RESUMO
The ankle joint is well known to show early involvement in severe haemophilia. We describe a novel operative technique developed by the senior author. This combines a medial approach to the ankle, medial malleolar osteotomy, bone graft and compression with staples. All patients had excellent pain relief and improvement in function with 100% achieving bony union. There was a significant improvement in Mazur ankle scores following ankle fusion (P < 0.01). This surgical technique gives good results which are reproducible in this patient population.

The hip is considered to be one of the main load bearing joints of the body. In the haemophilic patient joint bleeds can be catastrophic, leading to long-term joint degeneration and accompanying arthritis. In this review we explore the mechanisms of joint destruction, with particular consideration of the anatomy of the hip and how it may influence disease progression. We also review current strategies for treatment including hip replacement in the haemophilic patient and describe our experiences as a unit. Finally we evaluate future prospects in the management of hip disease in haemophilia.

UNLABELLED: The ageing population and an increase in both the incidence and prevalence of cancer pose a healthcare challenge, some of which is borne by the orthopaedic community in the form of osteoporotic fractures and metastatic bone disease. In recent years there has been an increasing understanding of the pathways involved in bone metabolism relevant to osteoporosis and metastases in bone. Newer therapies may aid the management of these problems. One group of drugs, the antibody mediated anti-resorptive therapies (AMARTs) use antibodies to block bone resorption pathways. This review seeks to present a synopsis of the guidelines, pharmacology and potential pathophysiology of AMARTs and other new anti-resorptive drugs. We evaluate the literature relating to AMARTs and new anti-resorptives with special attention on those approved for use in clinical practice. Denosumab, a monoclonal antibody against Receptor Activator for Nuclear Factor Kappa-B Ligand. It is the first AMART approved by the National Institute for Health and Clinical Excellence and the US Food and Drug Administration. Other novel anti-resorptives awaiting approval for clinical use include Odanacatib. Denosumab is indicated for the treatment of osteoporosis and prevention of the complications of bone metastases. Recent evidence suggests, however, that denosumab may have an adverse event profile similar to bisphosphonates, including atypical femoral fractures. It is, therefore, essential that orthopaedic surgeons are conversant with these medications and their safe usage. TAKE HOME MESSAGE: Denosumab has important orthopaedic indications and has been shown to significantly reduce patient morbidity in osteoporosis and metastatic bone disease.

We have used the Bio-Medicus centrifugal flow pump for vena cava shunting during surgical resection of renal cell carcinoma with extension of the tumor into the inferior vena cava. The active shunt can provide optimal blood return to the heart to promote hemodynamic stability, help provide an isolated field for resection of the involved kidney and its tumor extension into the vena cava, and avoid use of full-dose heparin to minimize blood loss in this extensive operation.

INTRODUCTION: Routine metalwork removal, in asymptomatic patients, remains a controversial issue. Current literature emphasises the potential hazards of implant removal and the financial implications encountered from these procedures. However, there is little literature guidance and no published research on current practice. AIM: To estimate the current state of practice of orthopaedic surgeons in the United Kingdom regarding implant removal in asymptomatic patients. METHODS: An analysis, by two independent observers, was performed on the postal questionnaire replies of 36% (500 out of 1390), randomly selected UK orthopaedic consultants. RESULTS: Four hundred and seven (81%) replies were received. A total of 345 (69%) were found to be suitable for analysis. The most significant results of our study (I) 92% of orthopaedic surgeons stated that they do not routinely remove metalwork in asymptomatic skeletally mature patients; (II) 60% of trauma surgeons stated that they do routinely remove metalwork in patients aged 16 years and under; (III) 87% of the practicing surgeons indicated that they believe it is reasonable to leave metalwork in for 10 years or more; (IV) only 7% of practicing trauma surgeons who replied to this questionnaire have departmental or unit policy. CONCLUSION: Our results demonstrate that most practicing trauma surgeons do comply with the evidence presented in the little literature available. However, we do believe that a general policy for metalwork removal is essential. Such a policy should include guidelines specific to age groups and level of surgeon who should be performing the removal procedure. Such a document would require further validated studies but would eventually serve to steer surgeons in achieving best practice.

There remains a relative paucity in the literature regarding upper limb manifestations of haemophilic arthropathy. Haemophilia has a wide range of clinical manifestations, often presenting with orthopaedic complications. These arise from multiple haemarthroses which exact a cumulative toll on the fabric of the joints. Although the lower limbs are predominantly affected due to their load-bearing nature, upper limb disease is common. This arises from the mechanical demands on the upper limb as the elbow and shoulder become partially weight bearing on use of walking aids such as elbow crutches.

We report two cases of this rare postoperative condition. Both patients having undergone extensive surgery to their hips, developed increased bone growth in the soft tissue of the hip, accounting for the reduced range of movement, pain and stiffness. Plain x-rays taken confirmed the presence of heterotopic ossification, also known as a variant of myositis ossificans. We review the literature and discuss treatment options of this rare condition in patients with end-stage haemophilic arthropathy.
