Renal Osteodystrophy is a type of metabolic bone disease characterized by bone mineralization deficiency due to electrolyte and endocrine abnormalities. Patients with chronic kidney disease (CKD) are more likely to experience falls and fractures due to renal osteodystrophy and the high prevalence of risk factors for falls. Treatment involves medical management to resolve the etiology of the underlying renal condition, as well as management (and prevention) of pathological fractures. A 66-year-old female patient, with severe osteoporosis and chronic kidney disease undergoing haemodialysis, has presented with multiple fractures along the years. She was submitted to bilateral proximal femoral nailing as fracture treatment on the left and prophylactically due to pathological bone injury on the right, followed by revision of the left nail with a longer one after varus angulation and fracture distal to the nail extremity. Meanwhile, the patient suffered a pathological fracture of the radial and cubital diaphysis and was submitted to conservative treatment with cast, with consolidation of the fracture. Posteriorly, she re-fractured these bones after a fall and repeated the conservative treatment. Clinical management: There is a

Fracture related infections (FRI) are debilitating complications of musculoskeletal trauma surgery that can result in permanent functional loss or amputation. This study aims to determine risk factors associated with FRI treatment failure, allowing clinicians to optimise them prior to treatment and identify patients at higher risk. A major trauma centre database was retrospectively reviewed over a six-year period. Of the 102 patients identified with a FRI (66 male, 36 female), 29.4% (n=30) had acute infections (onset <6 weeks post-injury), 34.3% (n=35) had an open fracture. Open fractures were classified using Gustilo-Anderson (GA) classification (type 2:n=6, type 3A:n=16, type 3B:n=10, type 3C:n=3). Patients with periprosthetic infections of the hip and knee joint, those without prior fracture fixation, soft tissue infections, diabetic foot ulcers, pressure sore infections, patients who died within one month of injury, <12 months follow-up were excluded. FRI treatment failure was defined as either infection recurrence, non-union, or amputation. Lifestyle, clinical, and intra-operative data were documented via retrospective review of medical records. Factors with a P-value of p<0.05 in univariate analysis were included in a stepwise multivariate logistic regression model. FRI treatment failure was encountered in 35.3% (n=36). The most common FRI site was the femoral shaft (16.7%; n=17), and 15.7% (n=16) presented with signs of systemic sepsis. 20.6% (n=21) had recurrent infection, 9.8% (n=10) had non-union, and 4.9% (n=5) required an amputation. The mean age at injury was 49.71 years old. Regarding cardiovascular risk factors, 37 patients were current smokers (36.3%), 31 patients were diabetics (30.4%), and 32 patients (31.4%) were obese (BMI≥30.0). Average follow-up time was 2.37 (range: 1.04-5.14) years. Risk factors for FRI treatment failure were BMI>30, GA type 3c, and implant retention. Given that FRI treatment in 35.3% (36/102) ended up in failure, clinicians need to take into account the predictive variables analysed in this study, and implement a
Advances in our understanding of skeletal stem cells and their role in bone development and repair, offer the potential to open new frontiers in bone regeneration. However, the ability to harness these cells to replace or restore the function of traumatised or lost skeletal tissue as a consequence of age or disease remains a significant challenge. We have developed protocols for the isolation, expansion and translational application of skeletal cell populations with cues from developmental biology informed by in vitro and ex vivo models as well as, nanoscale architecture and biomimetic niche development informing our skeletal tissue engineering approaches. We demonstrate the importance of biomimetic cues and delivery strategies to directly modulate differentiation of human adult skeletal cells and, central to clinical application, translational studies to examine the efficacy of skeletal stem and cell populations in innovative scaffold compositions for orthopaedics. While a number of challenges remain
Objectives. Aged trauma patients are at high risk for various comorbidities and loss of function following hip fracture. Consequently a
More than half of patients with neck of femur (NOF) fractures report their pain as severe to very severe in the first 24hrs. Opioids remain the most commonly used analgesia and are effective for static pain but not dynamic pain. Opioids provide suboptimal analgesia when patients are in a dynamic transition state and their side-effects are a source of morbidity in these patients. The Fascia Iliaca Compartment Block (FICB) involves infiltration of the fascia iliaca compartment with a large volume of low concentrated local anaesthetic to reduce pain by affecting the femoral and lateral cutaneous nerve of the thigh. The London Quality Standards for Fractured neck of femur services (2013) stated that the FICB should be routinely offered to patients. We performed an audit of patient outcomes following the introduction of the FICB across three centres. We performed a two-cycle audit across two hospitals in 2014/15. The first cycle audited compliance with the NICE guidance in the management and documentation of pain and AMTS (Abbreviated Mental Test Scores) in patients. The second cycle was conducted following the integration of the FICB into the multidisciplinary NOF fracture protocol across three hospital sites. Data was collected on numeric pain scores, pre and post-op AMTS and opioid requirements. There were 40 patients audited with 20 in the first cycle prior to the introduction of the FICB and 20 following this. In the second cycle, there was a statistically significant improvement (p<0.001) in the difference between the pre and post-op AMTS. The preliminary findings in this audit support the use of the FICB adjunct to analgesia in the pre-operative management of NOF fracture patients. The FICB is a safe procedure and the organisational learning of this procedure through a

Primary bony tumours of the elbow account for approximately 1% of all osseous tumours. The delayed diagnosis is commonly reported in the literature as a result of lack of clinician familiarity. We present the largest series of primary bone tumours of the elbow in the English literature. We sought to identify characteristics specific to primary elbow tumours and compare these to the current literature. We discuss cases of misdiagnosis and reasons for any delay in diagnosis. The authors also recommend a collaborative protocol for the diagnosis and management of these rare tumours. A prospectively collected national database of all bone tumours is maintained by an independent clerk. The registry and case notes were retrospectively reviewed from January 1954 until June 2013. Eighty cases of primary osseous elbow tumours were studied. Tumours were classified as benign or malignant and then graded according to the Enneking spectrum. There were no benign latent cases in this series. All cases in this series required surgical intervention. These cases presented with persistent rest pain, with or without swelling. The distal humerus was responsible for the majority and most aggressive of cases. The
The diagnosis and treatment of hip disease in young adults has rapidly evolved over the past ten years. Despite the advancements of improved diagnostic skills and refinement of surgical techniques, the psychosocial impact hip disease has on the young adult has not yet been elucidated. This observational study aimed to characterise the functional and psychosocial characteristics of a group of patients from our young hip clinic. 49 patients responded to a postal questionnaire which included the Oswestry Disability Index (ODI) and Hospital Anxiety and Depression Scale (HADS). Median age was 20 years (range 16-38) with a gender ratio of 2:1 (female: male). The most common diagnoses were Perthes' disease and developmental hip dysplasia. More than half of our patients had moderate to severe pain based on the Visual Analogue Scale (VAS) and at least a moderate disability based on the ODI. Thirty-two percent of patients were classified as having borderline to abnormal levels of depression and 49% of patients were classified as having borderline to abnormal levels of anxiety based on the HADS. Comparison of the ODI with the VAS and HADS anxiety and depression subscales showed a significant positive correlation (p<0.05). Multiple regression showed the ODI to be a significant predictor of the HADS anxiety and depression scores (regression coefficient 0.13, 95% confidence interval 0.06 to 0.21, p<0.05). This study highlights the previously unrecognised psychosocial effects of hip disease in the young adult. A questionnaire which includes HADS may be of particular value in screening for depression and anxiety in young people with physical illness. This study also highlights that collaboration with psychologists and other health care providers may be required to achieve a

Patients undergoing total knee arthroplasty (TKA) experience significant post-operative pain. We report the results of a new comprehensive patient care plan to manage peri-operative pain, enable early mobilisation and reduce length of hospital stay in TKA. A prospective audit of 1081 patients undergoing primary TKA during 2008 and 2009 was completed. All patients followed a planned programme including pre-operative patient education, pre-emptive analgesia, spinal/epidural anaesthesia with propofol sedation, intra-articular soft tissue wound infiltration, post-operative high volume intermittent ropivacaine boluses with an intra-articular catheter and early mobilisation. The primary outcome measure was the day of discharge from hospital. Secondary outcomes were verbal rating pain scores on movement, time to first mobilisation, nausea and vomiting scores, urinary catheterisation for retention, need for rescue analgesia, maximum flexion at discharge and six weeks post-operatively, and Oxford score improvement. The median day of discharge to home was post-operative day four. Median pain score on mobilisation was three for first post-operative night, day one and day two. 35% of patients ambulated on the day of surgery and 95% of patients within 24 hours. 79% patients experienced no nausea or vomiting. Catheterisation rate was 6.9%. Rescue analgesia was required in 5% of cases. Median maximum flexion was 85° on discharge and 93° at six weeks post-operatively. Only 6.6% of patients had a reduction in maximum flexion (loss of more than 5°) at six weeks. Median Oxford score had improved from 42 pre-operatively to 27 at six weeks post-operatively. The infection rate was 0.7% and the DVT and PTE rates were 0.6% and 0.5% respectively. This
Introduction. Perioperative antibiotic prophylaxis use in modern orthopaedic procedures is well established. Studies have shown significant reduction in risk of post-operative infections. However, as effectiveness of these antibiotics is dependent on achieving high serum and tissue concentrations that exceed the minimum inhibitory concentrations of infective organisms for operation duration, the timing of prophylaxis is crucial. Although, optimal timing for administering prophylaxis varies in the literature, 30 to 60 minutes prior to skin incision or inflation of tourniquet is considered best standards. Objectives. To audit our practice of timing of administration of perioperative prophylactic antibiotics in trauma and orthopaedic procedures. Methods. A double-centre prospective analysis was conducted over a period of 2 week (trauma) and 2 months (elective). Centre A involved trauma cases where centre B involved elective Total Knee Arthroplasty cases. Patients were excluded if they were already on regular antibiotics or when prophylaxis was not indicated. Prescription charts and anaesthetic charts were reviewed along with electronic theatre database. Results. A total of 109 patients were included (52 elective and 57 trauma). Only 21% of patients received prophylactic antibiotics within 30 to 60 minutes of knife to skin time or inflation of tourniquet. Two third of patients received prophylaxis earlier than recommended with 28% receiving prophylaxis between 5 to 10 minutes and 33% between 15 to 20 minutes prior to knife to skin time or inflation of tourniquet. Conclusions. Our audit highlights an important deviation from standard best practice. To address this problem we recommend a
Background. North America is facing a rising epidemic involving strains of methicillin-resistant Staphylococcus aureus (MRSA) that, instead of being found almost exclusively in hospitals, are community-associated (CA-MRSA). These strains are aggressive, associated with musculoskeletal manifestations including osteomyelitis (OM), and septic arthritis (SA). We aimed to establish novel management algorithms for acute OM and SA in children. We investigated S.aureus susceptibilities to current first-line antimicrobials to determine their local efficacy. Methods. The project was conducted at Nemours Children Hospital in Florida, USA, following approval by the internal review board. A literature review was conducted. An audit of S.aureus antimicrobial sensitivities was completed over three years and compared against national standards. Susceptibilities of clindamycin, trimethoprim/sulfamethoxazole (TMP/SMX) and vancomycin were studied using local resistance ranges. Results. Two algorithms for acute OM and SA management were created adopting a
This review briefly summarises some of the definitive
studies of articular cartilage by microscopic MRI (µMRI) that were
conducted with the highest spatial resolutions. The article has
four major sections. The first section introduces the cartilage
tissue, MRI and µMRI, and the concept of image contrast in MRI.
The second section describes the characteristic profiles of three
relaxation times (T1, T2 and T1ρ)
and self-diffusion in healthy articular cartilage. The third section
discusses several factors that can influence the visualisation of
articular cartilage and the detection of cartilage lesion by MRI
and µMRI. These factors include image resolution, image analysis
strategies, visualisation of the total tissue, topographical variations
of the tissue properties, surface fibril ambiguity, deformation
of the articular cartilage, and cartilage lesion. The final section
justifies the values of multidisciplinary imaging that correlates
MRI with other technical modalities, such as optical imaging. Rather
than an exhaustive review to capture all activities in the literature,
the studies cited in this review are merely illustrative.
