Abstract. Objectives. Epiphysiodesis is a commonly used treatment for lower limb angular deformities. However, in recent years, distal tibial growth modulation using ‘eight plates’ or screws has emerged as an alternative treatment for paediatric
Abstract. Skeletal kinematics are traditionally measured by motion analysis methods such as optical motion capture (OMC). While easy to carry out and clinically relevant for certain applications, it is not suitable for analysing the ankle joint due to its anatomical complexity. A greater understanding of the function of healthy ankle joints could lead to an improvement in the success of ankle-replacement surgeries. Biplane video X-ray (BVX) is a technique that allows direct measurement of individual bones using highspeed, dynamic X-Rays. Objective. To develop a protocol to quantify in-vivo
We have studied the relationship between movements of the
The aim of this study was to evaluate the relationship between the location of the insertion point of the AT into the posterior aspect of the calcaneus and the PF. Two hundred and two feet were evaluated from MRI scans. Ninety-seven women and one hundred and five men with a mean age of 40.15±18.58 were included in this study. Two independent investigators measured the horizontal distance from the most anterior point of the calcaneus to the most posterior part of the PF (A), including the horizontal length of the calcaneus (B). Moreover, distance between the most inferior point of the calcaneus and the most inferior part of the AT insertion into the calcaneus (C) and height of the posterior aspect of the calcaneus (D) were measured. Patients were divided into three groups based on age (I - patients younger than 18, II − 18–65, III - older than 65The all obtained mean values showed high sexual dimorphism between genders. However, when standardized ratios were compared, no statistically significant sexual differences were noted (p>0.05). Although previous studies have reported a correlation between the PF, age and gender, this correlation was not found in our study. Based on the obtained results, this study concludes that age and sex do not influence the morphology of the PF. However, aging strongly affects the location of the AT insertion point. Therefore, we believe this is the key factor which influence the relationship between the AT and PF.

There has been a significant increase in waiting times for elective surgical procedures in orthopaedic surgery as a result of the coronavirus disease 2019 (COVID-19) pandemic. As per the hospital policy, patients awaiting elective surgery for more than 52 weeks were offered a consultant-led harm review. The aim of this study was to objectively assess the impact of this service on the field of foot and ankle surgery. The data from harm review clinics at a District General Hospital related to patients waiting to undergo elective
Abstract. Objectives. Ankle fractures have an incidence of around 90,000 per year in the United Kingdom. They affect younger patients following high energy trauma and, in the elderly, following low energy falls. Younger patients with pre-existing comorbidities including raised BMI or poor bone quality are also at risk of these injuries which impact the bony architecture of the joint and the soft tissues leading to a highly unstable fracture pattern, resulting in dislocation. At present, there is no literature exploring what effect ankle fracture-dislocations have on patients’ quality of life and activities of daily living, with only ankle fractures being explored. Methods. Relevant question formatting was utilised to generate a focused search. This was limited to studies specifically mentioning ankle injuries with a focus on ankle fracture-dislocations. The number of patients, fracture-dislocation type, length of follow up, prognostic factors, complications and outcome measures were recorded. Results. 939 fractures were included within the studies. Eight studies looked at previously validated
Osteotomies in the musculoskeletal system are joint preserving procedures to correct the alignment of the patient. In the lower limb, most of the pre-operative planning is performed on full leg weightbearing radiographs. However, these images contain a 2-dimensional projection of a 3-dimensional deformity, lack a clear visualization of the joint surface and are prone to rotational errors during patient positioning. Weightbearing CT imaging has demonstrated to overcome these shortcomings during the first applications of this device at level of the
Varus ankle osteoarthritis (OA) is typically associated with peritalar instability, which may result in altered subtalar joint position. This study aimed to determine the extent to which total ankle replacement (TAR) in varus ankle OA can restore the subtalar position alignment using 3-dimensional semi-automated measurements on WBCT. Fourteen patients (15 ankles, mean age 61) who underwent TAR for varus ankle OA were retrospectively analyzed using semi- automated measurements of the hindfoot based on pre-and postoperative weightbearing WBCT (WBCT) imaging. Eight 3-dimensional angular measurements were obtained to quantify the ankle and subtalar joint alignment. Twenty healthy individuals were served as a control groups and were used for reliability assessments. All ankle and hindfoot angles improved between preoperative and a minimum of 1 year (mean 2.1 years) postoperative and were statistically significant in 6 out of 8 angles (P<0.05). Values The post-op angles were in a similar range to as those of healthy controls were achieved in all measurements and did not demonstrated statistical difference (P>0.05). Our findings indicate that talus repositioning after TAR within the ankle mortise improves restores the subtalar position joint alignment within normal values. These data inform
To be able to assess the biomechanical and functional effects of ankle injury and disease it is necessary to characterise healthy ankle kinematics. Due to the anatomical complexity of the ankle, it is difficult to accurately measure the Tibiotalar and Subtalar joint angles using traditional marker-based motion capture techniques. Biplane Video X-ray (BVX) is an imaging technique that allows direct measurement of individual bones using high-speed, dynamic X-rays. The objective is to develop an in-vivo protocol for the hindfoot looking at the tibiotalar and subtalar joint during different activities of living. A bespoke raised walkway was manufactured to position the
Plantar fasciitis (PF) is one of the widespread conditions causing hindfoot pain. The most common presenting symptoms are functional limitation and pain (first step and activity) on plantar surface of the foot. The non-operative treatments provide complete resolution of pain in 90% of patients, but functional limitation still remains as a risk factor for recurrency of PF. Although the number of non-operative treatment options showing efficacy on pain and functional limitation are excessive, the evidences are limited for functional limitation. Additionally, Mulligan mobilization with movement (MMWM) in Chronic Plantar Fasciitis has been poorly studied in the literature. According to these findings, the study was aimed to determine effectiveness of Mulligan mobilization with movement on Chronic Plantar Fasciitis. A total of 25 patients (40 feet) with chronic PF were included in the study. The patients were randomly divided into Mulligan concept rehabilitation group (PF-M, n=20 feet) and Home Rehabilitation group (PF-H, n=20 feet). (MMWM),
Chronic Achilles tendinopathy is characterised by sub-acute inflammation with pro-inflammatory type 1 macrophages (M1), tissue degeneration and consequent partial or total tendon injury. Control of the inflammatory response and M1-to-M2 macrophage polarisation can favour tendon healing both directly and indirectly, by allowing for the regenerative process driven by local mesenchymal stem cells. Ten patients (3 females and 7 males aged between 32 and 71 years old) with partial Achilles tendon injury were treated with injections of autologous peripheral blood mononuclear cells (PB-MNCs). The cell concentrate was obtained from 100-120 cc of each patient's blood with a selective point-of-care filtration system. PB-MNCs remained trapped in the filter and were injected immediately after sampling. Around 60% of the PB-MNC concentrate was injected directly into the injured area, while the remaining 40% was injected in smaller amounts into the surrounding parts of the Achilles tendon affected by tendinosis. All patients were evaluated both clinically with the help of the American Orthopaedic
Background and aims. Hallux rigidus in the metatarsophalangeal joint (MTPJ) can be treated with arthroplasty to reduce pain and enhance motion. Few studies have investigated the functionality and the survival of HemiCap arthroplasty. Primarily we aimed to examine the medium to long-term functionality and the degree of pain after surgery. Secondarily the failure and revision rate of HemiCap implants. Methods. A total of 106 patients were operated with HemiCap arthroplasty (n=114) from 2006 to 2014, median age 53 (16 to 80) years, 78 females, 37 dorsal flange (DF) implants. Patient charts were reviewed retrospectively to collect revision data. Pre operative Coughlin/Shurnas arthrosis degree, hallux valgus (HV), intermetatarsalintermetatarsal (IM) and Distal Metaphyseal Articular Angle (DMAA) angles was were measured. Pre- and post operative 3 weeks, 6 months, 1 and 2 year2-year pain levels of the first MTPJ by Visuel Analog Skala (VAS 1–10), American Orthopaedic
Abstract. Objectives. Achilles tendon ruptures are common in the UK, with data demonstrating a significant rise in incidence over the past years. Chronic Achilles ruptures have been less well defined in literature, and repair techniques vary significantly. A surge in publications reporting various management options for chronic Achilles ruptures has necessitated a review that systematically maps and summarises current evidence regarding treatments and identifies areas for future research. This scoping review aims to improve knowledge of various treatment strategies and their associated outcomes, thereby aiding clinicians in optimising treatment protocols. Methods. The Arksey and O'Malley, Levac and Peters frameworks were used. A computer-based search in PubMed, Embase, Emcare, Cinahl, ISI Web of Science and Scopus was performed for articles reporting the treatment of chronic Achilles ruptures. Two reviewers independently performed title/abstract and full text screening according to a pre-defined selection criteria. Results. A total of 747 articles were identified, of which 73 were finally included. Various management strategies were described with flexor hallucis longus tendon transfer being the most common. The American Orthopaedic
Introduction and Objective. Management of gap non-union of the tibia, the major weight bearing bone of the leg remains controversial. The different internal fixation techniques are often weighed down by relatively high complication rates that include fractures which fail to heal (non-union). Minimally invasive techniques with ring fixators and bone transport (distraction osteogenesis) have come into picture as an alternative allowing alignment and stabilization, avoiding a graduated approach. This study was focused on fractures that result in a gap non-union of > 6 cm. Ilizarov technique was employed for management of such non-unions in this case series. The Ilizarov apparatus consists of rings, rods and kirschner wires that encloses the limb as a cylinder and uses kirschner wires to create tension allowing early weight bearing and stimulating bone growth. Ilizarov technique works on the principle of distraction osteogenesis, that is, pulling apart of bone to stimulate new bone growth. Usually, 4–5 rings are used in the setup depending on fracture site and pattern for stable fixation. In this study, we demonstrate effective bone transport and formation of gap non-union more than 6 cm in 10 patients using only 3 rings construct Ilizarov apparatus. Materials and Methods. This case study was conducted at Dr. D. Y. Patil Medical Hospital, Navi Mumbai, Maharashtra, India. The study involved 10 patients with a non-union or gap > 6 cm after tibial fracture. 3 rings were used in the setup for the treatment of all the patients. Wires were passed percutaneously through the bone using a drill and the projecting ends of the wires were attached to the metal rings and tensioned to increase stability. The outcome of the study was measured using the Oxford Knee scoring system, Functional Mobility Scale, the American
Lisfranc injuries are uncommon and can be challenging to manage. There is considerable variation in opinion regarding the mode of operative treatment of these injuries, with some studies preferring primary arthrodesis over traditional open reduction and internal fixation (ORIF). We aim to assess the clinical and radiological outcomes of the patients treated with ORIF in our unit. This is a retrospective study, in which all 27 consecutive patients treated with ORIF between June 2013 and October 2018 by one surgeon were included with an average follow-up of 2.4 years. All patients underwent ORIF with joint-sparing surgery by a dorsal bridging plate (DBP) for the second and third tarsometatarsal (TMT) joint, and the first TMT joint was fixed with trans-articular screws. Patients had clinical examination and radiological assessment, and completed American Orthopaedic
Biomedical imaging is essential in the diagnosis of musculoskeletal pathologies and postoperative evaluations. In this context, Cone-Beam technology-based Computed Tomography (CBCT) can make important contributions in orthopaedics. CBCT relies on divergent cone X-rays on the whole field of view and a rotating source-detector element to generate three-dimensional (3D) volumes. For the lower limb, they can allow acquisitions under real loading conditions, taking the name Weight-Bearing CBCT (WB-CBCT). Assessments at the
Abstract. Objectives. Diabetes has been associated with greater risk of complications and prolonged postoperative recovery following ankle trauma. Our cohort study seeks to review the operative management and outcomes of ankle fractures in diabetic adults relative to non-diabetic adults. Methods. Cases were identified using ICD-10 coding criteria. 572 patients from Jan 2016–2019 presented with ankle fractures; 34 in diabetic patients. Mechanism of injury and stability were determined from the index radiograph using a validated Lauge-Hansen classification algorithm. Admission, primary post-operative and discharge radiographs were reviewed independently by two
Background. Avulsion fractures of the base of the fifth metatarsal are some of the commonest foot injuries. The robust scientific evidence on the optimal non-operative treatment of these fractures is scant. We designed and conducted a prospective randomised non-inferiority controlled trial of symptomatic treatment versus cast immobilisation with the null hypothesis that cast immobilisation gave substantial benefit over the symptomatic treatment in terms of patient reported outcome measures(PROMs). The alternative hypothesis was that symptomatic treatment was not inferior. Methods. The primary outcome was the validated Visual Analogue Scale
Syndesmotic ankle injuries are present in one fourth of all ankle trauma and may lead to chronic syndesmotic instability as well as posttraumatic ankle osteoarthritis. The main challenge remains distinguishing them from other types of ankle trauma. Currently, the patient's injured and non-injured ankles are compared using plain radiographs to determine pathology. However, these try to quantify 3D displacement using 2D measurements techniques and it is unknown to what extent the 3D configuration of the normal ankle syndesmosis is symmetrical. We aimed to assess the 3D symmetry of the normal ankle syndesmosis between the right and left side in a non- and weightbearing CT. In this retrospective comparative cohort study, patients with a bilateral non-weightbearing CT (NWBCT; N=28; Mean age=44, SD=17.4) and weight-bearing CT (WBCT; N=33; Mean age=48 years; SD=16.3) were analyzed. Consecutive patients were included between January 2016 and December 2018 when having a bilateral non-weightbearing or weightbearing CT of the
