Background

The use of a knotless TightRope for the stabilisation of a syndesmotic injury is a well-recognised mode of fixation. It has been described that the device can be inserted using a “closed” technique. This presents a risk of saphenous nerve entrapment and post-operative pain.

Aim

We aimed to establish the actual risk of injury to the Saphenous Nerve using a “closed” technique for the insertion of a TightRope.

Introduction. Minimally invasive Achilles tendon repair has recently gained popularity amongst foot and ankle surgeons. This study aims to quantify the risk of sural nerve injury when using the Achillon device (Integra), as well as delineate its anatomical relationship to the Achilles tendon. Methods. In 15 cadaveric specimens, the Achilles tendon was transected through a 2cm transverse incision made 4cm proximal to the palpable Achilles tendon insertion point. The Achillon device was inserted beneath the paratenon both proximally and distally and six needle passers mounted with sutures were introduced percutaneously into the tendon (x3 proximal and x3 distal). We dissected around the Achillon jig to determine whether the needle and suture had punctured the sural nerve. We also documented the position of the sural nerve in relation to the Achilles tendon. Results. The mean horizontal distance from the Achilles tendon insertion to the sural nerve was 22.5mm (15.9mm–30.2mm). The mean vertical distance from the Achilles tendon insertion to the point where the sural nerve crosses the lateral border of the tendon was 96.1mm (77.4mm–134.9mm). In 4 out of 15 cadaveric specimens (27%) the sural nerve was punctured. In total, the sural nerve was punctured 6 times (twice in 2 specimens) in 90 needle passes (6.7%). Five out of the 6 punctures occurred when the Achillon device was inserted into the distal tendon portion with the most proximal hole being responsible for 3 of the punctures. Conclusions. The sural nerve displays a highly variable anatomical course and our findings highlight a significant risk of puncture during percutaneous Achilles tendon repair using the Achillon device. More studies are needed to clarify whether this risk equates to a significant clinical problem and whether a change in technique or instrumentation can decrease this risk

Background. Open subtalar arthrodesis has been associated with a moderate rate of non-union, as high 16.3%, and high rates of infection and nerve injury. Performing this operation arthroscopically serves to limit the disruption to the soft tissue envelope, improve union rates and reduce infection. Our study describes our outcomes and experience of this operation. Method. Retrospective review of all patients who underwent an arthroscopic subtalar arthrodesis between 2023 and 2008. We excluded patients undergoing concurrent adjacent joint arthrodesis. The primary aim was to report on rates of union. Secondary outcomes included reporting on conversion to open procedure, duration of surgery, infection, and iatrogenic injury to surrounding structures. Results. 135 patients were included in the final analysis. 129 patients (95.5%) achieved union. The median time to fusion was 98 days. All cases were performed through sinus tarsi portals. 38 cases were performed with an additional posterolateral portal. Most cases (107/77%) were performed with 2 screws. 3 cases (2.2%) were converted to open procedures. The median tourniquet time was 86 minutes but available in only 88 (65%) cases. There were 4 (2.9%) superficial infections and no deep infections. 1 patient sustained an injury to FHL and there were no reported nerve injuries. Conclusions. At present this is the largest series of arthroscopic subtalar arthrodeses. We demonstrate that this operation can achieve high rates of union with low rates of infection with an equally low likelihood of needing to convert to an open procedure with modest operative times. In our experience the addition of a posterolateral portal does not appear to increase the incidence of nerve injury and aids in the visualisation of all 3 facets

Lateral approach open calcaneal osteotomy is the described gold standard procedure in the management of hindfoot deformity. With development of minimally invasive surgery, a MIS approach has been described, citing fewer wound complications and lower risk of sural nerve injury. This audit compares MIS to the traditional procedure. A retrospective review of all patients undergoing calcaneal osteotomy in Northumbria Trust in the past 5 years was performed. A total of 105 osteotomies were performed in 97 patients; 28 (13M:15F) in MIS group and 77 (40M:37F) had an open approach. The average age was 52.1 (range 16–83) for MIS and 51.5 (range 18–83) in the open group. All patients were followed up for development of wound complication, nerve injury and fusion rate. Wound complications were similar (10.7% in MIS group vs 10.3% in Open group) with no significant difference (p=0.48). Patients were treated for infection in 3(3.8%) cases in the open group and 2(7.1%) in the MIS group. This difference was not significant (p=0.43). 4 (14.3%) patients in the MIS group had evidence of sural nerve dysfunction post-operatively (managed expectantly), compared to 12(15.5%) patients in the open group (p=0.44). Of these, 2 went on to undergo neuroma exploration. There was no difference in nerve dysfunction in varus or valgus correction. Mean translation in the open group was measured as 7.3mm(SD=1.91;3 to 13mm) and 7.5mm(SD=1.25;5 to 10mm) in the MIS group. Translation was similar in varus or valgus correction. Non-union occurred in 2 patients in the MIS group and none in the open group (p= 0.06). MIS calcaneal osteotomy is a safe technique, that works as effectively as osteotomy performed through an open approach. There were lower rates of nerve injury, wound complication and infection, but this was not significantly different comparing groups. There was a higher risk of non-union in MIS technique

Aims. The optimal management of posterior malleolar ankle fractures, a prevalent type of ankle trauma, is essential for improved prognosis. However, there remains a debate over the most effective surgical approach, particularly between screw and plate fixation methods. This study aims to investigate the differences in outcomes associated with these fixation techniques. Methods. We conducted a comprehensive review of clinical trials comparing anteroposterior (A-P) screws, posteroanterior (P-A) screws, and plate fixation. Two investigators validated the data sourced from multiple databases (MEDLINE, EMBASE, and Web of Science). Following PRISMA guidelines, we carried out a network meta-analysis (NMA) using visual analogue scale and American Orthopaedic Foot and Ankle Score (AOFAS) as primary outcomes. Secondary outcomes included range of motion limitations, radiological outcomes, and complication rates. Results. The NMA encompassed 13 studies, consisting of four randomized trials and eight retrospective ones. According to the surface under the cumulative ranking curve-based ranking, the A-P screw was ranked highest for improvements in AOFAS and exhibited lowest in infection and peroneal nerve injury incidence. The P-A screws, on the other hand, excelled in terms of VAS score improvements. Conversely, posterior buttress plate fixation showed the least incidence of osteoarthritis grade progression, postoperative articular step-off ≥ 2 mm, nonunions, and loss of ankle dorsiflexion ≥ 5°, though it underperformed in most other clinical outcomes. Conclusion. The NMA suggests that open plating is more likely to provide better radiological outcomes, while screw fixation may have a greater potential for superior functional and pain results. Nevertheless, clinicians should still consider the fragment size and fracture pattern, weighing the advantages of rigid biomechanical fixation against the possibility of soft-tissue damage, to optimize treatment results.

Aim. 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. Method. 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. Results. 12 right and 6 left ankle replacements were revised in 17 patients (11 male/ 6 female). The mean age at revision was 69.1 years (range 56–81 years) with a mean BMI of 31. The mean surgical time was 171 minutes with 22% of cases requiring bone grafting. 6 patients had early wound complications, all superficial and settled with dressings. There were no deep infections, 2 patients had further surgery for exploration for possible nerve injuries. At a mean follow up of 20.6 months, 4 patients had mild/moderate ongoing pain with the majority of patients being satisfied with the outcome of their surgery. Conclusion. This study represents one of the largest group of patients reported to have undergone revision total ankle arthroplasty. Our experience shows that this results in acceptable level of complications and provides satisfactory function in most patients. We feel revision TAR is a viable option in patients with failed primary arthroplasty who wish to continue to maintain mobility at the ankle joint

Traditional open approaches for subtalar arthrodesis have reported nonunion rates of 5–16% and significant incidence of infection and nerve injury. The rationale for arthroscopic arthrodesis is to limit dissection of the soft tissues in order to preserve blood supply for successful fusion, whilst minimising the risk of soft tissue complications. The aim of this study was to determine the outcomes of sinus tarsi portal subtalar arthrodesis. Case records of all patients undergoing isolated arthroscopic subtalar arthrodesis by two senior surgeons between 2004 and 2014 were examined. All patients were followed up until successful union or revision surgery. The primary outcome measure was successful clinical and radiographic union. Secondary outcome measures included occurrence of infection and nerve injury. Seventy-seven procedures were performed in 74 patients, with successful fusion in 75 (97.4%). One (1.3%) superficial wound infection and one (1.3%) transient sural nerve paraesthesia occurred. Fixation with a single screw provided sufficient stability for successful arthrodesis. To our knowledge this is the largest reported series of isolated arthroscopic subtalar arthrodeses to date, and the first series reporting results of the two portal sinus tarsi approach. This approach allows access for decortication of all three articular facets, and obviates the need for a posterolateral portal, features which may explain the high union rate and low incidence of sural nerve injury in our series

Introduction. Flexor Hallucis Longus (FHL) tendon transfer is a well-recognised salvage operation for irreparable tendon Achilles (TA) ruptures and intractable Achilles tenonopathy. Several case series describes the technique and results of arthroscopic FHL tendon transfers. We present a comparative case series of open and arthroscopic FHL tendon transfers from Southmead Hospital, Bristol, UK. Methods. For the arthroscopic FHL transfers in most cases the patients were positioned semi prone with a tourniquet. A 2 or 3 posterior portal technique was used and the tendon was secured using an RCI screw. The rehabilitation was similar in both groups with 2 weeks in an equinus backslab followed by gradual dorsiflexion in a boot over the following 6 weeks. Anticoagulation with oral aspirin for 6 weeks was used. A retrospective case note review was performed. Results. There were 12 arthroscopic (8 males, 4 female) and 16 open procedures (9 male, 7 female). Both had a mean age of 56. 1 arthroscopic FHL was lost to follow up. There were no concomitant procedures in the arthroscopic group. In the open group the TA was repaired in 7 cases (3 of these involved z-shortening). There was 1 plantaris interposition, 1 V-Y advancement and 1 gastrocnemius advancement. Degenerate tendon was excised in 1 severe re-rupture of a calcified tendinopathic achilles. There was no difference in tourniquet time between the groups (arthroscopic 69mins vs open 64 mins, p=0.64). There were no complications in the arthroscopic group. In the open group there was 1 superficial wound infection, 1 nerve injury & 1 delayed DVT at 3 months. Conclusion. Arthroscopic FHL transfer is a safe and effective surgical option when no other achilles procedures are required. The soft tissue insult is minimal, making it a good option for patients with poor soft tissues or neurovascular compromise

Aims

A local injection may be used as an early option in the treatment of Morton’s neuroma, and can be performed using various medications. The aim of this study was to compare the effects of injections of hyaluronic acid compared with corticosteroid in the treatment of this condition.

Methods

A total of 91 patients were assessed for this trial, of whom 45 were subsequently included and randomized into two groups. One patient was lost to follow-up, leaving 22 patients (24 feet) in each group. The patients in the hyaluronic acid group were treated with three ultrasound-guided injections (one per week) of hyaluronic acid (Osteonil Plus). Those in the corticosteroid group were treated with three ultrasound-guided injections (also one per week) of triamcinolone (Triancil). The patients were evaluated before treatment and at one, three, six, and 12 months after treatment. The primary outcome measure was the visual analogue scale for pain (VAS). Secondary outcome measures included the American Orthopaedic Foot and Ankle Society (AOFAS) score, and complications.

Introduction. Active patients may benefit from surgical repair of the achilles tendon with the aim of preserving functional length and optimising push-off power. A mini-open device assisted technique has the potential to reduce wound complications, but risks nerve injury. We present the largest published series of midsubstance achilles tendon repairs using the Achillon® device. Methods. A prospective cohort study was run at the Princess Royal Devon & Exeter Hospital between 2008 and 2015. We included all patients who presented with a midsubstance Achilles tendon rupture within 2 weeks of injury, and device assisted mini-open repair was offered to a young active adult population. All patients in the conservative and surgical treatment pathway had the same functional rehabilitation protocol with a plaster for 2 weeks, and a VACOped boot in reducing equinus for a further 8 weeks. Results. 354 patients presented with a midsubstance achilles tendon rupture over a 7-year period, of which 204 had conservative treatment and 150 patients had surgical repair with the Achillon device. Patients were assessed clinically for a minimum of 10 weeks, with long-term notes surveillance for late complications. The rerupture rate for conservative treatment was 1.5%, with no reruptures in the Achillon group. Infections in the surgical group were superficial in 2 cases (1.3%) and deep in 3 cases (2%). Pulmonary embolus occurred in 2 Achillon cases (1.3%), and 1 conservatively managed case (0.5%). There was 1 case of temporary sural nerve irritation in each group. Discussion. Our series show encouraging results for the Achillon® repair with no reruptures and a low complication profile. Functional rehabilitation is likely to have contributed to the low rerupture rate. Studies are emerging that show earlier and improved calf muscle strength in those having surgical repair, suggesting a role for device assisted mini open repair in a selected population

Aims

Treatment for delayed wound healing resulting from peripheral vascular diseases and diabetic foot ulcers remains a challenge. A novel surgical technique named ‘tibial cortex transverse transport’ (TTT) has been developed for treating peripheral ischaemia, with encouraging clinical effects. However, its underlying mechanisms remain unclear. In the present study, we explored the potential biological mechanisms of TTT surgery using various techniques in a rat TTT animal model.

Methods

A novel rat model of TTT was established with a designed external fixator, and effects on wound healing were investigated. Laser speckle perfusion imaging, vessel perfusion, histology, and immunohistochemistry were used to evaluate the wound healing processes.

Introduction. The aim of this study is to better understand the anatomy of the forefoot to minimise surgical complications following minimally invasive forefoot surgery. Methods. The study examines the plantar anatomy of the lesser toes in ten cadaver feet. The tendons, nerves and bony anatomy are recorded. Results. The anatomy of the flexor tendons reveals the short flexor tendon bifurcates to allow the long flexor tendon to pass through it reliably at the level of the metatarsophalangeal joint (MTPJ) in the lesser rays. The division of the intermetatarsal nerves to digital nerves relative to the MTPJ is more variable. This nerve division is more consistently related to the skin of the web between the toes. In the first webspace the division is on average 3cm proximal to the skin at the deepest part of the cleft. In the second, third and fourth webspaces this distance is reduced to 1cm. The level of the deepest part of the webspace to the MTPJ is also variable. Discussion. Surgical release of the flexor tendons is recommended just proximal to the MTPJ for releasing both tendons and distal to the proximal interphalangeal joint for the long flexor tendon. The webspace skin and MTPJ's are easily identifiable landmarks clinically and radiologically. Awareness of the intermetatarsal nerve division will help to reduce nerve injuries with minimally invasive surgery to the plantar forefoot

Aims

The ideal management of acute syndesmotic injuries in elite athletes is controversial. Among several treatment methods used to stabilize the syndesmosis and facilitate healing of the ligaments, the use of suture tape (InternalBrace) has previously been described. The purpose of this study was to analyze the functional outcome, including American Orthopaedic Foot & Ankle Society (AOFAS) scores, knee-to-wall measurements, and the time to return to play in days, of unstable syndesmotic injuries treated with the use of the InternalBrace in elite athletes.

Methods

Data on a consecutive group of elite athletes who underwent isolated reconstruction of the anterior inferior tibiofibular ligament using the InternalBrace were collected prospectively. Our patient group consisted of 19 elite male athletes with a mean age of 24.5 years (17 to 52). Isolated injuries were seen in 12 patients while associated injuries were found in seven patients (fibular fracture, medial malleolus fracture, anterior talofibular ligament rupture, and posterior malleolus fracture). All patients had a minimum follow-up period of 17 months (mean 27 months (17 to 35)).

Minimally invasive chevron and akin osteotomy are being used in a few centres in the UK. The purpose of our study was to analyse our early results and present our early experience of minimally invasive chevron and akin osteotomy (MICA) for the correction of mild to moderate hallux valgus. This study assessed the radiological and clinical measurements, American Orthopaedic Foot and Ankle Society (AOFAS) scores, pain scores and patient satisfaction associated with performance of the MICA, for the treatment of hallux valgus. Between September 2010 and April 2012, 96 consecutive patients (122 feet) who underwent MICA were assessed. The overall satisfaction rate was over 90%. The mean total AOFAS score was 89.7 points. VAS for pain reduced from a mean of 7.4 to less than 1 point. On weight bearing anterior-posterior foot radiographs there was a significant improvement in the mean IMA and HVA. Complications included 2 episodes of superficial infection (1.6%), 1 fracture (0.8%), 4 incidence of nerve injury (3.3%) (Numbness) and 9 patients requiring removal of screw (7.4%). However, these screw removals occurred early on in the study and diminished after a slight modification in surgical technique. Based on our findings we concluded that MICA is an effective procedure with good patient satisfaction in the treatment of mild to moderate hallux valgus

The percutanous repair of the Achilles tendon is a cost efficient method of restoring early limb function and may offer reduced risk of re-rupture and wound infection. This technique has been described in the elderly population and elite athletes; we present an evaluation of this technique in a District General Hospital setting. We have prospectively audited the outcome of 56 patients who have elected to have percutaneous repair for Achilles tendon rupture from 2009–2011. The majority were males (44) with mean age of 46 years (range 27–80). Twenty nine patients ruptured the right tendon and 27 the left. 82% (46) of injuries were sustained whilst exercising: e.g. football (22), badminton (7), running (5). All but 2 patients were managed on a Day Case basis and 4 requested general anaesthesia. Patients were immediately weight bearing in a brace following surgery and commenced physiotherapy at 2 weeks. Functional outcome was measured using a modified Achilles Tendon Rupture Score (ATRS) at 3, 6, 9 and 12 months: 100 score equals maximal limitation. The mean ATRS scores a 3, 6, 9 and 12 months were 53 (7–82), 31 (0–74), 30 (0–67) and 15 (1–52) respectively. We have had 4 complications: 2 sural nerve injuries, 1 poor wound healing and 1 re-rupture at 8 weeks. Overall complication rate was 7.1%, comparable to other studies. We have shown a good outcome following percutaneous Achilles tendon repair. The majority of patients show good restoration of function by 3 months and a minor limitation at 6 months. The majority of the improvement in function occurred between 3 and 6 months following surgery. Two patients reported ongoing tendinopathic pain following repair increasing mean scores. We believe this technique can be introduced in District General Hospitals to give good outcome on a cost effective basis

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

Aims

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

Methods

The preparation steps for ankle arthroplasty were performed using the Infinity total ankle system in five right-sided cadaveric ankles. All tibial guide pins were intentionally inserted past the posterior tibial cortex for assessment. All posterior ankles were subsequently dissected, with the primary endpoint being the presence of direct contact between the structure and pin.

Aims

This is a multicentre, non-inventor, prospective observational study of 503 INFINITY fixed bearing total ankle arthroplasties (TAAs). We report our early experience, complications, and radiological and functional outcomes.

Methods

Patients were recruited from 11 specialist centres between June 2016 and November 2019. Demographic, radiological, and functional outcome data (Ankle Osteoarthritis Scale, Manchester Oxford Questionnaire, and EuroQol five-dimension five-level score) were collected preoperatively, at six months, one year, and two years. The Canadian Orthopaedic Foot and Ankle Society (COFAS) grading system was used to stratify deformity. Early and late complications and reoperations were recorded as adverse events. Radiographs were assessed for lucencies, cysts, and/or subsidence.

Aims

Functional rehabilitation has become an increasingly popular treatment for Achilles tendon rupture (ATR), providing comparably low re-rupture rates to surgery, while avoiding risks of surgical complications. Limited evidence exists on whether gap size should affect patient selection for this treatment option. The aim of this study was to assess if size of gap between ruptured tendon ends affects patient-reported outcome following ATR treated with functional rehabilitation.

Methods

Analysis of prospectively collected data on all 131 patients diagnosed with ATR at Royal Berkshire Hospital, UK, from August 2016 to January 2019 and managed non-operatively was performed. Diagnosis was confirmed on all patients by dynamic ultrasound scanning and gap size measured with ankle in full plantarflexion. Functional rehabilitation using an established protocol was the preferred treatment. All non-operatively treated patients with completed Achilles Tendon Rupture Scores (ATRS) at a minimum of 12 months following injury were included.
