Aims

Occult (clinical) injuries represent 15% of all scaphoid fractures, posing significant challenges to the clinician. MRI has been suggested as the gold standard for diagnosis, but remains expensive, time-consuming, and is in high demand. Conventional management with immobilization and serial radiography typically results in multiple follow-up attendances to clinic, radiation exposure, and delays return to work. Suboptimal management can result in significant disability and, frequently, litigation.

Methods

We present a service evaluation report following the introduction of a quality-improvement themed, streamlined, clinical scaphoid pathway. Patients are offered a removable wrist splint with verbal and written instructions to remove it two weeks following injury, for self-assessment. The persistence of pain is the patient’s guide to ‘opt-in’ and to self-refer for a follow-up appointment with a senior emergency physician. On confirmation of ongoing signs of clinical scaphoid injury, an urgent outpatient ‘fast’-wrist protocol MRI scan is ordered, with instructions to maintain wrist immobilization. Patients with positive scan results are referred for specialist orthopaedic assessment via a virtual fracture clinic.

The aims were: (1) assess the influence of COVID-19 on mortality in hip fracture; (2) identify predictors of COVID-19 status, and (3) investigate whether social lockdown influenced the epidemiology of hip fracture.

A multicentre retrospective study was conducted of all patients presenting to six hospitals with hip fracture over a 46-day period (23 days pre-/post-lockdown). Demographics, residence, place of injury, presentation blood tests, Nottingham Hip Fracture Score, time to surgery, operation, ASA grade, anaesthetic, length of stay, COVID-19 status, and 30-day mortality were recorded.

Of 317 patients with hip fracture 27 (8.5%) had a positive COVID-19 test; only 7 (26%) had symptoms on admission. COVID-19-positive patients had significantly lower 30-day survival compared to those without COVID-19 (67% versus 92%, p<0.001). COVID-19 was independently associated with increased 30-day mortality adjusting for: (1) age, sex, residence (HR 2.93, p=0.008); (2) Nottingham Hip Fracture Score (HR 3.52, p=0.001), and (3) ASA (HR 3.45, p=0.004). Platelet count predicted subsequent COVID-19 status; a value <217 ×109/L was 68% specific and sensitive (95% CI 58 to 77, p=0.002). A similar number of patients presented with hip fracture pre-lockdown (n=160) and post-lockdown (n=157); there was no significant difference in demographics, place of injury, Nottingham Hip Fracture Score, time to surgery, ASA, or management.

COVID-19 was independently associated with an increased 30-day mortality in hip fracture. Most patients with COVID-19 lacked suggestive symptoms at presentation. Platelet count was an indicator of risk of COVID-19 infection. These findings have urgent implications for the delivery of hip fracture services.

Aims

The primary aim was to assess the independent influence of coronavirus disease (COVID-19) on 30-day mortality for patients with a hip fracture. The secondary aims were to determine whether: 1) there were clinical predictors of COVID-19 status; and 2) whether social lockdown influenced the incidence and epidemiology of hip fractures.

Methods

A national multicentre retrospective study was conducted of all patients presenting to six trauma centres or units with a hip fracture over a 46-day period (23 days pre- and 23 days post-lockdown). Patient demographics, type of residence, place of injury, presentation blood tests, Nottingham Hip Fracture Score, time to surgery, operation, American Society of Anesthesiologists (ASA) grade, anaesthetic, length of stay, COVID-19 status, and 30-day mortality were recorded.

The best method of managing a fracture of the distal humerus in a frail low-demand patient with osteoporotic bone remains controversial. Total elbow arthroplasty (TEA) has been recommended for patients in whom open reduction and internal fixation (ORIF) is not possible. Conservative methods of treatment, including the ‘bag of bones’ technique (acceptance of displacement of the bony fragments and early mobilisation), are now rarely considered as they are believed to give a poor functional result.

We reviewed 40 elderly and low-demand patients (aged 50 to 93 years, 72% women) with a fracture of the distal humerus who had been treated conservatively at our hospital between March 2008 and December 2013, and assessed their short- and medium-term functional outcome.

In the short-term, the mean Broberg and Morrey score improved from 42 points (poor; 23 to 80) at six weeks after injury to 67 points (fair; 40 to 88) by three months.

In the medium-term, surviving patients (n = 20) had a mean Oxford elbow score of 30 points (7 to 48) at four years and a mean Disabilities of the Arm, Shoulder and Hand score of 38 points (0 to 75): 95% reported a functional range of elbow flexion. The cumulative rate of fracture union at one year was 53%. The mortality at five years approached 40%.

Conservative management of a fracture of the distal humerus in a low-demand patient only gives a modest functional result, but avoids the substantial surgical risks associated with primary ORIF or TEA.

Fractures of the tibial shaft are common injuries, but there are no long-term outcome data in the era of increased surgical management. The aim of this prospective study was to assess the clinical and functional outcome of this injury at 12 to 22 years. Secondary aims were to determine the short- and long-term mortality, and if there were any predictors of clinical or functional outcome or mortality. From a prospective trauma database of 1502 tibial shaft fractures in 1474 consecutive adult patients, we identified a cohort of 1431 tibial diaphyseal fractures in 1403 patients, who fitted our inclusion criteria. There were 1024 men, and mean age at injury was 40.6 years. Fractures were classified according to the AO system, and open fractures graded after Gustilo and Anderson. Requirement of fasciotomy, time to fracture union, complications, incidence of knee and ankle pain at long-term follow-up, changes in employment and the patients’ social deprivation status were recorded. Function was assessed at 12 to 22 years post-injury using the Short Musculoskeletal Function Assessment and short form-12 questionnaires. Long-term functional outcome data was available for 568 of the surviving patients, 389 were deceased and 346 were lost to follow-up. Most fractures (90.7%, n = 1363) united without further intervention. Fasciotomies were performed in 11.5% of patients; this did not correlate with poorer functional outcome in the long term. Social deprivation was associated with a higher incidence of injury but had no impact on long-term function. The one-year mortality in those over 75 years of age was 29 (42%). At long-term follow-up, pain and function scores were good. However, 147 (26%) reported ongoing knee pain, 62 (10%) reported ankle pain and 97 (17%) reported both. Such joint pain correlated with poorer functional outcome.

The aim was to perform a cost-utility analysis of total joint replacement in the current environment.

Arthritis is a disabling condition that leads to long-term deterioration in quality of life. Total joint replacement, despite being one of the greatest advances in medicine in the modern era, has come under recent scrutiny. The National Health Service (NHS) has competing demands and resource allocation is challenging in times of economic restraint.

Patients undergoing total hip (n=348) and knee arthroplasty (n=323), from January to July 2010, were entered into a prospective arthroplasty database. A health utility score was derived from the Euroqol (EQ-5D) score preoperatively, and at one year, and was combined with individual life expectancy to derive the Quality-Adujusted-Life-Years (QALYs) gained. Predicted need for revision surgery was Incorporated in the model. The 2011–12 Scottish Tariff was used. Two-way analysis of variance was used to compare QALYs gained between procedures, while controlling for baseline differences.

The number of QALYs gained was higher in THR versus TKR (6.53 vs 4.04 years, p<0.001). The cost per QALY for THR was £1371 (95% CI £1194 to £1614) compared with £2101 (£1762 to £2620) for TKR. Predictors of an increase in QALYs gained were poorer health prior to surgery (p<0.001) and younger age (p<0.001). General health (EQ-5D VAS) showed greater improvement in THR versus TKR (p<0.001).

This study provides up to date cost-effectiveness data for total joint replacement. THR and TKR are both extremely clinically and cost-effective interventions, with costs that compare favourably with other medical interventions (e.g. laparoscopic hernia repair vs open: £55,548 per QALY; CHD primary prevention with statins: £21,000).

Clostridium difficile is associated with a range of gastrointestinal disorders ranging from diarrhoea to toxic megacolon. Alteration of the normal gut flora by antibiotics is a key predisposing factor. Although antibiotic prophylaxis is routinely administered during joint replacement surgery, there has been controversy about both type and duration of prophylaxis. The primary aim of this study was to determine the incidence of C. diff associated disease (CDAD) following hip and knee replacement and to investigate potential risk factors.

A laboratory database was interrogated to identify patients developing CDAD after hip or knee replacement from January 2006 to December 2008. A database of arthroplasty patients was used to identify a control group of patients without CDAD to compare the effects of prescription of antibiotics for reasons other prophylaxis of deep infection, comorbidity and the use of gastroprotective agents.

Eight patients developed CDAD. There were 1.7 cases of CDAD per 1000 joint replacements. Patients developing CDAD were more likely to have been prescribed additional antibiotics (p=0.047). There were no differences in the use of gastroprotective agents (p=0.703). A trial of a new prophylaxis regime would require 43,198 patients in each arm to show a reduction to 1 case per 1000 procedures.

Cefuroxime based antibiotic prophylaxis is safe in patients undergoing elective joint replacement. Extremely large studies would be required to show marginal clinical benefits of new regimes. One prophylaxis policy will not suit all orthopaedic patient groups or procedures.
