Lower-extremity orthopaedic procedures may be performed under either regional or general anaesthesia, or a combination of both techniques. There is a growing body of evidence supporting the benefits of regional anaesthesia, with meta-analyses of randomised controlled trials and registry data suggesting decreases in deep surgical site infections, thromboembolic events, cardiopulmonary complications and length of stay associated with use of regional anaesthesia. In patients undergoing foot and ankle surgery specifically, there is evidence demonstrating decreased post-operative pain, nausea, vomiting, opioid use and unplanned hospital admission. This supports an increased role for the use in regional anaesthesia in patients undergoing foot and ankle surgery. However, the type of anaesthetic used is dependent on surgeon, patient, anaesthesiologist and institutional factors. The purpose of this study is to investigate pre-operative factors that predict the type of anaesthetic used in patients undergoing foot and ankle surgery. Data was collected prospectively on 888 patients undergoing foot or ankle surgery at a single institution. The primary method of anaesthesia for each procedure was recorded. Ten additional variables were recorded and analysed: age, BMI, gender, diabetes, ASA status, procedure length, procedure start time, elective vs. trauma procedure, primary vs. revision procedure and preoperative anticoagulation. Logistic regression modelling was performed to identify factors that independently predict the type of anaesthetic used. General anaesthetic was employed in 280 patients (32%), and regional anaesthesia was the primary anaesthetic type used in 608 (68%). Logistic regression modelling demonstrated that factors that independently predict use of general anaesthetic include younger age (p<0.0001; Odds Ratio 0.97/year), male sex (0.0033; 1.618), procedure start time (0.0319; 1.066/hour) and length of procedure (<0.0001; 1.520/hour). Patients who underwent general anaesthetic had a mean length of procedure of 108 +/− 77 minutes, whereas patients provided with regional anaesthesia had a mean length of procedure 83 +/− 64 minutes. With increasing evidence supporting the benefits of regional anaesthesia in patients undergoing lower extremity surgery, it is important to identify modifiable factors that contribute to patients receiving alternative treatments. Since later procedure start time was identified as an independent predictor of general anaesthetic use, there may be a role for identifying patients at increased risk of complications associated with general anaesthesia and scheduling earlier start times. Furthermore, while it is logical that extended length of procedure may be a contraindication to regional anaesthesia, the mean procedure time of 108 minutes in the general anaesthesia group indicates that many of these patients should still be considered candidates for regional anaesthesia

Foot and ankle surgery is a rapidly evolving specialty. As the number and complexity of cases increases, the number of complaints, litigation and pay-outs has also risen. We aim to assess any learning points discerned from NHS litigation data to allow us help improve patient care. All claims made to the NHS Litigation Authority between 2007 and 2012 relating to foot and ankle problems were obtained under the Freedom of Information Act. These were reviewed, coded and split into subgroups to allow analysis. There were 232 successful litigation cases between 2007 and 2012. The total amount paid out was almost £18.5 million (range £112 to £1.6 million). A significant number of successful cases were due to patients not having full, informed consent. A large amount of money is spent in the NHS is spent on litigation. The amount of litigation and payout in foot and ankle surgery compares favourably with hip and knee surgery. Lack of informed consent is an easily reversible problem that should be decreasing but is actually on the rise. In our trust, we advocate the use of consent clinics which provide a robust and patient-centred approach to informed consent in foot and ankle surgery

In foot and ankle surgery incorrect placement of implants, or inaccuracy in fracture reduction may remain undiscovered with the use of conventional C-arm fluoroscopy. These imperfections are often only recognized on postoperative computer tomography scans. The apparition of three dimensional (3D) mobile Imaging system has allowed to provide an intraoperative control of fracture reduction and implant placement. Three dimensional computer assisted surgery (CAS) has proven to improve accuracy in spine and pelvic surgery. We hypothesized that 3D-based CAS could improve accuracy in foot and ankle surgery. The purpose of our study was to evaluate the feasibility and utility of a multi-dimensional surgical imaging platform with intra-operative three dimensional imaging and/or CAS in a broad array of foot and ankle traumatic and orthopaedic surgery. Cohort study of patients where the 3D mobile imaging system was used for intraoperative 3D imaging or 3D-based CAS in foot and ankle surgery. The imaging system used was the O-arm Surgical Imaging System and the navigation system was the Medtronic's StealthStation. Surgical procedures were performed according to standard protocols. In case of fractures, image acquisition was performed after reduction of the fracture. In cases of 3D-based CAS, image acquisition was performed at the surgical step before implants placement. At the end of the operations, an intraoperative 3D scan was made. We used the O-arm Surgical Imaging system in 11 patients: intraoperative 3D scans were performed in 3 cases of percutaneus fixation of distal tibio-fibular syndesmotic disruptions; in 2 of the cases, revision of reduction and/or implant placement were needed after the intraoperative 3D scan. Three dimensional CAS was used in 10 cases: 2 open reduction and internal fixation (ORIF) of the calcaneum, 1 subtalar fusion, 2 ankle arthrodesis, 1 retrograde drilling of an osteochondral lesion of the talus, 1 Charcot diabetic reconstruction foot and 1 intramedullary screw fixation of a fifth metatarsal fracture. The guidance was used essentially for screw placement, except in the retrograde drilling of an osteochondral lesion where the guidance was used to navigate the drill tool. Intraoperative 3D imaging showed a good accuracy in implant placement with no need to revision of implants. We report a preliminary case series with use of the O-arm Surgical Imaging System in the field of foot and ankle surgery. This system has been used either as intraoperative 3D imaging control or for 3D-based CAS. In our series, the 3D computer assisted navigation has been very useful in the placement of implants and has shown that guidance of implants is feasible in foot and ankle surgery. Intraoperative 3D imaging could confirm the accuracy of the system as no revisions were needed. Using the O-arm as intraoperative 3D imaging was also beneficial because it allowed todemonstrate intraoperative malreduction or malposition of implants (which were repositioned immediately). Intraoperative 3D imaging system showed very promising preliminary results in foot and ankle surgery. There is no doubt that intraoperative use of 3D imaging will become a standard of care. The exact indications need however to be defined with further studies

Background. The focus on evidence-based medicine has led to calls for increased levels of evidence in surgical journals. The purpose of the present study was to review the levels of evidence in articles published in the foot and ankle literature and to assess changes in the level of evidence over a decade. Methods. All articles from the years 2000 and 2010 in Foot and Ankle International, Foot and Ankle Surgery, and all foot and ankle articles from JBJS A and JBJS B were analysed. Animal, cadaveric, basic science, editorials, surveys, letters to Editor and correspondence were excluded. Articles were ranked by a five-point level of evidence scale, according to guidelines from the Centre for Evidence Based Medicine. Results. A total of 379 articles were analysed from a total of 42 different countries. The kappa value for the inter-observer reliability showed very good agreement between the reviewers for types of evidence (κ = 0.785 (P< 0.01)) and excellent agreement for levels of evidence (κ = 0.846 (P< 0.01)). Between 2000 and 2010 the percentage of high level evidence (Levels I and II) increased (5.2% to 10.3%), and low level evidence (levels III, IV and V) decreased (94.8% to 89.7%) (p=0.09). The most frequent type of study was Therapeutic. The JBJS A produced the highest proportion of high-level evidence. The USA and UK were the highest producer of articles. The number of rest-of-world articles (non USA or UK) increased from 40.5% to 46.4% between 2000 and 2010. Conclusion. There has been a trend towards higher levels of evidence in foot and ankle surgery over a decade but the differences did not reach statistical significance

Primary Care Trusts across the country are being encouraged to ration service provision due to austerity measures. Obesity has been suggested as a rationing tool with poor clinical outcomes sited as justification. There is, however, a lack of evidence in the literature pertaining to clinical outcomes post elective foot and ankle surgery in patients with an increased Body Mass Index (BMI). All patients undergoing elective foot and ankle surgery at Queen Alexandra Hospital, Portsmouth are entered into a prospective database, which includes their BMI at time of assessment in clinic. From this, we analysed the notes of all patients with a BMI ≥30, excluding any not operated on between July 2007 and August 2009 or with a BMI of <30 at time of surgery, to determine whether there was an increased incidence of peri- or post-operative complications. Included in the study were 109 patients with a mean age of 54 (range 21 - 79). Female patients accounted for 63% of those notes reviewed and the mean BMI was 34 (range 30 - 50). A mixture of hindfoot and forefoot procedures were carried out (20 different procedures). Median length of stay was 0 nights (range 0 – 15 days). The causes for excessive length of stays (>4 nights) included a pre operative Lower Respiratory Tract Infection missed prior to intubation and the initiation of CPAP post operatively in a patient with known Obstructive Sleep Apnoea. We found 3 cases of post operative Venous Thrombo-embolism within 3 months of surgery and 1 proven wound infection in a non-insulin dependent diabetic patient. Also noted were 3 non-unions, all requiring further surgery. Based on our historical evidence of infective and thrombo-embolic complications in patients with a BMI <30, we conclude that peri- and post-operative complications in obese patients occur no more frequently than in a patient population with a BMI <30

Chronic postoperative pain (CPP) can occur in elective mid/hindfoot and ankle surgery patients. Multimodal pain management has been reported to reduce postoperative pain and opioid use, which may prevent the development of CPP. However, few studies have examined the impact of multimodal pain management strategies on CPP following complex elective mid/hindfoot and ankle surgery. The purpose of this study was to 1) evaluate current pain management strategies and 2) determine current definitions, incidence, and prevalence of CPP after elective mid/hindfoot and ankle surgery. Three databases (MEDLINE, Embase and Cochrane Library) were manually and electronically searched for English language studies published between 1990 and July 2017. For the first aim, we included comparative studies of adults undergoing elective mid/hindfoot and ankle surgery that investigated pre-, peri- or postoperative pain management. For the second aim, we included observational studies examining CPP definition, incidence, and prevalence. Two reviewers independently screened titles and abstracts, followed by full texts. Conflicts were resolved through discussion with a third reviewer. Reviewers also independently assessed the quality of studies meeting inclusion criteria using the Joanna Briggs Institute Critical Appraisal Checklist. For the first aim, 1159 studies were identified by the primary search, and seven high quality randomized controlled trials were included. Ankle arthroplasty or fusion and calcaneal osteotomy were the most common procedures performed. The heterogeneity of study interventions, though all regional anesthesia techniques, precluded meta-analysis. Most investigated continuous popliteal, sciatic and/or femoral nerve blockade. Participants were typically followed up to 48 hours postoperatively to examine postoperative pain levels and morphine consumption in hospital. Interventions effective at reducing postoperative pain and/or morphine consumption included inserting popliteal catheters using ultrasound instead of nerve stimulation guidance, perineural dexamethasone, and adding continuous femoral blockade to continuous popliteal blockade. Using more than one analgesic was generally more effective than using a single agent. Only two studies examined longer term pain management. One found no difference in pain levels and opioid consumption at two weeks with perineural or systemic dexamethasone use. The other found that pain with activity was significantly reduced at six months postoperatively with the addition of a femoral catheter infusion to a popliteal catheter infusion. For the second aim, only two studies of the 747 identified were selected. One prospective observational study defined CPP as moderate-to-severe pain at one year after foot and ankle surgery, and reported 21% and 43% of patients as meeting their definition at rest and with activity, respectively. The other study was a systematic review that reported 23–60% of patients experienced residual pain after total ankle arthroplasty. There is no standardized definition of CPP in this population, and incidence and prevalence are rarely reported and vary largely based on definition. Although regional anesthesia may be effective at reducing in-hospital pain and opioid consumption, evidence is very limited regarding longer-term pain management and associated outcomes following elective mid/hindfoot and ankle surgery

Aim

Treatment recommendations for periprosthetic joint infections (PJI) include surgical debridement, antibiotic therapy or staged revision. In surgical related foot and ankle infections (SR-FAI), implant removal will lead to instability. Debridement is difficult because the implant is outside the joint. Recommendations regarding PJI treatment can therefore not be extrapolated to the treatment of SR-FAI.

Chronic postsurgical pain (CPSP) can occur after elective mid/hindfoot and ankle surgery. Effective treatment approaches for CPSP in this population have not been extensively investigated. The impact of multimodal strategies on CPSP following elective mid/hindfoot surgery is unknown due to both the heterogeneity of acute pain management and the lack of a recognized definition specific to this type of surgery. This study aimed to identify and evaluate current pain management strategies after elective mid/hindfoot and ankle surgery.

We conducted a systematic review under Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Three databases (MEDLINE, Embase and Cochrane Library) were electronically searched for English studies published between 1990 and July 2017. Reference lists of relevant systematic reviews were also manually searched. Comparative studies of adults undergoing elective mid/hindfoot and ankle surgery were included. Two reviewers independently reviewed studies and assessed their methodological quality.

Of 1,159 studies, seven high-quality randomized controlled trials met our inclusion criteria. Though all studies examined regional anesthesia techniques, intervention heterogeneity precluded meta-analysis. Participants were typically followed up to 48 hours post-operatively. Interventions effective at reducing postoperative pain and/or opioid consumption included inserting popliteal catheters under ultrasound instead of nerve stimulation guidance, infusing perineural dexamethasone, bupivacaine, or ropivacaine perioperatively, and adding a femoral catheter infusion to a popliteal catheter infusion. Only one study assessed pain six months following elective mid/hindfoot and ankle surgery, demonstrating significant pain reduction with activity with the addition of a femoral to popliteal catheter infusion.

There is an overwhelming lack of evidence regarding CPSP and its management for patients undergoing elective mid/hindfoot and ankle surgery. Although specific regional anesthesia techniques and adjuncts may be effective at reducing in-hospital pain and opioid consumption after elective mid/hindfoot and ankle surgery, our systematic review identified only seven studies addressing multimodal pain management in this population. Further comparative studies with longer-term follow-up are required.

The saphenous nerve is classically described as innervating skin of the medial foot extending to the first MTP joint and thus is at risk in surgery to the medial ankle and forefoot. However, it has previously been demonstrated by the senior author that the dorsomedial branch of the superficial peroneal nerve consistently supplies the dorsomedial forefoot, leading to debate as to whether the saphenous nerve should routinely be included in ankle blocks for forefoot surgery. We undertook a cadaveric study to assess the presence and variability of the saphenous nerve.

29 feet were dissected from a level 10 cm above the medial malleolus, and distally to the termination of the saphenous nerve. In 24 specimens (83%), a saphenous nerve was present at the ankle joint. In 5 specimens the nerve terminated at the level of the ankle joint, and in 19 specimens the nerve extended to supply the skin distal to the ankle. At the ankle, the mean distance of the nerve from the tibialis anterior tendon and saphenous vein was 14mm and 3mm respectively. The mean distance reached in the foot was 5.1cm. 28% of specimens had a saphenous nerve that reached the first metatarsal and no specimens had a nerve that reached the great toe.

The current study shows that the course of the saphenous nerve is highly variable, and when present usually terminates within 5cm of the ankle. The saphenous nerve is at risk in anteromedial arthroscopy portal placement, and should be included in local anaesthetic ankle blocks in forefoot surgery, as a significant proportion of nerves supply the medial forefoot.

Aims. There is little published on the outcomes after restarting elective orthopaedic procedures following cessation of surgery due to the COVID-19 pandemic. During the pandemic, the reported perioperative mortality in patients who acquired SARS-CoV-2 infection while undergoing elective orthopaedic surgery was 18% to 20%. The aim of this study is to report the surgical outcomes, complications, and risk of developing COVID-19 in 2,316 consecutive patients who underwent elective orthopaedic surgery in the latter part of 2020 and comparing it to the same, pre-pandemic, period in 2019. Methods. A retrospective service evaluation of patients who underwent elective surgical procedures between 16 June 2020 and 12 December 2020 was undertaken. The number and type of cases, demographic details, American society of Anesthesiologists (ASA) grade, BMI, 30-day readmission rates, mortality, and complications at one- and six-week intervals were obtained and compared with patients who underwent surgery during the same six-month period in 2019. Results. A total of 2,316 patients underwent surgery in 2020 compared to 2,552 in the same period in 2019. There were no statistical differences in sex distribution, BMI, or ASA grade. The 30-day readmission rate and six-week validated complication rates were significantly lower for the 2020 patients compared to those in 2019 (p < 0.05). No deaths were reported at 30 days in the 2020 group as opposed to three in the 2019 group (p < 0.05). In 2020 one patient developed COVID-19 symptoms five days following foot and ankle surgery. This was possibly due to a family contact immediately following discharge from hospital, and the patient subsequently made a full recovery. Conclusion. Elective surgery was safely resumed following the cessation of operating during the COVID-19 pandemic in 2020. Strict adherence to protocols resulted in 2,316 elective surgical procedures being performed with lower complications, readmissions, and mortality compared to 2019. Furthermore, only one patient developed COVID-19 with no evidence that this was a direct result of undergoing surgery. Level of evidence: III. Cite this article: Bone Jt Open 2022;3(1):42–53

About 20% of orthopaedic surgery is foot and ankle. This area of orthopaedics has undergone huge changes in last few decades. Not that long ago we were still performing Keller's procedure for bunions and using a Charnley clamp for ankle fusions. It is becoming increasingly more difficult for the general orthopaedic surgeon to stay abreast of current surgical treatment.

Some of the newer foot and ankle surgical surgical techniques will be discussed. Ankle arthroplasty is undergoing a period of revival. This is a difficult procedure with results not as reliable as hip and knee arthroplasty and I would not recommend it to the occasional foot and ankle surgeon. Ankle arthroscopy is now a commonly performed procedure and with the right equipment is a procedure that is useful to the generalist.

Foot and ankle fusion are now performed with rigid internal fixation. The actual procedures are not difficult but it does require a reasonable amount of experience to obtain the correct position of the fusion. Bunion surgery is commonly done and can result in disappointment for all. The newer surgical options for the correction of hallux valgus will be discussed.

Introduction. Hindfoot surgery is assumed to be more painful than midfoot/forefoot procedures with the former often requiring an inpatient stay for pain relief. Poorly controlled pain is associated with adverse patient outcomes and consequently, peripheral nerve blocks (PNB) have become popular for their effective pain control. Aim. To investigate whether hindfoot procedures are more painful than forefoot/midfoot procedures by measuring pain scores, assessing effectiveness of PNBs and patient satisfaction in foot and ankle surgery. Method. In total 140 patients were prospectively studied. Inclusion criteria: Adults undergoing elective foot and ankle surgery. Exclusion criteria: Paediatric patients 16 years and under, those with alternate sources of pain, peripheral neuropathy or incomplete pain scores. Pain was measured via the Visual Analog Scale (VAS) at 3 intervals; immediately, 6 hours and at 24 hours post-operatively. A Johnson patient satisfaction assessment was conducted at 2 weeks. Statistical analysis was performed using SPSS v.18.0. Results. Forefoot/midfoot surgery vs. hindfoot surgery pain scores showed that there was no significant difference at any post-operative interval. PNB vs. no PNB pain scores showed that there was no significant difference at the first two intervals, except at 24 hours post-operatively, p = 0.024. Patients' who had a PNB experienced rebound pain at 24 hours. Overall 94% of patients were satisfied with their experience and anaesthetic. Conclusion. Hindfoot surgery is not more painful than forefoot/midfoot surgery when PNBs are used. Additionally, patients who have a PNB experience rebound pain at 24 hours post-operatively, a finding that requires further research

Periprosthetic joint infections (PJIs) and osteosynthesis-associated infections (OSIs) present significant challenges in trauma and orthopaedic surgery, substantially impacting patient morbidity, mortality, and economic burden. This concern is heightened in patients with pre-existing comorbidities, such as diabetes mellitus, which are not always modifiable at presentation. A novel intraoperative strategy to prevent these infections is the use of Defensive Antibacterial Coating (DAC), a bio-absorbable antibiotic-containing hydrogel applied to implant surfaces at implantation, acting as a physical barrier to prevent infection. The purpose of this study is to assess the use of a commercially available hydrogel (DAC), highlighting its characteristics that make it suitable for managing PJIs and OSIs in orthopaedics and traumatology. Twenty-five patients who underwent complex orthopaedic procedures with intraoperative application of DAC between March 2022 and April 2023 at a single hospital site were included. Post-operative assessment encompassed clinical, laboratory, and radiographic examinations. In this study, 25 patients were included, with a mean age of 70 ± 14.77 years and an average ASA grade of 2.46 ± 0.78. The cohort presented an average Charleston Comorbidity score of 5.45 ± 2.24. The procedures included 8 periprosthetic fractures, 8 foot and ankle surgeries, 5 upper limb surgeries, and 4 elective hip and knee surgeries. Follow-up assessments at 6 weeks and 6 months revealed no evidence of PJI or OSI in any patients, nor were any treatments for PJI or OSI required during the interim period. DAC demonstrated efficacy in preventing infections in high-risk patients undergoing complex orthopaedic procedures. Our findings warrant further investigation into the use of DAC in complex hosts with randomized control trials

Reported wound complication in below knee surgery can be quite high. Recent study demonstrated that increased blood loss and hematoma formation increase wound complications especially in foot and ankle surgeries. Despite the evidence on the benefit of TXA on blood loss in TKA and THA it is not routinely used by surgeon in below knee surgery. To assess the efficacy and safety of this medication in reducing wound complication and blood loss and the risk of thromboembolic complications in patients undergoing below knee surgery. A systematic literature search of PubMed, Embase, Ovid, the Cochrane Library and AAOS and AOFAS conference proceedings was conducted. The primary outcome was the rate of wound complications. Data were analyzed using the Review Manager 5.3 software. Nine studies involving 861 patients met the inclusion criteria. The meta-analysis indicated that TXA, when compared to a control group, reduced wound complications (OR, 0.54; 95% IC, 0.31 to 0.95, p = 0,03), blood loss (MD = −149,4 ml; 95% CI, −205,3ml to −93,6ml), post-operative drainage (MD = −169,8 ml; 95% CI, −176,7 to −162,9 ml) and hemoglobin drop (MD = −8,75 g/dL; 95% IC, −9,6 g/dL to −7,8 g/dL). There was no significant difference in thromboembolic events (RR 0,53; 95% CI, 0,15 - 1,90; p = 0,33). This study demonstrated that TXA could be use in below knee surgery to reduce wound complication and blood loss without increased thromboembolic complications. The small number of studies limit the findings interpretation. Further studies are needed to sustain those resutls

Introduction. This study aimed to assess the relationship between preparation times and operative procedures for elective orthopaedic surgery. A clearer understanding of these relationships may facilitate list organisation and thereby contribute to improved operating theatre efficiency. Methods. Two years of elective orthopaedic theatre data was retrospectively analysed. The hospital medical information unit provided de- identified data for 2015 and 2016 elective orthopaedic cases, from which were selected seven categories of procedures with sufficient numbers to allow further analysis - primary hip and knee replacement, spinal surgery, shoulder surgery (excluding shoulder replacement), knee surgery, foot and ankle surgery (excluding ankle replacement), Dupuytrens surgery and general orthopaedic surgery. The data analysed included patient age, ASA grade, operation, operation time, and preparation time (calculated as the time from the start of the anaesthetic proceedings to the patient's admission to Recovery, with the operating time [skin incision to skin closure] subtracted). Statistical analysis of the data was undertaken. Results. A total of 1596 procedures performed over the two year period were analysed. Preparation times for the different procedures were assessed, along with the relationship to the procedure complexity. Neither age nor ASA correlated strongly with preparation times. Spine procedures had greater preparation times than hip and knee arthroplasty. Greater uniformity in preparation times for hip and knee arthroplasty was seen across the anaesthetic group than operative times across the surgeon group. Discussion. Preparation times are just one aspect that may be evaluated with regard to theatre utilisation. This study did not address the theatre turn-over time between cases, which includes transfer of the patient from the admitting/pre-operative area into the theatre. Conclusion. Preparation times for elective procedures follow a pattern which may be used to inform list planning, with the potential for greater theatre efficiencies with regard to list utilisation and staff allocation

Introduction. Continuous compression implants (CCIs) are small memory alloy bone staples that can provide continuous compression across a fracture site, which change shape due to temperature changes. Reviews of CCIs in orthopaedics have documented their use in mainly foot and ankle surgery, with very limited descriptions in trauma. They could be beneficial in the management of complex or open injuries due to their low profile and quick insertion time. The aim of this case series were to clarify the use of CCIs in modern day limb reconstruction practice. Materials & Methods. This was a single centred study looking retrospectively at prospective data for patients who were treated for an acute fracture or non-union with a CCI between September 2019 and May 2023. Primary outcome was to determine the function and indication of the CCI as judged retrospectively and secondary outcomes investigated unplanned returns to theatre for infection or CCI failure. Results. Sixty patients were eligible with a mean age of 44.2 (range 8–89). Fifty-one patients were treated for acute fractures, nine for non-unions; and almost half (27 patients) had open injuries. There were seven different sites for treatment with a CCI, the most common being tibia (25 patients) and humerus (14 patients). Of the 122 CCIs used, 80 were used as adjuncts for fixation in 48 patients. Their indication as an adjunct fell into three distrinct categories – reduction of fracture (39 CCIs), fixation of key fragments (38 CCIs) and compression (3 CCIs). Of these 48 patients, 4 patients had a frame fixation, 19 had a nail fixation, 24 patients had a plate fixation. Forty-two CCIs were used in isolation as definitive fixation, all were for midfoot dislocations expect an open iliac wing fixation from a machete attack and an isolated paediatric medial malleolus fixation. Two patients returned to theatre for infection and two due to CCI failure. Conclusions. This series has demonstrated the versality of CCIs across multiple sites of the body and for a large variety of injuries. It has identified, when not used in isolation, three main indications to support traditional orthopaedic fixations. Given the unpredictability in limb reconstruction surgery, the diversity and potential of CCIs could form part of the staple diet in the modern-day practice

In the current health care climate, there is an increasing focus on cost savings and resource management. As such, there is an emphasis on decreasing length of stay and performing surgery on an outpatient basis. Consequently, some patients will have unanticipated intra-operative or post-operative adverse events that will necessitate an unplanned post-operative hospital admission or a readmission after discharge. These unplanned admissions or readmissions represent an increased burden on health care systems and can cause cancellation of other scheduled procedures. The purpose of this study is to investigate whether pre-operative patient risk factors or intra-operative events could predict unplanned admission or readmission following discharge in patients undergoing either elective or emergency foot and ankle surgery. Data was prospectively collected on a total of 889 patients. The patients were divided into two groups: patients without readmissions (N=791) and patients who had an unplanned admission or readmission (N=98). We also collected and analysed the following variables: age, gender, BMI, diabetes, ASA class, surgery start time, length of surgery, regional vs. general anesthetic, elective vs. trauma surgery and type of procedure. Logistic regression models were used to identify risk factors that could independently predict unplanned admissions or readmissions to hospital following foot and ankle surgery. Factors that could be used to independently predict readmission were length of surgery (p 0.0154, Odds Ratio 1.004) and trauma surgery (0.0167; 1.978). For every 1-hour increase in length of surgery, the odds of unplanned admission/readmission increase by 1.27 times. The odds of patients undergoing surgery for acute traumatic injuries getting readmitted are 1.978 times higher than for elective surgery patients. In conclusion, our study showed that pre-operative patient risk factors including BMI, diabetes, and ASA status were unable to predict whether patients would have an unplanned admission or readmission. The two factors that were able to predict whether patients would have an unplanned admission or readmission were length of the procedure and trauma surgery – both of which are not readily modifiable. Our results showed that in spite of institutional measures to ensure timely discharge, only 11% of patients required an unplanned admission or readmission

Spezializing in subfields of Orthopaedics is common in anglo-american countries for more than 20 years. IThe aim of this paper is to demonstrate the necessity of fellowship programms in extremity orientated subfileds of orthopaedics. Analyzing the results of ankle arthrodesis performed by general orthopaedic surgeons campared to ankle arthrodesis performed by spezialized foot and ankle surgeons the difference in results will be demonstrated. Patients and methods. In 40 patients an ankle arthrodesis was performed between 1998 and 2012. Group A was formed by 20 consecutive patients treated by spezial trained Foot and Ankle surgeons and group B was formed by 20 patients treted by general orthopaedic surgeons. The average age in group A at the time of surgery was 59,9y (34 to79y) compared to 63,4y (41 to 80y) in group B. The average follow up was 34 months respectively 32 months after surgery. The study included a spezial questionnaire with the AOFAS score and rating of patients dissatisfaction. The successful healing of the arthrodesis was determied by using standardized radiographs, Furthermore a pedobarography, and a videoanalyzis of the walking was incuded. Results. All procedures in group A were performed using an anterior approach. Neither pseudarthroses, equinus or other malositions were detected in this group. In group B wurdenin 16 patients an anterior and in 4 patients a lateral approach was used. Complications included 3 pseudarthroses, 4 equinus malpositions, 4 varus malpositions, 4 valgus malpositions and 8 penetrations of the subtalar joint. The AOFAS score on average was 78 (46–92) points in group A and 75 (34 – 94) in group B. Conclusion. The analyzis of the data revealed that the results in Group A were comparable to the results published in the literature. Results in group B were inferior to those in group A and to the results published in the literature of Foot and Ankle surgery. Foot and Ankle surgery became more demanding over the last decades. As already shown in anglo-american countries spezializing in certain fields of orthopaedics is a necessity. More complex hindfoot surgery should be performed in special centers with an adequate case load

Anesthetic peripheral nerve blocks (PNB) have been shown to be more advantageous than general anesthesia in a variety of surgical operations. In comparison to conventional methods of general anesthesia, the choice of regional localized infiltration has been shown to shorten hospital stays, decrease hospital readmissions, allow early mobilization, and reduce narcotic use. Perioperative complications of PNBs have been reported at varying rates in literature. Thus, the purpose of this study was to provide a review on the clinical evidence of PNB complications associated with foot and ankle surgeries. A systematic review of the literature was completed using PubMed search terms: “lower extremity”, “foot and ankle”, “nerve block”, and “complications”. All studies reporting minor and major complications were considered along with their acute management, treatments, and postoperative follow up timelines. The range of complications was reported for Sensory Abnormalities, Motor Deficits, Skin and systemic complications (local anesthetic systemic toxicity & intravascular injections). A designation of the scientific quality (Level I-IV) of all papers was assigned then a summary evidence grade was determined. The search strategy extracted 378 studies of which 38 studies were included after criteria review. Block complications were reported in 20 studies while 18 studies had no complications to report. The quality of evidence reviewed ranged from Level I to Level IV studies with follow up ranging from twenty four hours to one-three year timelines. The range of complications for all studies reporting sensory abnormalities was 0.53 to 45.00%, motor deficits 0.05 to 16.22% and skin and systemic complications 0.05 to 6.67%. Sensory abnormalities that persisted at last follow up occurred in six studies with incidence ranging from 0.23 to 1.57%. Two studies reported motor complications of a foot drop with an incidence of 0.05% and 0.12%. When considering only the highest quality studies (Level 1) that had complications to report, the complications rate was 10.00% to 45.00% for sensory abnormalities, 7.81 to 16.22% for motor deficits, 6.67% for skin complications and 2.50% for systemic complications. High quality studies (Level I providing Summary Grade A Evidence) reporting all complications with a range of incidence from 0 to 45%. While most of these complications were not serious and permanent, some were significant including sensory abnormalities, foot drop and CRPS. Based on this systematic review of the current literature, the authors emphasize a significant rate of complications with PNB and recommend that patients are appropriately informed prior to consenting to these procedures

Ankle arthrodesis and replacement are the widely accepted options in managing end-stage ankle arthritis. Ankle replacement as an alternate treatment option for ankle arthritis is relatively new and this is in large part to the successes observed with hip and knee arthroplasty for arthritis. Relative benefits of ankle replacement and arthrodesis remains a contentious topic. We conducted a multicenter pilot randomized controlled trial, first of its kind, comparing the clinical outcomes of ankle arthrodesis and ankle replacement in managing ankle arthritis. We hypothesized that clinical outcomes would be similar for both. Patients recruited for this study were part of Canadian Orthopaedic Foot and Ankle Society (COFAS) Database. Canadian orthopaedic surgeons with fellowship training in foot and ankle surgery or extensive experience in the surgical treatment of end stage ankle arthritis determined whether the patient met the criteria for randomization, skeletal maturity, symptomatic ankle arthritis no longer amenable to non-operative management, and ability to give informed consent. Data was collected on patient demographics, follow-up time period, complication rates, and Ankle Osteoarthritis Scale (AOS) and Short Form-36 (SF-36) scores. Our analysis of clinical outcomes was divided into two parts: (1) comparison of pre and postoperative data for each cohort separately, and (2) comparison of outcome scores, and revision rates between both cohorts. We employed the Student's t-test and calculated effect sizes in assessing improvements in AOS and SF-36 scores from baseline to latest follow-up within and between the two groups. We also examined postoperative complication and reoperation rates in the study population using the standardized coding system for reoperations following ankle replacement and arthrodesis. Thirty-nine ankles were enrolled in the study with a mean follow-up of 5.1 ± 2.8 years. Ankle osteoarthritis scale scores improved significantly from baseline and last follow-up in both groups. The average baseline AOS total score for ankle replacement improved from 59.4 ±15.9 to 38 ±20 at last follow-up (p-value 19.7 to 31.8 ±16.5 at last follow-up (p-value 25.4 compared to ankle replacement's 20.3 ±23. Two major complications (10.5%) were observed in the ankle replacement cohort while the ankle arthrodesis cohort saw four major complications (20%). Clinical outcomes of ankle replacement and arthrodesis were comparable. The ankle arthrodesis cohort held a slight advantage over ankle replacement in improvement of AOS scores, though not statistically significant. Rates of major complications and reoperations were higher with ankle arthrodesis
