Total ankle replacement (TAR) is performed for post-traumatic arthritis, inflammatory arthropathy, osteoarthritis and other indications. The Scottish Arthroplasty Project (SAP) began collection of data on TAR in 1997. In this study, using data from the SAP, we look at trends in the use and outcomes of TAR in Scotland. We identified 499 patients from the SAP who underwent TAR between 1997 and 2015 with imaging available on the National Picture Archiving and Communication System (PACS). We identified, and looked at trends in, implant type over the following time periods: 1998–2005; 2006–2010 and 2011–2015. Age, gender, indication and outcomes for each time period were examined and also trends with implant type over time.Introduction
Methods
Surgical options for management of a failed ankle arthroplasty are currently limited; typically conversion to fusion is recommended with only a few patients being considered for revision replacement surgery. This paper presents our experience of revision ankle replacements in a cohort of patients with failed primary replacements. A total of 18 revision TAR in 17 patients were performed in patients with aseptic loosening. The technique was performed by a single surgeon (CSK) over a 4 year period between July 2014 and August 2018 using the Inbone total ankle replacement system. Patient demographics and clinical outcomes were collected retrospectively using - MOXFQ, EQ5D, VAS pain score and patient satisfaction questionnaires.Aim

Isolated Weber B fractures usually heal uneventfully but traditionally require regular review due to the possibility of medial ligament injury allowing displacement. Following recent studies suggesting delayed talar shift is uncommon we introduced a functional treatment protocol and present the early results. 141 consecutive patients presenting acutely with Weber B fractures without talar shift between January and December 2015 were included. Patients were splinted in a removable boot and allowed to weight bear. ED notes and radiographs were reviewed by an Orthopaedic consultant. Patients without signs of medial injury were discharged with an information leaflet and advice. If signs of medial ligament injury were noted or the medial findings were not documented the patient was reviewed in fracture clinic at 4 weeks post-injury. If talar shift developed the patient was to be converted to operative treatment. Olerud and Molander scores were collected between 6 and 12 months post-injury..Introduction

Total ankle replacement (TAR) is performed for post-traumatic arthritis, inflammatory arthropathy, osteoarthritis and a range of other indications. The Scottish Arthroplasty Project (SAP) began collection of data on TAR in 1997. In this study, using data from the SAP, we examined the annual incidence of TAR between 1997 and 2015. Implant survivorship and the rate of general and joint-specific complications were also analysed. We identified 601 patients from a national arthroplasty database who had undergone total ankle replacement between 1997 and 2015 and followed up these patients to a maximum of 20 years. We used established methods of linkage with national hospital episode statistics, population and mortality data to examine the incidence of complications and implant survivorship.Introduction
Methods
Isolated Weber B fractures usually heal uneventfully but traditionally require regular review due to the possibility of medial ligament injury allowing displacement. Following recent studies suggesting that delayed talar shift is uncommon we introduced a functional treatment protocol and present the early results. 86 patients presenting acutely with Weber B fractures without talar shift between January and July 2015 were included. Patients were splinted in a removable boot and allowed to weight bear. ED notes and radiographs were reviewed by an Orthopaedic consultant. Patients without signs of medial injury were discharged with an information leaflet and advice. If signs of medial ligament injury were noted or the medial findings were not documented the patient was reviewed in fracture clinic at 4 weeks post-injury. If talar shift developed the patient was to be converted to operative treatment. MOXFQ and EDQ5 scores were collected. 50 patients had signs of medial ligament injury or no documented medial findings and of these 43 attended fracture clinic. Of 36 patients without signs of medial ligament injury 28 were discharged according to protocol and 8 patients attended fracture clinic. One discharged patient re-accessed care. Of 52 patients reviewed in the fracture clinic none developed delayed talar shift and all continued with non-operative treatment. The outcome scores were comparable to those in the published literature. We conclude the risk of delayed talar shift is low and satisfactory outcomes can be safely achieved with our functional protocol. Additional tests/imaging to establish the integrity of the medial ligament may be unnecessary.
Calcaneal fracture fixation over the past decade has been practised via an extensile lateral incision. This can be complicated by infection and wound breakdown. We have developed a new technique for fixation of the calcaneal fractures – MACO. We utilise a 4 cm sub fibular incision to aid joint visualisation and fracture reduction. Fixation is via percutaneous screws. We analysed our prospectively collected database. 26 fractures were fixed over an 18 month period at Glasgow Royal Infirmary by three consultant surgeons. 22 patients were male and half were smokers. Mean follow up was 5 months (range 1.5 – 18 months). The mean age of our patients is 41 (range 25–68). The mean pre operative Bohler's angle was 16.7 degrees. Gissane's angle was similarly abnormal with a mean of 129 degrees. The average duration of surgery was 73 minutes (range 45–100 minutes). Post operatively, Bohler's angle was improved. The mean was 29 degrees. There was no significant difference with Gissane's angle. The mean was 128 degrees. There were no superficial wound infections. One patient was troubled by wound breakdown with subsequent deep infection. There was no need for metalwork removal in our series of patients. Two patients developed post traumatic osteoarthritis of the sub talar joint. Only one has required sub talar joint fusion. We conclude that the novel technique which we describe is successful in restoring calcaneal anatomy with few complications. Further follow up is needed to determine the long term outcomes of such surgery.
In this cohort study, we present comprehensive injury specific and surgical outcome data from one of the largest reported series of distal tibial pilon fractures, treated in our tertiary referral centre. A series of 76 pilon fractures were retrospectively reviewed from case notes, plain radiographs and computed tomography (CT) imaging. Patient demographics, injury and fracture patterns, methods and timing of fixation and clinical and radiological outcomes were assessed over a mean follow up period of 8.6 months (range 2–30).Introduction:

Peroneal muscle weakness is a common pathology in foot and ankle surgery. Polio, charcot marie tooth disease and spina bifida are associated with varying degrees of peroneal muscle paralysis. Tibialis Posterior, an antagonist of the peroneal muscles, becomes pathologically dominant, causing foot adduction and contributes to cavus foot posture. Refunctioning the peroneus muscles would enhance stability in toe off and resist the deforming force of tibialis posterior. This study determines the feasibility of a novel tendon transfer between peroneus longus and gastrocnemius, thus enabling gastrocnemius to power a paralysed peroneus tendon. 12 human disarticulated lower limbs were dissected to determine the safety and practicality of a tendon transfer between peroneus longus and gastrocnemius at the junction of the middle and distal thirds of the fibula. The following measurements were made and anatomical relationships quantified at the proposed site of the tendon transfer: The distance of the sural nerve to the palpable posterior border of the fibula; the angular relationship of the peroneus longus tendon to gastrocnemius and the achilles tendon; the surgical field for the proposed tendon transfer was explored to determine the presence of hazards which would prevent the tendon transfer.Introduction:
Method:
A series of 76 distal tibial pilon fractures treated with surgical fixation were retrospectively reviewed from case notes, plain radiographs and CT imaging. Patient demographics, injury and fracture patterns, methods and timing of fixation and clinical and radiological outcomes were assessed over a mean follow up period of 8.6 months (range 2–30). Definitive fixation was most commonly performed through an open technique (71 cases) with plate fixation. CT imaging was used to plan the most direct approach to access the fracture fragments. Single or double incision techniques were used to access the tibia, with fixation of the fibular performed when necessary. Superficial infection occurred in 5 cases (6.9%) and deep infection in 2 (2.8%). Aseptic wound breakdown occurred in 5 cases (6.9%). The rate of wound breakdown after three-incision technique was 37.5%. There were 10 cases of non-union (13.9%) and 8 of mal-union (10.5%). Post-traumatic arthritis was present on the most recent x ray in 17 cases (23.4%). Further surgery was required in 20 cases (27.8%), most commonly for metalwork related problems and also for treatment of non-union, post-traumatic arthritis and infection. This review gives comprehensive injury specific and surgical outcome data from one of the largest reported series of these complex and problematic injuries.
Fifth metatarsal fractures are common and the majority unite regardless of treatment. A sub-type of these fractures carries a risk of non-union and for this reason many centres follow up all 5th metatarsal fractures. In 2011, a standardised protocol was introduced to promote weight-bearing as pain allowed with a tubigrip or Velcro boot according to symptoms. No routine fracture clinic appointments were made from A&E but patients were provided with information and a help-line number to access care if required. Some patients still attended fracture clinics, but only after review of their notes/X-rays by an Orthopaedic Consultant, or after self-reported “failure to progress” using the special help-line number. Audit of a year prior to the introduction of the protocol and the year following it was performed. All x-rays taken at presentation in A&E were reviewed and classified independently (KBF/JM) for validation. During 2009/2010, 279 patients presented to A&E with a 5th metatarsal fracture and were referred to a fracture clinic. 106(38%) attended 1 appointment, 130(47%) attended 2 appointments and 31 (11%) attended 3 or more appointments – 491 appointments in total. 3% failed to attend the clinic. Operative fixation was performed in 3 patients (1.07%). In 2011/2012, of 339 A&E fractures, only 63 (19%) attended fracture clinic. 37 (11%) attended 1 appointment, 12 (4%) 2 and 9 (3%) 3 or more appointments – 96 appointments in total. Four patients (1.17%) required operative fixation. Our study did not demonstrate any added value for routine outpatient follow-up of 5th metatarsal fractures. Patients can be safely allowed to weight bear and discharged at the time of initial presentation in the A&E department if they are provided with appropriate information and access to a “help line” run by experienced fracture clinic staff. The result is a more efficient, patient-centred service.
We aimed to review the outcome of Agility total ankle replacements carried out in our institution between 2002 and 2006. Follow-up consisted of clinical and radiological review pre-operatively, then at 6 weeks, 6 and 12 months, and annually until 10 years post op. Clinical review included the American Orthopaedic Foot and Ankle Score, satisfaction and pain scores. Case notes were reviewed to determine intra and post-operative complications. 30 arthroplasties were performed in 30 consecutive patients. Pre-operative diagnosis was rheumatoid arthritis(16), primary osteoarthritis(12) and post-traumatic osteoarthritis(2). After a mean follow up of 6.2 years (1.4–10.1), 4 patients had died, and 22 out of the remaining 24 were available for follow-up. Intra operative complications included lateral malleoli fracture(3) and superficial peroneal nerve injury(2). Post operative complications included 1 early death, but this was not related to the surgical procedure. Two patients developed deep infections of the prosthesis. One underwent removal of the implant; the other is on long term oral antibiotic therapy. One patient had delayed union of the syndesmosis and six patients had non-union. On clinical assessment, patients' AOFAS scores improved from mean 40.4 pre-op to 83.5 post-op (p<0.001). Radiological assessment of the tibial component revealed 25 (93%) patients had lucency in at least one zone in the AP radiograph. We found a relatively high level of re-surgery and complications following Agility total ankle replacement. A 7% revision rate is much higher than would be tolerated in knee or hip arthroplasty, but compares favourably to other studies of TAR. Despite radiological features which suggest loosening, the high rate of re-surgery and complications; patients are generally satisfied with the procedure, reporting lower levels of pain and improved function. Overall we feel that the Agility ankle is an acceptable alternative to ankle arthrodesis, however patients need to be warned of the risk of re-surgery.
Tibiotalocalcaneal (TTC) arthrodesis using a retrograde nail is a common salvage procedure for a range of indications. Previous work has suggested subtalar joint preparation is unnecessary to achieve satisfactory results. We examine the incidence of symptomatic subtalar nonunion following tibiotalocalcaneal fusion in a series of patients, all of whom had full preparation of the subtalar joint, and consider the possible contributing factors. We performed a retrospective review of all patients who underwent TTC arthrodesis from 2004–2010. All fusions were performed by the same surgeon with full preparation of both tibiotalar and subtalar joints. 61 TTC arthrodeses were performed in 55 patients (mean age = 59 years) using an intramedullary retrograde nail. Mean follow-up was 18 months (6–48 months). Fifty-six ankles (92%) achieved satisfactory union. Five patients (8%) had symptomatic non-union: 4 patients of the subtalar joint - with 3 patients undergoing revision subtalar arthrodesis and 1 patient of the tibiotalar joint. Nine patients required removal of the calcaneal screw (16%) – all had evidence of isolated subtalar nonunion prior to metalwork failure. Eight of these patients achieved asymptomatic union following screw removal. Subtalar nonunion following TTC fusion has resulted in recent changes to nail design to increase stability across the subtalar joint. Our results demonstrate a favourable overall nonunion rate with isolated subtalar nonunion making up the majority of cases. We also observed a significant rate of distal screw loosening, also associated with subtalar nonunion prior to screw removal, the significance of which merits further investigation.
Fifth metatarsal fracture is a common injury. Current practice supports conservative management, with surgery in the event of non-union. Early fracture clinic review is not perceived to improve patient experience or increased detection of non-union. A new protocol standardises treatment to symptom level and discharges patients from ED with advice but without any routine follow-up arranged. A leaflet advises on management, prognosis and helpline details and there is an open-access policy for those whose symptoms persist to investigate potential non-union. A prospective audit evaluated the protocol, surveying patients at 8-weeks and 6-months post-injury. A minor injuries unit continued to refer to fracture clinic and was the control group. During 6-months 46 acute fractures were recorded in the new protocol(group 1) and 47 in the control(group 2). 1 patient in each group was known to experience non-union. 31 of group 1 and 22 of group 2 responded to at least one survey.Introduction

Isolated talonavicular arthrodesis is a common procedure particularly for posttraumatic arthritis and rheumatoid arthritis. Two surgical approaches are commonly used: the medial and the dorsal approach. It is recognized that access to the lateral aspect of the talonavicular joint can be limited when using the medial approach and it is our experience that using the dorsal approach addresses this issue. We performed an anatomical study using cadaver specimens, to compare the amount of articular surface that can be accessed, and therefore prepared for arthodesis, by each surgical approach. Medial and dorsal approaches to the talonavicular joint were performed on each of 11 cadaveric specimens (10 fresh frozen, 1 embalmed). Distraction of the joint was performed as used intraoperatively for preparation of articular surfaces during talonavicular arthrodesis. The accessible area of articular surface was marked for each of the two approaches using a previous reported technique3. Disarticulation was performed and the marked surface area was quantified using an immersion digital microscribe, allowing a three dimensional virtual model of the articular surfaces to be assessed. The median percentage of accessible total talonavicular articular surface for the medial and dorsal approaches was 71% and 92% respectively. This difference was significant (Wilcoxon Signed Ranks Test, p<0.001). This study provides quantifiable measurements of the articular surface accessible by the medial and dorsal approaches to the talonavicular joint. These data support for the use of the dorsal approach for talonavicular arthrodesis.

A delay in operative intervention for ankle fracture in the presence of blistering at the operative site is generally considered to reduce problems with soft tissue complications including infection. No evidence exists to show an increased rate of complications. Previous work has characterised two types of blisters clear- and blood-filled. It has been suggested that the presence of a blood-filled blister confers a higher risk of wound healing complications compared with a clear-filled blister. We present a series of patients who underwent surgery for ankle fracture, in the presence of blisters at the operative site, without any change to standard management of the fracture. We also present a review of the literature. We prospectively followed six patients who underwent early internal fixation (no delay in surgical intervention) of ankle fracture in the presence of blisters at the operative site. In many cases the surgical incisions were made through the blistered skin. No patients had any additional treatment for their blisters. All patients were treated with the same postoperative protocol. All six patients with both blister types went on to fracture union with no soft tissue complications and no cases of infection. This initial observational study supports the treatment of ankle fractures with early internal fixation in the presence of soft tissue blisters at the operative site. It is possible that the stabilisation of underlying skeleton results in better healing of the skin and other soft tissues which is a concept often employed in the management of open fractures. We plan to carry out further prospective work on a larger number of patients as part of a randomized trial to confirm this finding.
We undertook a retrospective audit to assess quality of service provided by Nurse-Led Review Clinic at Glasgow Royal Infirmary for patients sustaining ankle fracture requiring surgical stabilisation. Nursing staff had received training from the senior author regarding clinical examination and radiograph interpretation. We retrospectively reviewed the clinical documentation and radiographs of 104 patients who attended from January 2009 to December 2009. Any clinical issues were identified and radiographs were scrutinised by two of the authors to assess accuracy of interpretation. Nurse-led management was then assessed as to its appropriateness. Finally two retrospective questionnaires were used to assess both the nurses and patients satisfaction with the clinic. Nurse-led clinic protocol: First appointment 10 days: Wound review, application of lightweight plaster. Second appointment 6 weeks: Removal of plaster, check radiographs. Final appointment 12 weeks: Clinical assessment, radiographs, discharge. Clinical assessment: ensure wound satisfactory, range of movement and weight-bearing are improving. Radiographic criteria: 6 weeks: Assess for talar shift, lucency or metal-work concerns. 12 weeks: Assess evidence of fracture union, infection, loosening or backing out. If any concerns with the patients' progress nursing staff would discuss with the consultant. First appointment: 7 wound problems. 5 managed by nurses and resolved. 2 discussed with surgeon, 1 settled, 1 required oral antibiotics. 3 radiographs discussed with surgeon. 2 conservative management. 1 re-operation. Second appointment: 7 wounds managed by nurses. 1 failure of fixation, discussed for re-operation. 2 concerns regarding metal in joint – treated conservatively. Final appointment: 7 referred to physiotherapy as slow to fully weight-bear. 5 discussed for removal of syndesmosis screw. 1 screw in joint, admitted for re-operation. Clinical care provided at Nurse-Led clinic is appropriate and effective. Both nursing staff and patients were satisfied with the care provided. Nurse-led clinic reduces demands on fracture clinic appointments and is a safe, cost effective initiative.
The exact action of the Peroneus Longus muscle on the foot is not fully understood. It is involved in a number of pathological processes like tendonitis, tenosynovitis, chronic rupture and neurological conditions. It is described as having a consistent insertion to the base of the first metatarsal, but there have also been reports of significant variations and additional slips. Our aim was to further clarify the anatomy of the main insertion of the Peroneus Longus tendon and to describe the site and frequency of other variable insertion slips. The course of the distal peroneus longus tendon and its variable insertion was dissected in 20 embalmed, cadaveric specimens. The surface area of the main insertion footprint was measured using an Immersion Digital Microscibe and 3D mapping software. The site and frequency of the other variable insertion slips is presented. There was a consistent, main insertion to the infero-lateral aspect of the first metatarsal in all specimens. The surface area of this insertion was found to be proportional to the length of the foot. The insertion in males was found to be significantly larger than females. The most frequent additional slip was to the medial cuneiform. Other less frequent insertion slips were present to the lesser metatarsals. The main footprint of the Peroneus Longus tendon is on the first metatarsal. There appears to an additional slip to the medial cuneiform frequently. Although we are unsure about the significance of these additional slips, we hope it will lead to a better understanding of the mechanism of action of this muscle and its role both in the normal and pathological foot.
The arterial supply of the talus has been extensively studied in the past but there is a paucity of information on the arterial supply to the navicular and a very limited understanding of the intra-osseous supply to the surface of either of these bones. This is despite the likely importance of this supply in relation to conditions such as osteochondral lesions of the dome of the talus, and avascular necrosis and stress fracture of the navicular. Using cadaveric limbs, dissection of the source vessels was performed followed by arterial injection of latex. The talus and navicular were then removed en bloc, preserving the integrity of the injected arterial vasculature. The specimens were then processed using a new, accelerated diaphanisation technique. This rendered the tissue transparent, allowing the injected vessels to be visualised and then mapped onto a 3D virtual reconstruction of the bone. The vasculature to the subchondral surfaces of the talus and navicular, and the source vessel entry points that provide arterial supply into the navicular were identified. This study gives quantifiable evidence of the areas of consistently poor blood supply which may help explain the clinical pattern of talar and navicular pathology. It also provides as yet unpublished information on the arterial supply of the human navicular bone.
Regional anaesthetic for foot surgery has been discussed as a method of post operative analgesia. Ankle block as the sole anaesthetic for foot surgery has not been extensively reviewed in the literature. We aimed to describe our experience of forefoot surgery under ankle block. Sixty-six consecutive forefoot procedures (59 patients) were carried out under ankle block. Patients were contacted post operatively and completed a standardised questionnaire including an incremental pain assessment ranging from 0-10 (0 no pain, 10 severe pain). Forty nine female and 10 male patients (age range 20-85y) were included. Procedures included 33 first metatarsal osteotomies, 15 cheilectomies, 3 first MTP joint replacements, 5 fusions, 4 excision of neuroma and 6 other procedures. 22 patients (33% of cases) reported discomfort during the block procedure (average pain score 1.5). 6 patients reported pain during their operation(s), average score 0.26. Average pain scores at 6, 12, 24 and 48 hours following surgery were 2.0, 3.2, 2.7 and 2.1 respectively. All patients were discharged home and walking on the same day. There were no readmissions. Each patient confirmed they would have surgery under regional block rather than general anaesthesia and would recommend this technique to family and friends. There are many advantages in being able to perform these relatively small procedures under regional anaesthesia. The anaesthesia obtained permits the majority of forefoot procedures and provides lasting post-operative analgesia. Combined with intra-operative sedation, use of ankle tourniquet and same day discharge; it has very high patient acceptance and satisfaction.

To describe our experience of forefoot surgery under ankle block. 71 consecutive forefoot procedures (65 patients) were carried out under ankle block. A mixture of 10ml 2% Lidocaine with 10ml 0.5 % Bupivacine was administered to the superficial peroneal, deep peroneal, sural and saphenous nerves. Ankle tourniquet was employed in all procedures.

Methods
Advantages of arthroscopic surgery in orthopaedic practice are well documented. The use and scope of ankle arthroscopy has evolved in the last decade. Its role in both the evaluation and treatment of chronic ankle pain has become more important with identification of newer pathologies. We aimed to identify the indications and complications of ankle arthroscopy in chronic ankle pain and to correlate the arthroscopic findings with pre-operative MRI/CT. A retrospective analysis of all procedures done in our unit from 2005-2009. Patient records, X- rays and scans were reviewed. 77 patients were included in the study (46 male/31 female). The commonest age group was the 4th decade. There was a male preponderance in the younger age group (<50y), and a female preponderance in the older age groups (>50y). The commonest indication was impingement syndrome (44%/mean age 38y), followed by osteochondral lesions of the talus (23%/mean age 36y) and Osteoarthritis (22%/mean age56y). Other pathology included synovitis, Rheumatoid Arthritis, instability, AVN and combined pathologies. Pre-op MRI scans correlated with arthroscopic findings in 59%. The pathology most missed by MRI was impingement. 1 patient developed wound infection and another iatrogenic tendon rupture. 78% reported improvement in their symptoms following the procedure. Ankle arthroscopy is a safe and effective procedure. It is particularly useful in the diagnosis and treatment of impingement syndromes and osteochondral lesions. Although there are serious recognised complications, their incidence is low. Patients with chronic symptoms and normal MRI/CT may have treatable pathology on arthroscopy.
Regional anaesthetic for foot surgery has been discussed as a method of post operative analgesia. Ankle block as the sole anaesthetic for foot surgery has not been extensively reviewed in the literature. We aimed to describe our experience of forefoot surgery under ankle block alone. 21 consecutive forefoot procedures (18 patients) were carried out under ankle block. The blocks were performed by the senior authors. A mixture of 10ml 2% Lidocaine with 10ml 0.5 % Bupivacaine was administered to the superficial peroneal, deep peroneal, sural and saphenous nerves. Ankle tourniquet was employed in all procedures. The patients were contacted post operatively and completed a standardised questionnaire including an incremented pain assessment ranging from 0-10 (0 no pain, 10 severe pain). 17 female and 1 male patients were contacted (age range 33-67y). Procedures included 13 first metatarsal osteotomies, 3 cheilectomies, 2 first MTP joint replacements, and 5 fusions. 14 patients requested a short acting sedative (midazolam). 5 patients (27 %) reported some discomfort during the block procedure (average pain score 1.2). No patients reported any pain during their operation(s). 4 patients (22%) required supplementation of the block. Average pain score at 6, 12, 24 and 48 hours following surgery were 0.66, 2.9, 2.4 and 1.3 respectively. All patients were discharged home and walking on the same day. None complained of nausea or required parenteral analgesia; there were no readmissions. Each patient confirmed they would have surgery under local block rather than general anaesthesia and would recommend this technique to family and friends. Forefoot surgery under ankle block alone is safe and effective. Anaesthesia obtained permits the majority of forefoot procedures and provides lasting post-operative analgesia. Combined with intraoperative sedation, use of ankle tourniquet and same day discharge, it has very high patient acceptance and satisfaction.
A consensus regarding management of calcaneal fractures eludes orthopaedic surgeons. While operative treatment has gained more acceptance, surgical morbidity remains high. We undertook a retrospective review of early complications and radiological outcomes following internal fixation of calcaneal fractures in our unit over 15 months. A consecutive series of 33 patients who underwent fixation of the Calcaneus was selected. Patient records, X-rays and scans were reviewed. 37 fractures in 33 patients underwent fixation. 81 % were male. Mean age at surgery was 37yrs (19 -59yrs). 35 % were operated within 1 wk of injury and 13% after 2 wks of injury. 43% were Sanders' type III, 18% type II and 13% tuberosity avulsion fractures. 63% had a reversed/zero Bohler's angle. Mean post-op Bohler's angle was 32 degrees. Overall complication rate was 32%, with a combined deep infection rate of 8%. All patients with infection were male, and 70% were smokers. 86% were above 40yrs of age (mean 47yrs). The deep infection rate for intra-articular fractures was 3% and for tuberosity avulsion fractures 40%. Majority of patients with wound complications had been operated within 7 days of injury. Males over 40yrs and smokers seem to be at most risk of wound complications. Time to surgery/delay in surgery up to 2 wks did not seem to have any adverse consequences. Complications increase with fracture complexity and avulsion fractures have highest risk of wound breakdown. Near anatomical restoration of the articular surface is possible in most.
Outcomes following total ankle replacement (TAR) have been less favorable than hip and knee arthroplasty. The Mobility TAR is a newly introduced mobile bearing ankle prosthesis which, unlike its predecessor the Agility, does not require fusion of the tibiofibular syndesmosis which in theory should reduce the rate of early failure. No studies have been published yet reporting follow-up longer than 1 year after surgery with this prosthesis. From June 2006 to May 2008, 50 Mobility TARs were performed in our unit. Data have been collected prospectively on all 50 patients and all have been reviewed annually since surgery. Follow up ranges from one to three years. The mean age was 65 (range 35–79). 20 patients (40%) were male. 10 underwent additional concurrent procedures (six calcaneal osteotomies, one 1st metatarsal osteotomy, two lateral ligament reconstructions, one subtalar arthrodesis). There was one early wound breakdown which subsequently healed without causing deep infection. There were no malleolar fractures. In two prostheses the talar component has subsided over two years resulting in painful loosening. Interestingly both these patients had postraumatic osteoarthritis with a fibular malunion. Both have been listed for revision to arthrodesis. One further patient has a loose talar component without subsidence and is awaiting exploration with a view to revision. There was one deep infection presenting at 18 months. One further patient reports continued hindfoot pain, thought to be from the subtalar joint and is being worked up for arthrodesis. The mean American Orthopaedic Foot and Ankle Society scores (scale 10–100) increased from 30 to 69 scores following surgery. TAR using the Mobility prosthesis gives good early clinical results. Further follow-up studies are required to see if this performance is maintained in the long term.
Furthermore, the increasing incidence of multi-resistant bacteria is a concern to all. The Scottish Health Executive has identified the rationalisation of antibiotic prescribing as one of the principal means of reducing the development of these organisms.
In addition, Orthopaedic Consultants in the west of Scotland were contacted asking whether they use antibiotics in hallux valgus surgery and what their perception of infection risk was.
Thirty-five consultants replied, of which 15 regularly performed surgery for hallux valgus. Prophylactic antibiotics were used by seven, with the average perception of infection risk 4%.
Background: Since 2003 we have offered correction of bilateral hallux valgus to suitable patients as a daycase but there is nothing in the literature to support this as safe practice. Two published series support unilateral hallux valgus surgery as a daycase. We prospectively evaluated 30 bilateral daycase patients assessing complications and overall satisfaction rating.
