broken necks

BACKGROUND: Femoral neck fractures need to be treated in their early stages with accurate reduction and stable fixation to reduce complications. The authors compared the early radiologic outcomes of femoral neck fractures treated with the recently introduced Femoral Neck System (FNS, Depuy-Synthes) with conventional cannulated screws (CS) in a multicenter design. Furthermore, the factors associated with early failure after FNS were analyzed. METHODS: The FNS group included 40 patients treated between June 2019 and January 2020, and the CS group included 65 patients treated between January 2015 and May 2019...

Tracheostomy is commonly performed in patients to secure the airway. There are known early and late complications related to tracheostomy. Few case reports have described the rupture of the stem of the tracheostomy tube and its migration into the tracheobronchial tree. Here we describe a pediatric case with a broken stem of the tracheostomy tube in the trachea, acting as a foreign body and causing mild respiratory distress. The patient was successfully managed with neck exploration under general anesthesia using a supraglottic airway device in low-resource settings...

Snakebite is an acute life-threatening medical emergency and is included among the neglected tropical diseases in India. The incidence of snakebite mortality is particularly high in Southeast Asia and India has the highest number of cases of snakebites with a mortality of 35,000 to 50,000 cases per year according to the World Health Organization (WHO) direct estimation. There are three families of venomous snakes in Southeast Asia which mainly include Elapidae, Viperidae, and Colubridae. Snakebite victims show varied clinical presentations ranging from local signs to systemic signs of envenomation...

Retained needles are frequently observed in intravenous drug users. However, an incidental discovery of multiple needles at the neck seldom occurs. These foreign bodies remain either asymptomatic or cause local and central complications that can be fatal. We report the case of a 43-year-old male having a medical record of human immunodeficiency virus and hepatitis C who presented to our department with a 3-day history of a febrile lateral neck swelling. He reported a history of repetitive intravenous drug use and previous abscesses that were surgically drained...

Injuries in the neck region are rarely observed in forensic practice, especially of accidental origin. Primarily, such cases are associated with homicide or suicide. The neck region comprises different and vital anatomical structures, and even minor trauma could be lethal. In the absence of witnesses to the accident, each finding is of utmost importance, from the death/crime scene investigation - bloodstain patterns and trace evidence - to careful examination of the deceased body. The forensic pathologist has the challenging task of analyzing all the findings to make a statement concerning the cause and manner of death and, if there is something suspicious about the current case, to inform the relevant authorities...

The Harvard Art Museums' collection includes six Egyptian funerary portraits of the Roman period. These portraits are all that remains of the funerary equipment of individuals whose bodies were carefully prepared for burial and the afterlife. One example, depicting a man, is particularly complicated, broken into multiple fragments which have been glued down onto a board. The in-depth study of the portrait used a combination of non-invasive techniques, including X-radiography, infrared-, ultraviolet- and visible-induced luminescence imaging, and X-ray fluorescence spectroscopy to identify and locate particular pigments, binders and other artist materials, without needing to take a sample...

SETTING: The US Food and Drug Administration (FDA) 2011 to 2021 Manufacturer and User Facility Device Experience (MAUDE) database. METHODS: The MAUDE database was queried for reports of "microdebrider," with adverse events selected that pertained to usage in head and neck surgeries from January 1, 2011 to December 31, 2021...

Needle fracture during dental local anesthetic injections is a rare but significant, potentially serious complication. Various approaches for the location and removal of broken needles have been described; however, there are several difficulties and concerns related to the potential complications and critical anatomic challenges peculiar to the head and neck region. In this case, we describe the diagnostic approaches utilized in locating a broken needle that migrated in the pterygomandibular space following gag reflex, and sudden head movement of a middle-aged male patient...

BACKGROUND: Locking a compression plate is a more favorable surgical technique than intramedullary nailing in the treatment of distal femur fractures. This study analyzed the risk factors of proximal screw breakage retrospectively, which was confirmed in the patients with plate removal after bony union. METHODS: A total of 140 patients who were fixed by MIPO using ZPLP from 2009 to 2019 were identified. A total of 42 patients met the inclusion criteria and were included...

PURPOSE/OBJECTIVE(S): Head and neck (H&N) radiation (RT) is characterized by significant acute toxicity, but long-term quality of life (QoL) following H&N RT is not well defined. This study sought to prospectively characterize, by subsite, long-term QoL in patients who underwent H&N RT using the Vanderbilt Head and Neck Symptom Survey (VHNSS) version 2.0. MATERIALS/METHODS: In patients treated with H&N RT between 2010 and 2021, the VHNSS was prospectively collected prior to beginning RT and at follow-up visits after completion of RT...

OBJECTIVE: Many facial plastic surgery procedures can be performed in an office-based setting, ranging from simple chemical peels to reconstructive surgeries to assist with scar revision. The aim of this review is to summarize the current state of facial plastics in-office surgical procedures, including scar revision, dermabrasion, lasers, and chemical peels. METHODS: A literature review was conducted with the PubMed search engine with the following keywords: facial plastics, scar revision, dermabrasion, lasers, chemical peels, face, office, and outpatient...

The cementless Corail stem is one of the most frequently implanted stems and has undergone several design changes. Currently in use is the third generation, named Corail AMT. Until now, only one third-generation Corail stem neck fracture has been described in 2020. In our paper, we present an almost identical complication with an additional analysis of the fracture using a scanning electron microscope. The revision surgery consisted of changing the broken implant with a Corail revision stem, along with replacing the polyethylene liner and the femoral head with new one, after which the patient achieved a full recovery...

This study presents a comparative analysis of the tensile properties of 3D-printed polymer specimens with different standard geometry shapes. The objective is to assess the influence of printing orientation and geometry on the mechanical performance. Rectangular-shaped ASTM D3039 specimens with angles of 0°, 15°, and 90° are compared to various tensile test specimens based on ASTM and ISO standards. All specimens are fabricated using polyethylene terephthalate glycol (PETG) material through fused deposition modeling (FDM)...

CASE: The Synthes Femoral Neck System (FNS) is a relatively new device available to the market in 2019 designed to reduce complication and revision rates after femoral neck fracture stabilization. We present a 77-year-old man with Parkinson disease and avascular necrosis after femoral neck fracture initially managed with the FNS. Subsequent challenges in device removal occurred because of its propensity for bony integration, plate and locking screw welding, and screw head recess destruction...

Objective: Three modeling methods were used to establish a mouse primary liver cancer model, and compared them to find a more optimal modeling method. Methods: Forty 15-day-old C3H/HeN male mice were randomly divided into groups I-IV, 10 mice in each group. Group Ⅰ were not treated; Group Ⅱ were intraperitoneally injected with 25 mg/kg diethylnitrosamine (DEN) once; Group Ⅲ were intraperitoneally injected with 100 mg/kg DEN once; Group Ⅳ were intraperitoneally injected with 25 mg/kg DEN once and followed by another intraperitoneal injection of 100 mg/kg DEN at 42 days of age...

Broken eggs can be harmful to human health but are also unfavorable for transportation and production. This study proposes a video-based detection model for the real-time detection of broken eggs regarding unwashed eggs in dynamic scenes. A system capable of the continuous rotation and translation of eggs was designed to display the entire surface of an egg. We added CA into the backbone network, fusing BiFPN and GSConv with the neck to improve YOLOv5. The improved YOLOV5 model uses intact and broken eggs for training...

Skin cancer defects of the head and neck region can vary greatly in their complexity. Reconstructive surgeons are tasked with maintaining or restoring function as well as providing an excellent aesthetic outcome. This article provides an overview of reconstructive options following skin cancer resection broken down by different aesthetic regions and subunits. Although not meant to serve as an all-encompassing source, it provides common indications for using different sections of the reconstructive ladder based on location of defects, tissues involved, and patient factors...

The ingestion of foreign body is a very common occurrence in pediatric age group. The retrieval is an emergency procedure performed mostly by the Otolaryngologist and Gastroenterologist. We present a case of coin ingestion who reported to a tertiary care center. It was retained in the lower part of esophagus as confirmed by imaging. Subsequently during the rigid esophagoscopy it was found missing from distal esophagus. A 9 year old female child presented with accidental ingestion of coin. The imaging done immediately prior to intervention confirmed position of coin in distal esophagus...

Subclavian artery aneurysms are infrequently observed in clinical settings, and are divided into intrathoracic and extra-thoracic segments. Atherosclerosis, cystic necrosis of the tunica media, trauma, or infections are more common. Blunt trauma or piercing is more frequently the cause of pseudoaneurysms, and broken bones following surgery should be evaluated. A 78-year-old woman attended the vascular clinic with a closed mid-clavicular fracture due to plant trauma before 2 months. Physical examination revealed a well-healed wound and no palpable pain, but a massive pulsating mass with normal overlying skin in the superior side of the clavicle...

Impurity detection is an important link in the chain of food processing. Taking walnut kernels as an example, it is difficult to accurately detect impurities mixed in walnut kernels before the packaging process. In order to accurately identify the small impurities mixed in walnut kernels, this paper established an improved impurities detection model based on the original YOLOv5 network model. Initially, a small target detection layer was added in the neck part, to improve the detection ability for small impurities, such as broken shells...
