Displaced intra-articular calcaneus fractures (DIACFs) are difficult injuries to treat and are often encountered by orthopedic surgeons. For DIACFs treated nonoperatively or with open reduction internal fixation (ORIF), a common complication is painful subtalar arthritis and the need for a secondary subtalar fusion, which prolongs the overall recovery time. One treatment option to address this sequela involves ORIF with subtalar fusion as the primary treatment. We describe a reproducible, minimally invasive surgical technique for primary ORIF with subtalar fusion when the calcaneal tuberosity is amendable to cannulated screw fixation to treat these complex calcaneal fractures. Our technique offers advantages compared to other techniques in that it avoids screw traffic, allows easy bony compression of the subtalar joint, and minimizes soft tissue damage via percutaneous screw fixation. Fourteen fractured calcanei in 12 patients underwent our technique and all achieved bony union with a median time to fusion of 107.5 days (range, 54–530 days). Eight patients returned to work with the remaining 4 patients having an unknown work status at last follow-up, although 2 of these 4 patients resumed normal activities. Only 1 patient experienced a complication, which was an infection after achieving bony union, and was treated with successful hardware removal and our infection protocol. Overall, we conclude our surgical technique offers a successful option in the treatment of DIACFs when the calcaneal tuberosity is amendable to cannulated screw fixation. [ABSTRACT FROM AUTHOR]

Background: Prior literature has demonstrated that ipsilateral hindfoot arthrodesis may increase the risk for reoperation after total ankle arthroplasty (TAA) and that simultaneous hindfoot arthrodesis with TAA could result in short-term clinical and radiologic improvements. The purpose of this study is to compare the reoperation rates after TAA with prior hindfoot arthrodesis vs simultaneous arthrodesis and TAA. Methods: Patients who underwent primary TAA were identified in the PearlDiver database. Patients were sorted into 2 study cohorts: hindfoot arthrodesis prior to TAA and simultaneous arthrodesis and TAA. Propensity matched control cohorts were identified for each study group. Multivariate analysis was conducted to account for any confounding variables and covariates when identifying differences in complications between cohorts. Results: 297 patients underwent TAA with prior hindfoot arthrodesis and 174 underwent TAA and hindfoot arthrodesis concurrently. The incidence of reoperation (13.8% vs 5.2%, P <.001) and infection (12.6% vs 5.9%, P =.011) for the simultaneous cohort was higher when compared to the matched control cohort. In contrast, there was no statistically significant difference when comparing the prior arthrodesis cohort to the matched control cohort in reoperation rates (5.1% vs 4.7%, P =.787) or infection rates (4.4% vs 4.8%, P =.734). Those undergoing simultaneous procedures had increased incidences of reoperation, wound complications, infection, and emergency department visits (P <.0167) when compared to the TAA with prior arthrodesis cohort. Conclusion: Patients undergoing TAA and hindfoot arthrodesis concurrently were found to have higher rates of reoperation and infection when compared to the matched control cohort. In contrast, there was no difference in these rates in patients undergoing TAA with prior hindfoot arthrodesis compared with their matched control cohort. Patients undergoing simultaneous procedures had increased rates of reoperations, wound complications, infection, and emergency department visits compared to the TAA with prior arthrodesis cohort.

Background: Subtalar joints stability is greatly dependent on the facets on the calcaneus for talus articulation. Understanding the various variances in these features will help clinicians develop a more effective and individualized strategy that will yield the greatest outcomes. Our study aimed to examine the morphometry and morphology of the articular facets for the talus on the calcanei in humans. Methodology: In the present descriptive study, an analysis was conducted on 300 calcanei, dry bones of human adults of undetermined sex and age. The facet on every calcaneus for articulation with the talus was studied meticulously. Statistical analysis was done to determine the percentage and P value. Results: In the present study out of 300 calcanei studied, type IB with a nonconstricted articular facet pattern was found in 49.67% of calcanei, followed by type I A with a constricted articular facet present in 27% of calcanei. This was followed by type IIA in 14% of calcanei, type IIB in 5.67% of calcanei, type II C was found in only 0.67% of calcanei, type III was found in 2.33% of calcanei, and Types IV and V were found in 0.33%. Conclusion: This research elucidates the interrelationship among the articular facets of the talus and its clinical implications. Identifying distinct facet types is crucial for implementing suitable interventions to prevent injuries and ensure optimal joint function. Understanding the morphometric characteristics of these facets will undoubtedly aid orthopedic surgeons in managing disorders of the ankle and subtalar joints effectively.

While adjacent joint arthritis is a recognized long-term downside of primary tibiotalar arthrodesis (TTA), few studies have identified risk factors for early subtalar arthrodesis (STA) after TTA. This study aims to identify the risk factors for STA within the first few years following TTA. All patients older than 18 years undergoing TTA between 2008 and 2016 were identified retrospectively. Demographic data and comorbidities were collected alongside prior operative procedures, postoperative complications, and subsequent STA. Pre-and postoperative Kellgren-Lawrence osteoarthritis grade of the subtalar joint and postoperative radiographic alignment were obtained. A total of 240 patients who underwent primary TTA were included in this study with median follow up of 13.8 months. Twenty patients (8.3%) underwent STA after TTA due to symptomatic nonunion of TTA in 13 (65%), progression of symptomatic subtalar osteoarthritis (OA) in 4 (20%), and symptomatic nonunion of primary TTA combined progressively symptomatic subtalar OA in 2 (10%). Preoperative radiographic subtalar OA severity and postoperative radiographic alignment were not correlated with subsequent STA. Diabetes mellitus, Charcot arthropathy, neuropathy, alcohol use, substance use disorder, and psychiatric disease were significantly associated with having a subsequent STA. The most common postoperative contributing factor for subsequent STA following primary TTA was the salvage of symptomatic ankle nonunion rather than subtalar joint disease. Patients considering an ankle fusion should be counseled of the risk of subsequent STA, especially if they have risk factors that include diabetes, Charcot arthropathy, neuropathy, alcohol use, substance use disorder, or psychiatric disease.

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. 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. 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. In the present study, bone graft could not effectively reduce the risk of nonunion and improve the outcome. [ABSTRACT FROM AUTHOR]

Background: Principle of distraction and an indirect reduction was used to promote healing of fractures and adequate regeneration of cartilage at the subtalar joint. Aims and Objectives: The study was aimed to elaborate and develop role of Ilizarov as an alternative biological method to manage intraarticular fracture calcaneum with minimal chances of infection. Materials and Methods: Twenty-one patients were studied and the mean age of patients was 40.7 years (span: 20 to 65 years). Sanders CT classification was used to divide into type II, 11 (52.38%); type III, 7 (33.33%) and type IV, 3 (14.28%). The average followup was 17.2 months (range: 6 to 24 months). AOFAS scale for ankle and hindfoot was used for assessment of patients- 7 (33.33%) excellent, 7 (33.33%) good, 3 (14.28%) fair, and 4 (19.04%) poor results. The average score was 81.5 ±12.1. The mean period of treatment was 12 weeks (10 to 14 weeks). Results: On radiological assessment, Bohler’s angle change was 19.7±4.4 degrees to 33.51± 5.7 degrees; angle of Gissane changed from 126.4 ± 6.7 degrees preoperatively to 124.9 ± 6.9 degrees postoperatively; calcaneal height changed 40.14 ± 1.98 mm preoperatively to 43.33 ± 1.87 mm and width changed 45.09 ±3.65 mm preoperatively to 43.09 ±3.16 mm postoperatively and reduction malalignment >10 degrees in 5 patients. Superficial skin infection at wire insertion sites was the most common complication encountered in our cases. Conclusion: Our results with this ergonomic technique in a small number of 21 non-randomised cases with a mean followup of 17.2 years attribute towards an alternate surgical substitute to conventional open reduction techniques in the treatment of intra-articular fractures of calcaneum having lesser rate of complications.

Background: Tibiotalar and subtalar arthritis requiring tibiotalocalcaneal (TTC) fusion can be technically challenging and is dependent on reliable fusion for a good clinical outcome. Initial data regarding bone marrow aspirate concentrate (BMAC) has shown promise in use as an aide in both fracture and fusion healing. The purpose of this study is to determine the outcomes in TTC fusion when utilizing BMAC as an adjunct. Methods: Twenty consecutive patients who underwent TTC fusion with BMAC adjunct between March 2013 and November 2017 were retrospectively screened for inclusion. Patients were included regardless of comorbidities or risk factors for non-union, and only excluded if they did not have a minimum of 12 months of clinical and/or radiographic chart data. Follow-up was obtained at regular intervals of 6 weeks, 3 months, 6 months and 1 year. Modified RUST scores were applied to grade bony union in a blinded fashion by two orthopedic trauma fellowship-trained surgeons and agreement was assessed via intraclass correlation coefficient (ICC). Results: Twenty patients were screened and 12 met inclusion criteria for analysis. Majority were male (66.6%) at a mean age of 55.4 years and they were all treated via TTC fusion for a diagnosis of tibiotalar and subtalar arthritis. There were no postoperative complications and no reoperations in this cohort; no donor site morbidity was associated with BMAC. By the 3-month follow-up timepoint, all but one patient received a minimum modified RUST score of 10 indicating bony union (ICC 0.91); by the 6-month time point (ICC 0.94), all 12 patients were deemed united. Conclusion: BMAC as an adjunct in the setting of TTC fusion is a safe treatment option that can promote reliable, consistent bony fusion with minimal complications. [ABSTRACT FROM AUTHOR]

Background: Open subtalar arthrodesis is the standard treatment for subtalar arthritis. Posterior arthroscopic subtalar arthrodesis (PASTA) has recently gained increasing popularity due to a shorter recovery time and better cosmesis. However, studies comparing outcomes and complications between these 2 techniques are limited. Methods: In total, 56 patients with subtalar joint arthritis were prospectively randomized to 2 parallel groups to receive either PASTA (n = 28 patients) or open subtalar arthrodesis (n = 28 patients). The minimum follow-up period was 12 months. Primary outcome was union rate confirmed on postoperative computed tomography (CT) scan. Secondary outcomes were union time; visual analog scale (VAS), Short Form–36 (SF-36), and Foot and Ankle Ability Measure (FAAM) scores; tourniquet time; and complications. Results: Union time (9.4 vs 12.8 weeks) and recovery time (time to return to activities of daily living [8.4 vs 10.8 weeks], work [10.6 vs 12.9 weeks], and sports [24.9 vs 32.7 weeks]) were significantly shorter with PASTA than with the open technique (P <.05 all). Both techniques led to significant improvements in all functional outcomes (FAAM, SF-36, and VAS scores; P <.01 all); however, there was no significant difference between the techniques in these outcomes (P >.05 all). Other outcomes, including tourniquet time (55.8 vs 67.2 min), union rate (96.3% vs 100%), and complication rate, were not significantly different between the techniques. Conclusion: Both open and PASTA techniques led to significant improvements in pain and function in patients with isolated subtalar joint arthritis. Although short-term functional outcomes and complication rates were not significantly different between the techniques, the PASTA technique was better at shortening the union and recovery times. Level of Evidence: Level I, prospective multicenter randomized controlled trial. [ABSTRACT FROM AUTHOR]

The article discusses how calcaneal malunion can develop postoperatively from inadequate reduction or loss of reduction, resulting in subtalar arthritis with significant deformity. It mentions typical deformities include loss of calcaneal height and varus malalignmen. It presents a technique that can restore the height of the calcaneus and arch of the foot.

Introduction/Purpose: The incidence of primary total ankle arthroplasty (TAA) in the treatment of end-stage ankle arthritis has increased substantially over the last decade. TAA may be performed alone or in conjunction with additional procedures including subtalar (ST) or triple arthrodesis as end-stage ankle arthritis is often associated with degenerative disease affecting neighboring joints. Prior literature has demonstrated that the ipsilateral hindfoot arthrodesis may increase the risk for revision after TAA and that simultaneous ST arthrodesis with TAA could result in significant short term clinical and radiologic improvements. However, there is limited research comparing staged versus simultaneous hindfoot arthrodesis with concomitant TAA. The purpose of this study is to compare the reoperation rates after TAA with simultaneous hindfoot arthrodesis versus staged hindfoot arthrodesis followed by TAA. Methods: Patients who underwent primary TAA from 2015-2022 were identified in the PearlDiver database using international classification of diseases (ICD) and current procedural (CPT) codes. Patients were only selected if they contained 1-year database follow-up after the index TAA. Patients were sorted into three cohorts: (1) primary TAA without any history of hindfoot arthrodesis (control), (2) those with staged hindfoot arthrodesis prior to TAA, and (3) those with hindfoot arthrodesis at the same time as TAA. Demographic characteristics including age, gender, and Charlson Comorbidity Index (CCI) were assessed for each cohort. The 1-year rate of reoperation and revision were the primary outcomes of this study. Univariate analysis using chisquare tests and student T-tests were performed to analyze any differences in patient demographics, comorbidities, and complications. Multivariate analysis using logistic regression was subsequently conducted to account for any confounding variables and covariates. Results: 9,912 patients underwent TAA without prior hindfoot arthrodesis, 297 patients underwent TAA with prior hindfoot arthrodesis and 174 with hindfoot arthrodesis concurrently with TAA. The incidences of reoperation (OR 3.52, 12.6% vs. 3.9%, P<0.001) and revision (OR 3.66, 4.0% vs. 1.1%, P=0.001) were higher in the simultaneous cohort when compared to the control. However, there were no statistically significant differences in rates of reoperation (OR 0.96, 4.0% vs. 3.9%, P= 0.891) or revision (OR 1.94, 2.4% vs. 1.1 %, P= 0.095) when comparing staged hindfoot arthrodesis to the control. Conclusion: Patients undergoing concurrent hindfoot arthrodesis with TAA had a 3.5 times higher odds of reoperation and revision when compared to the control. Patients undergoing staged procedures did not demonstrate a difference in revision or reoperation rates when compared to the control. Staged hindfoot arthrodesis and TAA may be an effective option in treating complex end-stage ankle and hindfoot arthritis whereas a simultaneous approach may lead to higher rates of complications.

Background: Subtalar distraction arthrodesis is advocated as a salvage procedure for isolated posttraumatic subtalar arthritis. This study aimed at evaluating combined subtalar distraction arthrodesis with peroneus brevis tenotomy for such cases.Methods: Twenty patients with isolated posttraumatic subtalar arthritis managed by combined subtalar distraction arthrodesis and peroneus brevis tenotomy were reviewed for a retrospective study. The American orthopaedic foot and ankle society [AOFAS] hindfoot scoring, talocalcaneal height [TCH], talocalcaneal angle [TCA] and heel valgus angle [HVA] were used for both pre and postoperative assessments.Results: The mean postoperative [TCH] [70.3±1.9mm] was statistically better than the preoperative value [64.7±2.2mm] [p<0.001]. There was a statistically significant decrease in [HVA] [p<0.001]. On the contrary, there was a statistically significant increase in both [AOFAS] hindfoot scoring and the [TCA] [p<0.001].Conclusions: Applying this technique for isolated posttraumatic subtalar arthritis with peroneal tendinitis improved both lateral retromalleolar swelling and deformity correction.

Background: Subtalar distraction arthrodesis (SDA) was developed as a means of treating the symptoms of subtalar arthritis. Despite almost 30 years of research in this field, many controversies still exist regarding SDA. The objective of this study was to present an overview of outcomes following SDA, focusing on surgical technique as well as clinical and radiographic results. Methods: MEDLINE and EMBASE were queried and data abstraction was performed by 2 independent reviewers. Inclusion criteria for the articles were (1) English language, (2) peer-reviewed clinical studies with evidence levels I to IV, (3) with at least 5 patients, and (4) reporting clinical and/or radiographic outcomes of SDA. Results: Twenty-five studies matched the inclusion criteria (2 Level III and 23 Level IV studies) including 492 feet in 467 patients. The most common indication for SDA was late complications of calcaneus fractures. Many different operative techniques have been described, and there is no proven superiority of one method over the other. The most commonly reported complications were nonunion, hardware prominence, wound complications, and sural neuralgia. All studies showed both radiographic and clinical improvement at the last follow-up visit compared with the preoperative evaluation. Pooled results (12 studies, 237 patients) demonstrated improved American Orthopaedic Foot & Ankle Society ankle-hindfoot scores with a weighted average of 33 points of improvement. Conclusion: SDA provides good clinical results at short-term and midterm follow-up, with improvement in ankle function as well as acceptable complication and failure rates. Higher quality studies are necessary to better assess outcomes between different operative techniques. Level of Evidence: Level III. [ABSTRACT FROM AUTHOR]

The aim of this prospective study was to evaluate the results of combined lateral sagittal resection osteotomy with subtalar distraction fusion in heels with painful malunion of the os calcis. This case series included 22 patients (23 feet). The mean age of the patients was 37.52 years. Sixteen (69.6%) patients were initially treated conservatively, 5 (21.7%) patients were treated surgically, and 2 (8.7%) patients were missed. The mean time lapsed before surgery was 11.43 months. A wedge of bone was resected to reduce the width of the malunited os calcis and was used as a local graft for subtalar joint fusion and to increase the height of the os calcis. The mean follow-up period was 56.83 ± 6.09 months. According to the scoring system, satisfactory results were found in 18 (82.6%) patients, and 4 (17.4%) patients had unsatisfactory results. Postoperative radiographic assessment revealed an average increase in the heel height of 7.70 ± 1.22 mm and an average decrease in heel width of 8.39 ± 1.47 mm. The average correction in the coronal axis was approximately 8.04° ± 1.26°. Complications included infection and nonunion in 3 (13%) heels. Two heels still had residual varus postoperatively, and 1 patient had injury to the sural nerve. The restoration of heel height, the reduction in heel width, and the primary fracture pattern had a significant relation with the final score. This method is a successful method for the management of subtalar arthritis caused by malunited calcaneal fractures with broadening leading to lateral abutment. [ABSTRACT FROM AUTHOR]

Arthroscopic subtalar arthrodesis has recently gained popularity in the treatment of primary subtalar or post-traumatic arthritis, coalition, or inflammatory diseases with subtalar arthritis. The present study reports the clinical and radiologic results of 19 patients (19 feet) who underwent posterior arthroscopic subtalar arthrodesis using 2 posterior portals. A total of 19 posterior arthroscopic subtalar arthrodeses (minimum follow-up of 24 months) performed without a bone graft and with 2 parallel screws were prospectively evaluated. The fusion rate was 94% (mean time to fusion 9.8 weeks). Modified American Orthopaedic Foot and Ankle Society ankle-hindfoot scale score (maximum 94 points) improved significantly from 43 to 80 points and the visual analog scale for pain score improved from 7.6 to 1.2. The 12-item short-form physical and mental scores at the last follow-up point were 52.5 and 56.4, respectively. One (5.3%) patient underwent open repeat fusion for nonunion, 2 (10.5%) patients required a second procedure for implant removal, and 1 (5.3%) experienced reversible neuropraxia. In conclusion, posterior arthroscopic subtalar arthrodesis is a safe technique with a good union rate and a small number of complications in patients with no or very little hindfoot deformity.

Background: Subtalar arthrodesis is a common treatment for end-stage subtalar joint arthritis as well as many other clinical problems. The best method of subtalar arthrodesis fixation is unknown. The purpose of this study was to compare the strength of subtalar arthrodesis fixation methods including a single posterior screw (SP), 2 posterior minimally divergent screws (MD) and a 2 screw highly divergent screw (HD) construct for subtalar arthrodesis. Methods: A biomechanical study was performed including the three different screw configurations (SP, MD, HD). These surrogate bone specimens were subjected to applied inversion and eversion torques about the subtalar joint axis on a servo-hydraulic load frame. Torsional stiffness of the construct and the maximum torque for each configuration were measured. Additionally, a cadaver study was performed using 5 fresh-frozen cadaver specimens. The perpendicular distance from the divergent screw guide-wire placement was measured from anatomic structures. Results: The HD screw configuration was found to have the highest torsional stiffness in both inversion and eversion, followed by the MD construct and then the SP construct. Similarly, the HD construct had the highest maximum torque versus the MD and SP constructs. All between-group differences were statistically significant (P < .05). The mean distance from key structures to the divergent screw included the sural nerve (13 mm), peroneus brevis tendon (18 mm), tibialis anterior tendon (8 mm), and tibialis posterior tendon (21 mm). Conclusion: This biomechanical and cadaver study supports the use of 2 screws for fixation of subtalar arthrodesis over a single posterior screw. Additionally, we describe a biomechanically superior and potentially safe, alternative 2-screw divergent construct. Clinical Relevance: This study gives biomechanical support for 2 screw, divergent fixation of subtalar arthrodesis or a single over a single screw or two screw minimally divergent construct.

Objective: To study the variation of different patterns of talar articular facets on the superior surface of calcanei and to highlight its clinical significance. Design: The talar articular facets on the superior surface of adult human calcanei of North indian skeletons have been studied and classified into seven types to know the most common facetal pattern in north indian calcanei as it has clinical significance. Materials and Methods: 194 adult human calcanei of North Indian skeletons have been studied for the different patterns of talar articular facets on the superior surface of calcanei. The calcanei studied have been classified into seven types depending upon number and position of talar articular facets and the criteria laid down by other authors. Results: The most common facetal pattern observed in north indian calcanei is Type 3 (53.61%) followed by Type 5(20.62%). Type 1 and Type 7 have not been observed in the present study. In addition, some unique presentations have been observed in present study. Conclusion: Type 3 is the most common facetal pattern in north Indian calcanei. Orthopaedicians should be aware of the facetal patterns on the superior surface of calcanei while correcting foot deformities like pes palnus and also certain facetal patterns are more predisposed to subtalar joint arthritis.

Background: Tibiotalocalcaneal arthrodesis (TTCA) surgery is indicated for the end-stage disease of the tibiotalar and subtalar joints. Although different fixation technique of TTCA has been proposed to achieve high fusion rate and low complication rate, there is still no consensus upon this point. The purpose of this study is to compare the clinical efficacy of retrograde intramedullary nail fixation (RINF) and locking plate fixation (LPF) for TTCA. Materials and Methods: Fifty four patients who underwent TTCA through the lateral approach with lateral fibular osteotomy using RINF (32 patients, 18 male/14 female, mean age: 48) or LPF (22 patients, 12 male/10 female, mean age: 51) between January 2007 and January 2010 were retrospectively analyzed. Demographic and clinical characteristics, surgery (operation time, blood loss) outcomes (postoperative fusion rates, visual analog scale and foot and ankle surgery score and complications) were compared. Results: The LPF group had a shorter operation time (72.3 ± 9.2 vs. 102.8 ± 11.1 min, P < 0.001), less blood loss (75.9 ± 20.2 vs. 140.0 ± 23.8 ml, P < 0.001) and less intraoperative fluoroscopy sessions (3.6 ± 0.9 vs. 8.4 ± 1.3, P < 0.001) than the RINF group. Patients were followed up for 12-24 months (mean of 16.2 months). Both groups had similar postoperative fusion rates (90.6% and 95.4%) and the LPF group showed a nonsignificant lower complication rate (18.2% vs. 28.1% respectively). Patients at higher risk on nonunion due to rheumatoid diseases may have a lower nonunion rate with LPF than RINF (one out of eight vs. three out of nine, P < 0.001). Conclusions: The LPF for TTCA was simpler to perform compared with RINF, but with similar postoperative outcomes and complication rates. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to evaluate the results of interpositional arthroplasty with tensor fascia lata or fat as a treatment for traumatic subtalar joint arthritis after a fracture of the calcaneus. Methods: From August 2006 to March 2008, 22 patients with traumatic subtalar joint arthritis were enrolled in this study. Tensor fascia lata was implanted for 7 patients who previously underwent surgery with the extensive lateral approach. Fat was implanted for 15 patients who were previously managed with conservative or percutaneous fixation. All the patients were followed up for more than 1 year, and the results were evaluated retrospectively. Results: The Ankle-Hindfoot score by the American Orthopedic Foot & Ankle Society changed from 60.95 to 80.23 ( p < 0.05). Visual Analogue Scale pain score decreased from 6.6 to 3.8 ( p < 0.05). The results of the circle draw test were excellent in 8 patients, good in 11, and fair in 3 patients without any poor outcomes. The subjective satisfaction of the patients was excellent in 16 patients, good in 4 patients, and poor in 2 patients. In 2 patients with poor satisfaction, symptoms and mobility showed no improvement postoperatively. Conclusions: Interpositional arthroplasty with tensor fascia lata or fat as a treatment modality of traumatic subtalar joint arthritis could provide good clinical outcome and preservation of range of motion.

Background:. Consideration of gravity of talar neck fractures and evaluation of the treatment results. Patients and Methods:. 22 patients suffering from talar neck fractures were retrospectively reviewed. There were ten type A, six type B, three type C, and three type D fractures according to the Hawkins classification modified by Canale & Kelly. All patients underwent open reduction and internal fixation. Results:. Excellent clinical results were observed in 45.4%, good in 27.2%, fair in 18.1%, and poor in 9.1% of the patients according to the Iowa Ankle Evaluation score. Two patients developed avascular necrosis (AVN) with body collapse, and tibiotalar fusion was required. Furthermore, five patients developed symptomatic subtalar arthritis but did not require subtalar fusion. Conclusion:. Accurate early open reduction is considered the treatment of choice for such types of fractures. AVN is associated with late management, while subtalar arthritis does not necessarily lead to subtalar fusion. [ABSTRACT FROM AUTHOR]

• Subtalar distraction bone block arthrodesis is commonly employed in the management of calcaneal and talar fracture malunion. • Traditionally it is performed via lateral based approaches, however they have been associated with wound complications. • A novel case and technique illustrating the medial approach for subtalar distraction bone block arthrodesis is presented. Subtalar distraction bone block arthrodesis is a useful technique commonly employed in the management of calcaneal and talar fracture malunion. Traditionally it is performed via a posterolateral or extensile lateral approach, however such approaches have been associated with wound complications, particularly secondary to the added stress caused by the subtalar distraction crucial to this technique. Medial approaches to the subtalar joint have been used in other procedures but have not been reported in subtalar distraction bone block arthrodesis. A novel case and technique illustrating the medial approach for subtalar distraction bone block arthrodesis is discussed. Level 4. [ABSTRACT FROM AUTHOR]

The purpose of this study is to determine the outcomes in TTC fusion when utilizing BMAC as an adjunct., Methods: Twenty consecutive patients who underwent TTC fusion with BMAC adjunct between March 2013 and November 2017 were retrospectively screened for inclusion. Patients were included regardless of comorbidities or risk factors for non-union, and only excluded if they did not have a minimum of 12 months of clinical and/or radiographic chart data. Follow-up was obtained at regular intervals of 6 weeks, 3 months, 6 months and 1 year. Modified RUST scores were applied to grade bony union in a blinded fashion by two orthopedic trauma fellowship-trained surgeons and agreement was assessed via intraclass correlation coefficient (ICC)., Results: Twenty patients were screened and 12 met inclusion criteria for analysis. Majority were male (66.6%) at a mean age of 55.4 years and they were all treated via TTC fusion for a diagnosis of tibiotalar and subtalar arthritis. There were no postoperative complications and no reoperations in this cohort; no donor site morbidity was associated with BMAC. By the 3-month follow-up timepoint, all but one patient received a minimum modified RUST score of 10 indicating bony union (ICC 0.91); by the 6-month time point (ICC 0.94), all 12 patients were deemed united., Conclusion: BMAC as an adjunct in the setting of TTC fusion is a safe treatment option that can promote reliable, consistent bony fusion with minimal complications., Competing Interests: Conflict of InterestOn behalf of all authors, the corresponding author states that there are no conflicts of interest to disclose., (© Indian Orthopaedics Association 2021.)

Post-traumatic osteoarthritis (PTOA) is a complex and painful problem in the foot and ankle. Ninety percent of osteoarthritis cases in the foot and ankle can be classified as post-traumatic. PTOA can affect any of the 33 joints in the foot and the ankle. Distraction arthroplasty is a method for treatment of early arthritic joints without fusing or replacing them and its effectiveness has been well documented. The purpose of this case series is to present our successful experiences and positive results using distraction arthroplasty to treat PTOA in the ankle, subtalar, first metatarsophalangeal, and second tarsometatarsal joints, and to present distraction arthroplasty as a viable alternative to invasive joint sacrificing procedures such as arthrodesis or arthroplasty. Distraction Arthroplasty effectively and safely treats PTOA and improves the stability of joints in the Foot and Ankle. Additionally, the use of bone marrow aspirate concentrate as an adjuvant can improve the long-term functional and structural outcomes of the joint, and can prolong the need for further, more aggressive surgical interventions such as fusion or arthroplasty., Competing Interests: Conflict-of-interest statement: The authors have no conflict of interest to report., (©The Author(s) 2020.

Background: Subtalar arthrodesis is a treatment option for pain due to posttraumatic arthritis following calcaneal fractures. The goal of this study is to examine the results of arthroscopic subtalar arthrodesis for posttraumatic arthritis following calcaneal fractures., Patients and Methods: We performed a retrospective case series reviewing 37 consecutive patients (36 male) treated for posttraumatic arthritis following calcaneal fractures by arthroscopic subtalar arthrodesis. The fractures were due to high-energy injuries in 81% of cases, and 12 fractures (32.4%) had been previously treated with internal fixation. Average follow-up was 57.5 months., Results: Average American Orthopedic Foot and Ankle Society (AOFAS) scores significantly improved from 49.0 ± 10.9 points preoperatively to 76.0 ± 8.0 points at final follow-up. Average time to union was 12.5 weeks. Six patients (16.2%) suffered complications: superficial wound infection (2.7%), symptomatic hardware that warranted removal (5.4%) and nonunion (8.1%) presented nonunion. All three cases had prior internal fixation through an extensile lateral approach, and fused after a repeat surgery., Conclusion: Arthroscopic subtalar arthrodesis offers consistent improvement in cases of posttraumatic arthritis following calcaneal fractures, with a union rate similar to published series of open arthrodesis. We observed more nonunions in patients who had been treated previously with internal fixation. In spite of this, we continue to recommend arthroscopic subtalar arthrodesis, as it preserves the soft tissue envelope better than open techniques., (Copyright © 2018 Elsevier Ltd.

This is a retrospective review of 80 intra-articular calcaneal fractures treated with open reduction and internal fixation by a specialist team under supervision of a single surgeon in a tertiary centre between 2005 and 2014. The fractures were evaluated with plain radiography and computed tomography, and graded using the Eastwood-Atkins classification. A lateral approach was used and all fractures were fixed with calcaneal plates. All patients had clinical and radiological follow-up. Clinical assessment included foot and ankle disability index, SF-36 ® and Kerr-Atkins scores. The mean follow-up duration was 72 months (range: 12-130 months). The mean age of patients was 49 years (range: 17-73 years). There were three open fractures and eight patients had other injuries. The mean Bohler's angle improved from 6° preoperatively to 26° postoperatively. The mean foot and ankle disability index score was 78.62, the mean SF-36 ® scores were 45.5 (physical component) and 52.6 (mental component), and the mean Kerr-Atkins score was 72 (range: 36-100). Early complications included one case of screw protrusion in the subtalar joint (which warranted a repeat procedure), one sural nerve injury and one wound breakdown, which healed with non-operative measures. Twelve patients had symptomatic subtalar joint osteoarthritis. Four of these had subtalar fusion. We believe that our strict protocols of patient selection, intraoperative and postoperative management produced long-term results comparable with those in the peer reviewed literature.

Displaced intraarticular fractures of the calcaneus represent a technically challenging injury. Although there is conflicting evidence regarding advantages and disadvantages of operative versus nonoperative treatment, a growing body of literature suggests operative management with near-anatomic reduction of the posterior facet and restoration of overall calcaneal morphology offers greater potential for superior short- and long-term outcomes. A thorough understanding of calcaneal anatomy, fracture pattern, and associated injuries, along with careful selection of surgical approach and timing to surgery are critical to minimize the risk of complication and maximize potential for optimal outcomes., (Copyright © 2016 Elsevier Inc.
