INTRODUCTION: The optimal treatment of humeral shaft fractures continues to be debated. In the current investigation, we sought to determine the clinical and radiographic outcomes following the plate fixation of humeral shaft fractures utilizing the triceps-sparing posterior approach. MATERIALS AND METHODS: A retrospective review identified a consecutive series of 66 humeral shaft fractures (OTA 12-A, 12-B, or 12-C) treated with dual plate fixation via a posterior, triceps-sparing approach between 2005 and 2014 by a single surgeon...

BACKGROUND: Evolving wrist arthroscopy requires creating new portals, and creating portals reciprocally leads to increased indications for arthroscopic wrist procedures. To facilitate access to the lunate bone and fossa for new arthroscopic procedures, a new portal was used. This is a cadaveric study of this portal. OBJECTIVES: In this cadaveric study, we evaluated a portal in wrist arthroscopy for procedures involving the lunate bone and lunate fossa. MATERIALS AND METHODS: Seventeen wrists from 10 fresh cadavers were included in this study...

BACKGROUND: Neurologic lesions are relatively common after total shoulder arthroplasty. These injuries are mostly due to traction. We aimed to identify the arm manipulations and steps during reverse total shoulder arthroplasty (RTSA) that affect nerve stress. METHODS: Stress was measured in 10 shoulders of 5 cadavers by use of a tensiometer on each nerve from the brachial plexus, with shoulders in different arm positions and during different surgical steps of RTSA...

Spinal cord and peripheral nerve injuries require the regeneration of nerve fibers across the lesion site for successful recovery. Providing guidance cues and soluble factors to promote neurite outgrowth and cell survival can enhance repair. The extracellular matrix (ECM) plays a key role in tissue repair by controlling cell adhesion, motility, and growth. In this study, we explored the ability of a mesenchymal ECM to support neurite outgrowth from neurons in the superior cervical ganglia (SCG). Length and morphology of neurites extended on a decellularized fibroblast ECM were compared to those on substrates coated with laminin, a major ECM protein in neural tissue, or fibronectin, the main component of a mesenchymal ECM...

Krabbe's disease is a rare autosomal recessive lysosomal disorder resulting from deficiency of β-galactocerebrosidase that affects primarily cerebral white matter and peripheral nerves. Conventional magnetic resonance imaging (MRI) is sensitive to changes in white matter myelination, but its assessment is based purely on qualitative, visual inspection, and it is subject to interobserver variability and open to reader bias. Diffusion tensor imaging (DTI) is an advanced MRI technique that provides quantitative information about the microscopic structural organization of the white matter and changes in cell density and myelination, and it is a suitable MRI tool for studying Krabbe's disease...

BACKGROUND: Cardiovascular procedures are common and are trending toward endovascular interventions. With this increase in endovascular procedures, there is also increasing awareness of upper extremity morbidity resulting from treatment. METHODS: Articles indexed within PubMed between the years 1975 and 2015 that discussed such complications were reviewed. RESULTS: Percutaneous radial artery access can lead to nerve ischemia, especially in the setting of an incomplete arterial arch, whereas radial artery harvesting for bypass surgery more commonly causes frank tissue ischemia and radial neuropathy...

INTRODUCTION: Carpal tunnel steroid injections (CTIs) have the potential risk of damaging underlying critical structures, including the median nerve (MN), radial artery (RA), and ulnar neurovascular bundle (UB). The purpose of this study was to analyze the safety of a volar radial (VR) and volar ulnar (VU) CTI, using standardized anatomical "safe zones." MATERIALS AND METHODS: This study was performed on 87 cadaveric arms using a percentage of the total wrist width as a guide for placement of a VR (30 and 33% of total wrist width) and VU (60 and 66% of total wrist width) injection...

PURPOSE: Distal-third diaphyseal fractures of the humerus are often hard to treat due to location and pattern of the fractures, radial nerve injury, and quality of bone and age of patients. The aim of this retrospective study is to propose the best approach and the best surgical technique according to the pattern of extra-articular fracture of the distal humerus. METHODS: We have treated 37 fractures of the distal humerus between January 2010 and July 2015 classified according to the AO classification...

Paediatric Monteggia-type injuries are complicated by treatment failure and posterior interosseous nerve palsy, without reliable predictive indicators. Outcome is considered to be good, with little patient-reported evidence. We propose novel radiographic parameters. A total of 33 Monteggia-type injuries were analysed. Posterior interosseous nerve palsy was strongly predicted by the Radial Head Displacement Index. The presence of two or more of three novel instability markers was associated strongly with treatment failure...

BACKGROUND: The anatomy of the lateral antebrachial cutaneous nerve (LABCN) in relation to volar approaches to the distal radius is not well visited. With the increasing popularity of distal radius fracture fixation with volar locking plates, it is prudent to study the innervation pattern of the LABCN to minimize the risk of nerve injury. METHODS: Ten cadaveric distal radial forearms were dissected to study the relationship between the LABCN, flexor carpi radialis (FCR), superficial branch of radial nerve (SBRN), and scaphoid tubercle (ST)...
