Role of antibiotics in open fractures of the finger The role of antibiotics was investigated prospectively in 91 open fractures of the finger. Antibiotics were administered to alternate patients with open phalangeal fractures. Only finger fractures distal to the metacarpophalangeal joint were included. Both groups were treated with aggressive surgical irrigation and debridement. In four patients in each group clinical signs of infection eventually developed; osteomyelitis did not develop in any patients, and no secondary surgical procedures were required in either group. This data indicates that vigorous irrigation and debridement is adequate primary treatment for open phalangeal fractures in fingers with intact digital arteries.

Read Full License Page 1/16 Abstract Background: In light of the new circumstances caused by the current COVID-19 pandemic, an enhanced knowledge of hand injury patterns may help with prevention in factories as well as the management of related medical conditions. Methods: A sample of 95 patients were admitted to an orthopedics department with an emergent hand injury within half a year of the COVID-19 outbreak. Data were collected between January 23rd, 2020 and July 23rd, 2020. Information was collected regarding demographics, type of injury, location, side of lesions, mechanism of injuries, place where the injuries occurred, surgical management, and outcomes. Results: The number of total emergency visits due to hand injury during the COVID-19 outbreak decreased 37% when compared to the same period in the previous year. At the same time, work resumption injuries increased 40%. In comparison to the corresponding period in the previous year, most injured patients during the COVID-19 outbreak were women (60%) with a mean age of 56.7, while during the work resumption stage, most were men (82.4%) with a mean age of 44.8.

Department of Orthopaedics and Rehabilitation, Penn State College of Medicine, Hershey, USA 2. Department of Orthopaedic Surgery, University of Minnesota Twin Cities, Minneapolis, USA 3. Department of Orthopaedics and Rehabilitation, Penn State Health Milton S. Hershey Medical Center, Hershey, USA Corresponding author: Tommy Pan, [email protected] Abstract Purpose: Supracondylar humerus (SCH) fractures are the most common elbow fracture in children; however, they rarely occur as open injuries. Open fractures are associated with higher rates of infection, neurovascular injury, compartment syndrome, and nonunion. The purpose of this study was to evaluate the treatment and outcomes of open SCH fractures in children. Methods: Between 2008 and 2015, four children (1%) had open injuries among 420 treated for SCH fractures at a single center. The mean patient age was six years (range, four to eight years). Two patients had Gustilo- Anderson grade 1 open fractures and two had grade 2 fractures. Tetanus immunization was up-to-date in all. First dose of intravenous antibiotics was given on average 3hr 7min after onset of injury (range, 1hr 38min to 8hr 15min). Time from injury to irrigation and debridement (I&D) and closed reduction and percutaneous pinning (CRPP) was on average 8hr 16min (range, 4hr 19min to 13hr 15min). All patients received 24-hour intravenous antibiotics. Pins were removed at four weeks and bony union occurred by six weeks. Results: After an average follow-up period of 12 months (range, 6 to 22 months), there were no infections, neurovascular deficits, compartment syndromes, cubitus varus deformities, or range of motion losses.

Yancosek 2010 ABSTRACT OF DISSERTATION INJURY-INDUCED HAND DOMINANCE TRANSFER Hand dominance is the preferential use of one hand over the other for motor tasks. 90% of people are right-hand dominant, and the majority of injuries (acute and cumulative trauma) occur to the dominant limb, creating a double-impact injury whereby a person is left in a functional state of single-handedness and must rely on the less- dexterous, non-dominant hand. When loss of dominant hand function is permanent, a forced shift of dominance is termed injury-induced hand dominance transfer (I-IHDT).

  • Open Fracture Management
    Clinical Practice Management Guidelines Open Fracture Management I. Classification of Open Fractures (Gustilo Classification) Type I: Open fracture with a skin wound <1 cm in length and clean. Type II: Open fracture with a laceration >1 cm in length without extensive soft tissue damage, flaps, or avulsions. Type III: Open segmental fracture with >10 cm wound with extensive soft tissue injury or a traumatic amputation. Special categories in Type III include gunshot fractures and open fractures caused by farm injuries. IIIA Adequate soft tissue coverage. IIIB Significant soft tissue loss with exposed bone that requires soft tissue transfer to achieve coverage. IIIC Associated vascular injury that requires repair for limb preservation. II. Antibiotics for Open Fractures A. Statement of the Problem An open fracture, in which the fracture fragments communicate with the environment through a break in the skin, increases the risk of infection and soft tissue complications. It is accepted that the risk of infection and incidence of limb loss correlate with the Gustilo type. The prompt administration of appropriate antibiotics is believed to reduce these complications. B. Recommendations Systemic antibiotic coverage directed at gram-positive organisms should be initiated as soon as possible after injury, within one hour of arrival from the scene, prior to transfer from outlying hospital. Cefazolin 1-2 gm every 8 hours. Clindamycin 900 mg every 8 hours (Pcn allergy). Additional gram-negative coverage should be added for type III fractures. Gentamicin 6 mg/kg daily for patients with normal renal function. Obese patients require dosing based on Dosing Weight. Piperacillin/Tazabactam may be used in place of Cefazolin/Gentamicin in the face of rhabomyolyis and in impaired renal function.

(Orthopaedics), Assistant Professor, Dept. of orthopaedics, Government Medical College, Haldwani, Uttarakhand, India. Abstract Gas gangrene is a sinister infection that often results in serious limb morbidity and dismemberment of the extremity is the sole option in severe cases. The prevention and early, meticulous debridement may help modify the course of disease and prevent the condition in some instances. The knowledge of factors associated with increased risk is important to mitigate the problem of inappropriate assessment of the infection. The early decision of amputation, if salvage seems unlikely, proves critical in saving life of the patient. The associated condition of diabetes potentiates the presence of infection and compounds the problem. The occurrence of gas gangrene in the setting of fractures is limited to few reports or small series and as the incidence of the condition is on decline, its potential to occur in high risk group should not be taken lightly. We, hereby, present a case of severe gas gangrene of leg following fractures of both bones with small open wound that was neglected and led to fulminant infection with an untoward outcome.

  • Searching for Information on Occupational Accidents
    SEARCHING FOR INFORMATION ON OCCUPATIONAL ACCIDENTS DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Shih-Kwang Chen, M.S. ***** The Ohio State University 2008 Dissertation Committee: Approved by Professor Philip J. Smith, Adviser Professor Jerald R. Brevick Adviser Professor Steven A. Lavender Industrial and Systems Engineering Graduate Program Copyright by Shih-Kwang Chen 2008 ABSTRACT Effective retrieval of the most relevant documents on the topic of interest from the Internet is difficult due to the large amount of information in all types of formats. Studies have been conducted on ways to improve information retrieval (IR). One approach to improve searches in large collections, such as the Web, is to take advantage of semantic representations in pre-existing relational databases that have been developed for explicit purposes besides supporting Internet searches in general. In an effort to enhance IR on the Internet, a prototype of a topic-oriented search agent, SAOA-1, was developed to use embedded semantics and domain-specific knowledge extracted from such a database. Activated when a set of retrieved keywords appears related to the topic of “occupational accidents”, SAOA-1 constructs an alternative search query and pruned lists of suggested refinements by applying the search engine knowledge and the domain- specific knowledge and semantics extracted from a relational database. Information seekers could then use the alternative search query or refine it further with a modified search query developed by SAOA-1 based on its semantic representation of the topic of occupational accidents to complete context-sensitive pruning of the semantic neighborhood.
