Introduction

The purpose of this study was to analyse the efficacy and complications associated with the use of Calcium Sulphate synthetic bone graft in a paediatric population. There are no published articles on the use in children.

Introduction

Osteotomy is a key step in distraction osteogenesis. Various techniques of osteotomy have been described with its own benefits and pitfalls. Percutaneous osteotomy using multiple drill holes is one of the most widely used osteotomy techniques. It still remains a challenge however to keep the drill holes aligned prior to the osteotomy. Moreover, the efficacy of percutaneous irrigation practice to keep the temperature low during drilling with this technique is also debatable. With an aim to overcome these challenges, we are introducing a device called the Double Barrel Drill Sleeve (DBDS) to perform percutaneous osteotomies. We attempted to compare this method to the conventional multiple drill holes technique using laboratory experiments and clinical data.

Introduction

A significant burden of disease exists with respect to critical sized bone defects; outcomes are unpredictable and often poor. There is no absolute agreement on what constitutes a “critically-sized” bone defect however it is widely considered as one that would not heal spontaneously despite surgical stabilisation, thus requiring re-operation. The aetiology of such defects is varied. High-energy trauma with soft tissue loss and periosteal stripping, bone infection and tumour resection all require extensive debridement and the critical-sized defects generated require careful consideration and strategic management. Current management practice of these defects lacks consensus. Existing literature tells us that tibial defects 25mm or great have a poor natural history; however, there is no universally agreed management strategy and there remains a significant evidence gap. Drawing its origins from musculoskeletal oncology, the Capanna technique describes a hybrid mode of reconstruction. Mass allograft is combined with a vascularised fibula autograft, allowing the patient to benefit from the favourable characteristics of two popular reconstruction techniques. Allograft confers initial mechanical stability with autograft contributing osteogenic, inductive and conductive capacity to encourage union. Secondarily its inherent vascularity affords the construct the ability to withstand deleterious effects of stressors such as infection that may threaten union. The strengths of this hybrid construct we believe can be used within the context of critical-sized bone defects within tibial trauma to the same success as seen within tumour reconstruction.

Introduction

The use of vascularised fibula grafts is an accepted method for reconstructing the distal femur following resection of malignant childhood tumours. Limitations relate to the mismatch of the cross-sectional area of the transplanted fibula graft and thel ocal bone, instability of the construct and union difficulties. We present midterm results of a unique staged technique—an immediate defect reconstruction using a double-barrel vascularised fibula graft set in in A-frame configuration and a subsequent intramedullary femoral lengthening.

Introduction

Legg-Calve-Perthes (Perthes Disease) was first recognised by three physicians, Arthur Legg (1874–1939), Jacqui Calve (1875–1954) and George Perthes (1869 – 1927) in 1910. Perthes disease is a rare childhood condition that affects the hip. It occurs when the blood supply to the femoral head is disrupted. Without this blood supply, the bone cells die and avascular necrosis can occur. The Herring classification is used to diagnose the stages of Perthes Disease. It is an important prognostic factor. There are three classifications, Herring A, B and C. Herring A has no involvement of the lateral pillar with no density changes noted on x-ray. Herring B has at least 50% of the lateral pillar height maintained on x-ray. Herring C has less than 50% of the lateral pillar height on x-ray (Herring et al, 1992). Children with Perthes disease require specialist Limb Reconstruction team throughout their treatment journey, this includes Orthopaedic surgery and therapy (Physiotherapy and Occupational Therapy). The National Limb Reconstruction Therapy Team is based at the National Orthopaedic Hospital, Cappagh. The therapy team consists of 1 Clinical Specialist Physiotherapist, 1 Senior Physiotherapist and 1 Senior Occupational Therapist who provide input to this cohort. This study aims to analyse the importance of a comprehensive pre-operative assessment by the therapy team (Physiotherapist and Occupational Therapist) to maximise patient outcomes post operatively.

The Masquelet technique, also known as the ‘induced membrane technique’ has been utilised in adult reconstruction with varied success. However, there is limited literature on its use in children and this study aims to share our experience.

Introduction

Open fragility ankle fractures involve complex decision making. There is no consensus on the method of surgical management. Our aim in this study was to analyse current management of these patients in a major trauma centre (MTC).

Introduction

The various problems that are managed with circular external fixation (e.g. deformity, complex fractures) also typically require serial plain x-ray imaging.

One of the challenges here is that the relatively radio-opaque components of the circular external fixator (e.g. the rings) can obscure the view of the area of interest (e.g. osteotomy site, fracture site).

In this presentation we describe how the geometry of the x-ray beam affects the produced image and how we can use knowledge of this to our advantage.

Whilst this can be applied to any long bone, we have focused on the tibia, given that it's the most common long bone that is treated by circular external fixation.

Introduction

The management of open long bone fractures is well described and has been standardised through a number of well-established guidelines. However, there is no consensus regarding the application of local antibiotics into the open fracture site as a means of reducing infection rates.

Introduction

Ankle fractures in the elderly have been increasing with an ageing but active population and bring with them specific challenges. Medical co-morbidities, a poor soft tissue envelope and a requirement for early mobilisation to prevent morbidity and mortality, all create potential pitfalls to successful treatment. As a result, different techniques have been employed to try and improve outcomes. Total contact casting, both standard and enhanced open reduction internal fixation, external fixation and most recently tibiotalocalcaneal (TTC) nailing have all been proposed as suitable treatment modalities. Over the past five years popular literature has begun to herald TTC nailing as an appropriate and contemporary solution to the complex problem of high-risk ankle fragility fractures. We sought to assess whether, within our patient cohort, the outcomes seen supported the statement that TTC has equal outcomes to more traditional open reduction internal fixation (ORIF) when used to treat the high-risk ankle fragility fracture.

Introduction

LIMB-Q Kids is a new patient-reported outcome measure (PROM) for children with Lower limb differences (LLDs). The objective is to conduct an international field test study.

Introduction

External fixation (EF) devices are commonly used in the management of complex skeletal trauma, as well as in elective limb reconstruction surgery for the management of congenital and acquired pathology. The subsequent removal of an EF is commonly performed under a general anaesthetic in an operating theatre. This practice is resource intensive and limits the amount of operating theatre time available for other surgical cases. We aimed to assess the use of regional anaesthesia as an alternative method of analgesia to facilitate EF removal in an outpatient setting.

Introduction

External fixators are common surgical orthopaedic treatments for the management of complex fractures and in particular, the use of circular frame fixation within patients requiring limb reconstruction. It is well known that common complications relating to muscle length and patient function without rehabilitation can occur. Despite this there remains a lack of high-quality clinical trials in this area investigating the role of physiotherapy or rehabilitation in the management of these patients. We aim to complete a systematic review of rehabilitation techniques for patients undergoing external fixator treatment for Limb Reconstruction of the lower limb.

Introduction

Snapping hip syndrome is a common condition affecting 10% of the population. It is due to the advance of the iliotibial band (ITB) over the greater trochanter during lower limb movements and often associated with hip overuse, such as in athletic activities. Management is commonly conservative with physiotherapy or can be surgical to release the ITB. Here we carry out a systematic review into published surgical management and present a case report on an overlooked cause of paediatric snapping hip syndrome.

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.

Introduction

The vast majority of orthopaedic surgeons use C-arm fluoroscopy in the operating theatre when building a circular external fixator. In the absence of previous research in this area, we hypothesised that the surgeon who builds a circular external fixator is exposed to a greater amount of radiation purely as a result of the presence of the metallic fixator in the x-ray beam. The aim of our study therefore was to investigate how the presence of a circular external fixator affects the radiation dose to the surgeon and the surgical assistant.

Introduction

Osteomyelitis is a challenge in diagnosis and treatment. 18F-FDG PET-CT provides a non-invasive tool for diagnosing and localizing osteomyelitis with a sensitivity reaching 94% and specificity reaching 100%. We aimed to assess the agreement in identifying the geographic area of infected bone and planned resection on plain X-ray versus 18F-FDG PET-CT.

Introduction

We present a case of a 49-year-old patient who initially presented in May 2020 with an open pilon fracture. Managed with initial debridement, fixation and flap - who subsequently underwent circular frame application for failure of fixation, requiring a transport to fusion frame who developed beta-haemolytic streptococcus A within the site of the proximal corticotomy.

Introduction

The FitBone lengthening nail (Orthofix UK) is an intramedullary device licensed for the lengthening of long bones in adults in the UK. It contains a motor powered by electricity transmitted via an induction coil placed underneath the skin. It was developed in Germany two decades ago but uptake in the UK has only started more recently. The aim of this study was to review the first cohort of FitBone lengthening nails in a unit with significant experience of other lengthening nails (including PRECICE and Stryde).

Introduction

Open tibial fractures typically occur as a consequence of high energy trauma in patients of working age resulting in high rates of deep infection and poor functional outcome. Whilst improved rates of limb salvage, avoidance of infection and better ultimate function have been attributed to improved centralisation of care in orthoplastic units, there remains no universally accepted method of definitive management of these injuries. The aim of this study is to the report the experience of a major trauma centre utilising circular frames as definitive fixation in patients sustaining Gustilo-Anderson (GA) 3B open fractures

Introduction

Adjusting an external fixator can be a daunting process for patients. Despite comprehensive training, patients often request supervision for the initial adjustments which may result in a prolonged hospital stay. Following the introduction of telemedicine during the pandemic we believed that this could be utilised to support patients with their fixator adjustments. A quality improvement project was implemented to assess and evaluate a change in practice from existing Face to Face support to a telemedicine format. The aim of the project was to reduce median length of stay (LOS).

This edition of Cochrane Corner looks at some of the work published by the Cochrane Collaboration, covering interventions for treating distal femur fractures in adults; ultrasound and shockwave therapy for acute fractures in adults; and local corticosteroid injection versus placebo for carpal tunnel syndrome.

Introduction

Patient-reported outcome measures (PROMs) has gained momentum in the orthopaedic literature. The GOAL-LD (Gait Outcomes Assessment List for Limb Deformity) incorporates the framework of The WHO International Classification of Functioning, Disability and Health and correlates highly with the Paediatric Outcomes Data Collection Instrument (PODCI) when applied in a limb reconstruction setting. The Royal Children's Hospital Melbourne, Australia, supported by The University of Melbourne is designing and implementing a Limb Reconstruction Registry, prospectively enrolling patients with a number of key conditions and provide a mechanism for capturing surgical data and PROMs at regular follow-up intervals. LimbDREAM (The Limb Reconstruction Registry of Experience, Aspiration and Measures) has begun recruiting participants, and this paper serves as a narrative review of our design and implementation process.

Introduction

External fixators are attached to bones with percutaneous pins and wires inserted through soft tissues and bone increasing the risk of infections. Such infections compromise patient outcomes e.g., through pin loosening or loss, failure of fixator to stabilise the fracture, additional surgery, increased pain, and delayed mobilisation. These infections also impact the healthcare system for example, increased OPD visits, hospitalisations, treatments, surgeries and costs. Nurses have a responsibility in the care and management of patients with external fixators and ultimately in the prevention of pin-site infection. Yet, evidence on best practices in the prevention of pin-site infection is limited and variation in pin-site management practices is evident. Various strategies are used for the prevention of pin-site infection including the use of different types of non-medicated and medicated wound dressings. The aim of this retrospective study was to investigate the use of dry gauze or iodine tulle dressings for the prevention of pin-site infections in patients with lower limb external fixators.

Introduction

Despite the established guidelines on lower extremity free flap reconstruction by the British Orthopaedic Association Standard for Trauma (BOAST-4) the post-operative care has yet to be standardised. There is currently no coherent evidence in the literature regarding clinical monitoring, warming, dangling and compression; the optimal regimes and their respective physiological benefits. The aim of this study is to survey all UK Major Trauma Centres (MTCs) with regards to the post-operative care of lower extremity free flaps and elucidate the current protocols for clinical monitoring, warming, dangling and compression.

Introduction

Introduction: Pin site infection is a common complication during treatment with a circular frame external fixator and increases time and support patients require from the limb reconstruction team. Wound swabs were not routinely sent by the clinical nurse specialists prior to this study, with most pin site infections treated as Staphylococcus aureus with flucloxacillin (clindamycin in penicillin allergy). The aim of this study was to ascertain whether routine sending of wound swabs in pin site infection would change antibiotic treatment.

Introduction

Circular external fixators are fundamental to lower limb reconstruction, primarily in situations with a high risk of infection such as open fractures. During the Covid-19 pandemic, use of circular frames in our unit decreased, following departmental approval, due to resource management and in keeping with BOA guidelines as we opted to “consider alternative techniques for patients who require soft tissue reconstruction to avoid multiple operations”. These alternatives included the use of internal fixation (plate osteosynthesis and intramedullary nailing) as a measure to reduce the number of hospital attendances for patients and to conserve resources. This change in practice has continued in part following the pandemic with the increased use of internal fixation in cases previously deemed unsuitable for such techniques. We present our experience of this treatment strategy in the management of complex lower limb injuries, focusing on outcomes and consider the lessons learnt.

Introduction

This study reports on minimum 2 year follow up outcomes on functional and quality of life of patients after undergoing bilateral osseointegration in comparison to traditional socket prosthesis.

Introduction

Osseointegration has emerged as a promising alternative to rehabilitating with a traditional socket mounted prosthesis. Advantages have been reported to include improved functional mobility, better osseoperception, improved comfort, reduced pain, better biomechanical alignment and better gait, which all lead to a less restricted lifestyle and significantly improved quality of life. A major concern of the Osseointegrated approach lies in the risk of infections occurring from the permanent transcutaneous opening often referred to as the stoma. Several systematic reviews have indicated that the occurrence of minor infections can be quite common, serious complications are reported to be rare. In addition to commonly anticipated complications including fractures, surgical debridements or revisions, we have identified several significant events in which a patient may require to be readmitted and go through additional surgery. The objective of this study is to examine the rate of occurrence and reports on the best management practices of serious complications across a multi-centre review of more than 1000 osseointegration surgeries.

Introduction

Transtibial osseointegration (TFOI) for amputees has limited but clear literature identifying superior quality of life and mobility versus a socketed prosthesis. Some amputees have knee arthritis that would be relieved by a total knee replacement (TKR). No other group has reported performing a TKR in association with TTOI (TKR+TTOI). We report the outcomes of nine patients who had TKR+TTOI, followed for an average 6.5 years.

Introduction

There is no doubt that the future of limb lengthening lies with internal lengthening. Complication rates are reduced and patient satisfaction is increased. The evolution of internal lengthening peaked with the dual direction, easily inserted and externally controlled PRECICE Nail. It has excelled in performance in accuracy and satisfaction. Its versatility increased with smaller sizes and increased excursion. A field safety notice was issued was issued in October 2021 by the parent company NuVasive. The advice was monitoring of current cases and a hold on implantation until after a review of process. At the National Orthopaedic Hospital Cappagh we elected to remove all implanted nails and assess the nail integrity and physiological changes associated with implantation.

Introduction

Bone transport and distraction osteogenesis have been shown to be an effective treatment for significant bone loss in the tibia. However, traditional methods of transport are often associated with high patient morbidity due to the pain and scarring caused by the external frame components transporting the bone segment. Prolonged time in frame is also common as large sections of regenerate need significant time to consolidate before the external fixator can be removed. Cable transport has had a resurgence with the description of the balanced cable transport system. However, this introduced increasingly complex surgery along with the risk of cable weave fracture. This method also requires frame removal and intramedullary nailing, with a modified nail, to be performed in a single sitting, which raised concern regarding potential deep infection. An alternative to this method is our modified cable transport system with early intramedullary nail fixation. Internal cables reduce pain and scarring of the skin during transport and allow for well controlled transport segment alignment. The cable system is facilitated through an endosteal plate that reduces complications and removes the need for a single-stage frame removal and nailing procedure. Instead, the patients can undergo a pin-site holiday before nailing is performed using a standard tibial nail. Early intramedullary nailing once transport is complete reduces overall time in frame and allows full weight bearing as the regenerate consolidates. We present our case series of patients treated with this modified cable transport technique.

Introduction

At Sheffield Children's Hospital, treatment of leg length discrepancy is a common procedure. Historically, this has been done with external fixators. With the development in intramedullary technology, internal nails have become the preferred modality for long bone lengthening in the adolescent population. However, it is important to review whether this technology practically reduces the known challenges seen and if it brings any new issues. Therefore, the aim of this review is to retrospectively evaluate the therapeutic challenges of 16 fit-bone intramedullary femoral lengthening's at Sheffield Children's Hospital between 2021–2022.

Introduction

Intramedullary lengthening devices have been in use in older children with closed /open growth plates with good success. This study aims to present the early experience of the FITBONE nail since withdrawal of the PRECICE nail.

Introduction

A greater emphasis has been placed on fracture related infection (FRI) orthopaedic practice as a separate entity in recent years. Since the publication of the FRI consensus definition and guidelines, there has been an increase in the published literature on the topic and a move towards considering FRI as separate from general orthopaedic practice and as work that requires a more specialist approach. The aim of this study was to audit current FRI practice in the UK.

Introduction

Percutaneous EndoProsthetic Osseointegration for Limbs (PEPOL) facilitates improved quality of life (QOL) and objective mobility for most amputees discontent with their traditional socket prosthesis (TSP) experience. Some amputees desiring PEPOL have residual bone much shorter than the currently marketed press-fit implant lengths of 14–16 cm, potentially a risk for failure to integrate. We report on the techniques used, complications experienced, the management of those complications, and the overall mobility outcomes of seven patients who had femur distraction osteogenesis (DO) with a Freedom nail followed by PEPOL.

Introduction

Approximately 2,000 Skeletal transcutaneous osseointegration (STOI) procedures have been performed worldwide as of 2020, more than half of which have been performed by the Osseointegration Group of Australia using a press-fit technique with either ILP or OPL implant designs. Despite the consistently demonstrated clinical benefits, concerns regarding potential complications following STOI have slowed its widespread adoption. As more patients are followed for a longer period of time, longitudinal studies have confirmed complication rates are very acceptable, similar to those of total ankle and total elbow replacements. One of the major risk category is implant removal. The primary goal of this study was to investigate the complications and technical issues associated with transtibial osseointegration implant removal due to any cause. The focus here will be on the press-fit ILP and OPL implants, including the indications for removal and patient outcomes following removal.

Introduction

Reconstruction of large defect of tibia following infection is considered as one of the most difficult problem facing the orthopaedic surgeon. Amputation with modern prosthetic fitting is a salvage procedure to treat big defects, which gives a functional result with unpredictable psychological impact.

Introduction

Aneurysmal bone cysts commonly found in lower limbs are locally aggressive masses that can lead to bony erosion, instability and fractures. This has major implications in the lower limbs especially in paediatric patients, with potential growth disturbance and deformity. In this case series we describe radical aneurysmal bone cyst resection and lower limb reconstruction using cable transport and syndesmosis preservation.

Introduction

Introduction: Pre-operative counselling to prepare patients for frame surgery is important to ensure expectations of recovery and rehabilitation are realistic and anxiety is reduced. The aim of the study was to ascertain whether the current clinical nurse specialist frames counselling session (CNS FCS) prepared patients adequately for life with a frame as well as to explore information patients felt was missing.

Introduction

Osteogenesis imperfect (OI) is a geno- and phenotypically heterogeneous group of congenital collagen disorders characterized by fragility and microfractures resulting in long bone deformities. OI can lead to progressive femoral coxa vara from bone and muscular imbalance and continuous microfracture about the proximal femur. If left untreated, patients develop Trendelenburg gait, leg length discrepancy, further stress fracture and acute fracture at the apex of the deformity, impingement and hip joint degeneration. In the OI patient, femoral coxa vara cannot be treated in isolation and consideration must be given to protecting the whole bone with the primary goal of verticalization and improved biomechanical stability to allow early loading, safe standing, re-orientation of the physis and avoidance of untreated sequelae. Implant constructs should therefore be designed to accommodate and protect the whole bone. The normal paediatric femoral neck shaft angle (FNSA) ranges from 135 to 145 degrees. In OI the progressive pathomechanical changes result in FNSA of significantly less than 120 degrees and decreased Hilgenreiner epiphyseal angles (HEA). Proximal femoral valgus osteotomy is considered the standard surgical treatment for coxa vara and multiple surgical techniques have been described, each with their associated complications. In this paper we present the novel technique of controlling femoral version and coronal alignment using a tubular plate and long bone protection with the use of teleoscoping rods.

Aims

Disorders of bone integrity carry a high global disease burden, frequently requiring intervention, but there is a paucity of methods capable of noninvasive real-time assessment. Here we show that miniaturized handheld near-infrared spectroscopy (NIRS) scans, operated via a smartphone, can assess structural human bone properties in under three seconds.

Aims

Chronic osteomyelitis (COM) of the lower limb in adults can be surgically managed by either limb reconstruction or amputation. This scoping review aims to map the outcomes used in studies surgically managing COM in order to aid future development of a core outcome set.

A hip fracture represents the extreme end of osteoporosis, placing a significant burden on secondary care, society, and the individual patient. The National Hip Fracture Database (NHFD) reports each hospital's attainment of the BPT with other measures, along with reporting outcomes. There is clearly wide variability in provision of orthogerriatrician (OG) services across the dataset. Unfortunately, despite overwhelming evidence that provision of an OG service is of benefit, it is presently challenging to recruit to this important specialty within the UK.

Publicly available reports from the NHFD were obtained for each of the 177 participating hospitals for 2017. This was matched with information held within the annual NHFD Facilities Audit for the same period, which include hours of OG support for each hospital. This information was combined with a Freedom of Information request made by email to each hospital for further details concerning OG support. The outcome measures used were Length of Stay (LoS), mortality, and return to usual residence. Comparison was made with provision of OG services by use of Pearson's correlation coefficient. In addition, differences in services were compared between the 25% (44) hospitals delivering outcomes at the extremes for each measure.

Attainment of BPT correlated fairly with LoS (−0.48) and to less of a degree with mortality (−0.1) and return home (0.05). Perioperative medical assessment contributed very strongly with BPT attainment (0.75). In turn perioperative medical assessment correlated fairly with LoS (−0.40) and mortality (−0.23) but not return home (0.02). Provision of perioperative medical assessment attainment was correlated fairly with total OG minutes available per new patient (0.22), total OG minutes available per patient per day (0.29) and number of days per week of OG cover (0.34); with no link for number of patients per orthogeriatrician (0.01). Mortality for the best units were associated with 30% more consultant OG time available per patient per day, and 51% more OG time available per patient. Units returning the most patients to their usual residence had little association with OG time, although had 59% fewer patients per OG, the best units had a 19% longer LoS. For all three measures results for the best had on average 0.5 days per week better routine OG access.

There is no doubt that good quality care gives better results for this challenging group of patients. However, the interaction of BPT, other care metrics, level of OG support and patient factors with outcomes is complex. We have found OG time available per patient per day appears to influence particularly LoS and mortality. Options to increase OG time per patient include reducing patient numbers (ensuring community osteoporosis/falls prevention in place, including reducing in-patient falls); increasing OG time across the week (employing greater numbers/spreading availability over 7 days per week); and reducing LoS. A reduction in LoS has the largest effect of increasing OG time, and although it is dependent on OG support, it is only fairly correlated with this and many other factors play a part, which could be addressed in units under pressure.

Introduction

Virtual fracture clinics (VFC's) aim to reduce the number of outpatient appointments while improving the clinical effectiveness and patients experience through standardisation of treatment pathways. With 4.6% of ED admissions due to trauma the VFC prevents unnecessary face to face appointments providing a cost savings benefit to the NHS.

Introduction

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare condition characterised by bony pain and swelling which may be initially mistaken for bacterial osteomyelitis. The episodic course of the disease may confound the diagnosis and potentially be mistaken for a partial response to antimicrobial therapy. It is an orphan disease and consequently results in many unclear aspects of diagnosis, treatment and follow up for patients. The aim of this study is to evaluate a national tertiary centre's experience with the clinical condition and present one of the largest cohorts to date, emphasizing the vast array of clinical spectrum, course and response to treatment.

Introduction

Mode of non-operative management of thoracolumbar spine fracture continues to remain controversial with the most common modality hinging on bracing. TLSO is the device with a relative extension locked position, and many authors suggest they may have a role in the healing process, diminishing the load transferred via the anterior column, limiting segmental motion, and helping in pain control. However, several studies have shown prolonged use of brace may lead to skin breakdown, diminished pulmonary capacity, weakness of paraspinal musculature with no difference in pain and functional outcomes between patients treated with or without brace.

Increasing expectations from arthroscopic anterior cruciate ligament (ACL) reconstructions require precise knowledge of technical details such as minimum intra-femoral tunnel graft lengths. A common belief of having ≥20mm of grafts within the femoral tunnel is backed mostly by hearsay rather than scientific proof.

We examined clinico-radiological outcomes in patients with intra-femoral tunnel graft lengths <20 and ≥20mm. Primary outcomes were knee scores at 1-year. Secondarily, graft revascularization was compared using magnetic resonance imaging (MRI). We hypothesized that outcomes would be independent of intra-femoral tunnel graft lengths.

This prospective, single-surgeon, cohort study was conducted at a tertiary care teaching centre between 2015–2018 after obtaining ethical clearances and consents. Eligible arthroscopic ACL reconstruction patients were sequentially divided into 2 groups based on the intra-femoral tunnel graft lengths (A: < 20 mm, n = 27; and B: ≥ 20 mm, n = 25). Exclusions were made for those > 45 years of age, with chondral and/or multi-ligamentous injuries and with systemic pathologies. All patients were postoperatively examined and scored (Lysholm and modified Cincinnati scores) at 3, 6 and 12 months. Graft vascularity was assessed by signal-to-noise quotient ratio (SNQR) using MRI. Statistical significance was set at p<0.05.

Age and sex-matched patients of both groups were followed to 1 year (1 dropout in each). Mean femoral and tibial tunnel diameters (P =0.225 and 0.595) were comparable. Groups A (<20mm) and B (≥20mm) had 27 and 25 patients respectively. At 3 months, 2 group A patients and 1 group B patient had grade 1 Lachman (increased at 12 months to 4 and 3 patients respectively). Pivot shift was negative in all patients. Lysholm scores at 3 and 6 months were comparable (P3= 0.195 and P6= 0.133). At 1 year both groups showed comparable Cincinnati scores. Mean ROM was satisfactory (≥130 degrees) in all but 2 patients of each group (125–130 degrees). MRI scans at 3 months and 1 year observed anatomical tunnels in all without any complications. Femoral tunnel signals in both groups showed a fall from 3–12 months indicating onset of maturation of graft at femoral tunnel.

Our hypothesis, clinical and radiological outcomes would be independent of intra-tunnel graft lengths on the femoral aspect, did therefore prove correct. Intra-femoral tunnel graft lengths of <20 mm did not compromise early clinical and functional outcomes of ACL reconstructions. There seems to be no minimum length of graft within the tunnel below which suboptimal results should be expected.

Background

In recent years, ‘Get It Right First Time (GIRFT)’ have advocated cemented replacements in femoral part of Total hip arthroplasty (THA) especially in older patients. However, many studies were unable to show any difference in outcomes and although cemented prostheses may be associated with better short-term pain outcomes there is no clear advantage in the longer term. It is not clear when and why to do cemented instead of cementless.

Introduction

Neck of femur (NoF) fractures have an inherent 6.5% 30-day mortality as per National hip fracture database(2019). Several studies have demonstrated a higher mortality rate in covid positive NoFs but have been unable to demonstrate whether there are risk factors that contribute to the risk of mortality in this patient group or whether COVID is solely responsible for the higher mortality.
