Aim. Our collaborative study aims to demonstrate that acute partial Achilles Tendon Tears (ATTs) are not separate diagnostic entities from full ATTs. and should be thought of as a continuum rather than binary partial or full. Methods. We pooled anonymised data from four hospitals, identifying patients with acute partial ATTs on USS reports from 2019–2021. Patients were only included if they had an acute injury and no previous background Achilles tendinopathy. Results. 91 patients had acute partial ATTs reported on USS. 74/91 (81%) of patients had clinical findings in keeping with a full ATT (positive Simmonds test, palpable gap). 88/91 (97%) of patients were managed according to local full ATT protocols. 2 patients had MRIs – one showed no tear, the other showed a full rupture. 2 patients underwent surgical repair and both intra-operatively were found to have full ATTs. Conclusion. Our regional data suggests that a significant proportion (81%) of USS diagnosed partial ATTs may in fact be misdiagnosed full ATTs. All injuries clinically suspicious for an ATT should be managed according to local Achilles Protocol. USS is useful to diagnose the presence or absence of a tear but is not good at differentiating partial vs full tear. There is significant tendon end fibrillation and overlap on USS of an acute full ATT, which can give the impression of a partial ATT. More research is needed into whether any threshold exists to support the current distinction of “partial” and “full” as relates to management and outcomes

Background. Weightbearing computed tomography scans allow for better understanding of foot alignment in patients with Progressive Collapsing Foot Deformity. However, soft tissue integrity cannot be assessed via WBCT. As performing both WBCT and magnetic resonance imaging is not cost effective, we aimed to assess whether there is an association between specific WBCT and MRI findings. Methods. A cohort of 24 patients of various stages of PCFD (mean age 51±18 years) underwent WBCT scans and MRI. In addition to signs of sinus tarsi impingement, four three-dimensional measurements (talo-calcaneal overlap, talo-navicular coverage, Meary's angle axial/lateral) were obtained using a post processing software (DISIOR 2.1, Finland) on the WBCT datasets. Sinus tarsi obliteration, spring ligament complex and tibiospring ligament integrity, as well as tibialis posterior tendon degeneration were evaluated with MRI. Statistical analysis was performed for significant (P<0.05) correlation between findings. Results. None of the assessed 3D measurements correlated with spring ligament complex or tibiospring ligament tears. Age, body mass index, and TCO were associated with tibialis posterior tendon tears. 75% of patients with sinus tarsi impingement on WBCT also showed signs of sinus tarsi obliteration on MRI. Of the assessed parameters, only age and BMI were associated with sinus tarsi obliteration diagnosed on MRI, while the assessed WBCT based 3D measurements were, with the exception of MA axial, associated with sinus tarsi impingement. Conclusion. While WBCT reflects foot alignment and indicates signs of osseous impingement in PCFD patients, the association between WBCT based 3D measurements and ligament or tendon tears in MRI is limited. Partial or complete tears of the tibialis posterior tendon were only detectable in comparably older and overweight PCFD patients with an increased TCO. WBCT does not replace MRI in diagnostic value. Both imaging options add important information and may impact decision-making in the treatment of PCFD patients

Background. Lisfranc fracture dislocations are uncommon injuries, which frequently require surgical intervention. Currently, there is varying evidence on the diagnostic utility of plain radiographs (XR) and CT in identifying Lisfranc injuries and concomitant fractures. Our aim was to identify the utility of XR as compared to CT, with the nul hypothesis that there was no difference in fracture identification. Methods. A retrospective assessment of patients who had sustained a Lisfranc injury between 2013 and 2022 across two trauma centres within the United Kingdom who underwent surgery. Pre-operative XR and CT images were reviewed independently by 2 reviewers to identify the presence of associated fractures. Results. A total of 175 patients were included. Our assessment identified that XR images significantly under-diagnosed all metatarsal and midfoot fractures. The largest discrepancies between XR and CT in their rates of detection were in fractures of the cuboid (5.7% vs 28%, p<0.001), medial cuneiform (20% vs 51%, p=0.008), lateral cuneiform (4% vs 36%, p=0.113), second metatarsal (57% vs 82%, p<0.001), third metatarsal (37% vs 61%, p<0.001) and fourth metatarsal (26% vs 43%, p<0.001). As compared to CT, the sensitivity of XR was low. The lowest sensitivity for identification however was lateral foot injuries, specifically fractures of the lateral cuneiform (sensitivity 7.94%, specificity 97.3%), cuboid (sensitivity 18.37%, specificity 99.21%), fourth (sensitivity 46.7%, specificity 89.80%) and fifth metatarsal (sensitivity 45.00%, specificity 96.10%). Conclusion. From our analysis, we can determine that XR significantly under-diagnoses associated injuries in patient sustaining an unstable Lisfranc injury, with lateral foot injuries being the worst identified. We advised the use of CT imaging in all cases for appropriate surgical planning

Aims

Achilles tendon re-rupture (ATRR) poses a significant risk of postoperative complication, even after a successful initial surgical repair. This study aimed to identify risk factors associated with Achilles tendon re-rupture following operative fixation.

Aims

The aim of this study was to capture 12-month outcomes from a representative multicentre cohort of patients undergoing total ankle arthroplasty (TAA), describe the pattern of patient-reported outcome measures (PROMs) at 12 months, and identify predictors of these outcome measures.

Aims

To describe outcome reporting variation and trends in non-pharmacological randomized clinical trials (RCTs) of distal tibia and/or ankle fractures.

The last decade has seen a considerable increase in the use of in total ankle arthroplasty (TAA) to treat patients with end-stage arthritis of the ankle. However, the longevity of the implants is still far from that of total knee and hip arthroplasties. . The aim of this review is to outline a diagnostic and treatment algorithm for the painful TAA to be used when considering revision surgery. Cite this article: Bone Joint J 2017;99-B:5–11

Charcot neuroarthropathy is a rare but serious complication of diabetes, causing progressive destruction of the bones and joints of the foot leading to deformity, altered biomechanics and an increased risk of ulceration. Management is complicated by a lack of consensus on diagnostic criteria and an incomplete understanding of the pathogenesis. In this review, we consider recent insights into the development of Charcot neuroarthropathy. It is likely to be dependent on several interrelated factors which may include a genetic pre-disposition in combination with diabetic neuropathy. This leads to decreased neuropeptides (nitric oxide and calcitonin gene-related peptide), which may affect the normal coupling of bone formation and resorption, and increased levels of Receptor activator of nuclear factor kappa-B ligand, potentiating osteoclastogenesis. Repetitive unrecognized trauma due to neuropathy increases levels of pro-inflammatory cytokines (interleukin-1β, interleukin-6, tumour necrosis factor α) which could also contribute to increased bone resorption, in combination with a pre-inflammatory state, with increased autoimmune reactivity and a profile of monocytes primed to transform into osteoclasts - cluster of differentiation 14 (CD14). Increased blood glucose and loss of circulating Receptor for Advanced Glycation End-Products (AGLEPs), leading to increased non-enzymatic glycation of collagen and accumulation of AGLEPs in the tissues of the foot, may also contribute to the pathological process. An understanding of the relative contributions of each of these mechanisms and a final common pathway for the development of Charcot neuroarthropathy are still lacking. Cite this article: S. E.

Aims

To assess the characteristic clinical features, management, and outcome of patients who present to orthopaedic surgeons with functional dystonia affecting the foot and ankle.

We present a review of litigation claims relating to foot and ankle surgery in the NHS in England during the 17-year period between 1995 and 2012. A freedom of information request was made to obtain data from the NHS litigation authority (NHSLA) relating to orthopaedic claims, and the foot and ankle claims were reviewed. . During this period of time, a total of 10 273 orthopaedic claims were made, of which 1294 (12.6%) were related to the foot and ankle. 1036 were closed, which comprised of 1104 specific complaints. Analysis was performed using the complaints as the denominator. The cost of settling these claims was more than £36 million. . There were 372 complaints (33.7%) involving the ankle, of which 273 (73.4%) were related to trauma. Conditions affecting the first ray accounted for 236 (21.4%), of which 232 (98.3%) concerned elective practice. Overall, claims due to diagnostic errors accounted for 210 (19.0%) complaints, 208 (18.8%) from alleged incompetent surgery and 149 (13.5%) from alleged mismanagement. . Our findings show that the incorrect, delayed or missed diagnosis of conditions affecting the foot and ankle is a key area for improvement, especially in trauma practice.

Introduction. Chronic mid body Achilles tendinopathy is a common problem. There is no consensus on treatment. The aim of this review was to assess the effectiveness of physiotherapy interventions (non surgical and non pharmacological) for this condition. Methods. A systematic review of the literature was conducted. A search of published and grey literature databases was undertaken (1999- December 2010). Two reviewers independently assessed the studies for eligibility using a strict inclusion and exclusion criteria. All eligible articles were assessed critically using the Pedro score. Data on cohort characteristics, diagnostic criteria, treatment intervention, outcome measures and results was extracted. A narrative research synthesis method was adopted. Results. 209 studies were identified. Nine publications met the review inclusion criteria. Methodological quality was adequate for all nine studies; however, blinding was a limitation for most. Interventions investigated were; Exercises (n = 2), Low level laser therapy (n = 1), Low energy shockwave treatment (SWT) (n = 3), Air cast brace (n = 2) and Insoles (n = 1). Some evidence exists for eccentric exercises in combination with SWT or Laser. However, contrary to other reviews, eccentric exercises were not found to be superior to other physiotherapy treatments. Conclusions. There is insufficient evidence to determine which method of physiotherapy is most appropriate for a chronic Achilles tendinopathy. Further well designed randomised controlled trials assessing physiotherapy interventions with specific diagnostic criteria and appropriate outcome tools are required to determine the efficacy of physiotherapy for the condition

Diagnostic and operative codes are routinely collected for every patient admitted to hospital in the English NHS. Data on post-operative complications following foot and ankle surgery have not previously been available in large numbers. Data on symptomatic venous thromboembolism events and mortality within 90 days were extracted for patients undergoing fixation of an ankle fracture, first metatarsal osteotomy, hindfoot fusions and total ankle replacement over a period of 42 months. For ankle fracture surgery (45 949 patients), the rates of deep-vein thrombosis (DVT), pulmonary embolism and mortality were 0.12%, 0.17% and 0.37%, respectively. For first metatarsal osteotomy (33 626 patients), DVT, pulmonary embolism and mortality rates were 0.01%, 0.02% and 0.04%, and for hindfoot fusions (7033 patients) the rates were 0.03%, 0.11% and 0.11%, respectively. The rate of pulmonary embolism in 1633 total ankle replacement patients was 0.06%, and there were no recorded DVTs and no deaths. Statistical analysis could only identify risk factors for venous thromboembolic events of increasing age and multiple comorbidities following fracture surgery. Venous thromboembolism following foot and ankle surgery is extremely rare, but this subset of fracture patients is at a higher risk. However, there is no evidence that thromboprophylaxis reduces this risk, and these national data suggest that prophylaxis is not required in most of these patients

Supination-external rotation (SER) fractures of the ankle may present with a medial ligamentous injury that is not apparent on the initial radiographs. A cadaver gravity-stress view has been described, but the manual-stress view is considered to be the examination of choice for the diagnosis of medial injuries. We prospectively compared the efficacy of these two examinations. We undertook both examinations in 29 patients with SER fractures. Of these, 16 (55%) were stress-positive, i.e. and had widening of the medial clear space of > 4 mm with a mean medial clear space of 6.09 mm (4.4 to 8.1) on gravity-stress and 5.81 mm (4.0 to 8.2) on manual-stress examination, and 13 patients (45%) were stress-negative with a mean medial clear space of 3.91 mm (3.3 to 5.1) and 3.61 mm (2.6 to 4.5) on examination of gravity- and manual-stress respectively. The mean absolute visual analgoue scale score for discomfort in the examination of gravity stress was 3.45 (1 to 6) and in the manual-stress procedure 6.14 (3 to 10). We have shown that examination of gravity-stress is as reliable and perceived as more comfortable than that of manual stress. We recommend using it as the initial diagnostic screening examination for the detection of occult medial ligamentous injuries in SER fractures of the ankle

Introduction:. Cone Based CT (CBCT) scanning uses a point source and a planar detector with parallel data acquisition and volumetric coverage of the area of interest. The pedCAT (Curvebeam USA) scanner is marketed as a low radiation dose, compact, faster and inexpensive CT scanner that can be used to obtain both non- weightbearing and true 3 dimensional weightbearing views. Method:. A review of the first 100 CBCT scanning in our unit has been performed to assess ease of scanning, imaging time, radiation dose and value of imaging as opposed to conventional imaging. Results:. A pedcat CT scan was available within minutes of the request, similar to plain radiographs but much earlier than a 6 week delay for a patient to attend a new appointment for a conventional CT. All patients returned to see the clinician for a clinical decision in the same NHS clinic and did not require a new clinic visit; illustrative cases include fracture/subluxation detection, surgical planning, extent of arthritis and 3D assessment of union of arthrodeses. All patients were able to transfer to the scanner with ease and the imaging time was 10 times than a conventional CT. The radiation dose to the patients was 9% that of a full gantry system. Weightbearing CT scanning enabled a 3D evaluation of reduction of joint space and ankle/hindfoot alignment. Anterior ankle and sesamoid impingement have been diagnosed in patients with previously obscure pain. Conclusion:. 3D Cone Beam imaging has been found to be easily accessible, rapidly performed and safer to the patient in providing a lower radiation dose. Weightbearing 3D imaging provides additional diagnostic information

Achilles tendinopathy is a common cause of disability. Despite the economic and social relevance of the problem, the causes and mechanisms of Achilles tendinopathy remain unclear. Tendon vascularity, gastrocnemius-soleus dysfunction, age, gender, body weight and height, pes cavus, and lateral ankle instability are considered common intrinsic factors. The essence of Achilles tendinopathy is a failed healing response, with haphazard proliferation of tenocytes, some evidence of degeneration in tendon cells and disruption of collagen fibres, and subsequent increase in non-collagenous matrix. Tendinopathic tendons have an increased rate of matrix remodelling, leading to a mechanically less stable tendon which is more susceptible to damage. The diagnosis of Achilles tendinopathy is mainly based on a careful history and detailed clinical examination. The latter remains the best diagnostic tool. Over the past few years, various new therapeutic options have been proposed for the management of Achilles tendinopathy. Despite the morbidity associated with Achilles tendinopathy, many of the therapeutic options described and in common use are far from scientifically based. New minimally invasive techniques of stripping of neovessels from the Kager's triangle of the tendo Achillis have been described, and seem to allow faster recovery and accelerated return to sports, rather than open surgery. A genetic component has been implicated in tendinopathies of the Achilles tendon, but these studies are still at their infancy

Painful peroneal spastic flatfeet without coalition or other known etiologies in adolescence, remains a difficult condition to treat. We present eight such cases with radiological and surgical evidence of bony abnormalities in the lateral subtalar region just anterior to the posterior facet. All patients had presented as tertiary referrals with recalcitrant pain and had undergone a trial of orthotics and physiotherapy. Diagnostic workup included a clinical and radiographic evaluation. Clinical examination consisted of gait examination, foot alignment, range of motion, torsional profile of the lower limbs and marking of symptomatic foci. All patients had standing weightbearing anteroposterior and lateral projections of the foot and ankle, CT and/or MRI scans of the foot. Coalitions and other known intra-articular pathologies like subtalar arthritis were ruled out. All patients had bilateral flatfeet but unilateral peroneal spasm. All patients had an accessory anterolateral talar facet (ATF) which was arising as an anterior and distal extension of the lateral process of the talus. This caused lateral impingement between the facet and the calcaneum, confirmed by bone edema around the sinus tarsi and marked at the apex of the angle of Gissane on MRI scans. All patients had stiff subtalar joints with very limited movement under anaesthesia, indicating peroneal muscle contracture. Patients were treated with a combination of facet excision, fractional peroneal and gastrosoleus lengthening and calcaneal lengthening to correct the flatfoot and prevent lateral impingement

Background. The recent emphasis on using “evidence based medicine” for decision-making in patient care has prompted many publishers to mention the level of evidence of articles in their journals. The “quality” of a journal may thus be reflected by the proportion of articles with high levels of evidence and assist it achieve citations and therefore an Impact Factor. The purpose of this study was to survey published Foot and Ankle literature to evaluate changes in the level of evidence over ten years. Methods. Articles from Foot and Ankle International, JBJS Br, JBJS Am, Foot and Foot and Ankle Surgery were used. We looked at the years 2000 and 2010 and ranked the articles by a five-point level of evidence scale, according to guidelines from the Centre for Evidence Based Medicine. 498 articles were ranked. Studies of animals, studies of cadavera, basic-science articles were excluded. Results. For both years 2000 and 2010 combined, 63.5% of the articles were therapeutic, 25.5% were prognostic, 10.6% were diagnostic, and 0.8% were economic. In 2000 the ratings were 1.3% as Level I, 5.8% as Level II, 11.9% as Level III, 44.7% as Level IV and 36.3% as level V. In 2010 the ratings were 2.9% as Level I, 9.6% as Level II, 15.4% as Level III, 38.2% as Level IV and 33.8% as level V. Conclusion. The literature in foot and ankle surgery has responded to the demand for more evidence-based medicine with an increase in level I and II papers but the rate of change has been slow. The majority of evidence remains in the level IV and V

Introduction. This project reports differences in outcome measures after total ankle arthroplasty (TAA) for patients with Osteoarthritis (OA), Rheumatoid Arthritis (RA) and Post-traumatic Osteoarthritis (PTOA). Materials and Methods. Patients who underwent TAA between March 2006 and May 2010 were included. Assessments including questionnaires (height, weight, Foot and Ankle Outcome Score, SF-36) and American Orthopaedic Foot and Ankle Score (AOFAS) were completed pre-operatively, 3, 6, and 12-months after surgery. Analyses of outcomes by diagnosis were adjusted for age, gender and BMI. Results. A total of 114 TAAs performed for OA (59), PTOA (35), and RA (20). OA patients were significantly older than PTOA (64 vs. 56, p=0.002) and more likely to be male than either RA or PTOA (78% vs. 35% and 54%, p=0.001). PTOA and OA patients had significantly higher BMI (30 and 29) than RA (25, p=0.002). There were significant improvements at 12-months for AOFAS scores for all groups 31 to 75 (OA), 29 to 77 (PTOA) and 24 to 80 (RA). No significant difference in AOFAS scores between the groups at any time. Despite no significant difference in preoperative patient-reported measures between groups, OA patients reported worse ankle-related pain and function outcomes compared to the RA and PTOA patients. This trend increases at each follow-up period and was significant at 1-year for pain (p=0.03) and function (p=0.018). PTOA patients had significantly better SF-36 scores at 1 year (p<0.05 for 5 domains). Conclusion. These early results comparing outcomes by diagnostic groups demonstrate that PTOA and RA patients have superior outcomes compared to patients with primary OA

Ankle sprains in the athlete are one of the most common injuries, and syndesmosis type sprains seem to becoming diagnosed at an increasing rate. There still exists a paucity of information on optimal conservative and operative management. Treatment. Because of the spectrum of injury, there is a spectrum of treatment. if there is mortise widening, operative stabilization is required. if the mortise is normal, even with external rotation stress test positive, conservative treatment has been employed. staged conservative regimen directed at reducing pain and swelling acutely, at regaining range of motion and strength subacutely, and then progressed to functional training and finally return to sport. The timeframe for these was in the range of 2 to 6 weeks without very specific progression criteria. In the athlete, pain with rotational stress, greater severity of sprain, may treat operatively to stabilize the syndesmosis and aggressive rehab with earlier return to sport. Tightrope vs screw fixation vs both. Use of arthroscopy. Chronic sprains with recalcitrant pain and functional instability usually require operative treatment. very poor evidence exists as to the timing or type of procedure. Arthroscopy is required to confirm the diagnosis, treat intraarticular problems, and provide fixation of the distal tibiofibular syndesmosis. The postoperative regimen used is generally the same as the one used when treating an acute syndesmosis disruption. Tight rope vs Screw Fixation. clinical studies tightrope fixation has been acceptable and comparable to screw fixation. laboratory studies demonstrate comparable construct stability in the laboratory/cadaveric setting. indications for tightrope fixation are becoming more clear with more experience. my indications:. syndesmotic sprains with complete or incomplete disruption. fractures with syndesmotic disruption augment with screws, leave in place following screw removal. Summary and Controversies. Syndesmotic or high ankle sprains continue to be a common injury that result in significant time lost from sport. The conclusion that can be drawn from the current evidence is that the current diagnostic process probably fails to clearly assess the severity of the injury, which reduces the likelihood of accurately predicting the time lost from sport. Syndesmosis sprains can be a significant injuries that result in an inability to play sports for significant periods of time(up to 137 days). We need to be able to identify the more severe ones earlier in order to improve their treatment, perhaps lead to operative stabilization. Tightrope fixation avoids screw removal, minimally invasive, permanent stabilization

Aims

This paper documents the epidemiology of adults (aged more than 18 years) with a calcaneal fracture who have been admitted to hospital in England since 2000. Secondary aims were to document whether publication of the United Kingdom Heel Fracture Trial (UK HeFT) influenced the proportion of patients admitted to hospital with a calcaneal fracture who underwent surgical treatment, and to determine whether there has been any recent change in the surgical technique used for these injuries.
