Aim: To demonstrate the benefits of fluoroscopy-guided intra-articular steroid injection in the hip with varying degrees of disease severity, and to investigate the financial aspects of the procedure and impact on waiting time., Materials and Methods: A prospective study was undertaken of patients who underwent fluoroscopic intra-articular steroid injection over the 9-month study period. Comparative analysis of the Oxford hip pain score pre- and 6-8 weeks post-intra-articular injection was performed. Hip radiographs of all patients were categorised as normal, mild, moderate, or severe disease (four categories) based on the modified Kellgren-Lawrence severity scale, and improvement on the Oxford hip pain score on each of these four severity categories were assessed., Results: Within the study cohort of 100 patients, the mean increase in post-procedure hip score of 7.32 points confirms statistically significant benefits of the therapy (p<0.001, 95% confidence interval: 5.55-9.09). There was no significant difference in pre-injection hip score or change in score between the four severity categories (p=0.51). Significant improvement in hip score (p<0.05) was demonstrated in each of the four severity categories 6-8 weeks post-injection. No associated complications were observed., Conclusion: The present study confirms that fluoroscopy-guided intra-articular steroid injection is a highly effective therapeutic measure for hip osteoarthritis across all grades of disease severity with significant cost savings and the potential to reduce waiting times., (Copyright © 2015 The Royal College of Radiologists.

Anterior cruciate ligament (ACL) injuries occur most commonly in individuals between 18 and 29 years of age and are strongly correlated with sporting activity, with female athletes being at higher risk of ACL rupture than their male counterparts. ACL reconstruction is one of the most frequently performed procedures in orthopaedic surgery, having a reported incidence of 85 per 100,000 head of population in the at-risk age group. Subsequent graft failure is most commonly caused by recurrent trauma, followed by tunnel malpositioning, although the choice of graft type does not appear to affect outcome. The Danish ACL registry reported that ACL revisions accounted for 7.5% of all ACL reconstruction surgery performed between 2005 and 2008. Revision of ACL reconstruction is recognized to carry a worse outcome than primary reconstruction. Preoperative imaging has become a crucial part of surgical planning in these patients, with great reliance placed on computed tomography (CT). The radiologist should be able to recognize the types of primary repair and must be able to assess for the complications of primary surgery, such as tunnel malpositioning, tunnel widening, and fixation device failure. Revision is commonly a two-stage procedure with bone grafting of the tunnels prior to the definitive ligament repair. The radiologist should be able to asses for adequate bone graft incorporation. The purpose of this article is to present a review of the use of CT in the management of ACL revision surgery with examples of commonly used fixation devices; complications, such as tunnel widening and tunnel malpositioning; and bone graft incorporation., (Copyright © 2013 The Royal College of Radiologists.

Spondylitis is the most common osseous manifestation of Mycobacterium tuberculosis infection. Although treatable, it continues to cause significant mortality and morbidity. Early diagnosis through familiarity with its imaging characteristics is essential to permit rapid treatment and prevent potential life-limiting consequences. In this review, we demonstrate the key magnetic resonance imaging features of this disease., (Copyright © 2011 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.)
