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. Arthroscopically controlled fracture reduction in combination with percutaneous screw fixation may be an alternative approach to open surgery to treat talar neck fractures. The purpose of this study was thus to present preliminary results on arthroscopically reduced talar neck fractures. Patients and Methods. A total of seven consecutive patients (four women and three men, mean age 39 years (19 to 61)) underwent attempted surgical treatment of a closed Hawkins type II talar neck fracture using arthroscopically assisted reduction and percutaneous screw fixation. Functional and radiological outcome were assessed using plain radiographs, as well as weight-bearing and non-weight-bearing CT scans as tolerated. Patient satisfaction and pain sensation were also recorded. Results. Primary reduction was obtained arthroscopically in all but one patient, for whom an interposed fracture fragment had to be removed through a small arthrotomy to permit anatomical reduction. The quality of arthroscopic reduction and restoration of the talar geometry was excellent in the remaining six patients. There were no signs of talar avascular necrosis or subtalar degeneration in any of the patients. In the whole series, the functional outcome was excellent in five patients but restricted ankle movement was observed in two patients. All patients had a reduction in subtalar movement. At final follow-up, all patients were satisfied and all but one patient were pain free. Conclusion. Arthroscopically assisted reduction and fixation of talar neck fractures was found to be a feasible treatment option and allowed early functional rehabilitation.

Introduction. Greater length of stay (LOS) after elective surgery results in increased use of health care resources and higher costs. Within the realm of foot and ankle surgery, improved perioperative care has enabled a vast majority of procedures to be performed as a day surgery. The objective of this study was to determine the perioperative factors that predict a prolonged LOS after elective ankle replacement or fusion. Methods. Data was prospectively collected on patients undergoing either an ankle fusion or ankle replacement for end-stage ankle arthritis at our institution (2003–2010). In the analysis, LOS was the outcome and age, sex, physical and mental functional scores, comorbid factors, ASA grades, type and length of operation and body mass index (BMI) were potential perioperative risk factors. Univariate and multivariate generalized linear regression models with gamma distribution and log link function were conducted. Results. A total of 336 patients were included in the study. The median LOS was 76 hours with interquartile range of 52.5–97. Using regression analysis, we showed aging, female gender, a higher ASA score, multiple medical comorbidities, rheumatoid arthritis, a lower score in the physical component (PCS) and general health domain (GH) of SF-36, open surgery and an increased length of surgical time were all significantly associated with an increased LOS. Conversely, obesity, the SF-36 Mental Component Score and the date of admission were noninfluential of LOS. A predictive model was also developed using these same risk factors. Conclusions. Increased age, female gender, high ASA scores, low SF-36 GH and PCS scores, increased number of medical comorbidities, rheumatoid arthritis and open surgery were all factors that increased LOS significantly after ankle fusion or ankle replacement. This group of patients may warrant better education and more focused perioperative care when it comes to designing care pathways and allocating health care resources

Lisfranc fracture dislocations of the midfoot are uncommon but serious injuries, associated with posttraumatic arthrosis, progressive deformity, and persistent pain. Management of the acute injury aims to restore anatomic tarsometatarsal alignment in order to minimise these complications. Reduction and stabilisation can be performed using image-guided percutaneous reduction and screw stabilisation (aiming to minimise the risk of wound infection) or through open plating techniques (in order to visualise anatomic reduction, and to avoid chondral damage from transarticular screws). This retrospective study compares percutaneous and open treatment in terms of radiographic reduction and incidence of early complications. Case records and postoperative radiographs of all patients undergoing reduction and stabilisation of unstable tarsometatarsal joint injuries between 2011 and 2014 in our institution were reviewed. Dorsoplantar, oblique and lateral radiographs were assessed for accuracy of reduction, with malreduction being defined as greater than 2mm tarsometatarsal malalignment in any view. The primary outcome measure was postoperative radiographic alignment. Secondary outcome measures included the incidence of infection and other intra- or early postoperative complications. During the study period, 32 unstable midfoot injuries were treated, of which 19 underwent percutaneous reduction and screw stabilisation and 13 underwent open reduction and internal fixation. Of the percutaneous group, no wound infections were reported, and there were four (21.1%) malreduced injuries. Of the open group, two infections (15.4%) were observed, and no cases of malreduction. In conclusion, our study shows a strong trend towards increased risk of malreduction when percutaneous techniques are used to treat midfoot injuries, and an increased risk of infection when open surgery is used. Whilst conclusions are limited by the retrospective data collection, this study demonstrates the relative risks to consider when selecting a surgical approach

Aims

A pilon fracture is a severe ankle joint injury caused by high-energy trauma, typically affecting men of working age. Although relatively uncommon (5% to 7% of all tibial fractures), this injury causes among the worst functional and health outcomes of any skeletal injury, with a high risk of serious complications and long-term disability, and with devastating consequences on patients’ quality of life and financial prospects. Robust evidence to guide treatment is currently lacking. This study aims to evaluate the clinical and cost-effectiveness of two surgical interventions that are most commonly used to treat pilon fractures.

Aims

The primary objective was to determine the incidence of COVID-19 infection and 30-day mortality in patients undergoing foot and ankle surgery during the global pandemic. Secondary objectives were to determine if there was a change in infection and complication profile with changes introduced in practice.

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

Persistent pain is a common cause of disability in patients after fractures of the calcaneum. Amongst the possible causes for post traumatic pain is the development of degenerative osteoarthritis of the posterior facet of the subtalar joint. However there are many other causes of post-traumatic hindfoot pain which require consideration prior to treatment. Knowledge of the patho-anatomy of calcaneal fractures is required to reach an accurate diagnosis. Significant symptoms and disability may be treated by arthrodesis of the subtalar joint. Post-traumatic arthritis in the non-operatively treated calcaneal fracture is however usually associated with deformity of the hindfoot, disordered hindfoot biomechanics, lateral wall fibular impingement and fibular tendon dysfunction. Fractures treated by primary open reduction and fixation should be well aligned but despite anatomic reduction may also develop posterior facet arthritis. Symptoms may also be caused by prominence or impingement of the implant, particularly of locked perimeter plates on the lateral wall. Patients therefore require careful assessment prior to surgery and any operative measures have to address these key features in order to produce a satisfactory clinical result. This lecture will address the potential problems of this type of surgery and key features in the clinical assessment and imaging of these patients. Subtalar arthrodesis in the presence of deformity is technically complex and requires careful planning in order to correct the deformity and to produce a well aligned hindfoot to allow corrected biomechanics without impingement and the fitment of suitable footwear. The surgical techniques and different types of surgery required to adequately manage the posterior facet and deformity will be covered and will include arthroscopically assisted in-situ fusion, the safe approaches for open surgery and techniques to reconstruct the lateral wall, fibular tendon function and osteotomies required to restore calcaneal height and alignment

Introduction. We describe our experience with a minimally invasive Chevron and Akin (MICA) technique for hallux valgus correction. This technique adheres to the same principles as open surgical correction but is performed using a specialized high-speed cutting burr under image intensifier guidance via tiny skin portals. Methods. All patients undergoing minimally invasive hallux valgus correction between November 2009 and April 2010 were included in this study and were subject to prospective clinical and radiological review. Patients were scored using the Kitaoka score as well as radiological review and patient satisfaction survey. Surgery was performed under general anaesthetic and included distal soft tissue release, Chevron and Akin osteotomies, with the same indications as for open surgery. All osteotomies were internally fixed with cannulated compression screws. Results. 83 operations were performed on 70 patients (2 male 65 female, mean age 54 years (27-78)). The pre-operative mean HVA was 34° and IMA 14°. Post-operative mean HVA was 9° and IMA 9.5°. Kitaoka score improved significantly at 3-12 months follow-up. There were no delayed or non- s and no osteonecrosis. Six M1 osteotomies moved during the postoperative period (3 feet (2 patients) required further surgery + 3 incomplete corrections without need for further surgery) and the fixation technique was successfully modified to avoid this problem. Mild transfer metatarsalgia was observed in 4 patients. There were 2 superficial wound infections. Cutaneous nerve injuries were noted in 3 feet but none painful. No recurrent deformities observed to date. Overall, 65% patients very satisfied, 29% satisfied, 6% unsatisfied. Discussion. This study suggests that good results can be obtained in forefoot surgery with the MICA technique. We believe this technique may offer advantages for some patients in terms of reduced morbidity and cosmesis. A randomized study is in progress to compare open and minimally invasive techniques

Manipulation of the metatarsophalangeal joint and injection with steroid and local anaesthetic are widely practised in the treatment of hallux rigidus, but there is little information on the outcome. We report the results of this procedure carried out on 37 joints, with a minimum follow-up of one year (mean, 41.2 months). Patients with mild (grade-1) changes gained symptomatic relief for a median of six months and only one-third required surgery. Two-thirds of patients with moderate (grade-2) disease proceeded to open surgery. In advanced (grade-III) hallux rigidus, little symptomatic relief was obtained and all patients required operative treatment. We recommend that joints are graded before treatment and that manipulation under anaesthetic and injection be used only in early (grades I and II) hallux rigidus

Introduction. Scar sensitivity is a recognised complication of foot surgery. However there is very little published about it. This study looks at the incidence and natural history of scar sensitivity following hallux valgus surgery. Materials and Methods. Patients who had open hallux valgus surgery from December 2008 to December 2009, with a minimum follow up of 12 months, were contacted. Data regarding scar symptoms, their duration, severity at their worst and interventions undertaken were collected. Patients also completed a Roles and Maudsley patient satisfaction score. Results. 125 patients were contacted with response rate of 84%. 30% of patients had experienced scar symptoms following surgery. Of these, 20% had undertaken some form of nonsurgical intervention. The mean duration of symptoms was 16 weeks, and 95% of patients experienced resolution of symptoms. 99% of patients would opt to have the surgery again. Roles and Maudsley score ranged from 1 to 2. Discussion. Nearly one third of patients experienced scar symptoms, however nearly all resolved completely with or without simple treatments. Symptoms were not severe and did not affect satisfaction, function or the decision to have the surgery again. Educating patients preoperatively about scar sensitivity can relieve anxiety and improve the patient experience and they can be advised on simple and effective strategies should this common side effect occur. The results of this study provide the surgeon with valuable information in the consent and education of patients. Also, the fact that nearly all symptom settled within 16 weeks brings into question one of the purported advantages of minimally invasive surgery. Conclusion. Scar symptoms following hallux valgus surgery are common, but mild and almost all resolve in time
