Aims. Achilles tendon re-rupture (ATRR) poses a significant risk of postoperative complication, even after a successful initial surgical repair. This study aimed to identify risk factors associated with Achilles tendon re-rupture following operative fixation. Methods. This retrospective cohort study analyzed a total of 43,287 patients from national health claims data spanning 2008 to 2018, focusing on patients who underwent surgical treatment for primary Achilles tendon rupture. Short-term ATRR was defined as cases that required revision surgery occurring between six weeks and one year after the initial surgical repair, while omitting cases with simultaneous infection or skin necrosis. Variables such as age, sex, the presence of Achilles tendinopathy, and comorbidities were systematically collected for the analysis. We employed multivariate stepwise logistic regression to identify potential risk factors associated with short-term ATRR. Results. From 2009 to 2018, the short-term re-rupture rate for Achilles tendon surgeries was 2.14%. Risk factors included male sex, younger age, and the presence of Achilles tendinopathy. Conclusion. This large-scale, big-data study reaffirmed known risk factors for short-term Achilles tendon re-rupture, specifically identifying male sex and younger age. Moreover, this study discovered that a prior history of Achilles tendinopathy emerges as an independent risk factor for re-rupture, even following initial operative fixation.

Aims. Tibiotalocalcaneal (TTC) fusion is used to treat a variety of conditions affecting the ankle and subtalar joint, including osteoarthritis (OA), Charcot arthropathy, avascular necrosis (AVN) of the talus, failed total ankle arthroplasty, and severe deformity. The prevalence of postoperative complications remains high due to the complexity of hindfoot disease seen in these patients. The aim of this study was to analyze the relationship between preoperative conditions and postoperative complications in order to predict the outcome following primary TTC fusion. Methods. We retrospectively reviewed the medical records of 101 patients who underwent TTC fusion at the same institution between 2011 and 2019. Risk ratios (RRs) associated with age, sex, diabetes, cardiovascular disease, smoking, preoperative ankle deformity, and the use of bone graft during surgery were related to the postoperative complications. We determined from these data which pre- and perioperative factors significantly affected the outcome. Results. Out of the 101 patients included in the study, 29 (28.7%) had nonunion, five (4.9%) required below-knee amputation (BKA), 40 (39.6%) returned to the operating theatre, 16 (15.8%) had hardware failure, and 22 (21.8%) had a postoperative infection. Patients with a preoperative diagnosis of Charcot arthropathy and non-traumatic OA had significantly higher nonunion rates of 44.4% (12 patients) and 39.1% (18 patients) (p = 0.016) and infection rates of 29.6% (eight patients) and 37% (17 patients) compared to patients with traumatic arthritis, respectively (p = 0.002). There was a significantly increased rate of nonunion in diabetic patients (RR 2.22; p = 0.010). Patients with chronic kidney disease were 2.37-times more likely to have a nonunion (p = 0.006). Patients aged over 60 years had more than a three-fold increase in the rate of postoperative infection (RR 3.60; p = 0.006). The use of bone graft appeared to be significantly protective against postoperative infection (p = 0.019). Conclusion. We were able to confirm, in the largest series of TTC ankle fusions currently in the literature, that there remains a high rate of complications following this procedure. We found that patients with a Charcot or non-traumatic arthropathy had an increased risk of nonunion and postoperative infection compared to individuals with traumatic arthritis. Those with diabetes, chronic kidney disease, or aged over 60 years had an increased risk of nonunion. These findings help to confirm those of previous studies. Additionally, our study adds to the literature by showing that autologous bone graft may help in decreasing infection rates. These data can be useful to surgeons and patients when considering, discussing and planning TTC fusion. It helps surgeons further understand which patients are at a higher risk for postoperative complications when undergoing TTC fusion. Cite this article: Bone Joint J. 2020;102-B(3):345–351

Aims. Surgical reconstruction of deformed Charcot feet carries a high risk of nonunion, metalwork failure, and deformity recurrence. The primary aim of this study was to identify the factors contributing to these complications following hindfoot Charcot reconstructions. Methods. We retrospectively analyzed patients who underwent hindfoot Charcot reconstruction with an intramedullary nail between January 2007 and December 2019 in our unit. Patient demographic details, comorbidities, weightbearing status, and postoperative complications were noted. Metalwork breakage, nonunion, deformity recurrence, concurrent midfoot reconstruction, and the measurements related to intramedullary nail were also recorded. Results. There were 70 patients with mean follow-up of 54 months (SD 26). Overall, 51 patients (72%) and 52 patients (74%) were fully weightbearing at one year postoperatively and at final follow-up, respectively. The overall hindfoot union rate was 83% (58/70 patients). Age, BMI, glycated haemoglobin, and prior revascularization did not affect union. The ratio of nail diameter and isthmus was greater in the united compared to the nonunited group (0.90 (SD 0.06) and 0.86 (SD 0.09), respectively; p = 0.034). In those with a supplementary hindfoot compression screw, there was a 95% union rate (19/20 patients), compared to 78% in those without screws (39/50 patients; p = 0.038). All patients with a miss-a-nail hindfoot compression screw went on to union. Hindfoot metalwork failure was seen in 13 patients (19%). An intact medial malleolus was found more frequently in those with intact metalwork ((77% (44/57 patients) vs 54% (7/13 patients); p = 0.022) and in those with union ((76% (44/58 patients) vs 50% (6/12 patients); p = 0.018). Broken metalwork occurred more frequently in patients with nonunions (69% (9/13 patients) vs 9% (5/57 patients); p < 0.001) and midfoot deformity recurrence (69% (9/13 patients) vs 9% (5/57 patients); p < 0.001). Conclusion. Rates of hindfoot union and intact metalwork were noted in over 80% of patients. Union after hindfoot reconstruction occurs more frequently with an isthmic fit of the intramedullary nail and supplementary hindfoot screws. An intact medial malleolus is protective against nonunion and hindfoot metalwork failure. Cite this article: Bone Joint J 2022;104-B(6):703–708

Aims

Calcaneal osteomyelitis remains a difficult condition to treat with high rates of recurrence and below-knee amputation, particularly in the presence of severe soft-tissue destruction. This study assesses the outcomes of single-stage orthoplastic surgical treatment of calcaneal osteomyelitis with large soft-tissue defects.

Aims

The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant.

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.

Aims

Although absorbable sutures for the repair of acute Achilles tendon rupture (ATR) have been attracting attention, the rationale for their use remains insufficient. This study prospectively compared the outcomes of absorbable and nonabsorbable sutures for the repair of acute ATR.

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.

Aim. To evaluate the clinical outcome of a new absorbable, gentamycin loaded calcium sulfate/hydroxyapatite biocomposite (CERAMENT. ™. /G) as cavity filler after debridement and removal of infected metalwork in chronic osteomyelitis. Methods. We report the retrospective study of prospectively collected data from 36 patients with chronic osteomyelitis from implant infection. Treatment included a single stage protocol with removal of the metalwork, debridement augmented with application of CERAMENT. ™. /G, stabilization, culture-specific antibiotics and primary skin closure or flap. The biocomposite was used for dead space filling after resection of Cierny-Mader (C-M) stage III and IV chronic osteomyelitis. Data were collected on patient age, comorbidities, operation details, microbiology, postoperative complications and type of fixation or plastic surgery. Primary measure of outcome was recurrence rate. Results. According to the C-M classification 22 patients (63%) were defined as Type III and 13 (37%) as Type IV. A total of 26 (72%) patients were Class B hosts. In 9 cases (25%), there was an infected non-union and 1 patient had septic arthritis. Mean age was 52 years (range 22 to 81). Patients were followed for a mean of 20 months (range 6 to 36). Infection was eradicated in 32 patients. There were three (8.3%) recurrences (two cases of osteomyelitis and one of soft tissue/flap infection). Two of them were successfully managed with repeat surgery (one Class B and one Class A host) and one (Class B host) with suppressive antibiotic therapy as per patient's choice. In one infected nonunion the infection was eradicated but the nonunion persisted. Thirteen patients (36.6%) had a local or free fascio-cutaneus flap. Staphylococci (50%) and Enterococci (15%) were the most common microorganisms. Pseudomonas aeruginosa was more common in polymicrobial infection usually with Staphylococcus aureus. Conclusions. A multidisciplicary approach including augmented debridement with CERAMENT. ™. /G is effective for treatment of chronic osteomyelitis with infected metalwork

Aims. Flexor hallucis longus (FHL) tendon transfer is a well-recognized technique in the treatment of the neglected tendo Achillis (TA) rupture. Patients and Methods. We report a retrospective review of 20/32 patients who had undergone transtendinous FHL transfer between 2003 and 2011 for chronic TA rupture. Their mean age at the time of surgery was 53 years (22 to 83). The mean time from rupture to surgery was seven months (1 to 36). The mean postoperative follow-up was 73 months (29 to 120). Six patients experienced postoperative wound complications. Results. The mean postoperative Achilles tendon Total Rupture Score (ATRS) was 83 (40 to 100) and the mean American Orthopaedic Foot & Ankle Society (AOFAS) score was 94.3 (82 to 100). Tegner scoring showed a mean reduction of one level from the pre-injury level of activity. There was a mean reduction of 24% (4 to 54) in dynamometer-measured strength of ankle plantarflexion, in comparison with the non-operated side. The hallux had a mean of only 40% (2 to 90) strength of plantarflexion in comparison with the contralateral side. Conclusion. We conclude that transtendinous FHL transfer for neglected TA ruptures, with a long harvest to allow reattachment of the triceps surae, provides reliable long-term function and good ankle plantarflexion strength. Despite the loss of strength in hallux plantar flexion, there is little comorbidity from the FHL harvest. Cite this article: Bone Joint J 2018;100-B:584–9

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.

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

Aims

The hypothesis of this study was that bone peg fixation in the treatment of osteochondral lesions of the talus would show satisfactory clinical and radiological results, without complications.

Introduction:. Techniques devised for 1. st. MTPJ arthrodesis have been described since 1979 when Humbert et al published a ‘tongue and trough’ technique. Common contemporary techniques include fixation with single or crossed screws, or dorsal plates and these are suitable for a variety of indications. All three contemporary techniques have demonstrated a wide range of fusion rates. This study reports a comparison of non-union rates of the 1. st. metatarsophalangeal joint (MTPJ) with the current Memometal Anchorage™ dorsal plate system and the previous Hallu-fix™ and Charlotte™ systems. Methods:. Between 01/2009 and 07/2012 174 consecutive 1. st. MTPJ fusions were performed for 153 patients (Mean age 62, range 42 to 83) by three surgeons at one University teaching hospital. 40 patients (23%) were male and 132 (77%) female. Patients without available radiographs were excluded from the study. 20 patients received Hallu-fix™ plates, 76 Charlotte™ plates and 76 Memometal Anchorage™. Radiographs of the feet were taken from four weeks postoperatively and reviewed for incomplete bone bridging and increased radiolucency around screws. Results:. 12 (7.0%) non-unions were identified in total during followup. A single (5.0%) Hallu-fix™ system, 9 (11.8%) Charlotte™ systems and 2 (2.6%) Memometal Anchorage™ plating systems did not develop a satisfactory fusion. Typical followup in patients in whom there were no postoperative complications and who developed satisfactory bony union was 12 weeks. Those with non-unions were followed until revision procedures were successful. Conclusion:. The total non-union rate of this centre during the period compares favourably with published literature suggesting the technique is suitable for numerous indications in 1. st. MTPJ fusion. With a non-union rate of 5.0%, the Hallu-fix™ shows favourable results when compared authors using the same system. The Charlotte™ system demonstrated an 11.8% non-union rate, comparing poorly with published literature. The Memometal Anchorage™ system, with a non-union rate of 2.6%, demonstrated promising results

Introduction. The delayed presentation of Achilles tendon rupture is common, and is a difficult problem to manage. A number of surgical techniques have been described to treat this problem. We describe the use of Flexor Hallucis Longus (FHL) transfer to augment the surgical reconstruction of the delayed presentation of achilles tendon rupture. Materials and Methods. Fourteen patients with chronic tendo-Achilles rupture, presenting between April 2008 and December 2010, underwent surgical reconstruction and FHL transfer. Surgery was performed employing standard operative techniques, with shortening of the Achilles tendon and FHL transfer into the calcaneum with a Biotenodesis screw (Arthrex). VISA-A scores were performed preoperatively and six months postoperatively. Complication data was collected by review of the electronic patient record and direct patient questioning. Results. One patient died of an unrelated cause shortly before outcome scoring, and another patient was excluded because casting in the preoperative period prevented accurate scoring, although he achieved a good post-treatment score. Analysis was therefore carried out on twelve patients. Eleven of the twelve patients had significant improvement in their VISA-A score, with a mean improvement in score of 30 (p < 0.05). There were no significant complications in any of the patients. Conclusion. Our results show that FHL transfer in the management of chronic Achilles tendon rupture is a good, safe and reliable technique. There is excellent improvement in the mean VISA-A score, with no significant complications. Our results support the use of FHL tendon transfer for patients with chronic tendo-Achilles rupture

Aims

The aim of this study was to evaluate the functional outcome in patients undergoing implant removal (IR) after fracture fixation below the level of the knee.

Aims

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

Aims

Total ankle arthroplasty (TAA) surgery is complex and attracts a wide variety of complications. The literature lacks consistency in reporting adverse events and complications. The aim of this article is to provide a comprehensive analysis of each of these complications from a literature review, and to compare them with rates from our Unit, to aid clinicians with the process of informed consent.
