Woo SH. Parallel versus Angulated Screw Configuration in Subtalar Arthrodesis for Posttraumatic Arthritis. Clin Orthop Surg 2024; 16:477-484. [PMID: 38827769 PMCID: PMC11130629 DOI: 10.4055/cios23342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 01/22/2024] [Accepted: 01/26/2024] [Indexed: 06/05/2024] Open
Abstract
Background To compare radiographic union and clinical outcomes between parallel and angulated screw configurations (SCs) for patients undergoing subtalar arthrodesis due to posttraumatic subtalar arthritis (PSA) after displaced intra-articular calcaneal fractures. Methods This study retrospectively reviewed 140 consecutive PSA cases from March 2011 to November 2021 (parallel SC: group 1, n = 80; angulated SC: group 2, n = 60). Radiographic union, Foot and Ankle Outcome Score (FAOS), and visual analog scale (VAS) scores were among the outcome assessments. Six months after surgery, nonunion was confirmed based on plain radiographs, clinical evaluation, and computed tomography. Results Groups 1 and 2 included 14 (17.5%) and 3 (5.0%) nonunion cases, respectively (p = 0.035). There was no significant difference in preoperative FAOS and VAS scores between the groups. However, group 2 had significantly better clinical outcomes in 2 of the 5 FAOS domains (sports and quality of life), as well as VAS scores at 3 and 6 months postoperatively and at the final follow-up (p < 0.05). Conclusions Using the angulated SC for PSA had a lower nonunion rate and superior clinical outcomes than the parallel SC. Obtaining better radiological and clinical outcomes when using the angulated SC, rather than the parallel SC, would be advantageous.

The value of bone SPECT/CT in evaluation of foot and ankle arthrodesis and adjacent joint secondary osteoarthritis. Eur J Nucl Med Mol Imaging 2023; 51:68-80. [PMID: 37676502 DOI: 10.1007/s00259-023-06421-y] [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: 07/26/2023] [Accepted: 08/28/2023] [Indexed: 09/08/2023]
Abstract
OBJECTIVE To evaluate the value of SPECT/CT (single photon emission computed tomography/computed tomography) in foot and ankle arthrodesis and development of secondary osteoarthritis in the adjacent joints. MATERIALS AND METHODS SPECT/CT of 140 joints in the foot and ankle (34 upper ankle (UA), 28 lower ankle (LA), 27 talonavicular (TN), 12 calcaneo-cuboidal (CC), and 39 other smaller joints after arthrodesis in 72 patients were evaluated retrospectively regarding fusion grade in CT (0 = no fusion, 1 = < 50% fusion, 2 = > 50% fusion, 3 = complete fusion) and radiotracer uptake (0 = no uptake, 1 = mild uptake, 2 = moderate uptake, 3 = high uptake) on SPECT/CT. Severity of osteoarthritis (1 = mild, 2 = moderate, 3 = severe) and radiotracer uptake grade in adjacent joints was also assessed. In 54 patients, clinical information about interventions in the follow-up was available. RESULTS According to the SPECT/CT, arthrodesis was successful (grade 2 or 3 CT fusion and grade 0 or 1 uptake) in 73% (25/34) of UA joints, 71% (20/28) of LA joints, 67% (18/27) TN, 100% (12/12) CC joints, and 62% (24/39) of other smaller joints. In 12 joints, there were discrepant findings in SPECT/CT (fusion grade 2 and uptake grade 2 or 3 (n = 9); or, fusion grade 0 or 1 and uptake grade 1 (n = 3)). The fusion rate 6-12 months after arthrodesis was 42% (14/33), 59% (20/34) after 13-24 months, and 89% (65/73) after more than 24 months, respectively. Average radiotracer uptake in arthrodesis decreased with age: 6-12 months: 1.60, 12-24 months: 1.32, > 24 months: 0.38. There was a significant negative correlation between radiotracer uptake grade and CT fusion grade. Osteoarthritis was observed in 131 adjacent joints. During the post scan follow-up, additional arthrodeses were performed in 33 joints, of which 11 joints were re-arthrodesis and 22 were new arthrodeses in osteoarthritic adjacent joints. All these 11 joints with failed arthrodesis had grade 0 of CT fusion and grade 2 or 3 of radiotracer uptake. All 22 adjacent joints with osteoarthritis, which subsequently underwent arthrodesis, had grade 2 or 3 radiotracer uptake, and the primary arthrodesis joints were healed and fused in all these cases. CONCLUSION Bone SPECT/CT is a valuable hybrid imaging tool in the evaluation of foot and ankle arthrodesis and gives additional useful information about the development of secondary osteoarthritis in the adjacent joints with higher value for the assessment of secondary osteoarthritis. A practical four-type classification ('Lucerne Criteria') combining metabolic and morphologic SPECT/CT information for evaluation of arthrodesis joints has been proposed.

"In Situ" Joint Preparation Technique for First Metatarsophalangeal Arthrodesis: A Retrospective Comparative Review of 388 Cases. J Foot Ankle Surg 2023; 62:855-861. [PMID: 37220866 DOI: 10.1053/j.jfas.2023.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 04/08/2023] [Accepted: 05/13/2023] [Indexed: 05/25/2023]
Abstract
"Cup-shaped power reamers" and "flat cuts" (FC) are common joint preparation techniques in first metatarsophalangeal (MTP) joint arthrodesis. However, the third option of an "in situ" (IS) technique has rarely been studied. This study aims to compare the clinical, radiographic, and patient-reported outcomes (PROMs) of the IS technique for various MTP pathologies with other MTP joint preparation techniques. A single-center retrospective review was performed for patients who underwent primary MTP joint arthrodesis between 2015 and 2019. In total, 388 cases were included in the study. We found higher nonunion rates in the IS group (11.1% vs 4.6%, p = .016). However, the revision rates were similar between the groups (7.1% vs 6.5%, p = .809). Multivariate analysis revealed that diabetes mellitus was associated with significantly higher overall complication rates (p < .001). The FC technique was associated with transfer metatarsalgia (p = .015) and a more first ray shortening (p < .001). Visual analog scale, PROMIS-10 physical, and PROMIS-CAT physical scores significantly improved in IS and FC groups (p < .001, p = .002, p = .001, respectively). The improvement was comparable between the joint preparation techniques (p = .806). In conclusion, the IS joint preparation technique is simple and effective for first MTP joint arthrodesis. In our series, the IS technique had a higher radiographic nonunion rate that did not correlate with a higher revision rate, and otherwise similar complication profile to the FC technique while providing similar PROMs. The IS technique resulted in significantly less first ray shortening when compared to the FC technique.

Abstract
BACKGROUND Nonunion remains the most common major complication of ankle arthrodesis. Although previous studies have reported delayed union or nonunion rates, few have elaborated on the clinical course of patients experiencing delayed union. In this retrospective cohort study, we sought to understand the trajectory of patients with delayed union by determining the rate of clinical success and failure and whether the extent of fusion on computed tomography scan (CT) was associated with outcomes. METHODS Delayed union was defined as incomplete (<75%) fusion on CT between 2 and 6 months postoperatively. Thirty-six patients met the inclusion criterion: isolated tibiotalar arthrodesis with delayed union. Patient-reported outcomes were obtained including patient satisfaction with their fusion. Success was defined as patients who were not revised and reported satisfaction. Failure was defined as patients who required revision or reported being not satisfied. Fusion was assessed by measuring the percentage of osseous bridging across the joint on CT. The extent of fusion was categorized as absent (0%-24%), minimal (25%-49%), or moderate (50%-74%). RESULTS We determined the clinical outcome of 28 (78%) patients with mean follow-up of 5.6 years (range, 1.3-10.2). The majority (71%) of patients failed. On average, CT scans were obtained 4 months after attempted ankle fusion. Patients with minimal or moderate fusion were more likely to succeed clinically than those with "absent" fusion (P = .040). Of those with absent fusion, 11 of 12 (92%) failed. In patients with minimal or moderate fusion, 9 of 16 (56%) failed. CONCLUSION We found that 71% of patients with a delayed union at roughly 4 months after ankle fusion required revision or were not satisfied. Patients with less than 25% fusion on CT had an even lower rate of clinical success. These findings may help surgeons in counseling and managing patients experiencing a delayed union after ankle fusion. LEVEL OF EVIDENCE Level IV, retrospective cohort study.

Abstract
BACKGROUND The tibiotalar arthrodesis for end-stage ankle osteoarthritis is a surgical procedure that leads to a modification of the kinematics of the adjacent joints and may result in the development of secondary osteoarthritic degeneration of the subtalar joint. It has previously been observed that subtalar arthrodesis in this context shows a lower fusion rate than isolated subtalar arthrodesis. This retrospective study reports the results of subtalar joint arthrodesis with previous ipsilateral tibiotalar arthrodesis and suggests some factors that may compromise the fusion of the joint. METHODS Between September 2010 and October 2021, 15 arthrodeses of the subtalar joint with screw fixation were performed in 14 patients, with a fusion of the ipsilateral tibiotalar joint. Fourteen of 15 cases used an open sinus tarsi approach, 13 were augmented with iliac crest bone graft, and 11 had supplemental demineralized bone matrix (DBM). The outcome variables were fusion rate, time to fusion, and revision rate. Fusion was assessed by radiographs and computed tomography scan. RESULTS Twelve of the 15 subtalar arthrodeses (80%) fused at the first attempt with an average fusion time of 4.7 months. CONCLUSION In this limited retrospective case series, compared to the fusion rate of isolated subtalar arthrodesis reported in the literature, the rate of subtalar fusion in the presence of an ipsilateral tibiotalar arthrodesis was found to be lower.

Abstract
BACKGROUND Ankle, hindfoot, and midfoot arthrodesis surgeries are standard procedures performed in orthopaedics to treat pain and functional disabilities. Although fusions can effectively improve pain and quality of life, nonunions remain a significant concern for surgeons. With the increased availability of computed tomography (CT), more surgeons rely on this modality for increased accuracy in determining whether a fusion was successful. The objective of this study was to report the rates of CT-confirmed fusion following ankle, hindfoot, or midfoot arthrodesis. METHODS A systematic review was performed using EMBASE, Medline, and Cochrane central register from January 2000 to March 2020. Inclusion criteria included studies with adults (<18 years) that received 1 or multiple fusions of the ankle, hindfoot, or midfoot. At least 75% of the study cohort must have been evaluated by CT postoperatively. Basic information was collected, including journal, author, year published, and level of evidence. Other specific information was collected, including patient risk factors, fusion site, surgical technique and fixation, adjuncts, union rates, criteria for successful fusion (%), and time of CT. Once data were collected, a descriptive and comparative analysis was performed. RESULTS Included studies (26, n = 1300) had an overall CT-confirmed fusion rate of 78.7% (69.6-87.7). Individual joints had an overall fusion rate of 83.0% (73-92.9). The highest rate of union was in the talonavicular joint (TNJ). CONCLUSION These values are lower than previous studies, which found the same procedures to have greater than 90% fusion rates. With these updated figures, as confirmed by CT, surgeons will have better information for clinical decision making and when having informed consent conversations.

Abstract
BACKGROUND The most common indications for revision of first metatarsophalangeal joint (MTPJ) arthrodesis are symptomatic failures of prior arthrodesis, failed hallux valgus correction, and failed MTPJ arthroplasty implants. However, the outcomes of revision MTPJ arthrodesis have rarely been studied. The purpose of this study was to compare the clinical, radiographic, and patient-reported outcomes of revision MTPJ arthrodesis following different primary procedures. METHODS A retrospective review of revision MTPJ arthrodesis cases between January 2015 and December 2019 was performed. The radiographic results, patient-reported outcomes, and rates of complications, subsequent revisions, and nonunions, were analyzed and compared preoperatively and postoperatively. A multivariate analysis was utilized to determine risk factors for complications and reoperations. RESULTS This study yielded a total of 79 cases of revision MTPJ arthrodesis. The mean follow-up time was 365 days (SD ± 295). The overall complication rate was 40.5%, of which the overall nonunion rate was 19.0%. Seven cases (8.9%) required further revision surgery. The multivariate analysis revealed that Diabetes mellitus was associated with significantly higher overall complication rates (p = 0.016), and nonunion was associated with "in-situ" joint preparation techniques (p = 0.042). Visual Analog Scale (VAS) significantly improved postoperatively (p < 0.001); However, PROMIS-10 physical health and PROMIS-10 mental health did not change significantly during the study period. CONCLUSION Treatment of MTPJ surgery failures is a clinical challenge in orthopedic surgery. In our study, revision of first MTPJ surgery resulted in higher nonunion rates and overall complication rates compared to typical outcomes from primary MTPJ arthrodesis. Diabetes, Tobacco use, and "in-situ" joint preparation technique were found to be independent risk factors for complications and reoperations. LEVEL OF EVIDENCE III-Retrospective Cohort Study.

Abstract
BACKGROUND The Ilizarov fixator is a popular device for treating arthrodesis of the ankle joint in complex situations. However, the therapy can fail, with nonunion or partial union that might not be load stable. There is the possibility of follow-up surgery or extended wearing of the fixator. Full weight bearing with a carbon orthosis remains another treatment option, which has not yet been investigated.The aim of the study was to determine the rate of progress that can be obtained with a carbon orthosis in cases of partial union or nonunion after fixator removal. METHODS In this retrospective observational study thirty-three patients received a carbon orthosis after fixator removal due to nonunion or partial union. All patients were allowed to walk with the orthosis under full load. The consolidation rate was determined radiologically and compared with the imaging data obtained during the last follow-up. In addition to demographic data, the Foot and Ankle Ability Measure and pain using a numeric rating scale were determined. Nine patients had to be excluded due to insufficient follow-up, and finally n = 24 patients were included in the study. RESULTS The average duration of fixator use was 21 weeks (range 15-40 weeks), and the total average follow-up after removal of the fixator was 16 months (range 4- 56). For 14 (58.33%) patients, there was a further increase in consolidation with the orthosis after the fixator was removed. CONCLUSION The results show that if there is only partial union or nonunion, further consolidations can be achieved after the application of a carbon orthosis. In a difficult patient population, using an orthosis should therefore be attempted to avoid unnecessary revision operations.

Abstract
INTRODUCTION Charcot neuropathic osteoarthropathy (CN) can be complicated by osteomyelitis (OM). Surgery is a standard procedure to treat OM including debridement and interposition of antibiotic-loaded cement (ABLC) spacer. The course of CN and OM was investigated on a histopathological level. MATERIALS AND METHODS Diabetic patients (n = 15) suffering from CN and midfoot OM underwent surgical debridement and interposition of ABLC was interposed. 6 weeks later, ABLC was removed and bone samples were taken again. Histopathological Charcot Score (HCS), Histopathological Osteomyelitis Evaluation Score (HOES) and microbiological assessment were used to evaluate osteomyelitic and neuroosteoarthropathic activity at both time points. RESULTS Interposition of ABLC leads to microbiological/histopathological eradication of OM in 73%/87% of patients. CN activity-measured by HCS-could be reduced from moderate to low activity by ABLC spacer and correlated with HOES. CONCLUSIONS CN activity could be reduced by surgery. It can be suggested that neuroosteoarthropathic activity measured by HCS is triggered by OM.

Abstract
BACKGROUND Locking plates are increasingly used to achieve hindfoot fusion. The objective of this study was to compare hindfoot fusion outcomes with the PEEK H-pode™ (Biotech™) locking plate and the titanium Maxlock™ (Tornier-Wright™) locking plate. HYPOTHESIS A polyetheretherketone (PEEK) H-pode™ locking plate provides similar fusion rates to a titanium Maxlock™ locking plate for talo-navicular and calcaneo-cuboid arthrodesis. METHODS We conducted a retrospective comparative study in 39 patients (including 21 [54%] with pes planovalgus and 11 [28%] with neurological equinovarus deformities) who underwent talo-navicular and/or calcaneo-cuboid fusion, usually combined with subtalar fusion. The first 17 patients (January 2014-February 2016) were managed with Maxlock™ locking plates and the next 22 patients (March 2016-August 2018) with H-pode™ locking plates. These two cohorts of consecutive patients were comparable regarding age, sex distribution, body mass index, and comorbidities. At last follow-up more than 1year after surgery, we compared functional scores, pain intensity, and fusion assessed by radiographs and computed tomography (CT) (threshold set at 33%). RESULTS Mean follow-up was 42months (range: 34-63months) in the Maxlock™ group and 25months (range: 12-36months) in the H-pode™ group. At last follow-up, the two groups were not significantly different for the mean values of the American Orthopedic Foot & Ankle Society score, European Foot & Ankle Society score, and visual analogue scale pain score. Neither were the two groups significantly different for talo-navicular and calcaneo-cuboid fusion by CT. In the Maxlock™ group, we found non-significant trends towards a higher proportion of patients with talo-navicular nonunion (18% vs. 5% in the H-pode™ group) and weaker talo-navicular fusion in patients with pes planovalgus (60.8% vs. 82.0%, respectively). Radiographic results overestimated the fusion rates. DISCUSSION Talo-navicular and calcaneo-cuboid fusion was not significantly different with H-pode™ and Maxlock™ locking plates. CT was more accurate than standard radiography to assess fusion. These results underline the usefulness of PEEK locking plates for talo-navicular and calcaneo-cuboid fusion; moreover, the radiolucency of PEEK facilitates the interpretation of radiographs.

Abstract
Introduction The purpose of this study is to determine the rate of implant removal after partial carpal arthrodesis and to investigate factors associated with implant removal. Methods Case records of 22 dogs that underwent partial carpal arthrodesis at two private veterinary referral hospitals were reviewed. Details retrieved were body weight at time of surgery, sex, neuter status, breed, age, cause of carpal hyperextension injury, joint(s) involved in carpal hyperextension injury, laterality, type of implant, administration of post-operative antibiotics, post-operative outcome and indication for implant removal. Association between these factors and implant removal was evaluated. Results Of 22 partial carpal arthrodesis, 12 (55%) had implant removal due to persistent lameness and 9/12 (75%) returned to full and acceptable function after implant removal. Indications for implant removal were implant interference (8), infection (4), and migration (1). When comparing type of implant, there was a significant difference when observing implant removal rates (p = 0.04). All 5 dogs with pins and wires (100%) required implant removal. Of 17 dogs with a plate, 7 (41.2%) required implant removal. Implant removal was performed on average 114 days post-operative. Discussion Implant removal after partial carpal arthrodesis was frequent and was commonly indicated due to pin and wire fixation or plate implant interference. This study may impact how we prepare clients for potential post-operative complications and implant removal when recommending partial carpal arthrodesis.

Abstract
BACKGROUND This study investigated the incidence of and risk factors for nonunion in patients with posttraumatic subtalar arthrodesis (SA). METHODS We retrospectively reviewed 165 posttraumatic SA cases. Nonunion was diagnosed at 6 months after surgery based on the findings of clinical evaluations, plain radiographs, and CT scans. Patient-specific factors and surgeon-specific factors were evaluated as potential risk factors. RESULTS The overall nonunion rate was 13.3 % (22 of 165 cases). In the final multivariate logistic regression analysis, smoking (odds ratio [OR] = 3.64; 95 % confidence interval [CI] = 1.23-10.75), parallel screw configuration (OR = 5.70; 95 % CI = 1.62-20.06), and freeze dried iliac crest (OR = 9.16; 95 % CI = 2.28-36.79) were demonstrated as risk factors for nonunion of posttraumatic SA. CONCLUSION Patients with a history of smoking, parallel screw configuration fixation, and those who received freeze dried iliac crest as an interpositional graft, had a significantly higher rate of nonunion.

Abstract
BACKGROUND It remains unclear whether to perform a bone graft is necessary during posterior arthroscopic subtalar arthrodesis. The present research aimed to comparatively analyze the outcomes of arthroscopic subtalar arthrodesis through a 3-portal posterior approach with or without bone graft. METHODS A total of 93 patients with subtalar arthritis who underwent posterior arthroscopic subtalar arthrodesis were retrospectively examined. The patients were divided into two groups according to whether they received bone graft or not. The clinical outcomes were compared for analysis. RESULTS Among the 93 patients included, 53 received bone graft and 40 did not. The union rate and time to osseous fusion suggested no significant difference between the two groups. The improvement of clinical outcomes were comparable between the two groups at the final follow-up. CONCLUSIONS In the present study, bone graft could not effectively reduce the risk of nonunion and improve the outcome.

Abstract
PURPOSES Many studies have been performed that investigate consolidation after arthrodesis of foot and ankle joints. Consolidation in foot and ankle joints is best assessed by computed tomography (CT). However, no golden-standard methodology exists for radiological consolidation assessment from CT after ankle and foot arthrodesis. The aim of this review is to present an overview of the radiological methodologies for consolidation assessment, outcomes on reliability and validity and to advise which methodology should be used. METHOD Scientific databases were systematically searched. Eligible studies were studies that 1) performed foot or ankle arthrodesis, 2) mentioned radiological or CT follow-up in abstract, 3) performed postoperative CT in > 50% of patients. Two authors selected eligible studies and performed a risk of bias assessment with the COSMIN tool. RESULTS Risk of bias assessment showed that most studies (80%) were at high risk of bias due to poor methodology. The most popular method for consolidation assessment is by subjectively categorizing consolidation into consolidation groups, with a substantial reliability score. Another popular method is to calculate the fusion ratio and then apply a fusion threshold, to distinguish between fused and non-fused joints. This method had an excellent reliability score. In most studies a fusion threshold of 50% is used. However, four studies in this review showed that a 30% fusion threshold may by more valid. CONCLUSION Based on the results of this review we would advise to calculate fusion threshold and apply a 30% fusion threshold to distinguish fused from non-fused foot and ankle joints.

Abstract
BACKGROUND We aimed to compare outcomes of treatment of isolated talonavicular arthrodesis (ITNA) with screw only or screw plus plate, respectively. METHODS We retrospectively evaluated 40 consecutive cases of ITNA [two-screw fixation patients: Group 1 (23 cases); screw-plus-plate fixation patients: Group 2 (17 cases)]. Outcome measures included radiographic findings, Foot and Ankle Outcome Scores (FAOS), and visual analogue scale (VAS) scores. RESULTS Nonunion occurred more frequently in group 1 (21.7%) than in group 2 (5.9%), but there was no statistical significance (p = 0.216). Although the preoperative FAOS and VAS score showed similar results between both groups, there were significantly better clinical outcomes in two of five FAOS domains and VAS scores at 3 months postoperative and final follow-up (p < 0.05). CONCLUSION Although union rates were not significantly different, nonunion occurred more frequently in screw only group and we obtained more favorable clinical outcomes in screw plus plate group.

Abstract
Large osseous defects of the hindfoot and ankle pose a surgical challenge. Tibiotalocalcaneal (TTC) arthrodesis utilizing a structural allograft may be required to fill the osseous void, preserve limb length and achieve fusion. Several authors have reported small case series on this topic, however outcomes have varied and no systematic review of this data has been published to date. The primary aim of this study is to report rates of osseous union, limb salvage and complications in patients undergoing TTC arthrodesis with a structural allograft. A total of 11 publications were identified that met the inclusion criteria. One hundred seventy-five patients were included with a weighted mean age of 60.5 (range 50-72) years and follow-up period of 29.7 (range 3-62) months. Femoral head allograft was the most commonly utilized structural graft and a retrograde intramedullary nail was the most common fixation construct. Results demonstrated an overall union rate of 67.4%, limb salvage rate of 92.5% and complication rate of 26.6%. Allograft-related complications were rare with an allograft fracture rate of 0.1% and allograft collapse rate of 1.2%. There was no significant difference in union rate when using a retrograde intramedullary nail versus a plate construct (p = .9148). TTC arthrodesis with use of a structural allograft is a viable treatment option for limb salvage when faced with complex hindfoot and ankle pathology involving large osseous defects. Despite high rates of radiographic nonunion, this approach can provide patients with a stable and functional limb while avoiding amputation.

Larger sagittal inter-screw distance/tibial width ratio reduces delayed union or non-union after arthroscopic ankle arthrodesis. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2022:10.1007/s00590-022-03307-x.

Abstract
BACKGROUND Arthroscopic ankle arthrodesis (AAA) has risks of complications, such as delayed union and non-union. The number and direction of the inserted screws have been reported as important factors affecting the time to union of AAA. However, the ratio of inter-screw distance (ISD) to tibial width (TW) in different planes has not been investigated. Therefore, we aimed to explore the effect of this ratio on bone union following AAA. METHODS We retrospectively enrolled 63 patients (64 ankles) undergoing AAA from 2013 to 2019. Then, their age, body mass index (BMI), sex, diabetes mellitus (DM) status, Takakura-Tanaka classification, number of screws and radiographic parameters were analysed. RESULTS The patients had a mean age of 70.3 (range, 45-91) years. Bone fusion was achieved in 57 ankles (89%) in a mean period of 3.3 (range, 2-6) postoperative months. There were four cases of delayed union and three of non-union. No significant differences in age, BMI, sex, DM, Takakura-Tanaka classification, and number of screws could be detected between the groups. However, the sagittal ISD/TW ratio was significantly larger in the union group than in the delayed/non-union group with a cut-off value of 57.0%. CONCLUSION Larger sagittal ISD/TW ratios result in reduced post-AAA delayed union or non-union. The surgeon should be aware that the anterior and posterior screw widths should be approximately 60% or more of the anteroposterior width of the tibia.

Abstract
One of the most challenging problems facing orthopedic surgeons is persistent pain after surgery and certainly is just as frustrating following hindfoot fusion. The hindfoot joints consist of the subtalar, talonavicular, and calcaneocuboid (CC) joints. These joints are commonly fused for degenerative changes, deformity correction, inflammatory or neuropathic arthropathy, tarsal coalition, or primarily after trauma. Goals of hindfoot fusion are a painless plantigrade foot capable of fitting in shoes without orthotics or a brace. Many believe that deformity correction is achievable without inclusion of the CC joint. Managing patient expectations is important when counseling a patient especially regarding potential complications.

Abstract
BACKGROUND The management of displaced intraarticular calcaneus fractures (DIACFs) is a difficult problem with disappointing results from open reduction internal fixation (ORIF). Alternatively, ORIF with primary subtalar arthrodesis (PSTA) has gained increasing popularity. The purpose of this study is to review patient-centered and radiographic outcomes of ORIF plus PSTA using only screws through a sinus tarsi approach. METHODS A retrospective study of patients who underwent ORIF+PSTA for DIACFs was conducted. The same surgical technique was used in all cases consisting of only screws; no plates were used. Delayed surgeries past 8 weeks were excluded. Demographic and radiographic data were collected including worker's compensation claims. Plain radiographs were used to characterize injuries and review outcomes. RESULTS Seventy-nine DIACFs underwent PSTA with a median follow-up of 200 days (n = 69 patients). Median time to weightbearing was 57.5 days postoperatively. Ten fractures were documented as Sanders II, 36 as Sanders III, and 32 as Sanders IV. Sixty-eight fractures (86.1%) achieved fusion on radiographs at a median of 126.5 (range, 54-518) days. Thirty-nine fractures (57.3%) demonstrated radiographic fusion in all 3 predefined locations. Nine of the 14 worker's compensation patients returned to work within the period of observation. There were 8 complications: 3 requiring a secondary operation. Eleven of 79 fractures treated did not go on to achieve radiographic union. CONCLUSION In this retrospective case series, we found that screws-only primary subtalar arthrodesis for the treatment of DIACFs through a sinus tarsi approach was associated with relatively high rates of return to work and radiographic fusion.

Abstract
INTRODUCTION Instability/collapse of the medial column has been associated with many conditions, particularly progressive collapsing foot deformity (PCFD), hallux valgus (HV), and midfoot arthritis (MA). Restoration of first ray length and sagittal plane alignment to restore the foot tripod is essential when treating these deformities. This study aimed to assess early results, healing, and complication rate of a distraction dorsal opening plantarflexion wedge allograft first tarsometatarsal joint fusion (LapiCotton Procedure) in patients with collapse/instability of the medial column. METHODS In this prospective cohort study, we included PCFD, HV, and MA patients that underwent a LapiCotton procedure. Fusion site healing was defined by > 50% bone bridging in both interfaces between allograft wedge and host bone using weight-bearing computed tomography (WBCT) after 3 months. First ray collapse radiographic correction and minor and major complications (deep dehiscence, deep infection, and reoperation) were assessed. RESULTS A total of 22 patients (22 feet) were included (11 PCFD, 6 MA, and 5 of HV patients). Mean follow-up was 5.9 months (range 3-12) and median allograft size was 8 mm (range 5-19 mm). Bone healing was observed in 91% of cases. Two minor complications (9%, both superficial dehiscence) and one major complication (4.5%, deep infection) were observed. Statistically significant improvement of the sagittal plane talus-first metatarsal angle was observed, with mean improvement of 9.4° (95% CI 6.7-12.1°; p < 0.0001). CONCLUSION In this prospective cohort study of 22 patients treated with the LapiCotton procedure for medial longitudinal arch collapse/instability, we observed a low complication rate (9% minor, 4.5% major), high healing rate after 3 months (91%), one clinically stable radiographic non-union (4.5%) and one unstable non-union (4.5%) needing reoperation. Our results demonstrate promising initial results for LapiCotton technique in treating collapse of the medial longitudinal arch in patients with PCFD, MA and HV deformities. Long-term results are needed to confirm these promising results. LEVEL OF EVIDENCE Level II, prospective cohort study.

Abstract
Background: Medial column procedures are commonly used to treat progressive collapsing foot deformity (PCFD) reconstruction. The aim of this research is to present the clinical results of plantar plating for medial naviculocuneiform (NC) arthrodesis when NC joint pathology contributes to medial arch collapse. The authors hypothesized that lag screws with a plantar neutralization plate would result in a satisfactory NC joint fusion rate. Methods: A single-surgeon, retrospective case series was performed on patients with flexible PCFD who underwent NC arthrodesis using lag screws and a contoured neutralization plate applied plantarly across the medial NC joint as part of PCFD reconstruction. Thirteen patients (11 females, 2 males; mean age 53.1 [34-62] years) between 2016 and 2019 were identified for inclusion. Mean follow-up was 25.2 ± 12.7 months. Preoperative and postoperative anteroposterior talo–first metatarsal angle, lateral talo–first metatarsal angle, talonavicular coverage angle, and calcaneal pitch were measured. Union was evaluated radiologically. AOFAS midfoot scores were recorded at final follow-up. Results: All parameters demonstrated a significant improvement. Fusion was confirmed in 11 of 13 patients (85%) at a mean 5.7 ± 2.1 months. One patient required a revision of their NC fusion because of symptomatic nonunion. There were no cases of symptomatic plantar hardware. Conclusion: The results of this small cohort series suggest that lag screw with plantar plate NC arthrodesis yielded generally improved short-term radiographic and clinical outcomes in PCFD patients with medial arch collapse through the NC joint. Level of Evidence: Level IV, retrospective case series.

Abstract
BACKGROUND Medial facet talocalcaneal coalition can be a painful condition. This study aimed to determine clinical and radiographic outcomes of posterior arthroscopic subtalar arthrodesis (PASTA) for adult patients presenting with symptomatic medial facet talocalcaneal coalition and normal hindfoot alignment, with a minimal follow-up of 18 months. METHODS Between June 2017 and July 2019, this procedure was performed on 8 feet (8 patients; mean age, 55 [42-70] years; mean BMI, 29.8 [24.4-45.0] kg/m2). Clinical assessment was performed using Visual Analog Scale for Pain (VAS-P), Foot and Ankle Outcome Score (FAOS) and the 36-Item Short-Form Health Survey (SF-36). Patient satisfaction was assessed at the last available follow-up as "very satisfied", "satisfied" or "unsatisfied". Radiographic analysis was performed using plain radiography, computed tomography (CT) scan and magnetic resonance imaging (MRI). The primary outcome was to determine both clinical and radiographic outcomes. RESULTS The mean follow-up was 25.1 (18.2-34.2) months. The authors found statistically significant improvement on all clinical scores (VASP-P, FAOS and SF-36). They registered 6 "very satisfied" patients, 2 "satisfied" patients and no "unsatisfied" patient. Fusion of the subtalar joint was observed in all patients by 12 weeks and in 5 of them as soon as 8 weeks postoperatively (mean, 9.5 [8-12] weeks). There were no cases of delayed fusion or nonunion of the subtalar joint, superficial or deep infection, neurovascular damage, thromboembolic event, screw breakage, need for hardware removal or revision surgery. CONCLUSION This study found that PASTA is a safe and reliable technique for adult patients presenting with symptomatic medial facet talocalcaneal coalition and normal hindfoot alignment, demonstrating and maintaining clinical improvement at an average follow-up of 2 years.

Subtalar arthrodesis using a single compression screw: a comparison of results between anterograde and retrograde screwing. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:1583-1589. [PMID: 34623469 DOI: 10.1007/s00590-021-03141-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Accepted: 06/28/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION The primary objective of this study was to compare the radiological and clinical results of anterograde and retrograde screwing in subtalar arthrodesis using a single compression screw. The secondary objective was to evaluate the subjective results and consolidation of this procedure. The hypotheses were that isolated screw fixation was sufficient to achieve good consolidation and that there was no difference between the two techniques with a similar rate of bone fusion. METHODS This is a monocentric, retrospective, radio-clinical study based on 99 patients (101 feet), 58 males and 41 females, with an average age of 64 years. The main aetiology was post-traumatic osteoarthritis, which represented 51% of cases. Two groups were formed: group A (52 feet) consisting of fixed arthrodesis with ascending (retrograde) screwing and group D (49 feet) consisting of fixed arthrodesis with descending (anterograde) screwing. The two groups were statistically comparable in terms of demographic data as well as aetiologies and comorbidities. Arthrodeses which were not fused at 6 months were reassessed at one year and in the event of any radio-clinical doubt regarding consolidation, an additional CT scan was prescribed. Average post-operative follow-up was 11 ± 5 years (2-27 years). RESULTS Ninety-two arthrodeses (93%) were fused at one year and 9 were considered to be in non-union, 5 (9.8%) in group A, and 4 (8.3%) in group D. We recorded 30 complications, 22 of which were due to a conflict with the screw head, 18 (34.5%) in group A and 4 (8.3%) in group D (p = 0.03). Conflict between the screw head and the heel led to the removal of the screw after consolidation of the arthrodesis. The clinical results were evaluated using Odom's criteria. Nine per cent of patients described their results as excellent, 29% as good, 51% as satisfactory and 11% found the result to be poor. CONCLUSION The fusion rate for isolated compression screw arthrodesis is good, and there is no difference between anterograde and retrograde screws. However, the discomfort caused by the screw head being insufficiently embedded in the retrograde group led to a non-negligible number of additional surgeries to remove the screw.

Abstract
This review investigated the potential value of computed tomography (CT) scans for the evaluation and management of knee arthritis and arthroplasty. Specifically, we evaluated the following: (1) assessment of arthritis within knee compartments, (2) patellofemoral joint assessment, (3) implant sizing prediction, (4) component alignment, (5) soft-tissue protection, and (6) potential concerns with radiation exposure. To compare if CT or X-ray imaging is more accurate and clinically relevant, a search was performed using Boolean search operators and terms: "CT," "radiograph," "joint alignment," "knee," and "arthroplasty," which yielded 661 results. Studies were evaluated based on (1) assessment of arthritis within knee compartments, (2) patellofemoral joint assessment, (3) implant sizing prediction, (4) component alignment, (5) soft-tissue protection, and (6) potential concerns with radiation exposure. Correlative and comparative analyses of imaging modalities to pre-, intra-, and postoperative clinical and patient-related factors were performed for the 63 included studies. CT scans were found to better detect medial and lateral arthritic changes, bony deformities, subchondral cysts, and cartilage losses. CT scans were shown to 99% accurately predict prosthetic sizes preoperatively. CT scans can also help better visualize surrounding anatomy, such as the posterior cruciate ligament, and have therefore been linked to better soft tissue protection during total knee arthroplasty. Although radiation is a potential concern, newer imaging protocols have comparable exposure to plain radiographs. Compared with plain radiographs, CT scans were found to be more accurate and provide more clinically relevant data. Therefore, the authors recommend the use of CT for the evaluation of certain patients with arthritis and for preoperative planning for knee arthroplasty.

Abstract
Introduction. Segmental bone loss in the hindfoot hinders the chance of successful outcomes. Tibiotalocalcaneal arthrodesis is a reliable option; nevertheless, the risk of nonunion is high. Three-dimensional (3D) printed titanium implants offer a strong scaffold that can be customized and has demonstrated encouraging healing rates. In this study, we described the clinical outcomes and the radiologic union rate of a case series of patients with hindfoot arthrodesis, using a retrograde intramedullary nail associated to a 3D printed titanium cage. Methods. Seven patients undergoing hindfoot arthrodesis, using a retrograde intramedullary nail associated to a custom 3D printed titanium cage, were included. Demographic data were collected. Functional outcomes were assessed using the American Orthopedic Foot and Ankle Score and the Visual Analogue Scale for pain. Hindfoot alignment and radiographic union were evaluated using weight-bearing radiographs and computed tomography scan, respectively. Results. A total of 6 (85%) patients had more than 50% bony bridging. Only 1 patient underwent below knee amputation due to recurrence of chronic osteomyelitis. Two additional patients had minor complications. Conclusion. Tibiotalocalcaneal arthrodesis using customized titanium cages for patients with large bone defects has shown a high rate of union in those at risk of nonunion. However, further research with larger series is needed.Levels of Evidence: Level IV: Case series.

Abstract
Orthobiologics are biologically-derived materials intended to promote bone formation and union. We review evidence on effectiveness and harms of orthobiologics compared to no orthobiologics for foot and ankle arthrodesis. We searched multiple databases (1995-2019) and included clinical trials and other studies with concurrent controls, English language, and reporting patient-centered outcomes, union/time to union, costs/resource utilization, or harms. Studies were organized by orthobiologic used. We describe quality and limitations of available evidence but did not formally rate risk of bias or certainty of evidence. Most of the 21 studies included were retrospective chart reviews with orthobiologics used at surgeon's discretion for patients considered at higher risk for nonunion. Ten studies compared autologous bone graft versus no graft and 2 compared remote versus local graft with few studies of other orthobiologics. All studies reported a measure of fusion and about half reported on function/quality of life. Few studies reported harms. Due to limited reporting, we were unable to assess whether effectiveness varies by risk factors for nonunion (eg, age, gender, smoking status, obesity, diabetes) or whether orthobiologics were cost-effective. Available evidence is of poor quality with small sample sizes, inadequate reporting of risk factors for nonunion, variations in orthobiologics, surgical techniques used, and outcome assessment, and potential selection bias. Research is needed to adequately inform surgeons about benefits and harms and guide patient selection for use, or type, of orthobiologics. Careful assessment of individual patient risk for nonunion is critical prior to orthobiologic use.

Abstract
BACKGROUND The subtalar joint has a complex anatomic function that includes inversion and eversion of the hindfoot, assisting in walking on uneven surfaces. Arthritis is the most common pathological condition affecting this joint and can require fusion. The surgery can be performed open or with arthroscopic assistance. This systematic review assesses articles written on the safety and efficacy of isolated arthroscopic subtalar fusion. METHODS Using MEDLINE and Embase, we systematically reviewed articles published before May 21, 2020. RESULTS Of 395 articles, 17 on a total of 395 patients (409 operations) were included in the review. The average duration of follow-up was 40.0 months (range, 3 to 105 months). Radiographic evidence of union was reported for 95.8% of cases at an average of 11.9 weeks (range, 6 to 56 weeks) postoperatively. Delayed union was reported in 1.0% of patients and nonunion, in 4.3% of patients. In the articles reporting patient satisfaction, including pain relief, 95.4% of patients had positive outcomes. Postoperative complications were reported in 64 patients (16.2%), including 37 (9.4%) with symptomatic implants, 11 (2.8%) with dysesthesia or neuropathic pain, and 3 (0.8%) with postoperative infection. CONCLUSIONS Arthroscopic subtalar fusion is a safe and effective alternative to open subtalar arthrodesis, with high patient satisfaction rates, high union rates at similar follow-up intervals, and low complication rates. The aim of future research should be to determine the ideal cases for this approach as well as the most efficient arthroscopic surgical technique and postoperative rehabilitation to optimize function and union as seen on radiographs.

Abstract
BACKGROUND The outcomes of revision subtalar arthrodesis have received relatively little focus in research compared with primary subtalar arthrodesis outcomes. This study aimed to assess the midterm clinical and radiologic results of subtalar joint revision arthrodesis and to analyze the risk factors that might influence the outcome of this procedure. METHODS We performed a retrospective review of 20 patients after subtalar joint revision arthrodesis for malunion, using interposition of iliac crest bone graft. The mean age was 55.75 years and the average follow-up lasted for 48.93 months. Eighty-five percent of the patients had at least 1 risk factor identified prior to revision. Patients' satisfaction and functional outcomes were evaluated with the American Orthopaedic Foot & Ankle Society Scale (AOFAS), the Foot and Ankle Outcome Score (FAOS), the Foot Function Index (FFI), and dynamic pedobarography. RESULTS A fusion rate of 80% was recorded whereas 20% of the cases ended with a painful pseudarthrosis requiring additional surgery. Pedobarographic measurements demonstrated that loading has a propensity toward the lateral column, but no substantial effect on the gait of patients. In this group, the following patient-reported outcomes were observed: 70% of the patients were satisfied, 20% of the patients found the result fair, and 10% were not satisfied with the results. Compared with the preoperative evaluation, postoperative functional scores showed significant improvement on the FOAS, AOFAS, and FFI outcome scales. CONCLUSION Revision arthrodesis of the subtalar joint remains a challenging issue with a relatively high rate of nonunion, especially in a population of patients with multiple risk factors.

Abstract
PURPOSE To evaluate prospectively the functional outcomes of tibiotalocalcaneal (TTC) arthrodesis with a contemporary retrograde intramedullary nail after a minimum follow-up of five years. METHODS Sixty-one patients with a mean age of 51.3 (range, 18-79) years were included in the study. Functional outcome was assessed using the American Orthopaedic Foot and Ankle Society Ankle Hindfoot score (AOFAS), Short-Form 12-item Health Survey (SF12), and visual analog scales (VAS) for both pain and patient satisfaction. Radiographic evaluation was also assessed. RESULTS The mean post-operative follow-up was 6.8 (range, 5-8) years. Mean AOFAS and SF12 scores significantly improved at the final follow-up (p < 0.001), and the mean VAS for pain significantly decreased (p < 0.001). At the final follow-up, only five (8.2%) patients gave an AOFAS score of less than 50, 52 (85.2%) were satisfied with their surgery, and 32 (52.4%) returned to their employment. There were two tibiotalar joint nonunions that required re-operations, and another patient required re-operation for screw removal. There was no deep infection. CONCLUSIONS The retrograde intramedullary nail provided a stable TTC arthrodesis with a high union rate, acceptable functional outcomes, and a low severe complication rate. This procedure appears to offer a reliable salvage option for TTC arthrodesis in patients with severe ankle and hindfoot degeneration.

Abstract
Introduction: The use of orthobiologics as supplemental treatment for foot and ankle pathologies have increased in the past decades. They have been used to improve the healing of bone and soft tissue injuries. There have been several studies that examined the use of biologics for knee and hip pathologies but the foot and ankle construct has unique features that must be considered.Areas covered: The biologics for foot and ankle injuries that are covered in this review are platelet-rich plasma (PRP), stem cells, growth factors, hyaluronic acid, bone grafts, bone substitutes, and scaffolds. These modalities are used in the treatment of pathologies related to tendon and soft tissue as well as cartilage.Expert opinion: The utilization of biological adjuncts for improved repair and regeneration of ankle injuries represents a promising future in our efforts to address difficult clinical problems. The application of concentrated bone marrow and PRP each represents the most widely studied and commonly used injection therapies with early clinical studies demonstrating promising results, research is also being done using other potential therapies such as stem cells and growth factors; further investigation and outcome data are still needed.

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.

BACKGROUND Here, we determined whether teriparatide treatment would increase fusion rates after foot and ankle arthrodesis by comparing treatment results between patients with high-risk factors for nonunion who received teriparatide against those who did not. METHODS We retrospectively reviewed 66 consecutive patients who underwent foot and ankle arthrodesis. The inclusion criterion was the presence of at least one of the following risk factors for nonunion after previous foot and ankle arthrodesis: deformity, bone defects, avascular necrosis, and nonunion. Sixteen patients were finally enrolled and divided into 2 groups: 8 patients received teriparatide treatment after fusion surgery (PTH group), and 8 patients did not (control group). RESULTS The fusion rate was significantly greater in the PTH group than in the control group (100% vs 50%). Four patients in the control group developed nonunion, 3 of whom underwent revision fusion; however, all patients received the teriparatide treatment after revision surgery and subsequently achieved union. No significant differences in demographics, fusion sites, and complication rates were found. CONCLUSION Though the sample size was small, the current study suggests that teriparatide administration may improve fusion rates in patients with high-risk factors for nonunion after foot and ankle arthrodesis.

Minimally invasive technique for stage III adult-acquired flatfoot deformity: a mid- to long-term retrospective study. INTERNATIONAL ORTHOPAEDICS 2020; 45:217-223. [PMID: 32870346 DOI: 10.1007/s00264-020-04724-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Accepted: 07/08/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE The purpose of this study was to present the functional, radiological, and quality of life outcomes of a series of stage III adult-acquired flatfoot deformity corrections using an original operative approach based on minimal incision surgery (MIS). METHODS Sixty-two patients (67 feet) with a symptomatic stage III flatfoot deformity were treated using a modified double arthrodesis by MIS. The mean age was 63 years (range, 50 to 81) and the mean follow-up was 6.6 years (range, 3.2 to 11.5). Clinical, radiological, American Orthopaedic Foot and Ankle Society Hindfoot score (AOFAS score), quality of life (SF-36), and satisfaction scores were collected retrospectively. RESULTS The mean AOFAS score improved by 54.27 (95% [CI], 57.27-51.3; P < 0.0001), and the SF-36 improved by a mean of 17.5 points (95% CI, 1.4-20.9) in the physical component summary (PCS). Deformity correction was confirmed by a significant improvement in the x-ray measurements (six angles). Bony union was observed in 89.5% of cases (60/67). In all, nine patients (13.4%) needed a secondary surgery: three for talonavicular nonunion, four for progression of the flatfoot deformity, and two for screw protrusion. No cases of superficial infection, wound dehiscence, or avascular necrosis of the talus were observed. CONCLUSION The present series represents the largest study of stage III flatfoot correction using MIS with a mid- to long-term follow-up. Because the data showed clinical and functional improvement after surgery with fewer complications, this technique may be ideal for patients at risk of complications. Graphical abstract.

Abstract
BACKGROUND Biomechanical studies have shown a higher compressive force and higher torsional stiffness for fixation with three screws compared to two screws. However, clinical data to compare these fixation techniques is still lacking. METHODS A retrospective analysis of 113 patients was performed, who underwent isolated subtalar fusion between January 2006 and April 2018. RESULTS Revision arthrodesis was required in 8% (n=6/36) for 3-screw-fixation and 38% (n=35/77) for 2-screw-fixation. For 3-screw-fixation, non-union, was observed in 14% (n=5/36) compared to 35% (n=27/77) in 2-screw fixation. Non-union (p=.025) and revision arthrodesis (p=.034) were significantly more frequent in patients with 2 screws. A body mass index ≥30kg/m2 (p=.04, OR=2.6,95%CI:1.1-6.3), prior ankle-fusion (p=.017,OR=4.4,95%CI:1.3-14.5) and diabetes mellitus (p=.04,OR=4.9,95%CI:1.1-17.8) were associated with a higher rate of revision arthrodesis. CONCLUSIONS Our findings suggest that successful subtalar fusion is more reliably achieved with use of three screws. However, future prospective studies will be necessary to further specify this recommendation.

Abstract
BACKGROUND Intramedullary fusion bolts (FB) were introduced to stabilize the medial column of the instable Charcot foot (ICF), but complications as bolt loosening or breakage are frequent. We compared the use of a standard FB and a high-profile threaded FB with a grit-blasted surface. We hypothesized that implant related complications occurred less often and osseous consolidation of fusion sites was more distinctive using the latter type of FB. METHODS Consecutive patients suffering from an ICF were stabilized with a high-profile threaded and surface-modified FB (HTFB) (n=20) or with a standard FB (n=20) which was placed into the first ray. Additional bolts and dorsal low-profile plates were applied in every patient. In a retrospective assessment osseous consolidation of the fusion sites was analyzed at 3 month and quantified by CT scan. At 3 and 12 month longitudinal foot arch collapse and rate of bolt loosening were assessed. RESULTS Compared to the control group, the HTFB group reached significant higher consolidation after 3 month. No dislocation and a single bolt breakage was observed in the HTFB group after the fourth month, while the control group included 3 patients with bolt dislocation at 3±1 month and 5 patients with bolt breakage at 6±1.8 month. Compared to preoperative values, the improvement of Meary's angle after one-year was significant higher in the HTFB group (23.4°±14) than in controls (11.7°±13). CONCLUSIONS Modification of bolt design improves the stability of the medial column: A higher rate of osseous consolidation of the medial column leads to lower rate of bolt dislocation/breakage and finally to permanently erected longitudinal foot arch. Initially disappointing results following medial column stabilization with fusion bolts can be rejected by modifications of bolt design and its technical application.

Abstract
Background: Tibiotalocalcaneal (TTC) arthrodesis implementing adjunctive allografts is a method of limb salvage for patients with complex hindfoot osseous deficits, though outcome results are limited. The purposes of this study were to assess functional and radiographic outcomes after TTC arthrodesis with femoral head allograft and retrospectively identify prognostic factors. Methods: The authors reviewed 24 TTC arthrodesis procedures with bulk femoral head allografts performed by a single surgeon from 2004 to 2016. Radiographic union at the ankle and subtalar joints along with stability of the allograft were assessed. Patients who had clinically successful arthrodeses were contacted to score the Foot and Ankle Ability Measure-Activities of Daily Living (FAAM-ADL) questionnaire, Visual Analog Scale (VAS) for pain, and Short Form-12 (SF-12) at a mean of 58.0 months (range, 28-102) postoperatively. Results: Complete radiographic union of involved joints was achieved in 15 patients (63%) and in 75% (36/48) of all joints; 21 ankles (88%) were assessed to be radiographically stable at final follow-up. Three patients (13%) underwent revision arthrodesis at a mean of 18.9 months postoperatively, and 21 patients (88%) did not require additional surgery as of final follow-up. Patients significantly improved to a mean FAAM-ADL score of 71.5 from 36.3 (P < .001). The mean VAS for pain significantly improved from 77.2 to 32.9 (P < .001). Male sex (P = .08) and a lateral operative approach (P = .03) both resulted in worse outcomes. Conclusion: Use of a femoral head allograft with TTC arthrodesis can offer improved functional scores and sustained radiographic outcomes.Level of Evidence: Level IV: Case series.

Abstract
BACKGROUND Over the last twenty years, minimally invasive ankle arthrodesis has evolved into a well-tolerated and safe procedure. It has grown in favor to open ankle arthrodesis due to shorter length of stay and fewer complications recorded. This paper aims to compare the clinical outcomes of arthroscopic vs open ankle arthrodesis at 24-months followup. METHODS From 2004 to 2015, we reviewed a prospectively collected database in a tertiary hospital foot and ankle registry. 28 feet that underwent arthroscopic ankle arthrodesis were matched to 56 feet that underwent open ankle arthrodesis for age, sex and body mass index (BMI). Visual analogue scale (VAS) scores, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-hindfoot Scores and Short Form Health Survey (SF-36) were obtained to assess clinical outcomes. These parameters were collected before surgery, at 6months and 24months after surgery. RESULTS The arthroscopic group demonstrated significant less pain in the perioperative period (arthroscopic: 1.9±1.2, open: 3.8±1.1, p<0.001) and shorter length of hospitalization stay (arthroscopic: 2.1±0.7 open: 3.5±1.7, p<0.001). Patients who underwent arthroscopic ankle arthrodesis also reported a higher SF-36 score on physical functioning at 6months (arthroscopic: 58.4±27.1, open: 47.1±24.0, p<0.05) and higher AOFAS Ankle-hindfoot Scale score at 24-months (arthroscopic: 78.9±18.9, open: 68.9±24.7, p<0.05). There were no postoperative complications in the arthroscopic group but 11 in the open group, including 9 which required followup operations. There was no significant difference in length of operative procedure between both groups. CONCLUSIONS We conclude that the arthroscopic group displayed better clinical outcomes compared to the open group at the 24months followup. The advantages of arthroscopic ankle arthrodesis include significantly less perioperative pain, higher AOFAS Ankle-hindfoot scores at 24months, shorter length of stay, fewer postoperative complications and followup operations.

Abstract
PURPOSE First metatarsophalangeal (MTPJ1) fusion represents the gold standard treatment for end-stage hallux rigidus (HR). The aim of this study was to assess efficacy and safety of A-PRF in promoting union after MTPJ1 arthrodesis. Our hypothesis was that the use of A-PRF may reduce the non-union rate and the time to fusion in the treatment of HR. METHODS 14 patients that had undergone MTPJ1 arthrodesis with A-PRF adjunction with 21 standard MTPJ1 fusions were retrospectively reviewed. The fusion rate and time to fusion (clinically and radiographically) were assessed at 6, 12 weeks and at the longest follow-up; the clinical status at final follow-up through forefoot AOFAS, EQ5d, SEFAS and VAS-pain scores; the complication rate. RESULTS At 6-weeks, bony union was achieved in 100% of patients in the A-PRF group compared to 70% in the control group, but this difference was not statistically significant (p=0.22). At final follow-up (41 months), union rate in the control group reached 92% (one non-union). AOFAS, VAS and EQ-5d scores showed similar results for the two groups (p=0.86, p=0.12 and p=0.61, respectively); only SEFAS score revealed a difference favoring the A-PRF group (p=0.04). No revision surgery or complication was recorded in any group. CONCLUSIONS A tendency for increased union rate was mainly found at 6 weeks in patients treated with MTPJ1 fusion associated to A-PRF compared to isolated fusion. The use of A-PRF was not associated with an increased complication rate at final follow-up. LEVEL OF EVIDENCE Level 3, therapeutic study, retrospective comparative study.

Abstract
BACKGROUND Our understanding of the biology of ankle arthrodesis is based largely on work in spine and long bone animal models. However, the local soft tissue and vascular anatomy of the foot and ankle is different from that of the spine. Accordingly, the objective of this study was to develop a small animal ankle arthrodesis model. METHODS A total of 12 Lewis rats successfully underwent ankle arthrodesis with stabilization consisting of a single Kirschner wire across the prepared tibiotalar joint. Based on high nonunion rates with this initial procedure, a modification was made consisting of a second pin crossing the joint. A total of 6 rats underwent the second procedure. Radiographs were taken postoperatively and in 2-week intervals up to 10 weeks. Micro computed tomography (µCT) and histological analysis was conducted at 10 weeks to assess the fusion mass. Osseous bridging of greater than 50% across the tibiotalar joint was deemed a successful fusion. RESULTS µCT analysis determined that 11 of the 12 rats in the single-pin cohort developed nonunions (8.3% fusion rate). In the dual-pin cohort, all 6 animals successfully fused (100% fusion rate). Histological analysis supported the radiographic imaging conclusions. CONCLUSION While the initial procedure had a high nonunion rate, enhancing the stability of the fixation greatly increased the union rate. CLINICAL RELEVANCE The present work demonstrates the first reliable small animal ankle arthrodesis model. We believe that this model can be used in the development of novel therapies aimed at decreasing complications and increasing fusion rates.

Abstract
The definition of consolidation after ankle arthrodesis can be challenging in some situations. Computed tomography has increased diagnostic accuracy; however, there are still no clear criteria for nonunion. In this context, arthroscopy with direct visualization of the arthrodesis may provide crucial data to inform the choice of treatment. The present report illustrates a case in which arthroscopy prompted a change in treatment strategy. More extensive surgery, with the potential for greater morbidity due to revision arthrodesis, could be avoided.

Abstract
UPDATE This article was updated on November 7, 2019, because of a previous error. On page 1909, in the section entitled "Discussion," the sentence that had read "Radiographic nonunion rates of 69.2% and 45.6% were observed at 6 months for ACBM and autograft, respectively, as measured on CT scans; however, these nonunion rates do account for patients who were considered to have attained fusion according to traditional methods, including absence of pain and swelling and presence of arthrodesis on radiographs" now reads "Radiographic nonunion rates of 69.2% and 45.6% were observed at 6 months for ACBM and autograft, respectively, as measured on CT scans; however, these nonunion rates do not account for patients who were considered to have attained fusion according to traditional methods, including absence of pain and swelling and presence of arthrodesis on radiographs."An erratum has been published: J Bone Joint Surg Am. 2019 XXX. BACKGROUND Subtalar arthrodesis effectively treats subtalar joint arthritis when other interventions have failed. Nonunion is a known complication of subtalar arthrodesis, with reported rates ranging from 5% to 45%. Historically, open arthrodesis has been performed with use of autologous bone graft; however, there are inherent disadvantages to autologous bone graft, including donor-site morbidity. Mesenchymal stem cells, when placed on a cellular scaffold, have shown promise as an alternative to autologous bone graft. The purpose of this multicenter, randomized controlled trial was to assess the safety and efficacy of an adipose-derived cellular bone matrix (ACBM) composite made with live cells compared with autograft in subtalar arthrodesis. METHODS A total of 140 patients were enrolled in a prospective, randomized (1:1) controlled trial performed at 6 clinical sites in the U.S. End points, including radiographic, clinical, and functional outcomes, were assessed over 2 years of follow-up. RESULTS A total of 109 patients underwent arthrodesis with ACBM (52 patients) and autograft (57 patients). At 6 months, fusion was achieved in 16 patients (30.8%) in the ACBM group and 31 patients (54.4%) in the autograft group as measured on computed tomography (p = 0.024), and in 41 patients (78.8%) in the ACBM group and 50 patients (87.7%) in the autograft group as assessed on clinical and radiographic evaluation (p = 0.213). Quality-of-life outcome measures demonstrated significant functional improvement from baseline for both groups. Fewer cases of serious adverse events occurred in the autograft group (10.5%) compared with the ACBM group (23.1%) (p = 0.078). CONCLUSIONS In patients who require subtalar arthrodesis, the use of ACBM demonstrated lower rates of radiographic fusion compared with treatment with autograft. The nonunion rate in the autologous group, as measured on computed tomography, was high. Good clinical outcomes were achieved in spite of the high non-union rates.

Abstract
BACKGROUND Joint arthrodesis often employs autograft to promote union; graft harvesting can lead to perioperative morbidity. A Canadian randomized controlled trial (RCT) demonstrated that recombinant human platelet-derived growth factor BB homodimer (rhPDGF-BB) combined with beta-tricalcium phosphate (β-TCP)-collagen was a safe, effective alternative to autograft. This multicenter North American RCT compared the safety and efficacy of rhPDGF-BB/β-TCP-collagen with autograft for ankle and hindfoot fusion. Subclassification using propensity scores (PS) incorporated patients from previous trials for enhanced statistical power for noninferiority testing and broader review of treatments. METHODS Patients requiring ankle or hindfoot arthrodesis and supplemental bone graft were treated with rhPDGF-BB/β-TCP-collagen (n = 69) or autograft (n = 35). Outcomes included joint fusion on computed tomography (24 weeks), clinical healing status, visual analog scale (VAS) pain, Short-Form 12 (SF-12), American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale, and Foot Function Index (FFI) scores over 52 weeks. PS methodology addressed potential selection bias arising from pooling data among these patients and 2 previous RCTs with similar inclusion criteria, surgical techniques, graft harvest techniques, and outcomes. All 132 rhPDGF-BB/β-TCP-collagen-treated patients and 167 of 189 candidate autograft-treated controls were selected for comparison by an independent statistician blinded to outcomes. RESULTS In the PS subclassification, 68.1% treatment patients and 68.4% controls achieved >50% osseous bridging at fusion sites. Clinical healing status was achieved in 84.8% of treated patients and 90.7% of controls at 52 weeks. Clinical, functional, and quality of life results demonstrated noninferiority of rhPDGF-BB/β-TCP-collagen to autograft. Safety-related outcomes were equivalent. CONCLUSION PS subclassification analysis of 3 RCTs demonstrated that rhPDGF-BB/β-TCP-collagen was as effective as autograft for ankle and hindfoot fusions, with less pain and morbidity than treatment with autograft. LEVEL OF EVIDENCE Level I, prospective randomized study.

Abstract
Originally described as a means to address fixed deformities or uncontrolled movement of the hindfoot observed in paralytic foot deformities, triple arthrodesis has evolved into a powerful procedure for the correction of a variety of foot deformities. Over the past decade, multiple advances have been made with respect to diagnostic imaging, fixation options, bone graft substitutes, and postoperative regimens. While this operation requires experience and skill to execute, when properly performed, it allows for correction of deformity and a plantigrade and ideally pain-free foot for ambulation. The purpose of this review is to highlight advances in the procedure and its application to the rigid planovalgus foot. Level of Evidence: Level V, review.

Abstract
Achieving fusion in osseous procedures about the foot and ankle presents unique challenges to the surgeon. Many patients have comorbidities that reduce osseous healing rates, and the limited space and high weightbearing demand placed on fusion sites makes the choice of bone graft, bone graft substitute, or orthobiologic agent of utmost importance. In this review, we discuss the essential characteristics of grafts, including their osteoconductive, osteoinductive, osteogenic, and angiogenic properties. Autologous bone graft remains the gold standard and contains all these properties. However, the convenience and lack of donor site morbidity of synthetic bone grafts, allografts, and orthobiologics, including growth factors and allogenic stem cells, has led to these being used commonly as augments.

Abstract
BACKGROUND The purpose of this study was to assess the outcomes of distal tibial structural allograft to obtain a stable TTC fusion. METHODS Retrospectively, ten patients were carried out with a minimum one year follow-up. The median age was 72 (33-81). The median BMI was 28 (24-33). Indications for TTC arthrodesis included failed total ankle arthroplasty (n=7 patients), prior nonunion (n=2 patients), and a trauma injury. RESULTS Union rate was 80%. The median initial height of the distal tibial allograft was 19mm (14-24mm). In seven cases the allograft did not lose height. The AOFAS score median was 69 (31-84). SF-12 median physical component was 39 (30-53), and 59 (23-62) for mental component. The VAS median was 2 (0-8). CONCLUSIONS TTC using distal tibial allograft shows a lower rate of collapse than other structural grafts and provides a fusion rate higher or in accordance with the literature.

Abstract
A review of 195 first ray arthrodeses fixated with a twin-plate biplanar construct, without interfragmentary compression, is presented. This fixation construct was evaluated in a consecutive cohort of patients undergoing first metatarsophalangeal joint (MTP) arthrodesis or the first tarsometatarsal joint (TMT) arthrodesis. Multiple radiographs were used to assess the progression of healing at the following postoperative time frames: 4 to 9 weeks, 10 to 12 weeks, >12 weeks, and the final follow-up. In total, 85 feet underwent first MTP arthrodesis, and 110 feet underwent first TMT arthrodesis. At the final radiographic follow-up, 97.44% of all cases had shown progressive osseous gap filling at the arthrodesis site, stable position of the bone segments, and intact hardware without loosening, 98.24% of the first MTP arthrodesis group and 96.82% of the first TMT arthrodesis group. Five (5.43%) feet had the presence of lucency at the fusion interface at the final follow-up, without positional change or hardware failure. Four (1.8%) feet had a failure of the hardware, loss of position, or frank gapping at the fusion site. Lucency decreased consistently over time in this series of patients (p < .00001). Progressive increase in callus density at the fusion site on serial radiographs was noted to be a consistent finding for both procedures and was the primary indicator of secondary bone healing at the noncompressed, relatively stable arthrodesis site. Our results confirm that biplanar plating construct without interfragmentary compression produces high fusion rates following the first MTP or TMT arthrodesis, with early weightbearing.

Abstract
Nitinol has been shown to generate durable compression under loading via pseudoelastic shape memory. The purpose of this study was to evaluate the effectiveness of a hindfoot arthrodesis nail with an internal pseudoelastic nitinol compression element. Patients who had undergone tibiotalocalcaneal arthrodesis from 2013 to 2016 were identified at 2 tertiary referral centers (12-week follow-up minimum). Patients managed with a tibiotalocalcaneal nail with an internal nitinol compression element were identified for review. Sagittal computed tomographic scan reformats were reviewed to calculate a percentage of joint surface bony union. Intraoperative and postoperative radiographs were compared to calculate postoperative screw position change generated by the nitinol element, a surrogate for postoperative unloading of compressive forces. Thirty-three patients were included in analysis and 81% of patients had successful union of both tibiotalar and subtalar joints. Overall, 90% of all arthrodesis surfaces united. The union rate of arthrodesis surfaces among patients without Charcot osteoarthropathy was 94%. A history of Charcot was identified as a risk factor for subtalar nonunion (p = .04) and was associated with less complete computed tomography-based tibiotalar union: 94% versus 71% (p < .01). The posterior-to-anterior screw translated an average of 3.9 mm proximally relative to the rigid portion of the nail from intraoperative to initial postoperative radiographs (p < .0001). High rates of computed tomography-confirmed union were demonstrated in the face of challenging clinical scenarios. Shortening of the pseudoelastic nitinol element occurs early in the postoperative period, indicating continued unloading of the nitinol compression element through the arthrodesis sites after initial implantation.

Three-Dimensional Reconstruction of Foot in the Weightbearing Position From Biplanar Radiographs: Evaluation of Accuracy and Reliability. J Foot Ankle Surg 2019; 57:931-937.

Abstract
The initial assessment and postoperative monitoring of patients with various abnormalities of the foot in clinical routine practice is primarily based on the analysis of radiographs taken in the weightbearing position. Conventional x-ray imaging, however, only provides a 2-dimensional projection of 3-dimensional (3D) bony structures, and the clinical parameters assessed from these images can be affected by projection biases. In the present work, we addressed this issue by proposing an accurate 3D reconstruction method of the foot in the weightbearing position from low-dose biplanar radiographs with clinical index measurement assessment for clinical routine practice. The accuracy of the proposed reconstruction method was evaluated for both shape and clinical indexes by comparing 3D reconstructions of 6 cadaveric adult feet from computed tomographic images and from biplanar radiographs. For the reproducibility study, 3D reconstructions from the biplanar radiographs of the foot of 6 able-bodied subjects were considered, with 2 observers repeating each measurement of anatomic landmarks 3 times. Baseline assessment of important 3D clinical parameters was performed on 17 subjects (34 feet; mean age 27.7, range 20 to 52 years). The average point to surface distance between the 3D stereoradiographic reconstruction and the computed tomographic scan-based reconstruction was 1 mm (range 0mm to 6mm). The selected radiographic landmarks were highly reproducible (95% confidence interval <2.0 mm). The greatest interindividual variability for the clinical parameters was observed for the twisting angle (mean 87°, range 73° to 100°). Such an approach opens the way for routine 3D quantitative analysis of the foot in the weightbearing position.
