Introduction. Treatment pathways of 5. th. metatarsal fractures are commonly directed based on fracture classification, with Jones types for example, requiring closer observation and possibly more aggressive management. Primary objective. To investigate the reliability of assessment of subtypes of 5. th. metatarsal fractures by different observers. Methods. Patients were identified from our prospectively collected database. We included all patient referred to our virtual fracture clinic with a suspected or confirmed 5. th. metatarsal fracture. Plain AP radiographs were reviewed by two observers, who were initially trained on the 5. th. metatarsal classification identification. Zones were defined as Zone 1.1, 1.2, 1.3, 2, 3, diaphyseal shaft (DS), distal metaphysis (DM) and head. An inter-observer reliability analysis using Cohen's Kappa coefficient was carried out, and degree of observer agreement described using Landis & Koch's description. All data was analysed using IBM SPSS v.27. Results. 878 patients were identified. The two observers had moderate agreement when identifying fractures in all zones, apart from metatarsal head fractures, which scored substantial agreement (K=.614). Zones 1.1 (K=.582), 2 (K=.536), 3 (K=.601) and DS (K=.544) all tended towards but did not achieve substantial agreement. Whilst DS fractures achieved moderate agreement, there was an apparent difficulty with distal DS, resulting in a lot of cross over with DM (DS 210 vs 109; DM 76 vs 161). Slight agreement with the next highest adjacent zone was found when injuries were thought to be in zones 1.2, 1.3 and 2 (K=0.17, 0.115 and 0.152 respectively). Conclusions. Reliability of sub-categorising 5. th. metatarsal fractures using standardised instructions conveys moderate to substantial agreement in most cases. If the region of the fracture is going to be used in an algorithm to guide a management plan and clinical follow up during a virtual clinic review, defining fractures of zones 1–3 needs careful consideration

Aims. Various radiological parameters are used to evaluate a flatfoot deformity and their measurements may differ. The aims of this study were to answer the following questions: 1) Which of the 11 parameters have the best inter- and intraobserver reliability in a standardized radiological setting? 2) Are pre- and postoperative assessments equally reliable? 3) What are the identifiable sources of variation?. Patients and Methods. Measurements of the 11 parameters were recorded on anteroposterior and lateral weight-bearing radiographs of 38 feet before and after surgery for flatfoot, by three observers with different experience in foot surgery (A, ten years; B, three years; C, third-year orthopaedic resident). The inter- and intraobserver reliability was calculated. Results. Preoperative interobserver reliability was high for four, moderate for five, and low for two parameters. Postoperative interobserver reliability was high for four, moderate for five, and low for two parameters. Intraobserver reliability was excellent for all parameters preoperatively as recorded by observer A (PB) and B (MP), and for eight parameters as recorded by observer C (SR). Intraobserver reliability was excellent for ten parameters postoperatively as recorded by observer A and B, and for eight parameters as recorded by observer C. Conclusion. The following parameters can be recommended. For preoperative and postoperative evaluation of flatfoot: anteroposterior, talonavicular coverage angle; lateral, talometatarsal I angle, calcaneal pitch angle, and cuneiform-medial height (high interobserver reliability); and anteroposterior, talometatarsal II angle; lateral, talocalcaneal angle,tibiocalcaneal angle (moderate interobserver reliability). For more experienced observers, we also recommend the anteroposterior talometatarsal I angle (moderate reliability). The inter- and intraobserver reliability for most parameters were similar pre- and postoperatively. The experience of the observer and the definition and ability to measure the parameters themselves were sources of variation. Cite this article: Bone Joint J 2018;100-B:596–602

Aims

The purpose of this study was to assess the success rate and functional outcomes of bone grafting for periprosthetic bone cysts following total ankle arthroplasty (TAA). Additionally, we evaluated the rate of graft incorporation and identified associated predisposing factors using CT scan.

Aims

This study reports updates the previously published two-year clinical, functional, and radiological results of a group of patients who underwent transfibular total ankle arthroplasty (TAA), with follow-up extended to a minimum of five years.

The precise localisation of osteoarthritic changes is crucial for selective surgical treatment. Single photon-emission CT-CT (SPECT-CT) combines both morphological and biological information. We hypothesised that SPECT-CT increased the intra- and interobserver reliability to localise increased uptake compared with traditional evaluation of CT and bone scanning together. We evaluated 20 consecutive patients with pain of uncertain origin in the foot and ankle by radiography and SPECT-CT, available as fused SPECT-CT, and by separate bone scanning and CT. Five observers assessed the presence or absence of arthritis. The images were blinded and randomly ordered. They were evaluated twice at an interval of six weeks. Kappa and multirater kappa values were calculated. The mean intraobserver reliability for SPECT-CT was excellent (κ = 0.86; 95% CI 0.81 to 0.88) and significantly higher than that for CT and bone scanning together. SPECT-CT had significantly higher interobserver agreement, especially when evaluating the naviculocuneiform and tarsometatarsal joints. SPECT-CT is useful in localising active arthritis especially in areas where the number and configuration of joints are complex

The Bologna–Oxford (BOX) total ankle replacement (TAR) was developed with the aim of achieving satisfactory pain-free movement of the ankle. To date, only one single multicentre study has reported its clinical results. The aim of this study was to conduct an independent review of its mid-term results. We retrospectively reviewed a total of 60 prospectively followed patients in whom 62 BOX TARs had been implanted between 2004 and 2008. We used the American Orthopedic Foot and Ankle Society (AOFAS) score to assess the clinical results. Standardised radiographs taken at the time of final follow-up were analysed by two observers. The overall survival was 91.9% at a mean follow-up of 42.5 months (24 to 71). The mean AOFAS score had improved from 35.1 points (. sd. 16.6; 4 to 73) pre-operatively to 78.0 (. sd. 10.7; 57 to 100) at final follow-up (p < 0.01). Tibial radiolucencies < 2 mm in width were seen around 16 TARs. Talar radiolucencies < 2 mm were seen around four TARs. A total of 47 patients (78.3%) were very satisfied or satisfied with the outcome. Five patients required revision for functional limitation or continuing pain

Aims

Arthroplasty has become increasingly popular to treat end-stage ankle arthritis. Iatrogenic posterior neurovascular and tendinous injury have been described from saw cuts. However, it is hypothesized that posterior ankle structures could be damaged by inserting tibial guide pins too deeply and be a potential cause of residual hindfoot pain.

Between 2002 and 2008, 130 consecutive ankles were replaced with an hydroxyapatite (HA) and titanium-HA-coated Ankle Evolutive System total ankle prosthesis. Plain radiographs were analysed by two independent observers. Osteolytic lesions were classified by their size and location, with cavities > 10 mm in diameter considered to be ‘marked’. CT scanning was undertaken in all patients with marked osteolysis seen on the plain radiographs. Osteolytic lesions were seen on the plain films in 48 (37%) and marked lesions in 27 (21%) ankles. The risk for osteolysis was found to be 3.1 (95% confidence interval 1.6 to 5.9) times higher with implants with Ti-HA porous coating. Care should be taken with ankle arthroplasty until more is known about the reasons for these severe osteolyses

Aims

The morphology of medial malleolar fracture is highly variable and difficult to characterize without 3D reconstruction. There is also no universally accepeted classification system. Thus, we aimed to characterize fracture patterns of the medial malleolus and propose a classification scheme based on 3D CT reconstruction.

Introduction:. Fibular malreduction is a common and important cause of pain after surgical fixation following a syndesmosis injury, but it is unclear which components of malreduction correspond to clinical outcome. Plain radiographs have been shown to be unreliable at measuring malreduction when compared to CT scans. A number of published methods for measuring fibular position rely on finding the axis of the fibula. Elgafy demonstrated that fibular morphology varies greatly, and some studies have demonstrated difficulty finding the fibular axis. Methods:. We developed a new method of measuring the distal fibular position on CT images. We used CT studies in 16 normal subjects. Two assessors independently measured the ankle syndesmosis using the Davidovitch method, and our new protocol for fibular AP position, diastasis and fibular length. Results:. We demonstrated that after statistical analysis (Pearson Product Moment Correlation) our method showed improved inter-observer reliability (r = 0.99 and 0.95 vs 0.59 and 0.78 respectively) for diastasis and AP translation, and improved intra-observer reliability (r = 0.99 and 0.99 vs 0.91 and 0.97 respectively). We found inter and intra observer reliability of 0.80 and 0.91 respectively for fibular length, but were unable to find a novel, accurate method for measuring fibular rotation. Conclusions:. Our method is a new, simple, accurate and reproducible system for measuring the ankle syndesmosis. We believe that this method could be used to assess fibular reduction after obtaining CT images of the uninjured side for comparison

Aims

In the context of tendon degenerative disorders, the need for innovative conservative treatments that can improve the intrinsic healing potential of tendon tissue is progressively increasing. In this study, the role of pulsed electromagnetic fields (PEMFs) in improving the tendon healing process was evaluated in a rat model of collagenase-induced Achilles tendinopathy.

Informed consent is integral to good-practice. It protects the patient and offers proof of discussion and interaction between the surgeon and the patient. We compare efficacy of last clinic consent, specialised consent clinic with or without provision of patient specific literature. Group A patients underwent written consent at their last outpatient clinic and conformation of consent on the morning of surgery. Group B underwent consent in designated pre-admission clinic in the week prior to surgery. Group (C) attended the same preadmission clinic and were provided with a surgeon dictated written explanation of their surgery and particular risks. This included a explanation of the procedure, complications, risks and rewards in layman's terms, aimed at patients with a reading age of 14 years, with advice concerning alternative procedures and the consequences of taking no action. The risks are graded: common, less common and rare. All patients undertook a pre-surgery questionnaire on the morning of surgery by an independent observer prior to any contact with the surgical team. Questions focused on their planed procedure, post-operative instructions and possible complications in order to assess the recall of the consent process. A VAS-scale was added to assess overall satisfaction. Statistical analysis was undertaken by a T-test. In total 162-patients were assessed, the response rate was 68.5% (n=111). In-group A (n=16) 18.8% patients remembered 3 relevant complications, 56.2% recalled their post-operative considerations their overall satisfaction was 4/10. In-group B (n=57) 45.5% remembered three complications, 63.7% recalled their postoperative considerations and had a patient satisfaction of 5/10. In-group C (n=38) 48.3% remembered three complications, and 70.7% recalled postoperative considerations, the overall satisfaction improved to 6/10. We observed that the consent process is improved by the use of routine pre-operative consent clinics; however the addition of patient specific literature is observed to further improve recall and satisfaction

Body Image is defined as our internalised sense of what we look like. For most of us, there is a relatively good match between what we think we look like and how we appear to other people. Body image can also be studied in terms of what you look like in the eyes of an observer and the pressures that occur to look a certain way. Body Dysmorphic Disorder (BDD) is the most extreme type of body image problem and consists of a preoccupation with one or more features that is not noticeable to others or the person's concern is markedly excessive. The preoccupation is associated with many time consuming rituals such as mirror gazing or constant comparing. It is associated with a poor quality of life, social isolation, depression and a high risk of committing suicide. Any part of the body may be involved but the foot is an uncommon focus for people with BDD. Such individuals often have needless dermatological treatment and cosmetic surgery. Body image problems and especially BDD is easily trivialised and stigmatised. People with BDD can benefit from cognitive behaviour therapy and certain types of medication. Speaker.

Aims

The purpose of this study was to determine the functional outcome and implant survivorship of mobile-bearing total ankle arthroplasty (TAA) performed by a single surgeon.

Aims

The aims of this study were to evaluate the morphology of the ankle in patients with an osteochondral lesion of the talus using 3D CT, and to investigate factors that predispose to this condition.

Aims

Fractures of the navicular can occur in isolation but, owing to the intimate anatomical and biomechanical relationships, are often associated with other injuries to the neighbouring bones and joints in the foot. As a result, they can lead to long-term morbidity and poor function. Our aim in this study was to identify patterns of injury in a new classification system of traumatic fractures of the navicular, with consideration being given to the commonly associated injuries to the midfoot.

Aims

Morton’s neuroma is common condition of the forefoot, but its aetiology remains unclear. Our aim was to evaluate the relationship between the width of the forefoot and the development of a Morton’s neuroma.

In this retrospective cohort study, we analysed the incidence and functional outcome of a distal tibiofibular synostosis. Patients with an isolated AO type 44-B or C fracture of the ankle who underwent surgical treatment between 1995 and 2007 were invited for clinical and radiological review. The American Orthopaedic Foot and Ankle Society score, the American Academy of Orthopaedic Surgeons score and a visual analogue score for pain were used to assess outcome.

A total of 274 patients were available; the mean follow-up was 9.7 years (8 to 18). The extent of any calcification or synostosis at the level of the distal interosseous membrane or syndesmosis on the contemporary radiographs was defined as: no or minor calcifications (group 1), severe calcification (group 2), or complete synostosis (group 3).

A total of 222 (81%) patients were in group 1, 37 (14%) in group 2 and 15 (5%) in group 3. There was no significant difference in incidence between AO type 44-B and type 44-C fractures (p = 0.89). Severe calcification or synostosis occurred in 21 patients (19%) in whom a syndesmotic screw was used and in 31 (19%) in whom a syndesmotic screw was not used.(p = 0.70). No significant differences were found between the groups except for a greater reduction in mean dorsiflexion in group 2 (p = 0.004).

This is the largest study on distal tibiofibular synostosis, and we found that a synostosis is a frequent complication of surgery for a fracture of the ankle. Although it theoretically impairs the range of movement of the ankle, it did not affect the outcome.

Our findings suggest that synostosis of the distal tibiofibular syndesmosis in general does not warrant treatment.

Large osteochondral lesions (OCLs) of the shoulder of the talus cannot always be treated by traditional osteochondral autograft techniques because of their size, articular geometry and loss of an articular buttress. We hypothesised that they could be treated by transplantation of a vascularised corticoperiosteal graft from the ipsilateral medial femoral condyle.

Between 2004 and 2011, we carried out a prospective study of a consecutive series of 14 patients (five women, nine men; mean age 34.8 years, 20 to 54) who were treated for an OCL with a vascularised bone graft. Clinical outcome was assessed using a visual analogue scale (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score. Radiological follow-up used plain radiographs and CT scans to assess graft incorporation and joint deterioration.

At a mean follow-up of 4.1 years (2 to 7), the mean VAS for pain had decreased from 5.8 (5 to 8) to 1.8 (0 to 4) (p = 0.001) and the mean AOFAS hindfoot score had increased from 65 (41 to 70) to 81 (54 to 92) (p = 0.003). Radiologically, the talar contour had been successfully reconstructed with stable incorporation of the vascularised corticoperiosteal graft in all patients. Joint degeneration was only seen in one ankle.

Treatment of a large OCL of the shoulder of the talus with a vascularised corticoperiosteal graft taken from the medial condyle of the femur was found to be a safe, reliable method of restoring the contour of the talus in the early to mid-term.

The foot and ankle outcome score (FAOS) has been evaluated for many conditions of the foot and ankle. We evaluated its construct validity in 136 patients with osteoarthritis of the ankle, its content validity in 37 patients and its responsiveness in 39. Data were collected prospectively from the registry of patients at our institution.

All FAOS subscales were rated relevant by patients. The Pain, Activities of Daily Living, and Quality of Life subscales showed good correlation with the Physical Component score of the Short-Form-12v2. All subscales except Symptoms were responsive to change after surgery.

We concluded that the FAOS is a weak instrument for evaluating osteoarthritis of the ankle. However, some of the FAOS subscales have relative strengths that allow for its limited use while we continue to seek other satisfactory outcome instruments.
