16 to 34% of the population suffer from shoulder pain, the most common cause being rotator cuff tears. NICE guidance recommends using ultrasound scan (USS) or MRI to assess these patients, but does not specify which is preferable. This study assesses the accuracy of USS and MRI in rotator cuff tears in a DGH, to establish the most appropriate imaging modality.

Patients who had at least two of shoulder ultrasound, MRI or arthroscopy within a seven month period (n=55) were included in this retrospective study. Sensitivity, Specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) were calculated using arthroscopy as the true result, and kappa coefficients calculated for each pairing.

59 comparisons were made in total. Sensitivity for MRI in full supraspinatus tears was 0.83, and for USS 0.75. Specificity for MRI in these tears was 0.75, and for USS 0.83. Values were much lower in other tears, which occurred less frequently. USS and MRI completely agreed with each other 61.3% of the time. Both modalities were only completely accurate 50% of the time. Kappa coefficient between arthroscopy and MRI for supraspinatus tears was 0.658, and for USS was 0.615.

There was no statistical difference between MRI and USS sensitivity or specificity (p=1), suggesting that one modality cannot be recommended over the other for full supraspinatus tears. They also do not tend to corroborate one another, suggesting that there is no benefit from doing both scans. Further research is needed to see how both modalities can be improved to increase their accuracy.

Waiting time to access medical care in Canada is 20% more than the international average. Delay in instituting care in trauma patients has been shown to correlate with higher complication rates and an increase in mortality. About 11% of all fractures occur in the femur and are usually treated operatively. Delay to operative treatment is a source of distress to patients and a major factor for poor outcome. Knowledge gaps exist for statistics on operative delay to fixation of femur fractures and the influence on complications and cost of treatment.

This study describes (1) the effect of delay to fixation of femur fractures on complications and on the overall cost of care in hospitals in Quebec Province of Canada; and (2) proposes a time frame within which femur fractures should be operated on to minimize the risk of complications and reduce treatment cost.

6,520 adult patients operated for closed femoral fractures between July 1993 and December 2002 were reviewed. Data was accessed from (a) the Quebec Trauma Registry, (b) the hospitalised patients’ database, Maintenance et exploitation des données pour l’étude de la clientèle hospitalière (MED-ECHO) and (c) the medical insurance claims databases, Régie de l’assurance maladie Québec (RAMQ). Excluded were poly-trauma, open fractures, pathological fractures and delayed diagnoses beyond a week. Data was analysed using the SPSS software version 17.0. Cost analysis was carried out using parametric techniques (Student’s t-test and the generalized longitudinal model).

Mean operative delay for femoral fractures was 26.3 hours. Delay was associated with increased complications, ICU stay, length of stay (LOS), hospitalization costs and out-patient follow-up treatment costs. There was a progressive increase in these adverse events which was quite significant after the first 48 hours. ISS >15 predisposed to prolonged ICU stay, LOS and increased cost of treatment. All femur fractures appeared to have a predilection for over-65-year-olds and women.

The major cost drivers of operative femur fracture treatment were ISS>15, operative delay ≥48 hours, occurrence of complications, and re-operations. Minimizing operative delay in femur fractures will not only mitigate patient suffering, but also reduce treatment and follow-up costs.

‘Getting It Right First Time’ guidance recommends the universal use of cemented prostheses in patients aged over 65 within the UK. This cut off has since been raised to 70. The report claims that the increased cost of uncemented technology is not justifiable in terms of patient outcomes. Our aim was to evaluate any disparity between patients across these age thresholds, in terms of functional outcomes, complication and costs following elective uncemented THR.

We utilised a single surgeon prospectively updated database, to compare functional outcome of patients aged over and under 65 and again at 70 following elective uncemented THR. We measured functional outcome using Oxford Hip Score (OHS). Patients were followed routinely for up to 2 years and subsequently up to 6 years.

Patient ages ranged from 23–89. Over 97% of patients reported an improvement in hip function, with an average increase of 24.1 in OHS. There was no statistical significance between patient age and functional hip outcome, p=0.108 with a cut off at 65 and p=0229 at 70. 1.1% of under 65s required revision surgery, compared to 2.3% of over 65s. 1.4% of patients under 70 required revision surgery, compared to 2.5% in those above. The most common reason for revision surgery was debridement, antibiotics and implant retention. Patients under 65 had a 1.4% chance of experiencing a fracture or dislocation, compared to 2.5% of patients over 65. 2.0% of patients under 70 experienced a fracture or dislocation, in comparison to 2.2% in those over 70. There was 1 recorded mortality, a patient aged over 70. Cost analysis is challenging accounting for all variables between techniques. Cementing invariably requires additional operating time and diminished theatre efficiency, with direct cost estimated at £364 in theatre running fees per case.

Within the series, uncemented THRs was found to be a safe and efficacious procedure irrespective of age. Functional hip outcome was not correlated to patient age, conflicting with GIRFT recommendations. The extra duration of cemented surgery may equilibrate the financial disparity of uncemented practice.
