Metal artefact reduction (MAR) MRI is now widely
considered to be the standard for imaging metal-on-metal (MoM) hip
implants. The Medicines and Healthcare Products Regulatory Agency
(MHRA) has recommended cross-sectional imaging for all patients
with symptomatic MoM bearings. This paper describes the natural
history of MoM disease in a 28 mm MoM total hip replacement (THR)
using MAR MRI. Inclusion criteria were patients with MoM THRs who had
not been revised and had at least two serial MAR
Background. Back pain is a common orthopaedic problem which results in hospital admissions in severe cases. The aim of our study was to identify the reasons for back pain admissions and role of further investigations in the treatment of severe back pain. Methods. We collected data prospectively for all admissions between January and March 2011. Demographic details were recorded along with the reasons for admissions, time of admission, further investigations and treatment offered. Results. Total admissions were 850 and 58 (6.8%) had severe back pain.13 patients (22%) had fractures (Group-A); 16 patients (27%) did not require

Introduction. MRI imaging is carried out to identify levels of degenerative disc disease, and in some cases to identify a definite surgical target at which decompression should take place. We wanted to see if repeat

Intra-articular (IA) tumours around the knee are treated with extra-articular (EA) resection, which is associated with poor functional outcomes. We aim to evaluate the accuracy of MRI in predicting IA involvement around the knee. We identified 63 cases of high-grade sarcomas in or around the distal femur that underwent an EA resection from a prospectively maintained database (January 1996 to April 2020). Suspicion of IA disease was noted in 52 cases, six had IA pathological fracture, two had an effusion, two had prior surgical intervention (curettage/IA intervention), and one had an osseous metastasis in the proximal tibia. To ascertain validity, two musculoskeletal radiologists (R1, R2) reviewed the preoperative imaging (MRI) of 63 consecutive cases on two occasions six weeks apart. The radiological criteria for IA disease comprised evidence of tumour extension within the suprapatellar pouch, intercondylar notch, extension along medial/lateral retinaculum, and presence of IA fracture. The radiological predictions were then confirmed with the final histopathology of the resected specimens.Aims

Introduction. Occult hip fractures occur in 3% of cases. Delay in treatment results in significantly increased morbidity and mortality. NICE guidelines recommend cross-sectional imaging within 24 hours and surgery on the day of, or day after, admission. MRI was the standard imaging modality for suspected occult hip fractures in our institution, but since January 2013, we have switched to multi-detector CT (MDCT) scan. Our aims were to investigate whether MDCT has improved the times to diagnosis and surgery; and whether it resulted in missed hip fractures. Patients/Materials & Methods. Retrospective review of a consecutive series of patients between 01/01/2013 and 31/08/2014 who had MDCT scan for suspected occult hip fracture. Missed fracture was defined as a patient re-presenting with hip fracture within six weeks of a negative scan. A comparative group of consecutive
Objective: To determine whether extended scope physiotherapists (ESP’s) in spinal clinics are able to accurately assess and diagnose patient pathology as verified by MRI findings. Methods: This is a prospective study of 318 new spinal outpatients assessed and examined by one of two spinal ESP’s. 76 patients (24%) were referred for an

Introduction: The possibility of occult hip fracture in older patients after a fall is a common problem. The value of various clinical signs to determine which patients require further investigation has not been reported. Methodology: MRI register was hand searched to identify all patients who had
The aim of this study was to determine the accuracy of Magnetic Resonance Imaging (MRI) scanning compared to arthroscopic findings in patients presenting with chronic ankle pain and/or instability. We reviewed all patients who underwent arthroscopy of the ankle between December 2005 to July 2008 in our institution. A total of 105 patients underwent arthroscopy for chronic ankle pain and/or instability. Twenty-four patients underwent MRI prior to the procedure. We compared the MRI findings with arthroscopic findings. We specifically examined for the anterior talofibular ligament (ATFL), calcaneofibular cigament (CFL) and osteochondral lesions(OCD). Arthroscopic findings were considered as a gold standard. There were 12 female and 12 male patients with an average age 39 years (11–65). The time interval between the
