There is a paucity of data available for the use of Total Femoral Arthroplasty (TFA) for joint reconstruction in the non-oncological setting. The aim of this study was to evaluate TFA outcomes with minimum 5-year follow-up.

This was a retrospective database study of TFAs performed at a UK tertiary referral revision arthroplasty unit. Inclusion criteria were patients undergoing TFA for non-oncological indications. We report demographics, indications for TFA, implant survivorship, clinical outcomes, and indications for re-operation.

A total of 39 TFAs were performed in 38 patients between 2015–2018 (median age 68 years, IQR 17, range 46–86), with 5.3 years’ (IQR 1.2, 4.1–18.8) follow-up; 3 patients had died. The most common indication (30/39, 77%) for TFA was periprosthetic joint infection (PJI) or fracture-related infection (FRI); and 23/39 (59%) had a prior periprosthetic fracture (PPF). TFA was performed with dual-mobility or constrained cups in 31/39 (79%) patients. Within the cohort, 12 TFAs (31%) required subsequent revision surgery: infection (7 TFAs, 18%) and instability (5 TFAs, 13%) were the most common indications. 90% of patients were ambulatory post-TFA; 2 patients required disarticulation due to recurrent PJI. While 31/39 (79%) were infection free at last follow-up, the remainder required long-term suppressive antibiotics.

This is the largest series of TFA for non-oncological indications. Though TFA has inherent risks of instability and infection, most patients are ambulant after surgery. Patients should be counselled on the risk of life-long antibiotics, or disarticulation when TFA fails.

Aims

The aim of this study was to determine the stability of a new short femoral stem compared with a conventional femoral stem in patients undergoing cementless total hip arthroplasty (THA), in a prospective randomized controlled trial using radiostereometric analysis (RSA).

Patients and Methods

A total of 53 patients were randomized to receive cementless THA with either a short femoral stem (MiniHip, 26 patients, mean age: 52 years, nine male) or a conventional length femoral stem (MetaFix, 23 patients, mean age: 53 years, 11 male). All patients received the same cementless acetabular component. Two-year follow-up was available on 38 patients. Stability was assessed through migration and dynamically inducible micromotion. Radiographs for RSA were taken postoperatively and at three, six, 12, 18, and 24 months.

Background

Short bone-conserving femoral stem implants were developed to achieve more physiological, proximal bone loading than conventional femoral stems. Concerns have arisen, however, that improved loading may be offset by lower primary stability because of the reduced potential area for bony contact.

Aims

The aim of this study was to determine the primary stability of a novel short femoral stem compared with a conventional femoral stem following cementless total hip arthroplasty (THA), in a prospective, blinded, randomised, controlled trial using radiostereometric analysis.

Endoprosthetic replacement (EPR) is an available option for the management of massive bone loss around failed knee implants. The aim of this study was to determine the results of knee EPRs performed for non-tumour indications. Since 2007, 85 EPRs were performed for in a single tertiary centre by seven surgeons. Mean age at surgery was 73.5 years (range:35–95) with infection as the most common indication (49%), followed by aseptic loosening (18%), complex primary replacement (16%), fracture (15%) and mechanical failure (2%). Mean follow up was 4 years (range:1–9). Functional outcome was determined using the Oxford Knee Score (OKS). At follow-up, 21 patients were deceased and 2 lost to follow-up. Complication rate was 19%. Of the 7 infected cases, 6 were treated with DAIR (debridement, antibiotics, and implant retention) and one underwent above knee amputation. Four of the patients undergoing DAIR were cleared of infection and 2 are on long-term antibiotics. Accounting for implant revision, loss to follow-up and those on long-term antibiotics as failures, 5-year survival was 89% with an average OKS of 25 (SD=10). This mid-term study shows that distal femur EPR is a valuable option for the increasing burden of complex revision knee surgery

Objectives

A possible solution for the management of proximal femoral bone loss is a modular femoral endoprosthesis (EPR). Although the outcome of EPRs in tumour surgery has been well described, the outcome of their use in revision hip surgery has received less attention. The aim of this study was to describe the outcome of using EPR for non-neoplastic indications.

Methods

A retrospective review of 79 patients who underwent 80 EPRs for non-neoplastic indications was performed, including the rates of complication and survival and the mean Oxford Hip Scores (OHS), at a mean of five years post-operatively. The mean age at the time of surgery was 69 years (28 to 93) and the mean number of previous operations on the hip was 2.4 (0 to 17). The most common indications for EPR implantation were periprosthetic joint infection (PJI) (n = 40), periprosthetic fracture (n = 12) and failed osteosynthesis of a proximal femoral fracture or complex trauma (n = 11).

The management of proximal femoral bone loss is a significant challenge in revision hip arthroplasty. A possible solution is the use of a modular proximal femur endoprosthesis (EPR). Although the survivorship and functional outcome of megaprostheses used in tumour surgery has been well described, outcome of EPRs used in revision hip surgery has received less attention. The aim of this study was to determine the 5-year outcome following proximal femur EPR and determine factors that influence it.

This was a retrospective consecutive case series of all EPRs (n=80) performed for non-neoplastic indications, by 6 surgeons, in our tertiary referral centre, between 2005–2014. Patient demographics and relevant clinical details were determined from notes. The most common indications for the use of EPRs included infection (n=40), peri-prosthetic fracture (n=12) and failed osteosynthesis of proximal femoral fractures/complex trauma (n=11). Outcome measures included complication and re-operation rates, implant survival and assessment of functional outcome using the Oxford-Hip-Score (OHS).

The mean age at surgery was 69 years and mean follow-up was 4 (0 – 11) years. The mean number of previous hip operations was 2.4 (range: 0 – 17). Twenty-five patients sustained a complication (31%), the most common being infection (n=9) and dislocation (n=4). By follow-up, further surgery was required in 18 (22%) hips, 9 of which were EPR revisions. 5-yr implant survivorship was 87% (95%CI: 76 – 98%). Mean OHS was 28 (range: 4 – 48). Inferior survival and outcome were seen in EPRs performed for the treatment of infection. Infection eradication was achieved in 34/41 with the index EPR procedure and in 40/41 hips by follow-up.

Limb salvage was achieved in all cases and acceptable complication- and re-operation rates were seen. EPRs for periprosthetic fractures and failed osteosynthesis had best outcome. We recommend the continued use of proximal femur EPR in complex revision surgery.

Objectives

Guidelines for the management of patients with metastatic bone disease (MBD) have been available to the orthopaedic community for more than a decade, with little improvement in service provision to this increasingly large patient group. Improvements in adjuvant and neo-adjuvant treatments have increased both the number and overall survival of patients living with MBD. As a consequence the incidence of complications of MBD presenting to surgeons has increased and is set to increase further. The British Orthopaedic Oncology Society (BOOS) are to publish more revised detailed guidelines on what represents ‘best practice’ in managing patients with MBD. This article is designed to coincide with and publicise new BOOS guidelines and once again champion the cause of patients with MBD.

Methods

A series of short cases highlight common errors frequently being made in managing patients with MBD despite the availability of guidelines.

Introduction

Hip arthroscopy is a relatively new procedure and evidence to support its use remains limited. Well-designed prospective clinical trials with long-term outcomes are required, but study design requires an understanding of current practice. Our aim was to determine temporal trends in the uptake of non-arthroplasty hip surgery in England between 2001 and 2011.

Methods

Using procedure and diagnosis codes, we interrogated the Hospital Episode Statistics (HES) Database for all hip procedures performed between 2001 and 2011, excluding those relating to arthroplasty, tumour or infection. Osteotomy procedures were also excluded.

Segmental excision of long-bone sarcomas can require complex reconstruction, often resulting in the use of prosthetic replacements at a young age.

The use of vascularised free fibula grafting (VFFG) is well established as a reconstruction modality in sarcoma surgery.

Aims

To analyse the experience of two European sarcoma centres and their use of vascularised free fibula grafting as a primary and revision procedure in limb salvage for diaphyseal long-bone defects in sarcoma surgery.

Methods

A retrospective analysis was carried out of 70 consecutive patients undergoing VFFG between 1996 and 2009 under the Oxford Sarcoma Service (Nuffield Orthopaedic Centre) and the Dutch Orthopaedic Tumour Society (Leiden University Hospital). Clinical and radiological assessments were made and functional outcome scores collected.

Aims

Delays to diagnosis and management of soft tissue sarcomas are preventable but still occur. The introduction of a referral proforma to the Thames Valley Cancer Network in 2005 and National guidelines in 2006 aimed to decrease the incidence of partially and inadequately managed soft tissue sarcomas. This study aims to assess referrals for partially or inadequately managed soft tissue sarcomas and their subsequent management.

Methods

A prospective analysis of all patients referred to the Oxford Sarcoma Service following inadvertent excision of a soft tissue sarcoma between January 2010 and August 2011 was carried out. Pre-operative investigation and subsequent secondary managements were recorded. Patients with a diagnosis of dermatofibrosarcoma protuberans were excluded.

Introduction

Since the introduction of 3rd generation Metal-on-Metal-Hip-Resurfacing-Arthroplasty (MoMHRA), thousands of such prostheses have been implanted worldwide in younger patients with end-stage hip osteoarthritis. However, no independent centre has reported their medium-to-long term outcome. The aim of this study is to report the ten year survival and outcome of the Birmingham Hip Resurfacing (BHR), the most commonly used MoMHRA worldwide.

Methods

Since 1999, 648 BHRs were implanted in 555 patients, the majority of which were male (326). The mean age at surgery was 52.1years (range: 17–82), with primary OA as most common indication (85%). Mean follow up was 7.1years (range: 1–11). The Oxford Hip Score (OHS) and UCLA questionnaires were sent to all patients. Implant survival was established, with revision as the end point. Sub-analysis was performed by gender, femoral component size (small: <45mm, standard: 46–52, large: >53mm) and age at surgery (young:<50yrs, old:>50yrs).

Introduction

Tissue diagnosis is essential to direct the definitive management of a suspected soft tissue or bone sarcoma tissue. Knowledge of both the diagnostic yield and accuracy of core needle biopsies is therefore important to give the investigating team information on the likelihood of their initial investigations achieving a diagnosis.

Methods

This is a retrospective study of patients referred to a specialist orthopaedic centre for investigation of a suspected soft tissue or bone sarcoma. Details of all core needle biopsies performed in a 13-month period were obtained from the hospital database. We defined a diagnostic biopsy as either a specific tissue diagnosis or a biopsy that decided the definitive management of the patient, specifically if malignancy was excluded and no further intervention was required, to calculate the diagnostic yield. Diagnostic accuracy was established by comparing histological diagnosis at biopsy to that at final excision.

Introduction

General Practitioners will be confronted with a sarcoma rarely in their working lives. Most will never see a bone sarcoma although most will see at least one soft tissue sarcoma. Guidelines designed to lead to earlier diagnosis of the most common cancers were introduced by NICE in 2000 and were updated in 2005, containing basic guidance on the earlier diagnosis of bone and soft tissue tumours. Referral criteria include: masses greater than 5cm in diameter, masses deep to fascia, masses which are fixed or immobile, masses which are painful, those which are increasing in size and recurrence after previous excision

Methods

We examined 350 General Practitioner referrals over the past 3 years to our service and examined the correlation between the above criteria and the likelihood of malignancy.

Introduction

Primary soft tissue sarcomas of the extremities are uncommon. Many such lesions will present to specialists in other clinics such as specialist Hand or Foot and Ankle clinics. Many are of a small size at presentation and may appear to be alternate, more common pathology.

Methods

We collected data from all those patients with acral soft tissues sarcomas and referred to the Oxford Sarcoma Service, Nuffield Orthopaedic Centre, Oxford over a thirteen year period from 1997 – 2010. Data were collected regarding the primary suspected diagnosis, the final diagnosis, the referral route and whether patients had undergone previous inadvertent excision.

Introduction

A GP may only encounter one sarcoma in their professional career. Early diagnosis and treatment will improve the outcomes of this rare and malignant disease. Guidelines designed to lead to earlier diagnosis of the most common cancers were introduced by NICE in 2000 and were updated in 2005. These advise and assist in the early referral of potential bone and soft tissue sarcoma. Prior to 2000 only ~10% of GP referrals were proven to be malignant.

Methods

In a referral region of ∼3m, we reviewed the referral patterns of suspected sarcoma by General Practitioners since 2005 in an effort to determine whether the published NICE guidelines had influenced an improvement in the diagnosis and management of malignant disease.

Introduction

Our Unit has been treating large volume soft tissue sarcomas involving the sciatic nerve with epineurectomy for over a decade. The aim of this study was to quantify the functional outcome of patients who were known to have sciatic nerve involvement pre-operatively and went on to have nerve preserving surgery utilising a planned marginal excision with epineurectomy.

Methods

20 patients with soft tissue sarcomas involving the sciatic nerve were studied treated between 1997 and 2010. Nineteen underwent surgery with extended epineurectomy of the sciatic nerve and planned marginal excision. All patients underwent staging and follow up at our Sarcoma Clinic with functional assessment and TESS evaluation.
