Surgeons want to counsel their patients accurately about the risks of rare complications. This is difficult for venous thromboembolism (VTE), as most studies report rates of asymptomatic disease. We calculated the rate of confirmed, symptomatic deep vein thrombosis (DVT) and pulmonary embolism (PE) after elective lower limb surgery in our hospital.

We scrutinised referrals for venous Doppler ultrasound and computed tomography pulmonary angiography, identifying all cases of DVT or PE over an 18 month period. These patients were cross-referenced with our elective orthopaedic database and Healthcare Resource Group coding data.

Out of 1071 total hip replacements, there were three DVTs and two PEs, giving an incidence of 0.28% for DVT and 0.19% for PE. Out of 1351 total knee replacements, there were four DVTs and three PEs (incidence 0.29% and 0.22% respectively). Out of 1988 non-arthroplasty hip and knee procedures, there were no DVTs and two PEs (incidence 0.1%). For 1763 elective surgical foot procedures, there were five DVTs (incidence 0.28%), and no PEs.

Currently, Rivaroxaban is offered to patients undergoing hip and knee replacement surgery, but other patients do not receive anticoagulants routinely. Our low incidence of VTE supports this policy and is reassuring for surgeons.

There is increasing focus on publishing comparable data for individual hospitals and surgeons. The Dr Foster website is one portal for accessing such information, and uses hospital episode statistics sent to the Department of Health. For 2008–2011 our Trust was labelled as a statistical outlier with high one year revision rates for total knee replacement; relative risk was 2.53. We examined the accuracy of this information.

According to Dr Foster's data, out of 1517 primary total knee replacements performed between April 2008 and March 2011, fifty-five were revised within one year (29 female: 26 male). This gave a revision rate of 3.6% compared to a 1.4% national average. We reviewed patient records for those labelled as revisions.

Of these cases, only one was a revision total knee replacement within one year. Forty-four had a manipulation under anaesthesia for stiffness and the remaining cases had alternative operations such as arthroscopic washout.

For our Trust, therefore, the data is inaccurate, and a patient relying on such data would be misled. Either Trusts should work with Dr Foster to improve accurate coding of data, or they should keep ownership of their data, and publish accurate figures of their own.

Since NICE issued guidance on preventing venous thromboembolism (VTE), the use of chemoprophylaxis has increased dramatically in trauma and orthopaedics. However, enthusiasm is tempered by a lack of data regarding the true incidence of VTE in everyday practice. We investigated the epidemiology of VTE among ambulatory patients with lower limb injuries within our Trust.

We identified all patients who suffered pulmonary embolism (PE) or deep vein thrombosis (DVT) over an 18 month period, and cross-referenced them with our trauma database. All lower limb injuries were included, whether operated or not. Hip fractures routinely receive dalteparin and were excluded.

There were 11,594 new attendances or post-operative attendances in all fracture clinics over 18 months. Of these, 4530 had lower limb injuries and were immobilised. There were 21 DVTs and 7 PEs in these patients, an incidence of 0.43% and 0.14% respectively. Of note, three DVTs were in patients with Achilles tendon rupture.

The incidence of symptomatic VTE is low in a population of ambulant patients with lower limb injuries in casts, without chemical thromboprophylaxis. Prophylaxis for VTE would thus have a large number needed to treat. The costs and complications of chemoprophylaxis should also be considered before it is introduced universally.


Aims

NICE recommends oral anticoagulants after lower limb arthroplasty, as they are thought to lead to better outpatient compliance than injected anticoagulants. Having prescribed self-administered Dalteparin for many years, we began using oral Dabigatran in December 2010. The change afforded an opportunity to compare compliance and acceptability of the two treatments.

Methods

Patients were recruited at discharge and telephoned at 28 days. Left over doses were counted to assess compliance. Side-effects, complications and patient views were also recorded.

Introduction

Minimally Invasive foot surgery remains controversial. Potential benefits include a reduced incidence of wound complications, faster return to employment and normal footwear. There are no studies published regarding the results of minimally invasive dorsal cheilectomy.

Patients and Methods

Thirty eight patients with painful grade I hallux rigidus underwent dorsal cheilectomy between April 2006 and June 2010. Minimally invasive cheilectomy (MIC) was introduced in August 2009. AOFAS scores, satisfaction, return to normal shoes and employment were assessed.

Aims

We investigated the local epidemiology of Developmental Dysplasia of the Hip (DDH), in order to define incidence, identify risk factors, and refine our policy on selective ultrasound screening.

Methods

Data were recorded prospectively on all live births in the Exeter area from January 1998 to December 2008. We compared those treated for DDH with all other children. Crude odds ratios (OR) were calculated to identify potential risk factors. Logistic regression was then used to control for interactions between variables.

The addition of Extended Scope Practitioner (ESP) clinics was proposed to review new Foot and Ankle referrals, to reduce time consultants spend in clinic and free them up for theatre. There would be a cost benefit to the Primary Care Trusts (PCT), a clinic appointment with the consultants cost's around £140 and ESPs around £70.

We prospectively collected data from the ESP clinics for two months in 2009. We looked at the number of patients referred on to the consultants and how many of these needed surgery.

During this period one hundred and forty one patients were booked into ESP clinics, forty three were referred to the consultants, ninety one were managed by the ESPs and seven patients failed to attend. The estimated saving to the PCT during the 2 month period was £6860 which would be £41,160 over a year. Twenty nine of the patients referred to the consultants required surgery giving a 74% conversion rate.

The use of ESPs in Foot and Ankle Clinic reduces the number of new referrals seen by consultants, therefore being cost effective to the PCTs. This also increased the consultant's surgical conversion rate producing a more efficient service.
