The Common

Background Tendinosis in the common extensor tendon and accompanying ligament, bone, and plica abnormalities can be observed on magnetic resonance imaging (MRI). Purpose To determine whether there is a difference between accompanying abnormalities according to the degree of common extensor tendon injury Material and Methods Patients who underwent 1.5-T MRI tests with a prediagnosis of lateral overuse syndrome were retrospectively reviewed, and 56 patients who had an injury in the common extensor tendon (CET) were included. The degree of tendon and ligament injury, muscle signal change, bone marrow signal change, presence of joint effusion, and morphological features in the presence of plica were evaluated via MRI examinations of the elbow. Results Overall, 32, 16, and eight patients had mild, moderate, and severe CET damage, respectively. As the severity of CET damage increased, the presence of joint effusion, and the presence and degree of damage to the lateral ulnar collateral ligament (LUCL) and radial collateral ligament (RCL) increased. The radiohumeral (RH) plica area was significantly larger in the group with mild CET damage. There was no statistically significant correlation between the severity of CET damage and the end of RH plica with a blind-end, coverage of one-third or more of the radius, its signal, thickness, and presence of olecranon fold. Conclusion As the severity of CET injury increases, damage to the LUCL, RCL, and the presence of effusion in the joint increases. RH plica should be evaluated in terms of concomitant pathology in patients with mild CET injuries on MRI.

Background The elbow is one of the most commonly dislocated joints, and dislocation is usually accompanied with an assortment of soft tissue injuries. The purpose of this study was to retrospectively analyze and describe the patterns of ligamentous, tendinous, and muscular injuries in patients with an acute elbow dislocation and subsequent magnetic resonance image (MRI) evaluation. Methods From 2008 to 2020, 235 patients clinically diagnosed with an elbow dislocation were seen in the department, of which only 19 underwent an MRI of the affected elbow. Twelve patients met inclusion criteria, and MRIs were evaluated by both a radiologist and an upper extremity orthopedic surgeon. Magnetic resonance images were assessed for injury to the ulnar collateral ligament (UCL); radial collateral ligament (RCL); lateral ulnar collateral ligament (LUCL); common flexor and extensor tendons; biceps, brachialis, and triceps tendons; fracture; and joint effusion. Results Magnetic resonance imaging findings included the following: UCL was injured in 11 of 12 patients; RCL was injured in 9 of 12 patients; LUCL was injured in 9 of 12 patients; common flexor tendon was injured in 11 of 12 patients; and common extensor tendon was injured in 9 of 12 elbows. The biceps, brachialis, and triceps tendons showed injury in 1 of 12, 2 of 12, and 2 of 12 elbows, respectively. Four elbows had at least 1 fracture present, whereas 8 demonstrated an effusion. Conclusions In this series, injuries to the UCL and common flexor tendon were most common. Although ligamentous injuries are exceedingly common in elbow dislocations, large studies of MRI findings prove difficult due to MRI costs.

Background: Patellofemoral pain is the leading cause of knee pain in young adults. Magnetic resonance imaging plays an important role in early diagnosis of patellofemoral joint pathology. This study was carried out to evaluate the patellofemoral joint using magnetic imaging resonance and describe various predisposing factors for patellofemoral instability. Methods: The study was carried in Department of Radiology, BPKIHS over a period of six months from February 2020 to August 2020. All patients with clinical diagnosis of patellar instability were included and Magnetic resonance imaging was done using standard knee protocol and findings were noted on structured proforma. Analysis was done using statistical package for the social sciences version 20 applying simple descriptive statistical methods.Results: A total of 60 patients who underwent MRI knee were analyzed, out of which 28(46.7%) patients were male while 32(53.3%) patients were female. 44 patients (58.3%) had various predisposing factors for patellar instability. The commonest predisposing factor was patellar subluxation (73.3%) followed by abnormal trochlear groove angle (58.3%) and patellar translation (increased tibia tubercle trochlear groove distance) (53.3%). Various MRI findings in our study were bone contusion (28 cases,46.7%), joint effusion (36 cases,60%), medial patellofemoral ligament injury (11cases ,18.3%), erosion of patellar cartilage (5 cases,8.3%), femoral cartilage erosion (3 cases,5%),loose bodies (2 cases,3.3%), subchondral edema (3 cases,5%) and meniscus injury (18 cases,30%).Conclusions: Magnetic resonance imaging is not only useful in assessing lesions of the bone, cartilage and ligaments of patellofemoral joint but also enables detection of various predisposing factors for patellofemoral instability.Keywords: Magnetic resonance imaging; patellofemoral instability; patellofemoral joint

The paper considers some articulatory features of allophones of the vowel /i/ in the Altai-Kizhi dialect (spoken in the locality Ust-Kan, Altai) of the Altai language visualized by magnetic resonance imaging (MRI). The Altai-Kizhi is the central basic dialect of the Altai literary language. In Altai, each rural locality represents a unique dialect, whose relevance of studying was emphasized by V. V. Radlov. Speech sounds of the /i/-type in the dialects of the Altai language are realized mainly as front variants with different degrees of openness. In the written Altai speech, the symbol “и” is used to denote narrow front non-labialized vowel; some variants of the Altai vowel /i/ are central-back differing in this from the Russian vowel /i/. Experimental data on the territorial dialects of the Altai-Kizhi dialect, obtained from its 6 native speakers (d1-d6) taking into account variable inherent palate height, shows both the common articulation bases of native speakers (clearly-expressed frontness) and their differences (variable openness).

Abstract Background Magnetic resonance is the best imaging modality to assess hip joint in non-traumatic cases. It has a great ability to diagnose disorders of bone, cartilage, ligaments, muscles and soft tissue. MRI can also detect joint effusion and bone marrow edema. Aim of the Work: To assess the value of MRI as the imaging modality in children presenting with acute non-traumatic hip pain and its ability to assess the cause of the pain early without the use of another imaging modality. Patients and Methods A retrospective study was conducted on pediatric patients with non-traumatic hip pain, referred from the outpatient pediatric clinic, orthopedic clinic, Ain Shams University hospitals. The patients were investigated using magnetic resonance imaging (MRI) for detection the cause of non-traumatic hip pain. Results In this study we found that avascular necrosis is the commonest cause of non-traumatic hip pain followed by isolated hip effusion then synovitis. Other causes included perthes, septic arthritis, osteomyelitis, aneurysmal bone cyst, SCFE, PFFD and Osteomalacia. Magnetic resonance imaging doesn’t only demonstrate disorders of hip joint only; it also gives an accurate assessment of other extra-articular causes of referred hip pain. Conclusion Hip MRI is a practical, well accepted and accurate non-invasive imaging technique in children presenting with acute non-traumatic hip pain.
