photographing injuries in the acute care setting development and evaluation of a standardized protocol for research forensics and clinical practice
Academic Emergency Medicine, 2016Co-Authors: Elizabeth M Bloemen, Tony Rosen, Justina Cline A Schiroo, Sunday Clark, Mary R Mulcare, Michael E Stern, Regina Mysliwiec, Neal E Flomenbaum, Mark S Lachs, Stephen W HargartenAbstract:Background Photographing injuries in the acute setting allows for improved documentation as well as assessment by clinicians and others who have not personally examined a patient. This tool is important, particularly for telemedicine, tracking of wound healing, the evaluation of potential abuse, and injury research. Despite this, protocols to ensure standardization of Photography in clinical practice, forensics, or research have not been published. In preparation for a study of injury patterns in elder abuse and geriatric falls, our goal was to develop and evaluate a protocol for standardized Photography of injuries that may be broadly applied. Methods We conducted a literature review for techniques and standards in Medical, forensic, and legal Photography. We developed a novel protocol describing types of photographs and body positioning for eight body regions, including instructional diagrams. We revised it iteratively in consultation with experts in Medical Photography; forensics; and elder, child, and domestic abuse. The resulting protocol requires a minimum of four photos of each injury at multiple distances with and without a ruler/color guide. To evaluate the protocol's efficacy, multiple research assistants without previous Photography experience photographed injuries from a convenience sample of elderly patients presenting to a single large, urban, academic emergency department. A selection of these patients' images were then evaluated in a blinded fashion by four nontreating emergency medicine physicians and the inter-rater reliability between these physicians was calculated. Results Among the 131 injuries, from 53 patients, photographed by 18 photographers using this protocol, photographs of 25 injuries (10 bruises, seven lacerations, and eight abrasions) were used to assess characterization of the injury. Physicians' characterizations of the injuries were reliable for the size of the injury (κ = 0.91, 95% confidence interval [CI] = 0.77 to 1.00), side of the body (κ = 0.97, 95% CI = 0.88 to 1.00), precise location of the injury (κ = 0.74, 95% CI = 0.63 = 0.81), and type of abrasion (κ = 0.76, 95% CI = 0.45 to 1.00). The exact shape of the injury (κ = 0.44, 95% CI = 0.17 to 0.51), and the primary color of bruises (κ = 0.37, 95% CI = 0.25 to 0.48) were not as reliably characterized. Conclusions Standardizing the documentation of injuries with photographs for clinical and research assessment can be conducted by nonprofessional photographers. A Photography protocol will ensure that this important mechanism for documentation is optimized.

Staged Treatment of Temporomandibular Joint Ankylosis With Micrognathia Using Mandibular Osteodistraction and Advancement Genioplasty
Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons, 2012Co-Authors: Songsong Zhu, Tao Wang, En Luo, Lin XiaoAbstract:Purpose Distraction osteogenesis can be used to correct micrognathia after temporomandibular joint (TMJ) ankylosis. However, there is still some controversy over the proper sequencing of management for the ankylosed patients. The objective of the present study was to evaluate a staged treatment of TMJ ankylosis accompanied by micrognathia using arthroplasty, mandibular distraction osteogenesis, and advancement genioplasty. Patients and Methods A total of 12 bilateral TMJ ankylosis patients with micrognathia (aged 17 to 27 years) underwent arthroplasty as the initial surgical procedure, followed by orthodontic treatment and correction of mandibular micrognathia by osteodistraction and advancement genioplasty as the second surgical procedure. The clinical results were evaluated by mouth opening, radiography, Medical Photography, and respiratory function. Results The patients were followed up for a minimum of 8 months to a maximum of 36 months. The TMJ ankylosis was released successfully in all the patients, showing an increase in average mouth opening from 3.3 mm preoperatively to 35.8 mm postoperatively. Micrognathia was corrected, and, remarkably, the obstructive sleep apnea and hypopnea syndrome was cured. Satisfactory occlusion was achieved with orthodontic treatment. Conclusions Our data suggest that a staged and surgical orthodontic treatment might be a better approach to manage TMJ ankylosis accompanied by mandibular hypoplasia. In addition to mandibular osteodistraction, advancement genioplasty should be considered for better improvement in facial esthetics and respiratory function.

two stage treatment protocol for management of temporomandibular joint ankylosis with secondary deformities in adults our institution s experience
Journal of Oral and Maxillofacial Surgery, 2011Co-Authors: Songsong Zhu, En Luo, Ge FengAbstract:Purpose Treatment of adult patients with temporomandibular joint (TMJ) ankylosis and secondary deformities is a challenging problem. Although various techniques, including arthroplasties, orthognathic surgery, autogenous bone graft, and distraction osteogenesis, have been described for the management of patients with this condition, an appropriate treatment protocol has not been established. The purpose of this report is to describe a 2-stage treatment protocol, comprising TMJ reconstruction as the initial surgery, followed by orthodontic treatment, and correction of secondary deformities as the second surgery, for the management of TMJ ankylosis with secondary deformities in adults. Patients and Methods From January 2003 to December 2009, 24 adult patients (30 joints) with TMJ ankylosis and secondary deformities underwent TMJ reconstruction as the initial surgery, followed by orthodontic treatment and correction of secondary deformities as the second surgery. Clinical outcome was assessed based on oral function, radiography, and Medical Photography. Results Patients were followed up for a minimum of 12 months to a maximum of 32 months (mean, 18.6 months). No relapse of TMJ ankylosis occurred in any patient during the follow-up period. Oral function and skeletal deformities were significantly improved in all patients. Satisfactory occlusion was achieved with the help of orthodontic treatment. Most of the patients were satisfied with the final outcome. Conclusions The 2-stage treatment protocol described not only restores oral function but also improves the patient's esthetic appearance. We believe that it is a good approach for management of TMJ ankylosis with secondary deformities in adult patients.

the art and science of Photography in hand surgery
Journal of Hand Surgery (European Volume), 2014Co-Authors: Keming Wang, Evan Kowalski, Kevin C ChungAbstract:High-quality Medical Photography plays an important role in teaching and demonstrating the functional capacity of the hands as well as in medicolegal documentation. Obtaining standardized, high-quality photographs is now an essential component of many surgery practices. The importance of standardized Photography in facial and cosmetic surgery has been well documented in previous studies, but no studies have thoroughly addressed the details of Photography for hand surgery. In this paper, we provide a set of guidelines and basic camera concepts for different scenarios to help hand surgeons obtain appropriate and informative high-quality photographs. A camera used for Medical Photography should come equipped with a large sensor size and an optical zoom lens with a focal length ranging anywhere from 14 to 75 mm. In a clinic or office setting, we recommend 6 standardized views of the hand and 4 views for the wrist; additional views should be taken for tendon ruptures, nerve injuries, or other deformities of the hand. For intraoperative pictures, the camera operator should understand the procedure and pertinent anatomy in order to properly obtain high-quality photographs. When digital radiographs are not available and radiographic film must be photographed, it is recommended to reduce the exposure and change the color mode to black and white to obtain the best possible pictures. The goal of Medical Photography is to present the subject in an accurate and precise fashion.
