Nicotine is harmful to many bodily systems; however, the effects of nicotine on intra-substance tendon healing remain largely unexplored. The purpose this study was examine functional, structural, and biomechanical Achilles tendons in rats after an acute full-thickness injury. Sixty Sprague-Dawley were enrolled study. Half exposed 0.9% saline half 61 ng/mL for 3 months via subcutaneous osmotic pumps. At months, all underwent blunt full thickness transection left immobilized one week...

Aseptic loosening, polyethylene wear, and mechanical failure have limited the use of total elbow arthroplasty (TEA) in physically demanding patients. Newer implant designs been introduced to improve performance. The purpose this study was report results obtained after implantation Nexel TEA.Over a 3-year period, 2 surgeons implanted 35 consecutive primary TEAs. average patient age 65 years, standard TEA indications were utilized. Elbows evaluated for pain, motion, Mayo Elbow Performance...

Fireworks may result in a wide spectrum of injury to the upper extremity ranging from mild burns amputation. In this cross-sectional study, we describe epidemiology upper-extremity injuries United States associated with fireworks using Consumer Product Safety Commission's National Electronic Injury Surveillance System (NEISS).The NEISS database was queried between 2011 and 2017 for all (from shoulder fingertip) fireworks. There were 806 unique cases, yielding total weighted estimate 31,430...

Traditionally, the reconstruction of severe distal humeral bone loss at time revision total elbow arthroplasty (TEA) has used allograft-prosthetic composites (APCs) stabilized with cerclage wires or cables. We have migrated to plate fixation when TEA using a APC is performed. This study shows outcomes patients treated during TEA.Between 2009 and 2019, 41 APCs allograft native humerus were performed in setting TEA. There 12 male (29%) 29 female (71%), mean age 63 years (range, 87 years). The...

The American Society for Surgery of the Hand (ASSH) was established in 1946. Since then, important advances have been made diagnosis and treatment conditions affecting upper extremity. However, there has little documentation regarding how largest oldest society dedicated to hand surgery evolved over time. Furthermore, an understanding history ASSH specialty should be emphasized resident fellow education. authors aim provide a historical overview through speeches past presidents that sheds...

We report a case of 29-year-old woman who sustained left lateral sternoclavicular joint (SCJ) dislocation. Imaging demonstrated 30-mm gap between the sternum and medial clavicle. Given well-preserved shoulder range motion well-controlled pain, she was ultimately treated nonoperatively. SCJ dislocations are rare injuries, comprising 1% all traumatic dislocations. They typically classified into anterior posterior A direct dislocation is considered to be lesser-known type. This presented...

Upper extremity abscesses frequently present to the acute care setting with inconclusive physical examination and imaging findings. We sought investigate diagnostic accuracy of inflammatory markers including white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP). A retrospective cohort study was performed identify subjects ≥18 years treated surgical debridement upper at our institution between January 2012 December 2015. In this study, 188 patients were...

Primary hemiarthroplasty is gaining popularity for the treatment of unstable intertrochanteric fractures in geriatric patients with severe osteoporosis. This study evaluated early clinical and radiographic outcomes by using a bone-conserving revision stem osteoporotic population.A retrospective involving 31 was conducted. The were aged 82.1 years on average. All underwent primary bone-conserving, fully porous-coated stem. operative time, intraoperative blood loss, length hospitalization,...

Background: This study aimed to describe the epidemiology of pediatric upper extremity injury secondary nonballistic firearms in United States. Methods: The National Electronic Injury Surveillance Survey (NEISS) database was queried between 2000 and 2017 for injuries from patients aged ≤18 years. In total, 1502 unique cases were identified. Using input parameters intrinsic NEISS database, national weighted estimates derived using Stata/IC 15.1 statistical software (StataCorp LLC, College...

Objective: The surgical management of petroclival meningioma remains challenging, due to the difficulty accessing region and vital structures adjacent origin these tumors. developments a multitude approaches as well innovations in neuroimaging stereotactic radiation have proved powerful options for multimodality challenging Study Design, Material, Methods: We review major series patients, comparing classification, imaging techniques, operative technique, outcome, use adjuvant radiotherapy...

Heterotopic ossification typically occurs after a systemic inflammatory process and may lead to limitations in range of motion, depending on its severity. We present the case 52-year-old male who developed left shoulder pain stiffness prolonged hospitalization for treatment COVID-19. Subsequent imaging revealed formation bone extra-osseous sites surrounding his joint, which led auto-fusion glenohumeral joint. He underwent heterotopic excision reverse total arthroplasty order restore...
