Aims

Despite few good-quality studies on the subject, total hip arthroplasty (THA) is increasingly being performed for displaced intracapsular fractures of the neck of femur. We compared outcomes of all patients with displacement of these fractures treated surgically over a ten-year period in one institution.

Methods

A total of 2,721 patients with intracapsular fractures of the femoral neck treated with either a cemented hemiarthroplasty or a THA at a single centre were retrospectively reviewed. The primary outcomes analyzed were readmission for any reason and revision surgery. We secondarily looked at mortality rates.

The aim of this study was determine if the detection of pathology in children with a limp can be optimised by screening with blood tests for raised inflammatory markers.

The entry criteria for the study were children (0–15 years) presenting to our hospital Emergency Department from 2012–2015 with a non-traumatic limp or pseudoparalysis of a limb, and no sign of fracture or malignancy on plain radiographs. ESR and CRP blood tests were performed along with other standard investigations. Children with ESR or CRP over 10 underwent MRI scan of their area of pain or tendernesss, with those under 7 years old having general anaesthetic. MRI provided the diagnosis in cases of osteomyelitis, pyomyositis, fasciitis, cellulitis, discitis, as well as non-infective conditions such as malignancy and fracture not visible on plain radiographs. Where a joint effusion was present, the diagnosis of septic arthritis was made from organisms cultured following surgical drainage, or high white cell count in joint fluid if no organisms were cultured. The study was completed once data from 100 consecutive children was available.

64% of children had an infective cause for their symptoms (osteomyelitis, septic arthritis, pyomyositis, fasciitis, cellulitis or discitis). A further 11% had positive findings on MRI from non-infective causes (juvenile idiopathic arthritis, cancer, or occult fracture). The remaining 25% had either a normal scan, or transient synovitis. ESR was a more sensitive marker than CRP, since ESR was raised in 97% of those with abnormal scans, but CRP in only 70%. There were no complications from any of the GA MRI scans. Conclusion: This shows that MRI imaging of all children with a limp and either raised ESR or CRP is a sensitive method to minimise the chance of missing important pathology in this group, and is not wasteful of MRI resources.

Shoulder pain or loss of normal range of motion is a frequent complaint in the outpatient clinic. Of these presentations, rotator cuff injury is a common cause. This can range from mild, transient inflammation of the tendons, to partial tears of tendons, or even full thickness tears. Disruption of the tendons can occur from forceful forward throwing actions undertaken in some sports, for example baseball pitching, more commonly in the UK however, chronic impingement can lead eventually to a tendon tear-usually seen in an older population. Current methods of investigation of such injuries after clinical history and examination, includes plain film radiography, ultrasonography, magnetic resonance imaging and arthrography. We decided to look at how ultrasound can be used in the district general hospital for investigation of such injuries.

Aims

To determine the accuracy of ultrasound as an investigative tool for clinically suspected rotator cuff tears.

Methods

Seventy-five consecutive ultrasonographic study reports, in patients who subsequently underwent arthroscopic examination, were scrutinised and correlated with surgical findings. From this, sensitivity and specificity of ultrasound at this district general hospital were calculated. In addition, this data was compiled for each of the three Consultant Radiologists in order to assess the operator dependent nature of ultrasound.
