Purpose

In 2010, the new clinical guideline of Osteoporosis Canada for the diagnosis of osteoporosis, clearly indicates that patients with high-risk of fracture are those that have already sustained a fracture (osteoporotic fracture). Until now, only 12% of the 3,400 fractures that we treat each year receive a treatment for osteoporosis. We are validating an evaluation protocol and a multidisciplinary systematic follow-up approach for osteoporosis. Patients are managed by a clinical nurse specialist. We are recruiting 543 patients with an osteoporotic fracture at Hal du Sacré-Coeur de Montréal. We aim to evaluate: 1) the incidence of a second osteoporotic fracture, 2) the initiation of a treatment and determine the compliance and adherence to treatment and 3) the evaluation of CTX-1 and Osteocalcin at Baseline, 6, 12,18 et 24 months (treatment efficacy) and 4) the functional outcome and quality of life post-fracture.

Materials & Methods. Chronic osteomyelitis is a complex and challenging condition the successful treatment of which requires a specialist multidisciplinary approach. Prior to tertiary referral to a specialist Orthoplastic Unit, patients often receive multiple courses of antibiotics, in usually unsuccessful attempts, to eradicate infection. This often results in the development of chronic polymicrobial infection. We reviewed the intra-operative cultures of patients treated in our Orthoplastic unit over a 9-year period from 2012–2021 to determine the spectrum of polymicrobial cultures and the relationship to pre-operative cultures. Results. We reviewed the electronic care records and laboratory results of all patients referred to or directly admitted to our unit with a diagnosis of chronic osteomyelitis between 2012–2021. We checked all culture results, antibiotic sensitivities and prescription for treatment. We also checked for any recurrence of infection within 1 year. 60 patients were treated over the 9-year period. 9 upper and 51 lower limbs. The most common referral sources were from the surgical specialties of Trauma & Orthopaedics and Plastic Surgery (62%) while an equal amount came from the Emergency Department and other inpatient medical teams, each making up 15%. A small cohort (8%) developed the infection while still being followed up post fixation. Aetiology of Infection were post fracture fixation 41 (68%), spontaneous osteomyelitis 10 (17%), soft tissue infection 4 (7%). The remaining 5 patients (8%) had a combination failed arthroplasty, arthrodesis and chronic infection from ring sequestrum. 58 patients (97%) had positive cultures with 26 being polymicrobial. 12 cultures were gram negative (G-ve), 11 G+ve 12, 4 anaerobic and 1 Fungal. In 24 patients (40%) the pre-operative cultures and antibiotic sensitivities did not correspond to the intra-operative cultures and sensitivities. 55 patients (92%) required dual or triple therapy with 8% requiring further debridement and extended therapy. 2 (3%) patients had failed treatment requiring amputation. Conclusions. Chronic osteomyelitis is a complex and challenging condition the successful treatment of which requires early referral to a specialist Orthoplastic unit. Less than half of organisms cultured pre-operatively reflect the causative organisms cultured intra-operatively with 52% of these infections being polymicrobial. After initial treatment, 8% of patients will require a further combination of extended antibiotic therapy and surgery to eradicate infection

Abstract. In the pediatric population, scoliosis is classified into congenital, syndromic, idiopathic, and neuromuscular in aetiology. Syndromic scoliosis represents a wide range of systemic anomalies associated with scoliosis. The primary challenge for a clinician is to think beyond the scoliotic curve, as the underlying pathology is multisystemic. The aim of this review is to identify the systemic anomalies, associated with syndromic scoliosis. MEDLINE, EMBASE, and CINAHL databases were searched, dating from 1990–2020, relevant to the purpose of our study. Keywords used: “scoliosis”+ “syndrome” + “genetic”. Retrospective, prospective studies were included. Case reports that had fewer than 4 patients were not included. Delineating 60 articles, we found a total of 41 syndromes to be associated with scoliosis. Thoracic region was the most common level of scoliosis curve, being noted in 28 syndromes. Mental retardation, seizures, and ataxia were the commonly noticed CNS anomalies. VSD, ASD, and TGA were the anomalies associated with CVS; Hypotonia, rib and vertebral malformations were the most identified neuromuscular anomalies; pulmonary hypoplasia, renal agenesis, and strabismus were other associations. A multidisciplinary approach, involving spinal surgeons, paediatricians, geneticists, anesthesiologists, and allied health professionals, is vital for the best care of patients with syndromic scoliosis. The location of the scoliotic curve reflects the associated anomalies, as thoracic curvature is more closely linked with cardiac anomalies, while lumbosacral curvature is seen to be often linked with genitourinary anomalies. We hope that this article provides a clear overview of the systemic associations in syndromic scoliosis and thus, facilitates and streamlines the management protocol

Abstract. Objectives. This study aims to evaluate the functional outcomes of early weight-bearing in a functional orthosis for conservatively managed, complete AT ruptures. Also we tried to evaluate the patient reported outcome with this form of treatment. Design. In this prospective study, we have analysed data from 41 patients with ultrasound diagnosed compete AT ruptures, with a gap of less than 5 cm. Every patient was treated in a functional weight-bearing orthosis (VACOped®) for 8 weeks with early weight-bearing following a specific treatment protocol, followed by rehabilitation with a trained physiotherapist. Methods. Patients were followed up with foot and ankle trained physiotherapist for at least 1 year post-injury. At final follow up, the followings were measured: calf girth, single-leg heel raise height and repetitions. Furthermore, ATRS score and a patient feedback were taken on this final visit. Result. The mean ATRS score was 82.1, with a re-rupture rate of only 2% as compared to 5% in normal orthosis. The average calf bulk difference was 1.6 cm, the average heel raise height difference was 1.8cm and a heel raise repetition difference of 6. There was a statistically significant correlation between ATRS score and calf muscle girth (p=0.02). However, there was no significant correlation between ATRS and heel raise height or heel raise repetitions. Conclusion. Early weight-bearing in a functional orthosis provides excellent functional outcomes for conservatively managed, complete AT ruptures, and is associated with very low re-rupture rates. A multidisciplinary approach with a guided rehabilitation programme is essential for optimising functional outcome

Introduction. Wide, tumor-like resection for chronic osteomyelitis (COM), a standard practice previously, has been challenged recently with adequate, local debridement. This paper reviews the evolution of surgical debridement for long bone osteomyelitis, and presents the outcome of adequate debridement in a tertiary bone infection unit. Materials & Methods. Retrospective review of records from 2014 to 2020 of patients with long bone osteomyelitis. All records were searched electronically and imaging reviewed. All patients were managed by Multidisciplinary Infection Team protocol. Results. 53 patients (54 bones) with median age of 45.5 years (IQR 31 to 55) and mean follow-up of 29 months (12 – 59) were identified. According to Cierny-Mader classification, ten bones were type I, 39 were type III, and five were type IV; via the BACH classification of long bone osteomyelitis 21 were uncomplicated, 32 were complex, and one had limited options. All patients were treated with single-staged management with one planned second stage stabilization. Seventy-five percent grew positive microbial cultures. Forty-six (85%) cases had resolution of COM after index procedure and 51 (94%) had resolution at last follow up. Four (7%) patients underwent second surgical procedure and six (11%) patients had complications. Conclusions. We report high COM resolution rate through detailed pre operative evaluation and planning with multidisciplinary team approach. We challenge the need for wide tumor-like resection and the need for regenerative procedures in all cases of COM. Adequate debridement and local delivery of high concentration of antibiotic appears to provide comparable outcomes

Aim. The number of operatively treated clavicle fractures has increased over the past decades. Consequently, this has led to an increase in secondary procedures required to treat complications such as fracture-related infection (FRI). The primary objective of this study was to assess the clinical and functional outcome of patients treated for FRI of the clavicle. The secondary objectives were to evaluate the healthcare costs and propose a standardized protocol for the surgical management of this complication. Method. All patients with a clavicle fracture who underwent open reduction and internal fixation (ORIF) between 1 January 2015 and 1 March 2022 were retrospectively evaluated. This study included patients with an FRI who were diagnosed and treated according to the recommendations of a multidisciplinary team at the University Hospitals Leuven, Belgium. Results. We evaluated 626 patients with 630 clavicle fractures who underwent ORIF. In total, 28 patients were diagnosed with an FRI. Of these, eight (29%) underwent definitive implant removal, five (18%) underwent debridement, antimicrobial treatment and implant retention, and fourteen patients (50%) had their implant exchanged in either a single-stage procedure, a two-stage procedure or after multiple revisions. One patient (3.6%) underwent resection of the clavicle. Twelve patients (43%) underwent autologous bone grafting (tricortical iliac crest bone graft (n=6), free vascularized fibular graft (n=5), cancellous bone graft (n=1)) to reconstruct the bone defect. The median follow-up was 32.3 (P. 25. -P. 75. : 23.9–51.1) months. Two patients (7.1%) experienced a recurrence of infection. The functional outcome was satisfactory, with 26 out of 28 patients (93%) having full range of motion. The median healthcare cost was € 11.506 (P. 25. -P. 75. : € 7.953–23.798) per patient. Conclusion. FRI is a serious complication that can occur after the surgical treatment of clavicle fractures. Overall, the outcome of patients treated for FRI of the clavicle is good, when management of this complication is performed by using a multidisciplinary team approach. The median healthcare costs of these patients are up to 3.5 times higher compared to non-infected operatively treated clavicle fractures. Expert opinion considers factors such as the size of the bone defect, the condition of the soft tissue, and patient demand to guide surgical decision making

Aim. Pelvic osteomyelitis following pressure ulceration results in substantial patient morbidity. Previous studies have reported a heterogenous approach to diagnosis and medical management by physicians, suggesting equipoise on key clinical questions. This study hypothesised that the same equipoise exists amongst Orthopaedic surgeons. Method. An 18-question multiple-choice questionnaire was designed through an iterative feedback process until the final version was agreed by all authors. Likert-type scale responses were used with graded responses (e.g., never/fewer than half of patients/around half of patients/more than half of patients/every patient). The online survey was sent to members of the Musculoskeletal Infection Society (MSIS), the European Bone and Joint Infection Society (EBJIS), and the ESCMID Study Group for Implant-Associated Infections (ESGIAI). No incentive for participation was provided. Results. Amongst respondents, 22/41 were based in Europe and 10/41 from the USA. The majority (29/41) had been in clinical practice between 5—24 years. There was a high priority placed on bone biopsy histology, culture-positive bone sampling, and palpable bone without periosteal covering for diagnosis. Multidisciplinary team approach with plastic surgery involvement at the index procedure was advocated. The strongest indications for surgical intervention were source control for sepsis, presence of an abscess/collection, and prevention of local osteomyelitis progression. Physiological/psychological optimisation and control of acute infection were the primary determinants of surgical timing. There was low utilisation of adjunctive surgical therapies. Local/regional primary tissue transfer or secondary healing with/without VAC were the preferred techniques for wound closure. Recurrent osteomyelitis was the most common reason for prolonged antimicrobial therapy. The majority received bedside advice from an infectious disease-specialist but a quarter of respondents preferred telephone advice. Conclusions. Amongst an international cohort of Orthopaedic Surgeons there was a heterogenous diagnostic and therapeutic approach to pressure-related pelvic osteomyelitis

Aim. Calcaneal osteomyelitis is an uncommon and challenging condition. In this systemic review we aim to analyse the concomitant use of bone debridement and soft tissue management for patients diagnosed with calcaneal osteomyelitis. Method. A complete computerised and comprehensive literature search of Pubmed and Cochrane database was undertaken from January 2000 to October 2018. During the review, studies were screened for information about the surgical and antimicrobial treatment, the complications, the reinfection rate and the functional outcome of patients with calcaneal osteomyelitis. Results. Of the 20 studies included, seven (35%) described bone treatment only, six (30%) soft tissue treatment only, five (25%) soft tissue and bone treatment, and two (10%) focused on prognostic factors and differences in outcomes between diabetic and non-diabetic patients. In the studies with bone treatment only, infection recurrence ranged from 0 to 35% and the amputation rate from 0 to 29%. If soft tissue coverage was also needed, both the reinfection rate and amputation rate ranged from 0 to 24%. Studies presenting the functional status showed preservation or even improvement of the preoperative ambulatory status. Conclusions. Calcaneal osteomyelitis is difficult to treat. A multidisciplinary approach involving orthopaedic surgeons, plastic surgeons and infectious disease physicians is necessary for treatment success. Based on the localisation and size of the bone and soft tissue defect, decision for surgical treatment should be made

Aim. The primary aim of multidisciplinary management of diabetic foot disease is limb savage. Difficulty in eradication of infection with systemic antibiotics and obliteration of dead space created by debridement, are two major stumbling blocks in achieving this. Antibiotic loaded bio composites help achieve both these objectives. The aim of this study is to report the early results of antibiotic loaded bio composites in diabetic foot disease. Method. We present early results of 16 patients with diabetic foot disease and osteomyelitis in whom we used antibiotic loaded bio composite (CERAMENT G Bone Support, Lund, Sweden) for local antibiotic delivery and dead space eradication. A multidisciplinary team managed all patients. We performed magnetic resonance and vascular imaging preoperatively and adhered to a strict protocol involving debridement, culture specific systemic antibiotics and dead space obliteration with antibiotic loaded bio composite. The wound was managed with negative pressure wound therapy and all patients were kept non-weight bearing with a plaster back slab or walking boot. Skin cover where required was undertaken by our plastic surgeons. Results. According to the Cierny –Mader Classification 1 patient was type 1, 4 were defined as type 2, 7 were type 3 and 4 were type 4. Seven patients were classed as type B hosts and 9 were type A hosts. At a mean follow up of 38 weeks (26–60) we achieved infection clearance in 14 patients (88%). 10 (63%)wounds healed by secondary intention, 2 had split skin graft, and 1 had primary closure. 2 patients were still on negative pressure wound therapy at final follow-up, one of which has got clearance of infection. One patient is having regular dressings in the community. We had 2 patients who had below knee amputation, one due to significant vascular disease and the other at patient request. Conclusions. A multidisciplinary approach and a strict protocol including augmented debridement and Cerament G injection are effective for treatment of chronic osteomyelitis in diabetic foot disease. The early results with this bio composite antibiotic combination are encouraging

Aim. A number of orthopaedic strategies have been described for limb salvage following periprosethic joint infection (PJI). However, this is often only possible with concomitant soft tissue reconstruction in the form of flap coverage. The purpose of this study was to determine the long-term clinical outcome of patients who underwent pedicled gastrocnemius flap coverage as part of their treatment for knee PJI. Method. We performed a retrospective review of all patients undergoing gastrocnemius muscle transfer with split thickness skin grafting as part of their treatment for knee PJI at a tertiary referral centre between 1994 and 2015. Data recorded included patient characteristics, orthopaedic procedure, microbiology result and antimicrobial management. Outcome measures included flap failure, infection recurrence, amputation, functional outcome (Oxford knee score; OKS) and mortality. Results. In total, 115 consecutive patients (39% female) with a mean age of 74.4 years (range 44–100) were followed up for an average of 5.5 years (range 119 days – 19.7 years). There were no reported cases of flap failure. Gastrocnemius flaps were most commonly performed at the time of the first stage of a two-stage revision (41%), or during debridement and implant retention (DAIR) (27%). 10% were performed at the second stage of a two-stage procedure and 4% were performed during a single stage revision. Of 96 positive deep specimen cultures, 43 (45%) showed mixed growth and 47 (49%) grew coagulase-negative staphylococcus (with or without other microorganisms). The infection recurrence rate was 32%. Limb salvage was achieved in 88% of cases. 12% of patients required life-long suppressive antibiotic therapy. 55 knees were followed up for five years or more, with a survival (not deceased, not amputated) of 64%. 37 knees were followed up for 10 years or more, with a survival of 32%. In living patients who did not have an amputation, the mean OKS was 25.8 (n=36; range 7–47). Conclusion. This study represents the largest series to date of infected knee prostheses treated with gastrocnemius flap coverage. A multidisciplinary approach to complex PJI surgery is recommended, involving infectious disease physicians and the orthoplastic team. We also recommend a low threshold for requesting plastic surgery input. In our experience, this technique is safe, with no flap failure, and has enabled limb salvage for the majority (88%) of patients with infected knee prostheses and insufficient soft tissue envelope

Introduction. Management of open fractures is challenging and requires a multidisciplinary team approach. Gustilo Anderson Type IIIB fractures reportedly have a higher infection rate (up to 52%) and up to 16% amputation rate. This study aims to evaluate outcomes of using Adjuvant Local Antibiotic Hydroxyapatite Bio-Composite in management of Open Gustilo-Anderson IIIB fractures. Materials and Methods. We reviewed a prospective data of 80 patients who presented with Gustilo Anderson Type IIIB Open Fracture to a single ortho-plastic centre. Only patients who were managed with single-stage “Fix and Flap” along with intra-operative Adjuvant Local Antibiotic Bio-Composite were included. Results. Mean follow-up time was 22 months. The mean time from injury until definitive surgery was 7.73 days (1–30 days). Primary union achieved in 88.3% within 32 weeks on average. The delayed union reported in 7.8% of patients, for the bone healing stimulated by injecting the fracture site with Autologous Bone Marrow Aspirate Concentrate. Subsequent follow-up showed signs of successful fracture healing at 60 weeks post-injury. Three patients (3.9%) had non-union. Limb salvage rate was 96.25%, and only 1.25% deep infection rate. Conclusions. Our results highlight that low infection rates, high limb salvage rates and high union rates can be achieved in these complex injuries with a combined OrthoPlastic approach, MDT input, meticulous technique and the use of adjuvant local antibiotic bio-composite. Delay in definitive surgery, gentamicin resistance and smoking were not associated with any increased deep infection or non-union in our series. At 22 months of follow-up, deep infection rate was 1.25%, limbs salvage rate was 96.25%, fracture union rate was 96.1%, and reoperation rate 18.75%

Aim. Free tissue transfer is an important tool in successful reconstruction of chronic osteomyelitis but can be challenging due to extensive scarring. Our unit follows a multidisciplinary approach including excision of osteomyelitis and immediate microvascular soft-tissue reconstruction simultaneously with orthopaedic reconstruction. We aim to evaluate the success of free tissue transfer and disease recurrence in patients with chronic osteomyelitis. Method. This is a retrospective consecutive cohort study between 2010–2015 inclusive by a single microvascular surgeon in a single centre. All patients had one stage excision of osteomyelitis, orthopaedic reconstruction and microvascular soft tissue reconstruction, with a minimum follow-up period of 1 year. Results. The total number of flap was 76 in 73 patients. The mean age was 45 (18–82). 63 (83%) were to cover the tibia. Flaps used were mainly gracilis (75%) and latissumus Dorsi (16%) with fibula, anteriolateral thigh, vastus lateralis and rectus abdominus also used. 40 patients had end to side anastomosis with 36 being end to end. 98% of the venous anastomosis were to the deep venae comitantes. The average flap ischaemic time was 83 minutes and the total operation time was on average 7.7 hours (5–16 hours). Total flap failure occurred in 3 patients (4%) with one additional flap having tip necrosis. All 3 patients who had total flap failure were successfully reconstructed with a 2nd free flap. 8 patients had residual infection that was successfully treated in 6 patient. Conclusions. Chronic osteomyelitis can be treated with simultaneous excision, orthopaedic reconstruction and free soft tissue reconstruction with high level of success (>90% infection-free at one year). Microvascular soft tissue reconstruction in these patients is almost always technically challenging and consequently a range of flaps and anastomotic techniques are required for these long operations. However, despite this, our study shows that free tissue transfer has a flap survival rate of >95%

Hip fractures are estimated to cost the NHS over £2 billion per year and, with an ageing society, this is likely to increase. Rehabilitation and discharge planning in this population can be met with significant delays and prolonged hospital stay leading to bed shortages for acute and elective admissions. Planning care for these patients relies on a multidisciplinary approach with allied healthcare providers. The number of hip fracture patients in our hospital averages between 450–500/annum, the second largest number in the North West. The current average length of stay for the hip fracture patients is 22.9 days. We evaluated the impact and performance of a pilot early supported discharge service (ESD) for patients admitted with a hip fracture. The pilot period commenced 22 September 2014 for 3 months and included an initial phase to set up the service and supporting processes, followed by the recruitment of 20 patients during the pilot period. The length of stay and post-discharge care was reviewed. The journey of 20 patients was evaluated. The length of stay was dramatically reduced from an average of 22.9 days to 8.8 days in patients on the ESD pathway. Family feedback showed excellent results with communication regarding the ESD pathway and relatives felt the ESD helped patients return home (100% positive feedback). Prolonged recumbency adversely affects the long-term health of these patients leading to significant morbidity such as pressure sores, respiratory tract infections and loss of muscle mass leading to weakness. Mortality is also a significant risk for these patients. Longer hospital stays lead to disorientation, institutionalisation and loss of motivation. Enhancing self-efficacy has been shown to improve balance, confidence, independence and physical activity. This pilot has proven that the Fracture Neck of Femur ESD service can significantly reduce the length of hospital stay and also deliver excellent patient and family feedback. The benefits of patients with a lower length of stay, with effective rehabilitation in hospital and within the home, will provide significant benefits to the Wirral healthcare economy

Purpose. To describe a 10-year long history of recurrent displacement and infection in a 37 yo female patient, HIV+/HCV+, with an history of drug addiction. Clinical History. Starting from avascular necrosis of the hip (caused by prolonged HAART therapy), the patient underwent first uncemented THA in 2003. One month after implant a septic mobilization due to local abscess was treated with first two stage revision surgery (modular stem with use of retention liner for intraoperatory instability and dislocation of the implant) that lasted for almost 6 years. After 6 years of apparent good clinical condition and stability of the implants, the patient came back with a septic state of the hip, and recurrent instability, caused by complete abruption of the cup from acetabulum (Figure 1) Another two stage revision was planned; patient suffered dislocation of the spacer in first hours after intervention and 3 months later was performed second stage revision (stem with modular neck and head, cup with augmentation metal liner). Three days later patient suffered from another dislocation, so implant was further revised (change of modular neck + dual mobility head/cup), and a pelvipodalic cast was even made, considering the poor compliance of the patient,. One month later, due to another local septic state of the hip and in consideration of clinical history, a DAIR procedure was performed with revision of limited modular components until intraoperative stability was assessed (metal spacer + metal liner + dual mobility head and cup). For further assurance, an external fixator was placed around the hip (Figure 2). Results. After last intervention no dislocation occurred and external fixation was removed with success after 2 months. Clinical outcome at 2 years showed a good functional outcome, and painless walking with only one crutch and limited limping. Discussion. This is a challenging case in which the comorbidity of immunosuppression, poor compliance of the patient and multiple hip revision surgery, started a very long sequence of complications and led to poor clinical results for years. Although the use of modularity aids reaching good stability and function in this kind of revision surgery, only a good control of general conditions of the patient and a multidisciplinary approach to correct patient's lifestyle has brought to stability and “up to now” endurance for this THA implant

To audit adherence to the British Orthopaedic Association and British Association of Plastic, Reconstructive and Aesthetic Surgeons 2009 review of the acute management of severe open lower limb fractures (BOAST4). Audit: Retrospective study of adherence to BOAST4 standards of 37 cases treated at Derriford Hospital between March 2010 and 2011. Intervention: a multidisciplinary approach towards the management of such injuries. Assigning department-specific roles across all specialities involved and establishing an early patient transfer pathway from non-specialist centres in the region. Re-audit: Prospective data collection of adherence to BOAST4 of 18 cases between October 2011 and April 2012. Eleven of 15 standards were comparable. Statistical analysis was performed using Fisher's exact test (p≤0.05). Six standards showed statistically significant improvement: antibiotic therapy; regular assessment of neurovascular status; urgent surgery for contaminated wounds; initial wound care; appropriate splinting and early patient transfers. One standard was adhered to in all cases. 3 standards showed improvement, although not statistically significant and 1 standard remained consistently low in adherence. Although doctors are familiar with BOAST4, many are not aware of the specific details. A coordinated and informed multidisciplinary team has enabled the successful application of an evidenced-based approach to the management these injuries

Purpose of the study. Fibromatosis is a benign, but locally aggressive tumour. We had a series of patients who had a high rate of recurrence though they had a wide surgical excision. The question raised was whether there are newer treatment modalities with a higher success rate. We did a retrospective study and review of the literature in order to see if there was anything new that can help us reduce recurrences. Materials and Methods. A retrospective study of all patients who presented with histologically confirmed fibromatosis at an orthopaedic practice in the past 19 years was conducted. Age of the patient at first presentation; sex; tumour site; surgery performed; histological results; first line of treatment and recurrence rate were reviewed. Patients were also contacted telephonically in order to know if they had any recurrence that was managed by another orthopaedic surgeon. Results. We evaluated 17 patients of which 8 were males and 9 females. The mean age was 25.87 years (range 2–52 years). All of the primary sites were extra abdominal. Median follow up was 3.9 years (0–9) with a mean recurrence rate of 2.3 times. All the patients were treated with a wide marginal surgical excision without adjuvant therapy. Conclusion. Fibromatosis has a high recurrence rate with our current treatment modalities. Complete surgical excision does not guarantee a good outcome. A wide variety of treatment modalities are available. Non-surgical treatment includes: hormonal therapies; NSAIDs; chemotherapy; and radiotherapy. Wide surgical excision is the mainstay of treatment but a multidisciplinary approach is necessary in order to optimize the efficacy of our treatment. Level of evidence: Level III. NO DISCLOSURES

Aims

The standard of wide tumour-like resection for chronic osteomyelitis (COM) has been challenged recently by adequate debridement. This paper reviews the evolution of surgical debridement for long bone COM, and presents the outcome of adequate debridement in a tertiary bone infection unit.

Full-thickness burns around the knee can involve the extensor mechanism. The gastrocnemius flap is well described for soft tissue reconstruction around the knee. We describe a method where a Whichita Fusion Nail¯ knee arthrodesis, combined with a medial gastrocnemius muscle flap was used to salvage the knee and preserve the lower leg following a full-thickness contact burn. The gastrocnemius flap for wound coverage of an open knee joint was originally described in 1970 and remains the workhorse for soft tissue knee reconstruction. There are a number of local alternatives including the vastus lateralis, medialis and sartorius flap; and perforator flaps such as the medial sural artery perforator island flap and islanded posterior calf perforator flap, however many of these are unsuitable for larger defects. Full-thickness burns around the knee can put the extensor mechanism at risk and subsequent rupture is a possible consequence. The gastrocnemius flap has been used to cover a medial knee defect with exposed joint cavity following a burn and also been used in post burn contracture release around the knee. The primary indication for Wichita fusion nail is a failed total knee replacement. It allows intramedullary stabilization with compression at the arthrodesis site to stimulate bone union. With fusion rates reported up to 100% and low complication rates as compared to other methods of fusion, the technique has a useful role in limb salvage type procedures. While use of the gastrocnemius flap in knee burns has been described before we believe this is the first time that this combination of techniques, namely knee arthrodesis with soft tissue reconstruction using a gastrocnemius flap, has been reported. Combining these procedures with a multidisciplinary approach provides a useful alternative leading to limb salvage and avoiding the need for an above knee amputation when extensor reconstruction is not possible

The Dawn Hip - An Effective Strategy to Improve the Management of Traumatic Hip Fractures. Introduction. Traumatic hip fractures are managed with nationwide standards, and are regularly audited and published. A previous audit last year at the William Harvey revealed 66% of hip fractures were operated within 48 hours, compared to the national average of 75%. We implemented a strategy to improve this target by introducing the ‘Dawn Hip’ - a hip fracture operation which is prepared for surgery at 8am on the Emergency (CEPOD) list. Methods. Over a two month period after the introduction of the ‘Dawn hip’, the number of hip operations and start time on the CEPOD list were audited. Performance data were extrapolated from the National Hip Fracture Database (NHFD) and compared nationally. Results. Three months prior to the ‘Dawn hip’ the mean start time of surgery on the CEPOD list was 9.50am. Two months since the introduction of the dawn hip, 67% of all trauma hip operations were done on the CEPOD list. The mean start time of the CEPOD list improved to 8.38am. Data from the NHFD revealed 81% of traumatic hip fractures were operated on within 48 hours, with the national average being 80%. Conclusion. This is an effective strategy which increases efficiency of existing resources and improves hospital services and patient care. It requires a multidisciplinary approach and participation from both managerial and clinical departments. This strategy not only optimises the care we provide for hip fractures, but also increases trauma list space for other pending trauma operations. By meeting nationwide targets, the trust is rewarded with cash incentives, which is used to further improve services. In the current economic climate, this represents a method of optimising healthcare, increasing cost savings and maximising productivity and efficiency

Infection after knee arthroplasty is a devastating complication. Our aim is to present our outcomes of treating infected knee replacements at a tertiary referral centre. We performed a consecutive, retrospective case series of all revision knee arthroplasty for infection between January 2006 and December 2008. Case notes were reviewed and data collated on the date and institution of primary arthroplasty, procedures undertaken at our institution, microbiology and bone loss post first stage, serological markers (C-reactive protein, ESR) prior to second stage and outcome. During this three year period we performed 430 knee revision operations. 51 were in the presence of deep chronic infection. 90% were referred from other hospitals. Overall infection was successfully eradicated in 69%. Nineteen patients underwent repeat two-stage and overall eleven (58%) patients had successful eradication of infection with multiple two-stages. Of these 47% had F3/T3, the highest grading of Anderson Orthopaedic Research Institute bone loss indicating no metaphyseal bone. A further 12% had bicondylar deficiency on the tibia and no femoral metaphyseal bone (F3/T2b). Multidrug resistance present in 69% and 47% were infected with multiple organisms. All members of the unsuccessful outcome group had at least one multidrug resistant organism compared to 43% in the successful cohort (P=0.0002). Multiple organisms are associated with an unsuccessful outcome (P=0.056). Serological markers were not significantly different between the successful and unsuccessful outcome groups. Where the referring hospital had attempted revision and failed, the chance of eradicating infection dropped from 75% to 58% and the rate of above knee amputation was twelve times higher (3% vs. 36%). Custom constrained, rotating hinge prostheses enable aggressive soft tissue debridement including ligaments. Successful two-stage requires a multidisciplinary approach including tissue viability nurses, microbiologists and plastic surgeons. Where units lack revision expertise this series suggests early referral increases the chance of limb salvage
