BACKGROUND: Heterotopic ossification (HO) is defined as ectopic bone formation following traumatic brain injury. Patients typically develop lesions in the hips, knees, and elbows that cause pain, restricted range of motion, nerve impingement, and pressure ulcers. CASE REPORT: We report an unusual presentation of HO in an 18-year-old male who was involved in a motor vehicle accident and subsequently developed malignant intracranial pressure. His HO developed following bilateral craniectomies in which 2 different dural substitutes were used...

BACKGROUND: Osteochondritis dissecans (OCD) lesions are often observed in the humeral capitellum both in young baseball players and gymnasts. It is generally believed that capitellar OCD in baseball players can be seen on an anteroposterior (AP) radiograph with the elbow in 45° of flexion. However, the mechanism of injury seems to be different in baseball players and gymnasts. Repetitive valgus overload with the elbow in flexion is believed to be the cause of capitellar OCD lesions in baseball players, whereas weightbearing with the elbow in extension may be the cause of OCD in gymnasts...

OBJECTIVE: To analyze patterns of nerve injury in pediatric ulnar neuropathy (PUN). METHODS: Retrospective analysis of 49 children with PUN. RESULTS: Sensory loss in digit V was the prevailing complaint (89%). Predominant localization was at the elbow (55%). Diminished ulnar SNAP was the most common abnormality (71%) with median axon loss estimate (MAXE) of 62%. Dorsal ulnar cutaneous (DUC) sensory nerve action potential (SNAP) was reduced in 55% with MAXE of 43%...

PURPOSE: Which infants with brachial plexus birth palsy (BPBP) should undergo microsurgical plexus reconstruction remains controversial. The current gold standard for the decision for plexus reconstruction is serial clinical examinations, but this approach obviates the possibility of early surgical treatment. We hypothesize that a new technique using 3-dimensional volumetric proton density magnetic resonance imaging (MRI) without sedation can evaluate the severity of BPBP injury earlier than serial clinical examinations...

Recovery after surgical reconstruction of a brachial plexus injury using nerve grafting and nerve transfer procedures is a function of peripheral nerve regeneration and cerebral reorganization. A 15-year-old boy, with traumatic avulsion of nerve roots C5-C7 and a non-rupture of C8-T1, was operated 3 weeks after the injury with nerve transfers: (a) terminal part of the accessory nerve to the suprascapular nerve, (b) the second and third intercostal nerves to the axillary nerve, and (c) the fourth to sixth intercostal nerves to the musculocutaneous nerve...

Longxiang Shen, Xingang Yu, Biao Zhong, Jian Ding
PURPOSE: Sufficient fixation of an anterior or anteromedial facet fracture of the coronoid process in fracture-dislocation of elbow is important to maintain joint stability. The purpose of this study was to report our experience with 11 patients who were managed with an original fixation technique using a "figure-eight" suture loop. METHODS: From February 2010 to March 2011, 11 cases with a fracture of the anterior or anteromedial facet of the coronoid process were treated by coronoid fixation using a figure-eight suture loop...

AIM OF SURGERY: Reconstruction of the most important ligamentous and osseus structures of the elbow after terrible triad injury via the radial head to the lateral collateral ligament complex (LCL) and if necessary beginning at the coronoid process. The aim is a stable concentrically guided elbow with early functional follow-up treatment. The approach depends on the intraoperatively tested stability. INDICATIONS: Osteoligamentous terrible triad injury pattern with or without subluxation position following reduction and temporary immobilization...

Simultaneous Monteggia injuries of the elbow and ipsilateral fracture distal radius with epiphyseal injury both bone are a unique case. A unique case of a Type I Monteggia fracture equivalent with ipsilateral fracture distal radius with epiphyseal injury (Salter-Harris Type II) in a child is reported. We describe the management of this unique fracture and discuss the possible mechanism of injury. We have highlighted a rare combination of injuries. Early recognition and prompt surgical intervention can lead to a satisfactory outcome even in these complex injuries...

The overhead-throwing athlete is susceptible to a variety of predictable disease entities affecting the shoulder and elbow. While the pathophysiology and nomenclature of these diseases are ubiquitous throughout the clinical literature, this information is sparse within the radiology domain. We provide a comprehensive review of these unique injuries with accompanying imaging features in an effort to enhance the role of the radiologist during the management of the overhead thrower. When appropriately recognized and described, the imaging features aid in establishing a diagnosis and ultimately the implementation of appropriate clinical management...

BACKGROUND: The windmill pitching motion has been associated with risk for shoulder injury. Because there are no pitching limits on youth fast-pitch softball pitchers, these athletes often pitch multiple games across consecutive days. Strength changes, fatigue levels, and shoulder pain that develop among female fast-pitch pitchers over the course of consecutive days of pitching have not been investigated. HYPOTHESIS: Over the course of 2- and 3-day fast-pitch softball tournaments, pitchers will develop progressive objective weakness and increased subjective shoulder fatigue and pain without complete recovery between days...

RATIONALE: Elbow injury in children by improper treatment or a delay of more than 3 weeks could lead to old unreduced Monteggia fracture, which are difficult to manage. Conservative or normal surgical methods usually fail. PATIENT CONCERNS: Herein, we present a 6-year-old boy with sustaining injury approximately 1 month to his left elbow. Activity in his elbow was restricted, and his ability to extend his wrist and fingers was impaired. DIAGNOSES: Type III Monteggia elbow fracture-dislocation consisting of radial head dislocation and malunion of the ulna associated with posterior interosseous nerve palsy were confirmed, which requiring surgical treatment...

Objective: The latissimus dorsi flap is a workhorse for plastic surgeons, being used for many years for soft-tissue coverage of the upper extremity as well as for functional reconstruction to restore motion to the elbow and shoulder. The authors present a case of functional latissimus dorsi transfer for restoration of elbow flexion and review the literature on technique and outcomes. Methods: A literature review was performed using MEDLINE and the Cochrane Collaboration Library for primary research articles on functional latissimus dorsi flap transfer...

BACKGROUND: Severely displaced supracondylar fractures of the humerus in children are frequently associated with complications including neurovascular injuries, non-union, or compartment syndrome. In the current literature, no report exists about postoperative brachial artery entrapment in combination with an inconspicuous preoperative neurovascular examination. CASE PRESENTATION: We present a case of a 6-year-old white boy with a pulseless radial and ulnar artery after open reduction and internal fixation of a severely displaced supracondylar fracture of his right humerus (Gartland type III) using four K-wires...

Normal variations in anatomy in the skeletally immature patient may be mistaken for fracture or injury due to the presence of secondary centers of ossification. Variations in imaging exist from patient to patient based on sex, age, and may even vary from one extremity to the other on the same patient. Despite differences in the appearance of the bony anatomy of the elbow there are certain landmarks and relationships, which can help, distinguish normal from abnormal. We review common radiographic parameters and pitfalls associated in the evaluation of pediatric elbow imaging...

BACKGROUND: A subluxation of the radial head (SRH) is a clinical condition that commonly occurs in children under 6 years of age. History and physical examination findings typically include a child who presents with an elbow held in extension and with forearm pronation, after having suffered significant longitudinal traction on the arm, or after a fall on an outstretched hand. The diagnosis is often clinically obvious. The injury responds dramatically to closed reduction, and usually no imaging is required...

Elbow tendinopathy accounts for the majority of elbow pathology in patients presenting to upper extremity and sports medicine surgeons. With increased participation in overhead sports in an aging population, the incidence of elbow injuries has risen. A comprehensive knowledge of elbow anatomy and biomechanical function of the elbow complex is prerequisite in the assessment of patients with elbow injuries; however, a thorough understanding of alternative and confounding pathologies is essential for accurate diagnosis...

Hypermobility syndrome usually causes pain in limbs from extension type injuries. The authors report on a 16-yr-old female adolescent with incapacitating chest pain secondary to extreme hypermobility of the chest. This pain led the patient to see multiple specialists without improvement or diagnosis. Physical examination results revealed a very hypermobile patient who was able to internally rotate her shoulders inward until her elbows touched. This unusual hyperextension maneuver was achieved by holding the shoulders in anteversion with her hands on her hips (see figures in the article)...

Accurately predicting the occupant kinematics is critical to better understand the injury mechanisms during an automotive crash event. The objectives of this study were to develop and validate a finite element (FE) model of the human body integrated with an active muscle model called Total HUman Model for Safety (THUMS) version 5, which has the body size of the 50th percentile American adult male (AM50). This model is characterized by being able to generate a force owing to muscle tone and to predict the occupant response during an automotive crash event...

Human spinal cord injuries (SCI) disrupt the pathways between brain and spinal cord, resulting in substantial impairment and loss of function. Currently, we do not have the ability to precisely quantify the "functional" level of motor injury. The aim of this study is to determine if high-density surface electromyography imaging (SEI) can be used to characterize the location and extent of the spinal lesion. SEI is a safe and non-invasive technique, which uses several electrodes to provide a map of muscle activity...

PURPOSE: Perception of action capabilities can be altered by changes in sensorimotor processes, as showed in previous works in populations dealing with regular and pathological sensorimotor deficits. Misestimating changes in performance ability could lead to risky behavior, injury, and/or reduced performance. However, the relationship between sensorimotor processes, the action-perception coupling, and the related anatomical structures is still a matter of debate. We investigated whether changes in the muscle-tendon system's mechanical properties experimentally induced by eccentric contractions could alter the action-perception coupling (APC) in a reaching-to-grasp task, in which the participants estimated the maximal distance they predicted that they would able to reach a glass...
