Extensor Tendon Injuries

AbstractTendon injuries represent the second most common injury of the hand (after fractures) and are a common scanning indication in radiology. Pulley injuries are very frequent in rock climbers with the A2 pulley the most commonly affected. Tendon and pulley injuries can be reliably evaluated using ultrasound (US) and magnetic resonance imaging (MRI). US can be postulated as a first-line imaging modality, allowing dynamic examination. MRI is essential for cases with ongoing diagnostic doubt post-US and also for preoperative pulley reconstruction assessment.

AbstractPediatric patients often present to the emergency department with a wide variety of infectious, inflammatory, and neoplastic lesions of the head and neck. Evaluation of pediatric patients in the emergency setting is complicated by limited history and physical examination. Imaging plays an important role in arriving at an accurate diagnosis. The fascial spaces and compartments of the neck provide an approach to differential diagnosis, and knowledge of the typical clinical and imaging manifestations of common pediatric head and neck emergencies allows the radiologist to identify the condition and associated complications that may require emergent surgical management. Computed tomography (CT) is the first-line imaging modality in the emergency setting; however, magnetic resonance imaging (MRI) plays an important secondary role.

Orbital Hematoma

Proptosis in the neonatal period is relatively infrequent and has diverse underlying etiologies. One of the more common causes appears to be orbital subperiosteal hematoma. Early detection, differentiation from other causes, and regular follow-up are essential as loss of vision can occur. We describe two cases of neonatal proptosis caused by orbital subperiosteal hematoma highlighting different diagnostic and management approaches, and provide a summary of previously reported cases. Spontaneous resolution occurs in most cases; however, emergent surgical evacuation is warranted in cases of optic nerve compression. This is the first report to provide orbital ultrasound images of uncomplicated neonatal orbital subperiosteal hematoma. Orbital ultrasound followed by magnetic resonance imaging (MRI) is a valid nonradiation approach for assessing neonatal proptosis due to subperiosteal orbital hematoma.

AbstractObjective:We report two cases of branchial cleft abnormalities investigated using magnetic resonance imaging.Background:There appears to be no clear imaging technique that is universally recommended for imaging branchial cleft abnormalities. Options include fistulography, computed tomography, magnetic resonance imaging and ultrasonography.Method:Case reports and literature review.Case reports:Two cases, although not unusual in themselves, are described to illustrate the use of magnetic resonance imaging to define the anatomy and to assist surgical planning.Conclusion:Magnetic resonance imaging is able to accurately depict the extent and course of branchial cleft abnormalities, and in the current cases could have been relied upon to determine the necessary surgical procedure. Branchial cleft abnormalities are sufficiently rare for magnetic resonance imaging to be recommended as the first-line imaging modality.

Background The latest International Myeloma Working Group (IMWG) guideline recommends low-dose whole-body (WB) computed tomography (CT) as the first-line imaging technique for the initial diagnosis of plasma cell disorders. Purpose To evaluate diagnostic performances of CT and diffusion-weighted imaging (DWI) as the first-line imaging modalities and assess misclassification rates obtained following the guideline. Material and Methods Two independent radiologists analyzed CT (acquired as PET/CT) and DWI (3-T; b-values = 50 and 900 s/mm2) of patients newly diagnosed with plasma cell disorder, categorizing the number of bone lesions. Diagnostic performance of CT and DWI was compared using the McNemar test, and misclassification rates were calculated with a consensus WB-MRI reading as the reference standard. Differences in lesion number categories were assessed using marginal homogeneity and kappa statistics. Results Of 56 patients (36 men; mean age = 63.5 years), 39 had myeloma lesions. DWI showed slightly higher sensitivity for detecting myeloma lesions (97.4%) than CT (84.6%–92.3%; P > 0.05). CT showed significantly higher specificity (88.2%) than DWI (52.9%–58.8%; P<0.05). CT had a higher additional study requirement rate than DWI (7.7%–15.4% vs. 2.6%), but a lower unnecessary treatment rate (11.8% vs. 41.2%–47.1%). Both readers showed significant differences in categorization of the number of lesions on CT compared with the reference standard ( P < 0.001), and one reader showed a significant difference on DWI ( P = 0.006 and 0.098). Conclusion CT interpreted according to the IMWG guideline is a diagnostically effective first-line modality with relatively high sensitivity and specificity. DWI alone may not be an acceptable first-line imaging modality because of low specificity.

Extensor Tendon Injuries

This retrospective study evaluates a dynamic active motion protocol for extensor tendon repairs in zones V to VII. Fifty-eight patients with 87 extensor tendon injuries were examined. Using Geldmacher’s and Kleinert and Verdan’s evaluation systems, the results were graded as “excellent” and “good” in more than 94%, and as “satisfactory” in the remainder. The need for secondary tenolysis was low (6%), and no other surgical complication occurred.

AbstractThe motor function of the thumb and its alignment with regard to the hand make it particularly vulnerable to trauma. Pathology encountered in this joint is varied, and imaging techniques play a crucial role in the diagnosis and characterization of injury. Despite advances in imaging technology, acute thumb injuries remain a challenge for radiologists. Currently, standard radiography and ultrasonography are frequently used first-line imaging techniques. Computed tomography is most often indicated for complex fractures and dislocations. Magnetic resonance imaging may be used to optimally characterize soft tissues and bone marrow. In this article, we cover the most common traumatic injuries: fractures, dislocations, collateral ligament injuries of the metacarpophalangeal joint, as well as soft tissue lesions.

Mri Evaluation

Occlusal stabilization appliances or splints are the most widely employed method for treatment of temporomandibular disorders (TMD). Magnetic Resonance Imaging (MRI) is the most indicated imaging modality to evaluate the components of the temporomandibular joint (TMJ). Forty patients with signs and symptoms of temporomandibular disorders were treated with splints for a mean period of 12 months, comprising regular semimonthly follow-ups. After stabilization of the clinical status, occlusal adjustments and MRI evaluation were performed. It was concluded that the success of this kind of treatment are related to the total (70%) or partial improvement (22.5%) of painful symptomatology and to the functional reestablishment of the craniomandibular complex. The MRI allowed evaluation and also the conclusion that the splints provide conditions for the organism to develop means to resist to the temporomandibular disorders by means of elimination of several etiologic factors. Moreover, after treatment the patients are able to cope with disc displacements with larger or smaller tolerance.
