Modern cemented Furlong hemiarthroplasty: Are dislocations rates better?

BACKGROUND

Dislocation following hip hemiarthroplasty is a major complication with increased mortality and morbidity. Data looking at dislocation following contemporary bipolar stems are lacking in literature.

METHODS

Retrospective review of our prospective national hip fracture database over a two-year period. Group 1 comprised of consecutive patients receiving bipolar Furlong prosthesis (N222) while Group 2 was made up of a historical cohort (uncemented; N254). Clinical and radiological records were reviewed to determine dislocation rates, causes and associative factors of dislocations. Data were analysed using SPSS.

RESULTS

Following 476 hemiarthroplasties performed during the study period, 12 (2.5%) dislocations were reported (eight in Group 1; four in Group 2). There was no significant difference in dislocation rates (3.6% vs 1.6%) between groups (p = 0.159). Subgroup analysis of Group 1 demonstrated a significant difference in dislocations with Furlong cemented (6%) as compared with Furlong uncemented (0%) hemiarthroplasties (p = 0.024). Following dislocation, death rates increased to 8.3% from 1.7% in both groups.

CONCLUSION

There is a statistically significant increase in dislocation rate following use of cemented Furlong prosthesis when compared to similar uncemented prosthesis at the same treatment period. However, when compared to traditional uncemented prosthesis, there is no difference in dislocation rates.

Consenting patients for elective procedures during the pandemic: Are we consenting for risk of nosocomial COVID-19 infection

Introduction: Nosocomial COVID-19 increases morbidity and mortality in patients undergoing surgical procedures. This study assesses the consenting process in patients admitted for surgical procedures with regard to risks of contracting nosocomial COVID-19 infection during the three lockdown periods in the United Kingdom.Methods: Retrospective review of consecutive surgical patients admitted to our tertiary referral centre for surgical procedures during the lockdown periods in the United Kingdom. Data from our hospital's electronic theatre database cross-referenced with the online surgical operative, admission and discharge records were reviewed by three independent reviewers.Discussion: A total of 180 patients (104 males and 76 females) were studied. No patients tested positive perioperatively for COVID-19. The first lockdown had a significantly larger proportion of consultants consenting (P < 0.001). Surgeons consented patients for risk of COVID-19 infection in 34.4% of cases, COVID-19-related illness in 33.9%, inpatient Intensive Care Unit (ITU) admission secondary to COVID-19 infection and risk of death due to COVID-19 in 0.0% and risk of death secondary to inpatient COVID infection in 1.1%.Conclusion: As surgical activity continues and COVID-19 persists, surgeons should be vigilant and ensure proper documentation for consent regarding COVID-19-related complications in line with the Royal College of Surgeons of England guidelines.

Patient evaluation of outpatient venous thromboembolism prophylaxis service following lower limb injuries using a developed validated questionnaire

This paper explores patients' perceptions of a new service and protocol for managing outpatient venous thromboembolism (VTE) prophylaxis, using either subcutaneous Dalteparin or oral off-license Dabigatran in patients with lower limb injury requiring immobilisation. Establishing a patient's perspective is part of good practice as, when this is positive, it aids patient compliance and protocol dissemination. A questionnaire consisting of fifty questions was given at random to one hundred patients over a six month period when they attended the trauma clinic. Each question was scored on a five point Likert scale (1 = poor, 5 = excellent) by the patient. The internal consistency of the questionnaire (Cronbach's alpha reliability coefficient) was more than 0.9 in all domains. Qualitative analysis was done for open-ended questions. One hundred respondents completed the questionnaire, two were void due to significant amounts of incomplete data. The gender split was 54 females, 43 males, and one did not answer the question. The average age was 43 (range 18-72). Sixty seven respondents were first-time attenders, 22 were follow-up patients and nine did not complete this section. The overall average score was 4.26 (range 1-5), with 90% of the patients recommending the service. The overall patient satisfaction for a VTE prophylaxis service is high although there is room for improvement as demonstrated by the range of the scores.

Quality of operation notes in orthopaedic hip arthroplasty surgery: are we complying with British Orthopaedic Association's guide to good practice?

This retrospective audit evaluates the compliance of our operation notes with the British Orthopaedic Society Primary Hip Arthroplasty 'A guide to good practice' using a 24-data point question (BOA 2006). Ninety-nine notes reviewed, of which 94% had patient identifiers, the surgical team was documented in 92.5%, post-operative instruction in 97%, and prosthesis stability in 97% of cases. Despite high standards, we did not achieve the 100% gold standard. We suggest that increased awareness of the 24-point BOA guideline via education and proformas would help to ensure better practice

The cost of outpatient venous thromboembolism prophylaxis following lower limb injuries

This paper reports the cost of outpatient venous thromboembolism (VTE) prophylaxis following 388 injuries of the lower limb requiring immobilisation in our institution, from a total of 7408 new patients presenting between May and November 2011. Prophylaxis was by either self-administered subcutaneous dalteparin (n = 128) or oral dabigatran (n = 260). The mean duration of prophylaxis per patient was 46 days (6 to 168). The total cost (pay and non-pay) for prophylaxis with dalteparin was £107.54 and with dabigatran was £143.99. However, five patients in the dalteparin group required nurse administration (£23 per home visit), increasing the cost of dalteparin to £1142.54 per patient. The annual cost of VTE prophylaxis in a busy trauma clinic treating 12 700 new patients (2010/11), would be £92 526.33 in the context of an income for trauma of £1.82 million, which represents 5.3% of the outpatient tariff. Outpatient prophylaxis in a busy trauma clinic is achievable and affordable in the context of the clinical and financial risks involved.

Routine repeat radiographic examination post fracture fixation: is it necessary?

In spite of the widespread availability of image intensifier for fracture fixation and storage of images on a radiological computer system, routine check radiography is still a common practice. This is even so in situations with no clear indications such as fall or increasing patients' discomfort.
