Acute monoarticular hip joint pseudogout masquerading as septic arthritis.

Monoarticular pseudogout of the hip joint is rare and to the best of our knowledge only four other cases exist in the literature. We present a case of primary monoarticular pseudogout affecting the right hip in a patient in his 50s. The diagnosis was confirmed through ultrasound-guided synovial fluid aspiration and crystal analysis. The patient was treated conservatively with analgesia and after hip joint aspiration resulted in dramatic symptomatic resolution. Acute attack of pseudogout is a rare cause of acute hip pain. The clinical features may mimic hip joint septic arthritis and should be considered in the differential diagnosis of any presentation of acute joint pain. Diagnosis is important to avoid unnecessary medical and surgical intervention reducing hospital stay.

A Case of Axial Spondyloarthritis Triggered by SARS-CoV-2 Infection.

Ever since the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there has been a noticeable change in atypical presentations of several rheumatological diseases following COVID-19 infections. In this case report, we present a case of SARS-CoV-2-induced axial and peripheral spondyloarthritis. This case highlights the possibility of SARS-CoV-2 infection accelerating the onset of autoimmune diseases such as axial spondyloarthritis. Although uncommon, these cases warrant a referral to the rheumatologist for appropriate diagnosis and management. This case also highlights the need for further research on the mechanisms behind the viral interaction of SARS-CoV-2 infections with the host immune system, especially about accelerating the onset of autoimmune diseases.

Tibia vara or Blount's disease: Why an early diagnosis and treatment are important?

Tibia vara is an asymmetrical disorder of the proximal tibia that produces a threedimensional deformity, which was first described by Blount in 1937. A 6-year-old boy presented with a history of anterior knee pain with progressive bowing of his right leg over the last 1 year after having a fall while playing soccer. An early diagnosis and treatment of this disease can have a great functional impact and lead to very good health outcomes.

Day case vs inpatient total shoulder arthroplasty: A retrospective cohort study and cost-effectiveness analysis.

BACKGROUND: Day case total shoulder arthroplasty (TSA) is a novel approach, not widely practiced in Europe. We conducted a retrospective cohort study of patients comparing elective day case and inpatient TSAs in our United Kingdom centre. AIM: To evaluate the efficacy and cost-effectiveness of day case TSA compared to standard inpatient total shoulder arthroplasty. METHODS: All patients undergoing TSA between January 2017 and July 2018 were included. Outcome measures were: Change in abduction and extension 3 mo postoperatively; 30-d postoperative adverse events and re-admissions in day case and inpatient groups. We also conducted an economic evaluation of outpatient arthroplasty. Multivariate linear and logistic regression were used to adjust for demographic and operative covariates. RESULTS: Fifty nine patients were included, 18 d cases and 41 inpatients. There were no adverse events or re-admissions at 30 d postoperatively in either group. There were no significant differences in adjusted flexion (mean difference 16.4, 95%CI: 17.6-50.5, P = 0.337) or abduction (mean difference: 13.2, 95%CI: 18.4-44.9, P = 0.405) postoperatively between groups. Median savings with outpatient arthroplasty were £529 (interquartile range: 247.33-789, P < 0.0001). CONCLUSION: Day case TSA is a safe, effective procedure, with significant cost benefit. Wider use may be warranted in the United Kingdom and beyond, with potential for significant cost savings and improved efficiency.

Periosteal nerve blocks for distal radius and ulna fracture manipulation--the technique and early results.

BACKGROUND: We present a pilot series of patients with distal forearm fractures manipulated following a proximal periosteal nerve block with local anaesthesia. This is a novel technique which can be utilised in adults and children and is described herein. METHODS: With a median of 40 years (range 10-81 years), 42 patients (16 children) with distal radial and ulnar fractures were included. Of these patients, 40 underwent periosteal blocks in the emergency room or fracture clinic; 2 were already inpatients. Fractures were manipulated routinely and immobilised with plaster. Mobile fluoroscopy was not used for patients in the emergency department or fracture clinic. RESULTS: Of the 42 patients, 40 patients (95%) had successful fracture manipulation and did not require subsequent treatment. Two patients (5%) needed subsequent surgery, one for K-wire stabilisation of their fracture and the second for volar plate fixation. The procedure was described as painless in 35 (83%) patients (visual analogue scale/VAS score 0), with 6 (14%) suffering minimal pain (VAS 1-3). In the 12-16-year age group, 15 patients (94%) described the manipulation as painless; 1 patient described the procedure as minimally painful. No additional analgesia of any kind was given. There were no direct complications from any of the periosteal nerve blocks. CONCLUSIONS: Local anaesthetic periosteal nerve blocks injected proximally to the fracture sites are a simple and yet very effective new technique which provide good/excellent analgesia and facilitate the reduction of distal radial and ulnar fractures.
