Reliability and Effectiveness of Smartphone Technology for the Diagnosis and Treatment Planning of Pediatric Elbow Trauma.

BACKGROUND: Mobile imaging, such as viewing radiographs as text messages, is increasingly prevalent in clinical settings. The purpose of this study was to determine whether remote diagnosis of pediatric elbow fractures using smartphone technology is reliable. In addition, this study aimed to determine whether the assessment regarding the decision for operative treatment is affected by evaluation of images on a mobile device as opposed to standard picture archiving and communication system (PACS). METHODS: Standard anteroposterior and lateral radiographs of 50 pediatric elbow trauma cases were evaluated by 2 fellowship-trained pediatric orthopaedic surgeons and 2 senior orthopaedic residents. Raters were asked to classify the case as any of 6 diagnoses: supracondylar humerus, lateral condyle, medial epicondyle, radial neck fracture, positive posterior fat pad sign, or normal pediatric elbow. Raters were asked to choose operative or conservative treatment. After 1 week, photographs of the same images were taken from a standardized distance from a computer monitor with an iPhone 5 camera and transmitted by multimedia messaging to each rater. The same questions were again posed to raters. Interobserver and intraobserver reliabilities were calculated by Cohen κ-statistics with bootstrapped 95% confidence intervals. RESULTS: Intraobserver reliability of classification of injuries on PACS compared with smartphone images was excellent, with an overall κ of 0.91. Treatment decision also demonstrated excellent intraobserver reliability (PACS vs. smartphones) with a κ of 0.86 for all raters. CONCLUSIONS: Diagnosis of pediatric elbow injuries can be made equally reliably based on either PACS or transmitted multimedia messaging images taken with an iPhone camera from a computer screen and viewed on a smartphone. Treatment decisions can also be made reliably based on either image modality. CLINICAL RELEVANCE: Using smartphones to transmit and display radiographs, which is common in current clinical practice, is effective and reliable for diagnosis and treatment planning of pediatric elbow injuries.

Complications of pediatric supracondylar humeral fractures.

Supracondylar humeral fractures are common in the pediatric population and can result in complications caused by both the injury itself and surgical or nonsurgical treatment. Neurologic complications are frequent, with the anterior interosseous nerve being the most common nerve affected. Vascular injuries, although less common, can result in long-term sequelae and should be recognized and treated promptly. Loss of reduction can occur with both surgical and nonsurgical treatment. Compartment syndrome and infection, although rare, require rapid recognition and treatment. It is important to be familiar with the potential complications surrounding the treatment of pediatric supracondylar humeral fractures to maximize outcomes and know when a referral may be warranted.
