The design of patient specific weight-bearing exercises after the surgical implementation of internal fixations is of critical importance for bone fracture healing. The purpose of this study is to theoretically investigate the effects of physiologically relevant dynamic loading on early stage of fracture healing under different locking compression plate (LCP) configurations. The finite element results show that dynamic loading enhanced transport of bone cells and growth factors in the fracture callus is much dependent on the flexibility of LCP...

PURPOSE: Distal clavicle fractures are divided into three types according to Neer's classification. These fractures are usually treated with a sling to immobilize the upper extremity, however, the treatment of type 2 fractures remain controversial. We focused on the anatomical basis of these fractures in which disruptions in the conoid ligament led to the distraction between the two bony fragments. In this study, we report an arthroscopic procedure for conoid ligament reconstruction and its therapeutic outcomes, and discuss the function of the reconstructed conoid ligament...

BACKGROUND: Functional range of motion is defined as the required range of motions for individuals to maintain maximal independence, along with optimal conditions for activities of daily living. Intervention plans for rehabilitation are directed towards the acquisition of anatomical range of motion. However, this isn't always possible based on person's etiology, prognosis, or severity of disease. RESEARCH QUESTION: The aim of this study is to determine functional range of motion during different unilateral, bilateral symmetrical and bimanual asymmetrical tasks of activities of daily living...

BACKGROUND: Systemic mast cell activation disease (MCAD, prevalence 5-10%) is a multifactorial, polygenic disease with multisystemic symptoms that is characterized by an unregulated increased release of mast cell mediators and an accumulation of activated mast cells potentially in all organs and tissues. Due to the high prevalence of the disease, physicians involved in surgical, anesthesiological and interventional procedures are often unknowingly faced with MCAD patients experiencing unexpected preoperative, intraoperative and postoperative complications, if no mast cell-specific treatment regimens have been applied...

Aim of this paper is to allows to analyze a topic of great relevance and media interest such as the role of prophylactic mastectomy in healthy women with BRCA mutation proposing to the surgeons some useful informations for decision-making. Less than 15% of all breast cancers are associated with germline genetic mutations. The majority of hereditary breast tumors are due to mutations in BRCA1 and BRCA2 genes that are responsible for only one third of hereditary cases. The risk estimates are extremely heterogeneous with a mean cumulative lifetime breast cancer risk of approximately 72% in BRCA1 and 69% in BRCA2 by age 80...

BACKGROUND: The anterior temporal approach (ATA) has been reported as suitable for surgical clipping of posteriorly projecting internal carotid artery (ICA) aneurysms. However, since the ICA follows a variable course, tortuosity of the ICA may affect visualization of the aneurysm. The present study investigated the impact of the intracranial course of the ICA and aneurysm projection on surgical approach. METHODS: Consecutive patients with posterior communicating artery (PCoA) aneurysm treated with clipping at our hospital between May 2015 and April 2018 were retrospectively reviewed...

BACKGROUND: Current surgical interventions for the femoral neck fracture are using either cannulated screws (CCS) or a single large screw at a fixed angle with a side-plate (i.e., a sliding hip screw, AKA dynamic hip screw, DHS). Despite these interventions, the need for reoperation remains high (10.0-48.8%) and largely unchanged over the past 30 years. Femoral neck fracture is associated with substantial morbidity, mortality, and costs. METHODS: In this study, our group designed a plate that combines the strength of both CCS and sliding hip screw, through providing three dynamic screws at a fixed angle with a side-plate, namely the slide compression anatomic place-femoral neck (SCAP-FN)...

Cochlear implant in children. In a newborn, sensitive auditory stimulations allow the progressive central auditory development. In a congenital severe or profound deaf child, a cochlear implantation can be considered if auditory thresholds are too low to provide an efficient auditory stimulation with hearing aids. This device includes an external processor, which receives and analyses surrounding sounds, and send them to the internal part surgically implanted. The electrode array placed in the cochlea stimulates auditory pathways...

BACKGROUND: Increasing prevalence of metastatic disease has been accompanied by increasing rates of surgical intervention. Current tools have poor to fair predictive performance for intermediate (90-d) and long-term (1-yr) mortality. OBJECTIVE: To develop predictive algorithms for spinal metastatic disease at these time points and to provide patient-specific explanations of the predictions generated by these algorithms. METHODS: Retrospective review was conducted at 2 large academic medical centers to identify patients undergoing initial operative management for spinal metastatic disease between January 2000 and December 2016...

Petrous internal carotid artery (ICA) aneurysms are rare, complicated lesions to treat. The management paradigms include observation, endovascular exclusion, or surgical trapping with or without revascularization. The case described in this video involved a 67-yr-old woman with a known history of chronic lymphocytic leukemia, who presented after a mechanical ground-level fall. Clinically, she had a nasal deformity and resolving epistaxis consistent with mild facial trauma. Computed tomography (CT) revealed a comminuted nasal bone fracture and an incidental 3-cm right petrous ICA aneurysm...

BACKGROUND: In Parkinson's disease, the emergence of motor dysfunction is thought to be related to an imbalance between "antikinetic" and "prokinetic" patterns of oscillatory activity in the motor network. Invasive recordings from the basal ganglia and cortex in surgical patients have suggested that levodopa and therapeutic deep brain stimulation can suppress antikinetic beta band (13-30 Hz) rhythms while promoting prokinetic gamma band (60-90 Hz) rhythms. Surgical ablation of the globus pallidus internus is one of the oldest effective therapies for Parkinson's disease and produces remarkably immediate relief of rigidity and bradykinesia, but its effects on oscillatory activity in the motor network have not been studied...

BACKGROUND: The presence of tumor-infiltrating lymphocytes (TILs) is a prognostic factor for breast cancer. However, because of tumor tissue heterogeneity, an accurate and simple evaluation method is needed. We determined if preoperative characteristic ultrasonography (US) image findings are predictive of lymphocyte-predominant breast cancer (LPBC). METHODS: We evaluated 191 patients with invasive breast cancer treated by curative surgery between January 2014 and December 2017...

Focal cortical dysplasia (FCD) and mild malformation of cortical development (mMCD) are frequent histopathologic diagnoses in patients who undergo surgery for refractory epilepsy. Literature concerning surgical outcome in patients with mMCD, as well as its contrast with FCD, has been scarce. We studied 88 patients with a histopathologic diagnosis of isolated FCD (n = 57) or mMCD (n = 31), revised according to the latest International League Against Epilepsy (ILAE) guidelines, who underwent resective or disconnective surgery...
