Introduction

Following recommendations in the NHS Plan, all Trusts in the UK now send copies of correspondence to patients as standard practice. It is not clear whether patients wish to receive such correspondence, nor whether this practices an additional workload on the NHS as patients seek clarification on the medical terminology used in their letters.

Methods

We surveyed 90 consecutive patients in three Consultant Foot & Ankle surgeons' new outpatient clinics at our institution. Sixty patients received a copy of the letter sent to their GP (standard practice) and 30 patients received a letter in plain English addressed to the patient and a copy was sent to the GP (new practice). Patients were sent a cover letter explaining the study a copy of their clinic note and also a questionnaire that asked details about their preferred methods of communication. In addition qualitative interviews with 4 GP Partners were carried out to harbour their opinions.

Introduction. Recent advances in minimally invasive surgery and improved post-operative pain management make it possible to perform major foot/ankle operations as day-case. This could have significant impact on length of stay, saving resources and is in keeping with government policy. However, there are theoretical concerns about complications and low patient satisfaction due to pain. Methods. The survey was developed following review of the literature and was approved for distribution by the BOFAS (British Orthopaedic Foot & Ankle Society) scientific committee. An online survey (19 questions) was sent to UK foot and ankle surgeons via the BOFAS membership list. Major foot/ ankle procedures were defined as surgery that is usually performed as an inpatient in majority of centres and day-case as same day discharge, with day surgery as the intended pathway. Results. A total of 132 surgeons responded, 80% from Acute NHS Trusts. The majority (78%) thought that more procedures could be performed as day-case at their centre. Currently 45% of respondents perform less than 100 day-case surgeries per year for these procedures. Despite post-operative pain and patient satisfaction being theoretical concerns for day-case surgery in this population; these outcomes were only measured by 34% and 10% of respondents respectively. The top perceived barriers to performing more major foot and ankle procedures as day-case were: Lack of physiotherapy input pre/post-operatively (23%), Lack of out of hours support (21%). Conclusions. There is consensus among surgeons to do more major foot/ ankle procedures as day-case. Despite theoretical concerns about post-operative pain and satisfaction this was only measured by a third of those surveyed. Out of hours support and physiotherapy input pre/ post-op were perceived as the main barriers. There is a need to scope the provision of physiotherapy pre/post-operatively and out of hours support at sites where this is a perceived barrier

The rate of surgical site infection after elective foot and ankle surgery is higher than that after other elective orthopaedic procedures. Since December 2005, we have prospectively collected data on the rate of post-operative infection for 1737 patients who have undergone elective foot and ankle surgery. In March 2008, additional infection control policies, focused on surgical and environmental risk factors, were introduced in our department. We saw a 50% reduction in the rate of surgical site infection after the introduction of these measures. We are, however, aware that the observed decrease may not be entirely attributable to these measures alone given the number of factors that predispose to post-operative wound infection.

Introduction. Venous thromboembolism (VTE) represents a major cause of morbidity, mortality and financial burden to the NHS. Acquired risk factors are well documented, including immobilisation, lower limb plaster cast and surgery. NICE guidance on VTE prophylaxis within orthopaedics currently excludes operative ankle fracture fixation (ankle ORIF). Aims. Ascertain the local incidence of VTE; compare our local VTE rates with published data from other institutions; review guidelines, scientific literature and other hospitals policies; formulate a local policy for VTE prophylaxis. Method. Retrospective analysis of records of all patients undergoing ankle ORIF in our hospital over a continuous 5 year period, identifying cases of VTE, individual risk factors and surgical duration. Results. 380 patients underwent ankle ORIF; 3 developed VTE; no mortality. VTE incidence 0.79% (0.26%DVT; 0.53%PE). Operative duration 88 +/− 34mins (mean +/− 1S.D); in those with VTE, duration was 35, 90&85min. There is no statistically significant difference (p=0.18) observed between our local and national VTE incidence rates. Operative duration was not a significant factor in those developing VTE. Additional risk factors were identified in one patient with VTE. Discussion. The incidence of heparin induced thrombocytopenia is 0.5%, its associated mortality 10% (i.e. 1:2000). To prevent one fatal PE in foot & ankle surgery, 10,000 must receive VTE prophylaxis. Therefore, heparin associated mortality exceeds VTE associated mortality in foot & ankle surgery. Conclusion. Our local VTE rates are comparable to national rates. Risk of pharmacological prophylaxis exceeds benefit; therefore routine use not justified. Individual risk should be assessed; higher risk patients may benefit

Aims

To describe outcome reporting variation and trends in non-pharmacological randomized clinical trials (RCTs) of distal tibia and/or ankle fractures.

Methods

Five electronic databases and three clinical trial registries were searched (January 2000 to February 2022). Trials including patients with distal tibia and/or ankle fractures without concomitant injuries were included. One reviewer conducted all searches, screened titles and abstracts, assessed eligibility, and completed data extraction; a random 10% subset were independently assessed and extracted by a second reviewer at each stage. All extracted outcomes were mapped to a modified version of the International Classification of Functioning, Disability and Health framework. The quality of outcome reporting (reproducibility) was assessed.

Diabetes is a poor prognostic indicator after an ankle fracture. Many surgeons avoid operating due to concerns regarding complications. We performed a retrospective analysis of complication rates for acute ankle fractures in diabetics with a control non-diabetic patient treated by all surgeons in our unit and assessed factors for success including long-segment fixation. Patient records were cross-referenced with departmental databases and a review of all ankle fractures managed in our department was conducted from 2012. All patients subjected to a retrospective-review of their follow-up for at least 6-months. Radiographs were assessed of the ankle before and at completion of treatment being reviewed independently (RA & FR). We identified the HB1Ac (diabetic-control) and systematic co-morbidities. Fractures were classified into unimalleolar, bi malleolar and trimalleolar and surgery grouped into standard or long-segment-rigid fixation. Statistical analysis was conducted using absolute/relative risk (RR); numbers needed to treat (NNT) were calculated. We compared a control-group, a diabetic group managed conservatively, and undergoing surgery; comparing the concept of rigid fixation and prolonged imobilisation in isolation or combined. Further sub-analysis conducted assessing diabetic neuropathy, retinopathy and nephropathy. Ethics approval was granted as per our institutional policy by our governance lead. We identified 154 diabetic ankle fractures, seventy-six had conservative-treatment; 78 had operative fixation of which 23 had rigid-long-segment-fixation. The diabetic-groups had a higher risk-relative-risk of complication − 3.2 (P< 0.03) being linked to systematic complications of diabetes e.g. neuropathy 5.8 (P< 0.003); HBA1c 4.6 P< 0.004); and neuropathy or retinopathy 6.2 (P< 0.0003). Relative-risk reduction of complications occurred following surgery with prolonged immobilization (0.86) and rigid-fixation (0.65). The Number-Needed-to-Treat required to see a benefit from rigid fixation was 7. Diabetics have a higher risk for complications, however the risk is not as great as previously reported. We provide evidence of rigid-long-segment-fixation with prolonged-immobilization improving-outcomes

Introduction:. Vitamin D plays an important role in bone turnover. Deficiency (including borderline deficiency, or insufficiency) has a known association with fractures and has been linked to delayed or nonunion of fractures. We therefore routinely test vitamin D in cases of nonunion. Noting a high rate of vitamin D deficiency in this group, we instituted a policy to routinely screen for and treat vitamin D deficiency in both post-operative and pre-operative patients. We hypothesised that, in the post-operative patients, levels would correlate with rates of union. Methods:. We sent serum vitamin D levels on consecutive post-operative patients seen in clinics between January and May 2014. They included those with an arthrodesis of the ankle, triple joint or first MTPJ. Union was deemed to have occurred when the patient was comfortable full weight bearing and radiographs showed trabeculae crossing the fusion site. Nonunions were all confirmed with computed tomography. Results:. Ten patients were treated for nonunion, and had a mean serum vitamin D of 58nmol/L. Fourteen patients (collected over a shorter time period) had confirmed union, with a mean vitamin D of 90nmol/L. This was statistically significant on a one tailed Student's t test (p=0.038). Vitamin D was deficient in five (50%) of nonunions and in three (21%) of unions, giving an odds ratio of 3.67. Conclusions:. Our early results show a significant association of serum vitamin D levels with likelihood of nonunion, and we continue to collect data. There is a high prevalence of vitamin D deficiency in our patient population. This is of concern both for the outcome of their surgery and for their lifetime fracture risk. We recommend either screening for or presumptively treating vitamin D deficiency

Aims

The aim of this study was to investigate whether on-demand removal (ODR) is noninferior to routine removal (RR) of syndesmotic screws regarding functional outcome.

Methods

Adult patients (aged above 17 years) with traumatic syndesmotic injury, surgically treated within 14 days of trauma using one or two syndesmotic screws, were eligible (n = 490) for inclusion in this randomized controlled noninferiority trial. A total of 197 patients were randomized for either ODR (retaining the syndesmotic screw unless there were complaints warranting removal) or RR (screw removed at eight to 12 weeks after syndesmotic fixation), of whom 152 completed the study. The primary outcome was functional outcome at 12 months after screw placement, measured by the Olerud-Molander Ankle Score (OMAS).

Introduction. Fifth metatarsal fracture is a common injury. Current practice supports conservative management, with surgery in the event of non-union. Early fracture clinic review is not perceived to improve patient experience or increased detection of non-union. A new protocol standardises treatment to symptom level and discharges patients from ED with advice but without any routine follow-up arranged. A leaflet advises on management, prognosis and helpline details and there is an open-access policy for those whose symptoms persist to investigate potential non-union. Method. A prospective audit evaluated the protocol, surveying patients at 8-weeks and 6-months post-injury. A minor injuries unit continued to refer to fracture clinic and was the control group. During 6-months 46 acute fractures were recorded in the new protocol(group 1) and 47 in the control(group 2). 1 patient in each group was known to experience non-union. 31 of group 1 and 22 of group 2 responded to at least one survey. Results. Satisfaction with information provided at initial presentation was high for both protocols. 87%(27/31) satisfied in group 1 and 90%(20/22) group 2(p=1.0000). At 8-weeks 82%(19/23) were satisfied with their progress following the new protocol compared to 89%(17/19) in the control(p=0.6729). At 6-months 88%(22/25) were satisfied compared to 76%(13/17) respectively(p=0.4133). The new protocol is not associated with a significant symptoms increase. At 8 weeks 22%(5/23) described their pain severity as >5/10 reducing to 8%(2/25) by 6-months. Compared to 10%(2/19) of the control at 8-weeks and 6%(1/17) at 6-months. Patients rating fracture management overall as ‘good or excellent’ were comparable between both new, 67%(21/31) and traditional, 77%(17/22) protocols(p=0.5441). Conclusion. No significant difference in patient satisfaction and symptom levels between the old and new protocol was found. The new protocol reduces unnecessary patient appointments. This reduces demands on fracture clinic while maintaining a safe, resource efficient service

1737 elective foot and ankle cases were prospectively audited from Dec 2005 to end June 2010. All cases were brought back to a specialist nurse dressing clinic between 10 and 17 days post op. Data was collected at the dressing clinic with a standardised proforma on the type of surgery, the state of the wound and any additional management required. Those patients with a pre-existing infection were excluded. Of the 1737 cases 201 (11.6%) had a minor wound problems such as excessive post op bleeding into the dressings, suture problems, early removal of K wires, delayed wound healing and minor infection. 42 patients required antibiotics (2.4%) 8 patients had a deep wound infection (0.5%) requiring intravenous antibiotics and or further surgery. There were 1185 forefoot procedures 36 of which developed an infection (3%), overall infections of the mid/hindfoot was 6 (1%). Practice has changed as a result of the audit (reviewed annually). We have changed our closure techniques (reducing suture problems). For the past 2 years all of our elective foot and ankle patients now go to an ultra clean ward (Joint Replacement Unit) and we have shown a reduction in infection rates by over 50% since. Our infection rate before the JRU was 3.3% with 0.7% deep infection rate (818 procedures) and after the introduction of the JRU our infection rate has ped to 1.6% superficial and 0.3% deep infection p<.001. This large series prospective study sets a benchmark for infection rates in elective foot and ankle surgery. It also highlights the benefit of a dedicated orthopaedic elective unit with rigorous infection control policy and the need to regularly review our results

Aims

A pilon fracture is a severe ankle joint injury caused by high-energy trauma, typically affecting men of working age. Although relatively uncommon (5% to 7% of all tibial fractures), this injury causes among the worst functional and health outcomes of any skeletal injury, with a high risk of serious complications and long-term disability, and with devastating consequences on patients’ quality of life and financial prospects. Robust evidence to guide treatment is currently lacking. This study aims to evaluate the clinical and cost-effectiveness of two surgical interventions that are most commonly used to treat pilon fractures.

Methods

A randomized controlled trial (RCT) of 334 adult patients diagnosed with a closed type C pilon fracture will be conducted. Internal locking plate fixation will be compared with external frame fixation. The primary outcome and endpoint will be the Disability Rating Index (a patient self-reported assessment of physical disability) at 12 months. This will also be measured at baseline, three, six, and 24 months after randomization. Secondary outcomes include the Olerud and Molander Ankle Score (OMAS), the five-level EuroQol five-dimenison score (EQ-5D-5L), complications (including bone healing), resource use, work impact, and patient treatment preference. The acceptability of the treatments and study design to patients and health care professionals will be explored through qualitative methods.

Introduction. Major ankle and hindfoot surgery has traditionally been performed as an inpatient. Recent advances in minimally invasive surgery and improved post-operative pain management make it possible to contemplate performing major ankle and hindfoot operations as a day-case. This could have a significant impact on length of stay for these major cases, saving resources and in keeping with government policy. In this study, we prospectively audited the outcome of the first cohort of patients undergoing major ankle and hindfoot surgery as a day-case against a series of standards. Methods. Twenty four consecutive patients who underwent ankle or hindfoot surgery between August 2009 and April 2010 were considered for day surgery. Seven patients were deemed not suitable due to co-existing medical conditions or insufficient help at home. This left 17 patients who had ankle or hindfoot surgery as a day case. All patients received an ultrasound-guided regional nerve block and spinal or general anaesthesia. The data was collected on patient demographics, diagnosis, and type of surgical procedure. Patients received the standard follow-up regimen for a particular procedure. Patient satisfaction was assessed using a standard questionnaire which included self-monitoring of post-operative pain at 6, 24 and 48 hrs. In addition, any adverse outcomes were recorded. Results. The average age was 48 (range 23-67) years. There were 7 males and 10 females. The surgical procedures included arthroscopic ankle fusion (5), subtalar fusion (5), talonavicular fusion (1) midfoot fusion with calcaneal osteotomy (1), tibialis posterior reconstruction (3) tendo-achilles reconstruction (1) and arthroscopy and lateral ligament reconstruction (1). 93% patients reported that they were given enough information and advice about their operation as a day case. No patients reported severe pain at 6 hrs. One patient had severe pain at 24 hrs post-op. Four patients (23%) had significant pain at 48 hrs and required strong analgesia. Thirteen (77%) patients stated that they would recommend having this surgery as a day-case if they were having it again whereas four (23%) would prefer staying in overnight. The average length of stay for the patients deemed unsuitable for day surgery was 3.8 (range 1-6) days. Conclusions. Our initial results of performing major ankle and hindfoot procedures as day surgery are encouraging but pain control at 48 hrs still remains an unsolved issue and further optimisation is needed

Introduction. Ottawa ankle rules originally described in 1992 have been shown to improve the pick-up rates of ankle fractures and avoid the need for unnecessary X-rays, thus minimising cost and radiation to the patient. We decided to carry out an audit at our hospital to look at the pick-up rates of ankle fractures and ways to minimise x-rays for the patient both in A&E and in the orthopaedic department. Methods. Ankle x-rays of 1088 trauma patients over a 7 month period from Dec 2009 to June 2010 (inclusive) were reviewed. Patients with ankle fractures were classified according to Weber type, and whether they were treated surgically or non-operatively. Non-operatively treated ankle fractures then formed the main sub-group of our study, looking at the number of follow-up X-rays and the amount of subsequent displacement. The amount of displacement was classified into non-displaced (0 mm), minimally displaced (<2mm) and displaced (>2 mm). Results. 171 patients (out of 1088) were found to have fractured their ankle giving a pick up rate of 16%. (cf a pickup rate of 26% described in literature with implementation of Ottawa rules). The pick up rate fluctuated each month from 31% in December to a meagre 6% fractures in June and this could be due to summertime sports injuries causing less fractures and more sprains. We noted a third more x-rays were ordered in Spring than Winter. There were no changes in junior staff in either the A&E or the orthopaedic department to account for the monthly variations. Conservatively managed fractures were followed up in the fracture clinic (n = 95, 56%) 16% (n = 11) of the conservatively managed patients were classified as Weber A fractures 84% (n=58) as Weber B fractures. No Weber C fractures were conservatively managed. Of the eleven Weber A fractures only one was minimally displaced. Conservatively managed Weber A fractures received an average of 1.36 x-rays on follow up in the Orthopaedic department. Of the Weber B fractures 42 were non-displaced whilst 16 were minimally displaced, and these received an average of 3.23 x-rays on follow up. None of these progressed to displacement > 2mm. Conclusion. Based on our audit, we have introduced a policy to limit the number of follow-up of X-rays for minimally displaced and undisplaced Weber A & B fractures to one. We have also re-emphasized the importance of Ottawa rule implementation in our A&E department

Aims

In the context of tendon degenerative disorders, the need for innovative conservative treatments that can improve the intrinsic healing potential of tendon tissue is progressively increasing. In this study, the role of pulsed electromagnetic fields (PEMFs) in improving the tendon healing process was evaluated in a rat model of collagenase-induced Achilles tendinopathy.

Methods

A total of 68 Sprague Dawley rats received a single injection of type I collagenase in Achilles tendons to induce the tendinopathy and then were daily exposed to PEMFs (1.5 mT and 75 Hz) for up to 14 days - starting 1, 7, or 15 days after the injection - to identify the best treatment option with respect to the phase of the disease. Then, 7 and 14 days of PEMF exposure were compared to identify the most effective protocol.

Aims

This paper documents the epidemiology of adults (aged more than 18 years) with a calcaneal fracture who have been admitted to hospital in England since 2000. Secondary aims were to document whether publication of the United Kingdom Heel Fracture Trial (UK HeFT) influenced the proportion of patients admitted to hospital with a calcaneal fracture who underwent surgical treatment, and to determine whether there has been any recent change in the surgical technique used for these injuries.

Patients and Methods

In England, the Hospital Episode Statistics (HES) data are recorded annually. Between 2000/01 and 2016/17, the number of adults admitted to an English NHS hospital with a calcaneal fracture and whether they underwent surgical treatment was determined.

Aims

In approximately 20% of patients with ankle fractures, there is an concomitant injury to the syndesmosis which requires stabilisation, usually with one or more syndesmotic screws. The aim of this review is to evaluate whether removal of the syndesmotic screw is required in order for the patient to obtain optimal functional recovery.

Materials and Methods

A literature search was conducted in Medline, Embase and the Cochrane Library for articles in which the syndesmotic screw was retained. Articles describing both removal and retaining of syndesmotic screws were included. Excluded were biomechanical studies, studies not providing patient related outcome measures, case reports, studies on skeletally immature patients and reviews. No restrictions regarding year of publication and language were applied.

Clinicians are often asked by patients, “When can I drive again?” after lower limb injury or surgery. This question is difficult to answer in the absence of any guidelines. This review aims to collate the currently available evidence and discuss the factors that influence the decision to allow a patient to return to driving. Medline, Web of Science, Scopus, and EMBASE were searched using the following terms: ‘brake reaction time’, ‘brake response time’, ‘braking force’, ‘brake pedal force’, ‘resume driving’, ‘rate of application of force’, ‘driving after injury’, ‘joint replacement and driving’, and ‘fracture and driving’. Of the relevant literature identified, most studies used the brake reaction time and total brake time as the outcome measures. Varying recovery periods were proposed based on the type and severity of injury or surgery. Surveys of the Driver and Vehicle Licensing Agency, the Police, insurance companies in the United Kingdom and Orthopaedic Surgeons offered a variety of opinions.

There is currently insufficient evidence for any authoritative body to determine fitness to drive. The lack of guidance could result in patients being withheld from driving for longer than is necessary, or returning to driving while still unsafe.

Diagnostic and operative codes are routinely collected for every patient admitted to hospital in the English NHS. Data on post-operative complications following foot and ankle surgery have not previously been available in large numbers. Data on symptomatic venous thromboembolism events and mortality within 90 days were extracted for patients undergoing fixation of an ankle fracture, first metatarsal osteotomy, hindfoot fusions and total ankle replacement over a period of 42 months. For ankle fracture surgery (45 949 patients), the rates of deep-vein thrombosis (DVT), pulmonary embolism and mortality were 0.12%, 0.17% and 0.37%, respectively. For first metatarsal osteotomy (33 626 patients), DVT, pulmonary embolism and mortality rates were 0.01%, 0.02% and 0.04%, and for hindfoot fusions (7033 patients) the rates were 0.03%, 0.11% and 0.11%, respectively. The rate of pulmonary embolism in 1633 total ankle replacement patients was 0.06%, and there were no recorded DVTs and no deaths. Statistical analysis could only identify risk factors for venous thromboembolic events of increasing age and multiple comorbidities following fracture surgery.

Venous thromboembolism following foot and ankle surgery is extremely rare, but this subset of fracture patients is at a higher risk. However, there is no evidence that thromboprophylaxis reduces this risk, and these national data suggest that prophylaxis is not required in most of these patients.

We report an audit of 208 patients with a mean age of 39 years (16 to 65) attending the Orthopaedic Assessment Unit at the Wellington Hospital between January 2006 and December 2007 with an injury of the tendo Achillis requiring immobilisation in a cast. Information on assessment of venous thromboembolism (VTE) risk, prophylactic measures and VTE events for all patients was obtained from the medical records. A VTE risk factor was documented in the records of three (1%) patients. One of the 208 patients received aspirin prophylaxis; none received low molecular weight heparin. In all, 13 patients (6.3%, 95% confidence interval 3.4 to 10.5) developed symptomatic VTE during immobilisation in a cast, including six with a distal deep-vein thrombosis (DVT), four with a proximal DVT, and three with a confirmed pulmonary embolus. This incidence of symptomatic VTE is similar to that reported following elective hip replacement.

We propose that consideration is given to VTE prophylaxis during prolonged immobilisation of the lower limbs in a cast, to ensure that the same level of protection is provided as for patients undergoing elective hip replacement.
