Foot and ankle surgery is a rapidly evolving specialty. As the number and complexity of cases increases, the number of complaints, litigation and pay-outs has also risen. We aim to assess any learning points discerned from NHS litigation data to allow us help improve patient care.

All claims made to the NHS Litigation Authority between 2007 and 2012 relating to foot and ankle problems were obtained under the Freedom of Information Act. These were reviewed, coded and split into subgroups to allow analysis.

There were 232 successful litigation cases between 2007 and 2012. The total amount paid out was almost £18.5 million (range £112 to £1.6 million). A significant number of successful cases were due to patients not having full, informed consent.

A large amount of money is spent in the NHS is spent on litigation. The amount of litigation and payout in foot and ankle surgery compares favourably with hip and knee surgery.

Lack of informed consent is an easily reversible problem that should be decreasing but is actually on the rise. In our trust, we advocate the use of consent clinics which provide a robust and patient-centred approach to informed consent in foot and ankle surgery.

Literature has suggested that obese (BMI >30) and morbidly obese (BMI > 35) patients should not be offered surgery as a day case due to increases in complication and readmission rates. At Torbay hospital, patients are routinely offered day case surgery, in a specialist day case unit, regardless of BMI. This is done with minimal complications and enables a higher throughput of patients and at least 75% of surgical procedures to be performed as a day case, as per NHS guidelines.

We present 12 year data of day case knee arthroscopy surgery performed at Torbay hospital. Over 12 years, 3421 knee arthroscopies were performed. 649 were performed on obese patients and 222 on morbidly obese patients. No anaesthetic complications were observed in any of the obese patient groups and readmissions rates (up to 28 days) were 0.8% in the morbidly obese group and 0.9% in the Obese group, compared to 0.9% for patients with BMI <30.

Our data shows that day case surgery can be performed on all patients regardless of BMI and patient obesity. We believe that other units should offer surgery to obese and morbidly obese patients to allow increased efficiency and achievement of NHS day case guidelines.

Treatment for an infected Total Hip replacement (THR) remains controversial with two stage revision surgery traditionally recommended. We describe a series of one stage revisions performed in a District General Hospital to help inform other surgeons and help treatment decisions.

8 patients with a bacteriologically proven infection in their hip underwent single stage revision THR. Cemented Exeter prostheses were used with additional antibiotics added to the cement mixture prior to implantation.

Follow-up ranged from 6 to 36 months (average 16.6 months) and there were no re-infections. No radiological changes consistent with re-infection were noted throughout patient follow-up. One patient suffered a periprosthetic fracture (thought to be secondary to myeloma) 3 months post-surgery and underwent further revision surgery. Post-operative antibiotics were given for a minimum of 6 weeks with 2 patients having a 3 month supply after Microbiology advice.

Single stage revision THR surgery is a viable and useful option for treatment of infected THR's. Re-infection rates are low. Avoiding the traditional second stage surgery is beneficial to both patients and the NHS trust in terms of health and cost outcomes. We will continue to undertake single stage revisions in this trust and advocate its use by other surgeons.

Recent NICE guidelines have suggested abandoning the Thompson hemiarthroplasty (TH) in favour of a ‘proven prosthesis’ such as the Exeter Trauma Stem (ETS). This is controversial because of significant cost implications and limited research assessing outcomes of the ETS. The aim of this study was to assess the treatment of intracapsular neck of femur fractures with the TH.

Between 2002 and 2006 (minimum 5 year follow-up), 431 cemented TH's were performed. Death rate at 1 year and 5 years were 26.0% and 67.7% respectively. Dislocation (1.4%) and infection (0.2%) rates were low and revision rate was 1.2%. Comparison was made to Bipolar hemiarthroplasties over the same period (total 194). These had lower rates of dislocation (0.5%) and infection (0.5%) with a significantly higher (3.6%) revision rate.

We feel that the TH remains the current gold standard treatment for intracapsular fractures, in appropriate patients, due to low complication and revision rates. Modern implants may provide better function or longevity, but there is no evidence in the literature to support abandoning the TH. Surgeons should assess patients and decide on its use, despite NICE guidelines, as it remains a cost effective treatment method, particularly for older, less mobile and cognitively impaired patients.

Introduction

Anatomical reconstruction of the Anterior Cruciate Ligament (ACL) reconstruction has been shown to be desirable and improve patient outcome. The posterior border of the anterior horn of the lateral meniscus (AHLM) is an easily identifiable arthroscopic landmark, which could guide anatomic tibial tunnel position in the sagital plane. The aim of the study was to establish the relationship between the posterior border of AHLM and the centre of the ACL foot print to facilitate anatomical tibial tunnel placement.

Patients using a neutral rotation brace post proximal humerus fracture fixation have improved functional outcome and external rotation of the shoulder compared to patients using a standard polysling.

Patients who have proximal humerus fracture fixation with extramedullary plates and screws have a risk of reduced range of movement especially external rotation. Gerber et al showed that the average external rotation after fixation of proximal humeral fractures was 39 degrees in their patient cohort compared to a normal range of 80–100 degrees. This can lead to reduced function and poor patient related outcomes. Geiger et al showed that in a cohort of 28 patients, poor functional outcome was noted in 39.3% with an average Constant-Murley Score of 57.9.

Current practice is to utilise a polysling holding the shoulder in internal rotation post-shoulder fixation. Patients usually wear the sling for up to 6 weeks. We believe that this increases the risk of adhesion formation with the shoulder in internal rotation in the shoulder joint. Therefore this can cause loss of external rotation in the shoulder joint. We believe that holding the shoulder in a neutral alignment, with a neutral rotation brace post-fixation, will enable an increased rate of external rotation post-operatively thus improving external rotation and functional outcome

There is currently no literature comparing the different slings used post-operatively and we believe that this study would be the first of its kind. It would have a substantial change in the way clinicians manage proximal humeral fractures and will potentially reduce the numbers of re-operations to divide adhesions or perform capsular releases. Secondary benefits include a potential earlier return to full function and work and improved patient satisfaction.

Study proposal: Prospective Randomised Controlled Trial of the neutral rotation brace compared to the standard, currently used, polysling post proximal humerus fracture fixation. No blinding of either participants or clinicians. Three surgeons utilising similar fixation techniques via the deltopectoral approach and using Philos plate fixation (Synthes Ltd.). Standardised post-operative rehabilitation protocol for all patients.

Follow up: clinical review and postal outcomes for 1 year

Primary outcomes: Post operative functional outcome scores (Oxford, DASH, EQL) obtained at 6 weeks, 9 weeks, 3 months and 1 year). These will be compared to scores taken pre-operatively.

Secondary outcomes: Clinical review at 6 weeks, 3 months and 1 year with range of movement measurements. Radiographs also taken at 6 weeks and 3 months to assess union. Patient questionnaire at 1 year (with outcome scores) assessing patient return to work, complications and patient satisfaction

Inclusion criteria: Proximal humeral fractures requiring operative intervention with extramedullary plate fixation (i.e. fractures displaced by 1cm and/or angulated by 45 degrees or more). Age>18.

Exclusion Criteria: Patients having intra-operative findings of complete Pectoralis major rupture or if operative exposure requires complete Pectoralis major tenotomy. (These patients need to be held in internal rotation with a standard polysling to allow healing of the Pectoralis major tendon).

Femoral neck stress fractures (FNSF) are uncommon, representing 3.5% to 8% of all stress fractures in military recruits. The majority of displaced FNSF undergo operative fixation and are at risk of avascular necrosis (AVN) and non union with a 40–100% medical discharge rate. We aimed to review the incidence and outcome of displaced FNSF in Royal Marine Recruits.

Retrospective review identified 6 Royal Marine recruits, aged 17 to 25, who had suffered a displaced FNSF over a 6 and a half year period. Incidence was 0.93 per 1000 recruits.

Patients were treated urgently by operative fixation with a 2 hole dynamic hip screw device, in 3 cases supplemented with an anti-rotation screw. There were no cases of AVN, no surgical complications and no further procedures were required. All united with a mean time to union of 11 months. 50% had a union time greater than 1 year. 2 completed training, 2 are still in rehabilitation and 2 (33%) were discharged before completion of training.

These fractures are slow to unite compared to other fractures at this site or stress fractures elsewhere. With urgent surgical intervention and stable fixation all however went onto successful union with time and all returned to rehabilitation or training with minimal complications. Awareness of the length of time to union has been invaluable in guiding treatment and rehabilitation. It can help avoid the risks of unnecessary secondary interventions for delay to union.

Purpose

Great expense is accumulated in investigation and management, often with poor outcome, of a patient with a painful TKR. We aim to produce guidelines for their investigation and careful, successful management.
