Abstract
PURPOSE To investigate the clinical efficacy of arthrodesis performed through anterior and lateral approaches for ankle arthritis treatment. METHODS A retrospective analysis of the clinical data of 86 patients with ankle arthritis treated with ankle arthrodesis between January 2019 and December 2022 was conducted. According to the inclusion and exclusion criteria, 65 patients were ultimately included. The ankle osteoarthritis score (AOS), the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scoring system, and alignment changes (medial distal tibial angle (MDTA), anterior distal tibial angle (ADTA), and Talus tilt angle (TTA)) were used to evaluate ankle function before surgery and at the last follow-up. RESULTS Throughout the follow-up period, there were no significant differences between the two groups in terms of age, sex, operation time, average union time, union rate, total complication rate, or incidence of various types of complications. The AOSs were as follows: anterior approach group, preoperative 57.61 ± 3.64; last follow-up, 19.34 ± 2.19; lateral approach group, preoperative 56.62 ± 3.49; and last follow-up, 19.76 ± 2.39. The AOFAS scores were as follows: anterior approach group, preoperative 38.64 ± 2.52; last follow-up, 79.75 ± 4.85; lateral approach group, preoperative 37.33 ± 2.18; and last follow-up, 80.00 ± 3.70. Both patient groups exhibited good therapeutic effects before and after treatment, and there were no significant differences in the AOSs or AOFAS scores between groups at the last follow-up. Both patient groups exhibited significant changes in MDTA, TTA, and ADTA before and after treatment, and there were no significant differences between groups at the last follow-up. The preoperative TTA (5.02 ± 2.67) of the anterior approach group was smaller than that of the lateral approach group (14.28 ± 5.08), and the difference in TTA correction after different surgical approaches was significant, with the lateral approach treatment being more effective for TTA correction. CONCLUSION Both the anterior approach and the lateral approach for the treatment of ankle arthritis can achieve good therapeutic effects, with no significant differences in complications between the two methods, and the lateral approach has good therapeutic efficacy for varus ankle arthritis greater than 10 degrees.

Abstract
Background There is growing focus on surgical costs related to common orthopaedic procedures. In this investigation, we studied surgical costs associated with tibiotalar arthrodesis. Methods Patients were retrospectively identified who had undergone primary fusion of the tibiotalar joint based on Current Procedural Terminology (CPT) codes from 2014 to 2020. Using the Value Driven Outcome (VDO) tool, we conducted an evaluation of both total direct costs and facility-related expenses. The VDO tool encompasses a comprehensive item-level database capable of capturing detailed cost information, which is subsequently presented as relative mean data. Adjustments were made to cost variables to reflect 2022 US dollars, and comparative multivariable analysis of costs in relation to treatment groups adjusting for demographic variables was performed using generalized linear models to yield cost ratios along with 95% CIs. Results Our cohort consisted of 262 patients who underwent primary ankle fusion procedures done by one of 4 fellowship-trained orthopaedic foot and ankle surgeons. There were no differences in demographic data or total operating room (OR) time based on surgical construct (screws-alone n = 228 vs anterior plate-screws n = 34). Total direct costs for anterior plate-screw constructs were 78% higher than screws alone (ratio in cost = 1.78, 95% CI 1.55-2.08, P < .001), adjusting for other variables. For all fusion constructs, every 1-hour increase in total OR time increased total direct costs by 29% (ratio in cost = 1.29, 95% CI 1.18-1.40, P < .001). Conclusion Enhancing cost-effectiveness of orthopaedic care remains an important objective. Our investigation found that anterior plate-screw constructs for tibiotalar arthrodesis have notably higher total costs compared with screw-only constructs. Many variables are considered when selecting surgical constructs for ankle arthrodesis. When clinically appropriate, screw-only ankle arthrodesis constructs could be considered if there is a need to reduce costs. Level of Evidence Level III, retrospective comparative study.

Abstract
Background End-stage ankle arthritis is successfully treated with surgery with either ankle arthrodesis (AA) or total ankle arthroplasty (TAA). Much is described comparing the 2 treatments in tightly selected patient groups. Limited evidence attempts to examine specific elements of technical complexity that increase perioperative risk for the surgical treatment of ankle arthritis. There is suspicion that AA may be preferable in the setting of elevated patient complexity, or that procedures may require staging to diminish complication risk when there is also foot deformity present. The aim of this study is to evaluate the effect of adjunctive procedures on overall postoperative complication (POC) risk, for both TAA and AA. Primary outcome measures were to compare overall complication and reoperation risk for TAA and AA. Secondary outcome measures were to identify patient factors, intraoperative factors, and factors of procedural complexity via number of associated surgeries and the incidence of complications and reoperation. Methods A retrospective chart review of AAs and TAAs performed at a single academic institution from the years 2008-2024 was performed using Current Procedural Terminology (CPT) codes identifying AA and TAA. Patient demographics, operative details, and postoperative data were abstracted to collect relevant information. Statistical analyses, including odds ratios and analysis of variance, were then performed to reveal specific risk factors and correlations. Results Four hundred ninety-one patients were identified in the initial database query. After exclusions, 246 remained, of which 110 underwent AA and 136 underwent TAA. The mean length of follow-up was 36.4 months for TAA patients and 46.1 months for AA patients in this study. Overall, patients who underwent TAA were older and had an increased number of preoperative comorbidities (5.74 ± 3.07) compared to AA (4.74 ± 2.76) (P = .008). Additionally, TAA patients experienced a lower overall rate of POCs (20/136, 14.71%) and reoperation (14/136, 10.29%) compared with patients who underwent AA (21/110, 19.09%; 21/110, 19.09%) (P = .36 and P = .05, respectively). As the number of adjunctive procedures increased, so did the rate of POCs, but not reoperation, in patients who underwent TAA. The number of adjunctive procedures was not significantly associated with complication or reoperation risk in AA patients. There were no specific adjunctive procedures that demonstrated a significant correlation with increased risk of complications or reoperation in both groups. Osteoporosis and coagulopathies were identified as predisposing TAA patients to postoperative complications. Conclusion In our retrospective cohort study with relatively low statistical power, we found that patients who undergo TAA or AA plus adjunctive procedures did not experience an increased risk of major complications or reoperation compared to patients who did not undergo adjunctive procedures. Several preexisting comorbidities in TAA patients were associated with higher rates of POCs or reoperation, including osteoporosis and coagulopathies; no comorbidities were linked to increased reoperation or POC risk in the AA group. These findings suggest a need to evaluate comorbidities, and lifestyle factors when recommending an ankle reconstruction procedure to minimize the odds of postoperative complications and improve likelihood of patient satisfaction. Level of Evidence Level III, retrospective cohort study.

Abstract
BACKGROUND Ankle arthrodesis is the most frequently performed salvage procedure for pyogenic arthritis. However, its failed fusion rate of approximately 15% has been considered problematic. Herein, we present a case of pyogenic ankle arthritis successfully treated via a two-stage surgical procedure on the basis of the induced membrane technique. CASE PRESENTATION A 43-year-old Japanese male patient with alcoholic liver disease was referred to our institution. He complained of persistent ankle pain and local heat following osteosynthesis for a closed pilon fracture. Radiological examinations revealed massive destruction of the ankle joint. Cultures of samples obtained from the joint isolated Streptococcus viridans. On the basis of these findings, he was diagnosed with pyogenic ankle arthritis with osteomyelitis of the distal tibia and talus. We performed the two-stage procedure per the induced membrane technique. In the first stage, the necrotic and infected tissue was debrided, and a polymethylmethacrylate spacer was inserted into the bone defect. Intravenous antibiotics were administered for 1 week thereafter. In the second stage, which was performed 5 weeks after the first stage, the induced membrane was identified around the polymethylmethacrylate spacer and cut to remove the latter. Ankle arthrodesis was performed with three double-thread screws. Finally, the autologous cancellous bone graft harvested from the ipsilateral iliac crest was used to fill the bone defect. During the postoperative period, antibiotics were administered intravenously for 2 weeks. Blood examinations normalized 3 weeks after the second stage. The immobilization splint was maintained for 6 weeks, after which partial weight bearing was started, and 6 months after surgery, the patient returned to full weight bearing and walked confidently without ankle pain. Radiological evaluations performed 2 years after the second stage revealed complete consolidation, and he reported no pain while walking. CONCLUSION Ankle arthrodesis performed via the induced membrane technique not only successfully controlled infection, but also achieved complete bone union, enabling the preservation of ankle joint. This technique demonstrates its potential as a highly effective approach for treating pyogenic ankle arthritis.

Abstract
Ankle osteoarthritis (OA) is less common than knee and hip OA, and 75% to 80% of all presentations are posttraumatic in nature, resulting from either ligamentous or bony injury to the ankle. While the ankle joint cartilage demonstrates capacity for self-restoration, the ankle joint is sensitive to aberrancies in biomechanics and the inflammatory milieu after an injury is thought to contribute to the onset of posttraumatic ankle OA. Conservative care for ankle OA is currently centered on pain reduction, and derivatives that may delay the progression of ankle OA are the subject of ongoing investigation. Surgical management for end-stage ankle OA currently focuses on ankle arthrodesis and total ankle arthroplasty. Specific indication for one procedure over the other is the topic of much debate. While total ankle arthroplasty has become more frequently used with the advent of newer generation systems, ankle arthrodesis may still be favored in younger patients with high-demand occupations.

Sci Rep 2023; 13:18614. [PMID: 37903965 PMCID: PMC10616077 DOI: 10.1038/s41598-023-46034-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 10/26/2023] [Indexed: 11/01/2023] Open
Abstract
Ankle arthrodesis is commonly performed to treat end-stage ankle osteoarthritis. The aim of this study was to determine whether the use of fibular autograft might increase the fusion rate and decrease the complication rate in ankle arthrodesis (AA) fixed using cannulated screws. To perform this PRISMA-compliant proportional meta-analysis, multiple databases were searched for studies in which patients undergone AA (using exclusively cannulated screws and augmented with fibular bone graft) were followed. The characteristics of the cohort, the study design, surgical details, the nonunion and complication rate at the longest follow-up were extracted and recorded. The modified Coleman Methodology Score (mCMS) was applied to appraise the quality of studies. Two groups were built: arthrodeses fixed with screws combined with cancellous autograft (G1) and arthrodeses fixed with screws combined with cancellous autograft and augmented with a lateral fibular onlay (G2). A third group (arthrodeses fixed with screws and no graft, G3) was extracted from previous literature for a further comparison. Overall, we included 306 ankles (296 patients) from ten series (ten studies). In G1 and G2 there were 118 ankles (111 patients) and 188 ankles (185 patients), respectively. In patients where cancellous autograft was used, a further augmentation with a fibular lateral strut autograft did not change significantly the nonunion (4% [95% CI 1-9] in G1 vs. 2% [95% CI 0-5) in G2, p = 0.99) nor the complication rate (18% [95% CI 0-36] in G1 vs. 13% [95% CI 6-21) in G2, p = 0.71). Upon comparison with 667 ankles (659 patients, G3) in which arthrodeses had been performed without grafting, the nonunion and complication rates did not differ significantly either (pooled estimates: 3% [95% CI 1-3) in G1 + G2 vs. 3% [95% CI 2-4] in G3, p = 0.73 for nonunion; 15% [8-23] in G1 + G2 vs. 13% [95% CI 9-17] in G3, p = 0.93 for complications). In ankle arthrodesis fixed with cannulated screws combined with cancellous autograft at the fusion site, a construct augmentation with a distal fibular onlay strut graft positioned laterally at the ankle joint does not reduce the risk of nonunion or complication. In general, the use of bone graft does not influence significantly the nonunion nor the complication rate as compared to non-grafted screw-fixed ankle arthrodeses.Kindly check and confirm the corresponding author mail id is correctly identified.It's all correct.

Abstract
Background Osteoarthritis of the ankle, which has a prevalence of 3.4% in the general population and affects 70% of candidates post-traumatically, is less common than hip or knee arthritis. Despite the recent progress in ankle arthroplasty surgery, ankle arthrodesis is still considered the gold-standard treatment for severe osteoarthritis of the ankle joint and can achieve impressive improvements in pain and function in the majority of patients. Our objective is to assess the clinical and functional outcomes of ankle arthrodesis, postoperative complications, and patient satisfaction. Methodology This was a descriptive cross-sectional study that took place at Future Hospital in Khartoum, Sudan, from July 2015 to July 2022. Our institute performed 102 ankle fusion surgeries; 14 patients were excluded from the study because they did not show up for their follow-up visit, meaning 88 candidates were included. Two cannulated screws (6.5 mm) were used for ankle fixation in all patients. The outcome was assessed two years after surgery. The American Orthopaedic Foot and Ankle Society (AOFAS) score was used to assess ankle function before surgery and two years after the procedure. Postoperative complications and patient satisfaction were reported. The primary researcher collected data through direct interviews. Result The mean age of the study participants was 52.2 years, with 36.4% being between 40 and 50 years of age. The study consisted of 43 women and 45 men. The male-to-female ratio was almost 1:1. In 56.8% of candidates, the right ankle was involved. The overall rate of complications was 11.4%. Concerning patient satisfaction, 75% of the patients were fully satisfied. Moreover, significant correlations were found between the mean postoperative AOFAS score and age group, diabetes mellitus, complications, and patient satisfaction. Conclusion Ankle arthrodesis was demonstrated to be an excellent surgical method for reducing pain and enhancing ankle joint function. The most frequent complications were delayed wound healing, infection, and non-union. The functional outcome and patient satisfaction of this procedure were statistically high; patients with a higher functional score had higher levels of satisfaction. In contrast, diabetic and elderly patients had higher rates of complications.

Abstract
Regarding the treatment of ankle arthritis, the choice of arthroscopic ankle arthrodesis (AAA) or open ankle arthrodesis (OAA) remains controversial. To guide clinical decision-making, we conducted a meta-analysis on the optimal treatment of ankle arthrodesis. We identified eligible studies published from June 1, 1969 to June 1, 2020 using the Cochrane Library, PubMed, OVID, Embase, and Medline searched the references of relevant studies. Randomized and non-randomized studies that compared outcomes of AAA and OAA were included. After the methodologic assessment, available data were extracted and statistically reviewed. The primary outcomes were overall complications rate, tourniquet time, length of the hospital stay, non-union rate, and rate to fusion. The secondary outcomes were delayed union and postoperative infection rate. We included 9 studies comparing arthroscopic and open in patients with ankle arthrodesis, comprising 467 participants. AAA had the advantage of demonstrating a lower overall complication rate (odds ratio [OR], 0.44 [95% confidence interval [CI], 0.26-0.73]; p = .002), shorter intraoperative tourniquet time (mean difference [MD], -16.49 [95% CI, -23.51 to -9.46]; p < .001), shorter length of the hospital stay (MD -1.75, 95% CI -1.94 to -1.2, p < .001),lower non-union rate (OR, -0.07 [95% CI, -0.13 to -0.02]; p <.01) and higher rate to fusion (OR, 4.2 [95% CI, 1.96-8.99]; p < .001) in comparison with OAA. Yet, no significant differences were found in delayed union (OR, 0.46 [95% CI, 0.10-2.04]; p = .30) and postoperative infection rate (OR, 0.45 [95% CI, 0.17-1.15]; p = .09) between the groups. Our results suggest that arthroscopic ankle arthrodesis is superior to open ankle arthrodesis alone in the treatment of ankle arthritis based on the overall complication rate, intraoperative tourniquet time, length of the hospital stay, non-union rate and rate to fusion. However, further high-quality randomized controlled trials with appropriate blinding methods are needed to confirm the findings.

Irritation from metalwork after ankle arthrodesis fixed using screws: a proportional meta-analysis and systematic review. Arch Orthop Trauma Surg 2023:10.1007/s00402-023-04813-1. [PMID: 36795152 PMCID: PMC10374802 DOI: 10.1007/s00402-023-04813-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 02/05/2023] [Indexed: 02/17/2023]
Abstract
OBJECTIVE Ankle arthrodesis (AA) is often fixed using cannulated screws. The irritation from metalwork is a relatively common complication, but there is no consensus regarding the need to remove the screws on a systematic basis. The aim of this study was to determine (1) the proportion of screws removed after AA and (2) whether predictors of screw removal could be identified. METHODS This PRISMA-compliant systematic review was part of a larger previous protocol registered on the PROSPERO platform. Multiple databases were searched including studies in which patients undergone AA using screws as exclusive fixation method were followed. Data were harvested regarding the cohort, the study design, the surgical technique, the nonunion and complication rate at the longest follow-up. Risk of bias was assessed using the modified Coleman Methodology Score (mCMS). RESULTS Forty-four series of patients from thirty-eight studies (1990 ankles, 1934 patients) were selected. The average follow-up was 40.8 months (range 12-110). In all studies, hardware was removed due to symptoms reported by patients and related to the screws. The pooled proportion of removal of metalwork was 3% (95% CI 2-4). The pooled proportion of fusion was 96% (95%CI 95-98), while the pooled proportion of complications and reoperations (excluding the removal of metalwork) stood at 15% (95% CI 11-18) and 3% (95% CI 2-4), respectively. The mean mCMS (50.8 ± 8.1, range 35-66) revealed only an overall fair quality of studies. The univariate analysis and the multivariate model showed that the year of publication (R = - 0.004; p = 0.01) and the number of screws (R = 0.08; p = 0.01) were associated with the screw removal rate. Specifically, we found that over time the removal rate decreased by 0.4% per year and that the use of three screws instead of two reduced the risk of removal of metalwork by 8%. CONCLUSIONS In this review, removal of metalwork after ankle arthrodesis using cannulated screws was needed in 3% of cases at an average follow-up of 40.8 months. It was indicated only in case of symptoms related to soft tissue irritation from screws. The use of three screws was paradoxically related to a reduced risk of removal of screws as compared to two-screw constructs. LEVEL OF EVIDENCE Level IV, systematic review of Level IV.

Abstract
Ankle osteoarthritis (OA) is much less frequent than knee or hip OA, but it can be equally disabling, greatly affecting the quality of life of the patients. Approximately 80% of ankle OA is post-traumatic, mainly secondary to malleolar fractures, being another of the main causes untreated in chronic instability. The average age of the patient affected by ankle OA is around 50 years, being therefore active patients and in working age who seek to maintain mobility and remain active. The authors conducted a comprehensive review of the conservative, medical, and surgical treatment of ankle OA. Initial conservative treatment is effective and should be attempted in any stage of OA. From a pharmacological point of view, non-steroidal anti-inflammatory drugs (NSAIDs) and intra-articular infiltrations can produce temporary relief of symptoms. After the failure of conservative-medical treatment, two large groups of surgical treatment have been described: joint-preserving and joint-sacrificing procedures. In the early stages, only periarticular osteotomies have enough evidence to recommend in ankle OA with malalignment. Both ankle arthrodesis and ankle replacement can produce satisfactory functional results if correctly indicated in the final stages of the disease. Finally, the authors propose a global treatment algorithm that can aid in the decision-making process.

Abstract
ABSTRACT We present a case series with the objective of identifying risk factors for nonunion after open and arthroscopic primary ankle arthrodesis. Eighty-seven patients who underwent primary ankle arthrodesis and met inclusion criteria were divided into open (N = 46) and arthroscopic (N = 41) groups. Patient and operative characteristics were retrospectively analyzed as possible risk factors for nonunion within each technique. The nonunion rate was 11% in the open and 12% in the arthroscopic group. Obesity, smoking, and ASA class 3 were highly prevalent in both groups. In the arthroscopic group, a remote history of infection and the use of headed screws had notably higher risk of nonunion, though not statistically significant. In the open group, use of bone graft trended toward lower risk of nonunion, though also not statistically significant. The results of this study demonstrated, nonunion rates are comparable between open and arthroscopic ankle arthrodesis in high-risk patients. For patients with a remote history of infection, open ankle arthrodesis may be preferable, and bone graft importance may vary with open versus arthroscopic technique. LEVEL OF EVIDENCE III.

Abstract
A wide variation of surgical options, complications, and union rates are reported in the treatment of end-stage ankle arthritis. However, open ankle arthrodesis remains the golden standard for ankle arthritis. The purpose of this study was to evaluate the union rate and complication rate as well as identify potential risk factors for different methods of fixation in patients with end-stage ankle arthritis of different etiology. In total, 42 ankles of 41 patients with ankle osteoarthritis were included for this single-center retrospective study. The mean age was 50 years (range 22-75 years). Twenty patients were treated with screw-fixation, 14 with plate(s) and 8 with intramedullary nail. The results of this study showed an overall union rate of 97.6% (41 of the 42 operated ankles) and an overall complication rate of 21.4% (9 events). The mean follow-up time was 16 months (range 2.5-83.0 months). Complications consisted of 1 nonunion, 4 deep infections, 2 cases of wound dehiscence, 1 delayed union and 1 malalignment of the ankle joint. The plate-fixation group demonstrated significantly higher infections when compared with screw and intramedullary nail fixation (p = .017). There were no other significant variables for incidence of complications between patients in the uncomplicated and complicated group. This study achieved good clinical results for different methods of fixation in open ankle arthrodesis. In specific, the use of intramedullary nail provides excellent results for end-stage ankle arthritis with high union rate and a low complication rate.

Abstract
BACKGROUND The purpose of the present study was to evaluate the efficacy of biological adjuvants in patients managed with hindfoot arthrodesis. METHODS A systematic review of the PubMed and Embase databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with use of specific search terms and eligibility criteria. Assessment of evidence was threefold: level of evidence by criteria as described in The Journal of Bone & Joint Surgery, quality of evidence according to the Newcastle-Ottawa scale, and conflicts of interest. Meta-analysis was performed with fixed-effects models for studies of low heterogeneity (I2 < 25%) and with random-effects models for studies of moderate to high heterogeneity (I2 ≥ 25%). RESULTS A total of 1,579 hindfeet were recruited across all studies, and 1,527 hindfeet were recorded as having completed treatment and follow-up visits. The duration of follow-up ranged from 2.8 to 43 months. Twelve of the 17 included studies comprised patients with comorbidities associated with reduced healing capacity. Based on the random-effects model for nonunion rates for autograft versus allograft, the risk ratio was 0.82 (95% CI, 0.13 to 5.21; I2 = 56%; p = 0.83) in favor of lower nonunion rates for autograft. Based on the random-effects model for rhPDGF/β-TCP versus autograft, the risk ratio was 0.90 (95% CI, 0.74 to 1.10; I2 = 59%; p = 0.30) in favor of lower nonunion rates for rhPDGF/β-TCP. CONCLUSIONS There is a lack of data to support the meaningful use of biological adjuvants as compared with autograft/allograft for hindfoot arthrodesis. The meta-analysis favored the use of autograft when compared with allograft but favored rhPDGF/β-TCP when compared with autograft in the short term. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
There is currently no consensus on the importance of bone graft use in ankle arthrodesis. Despite this, bone graft is widely used. We aimed to summarize the available literature on primary open ankle arthrodesis fixated with cannulated screws in order to assess the importance of bone graft in achieving more favorable rates of fusion. PubMed and Embase were queried for articles reporting on primary open ankle arthrodesis fixated with cannulated screws which specified use or non-use of bone graft. Pooled data analysis was performed. Modified Coleman Methodology Scores were calculated to assess reporting quality. Twenty-seven studies met our inclusion criteria and were divided into three groups: no bone graft (NBG), fibular onlay with bone graft (FOBG), and use of bone graft (BG). All three groups had comparable fusion rates of 94.7%, 95.3%, and 95.1% respectively (p = .98). Number needed to treat was 7 and Absolute Risk Reduction was 14.8%. The reviewed literature was largely of moderate quality, with an overall Coleman score of 60.6 and no significance between the 3 groups (p = .93). In conclusion, primary open ankle arthrodesis fixated with cannulated screws generally had favorable fusion rates, and bone graft use did not have a significant effect on union rates. The available literature suggests that bone graft may not be needed in routine tibiotalar arthrodesis in low-risk patients. It may more significantly impact patients who are at high-risk of fusion failure, and dedicated research on this high-risk subset of patients is required.

Abstract
BACKGROUND Arthrodesis is considered the gold standard for end-stage ankle arthritis in patients who fail conservative management. Achieving union is paramount while minimizing complications. An essential item for successful union is preparation of the articular surface. Our study aims to evaluate the difference in joint preparation between direct lateral and dual mini-open approaches. MATERIALS AND METHODS Ten below knee fresh-frozen specimens were used for this study. Five were prepared through lateral approach, and five using dual mini-incisions. After preparation, all ankles were dissected and images of tibial plafond and talar articular surfaces were taken. Surface areas of articulating facets and unprepared cartilage of talus, distal tibia, and distal fibula were measured and analyzed. RESULTS A greater amount of total surface area was prepared with the mini-open approach in comparison to the transfibular approach. Percentage of prepared surface area of total articulating surface (including talus and tibia/fibula), talus, tibia, and fibula with the transfibular approach were 76.9%, 77.7%, and 75%, respectively. Percentages were 90.9%, 92.9%, and 88.6% with the mini-open approach. When excluding medial gutter, there was no significant difference between techniques (83.94% vs. 90.85%, p = 0.1412). CONCLUSION Joint preparation with the mini-open approach is equally efficacious as the transfibular approach for the tibiotalar joint. The mini-open approach does provide superior preparation of the medial gutter and inferior tibial surface which may help to increase union rates and decreased complications. LEVEL OF EVIDENCE V.

Abstract
BACKGROUND Open ankle arthrodesis (OAA) remains the most widely used operation in end-stage ankle osteoarthritis. However, there is a large variation in terms of approach and fixation methods. The aim of this systematic review was to assess the effect of different approaches and fixation methods on the union rate, complication rate and functional outcome in OAA. METHODS A search of the online databases PubMed, Embase, and Cochrane library was performed to identify patients who underwent OAA with screw- and/or plate-fixation. RESULTS We identified 38 studies, including 1250 patients (1290 ankles). The union rate was 98% (95% CI 0.95-0.99) for the anterior, 96% (95% CI 0.92-0.98) for the lateral and 96% (95% CI 0.68-1.00) for the combined medial/lateral approach. Screw-fixation achieved an overall union rate of 96% (95% CI 0.93-0.98) and plate-fixation 99% (95% CI 0.96-0.99). The overall complication rate was 14%, 16% and 31% for the anterior, lateral and combined medial/lateral approaches respectively. It stood at 18% for screw-fixation and 9% for plate-fixation. The infection rate was 4%, 6% and 8% for the anterior, lateral and combined approaches respectively. Screw-fixation had an infection rate of 6% and plate-fixation 3%. The postoperative AOFAS scores were 76.8, 76.5 and 67.6 for the anterior, lateral and combined approaches respectively and 74.9 for screw- compared to 78.5 for plate-fixation. These differences did not reach statistical significance. CONCLUSION This study, the first of its kind, found little difference in terms of results between approach and fixation method used in OAA.

Abstract
BACKGROUND The open anterior approach to ankle arthrodesis offers a technique that provides several advantages for surgeons, such as easier visualization of the joint for deformity correction and preservation of the malleoli for potential future conversion to total ankle arthroplasty. The purpose of this study was to evaluate clinical, radiographic, and functional outcomes in a large series of patients undergoing open ankle arthrodesis via a fibular-sparing anterior approach. METHODS A retrospective review was performed of patients undergoing primary ankle arthrodesis with a single fellowship-trained foot and ankle orthopedic surgeon between 2009 and 2017. Patients were excluded if an approach other than anterior was performed. Patient-reported outcome measures (Foot and Ankle Ability Measure-Activities of Daily Living [FAAM-ADL], Short-Form 12 [SF-12], and visual analog scale [VAS] pain) were subsequently collected at a minimum of 24 months (2 years) following index surgery, along with outcome satisfaction and likelihood to repeat surgery. Fusion of the tibiotalar joint at the time of last radiographic follow-up was also assessed. Paired t tests were performed to assess change in pre- to postoperative outcomes, while linear regression analysis was performed to identify any patient factors associated with outcomes. Eighty-one patients, including 31 women and 50 men, with a mean age of 51.5 years and a mean follow-up of 58.9 (range, 24-104) months, were included. RESULTS Sixty-two patients reported significant improvement in mean FAAM-ADL (P < .0001), SF-12 Physical Composite Scale (P < .0001), and VAS pain (P < .0001), while the SF-12 Mental Composite Scale also improved, though not significantly (P = .2854). Twelve patients (14.8%) experienced complications following their arthrodesis procedure. Seventy-nine patients (97.5%) achieved fusion at their last radiographic follow-up. Multiple linear regression analysis revealed age (B = 0.071 [0.004, 0.128]; P = .0373) to have a positive association with postoperative VAS pain. CONCLUSION Ankle arthrodesis utilizing a fibular-sparing anterior approach combined with the transarticular screw fixation technique offers surgeons several advantages, along with a low postoperative complication rate, high rate of radiographic evidence of joint fusion, and substantially large improvement in pain and functional levels.

Abstract
The transfibular approach is a common procedure for tibiotalar fusion. However, this technique has several concerns: inadequate stability to resist rotational and shearing forces, a fibula is suboptimal for bone grafting, and an onlay fibular graft that might prevent impacting and cause distraction. We present a modified transfibular technique using partial fibular resection and onlay bone graft, which may address these potential problems. This study aimed to evaluate whether the ankle joint is well fused with neutral alignment and functionally improved at the final follow-up. For this study, 27 consecutive patients (mean age, 68.5 years; range, 58–83) who underwent tibiotalar fusion with a follow-up period of >1 year were retrospectively included. A modified transfibular lateral approach was performed, in which the distal anterior half fibula was resected and fixed as an onlay graft to achieve fusion between the tibia, fibula, talus, and fibular onlay graft simultaneously. Radiographic outcomes were assessed using computed tomography at 4 months after operation and serial follow-up radiographs. Functional outcomes were assessed using the American Orthopedic Foot and Ankle Society hindfoot scale and Foot and Ankle Outcome Score. The mean follow-up period was 17.3 (range, 12–32) months. Four months after operation, complete union was achieved in 13 patients, near-complete union in 8 patients, and partial union in the remaining 6 patients. At the final follow-up, all the patients achieved complete union and maintained neutral ankle alignment. The functional outcome showed a significant increase between the preoperative and postoperative periods. One minor complication occurred, in which medial side ankle pain was relieved after screw removal. This modified technique is safe and effective, and has several merits, including saving the soft tissue of the anterior ankle, saving the course of the peroneal tendons by leaving the posterior half of the fibula, resected fibula serving as a good bone stock, and reducing the likelihood of valgus deformity after fibulectomy.

Abstract
Background Research on outcomes after ankle fusion focuses on basic activities of daily living, fusion rates, and gait parameters. Little has been reported on the patient’s perspective after surgery. The purpose of this study was to determine the change in patient reported physical function and pain interference after ankle fusion surgery to guide patient expectations and improve provider communication. Methods This was a retrospective review of prospectively collected patient reported outcome measurement information system (PROMIS) data in 88 ankle arthrodesis procedures performed from May 2015 to March 2018. The PROMIS Physical function (PF) and pain interference (PI) measures were collected as routine care. Linear mixed models were used to assess differences at each follow-up point for PF and PI. Preoperative to last follow-up in the 120–365 day interval was assessed using analysis of variance. Outcomes included T-scores, z-scores, and PROMIS-Preference (PROPr) utility scores for PF and PI and the percentage of patients improving by at least 4 T-score points. Results The linear mixed model analysis for PF after the 120–149 days, and for PI, after 90–119 days, indicated recovery plateaued at 39–40 for PF and 57–59 for PI T-scores. The change in the PI T-score was the greatest with a mean T-score improvement of − 5.4 (95% CI − 7.7 to − 3.1). The proportion of patients improving more than 4 points was 66.2% for either PF or PI or both. The change in utility T-scores for both PF (0.06, 95% CI 0.02 to 0.11) and PI (0.15, 95% CI 0.09 to 0.20) was significantly improved, however, only PI approached clinical significance. Conclusion Average patients undergoing ankle fusion experience clinically meaningful improvement in pain more so than physical function. Average patient recovery showed progressive improvement in pain and function until the four-month postoperative time point. Traditional dogma states that recovery after an ankle fusion maximizes at a year, however based on the findings in this study, 4 months is a more accurate marker of recovery. A decline in function or an increase in pain after 4 months from surgery may help to predict nonunion and other complications after ankle arthrodesis. Level of evidence Level II, prospective single cohort study.

Abstract
AIMS Infected and deformed neuropathic feet and ankles are serious challenges for surgical management. In this study we present our experience in performing ankle arthrodesis in a closed manner, without surgical preparation of the joint surfaces by cartilaginous debridement, but instead using an Ilizarov ring fixator (IRF) for deformity correction and facilitating fusion, in arthritic neuropathic ankles with associated osteomyelitis. METHODS We retrospectively reviewed all the patients who underwent closed ankle arthrodesis (CAA) in Ilizarov Scientific Centre from 2013 to 2018 (Group A) and compared them with a similar group of patients (Group B) who underwent open ankle arthrodesis (OAA). We then divided the neuropathic patients into three arthritic subgroups: Charcot joint, Charcot-Maire-Tooth disease, and post-traumatic arthritis. All arthrodeses were performed by using an Ilizarov ring fixator. All patients were followed up clinically and radiologically for a minimum of 12 months to assess union and function. RESULTS The union rate for Group A was 81% (17/21) while it was 84.6% (33/39) for Group B. All the nonunions in Group A underwent revision with an open technique and achieved 100% union. Mean duration of IRF was 71.5 days (59 to 82) in Group A and 69 days (64.8 to 77.7) in Group B. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was similar in both groups. The postoperative hospital stay was shorter in Group A (21 days (SD 8)) than Group B (28 days (SD 9)). In the latter Group there were more problems with wound healing and greater requirement for antibiotic treatment. The mean operating time was 40 minutes (SD 9) in Group A compared to 80 minutes (SD 13) in Group B. Recurrence of infection occurred in 19% (4/21) and 15.5% (6/39) for Group A and Group B respectively. CONCLUSION We found CAA using an IRF to be an effective method for ankle arthrodesis in infected neuropathic foot and ankle cases and afforded comparable results to open methods. Due to its great advantages, Ilizarov method of CAA should always be considered for neuropathic ankles in suitable patients. Cite this article: Bone Joint J 2020;102-B(4):470-477.

Abstract
Aims Postoperative rehabilitation regimens following ankle arthrodesis vary considerably. A systematic review was conducted to determine the evidence for weightbearing recommendations following ankle arthrodesis, and to compare outcomes between different regimens. Patients and Methods MEDLINE, Web of Science, Embase, and Scopus databases were searched for studies reporting outcomes following ankle arthrodesis, in which standardized postoperative rehabilitation regimens were employed. Eligible studies were grouped according to duration of postoperative nonweightbearing: zero to one weeks (group A), two to three weeks (group B), four to five weeks (group C), or six weeks or more (group D). Outcome data were pooled and compared between groups. Outcomes analyzed included union rates, time to union, clinical scores, and complication rates. Results A total of 60 studies (2426 ankles) were included. Mean union rates for groups A to D were 93.2%, 95.5%, 93.0%, and 93.0%, respectively. Mean time to union was 10.4 weeks, 14.5 weeks, 12.4 weeks, and 14.4 weeks for groups A to D, respectively. Mean complication rates were 22.3%, 23.0%, 27.1%, and 28.7% for groups A to D, respectively. Reporting of outcome scores was insufficient to conduct meaningful analysis. Conclusion Outcomes following ankle arthrodesis appear to be similar regardless of the duration of postoperative nonweightbearing, although the existing literature is insufficient to make definitive conclusions.

Abstract
There are several reconstructive procedures in foot and ankle surgery wherein structural grafts are needed to fill defects, restore height, and maintain correction while providing an osteoconductive environment until fusion occurs. Traditionally used autografts and allografts have their disadvantages and limitations. Porous tantalum, with stiffness similar to bone and its biocompatibility, can be a viable option in foot and ankle reconstructive procedures.

Abstract
BACKGROUND The aims of this study were to establish the likelihood of additional surgery after ankle fusion, determine the interval for developing osteoarthrosis in the ipsilateral subtalar or Chopart joints, and evaluate its clinical relevance. MATERIAL AND METHODS A retrospective clinical and radiological study with a minimum follow-up of 24 months was performed. Short-Form 36 Heath Survey, Foot Function Index, American Orthopaedic Foot and Ankle Society Score (AOFAS) and a visual analog scale (VAS) were used to evaluate pain level and quality of life in at least 62 adult patients. RESULTS A total of 57% of our patients developed osteoarthrosis in at least one of the related joints and 28% of them required additional surgery due to pain. Patients who received workers' compensation had significantly lower AOFAS and higher VAS pain values. CONCLUSION More than half of the study cohort developed osteoarthrosis in the related joints after ankle fusion, but fewer than one-third required further joint fusion surgery as a consequence.

Abstract
BACKGROUND Arthrodesis is an effective and reliable treatment for end-stage ankle arthritis; however, many patients develop ipsilateral adjacent joint arthritis following surgery. The mechanism that drives adjacent joint arthritis remains uncertain. Cadaveric simulation permits direct investigation of the effects of both arthrodesis and movement strategy on adjacent joints during simulated walking. The objective of this study was to identify the isolated effect of ankle arthrodesis on adjacent joint kinematics during simulated walking. METHODS Effects of ankle arthrodesis on adjacent joint kinematics were assessed in 8 cadaveric foot and ankle specimens using a robotic gait simulator. Gait parameters acquired from healthy adults and patients with ankle arthrodesis were used as inputs for simulations. Three-dimensional subtalar and talonavicular joint kinematics were directly measured before and after ankle arthrodesis, and healthy- and arthrodesis-gait parameters were applied to identify the isolated effect of the ankle arthrodesis on adjacent joint kinematics. RESULTS Ankle arthrodesis increased subtalar and talonavicular joint motion during early and midstance independent of which gait parameters were used as inputs to the gait simulator. However, adjacent joint motions did not differ between the control and arthrodesis condition during late stance, when the healthy gait parameters were used as inputs. Conversely, adjacent joint motion decreased during late stance following arthrodesis when simulating gait using parameters typical in arthrodesis patients. CONCLUSIONS Regardless of the gait parameter inputs, subtalar and talonavicular joint motions increased from normal kinematics, which likely increase the biomechanical burden placed on these adjacent joints and may lead to joint degeneration. CLINICAL RELEVANCE Increased motion of the adjacent joints caused by ankle arthrodesis may explain the articular degeneration observed clinically.

Abstract
BACKGROUND Ankle arthrodesis provides satisfactory functional outcome based on basic daily activities, but information regarding more demanding tasks is limited. Also, studies reporting longer term survival and complication rates are sparse and concern small study populations. This study reports functional outcome with more focus on demanding tasks and sports and reports the mid- to long-term union and complication rates in a large study population. METHODS Between 2005 and 2010, an ankle arthrodesis was performed on 185 ankles. Clinical results were retrospectively assessed with the Foot Function Index (FFI), visual analog scale (VAS) for pain, and the Foot and Ankle Ability Measure (FAAM). Information regarding sports pre- and postoperatively was obtained through a questionnaire. In addition, postoperative complications, reoperations, and failures (defined as nonunion of the ankle arthrodesis) were determined. Mean follow-up time was 8 years. RESULTS FFI scores significantly improved, the FAAM ADL score was 70%, and the mean VAS for pain at the ankle/hindfoot at follow-up was 20. Sports participation slightly diminished from 79.5% prior to the onset of disabling complaints to 68.9% postoperatively. Of the patients, 73.1% were able to hike with a median hiking time of 40 minutes (range, 2-600 minutes). Kneeling could be performed on average 10 minutes (range, 2-60 minutes) in 39.8% and jumping down from steps by 23.5% of the patients. A small selection of patients was able to sprint (14%), and 16.8% of the patients were able to run a median distance of 60 meters (range, 3-1000 meters). Failure occurred in 9.2% and other postoperative complications were present in 21.6%, requiring reoperation in 8.6% of the cases. CONCLUSION Ankle arthrodesis led to satisfactory functional outcome and pain reduction. Most patients remained active in sports, but a transition to less demanding sporting activities was seen. The complication and failure rates were similar with previous literature, and the incidence of nonrevision secondary surgery was relatively low. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
BACKGROUND As orthopedic surgeons become skilled in ankle arthroscopy technique and evidence -based data is supporting its use, arthroscopic ankle arthrodesis (AAA) will likely continue to increase, but stabilization methods have not been described clearly. We present a technique for two parallel 7.3-mm headless compression screws fixation (HCSs) for AAA in cases of ankle arthritis with different etiology, both traumatic and non-traumatic, including neuromuscular and inflammatory patients. MATERIALS AND METHODS We retrospectively verified 24 consecutive patients (25 ankles) who underwent AAA between 2011 and 2015. The average follow-up was 26 months (range 18 to 52 months). Arthrodesis was performed in 16 patients due to posttraumatic arthritis (in 5 as a sequela of pilon, 6 ankles, 3 tibia fractures, and 2 had arthritis due to chronic instability after lateral ligament injury), in 4 patients due to neuromuscular ankle joint deformities, and in 4 patients due to rheumatoid arthritis. RESULTS Fusion occurred in 23 joints (92%) over an average of 12 weeks (range 6 to 18 weeks). Ankle arthrodesis was not achieved in 2 joints (8%), both in post-pilon fracture patients. The correct foot alignment was not achieved in 4 feet (16%). None of the treated patients required hardware removal. CONCLUSION The presented technique was effective in achieving a high fusion rate in a variety of diseases, decreasing intra- and post-operative hardware complications while maintaining adequate bone stability.

Abstract
Ankle arthrodesis is a common treatment used for patients with end-stage ankle arthritis (ESAA). The surgical goal of ankle arthrodesis is to obtain bony union between the tibia and talus with adequate alignment [slight valgus (0°-5°)], neutral dorsiflexion, and slight external rotation positions) in order to provide a pain-free plantigrade foot for weightbearing activities. There are many variations in operative technique including deferring approaches (open or arthroscopic) and differing fixation methods (internal or external fixation). Each technique has its advantage and disadvantages. Success of ankle arthrodesis can be dependent on several factors, including patient selection, surgeons' skills, patient comorbidities, operative care, etc. However, from our experience, the majority of ESAA patients obtain successful clinical outcomes. This review aims to outline the indications and goals of arthrodesis for treatment of ESAA and discuss both open and arthroscopic ankle arthrodesis. A systematic step by step operative technique guide is presented for both the arthroscopic and open approaches including a postoperative protocol. We review the current evidence supporting each approach. The review finishes with a report of the most recent evidence of outcomes after both approaches and concerns regarding the development of hindfoot arthritis.

Abstract
Arthroscopic and open ankle arthrodesis have been compared in very few studies, and no consensus has been reached regarding the incidence of postoperative revision surgery associated with each technique. The purpose of the present study was to compare these 2 approaches for the incidence of postsurgical operations. Patients who had undergone either arthroscopic or open ankle arthrodesis were identified between January 2005 to December 2011 in the PearlDiver(™) database using a predetermined algorithm and searched for the following postsurgical operations: revision ankle arthrodesis, midfoot arthrodesis, and hindfoot arthrodesis. In the current database, 7322 cases were performed with an open technique and 1152 arthroscopically. The incidence of revision arthrodesis was not significantly different statistically between the 2 techniques. However, the incidence of subsequent adjacent joint arthrodesis was greater for the open cohort (5.6% versus 2.6%; odds ratio 2.17, 95% confidence interval 1.49 to 3.16). In the open cohort, the incidence of hindfoot arthrodesis was greater than the incidence of midfoot arthrodesis (3.9% versus 1.6%, odds ratio 2.43, 95% confidence interval 1.95 to 3.01). The results showed that although open ankle arthrodesis is more commonly performed, it is associated with a greater incidence of subsequent adjacent joint arthrodesis specifically in the hindfoot.

Abstract
PURPOSE To review the outcome of 23 ankle arthrodeses using burring, curettage, multiple drilling, and fixation with 2 retrograde screws through a single lateral incision. METHODS Records of 22 consecutive patients aged 39 to 79 (mean, 62.4) years who underwent 23 ankle arthrodeses for end-stage ankle arthritis were reviewed. Through a single lateral incision, articular cartilage was removed using burring and curettage, and multiple holes were drilled using a Kirschner wire, followed by fixation with 2 retrograde screws. The resected distal fibula was fixed to the distal part of the talus and tibia. The position of the ankle and subtalar joint arthrosis was assessed by 2 orthopaedic specialists. Pre- and post-operative American Orthopaedic Foot and Ankle Society (AOFAS) scores were evaluated. RESULTS The mean operating time was 122 minutes. The mean follow-up period was 41 months. The mean postoperative ankle alignment was suboptimal: 2.7º varus, 6.7º plantar flexion, and 2.9º internal rotation. The mean AOFAS score improved from 30 to 71 (p<0.01). The postoperative varus ankle alignment was not associated with the AOFAS score (r= -0.13, p=0.569). Of the 23 cases, one was nonunion and 22 achieved bone union after a mean of 5.4 (range, 2-16) months; 3 of them were delayed union. Despite bone union, 7 patients complained of persistent pain; 4 of them had progressive arthrosis of the adjacent subtalar joints (n=2) or subtalar and talonavicular joints (n=2). CONCLUSION Ankle arthrodesis using burring, curettage, multiple drilling, and fixation with 2 retrograde screws achieved a high union rate and acceptable functional score without serious complications.

Abstract
BACKGROUND While autogenous cancellous iliac crest bone graft is the gold standard for foot and ankle surgery, it lacks Level I evidence. Although one third of all graft cases performed in the United States today rely on allograft, some surgeons believe no graft is necessary. We hypothesized that a systematic review of the foot and ankle literature would reveal that (1) autogenous bone graft during foot and ankle arthrodesis would demonstrate healing rates that were superior to the use of either using allograft or no bone graft at all, and (2) these differences would be even more dramatic in patients having risk factors that impair bone healing. To our knowledge, neither of these assessments to date has ever been performed with this body of literature. The goal of this study was to review the use and union rates of bone graft during foot and ankle arthrodesis and determine if autogenous bone graft was superior. METHODS A literature search was performed to include articles between 1959 and 2012 using autograft, allograft, and/or no bone graft for foot and/or ankle arthrodesis. Case reports involving fewer than four patients, investigations failing to incorporate outcome data, those involving orthobiologic augmentation, and those including vascularized graft, xenograft, or pediatric patients were excluded. Recorded search results included patient demographics, comorbidities, pre-operative diagnosis, surgical procedure, bone graft type and indication, union rate, method of fixation, patient satisfaction, all outcome scores, definition of healing/success, and any listed complications including revision. Final data were stratified based upon the type of graft material. RESULTS This search generated 953 related articles, of which 159 studies (5327 patients) met inclusion criteria. The majority (153/159) were retrospective case series. Systematic review demonstrated a trend toward higher union rates for cancellous autograft (OR 1.39, p=0.11), structural autograft (OR 1.52, p=0.09), and cancellous allograft (OR 1.31, p=0.52) relative to no graft material, but none reached statistical significance. Compared to no graft, structural allograft trended toward worse performance (OR 0.62, p=0.17). The overall probability of union was 93.7% for cancellous autograft, 94.2% for structural autograft, 93.3% for cancellous allograft, 91.4% for no graft, and 86.9% for structural allograft. When only comparing the 19 papers that included a no graft arm (91.9% union rate), data revealed the highest union using cancellous autograft (95.1%, OR 1.73, p=0.09) and structural autograft (96.3%, OR 2.33, p=0.06) while only 76% for structural allograft. No significant statistical association existed between union rates and other recorded variables. CONCLUSION Systematic analysis of bone graft use in foot and ankle fusions favors the use of autograft and cancellous allograft for optimized healing rates, although no differences were statistically significant. If we assume that graft material been chosen for more complex procedures having lower anticipated union rates, then these data lend further support to the use of autograft and cancellous allograft.

Abstract
Ankle osteoarthritis is less common than hip or knee osteoarthritis; however, it is a relatively common presentation and is predominantly related to previous trauma. Treatments have traditionally consisted of temporizing measures such as analgesia, physiotherapy, and injections until operative treatment in the form of arthrodesis is required. More recently, interest has been increasing in both nonoperative and alternative operative options, including joint-sparing surgery, minimal access arthrodesis, and new arthroplasty designs. The present systematic instructional review has summarized the current evidence for the treatment options available for ankle osteoarthritis.

Abstract
The purpose of the present study was to compare the primary bending stiffness characteristics of 5 different ankle arthrodesis fixation techniques: 3 compression screws, an anterior locking plate, a lateral locking plate, an anterior locking plate with a compression screw, and a lateral locking plate with a compression screw. A total of 25 full-scale anatomic models consisting of fourth-generation composite tibiae and tali were tested using an Instron 4505 Universal Testing System. We hypothesized that the use of a compression screw with a locking plate would add considerable stiffness to the fixation construct compared with the use of a locking plate alone. The data have shown that an anterior or lateral plate with a compression screw provides significantly greater stiffness than both a plate and 3 compression screws used individually. No significant difference was seen between the anterior plate with a compression screw and the lateral plate with a compression screw. No significant differences were found among the use of an anterior plate, a lateral plate, or 3 compression screws. We have concluded that when using a locking plate in an anterior or lateral configuration, the addition of a compression screw will considerably increase the primary bending stiffness of ankle arthrodesis.

Abstract
BACKGROUND Ankle arthrodesis is commonly used for the treatment of osteoarthritis or failed arthroplasty. Screw fixation is the predominant technique to perform ankle arthrodesis. Due to a considerable frequency of failures research suggests the use of an anatomically shaped anterior double plate system as a reliable method for isolated tibiotalar arthrodesis. The purpose of the present biomechanical study was to compare two groups of ankle fusion constructs - three screw fixation and an anterior double plate system - in terms of primary stability and stiffness. METHODS Six matched-pairs human cadaveric lower legs (Thiel fixated) were used in this study. One specimen from each pair was randomly assigned to be stabilized with the anterior double plate system and the other with the three-screw technique. The different arthrodesis methods were tested by dorsiflexing the foot until failure of the system, defined as rotation of the talus relative to the tibia in the sagittal plane. Experiments were performed on a universal materials testing machine. The force required to make arthrodesis fail was documented. For calculation of the stiffness, a linear regression was fitted to the force-displacement curve in the linear portion of the curve and its slope taken as the stiffness. RESULTS For the anatomically shaped double-plate system a mean load of 967N was needed (range from 570N to 1400N) to make arthrodesis fail. The three-screw fixation method resisted a mean load of 190N (range from 100N to 280N) (p=0.005). In terms of stiffness a mean of 56N/mm (range from 35N/mm to 79N/mm) was achieved for the anatomically shaped double-plate system whereas a mean of 10N/mm (range from 6N/mm to 18N/mm) was achieved for the three-screw fixation method (p=0.004). CONCLUSIONS Our biomechanical data demonstrates that the anterior double-plate system is significantly superior to the three-screw fixation technique for ankle arthrodesis in terms of primary stability and stiffness.

Abstract
Double fusion (i.e., fusion of the subtalar and talonavicular joint) represents a modification of triple arthrodesis preserving integrity of the calcaneocuboidal joint. Our aims were (1) to evaluate dynamic plantar pressure distribution in patients undergoing double arthrodesis, (2) to obtain a comparison of kinematic changes to healthy feet, (3) to evaluate the influence of radiographic alignment, and (4) to assess functional outcome. Sixteen feet (14 patients) treated by double fusion due to fixed planovalgus deformity were included. Dynamic plantar pressure distribution was assessed using a capacitive pressure platform. Results were compared with a demographically matched control group. Clinical assessment included the American Orthopaedic Foot and Ankle Society (AOFAS) score and radiographic assessment included measurement of talometatarsal, calcaneal pitch, and talocalcaneal (TC) angle on lateral radiographs. Significant differences in plantar pressure distribution were found for maximum force of the hindfoot, midfoot, and big toe region: While the hindfoot and hallux represented decreased load in the double arthrodesis patients, load increased in the midfoot region compared with healthy controls. The lateral talus-first metatarsal-angle increased from -16.3° to -8.2°, and the TC angle decreased from 41.3° to 35.8° (p < 0.05). The pre- and post-operative AOFAS score increased from 37 points (SD, 16.3) to 70 points (SD, 16.7). These results revealed that double arthrodesis represents a reliable method for correction of planovalgus deformity. Compared with healthy feet, force transmission of the midfoot is increased whereas push-off force decreases.

Abstract
BACKGROUND In open ankle arthrodesis, debate remains as to which surgical approach and fixation devices should be used. The purpose of this study was to identify union, complication, and patient satisfaction rates of ankle fusions performed at our institution, using the plane between extensor hallucis longus and tibialis anterior with medial tibiotalar screw internal fixation. MATERIALS AND METHODS A retrospective review was performed of all isolated primary fusions between 2005 and 2009. Eighty-two ankles were identified in 73 patients. All patient records were reviewed, and 57 patients (65 ankles) attended for clinical evaluation and scoring. Age range at surgery was 18 to 75 years (mean, 56.1 years); 8 patients were smokers. Diagnoses were trauma in 52 patients (63%), osteoarthritis in 17, rheumatoid arthritis in 7, Charcot-Marie-Tooth disease in 3, congenital talipes equinovarus in 2, and talar avascular necrosis in 1. Follow-up range was 7 months to 8.3 years (mean, 4 years). RESULTS Time to union ranged from 8 to 39 weeks (mean, 13.3) with a union rate of 100%. The AOFAS range was 12 to 93 (mean, 70). Eighty percent were "very satisfied" or "satisfied." Major complication rate was 14.6%: 7 malalignments; 3 wound problems; 2 complex regional pain syndrome; and 2 delayed unions, both smokers. CONCLUSIONS An excellent union rate, high patient satisfaction, and low complication rate were achieved with this technique. Varus malalignment and persistent pain resulted in dissatisfaction. Many patients remained highly active, and bilaterally fused patients functioned as well as unilateral ones. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
OBJECTIVES Tibiotalar (TT) arthrodesis is still a very important option in the treatment of primary or post-traumatic arthritis of the ankle but persists the controversy regarding the optimal method for the fixation of the arthrodesis site. No matter the implant used, the goal is to obtain a solid, healthy, pain-free fusion. The purpose of the current study is to present the preliminary results of a novel laterally based tibiotalar compression arthrodesis system using a locked plate. METHODS Thirteen consecutive patients with tibiotalar arthritis were submitted to an arthrodesis using a new lateral plating system. The average age was 59.7 years (range 36~72); nine patients were male and four female. Using a cutting guide, the remaining articular surfaces of the tibia and talus were removed. A compression device was applied to avoid malalignment of the ankle and a precontoured lateral locking plate was used to achieve the joint fusion. RESULTS Both the AOFAS ankle-hindfoot score and the VAS score improved with the surgery. All patients' ankles fused by 6 months. In all patients we found a very good alignment in the sagittal, coronal and transverse planes. CONCLUSION We believe that a combination of a bilateral compression, contoured bony cuts, and lateral locked plating offers a novel, accurate and useful technique for ankle arthrodesis.

Abstract
BACKGROUND Ankle arthrodesis has been the gold standard operative treatment for ankle arthritis refractory to nonoperative treatment. Although multiple studies have evaluated the outcomes after ankle fusion, none has focused on outcomes in elderly patients. The purpose of this study was to evaluate outcomes of ankle fusion in patients over the age of 70. METHODS Thirty patients (30 ankles) over the age of 70 who underwent ankle fusion were identified. Average age at the time of surgery was 74.5 years (±3.7). The Foot and Ankle Ability Measure (FAAM) was obtained postoperatively in 22 of the 23 patients still living. Radiographs were followed until union with an average followup of 2.2 years. RESULTS Union was achieved in 27 of 30 ankles (90%). Postoperative radiographs showed 11 (36.6%) patients had progression of subtalar arthritis. The average postoperative FAAM score was 81.5 (±18.3) with an average followup of 8.5 years (±1.7). Subjectively, when asked to compare present function with their prearthritic state, the average response was 75.1% (±19.6). The average American Orthopaedic Foot and Ankle Society hindfoot score was 73.0 (±11.5). Complications included nonunion, deep infection, and adjacent joint arthritis. CONCLUSIONS In this clinical cohort, ankle fusion was found to be effective in the treatment of ankle arthritis. Functional outcome was satisfactory and the rate of union was comparable with that previously reported in the literature for younger patients. Although total ankle arthroplasty is becoming increasingly popular, ankle arthrodesis is an effective surgical treatment option in an elderly patient population.

Abstract
BACKGROUND Structural bone grafts are often used in foot and ankle surgery to fill gaps, maintain height, length or correction. Bone graft, whether autograft or allograft, has limitations and disadvantages. With porosity and mechanical properties similar to native bone, porous tantalum has been used successfully in hip and knee applications. This study investigates the potential advantages of porous tantalum as a substitute for conventional bone graft in foot and ankle surgery. METHODS A retrospective review of 27 arthrodesis procedures was performed of foot and ankle procedures using Trabecular Metal porous tantalum over a period of 5 years. Twenty-five patients were involved. Mean age at the time of surgery was 63 (range, 41 to 80) years. All the patients had pathologies in the foot and ankle that required arthrodesis with structural graft. Average followup was 27 (range, 12 to 72) months. RESULTS At final followup the mean American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot/Midfoot score improved from 40.6 (range, 16 to 64) preoperatively to 86.3 (range, 57 to 100) postoperatively (p < 0.001). When the pain component of the AOFAS was examined, the score improved from a mean of 8.2 (range, 0 to 20) to 35.2 (range, 20 to 40), (p < 0.001). At the time of last followup, 56% of patients reported no pain, 40% reported mild occasional pain, and 4% reported moderate pain. CONCLUSION Porous tantalum therefore, was found to be a viable alternative to conventional bone graft when structural support was required.

Abstract
PURPOSE Ankle arthrodesis (AAD) and total ankle replacement (TAR) are the major surgical treatment options for severe ankle arthritis. There is an ongoing discussion in the orthopaedic community whether ankle arthrodesis or ankle fusion should be the treatment of choice for end stage osteoarthritis. The purpose of this study was to compare the participation in sports and recreational activities in patients who underwent either AAD or TAR for end-stage osteoarthritis of the ankle. METHODS A total of 41 patients (21 ankle arthrodesis /20 TAR) were examined at 34.5 (SD18.0) months after surgery. At follow-up, pre- and postoperative participation in sports and recreational activities has been assessed. Activity levels were determined using the ankle activity score according to Halasi et al. and the University of California at Los Angeles (UCLA) activity scale. Clinical and functional outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score. The percentage of patients participating in sports and recreational activities, UCLA score and AOFAS score were compared between both treatment groups. RESULTS In the AAD group 86% were active in sports preoperatively and in the TAR group this number was 76%. Postoperatively in both groups 76% were active in sports (AAD, p = 0.08). The UCLA score was 7.0 (± 1.9) in the AAD group and 6.8 (± 1.8) in the TAR group (p = 0.78). The AOFAS score reached 75.6 (± 14) in the AAD group and 75.6 (± 16) in the TAR group (p = 0.97). The ankle activity score decrease was statistically significant for both groups (p = 0.047). CONCLUSIONS Our study revealed no significant difference between the groups concerning activity levels, participation in sports activities, UCLA and AOFAS score. After AAD the number of patients participating in sports decreased. However, this change was not statistically significant.

Abstract
INTRODUCTION Arthrodesis is a well-established treatment option for end-stage osteoarthritis of the ankle. Osteoarthritis of the ankle can alter plantar pressure distribution. However, surprisingly little is known about the effect of ankle arthrodesis to alter plantar pressure distribution. The purpose of this study was to determine plantar pressure distribution in a selected group of patients with unilateral arthrodesis of the ankle joint. METHODS 20 patients with an average age of 60 years who underwent isolated unilateral ankle arthrodesis using a 3-crossed screw technique by a single surgeon were included. After a mean of 25 months (range 12-75 months) post surgery plantar pressure distribution was determined in five regions of the foot. The outcome was evaluated clinically, using the American Orthopaedic Foot and Ankle Society hindfoot score, as well as radiographically. The contralateral normal foot was used as a control. FINDINGS Comparing the foot that underwent tibiotalar arthrodesis to the contralateral normal foot, differences were found in the peak pressure and maximum force in the toe region and the lateral midfoot region. In addition, a decrease in the contact time in the forefoot region and a decrease of the contact area in the toe region of the operated foot were identified. The other regions did not show a significant difference. The mean American Orthopaedic Foot and Ankle Society score of the operated leg was 79 (range 46-92) at the last follow up, and the mean fixation angle of the arthrodesis on lateral weight bearing radiographs was 90° (range 86°-100°). INTERPRETATION Our results indicate that arthrodesis of the ankle joint can provide high levels of function with minimal changes in the plantar pressure distribution.

Abstract
BACKGROUND The current study presents our experience with conversion of failed TAA to fusion. MATERIALS AND METHODS A retrospective review of all failed total ankles converted to fusion from 1999 to 2009 was performed at our institution. RESULTS Twelve total ankles were converted to isolated ankle fusions (Group I) and 12 converted to ankle-hindfoot fusions (Group II). All isolated ankle fusions were stabilized with anterior plate and screws with one nonunion. Structural bone graft was used in ten of 12. Mean outcome scores using the AOFAS-Ankle/Hindfoot score and Maryland Foot Score improved from preoperative values of 43 ± 13 and 56.7 ± 14 to 67 ± 12 and 71.2 ± 16 postoperatively, respectively (p < 0.05). All Group II ankle-hindfoot fusion patients were fixed using either anterior plate and screws, intramedullary nail, or a combination nail:plate construct. All received structural allografts. Five patients developed nonunion including four subtalar nonunions Preoperative scores on the AOFAS-AHS and MFS were 48.8 ± 14 and 58.3 ± 14. Postoperative scores were 51.2 ± 17 for the AOFAS and 64.5 ± 14 for the MFS. These changes were not statistically significant. However, the difference in nonunions was significant, p < 0.05. CONCLUSION Failed total ankles can be successfully converted to fusion using structural bone graft and internal fixation. The primary risk appears to be nonunion of the subtalar joint when ankle-hindfoot fusion is required. We believe this risk can be decreased by using a separate approach for preparation of the subtalar joint.

Abstract
UNLABELLED When evaluating the role of ankle arthrodesis in the treatment of severe ankle arthritis, postoperative infection, nonunion, and the development of arthritis at the adjacent joints are major issues when considering treatment alternatives. We evaluated the rate of complications, the functional outcome, and compensatory range of motion at the midtarsal joint at medium-term followup after ankle arthrodesis with four cancellous screws. We performed 94 ankle fusions in 92 patients; 12 patients were lost to followup and eight declined to participate, leaving 72 patients (76%) for evaluation. The minimum followup was 4.8 years (mean, 5.9; range, 4.8-7.8 years). No patient developed a deep infection; three patients developed postoperative hematoma which we operatively drained. Union occurred in 93 of the 94 patients (99%). The sagittal motion at the midtarsal joint averaged 24 degrees . Secondary arthritis of the subtalar and talonavicular joints developed during the followup period in 17% and 11%, respectively. Progression of preexisting arthritis occurred in 13 of 43 patients (30%) at the subtalar joint and five of 26 patients (19%) at the talonavicular joint. None of these patients had fusion of an adjacent joint. The average American Orthopaedic Foot and Ankle Society score increased from 36 preoperatively to 85 at followup. Ankle arthrodesis with screws provides high rates of union, reliable pain relief, and favorable functional medium-term results. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
BACKGROUND Arthrodesis is the most common procedure used to treat end-stage osteoarthritis of the ankle, particularly in patients with difficult conditions such as poor bone quality. While many techniques are available to fuse the ankle, current recommendations favor the use of internal fixation with screws and/or plates. Despite of progress, the complication rate remains a major concern. Non-union is one difficult problem especially with difficult bone conditions, particularly the loss of bone stock on the talar side. Therefore, fusion of the tibiotalar joint is often extended to the talocalcaneal joint to provide sufficient stability. To preserve the subtalar joint, an anterior double plate system for rigid fixation of isolated tibiotalar arthrodesis was developed. This is a preliminary report on the clinical and radiological outcome with this technique. MATERIALS AND METHODS Twenty-nine patients (15 men, 14 women; one ankle per patient) were treated from October 2006 to September 2007. We converted 16 ankles with osteoarthritis and difficult bone conditions, four non-united ankle arthrodeses, and nine failed total ankle replacements to an isolated tibiotalar arthrodesis using anterior double plating. If necessary, we used solid allograft to fill bony defects. Outcomes included bone union as assessed by radiographs, pain as indicated by the American Orthopaedic Foot and Ankle Society scores, and patient satisfaction. RESULTS Solid arthrodesis was achieved after an average of 12.3 (eight to 26) weeks in the 16 ankles without bone graft interposed between the tibia and talus, and 14.3 (range, 8 to 26) weeks in the 13 ankles with interpositional bone allograft. Radiographs showed that the position of arthrodesis obtained at the time of surgery did not change in any patient up to one year after surgery. The mean American Orthopaedic Foot and Ankle Society (AOFAS) Hindfoot Score increased from 37 (range, 20 to 63) preoperatively to 68 (range, 50 to 92) at the last followup. Twenty-seven patients (93%) were satisfied with their outcome and indicated they would have the operation again. No complications were noted. CONCLUSION The anterior double plating system was shown be a reliable method to achieve solid isolated tibiotalar arthrodesis, even in ankles with difficult conditions such as loss of bone stock due to failed total ankle arthroplasty.

Abstract
BACKGROUND The use of external ring fixation for ankle arthrodesis offers an alternative to internal screw fixation when bone quality is suboptimal, when complex ankle pathology is present, and as a salvage procedure for complicated cases. Additionally, it permits earlier weightbearing and postoperative adjustment of bone alignment and joint compression. This study was designed to determine whether there are differences in initial ankle joint fixation integrity between these two techniques. MATERIALS AND METHODS Ten fresh-frozen cadaveric lower extremities underwent ankle arthrodesis with a hybrid ring fixator, and the bending and torsional stiffness of each arthrodesed joint was quantified. Stiffness was calculated from angulation measured at the tibiotalar joint using electronic clinometers attached to those bones. The external fixators were then removed and ankle arthrodesis performed using 6.5-mm cannulated screws: three across the ankle joint, one fixing the fibula to the tibia, and one fixing the fibula to the talus. Stiffness testing was then repeated. RESULTS No statistically significant difference in bending stiffness, torsional stiffness, or joint rotation under torsional load was demonstrable between the two techniques. CONCLUSION The similarity in ankle fusion site stability achieved with external ring fixation and an optimized screw fixation technique under the described testing conditions indicates that, in cases in which suboptimal bone quality or complex ankle pathology preclude the use of internal fixation, an external fixator is a viable option. CLINICAL RELEVANCE Establishing that the primary stability of external ring fixation is comparable to that of screw fixation provides a basis for its use in cases in which screw fixation may be problematic.

Abstract
Many orthopaedic surgeons had abandoned the use of first and second generation total ankle arthroplasties due to unacceptably high complication and failure rates as compared to arthrodesis. Recently, there has been renewed interest in ankle joint replacement as longer term outcome studies have become available, and the FDA has approved several more designs. With the introduction of two new FDA approved implants in November 2006, options for surgeons interested in total ankle arthroplasty have greatly expanded. There continues to be much debate within the orthopaedic community as to indications, patient selection, and optimal component design. This review aims to provide orthopaedists with an overview of the currently available implants and literature.

Abstract
BACKGROUND Many operative techniques have been described for ankle arthrodesis, with varying fusion rates. In revisions, the fusion rate is lower than in primary arthrodesis. Recent reports have described good results after Ilizarov ankle arthrodesis. However, descriptions were qualitative, with none using an accepted score. We describe our experience with this technique and functional outcomes in our patients. METHODS Seventeen patients (average age 48 years) had primary or revision unilateral ankle arthrodesis using the Ilizarov technique at two centers. Diagnoses included post-traumatic arthritis and Charcot arthropathy. Three patients had talar osteonecrosis. Time in the frame averaged 15 weeks and in a cast 4 weeks. Followup averaged 6 years. Outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. RESULTS All ankles achieved solid fusion. The average AOFAS score was 65 out of 86 possible. Based on this, results were defined as excellent in three patients, good in eight, fair in four, and poor in two. Minor complications were common, all resolving with local treatment. No deep infection developed. One fusion malunited in 8 degrees of varus. CONCLUSIONS The Ilizarov external fixator has numerous advantages applicable to ankle fusion, including: stable fixation, respect for soft tissues, and the possibility of postoperative alignment 'fine-tuning'. Additionally, the ability to direct forces through or around skeletal elements allows varying of the load through the skeletal elements, allowing early weightbearing. The Ilizarov technique, with its high union rate, may be considered for any ankle arthrodesis but is especially useful in complex cases such as revisions, talar osteonecrosis, soft-tissue compromise, and infection. Early weightbearing is an added benefit.
