the torn lateral collateral ligament superficial to the adductor aponeurosis of the thumb. We report a similar lesion located at the first metatarsophalangeal joint, to our knowledge the first ever described in the literature. In our patient, magnetic resonance imaging showed a full-thickness tear of the lateral collateral ligament of the first metatarsophalangeal joint, as well as a full-thickness tear of the extensor hood, with dislocation of the proximal part of the ruptured lateral collateral ligament to a position superficial to the extensor hood...
