This study examined the incidence and risk factors associated with lateral helical blade migration and trochanteric pain with the trochanteric fixation nail. A retrospective review was performed of 141 cases of pertrochanteric femur fracture treated with a trochanteric fixation nail at a level I trauma center over a period of 42 months. Exclusion criteria included follow-up of less than 60 days, preexisting osteonecrosis of the femoral head, and prophylactic trochanteric fixation nail treatment. Patient demographics, operative findings, and radiographic findings were recorded...

BACKGROUND: Infected non-unions of the supracondylar region of the femur are uncommon. Even though hardware removal is a common procedure, it may lead to complications, including neurovascular injury, refracture, worsening pain or recurrence of deformity. CASE PRESENTATION: We report on a male who developed subcutaneous emphysema of the leg after hardware removal and bone allografting for an infected non-union of the distal femur. He was managed by debridement of the surgical wound, antibiotic therapy, multiple fasciotomies, and application of a VAC (vacuum-assisted closure) system...

BACKGROUND/PURPOSE: Radial head replacement is frequently used in treatment of radial head fractures or sequela. Impossibility to restore a correct anatomy, acute elbow traumatic instability and failure of osteosynthesis hardware are the most common indications. The authors describe their case studies and results on the implantation of various radial head prostheses. MATERIALS: Between June 2005 and June 2016, 28 radial head prostheses were implanted in the same number of patients with an average follow-up of 49 months (6-104)...

INTRODUCTION: For any orthopaedic surgeon working with trauma; ankle fractures are one of the most common injuries treated. The treatment of ankle fractures can be conservative, using external fixation, but more commonly the fractures are treated with open reduction and internal fixation. Residual pain and discomfort are common in patients after surgical treatment of fractures of the ankle. Sometimes it is difficult to determine whether the pain or discomfort is due to the implants left in situ or the primary injury itself...

We report a new 'pure-shift' method, termed 'SHARPER' (Sensitive, Homogeneous And Resolved PEaks in Real time) de-signed for the analysis of reactions and equilibria by NMR. By focusing on a single selected signal, SHARPER removes all heteronuclear couplings of a selected nucleus without the need to pulse on X channels, thus overcoming hardware limitations of conventional spectrometers. A more versatile decoupling scheme, termed 'sel-SHARPER', removes all heteronuclear and homonuclear couplings of the selected signal...

Until today the role of spinal instrumentation in the presence of a wound infection has been widely discussed and recently many authors leave the hardware in place with appropriate antibiotic therapy. This is a case of a 65-year-old woman suffering from degenerative scoliosis and osteoporotic multiple vertebral collapses treated with posterior dorsolumbar stabilisation with screws and rods. Four months later, skin necrosis and infection appeared in the cranial wound with exposure of the rods. A surgical procedure of debridement of the infected tissue and package with a myocutaneous trapezius muscle flap was performed...

BACKGROUND: There remains a paucity of studies examining the conversion of failed hemiarthroplasty (HA) to reverse total shoulder arthroplasty (RTSA). Therefore, the purpose of this study was to examine a large series of revision HA to RTSA. METHODS: A population of 157 patients who underwent conversion of a failed HA to a revision RTSA from 2006 through 2014 were included. The mean follow-up was 49 months (range, 24-121 months). The indications for revision surgery included instability with rotator cuff insufficiency (n = 127) and glenoid wear (n = 30); instability and glenoid wear were associated in 38 cases...

Eating habits in cattle are less discriminant than other ruminants, and they more often accidentally ingest strange objects while feeding. Penetrating foreign bodies may cause mild to severe peritonitis, penetrate the diaphragm to cause pleuritis or pericarditis, or cause localized abscesses in the thorax or abdomen. Because these objects are most often metal, a common term for this problem is hardware disease. An accurate history and thorough physical examination often yields a diagnosis; however, ancillary diagnostics can enhance accuracy and disease magnitude before exploratory surgery...

AIM: To enhance the clinical utility of electrogastrography (EGG), which has been recorded since 1922, but is clinically unutilized. METHODS: An innovative method to salvage the promise of EGG is proposed by introducing a preliminary procedure, while maintaining the electrodes, standardized equipment, and signal processing utilized in the well-established EGG testing of today. The proposed enhanced EGG (EEGG) protocol involves swallowing an ingestible capsule containing miniature electronic oscillator embedded in an expandable, self-disintegratable, biocompatible pseudobesoar residing in the stomach for the duration of the test...

INTRODUCTION: Deep Brain Stimulation (DBS) is an effective treatment extended broadly to many neurological and psychiatric disorders. Nevertheless, complications may arise during DBS procedures or following implantation due to implanted hardware. This may result in both minor and major adverse events that may necessitate hardware removal and/or compromise maximal therapeutic benefit for the patient. OBJECTIVES AND METHODS: To identify relevant literature on hardware-related complications from DBS procedures by performing a systematic review, and propose how to identify at-risk group and possible preventive approaches...

Deep neural networks (NNs) are the state-of-the-art models for understanding the content of images and videos. However, implementing deep NNs in embedded systems is a challenging task, e.g., a typical deep belief network could exhaust gigabytes of memory and result in bandwidth and computational bottlenecks. To address this challenge, this paper presents an algorithm and hardware codesign for efficient deep neural computation. A hardware-oriented deep learning algorithm, named the deep adaptive network, is proposed to explore the sparsity of neural connections...

INTRODUCTION: Surgical site infection is a potential complication of spinal cord stimulator (SCS) implantation. Current understanding of the epidemiology, diagnosis, and treatment of these infections is based largely on small clinical studies, many of which are outdated. Evidence-based guidelines for management of SCS-related infections thus rely instead on expert opinion, case reports, and case series. In this study, we aim to provide a large scale retrospective study of infection management techniques specifically for SCS implantation...

BACKGROUND: Patellar tendon chronic ruptures are more debated to manage that acute injuries as the patella tends to retract proximally (after 2 weeks), and surrounding soft tissues may make the repair more complicate. PURPOSE: We propose a novel technique in which the patellar tendon is reconstructed using ipsilateral hamstring tendons. This surgical procedure implies to drill a single tunnel through the patella and another through the tibia to reduce the risk of bony breakage...

Artifact caused by irregular respiration is a major source of error in 4D-CT imaging. We propose a new prospective 4D-CT to mitigate this source of error without new hardware, software or off-line data-processing on the GE CT scanner. We utilize the cine CT scan in the design of the new prospective 4D-CT. The cine CT scan at each position can be stopped by the operator when an irregular respiration occurs, and resumed when the respiration becomes regular. This process can be repeated at one or multiple scan positions...

PURPOSE: Operative fixation of displaced patella fractures is considered to be standard of care. However, patients with inferior pole patella fractures have limited options in terms of fixation. This video demonstrates the repair of an inferior pole patella fracture using nonabsorbable suture fixation. METHODS: Suture repair of patella fractures is a clinically acceptable technique, yielding similar functional results to patella fractures treated with K-wires or cannulated screws while reducing the rates of removal of hardware after fixation...

Multiplexing, labeling for multiple immunostains in the very same cell or tissue section in situ, has raised considerable interest. The methods proposed include the use of labeled primary antibodies, spectral separation of fluorochromes, bleaching of the fluorophores or chromogens, blocking of previous antibody layers, all in various combinations. The major obstacles to the diffusion of this technique are high costs in custom antibodies and instruments, low throughput, and scarcity of specialized skills or facilities...

BACKGROUND: Open reduction and internal fixation (ORIF) of the clavicle is a common procedure that has been shown to have improved outcomes over nonoperative treatment. Several incisions can be used to approach clavicle fractures, the decision of which is variable among surgeons. PURPOSE: To compare patient satisfaction and subjective outcomes between patients with a longitudinal incision versus those with a necklace incision for the treatment of diaphyseal clavicle fractures...
