Frozen shoulder after COVID-19 vaccination versus idiopathic frozen shoulder: similar clinical features and functional improvement at 1-year follow-up.

Background: Frozen shoulder after COVID-19 vaccination is sparsely discussed in the medical literature. We aimed to evaluate: (1) the differences in the baseline clinical features and functional outcomes of conservatively treated frozen shoulder following COVID-19 vaccination compared to idiopathic frozen shoulder (2) the improvements in pain scores, functional outcomes, and range of motion (ROM) at 6-10 months and at 1 year of follow-up in patients with frozen shoulder after COVID-19 vaccination treated by conservative therapy. Methods: Between June 2021 and December 2021, 12 patients (13 shoulders) that were diagnosed with frozen shoulder after COVID-19 vaccination (vaccine related frozen shoulder [VRF] group) (final follow-up of 12.4 months ± 0.8 months) were compared with 20 patients that were diagnosed as idiopathic frozen shoulder unrelated to vaccination (unvaccinated frozen shoulder [UFS] group) (average follow-up of 13.4 ± 3.1 months). All patients were treated with home-based stretching exercises. Four (33%) patients in the VRF group and 15 (75%) patients in the UFS group underwent steroid injection in the suprascapular notch by an experienced radiologist. Results: The left side was affected more frequently in the VRF group [n = 10 (83.3%)] than in the UFS group [n = 8 (40%), P = .03]. The VRF and the UFS groups were similar in the rest of the baseline clinical features, such as the age distribution, men/women ratio, baseline Oxford Shoulder Scores (OSS), ROM deficit, and pain visual analogue scale (VAS) scores. The OSS, VAS pain scores, and the ROM deficit significantly improved in the VRF group at the 6-10-month follow-up and then at the final (12.4 ± 0.8 months) follow-up compared to the baseline values. At the final follow-up, there were no significant differences in the average external rotation, external rotation deficit, elevation, elevation deficit, internal rotation, pain VAS scores, and OSS between the VRF and the UFS group. Conclusion: To conclude, frozen shoulder following COVID-19 vaccination may present with clinical features similar to those of the idiopathic frozen shoulder. Furthermore, the patients with frozen shoulder following COVID-19 vaccination may continue to improve over one year with conservative treatment; the final improvements in function and ROM are similar to those with idiopathic frozen shoulder.

Morphometric Analysis of Ulnar Variance and Its Demographic Dynamics Using High Resolution MRI: A Retrospective Study in Indian Population and Review of Literature.

Background: Ulnar variance (UV) is the variation of the level of the distal articulating surface of the radius with respect to the distal articulating surface of the ulna. These variations either positive or negative can predispose to pathologies involving the wrist joint. The aim of this study was to measure the ulnar variance in a subset of Indian population using high-resolution MRI and compare our results with the existing literature. Materials and Methods: Retrospective analysis of 100 normal wrist MRIs were done performed during November 2020 to November 2021 and the ulnar variance was calculated using the Method of Perpendiculars. All the MRI sequences were performed by an experienced radiologist with prior fixed protocol for the study. The measurements were done on the mid-coronal section based on the Method of Perpendiculars using Meddiff Rispacs software. Results: The average age of the participants was 42 years, with Male to female ratio of 0.9:1. 47 MRIs were of the left wrist, while 53 MRIs were of the right wrist. The mean UV was - 0.7 mm (SD-0.175), ranging from - 4.5 mm to 3.5 mm. There was a significant relationship between ulnar-variance and age, as ulnar-variance increases with the age (p value = 0.039). There was no statistically significant correlation of ulnar-variance with gender distribution and handedness. Conclusions: This study utilized high-resolution MRI for measuring ulnar-variance in a subset of Indian population and disclosed that the ulnar-variance affirms a positive correlation with age, while no specific pattern between the ulnar-variance and gender or handedness could be established.

Obturator Internus Bursitis Mimicking Groin Pain in a Football Player: A Case Report.

Introduction: Traumatic groin pain (GP) is frequently the result of acute trauma, often an indirect muscle injury. The most affected muscles in traumatic GP are the rectus abdominis, adductors, and iliopsoas. The obturator internus bursitis as a cause of GP is very rare. Case Presentation: The present case describes a rare indirect injury of obturator internus bursitis in a 22-year-old male football player who reported GP that used to worsen with sprinting and change in directions. The pain was relieved with rest and sprinting at 80% capacity. The patient had been diagnosed clinically and on magnetic resonance imaging (MRI) as a case of obturator internus insertional tendinopathy with bursitis. His symptoms resolved after ultrasound-guided injection in the inflamed tendon sheath at its insertion point. After 2 years, the patient was followed up with a triumphant return to professional football with no recurrence and a good prognosis in a relatively short recovery time. Conclusion: Clinical diagnosis of obturator injuries is often tricky. GP not responding to conservative management presents a unique challenge to the physician and the rehabilitation team. MRI must follow the radiological investigations and ultrasound if the reports were inconclusive of the diagnosis. In the present case study, the usual causes of such pain (osteitis pubis, and adductor muscle strains/tendinosis) were ruled out, and a specific unique condition was diagnosed with the help of the MRI.

Clinical Profile of Patients with Severe Acute Respiratory Syndrome Coronavirus 2 Infection Developing Pulmonary Barotrauma on Mechanical Ventilation.

Background: There is limited information on clinical profile and outcomes of patients on mechanical ventilation (MV) who developed pulmonary barotrauma (PBT) in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Patients and methods: In a retrospective observational study, all SARS-CoV-2 pneumonia patients admitted from March 28, 2020, to August 31, 2020, at Sir HN Reliance Foundation Hospital and Research Center and Seven Hills Hospital (Reliance Facility), Mumbai, India, of 18 years and above on MV and developed PBT, were included. Results: A total of 14 SARS-CoV-2 patients of 45 on MV (31.0%) developed PBT of 1,029 hospitalized. All patients were male and divided as per admission into PaO2/FiO2 (P/F) ≤100 (median 80) and P/F >100 (median 222) group. Pneumothorax developed in seven and six cases of P/F ≤100 and P/F >100 groups, respectively. Three patients in each group developed subcutaneous emphysema, while four developed pneumomediastinum in P/F >100 group. Twelve patients (7, P/F ≤100, and 5, P/F >100) were on invasive, while two (P/F >100) were on noninvasive MV. The mean P/F on the day of PBT was reduced by 27.5 and 65.3%, while peak inspiratory pressure was elevated with a median of 36 and 28 cm H2O in P/F ≤100 and P/F >100 groups, respectively. The median highest tidal volume (420 mL), positive-end expiratory pressure (8 vs 6 cm H2O) on the day of PBT, and length of hospital stay (11 vs 25 days) did not differ between two groups. Survival was 28.6% (4/14). Conclusion: SARS-CoV-2 patients requiring MV with PBT had poor outcomes. Clinicians should be vigilant about the diagnosis of PBT.

Imaging of Coronavirus Disease 2019 Infection From Head to Toe: A Primer for the Radiologist.

Coronavirus Disease 2019 (COVID-19) disease has rapidly spread around the world after initial identification in Wuhan, China, in December 2019. Most common presentation is mild or asymptomatic disease, followed by pneumonia, and rarely- multiorgan failure and Acute Respiratory Distress Syndrome (ARDS). Knowledge about the pathophysiology, imaging and treatment of this novel virus is rapidly evolving due to ongoing worldwide research. Most common imaging modalities utilized during this pandemic are chest radiography and HRCT with findings of bilateral peripheral, mid and lower zone GGO and/or consolidation, vascular enlargement and crazy paving. HRCT is also useful for prognostication and follow-up of severely ill COVID-19 patients. Portable radiography allows follow-up of ICU patients & obviates the need of shifting critically ill patients and disinfection of CT room. As the pandemic has progressed, numerous neurologic manifestations have been described in COVID-19 including stroke, white matter hyperintensities and demyelination on MRI. Varying abdominal presentations have been described, which on imaging either show evidence of COVID-19 pneumonia in lung bases or show abdominal findings including bowel thickening and vascular thrombosis. Numerous thrombo-embolic and cardiovascular complications have also been described in COVID-19 including arterial and venous thrombosis, pulmonary embolism and myocarditis. It is imperative for radiologists to be aware of all the varied faces of this disease on imaging, as they may well be the first physician to suspect the disease. This article aims to review the multimodality imaging manifestations of COVID-19 disease in various organ systems from head to toe.

Posterior Circulation Stroke due to Atlantoaxial Instability in CHST3-Related Skeletal Dysplasia: A Case Report.

CASE: An eight-year-old boy presented with acute encephalopathy due to posterior circulation ischemic stroke. He was found to have vertebral artery stenosis secondary to atlantoaxial instability (AAI) due to an os odontoideum. Occipitocervical fusion was performed 4 weeks after stroke. The child improved neurologically and regained independent ambulation. He had indications of an underlying spondyloepiphyseal dysplasia with joint luxation and whole-exome sequencing diagnosed CHST3-related skeletal dysplasia. CONCLUSION: As far as we know, this AAI due to an os odontoideum is a previously unreported complication of CHST3-related skeletal dysplasia. Occipitocervical fusion yielded good clinical results with the 1-year follow-up.

Novel arterioplasty of severe left pulmonary artery stenosis using native main pulmonary artery.

There are multiple approaches described for the repair of stenosed branch pulmonary arteries. Regardless of the technique used, restenosis is common. We describe a case of severe left pulmonary artery stenosis repaired with a novel technique using the native main pulmonary artery which was transected and turned down to create a direct anastomosis with the left pulmonary artery. This tension-free tissue to tissue anastomosis resulted in hemodynamically gratifying results with the potential for growth.

One stage combined repair of intracardiac defects with vascular ring employing sternotomy approach.

We present an unusual case of atrial septal defect and ventricular septal defect with a vascular ring formed by a right-sided aortic arch with an aberrant left subclavian artery that gave rise to a patent ductus arteriosus connecting to the main pulmonary artery. We performed a single-stage repair of the intracardiac defects and division of vascular ring with a sternotomy instead of the traditionally practiced dual approach. This included division and reimplantation of the aberrant left subclavian artery to the left carotid artery after transection. This approach has not been described so far.

The feasibility of direct adductor canal block (DACB) as a part of periarticular injection in total knee arthroplasty.

BACKGROUND: Adductor canal block (ACB) is one of the preferred methods of analgesia in total knee arthroplasty (TKA). However, conventionally its use is time-consuming, requires ultrasound guidance, a trained anaesthesia team and adherence to strict asepsis by members of the allied teams. This study was done to assess the feasibility and safety of direct adductor canal block (DACB) as a part of surgeon-administered periarticular infiltration. MATERIALS AND METHODS: Thirty computed tomography (CT) angiography films of the patients were retrospectively reviewed. The trajectory of the needle placement for a DACB in relation to the target region of the adductor block was determined. Fourteen knees in seven cadavers, were dissected through a medial parapatellar approach to perform TKA. After administering the DACB using the technique based on CT data, dissection was carried out to ascertain the correct placement of the dye by visualising the stained areas. RESULTS: The angle of approach in the coronal plane from the entry point to the medial high point and to the adductor hiatus was 10.2° (8-14°) and 6° (3.8-11°), respectively. The angle of approach in the sagittal plane from the entry point to the medial high point and to the adductor hiatus was 7° (5-10.5°) and 29° (19-43°), respectively. In all the 14 cadaveric knees, we confirmed the correct placement of the methylene blue dye as demonstrated by the staining of the adductor canal. CONCLUSION: The study demonstrates the feasibility of the DACB. This surgeon-driven technique is likely to reduce the cost of the procedure, reduce operating room time and also eliminate the risks of surgical-site contamination.

Magnetic resonance imaging evaluation after anorectal pull-through surgery for anorectal malformations: a comprehensive review.

Anorectal malformations (ARM) include congenital anomalies of the distal anus and rectum with or without anomalies of the urogenital tract. Posterior sagittal anorectoplasty (PSARP) and minimally invasive laparoscopically assisted anorectal pull-through (LAARP) procedure are now mainly used to surgically treat ARMs. Magnetic resonance imaging (MRI) is the modality of choice for interval follow-up assessment of structural and functional outcome after these surgeries to assess future bowel continence. Well-developed pelvic musculature has been found to be a reflector of better anal continence after ARM surgery. Thus, MRI plays an important role in evaluating the external sphincter complex, puborectalis, and levator ani muscles. Other parameters that need to be noted include the position of the neoanus, rectal diameter, anorectal angle, presence or absence of megarectum, and other ancillary anomalies in the spine. Thus, MRI due to superior soft-tissue resolution is the modality of choice and indispensable for post-operative pelvic evaluation in children.
