ABSTRACT
Background Minimising unnecessary expenditure is essential to cope with high demands on the health sector. A set of full blood count, electrolyte, creatinine and urea tests cost £12 in the National Health Service (NHS). Identifying selected patients requiring postoperative blood tests following primary knee and hip arthroplasty will avoid unnecessary tests and help to reduce expenditure. The aim of our study is to propose criteria for requesting postoperative blood tests that are safe and do not miss patients. Materials and methods We prospectively evaluated 126 patients (72 in the total knee replacement (TKR) group and 54 in the total hip replacement (THR) group) who underwent either an elective primary THR or a TKR. The mean patient age was 71 years. Patient demographics as well as in-patient events throughout each patient's hospital stay were recorded. Hospital readmissions were also monitored for up to 90 days postoperatively. Statistical analysis was performed using SPSS Statistics software (IBM Corp., Armonk, NY) with paired t-tests / Wilcox and mixed measures analysis of variance. Binary logistic regression was used to identify predictors of patients requiring a postoperative blood test. Results Analysis of our data identified the following as risk factors for requiring postoperative full blood count tests, including pre-operative Hb of ≤ 110 g/L, cardiac disease, clinical features of anaemia postoperatively and intraoperative blood loss of > 500 mL. The additional risk factors identified for requiring postoperative electrolyte and urea tests are deranged pre-operative electrolytes and clinical signs or symptoms of electrolyte/renal disturbance such as anuria. No patient was readmitted within 90 days of discharge. Conclusion Overall, applying the criteria we have devised would have saved 74 blood tests in the cohort of 126 patients. This provides an odds ratio of 14.0 (95% confidence interval: 1.77-110, p=0.012) of an abnormal result in the patients that would have been tested, compared to those that would not have been tested.
ABSTRACT
Percutaneous scalpel tenotomy is frequently performed as part of congenital talipes equinovarus (CTEV) to correct the equinus deformity. The use of a scalpel is associated with complications such as neurovascular bundle damage and pseudoaneurysms. In the literature, a percutaneous large-bore needle has been found to be a safer alternative to a scalpel for performing tenotomies. The goal of this study was to conduct a systematic review and report a single-center case series on the use of percutaneous needle tenotomy in the treatment of CTEV. A Preferred Reporting Items of Systematic Review and Meta-analysis (PRISMA)-compliant literature search was conducted to identify studies describing the use of a percutaneous needle tenotomy in the treatment of idiopathic CTEV. A retrospective case series of patients with idiopathic CTEV treated with percutaneous needle tenotomy over a seven-year period from a single center were also conducted. The patients' demographics, the location of the clubfoot, and the Pirani score were all recorded. An analysis of descriptive statistics was carried out. Continuous data were expressed as mean and SD, whereas categorical variables were expressed as absolute numbers and percentages (%). The systematic review included eight papers with a total of 1026 feet and a mean age of 10.4 weeks (SD 5.9). There were 47 (0.04%) complications across all studies, with a pooled success rate of 95%. Eleven patients (16 feet) were included in the single-center case study. The patients' initial Pirani score was 4.8 (SD 1.5), with a final score of 0. (SD 0). Four complications occurred in the patient's cohort - one minor bleeding and three recurrences as a result of poor compliance with the post-tenotomy foot abduction brace. In conclusion, the percutaneous Achilles tenotomy of a CTEV foot with a large bore needle is a safe and effective alternative.
ABSTRACT
BACKGROUND: The surgical management of massive rotator cuff tears remains a challenge. It is suggested that, even in a massive tear that appears irreparable, attempting to repair it as much as possible can be helpful in improving functional outcomes. However the results can be short term and variable. The purpose of our study was to determine if human tissue allograft bridged repair of massive irreparable rotator cuff tears to achieve a complete repair produces similar outcomes compared to partial repair alone. METHODS: We prospectively reviewed outcome scores in 13 patients who underwent partial repair alone for massive irreparable rotator cuff tears and compared them to 13 patients who had partial repairs bridged with allograft. Oxford and Constant scores were compared pre-operatively and at a minimum follow-up of 2 years (range 2 years to 5 years). RESULTS: The mean improvement in the Constant score at final follow-up compared to pre-operative scores was 27.7 points in the partial repair group and 42.8 points in the allograft group (p < 0.01). The Oxford Shoulder Score improved mean of 19.3 points in the partial repair group and 29 points in the allograft group (p < 0.02) at 2 years. CONCLUSIONS: Human tissue matrix allograft provides a better outcome for open bridging of irreparable rotator cuff tears than partial repair alone.
ABSTRACT
AIM: Hip arthrography usually requires the injection of iodine based dyes which can cause complications. We wanted to determine the accuracy of using air for hip arthrography. METHOD: A prospective study was undertaken including all adults who had a hip arthrogram. We initially did an air arthrogram and subsequently injected iohexol to see if we were still in the joint. RESULTS: Forty injections were done. Mean age 32 years. There was a 100% success rate with obtaining a positive air arthrogram. CONCLUSION: Air arthrogram of the hip offers a safe, cost free and accurate alternative to iodine based arthrograms.
ABSTRACT
Isolated avulsion fracture of the index finger metacarpal is rare. There have been only a few noted in the English literature. A review of literature shows that these injuries occur as a result of avulsion of the tendon of extensor carpi radialis longus. In our report we present a case of such an avulsion injury where the proximal fragment was pulled about 2 cm down. The patient was treated conservatively with early mobilisation.
