Three-dimensional Mapping Analysis of Talus Fractures and Demonstration of Different Surgical Approaches for Talus Fractures.

The talus is an important component in the ankle, and its treatment after injury is crucial. However, complications and adverse events due to incomplete traditional classifications may still occur, and these classifications fail to analyze the patterns and distribution of fractures from a three-dimensional perspective. Therefore, in this study, we aimed to analyze the location and distribution of fracture lines in different types of talus fractures using three-dimensional (3D) and heat mapping techniques. Additionally, we aimed to determine the surface area of the talus that can be utilized for different approaches of internal fixation, aiding in the planning of surgical procedures. We retrospectively analyzed data from CT scans from 126 patients diagnosed with talus fractures at our two hospitals. We extracted the CT data of a healthy adult and created a standard talus model. We performed 3D reconstruction using patients' CT images and superimposed the fracture model onto the standard model for drawing fracture lines. Subsequently, we converted the fracture lines into a heat map for visualization. Additionally, we measured 20 specimens to determine the boundary for various ligaments attached to the talus. We determined the surface area of the talus available for different surgical approaches by integrating the boundary data with previously reported data on area of exposure. Without considering the displacement distance of the fracture, fracture types were classified as follows, by combining Hawkins and Sneppen classifications: talar neck, 41.3%; posterior talar tubercle, 22.2%; body for the talus and comminuted, 17.5%; lateral talar tubercle, 11.9%; and talar head, 7.1%. We established fracture line and heat maps using this classification. Additionally, we demonstrated the available area for anteromedial, anterolateral, posteromedial, posterolateral, and medial malleolus osteotomy and Chaput osteotomy approaches. Fracture line and heat map analyses can aid surgeons in planning a single or combined surgical approach for the reduction and internal fixation of talus fractures. Demonstrating the different surgical approaches can help surgeons choose the most effective technique for individual cases.

Synthetic bone grafting with preserved cartilage flap via a medial malleolus osteotomy approach to treat osteochondral lesion of the talus: technical note and preliminary clinical results.

Although various surgical procedures are available for osteochondral lesion of the talus (OLT), there is still no consensus on its best treatment. The purposes of this study were to describe a new surgical technique to treat OLT and to analyze its preliminary clinical results. Eight patients were enrolled in this retrospective study between March 2019 and May 2022 in the Second Affiliated Hospital of Chongqing Medical University. All patients were treated by synthetic bone grafting with preserved cartilage flap via a medial malleolus osteotomy approach. The patients' characteristics, operative time, and estimated blood loss were evaluated. Intraoperative photos, preoperative and postoperative X-ray and MRI imaging were recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analog scale (VAS) score were also recorded before surgery and at each follow-up. At six months after the operation, all patients showed bone ingrowth and remodeling according to X-ray and MRI. No obvious defects or ladder was found on the cartilage surface of all patients according to MRI. The AOFAS score improved from 61.63 ± 8.85 (range, 49-74) to 91.13 ± 4.49 (range, 83-97) (p < 0.001) and VAS score improved from 5.50 ± 1.60 (range, 4-8) before surgery to 1.88 ± 0.83 (range, 1-3) (p < 0.001) at latest follow-up. In all eight patients, no wound infection, skin necrosis, or delayed healing of osteotomy was found. We proposed a simple and effective technique that restored the shape of the cartilage surface by preserving the cartilage flap and restoring the natural congruency of the subchondral bone by synthetic bone grafting. We found satisfying clinical outcomes in short-term follow-up. Our new technique might be a new surgical option for the treatment of OLT and its effectiveness should be further evaluated.

Osteochondral lesion of the talus: presentation and management - A case report

Osteochondral lesions of the talus (OLT) involve the chondral and subchondral region typically. Most are secondary to trauma. The patients present with pain, stiffness, swelling. Diagnosis is made typically by clinical and radiological correlation. Treatment strategies employed can be conservative or surgical. This case report is of a 24-year-old male, who presented with pain on the right ankle ,for a chronic period following trauma. The patient was diagnosed with OLT and underwent surgical treatment (Right medial malleolus osteotomy +curettage of right talus + bone grafting + reconstruction of the medial malleolus). This case study is aimed at understanding the various treatment strategies for OLT, both surgical and non-surgical and thus arriving at a conclusion. Treatment of osteochondral lesions is mainly by early screening in high-risk patients (trauma). Although outcomes are favorable in most of the cases, treatment should be individualized to every patient with adequate counseling of outcomes and complications.

Intraosseous Ganglion Cyst of the Talus Treated With Curettage and Bone Grafting Through a Medial Malleolus Osteotomy.

Intraosseous ganglion cyst (IGC) of the talus is a rare entity. There is no consensus regarding the best surgical approach to the talus. In this study, we evaluated the outcomes of curettage and bone grafting of the talus IGC via medial malleolus osteotomy. Seventeen patients with talus IGC who were treated between 2002 and 2020 using curettage and bone grafting through a medial malleolus osteotomy were included. The outcome measures were ankle range of motion (ROM), pain, and function. The ankle pain was evaluated by the visual analog scale (VAS). The ankle function was evaluated by the Toronto extremity salvage score (TESS) and Musculoskeletal Tumor Society (MSTS) score. The study population included 10 men and 7 women with a mean age of 34.9 ± 18.8 years and a mean follow-up of 5.4 ± 3 years. The mean size of the lesion was 2.6 ± 0.8 cm. Postoperatively, mean ankle dorsiflexion and plantar flexion were 19.4 ± 5.8 degrees and 36.7 ± 5.3 degrees, respectively. The mean VAS was 0.9 ± 1.1. The mean MSTS score and TESS were 96.2 ± 3.5 and 94.5 ± 4.1, respectively. Two patients developed ankle osteoarthritis after 3 years (1 stage I and 1 stage II). One of these patients (stage II) also had recurrence after 6 months (recurrence rate: 6.7%). Talus IGC could be adequately managed with curettage and bone grafting through a medial malleolus osteotomy. Even so, mild pain and reduced ankle ROM remain in some patients. Level IV, retrospective cohort study.

To wedge or not to wedge; A cadaveric comparison study of two medial malleolar osteotomy modalities

ObjectiveTo quantify the surface area of the talus accessible with a uniplanar and a biplanar medial malleolus osteotomy. Our secondary purpose study is to quantify the amount of weightbearing area that each osteotomy effects on the tibial articular surface. Patients and methodsEight ankle joint specimens were dissected for this study. The uniplanar osteotomy was performed first. A K-wire marked the limits of access at two different angles: 90° and 30°. The boundaries were marked with a skin marker. Wedges were then created on the tibia plafond, and the osteotomy was converted into a biplanar one. Measurements were repeated again for this osteotomy. The talus, the tibial plafond, and the medial malleolus were then excised. Images were taken and then electronically calibrated for two-dimensional digital measurement of accessible areas. Areas of perpendicular and 30-degree access were recorded for both osteotomies. The articular surface of the tibia was also measured, and an area analysis was performed to calculate the amount of weightbearing cartilage removed by each osteotomy. ResultsAlmost the entire sagittal plane was accessible with both osteotomies. At a 30° angle, bone purchase was achieved for 67.7 % of the talar articular surface with the uniplanar osteotomy and for 74.8 % with the biplanar osteotomy. At a 90° angle, uniplanar osteotomy provided access to 32.7 % of the talar articular area, whereas the biplanar osteotomy achieved an average coverage of 52.8 %. The difference was statistically significant. On average, 25.3 % of the weightbearing area of the tibial plafond is affected when a biplanar osteotomy is performed. ConclusionMedial malleolar osteotomy provides varying degrees of access to the talar dome depending on how it is performed. A wedge-shaped biplanar osteotomy provides greater access and is therefore more suitable for defects located deeper on the talar dome. Despite providing wider access, it results in greater disruption of the weightbearing cartilage of the tibial plafond. Level of evidenceLevel V.

Effect analysis of iliac bone autografting for Hepple V osteochondral lesions of the talus

BackgroundTalar cartilage injury is a kind of disease that causes long-term and chronic pain of ankle joint. Autologous osteochondral transplantation has been viewed as an alternative choice for treating these lesions, but donor-site morbidity has limited its application. This study aimed to analyze the efficacy of iliac bone autografting for Hepple V osteochondral lesions of the talus.MethodsThis retrospective study included 32 patients surgically treated for Hepple V osteochondral lesions of the talus from January 2015 to January 2020. All patients underwent open surgery. Ipsilateral iliac bone grafts were taken and filled with talar cartilage injury area. The improvement of postoperative ankle pain was evaluated by Visual Analogue Scale (VAS), and the improvement of ankle function was evaluated by the American Orthopaedic Foot & Ankle Society (AOFAS). During the postoperative follow-up, X-ray examination of the front and side of the ankle joint and CT of the ankle joint were performed to evaluate the bone cartilage healing in the graft area.ResultsThirty-two patients (32 ankles) (100%) returned for clinical and radiologic follow-up at an average of 28 (range 24–36) months postoperatively. At 3 months postoperatively and at the last follow-up, the AOFAS scores were (80.4 ± 3.6) and (89.2 ± 6.4), respectively, which were significantly improved compared with the preoperative score (49.7 ± 8.1), and the difference was statistically significant (P < 0.05). The VAS scores were (2.1 ± 0.9) and (1.5 ± 0.8), respectively, which were significantly better than the preoperative score (6.2 ± 1.7), and the difference was statistically significant (P < 0.05). Re-examination of the front and side of the ankle joint X-rays and CT showed that the bone healing at the osteotomy of medial malleolus and osteochondral transplantation area. All patients had no pain at the donor site. No complications occurred in 32 patients at the last follow-up.ConclusionsWith iliac bone autografting for Hepple V osteochondral lesions of the talus can effectively relieve ankle joint pain and significantly improved ankle function.Level of evidenceLevel III, Retrospective series.

Coronal Plane Deformity and Total Ankle Replacement: When to Stage with Cement Spacer Ankle Arthroplasty for Deformity Correction

Category:Ankle ArthritisIntroduction/Purpose:Degenerative ankle joint disease is a debilitating condition that causes significant pain, adversely affects function and quality of life. Though primary arthritis of the ankle can occur without deformity, frequently soft tissue imbalances or joint deformities complicate the clinical picture. Often, additional procedures are required to balance the foot and ankle during the index total ankle replacement procedure. When large deformities exist a staged approach to first, align the ankle joint to neutral as stage one and then implantation of the TAR as stage two can be deployed. This paper will further popularize the cement spacer staged TAR technique in correction of coronal deformities, share a clinical algorithm on approach, and depict a case series demonstrating its application.Methods:A case series was performed of 7 patients and 8 ankles, who underwent staged primary TAR utilizing a cement spacer to assist with deformity correction, between the years 2016-2019.Results:Patients' mean age 58.5 yrs., preoperative varus coronal plane deformity mean 19.1 degrees, preoperative valgus coronal plane mean 10.25 degrees. Mean time from stage 1 till 2 was 163.5, +-140.2 days. Stage 1 soft tissue procedures: Chrisman-Snook procedure with synthetic ligament graft, Brostrum-Gould with synthetic graft, Brostrum-Gould without graft, FDL transfer, and isolated medial release/peel. Osteotomies performed during stage one: Dwyer, MDCO, Cotton, and MDCO with medial malleolus osteotomy. Fusions performed during stage one consisted: Subtalar joint, talonavicular joint (TNJ), and STJ with 1st Metatarsophalangeal joint (MTPJ). Seven ankles were replaced with Cadence Total Ankle System (Integra), and one with INBONE II (Wright Medical Technology). Average follow-up time for included patients was 290.75 days (9.7 months). One revision was performed following index TAR procedure.Conclusion:This paper describes a cement wedge spacer staged total ankle arthroplasty technique for correction and stabilization of deforming forces at the ankle joint. While not all ankle deformities necessitate a staged approach, the complexity of the malalignment and the extent of tissue disruption needed to achieve a neutral ankle should be considered when correcting a given deformity with a staged or non-staged approach.

Access to the talar dome through the medial posterolateral approach: an anatomical study.

Background: The osteochondral grafting has become a popular procedure for treating challenging talar dome lesions. However, the vast majority are treated through medial malleolus osteotomy. The aim of this study was to determine the posteromedial area of the talus that can be reached without malleolar osteotomy through the posteromedial approach.&#x0D; Study Design: Descriptive laboratory study. Evidence Level 4&#x0D; Methods: Fifteen human cadaveric ankles were dissected in a standard fashion to expose the posteromedial talar dome. Seven approaches were used on the cadaver's left limb (46.7%). We did not observe any significant difference between the evaluated sides (chi-square test, p = 0.715).&#x0D; Results: On average, 2,09 cm2 (range, 1,72-2,69) of the posteromedial talus dome or 15,27 % (range 12-20) of total talus dome can be accessed without osteotomy.&#x0D; Conclusion: If the osteochondral lesion is within the area accessible through PM approach (mean 2 cm2), as seen on magnetic resonance imaging, it is possible that it can be treated without a medial malleolus osteotomy.&#x0D; Keywords: talus; osteochondral lesions; osteotomy; arthrotomy; surgery

Risk factors for total ankle arthroplasty failure: A Dutch Arthroplasty Register study

BackgroundStudies concerning total ankle arthroplasty could be influenced by several forms of bias. Independent national arthroplasty registries represent objective data on survival and patient reported outcomes. The aim of this study was to determine survival and identify risk factors for early failure in a nationwide series of total ankle arthroplasties from the Dutch Arthroplasty Register (LROI). Patients and methodsData of 810 patients, who received 836 total ankle arthroplasties between 2014 and 2020 were obtained from the Dutch Arthroplasty Register (LROI) with a median follow-up of 38 months (range 1–84 months). Survival was expressed in Kaplan-Meier analysis and associated hazard ratios for implant failure were determined. Implant failure was defined as the need for revision surgery for any reason or (pan)arthrodesis. ResultsDuring follow-up, we recorded 39 failures (4.7%) resulting in a implant survival of 95.3% with a median follow-up of 38 months (range 1–84 months). Medial malleolus osteotomy (HR = 2.27), previous surgery (HR = 1.83), previous osteotomy (HR = 2.82) and previous ligament reconstruction (HR = 2.83) all showed potentially clinically meaningful associations with a higher incidence of implant failure, yet only previous OCD treatment (HR = 6.21), BMI (HR = 1.09) and age (HR = 0.71) were statistically significant. InterpretationExcellent short-term survival (95.3%) with a median follow-up of 38 months was reported for TAA patients from the Dutch Arthroplasty Register. Patients with a lower age, a higher BMI or who had a prior surgical OCD treatment before TAA surgery appear to have a higher risk for revision after short-term clinical follow-up. Thorough patient selection with emphasis on risk factors associated with early implant failure might be essential to improve TAA survivorship.

Gouty tophus as a rare cause of a Hepple stage V osteochondral lesion of the talus

BackgroundTalus osteochondral lesion is commonly associated with trauma, avascular necrosis or even genetic factors, but gouty tophus as a cause of Hepple stage V type talus osteochondral lesion is rare.Case presentationHere, we report a case of an 18-year-old man who complained of left medial deep ankle pain on ambulation. This young man had an extreme liking of sea food rich in purines and also sugar-sweetened drinks. He was diagnosed with a Hepple stage V type talus osteochondral lesion and was treated with medial malleolus osteotomy and an osteochondral graft. The talus osteochondral lesion was found to be a gouty tophus and was completely removed. Hypouricemic therapy was prescribed for 2 months, which allowed the patient to walk with a visual analogue score (VAS) score of 1. He was followed up for 12 months.ConclusionsYoung people with an extreme liking of sea food rich in purines and also sugar-sweetened drinks may be at a risk of developing gout. Acute onset of ankle atraumatic pain, swelling with a high level of serum uric acid and a talus osteochondral lesion with cyst formation should make physicians consider a diagnosis of gout.

Osteochondral Injury of the Talus Treated With Cell-Free Hyaluronic Acid-Based Scaffold (Hyalofast®) - A Reliable Solution.

Background: Osteochondral injuries commonly occur in load-bearing joints, mainly caused by traumatic incidents that can lead to detachment of the cartilage fragment either partial or complete.Objective: This study aims to review the long-term outcome of osteochondral injury of the talus treated with a cell-free hyaluronic acid-based scaffold (Hyalofast®, Anika Therapeutics Inc., Bedford, Massachusetts, USA).Method: This study evaluated the data of seven patients who underwent medial malleolus osteotomy, microfracture, and cell-free hyaluronic acid-based scaffold (HYALOFAST®) insertion between 2015 to 2018. All patients had an osteochondral lesion (OCL) grade III and IV of the talus based on Dipaola classification due to trauma. They were followed up for at least two years and assessed by the short form 36 health survey questionnaire (SF36) for both physical functioning and mental health, American Orthopaedic Foot and Ankle Society (AOFAS) scoring system, and visual analog scale (VAS).Result: All patients were satisfied in terms of physical function, mental health, and pain after one month of surgery (p-value<0.05). There was also an improvement in AOFAS hindfoot and VAS scores from preoperative to postoperative. No complications were noted in the surgical site or bone union.Conclusion: Medial malleolus osteotomy, cell-free hyaluronic acid-based scaffold (HYALOFAST®) grafting, and microfracture are considered relatively easy techniques that are a good choice for patients with sizeable cartilage deficiency and provide a good functional outcome.

Arthroscopic evaluation after osteochondral autogenous transfer with osteotomy of medial malleolus for osteochondral lesion of the talar dome

BackgroundThe purpose of this study was to investigate the second-look arthroscopic evaluation after osteochondral autogenous transfer (OAT) for osteochondral lesion of the talar dome (OLT) with the criteria of the International Cartilage Repair Society (ICRS). MethodsTen patients (twelve ankles) with OLT underwent OAT with osteotomy of the medial malleolus. Clinical outcomes were evaluated using the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale. The condition of the transplanted cartilage was evaluated at the time of second-look arthroscopy using the ICRS Cartilage Repair Assessment. ResultsThe AOFAS ankle-hindfoot scale was significantly improved from 65.1 ± 1.9 points before surgery to 98.1 ± 2.8 points at the time of second-look arthroscopy (p < 0.01). The ICRS Cartilage Repair Assessment was 11.4 points on average (9–12 points). ConclusionsThe OAT for OLT is considered to be a useful treatment even if invasion by medial malleolus osteotomy is added. Level of evidenceLevel IV, Case series.

Intermediate Results of Large Cystic Medial Osteochondral Lesions of the Talus Treated With Osteoperiosteal Cylinder Autografts From the Medial Tibia

To investigate the clinical and radiologic outcomes of an autologous osteoperiosteal cylinder graft from the medial tibia for the treatment of large cystic medial osteochondral lesions (OCLs) of the talus. The study included 15 patients with large cystic medial OCLs. All underwent medial malleolus osteotomy and excision and curettage of the defect site, followed by transplantation with an autologous osteoperiosteal cylinder graft from the medial tibia. They were evaluated preoperatively and after a minimum of 24 months (mean, 44.8 months; range, 24 to 72 months) postoperatively by a visual analog scale, the American Orthopaedic Foot & Ankle Society ankle-hindfoot scale, the Ogilvie-Harris scale, and magnetic resonance imaging of the ankle. The mean visual analog scale score decreased from 5.40 ± 1.06 points to 1.00 ± 1.00 points (P < .001), and the mean American Orthopaedic Foot & Ankle Society score increased from 49.00 ± 8.96 points to 89.00 ± 4.17 points (P < .001). The mean Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was 64.00 ± 5.07 points. According to the Ogilvie-Harris scale, 7 cases were rated as excellent, 5 as good, 3 as fair, and 0 as poor. No complications were observed. An autologous osteoperiosteal cylinder graft from the medial tibia is effective for treating large cystic medial OCLs of the talus and has a low rate of complications. Level IV, case series.

Arthroscopically assisted osteochondral autogenous transplantation for osteochondral lesion of the talus using a transmalleolar approach

Osteochondral autogenous transplantation for osteochondral lesions of the talar dome is usually performed through a miniarthrotomy approach, and a medial malleolus osteotomy approach is selected if the lesion is located posteromedially. Recently, we used a transmalleolar approach without osteotomy of the medial malleolus to perform osteochondral autogenous transplantation for a lesion located in the posteromedial portion of the talar dome. We report on this technique and discuss its advantages, disadvantages, and indications.
