OBJECTIVE: Despite gender-affirming laryngological services (GALS; eg, voice therapy or surgery) being available nationwide, there is a discrepancy between the number of transgender and gender diverse (TGD) people with vocal incongruence and those who pursue services. Primary care is an important setting for accessing gender-affirming care, including learning about GALS. The purpose of this study was to understand the relationship between access to primary care and utilization of GALS...

Osteosarcoma is a highly invasive primary bone tumor that predominantly occurs in childhood and adolescence. The Stryker Growing Prosthesis provides a means of reconstructing large bone defects resulting from bone resection in skeletally immature patients. This device can be expanded as the patient grows. The possible length of extension depends on the length of the prosthesis. Because further expansion was not possible, by turning the adjustable part of the extension back to zero and adding a new permanent extension allow the prosthesis to be further adjusted as growth ensues...

OBJECTIVE: Lumbar interbody fusion (LIF) is a common surgical procedure, but postoperative complications, such as osteolytic vertebral endplate cysts, can adversely affect patient outcomes. This study aims to investigate whether Tritanium cages (Stryker, Mahwah, NJ) are effective in preventing osteolytic vertebral endplate cysts after LIF. METHODS: Clinical data from 8 years (2013-2020) of LIF procedures at our hospital were analyzed. Computed tomography was employed to assess the formation of osteolytic vertebral endplate cysts 6 months post-surgery...

INTRODUCTION: Indocyanine green (ICG) angiography is the 'real-time intraoperative imaging' technique used to reduce the chances of hypoparathyroidism in post-thyroidectomy patients. In our study, the authors predicted the risk of early post-thyroidectomy hypocalcemia by intraoperative evaluation of parathyroid gland perfusion by ICG angiography. MATERIALS AND METHODS: In patients who underwent total thyroidectomy, ICG angiography was done using the SPY PHI imaging system (Stryker)...

INTRODUCTION: Total ankle arthroplasty (TAR) procedures have become more reliable and incidence is increasing. A growing number of postoperative complications can be expected and should be correctly addressed. PRESENTATION OF CASE: A 43-year-old woman suffering from severe ankle osteoarthritis underwent TAR (Stryker's Infinity with Prophecy alignment guides, uncemented tibial component and cemented talus component). After a fall, one month after the surgery, she presented with a fracture of the medial malleolus and an anterior periprosthetic fracture of the tibia, with anterior dislocation of the tibial prosthetic component...

Intraoperative vertical coracoid graft fractures during the Latarjet procedure are well-described complications, which typically have a poor prognosis or may necessitate further iliac crest bone grafting for stabilization. The vertical split coracoid fractures are reasoned to be caused by excessive tightening of the screws, poor bone quality, especially in females and the smaller dimension of the coracoid graft. In this technical note, we propose an arthroscopic salvage technique for salvaging the fractured coracoid graft and to avoid the need for additional bone graft, thereby reducing morbidity to the patient...

Can Pyrocarbon be used as a functional spacer for the treatment of recalcitrant shoulder infections?
Hugo Barret, Pascal Boileau
BACKGROUND: The most common treatment approach in periprosthetic joint infection (PJI) and chronic shoulder joint infection (SJI) is a two-stage revision involving interval placement of an antibiotic cement spacer or a resection arthroplasty. Knowing that Pyrocarbon has a smooth surface that prevents pathogen adhesion, the question arises whether it could be used as a temporary or permanent functional spacer? PURPOSE: The primary objective of the present study was to assess the rate of infection eradication after temporary or definitive implantation of Pyrocarbon Interposition Shoulder Arthroplasty (PISA) in patients with recalcitrant PJI or SJI...

Cortical inhibitory interneurons (cINs) are born in the ventral forebrain and migrate into the cortex where they make connections with locally produced excitatory glutamatergic neurons. Cortical function critically depends on the number of cINs, which is also key to establishing the appropriate inhibitory/excitatory balance. The final number of cINs is determined during a postnatal period of programmed cell death (PCD) when ~40% of the young cINs are eliminated. Previous work shows that the loss of clustered gamma protocadherins (Pcdhgs), but not of genes in the Pcdha or Pcdhb clusters, dramatically increased BAX-dependent cIN PCD...

Femoral neck trunnion dissociations are rare complications of total hip replacements. This hardware failure is often due to underlying trunnionosis which is important to recognize. We present a case of a patient with dissociation at the femoral head-neck junction of a total hip arthroplasty (THA) with a Stryker Accolade TMZF femoral stem. There was no significant preceding trauma. The complication was visualized on radiography and confirmed during revision arthroplasty.

Left ventricular (LV) unloading has been shown to improve survival for patients requiring veno-arterial extracorporeal membrane oxygenation (VA ECMO) support for cardiogenic shock. A mortality benefit has been shown for ECMO and concomitant placement of a transcatheter unloading LV pump such as an Impella device (colloquially referred to as ECPELLA or ECMELLA) for patients resuscitated with VA ECMO after a short period of cardiac arrest. Despite the described benefit of LV unloading with VA ECMO for cardiopulmonary resuscitation, it remains unclear as to what criteria should be used and what other diagnostic and therapeutic adjuncts may be useful...

The retina and primary visual cortex (V1) both exhibit diverse neural populations sensitive to diverse visual features. Yet it remains unclear how neural populations in each area partition stimulus space to span these features. One possibility is that neural populations are organized into discrete groups of neurons, with each group signaling a particular constellation of features. Alternatively, neurons could be continuously distributed across feature-encoding space. To distinguish these possibilities, we presented a battery of visual stimuli to the mouse retina and V1 while measuring neural responses with multi-electrode arrays...

INTRODUCTION: Humeral-sided complications account for up to 21% of all revision Reverse Total Shoulder Arthroplasty (RTSA) surgeries.1 Stress shielding with large bulky stems can lead to proximal bone resorption per Wolff's law, complicating further surgeries.14,28 Previously published studies suggest that lowering the metaphyseal implant fill ratio can lead to fewer adaptive radiographic changes and decreased bone resorption.25,26,29 Inspired by these studies, cementless primary RTSA implantation technique with humeral matchstick autografts was proposed to augment cementless humeral constructs, foster the use of a smaller size stem, and create primary stability of the humeral implant even in osteoporotic or in-between size medullary canals...

Current hypotheses on the mechanisms underlying the development and plasticity of the ocular dominance system through competitive interactions between pathways serving the two eyes strongly suggest the involvement of neurotrophins and their high affinity receptors. In the cat, infusion of the tyrosine kinase B ligand (trkB), neurotrophin-4/5 (NT-4/5), abolishes ocular dominance plasticity that follows monocular deprivation (Gillespie et al., 2000), while tyrosine kinase A and C ligands (trkA and trkC) do not have this effect...

Treatment of large dysplastic middle cerebral artery (MCA) aneurysms can be challenging.1 2 Catheterization of M2 branches at hyperacute angles often requires an 'around the world' approach/microcatheter reduction, which can be accomplished with rapid pull,3 balloon anchor,4 and stent anchor5 techniques. In this video video 1, Atlas stents (Stryker) are used for double microcatheter reduction along with Y stent assisted coil embolization (Video 1). Steps include (1) catheterization of the more difficult M2 branch with 'around the world' maneuver; (2) reduction/stent deployment; (3) similar catheterization of the second M2 branch; (4) microcatheter reduction/stent deployment; (5) coil embolization (jailed)...

Contour (Stryker, Kalamazoo, MI) is a relatively new endosaccular device for the treatment of intracranial aneurysms.1 2 Its unique cup-like shape permits treatment of most lesions, including wide-necked, irregular, and shallowed-shaped aneurysms. The sizing of the device only requires two parameters: neck size and equatorial plane (width). It must be positioned at the neck of the aneurysm with the device proximal marker in the parent artery. In our experience, dual antiplatelet therapy is usually not required for intrasaccular devices and this is also an advantage of the Contour device...
