Osteochondral Lesion of the Talus: Quality of Life, Lesion Site, and Lesion Size.

Osteochondral lesions of the talus (OLTs) are the lesions that affect the articular cartilage and the subchondral bone of the talus. Symptoms develop between 6 and 12 months after the index trauma and are associated with degradation of quality of life. Two-thirds of the lesions (73%) are located on the medial part of the talus, 28% of the lesions are posteromedial, and 31% of the lesions are centromedial. Currently, OLT of up to 100 mm2 can behave in a more indolent condition, and above that area, the defect tends to transmit more shearing forces to adjacent cartilage and is more symptomatic.

Clinical report of microsurgical treatment of Kohler's disease.

The conservative treatment for Kohler's disease will take several months, but some patients still have flatfoot and persistent pain. From October 2013 to July 2015, 3 children with Kohler's disease underwent navicular decompression and micro-circulation reconstruction surgery in our hospital. All the patients have received conservative treatment for more than 3 months and the effect was poor. X-ray showed the bone density of navicular increased significantly. All patients were followed up over 1 year. The 3 patients recovered well. VAS score decreased from 7.0 to 2.6 at 1 month after the operation. The pain symptom disappeared completely on 3 months after surgery. The density of navicular bone recovered to normal. Navicular decompression and micro-circulation reconstruction surgery may quickly improve the ischemic status of navicular bone, alleviate pain symptom and enable patients to resume normal activity as soon as possible.

Treatment of Freiberg's disease using a reverse pedicled metatarsal bone flap: Case report.

Despite no surgical procedures receiving unanimous support for treating Freiberg's disease, several surgical treatment options have been described. For the past few years, bone flaps have been shown in children to present promising regenerative properties. We report a novel technique using a reverse pedicled metatarsal bone flap from the first metatarsal to treat one case of Freiberg's disease in a 13-year-old female. The patient presented 100% involvement of the second metatarsal head, with a 6 × 2 mm defect, unresponsive to 16 months of conservative measures. A 7 mm × 3 mm pedicled metatarsal bone flap (PMBF) was obtained from the lateral proximal first metatarsal metaphysis, mobilized and pedicled distally. It was inserted at the dorsum of the distal metaphysis of the second metacarpal towards the center of the metatarsal head, reaching the subchondral bone. Initial favorable clinical and radiological results were maintained for over 36 months during the last follow-up. Based on the powerful vasculogenic and osteogenic properties of bone flaps, this novel technique could effectively induce bone revascularization and prevent further collapse of the metatarsal's head.

Does AMIC® provide improvements at least two years after surgery for knee osteochondral lesions? A multicentre retrospective study of 101 patients.

BACKGROUND: Osteochondral defects of the knee due to trauma or osteochondritis are associated with osteoarthritis in the medium term. Defects 2 to 8cm2 in size can be managed by autologous matrix-induced chondrogenesis (AMIC®), in which sub-chondral micro-fractures are created within the lesion and the defect is then covered by a matrix of type I and type III collagen to induce de novo cartilage formation. Although promising outcomes have been observed in small single-centre cohorts, the medium-term clinical and radiological effectiveness of AMIC® remains to be demonstrated in larger populations. The objective of this study was to evaluate outcomes of patients at least 2 years after AMIC® for knee osteochondral defects. HYPOTHESIS: AMIC® is associated with clinical and radiological improvements after at least 2 years. MATERIAL AND METHOD: This multicentre (16 centres), multisurgeon (18 senior orthopaedic surgeons), retrospective study included consecutive patients who underwent AMIC® with Chondro-Gide® membrane implantation between September 2011 and January 2020. The 36-item Short Form quality-of-life (SF-36) score, Knee Injury and Osteoarthritis Outcome Score (KOOS), and International Knee Documentation Committee (IKDC) score were determined before the procedure and during follow-up. The Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was assessed by magnetic resonance imaging 2 years after the procedure. RESULTS: In total, 101 patients aged 12 to 60 years were included. Mean follow-up was 30 months. Mean defect size was 3.44cm2 (range, 2-8cm2). Significant improvements were documented in the SF-36 score, KOOS, and IKDC score. The mean MOCART score at 2 years was 75% (range, 20-100). DISCUSSION: The AMIC® procedure was associated with significant improvements at 2.5 years in patients treated for knee osteochondral defects measuring 2 to 8cm2. This method seems to provide similar outcomes to those of other available methods with the advantages of single-step surgery and elimination of osteochondral graft donor-site complications. LEVEL OF EVIDENCE: IV, retrospective observational cohort study.

Successful treatment of advanced Freiberg's disease with a modified Weil osteotomy, 5-year follow up: A Pilot case series with a review of the literature.

INTRODUCTION: Treatment for Freiberg's disease is largely conservative. For severe disease and refractory cases, there are various surgical options. The purpose of this study was to report the 5-year clinical outcomes of a modified Weil osteotomy in the treatment of advanced Freiberg's disease. METHODS: Twelve patients (12 feet), with a mean age of 30.7 years (range 17-55), were treated with synovectomy and modified Weil osteotomy of the affected distal metatarsal head. There were 10 females and 2 males. Clinical outcomes were independently evaluated pre and postoperatively using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and a subjective satisfaction score. Radiological union was evaluated postoperatively. Nine (75%) feet involved the 2nd metatarsal and 3 feet (25%) involved the 3rd metatarsal. According to the Smillie classification, 6 feet were Grade IV and 6 feet were grade V. RESULTS: No patients were lost to follow up and the mean follow-up time was 5.2 years (4-7). AOFAS scores improved from 48.1 + /- 7.4-88.9 + /- 10.1 postoperatively giving a mean improvement of 40.8 (p < 0.001). In total, 92% of patients were satisfied with their operation at latest follow-up, reporting excellent or good results. All patients had postoperative radiological union. One patient had a superficial postoperative infection that was successfully treated with oral antibiotics. CONCLUSION: Modified Weil osteotomy is an effective treatment for advanced Freiberg's disease with good outcomes and few complications.

Effectiveness and safety of arthroscopy combined with radial extracorporeal shockwave therapy for osteochondritis of the talus: a prospective, single-centre, randomized, double-blind study.

Aims: Arthroscopic microfracture is a conventional form of treatment for patients with osteochondritis of the talus, involving an area of < 1.5 cm2. However, some patients have persistent pain and limitation of movement in the early postoperative period. No studies have investigated the combined treatment of microfracture and shortwave treatment in these patients. The aim of this prospective single-centre, randomized, double-blind, placebo-controlled trial was to compare the outcome in patients treated with arthroscopic microfracture combined with radial extracorporeal shockwave therapy (rESWT) and arthroscopic microfracture alone, in patients with ostechondritis of the talus. Methods: Patients were randomly enrolled into two groups. At three weeks postoperatively, the rESWT group was given shockwave treatment, once every other day, for five treatments. In the control group the head of the device which delivered the treatment had no energy output. The two groups were evaluated before surgery and at six weeks and three, six and 12 months postoperatively. The primary outcome measure was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. Secondary outcome measures included a visual analogue scale (VAS) score for pain and the area of bone marrow oedema of the talus as identified on sagittal fat suppression sequence MRI scans. Results: A total of 40 patients were enrolled and randomly divided into the two groups, with 20 in each. There was no statistically significant difference in the baseline characteristics of the groups. No complications, such as wound infection or neurovascular injury, were found during follow-up of 12 months. The mean AOFAS scores in the rESWT group were significantly higher than those in the control group at three, six, and 12 months postoperatively (p < 0.05). The mean VAS pain scores in the rESWT group were also significantly lower than those in the control group at these times (p < 0.05). The mean area of bone marrow oedema in the rESWT group was significantly smaller at six and 12 months than in the control group at these times (p < 0.05). Conclusion: Local shockwave therapy was safe and effective in patients with osteochondiritis of the talus who were treated with a combination of arthroscopic surgery and rESWT. Preliminary results showed that, compared with arthroscopic microfracture alone, those treated with arthroscopic microfracture combined with rESWT had better relief of pain at three months postoperatively and improved weightbearing and motor function of the ankle.

CLINICAL AND IMAGING ASPECTS OF TALAR OSTEOCHONDRITIS: A CASE REPORT FROM GUINEA.

Osteochondral lesions of the dome of the talus are becoming an increasingly frequent problem in sports traumatology, and questioning is a major element in the diagnostic orientation, as these are usually young, athletic patients. The main part of the diagnosis is based on complementary imaging examinations. We report the clinical observation of an adult patient, an athlete, referred to a rheumatology consultation for chronic pain of the right ankle with a mechanical appearance and difficulty in walking. Clinical and paraclinical examinations (standard X-ray, CT scan and magnetic resonance imaging) finally led to the conclusion of an osteochondritis of the talus.

Conceptos actuales en el diagnóstico y tratamiento de las lesiones del hueso subcondral / Current concepts in the diagnosis and treatment of subchondral bone injuries

La patología ósea subcondral incluye una amplia gama de patologías, como la artrosis, las fracturas por insuficiencia espontánea, la osteonecrosis y los traumatismos articulares. Todas muestran hallazgos típicos de imágenes de resonancia magnética (RM) denominados lesiones de la médula ósea (LMO). Sin embargo, la etiología y la evolución de las LMO en múltiples afecciones aún no están claras. Además, todavía no existe un protocolo de tratamiento estándar de oro para las LMO, es por esto que se están probando una variedad de modalidades de tratamiento con la esperanza de que puedan reducir el dolor y detener la progresión de la enfermedad. Nuestro propósito es presentar una revisión sobre los conceptos actuales para el diagnóstico y tratamiento de las LMO. Se realizó una revisión de la literatura que incluyó búsquedas en las bases de datos PubMed, Cochrane y Medline utilizando las siguientes palabras clave: lesiones de médula ósea subcondral, hueso subcondral, subcondroplastia, concentrado de médula ósea, plasma rico en plaquetas (PRP) y aumento óseo subcondral. Podemos concluir que el uso de nuevas técnicas biológicas para tratar las LMO, como el PRP y las células de la médula ósea, ha mostrado resultados clínicos prometedores. La investigación futura de las LMO será necesaria para abordar mejor las diferentes patologías y determinar las estrategias terapéuticas adecuadas. Todavía se necesitan estudios randomizados y controlados de alta calidad junto a revisiones sistemáticas para generar guías y recomendaciones para el tratamiento de las LMO.

Subchondral bone pathology includes a wide range of pathologies, such as osteoarthritis, spontaneous insufficiency fractures, osteonecrosis, and trauma. They show typical magnetic resonance imaging (MRI) findings termed bone marrow lesions (BMLs). However, the etiology and evolution of BMLs in multiple conditions remains unclear. There is still no gold standard treatment protocol in treating BML, and a variety of treatment modalities have been tested in the hope that they might reduce pain and stop disease progression.Our purpose was to write a current concepts review about diagnosis and treatment options for BMLs. A literature review was performed that included searches of PubMed, Cochrane, and Medline databases using the following keywords: Bone marrow lesions, subchondral bone, subchondroplasty, bone marrow concentrate, platelet-rich plasma (PRP), subchondral bone augmentation.The use of novel biologic techniques to treat BMLs, such as PRP and Bone Marrow Cells, has yielded promising clinical outcomes. Future research of BMLs will be mandatory to address the different pathologies better and determining appropriate treatment strategies. There is still a need for high-quality RCTs studies and systematic reviews in the future to enhance further treatment strategy in preventing or treating BMLs of the knee.

[Physical rehabilitation for osteochondrosis of the cervical and thoracic spine in elderly and senile people (Stage 3).]

The concept of a multidisciplinary approach to the treatment of osteochondrosis in elderly and senile patients by specialists of various profiles using medicinal and non-medicinal methods is especially relevant today, therefore, it is necessary to develop and put into practice various options for the combined use of physical rehabilitation means at different stages of rehabilitation treatment of elderly and senile patients with osteochondrosis of the cervical and thoracic spine. The dynamics of clinical manifestations of osteochondrosis after rehabilitation treatment relative to the age of patients in groups showed that the effectiveness of the technique is much higher in elderly patients, in contrast to senile patients and centenarians. The study revealed no significant complications and side effects when using this technique, which allows us to recommend it as a means of secondary prevention of diseases of the cervical and thoracic osteochondrosis, especially in the presence of contraindications to the use of non-steroidal anti-inflammatory drugs and glucocorticoids. The technique can be recommended for use in fitness clubs, athletic halls and medical and physical education dispensaries.

Evaluating Information About Osteochondritis Dissecans Shared Across Social Media Platforms.

BACKGROUND: With the rise of social media, patients are using a variety of online resources to gather information about medical conditions and connect with others for support. Osteochondritis dissecans (OCD) occurs most commonly among children and adolescents, necessitating early diagnosis and management. The purpose of this study is to evaluate content on social media about OCD to quantify the reach of information shared and themes of discussion surrounding this condition. METHODS: A search was performed across Facebook, Instagram, YouTube, and TikTok using the term "osteochondritis dissecans" to identify information shared related to this topic which was then analyzed based on engagement using number of followers, posts, and/or views. RESULTS: Facebook groups provided a forum for online support and information sharing among patients with OCD and their families. The 4 identified groups had a cumulative following of over 4000 people with posts that shared personal recovery stories, solicited treatment advice, and provided updates on patient progress. Review of related Instagram hashtags revealed over 4500 posts, many of which shared personal accounts of living with OCD. The top 5 most viewed YouTube videos collectively had over 189,000 views and were focused on educational information about OCD, relevant surgical techniques, and pertinent anatomy. The top 3 OCD-related TikTok hashtags had over 4 million total views centered on factual knowledge and sharing changes before and after surgical treatment. CONCLUSION: Patients with OCD and their families seek information about their condition and treatment on online sources including social media. Although social media provides a supportive community to share and receive advice, the quality of information shared in these groups is a subject for concern. Increasing physician involvement and awareness of the information shared across social media platforms may improve accuracy of information and content available to patients. CLINICAL RELEVANCE: It is important for physicians treating patients with OCD to be aware of all sources of information and support, including content shared on social media as these platforms allow for the sharing of personal stories, recommendations for treatment, and educational content.

Free vascularised osteochondral flap for the treatment of osteochondritis dissecans of the talus.

We present a case report of a man in his 20s with osteochondritis dissecans of the talus, treated with autologous transplantation of a vascularised osteochondral flap. The patient with high level of activity presented to our orthopaedic outpatient department for progressive limping and pain, mainly related to sports. An osteochondritis dissecans grade IV of the medial talus was identified by MRI. A microvascular transfer of osteochondral tissue was performed successfully. At follow-up 1 year after surgery, the MRI examination revealed vital cartilage; the patient was free of pain and had returned to his previous level of activity.

A new classification for Freiberg's disease.

INTRODUCTION: Freiberg's osteochondrosis is an uncommon cause of foot pain. Following a national survey circulated by the British Foot and Ankle Society it was found that no classification is used to guide surgical treatment. This study aimed to create a simple, reproducible CT based classification to preoperatively plan whether an osteotomy is required. METHODS: A retrospective review of 24 CT scans of new Freiberg's diseasediagnoses over a 10 year period was conducted. These images were assigned a study number and anonymised. The scans were then reviewed in their entirety by three independent specialists who determined whether an osteotomy would be of benefit. The sagittal CT slice that displayed the widest portion of proximal articular margin of the proximal phalanx was identified and divided the articular surface into 2 zones - plantar and dorsal and this formed the basis for our classification. These sagittal slices were then reviewed independently by two surgeons to determine if patients had disease in one or both zones and re-reviewed two weeks later to assess intra-observer reliability. RESULTS: All 24 cases involved the second metatarsal. From reviewing the sagittal CT slices, it was felt that 18 patients were suitable for osteotomy and 6 were suitable for debridement +/- arthroplasty alone. The current classification demonstrated that 18 patients had disease confined to zone 1 only and the remaining patients had disease in both zones. Inter-observer reliability assessment had 95.8% agreement (Krippendorff's Alpha 0.897). Intra-observer reliability was 100%. Correlation of those observed to have isolated zone 1 disease and suitability for osteotomy was absolute (Pearson r = 1). CONCLUSION: Dividing the metatarsal head into two zones on the widest sagittal slice of the CT scan offers an easy reproducible way to preoperatively plan surgical treatment for Freiberg's osteochondrosis. Patients with isolated zone 1 disease should be suitable for an osteotomy.

Clinical and Radiographic Differentiation of Pediatric Patellar Sleeve Fractures and Other Inferior Pole Pathologies.

BACKGROUND: Inferior pole patellar sleeve fractures (PSFs) are rare injuries that occur in skeletally immature patients that may be missed or falsely diagnosed as an inferior pole fracture (IPF) or Sinding-Larsen-Johansson syndrome (SLJS). PURPOSE: The objective of this study was to evaluate and compare clinical and radiographic features of patients with PSF, IPF, and SLJS. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Retrospective review of skeletally immature patients diagnosed with PSF, IPF, and SLJS between 2011 and 2019 at a single urban academic center was performed. Chart and radiographic review was completed. Between-group differences were assessed using analysis of variance, Kruskal-Wallis test, and Fisher exact test, as appropriate to variable distributions. RESULTS: In total, 125 patients (82% male) were included, with a mean (SD) age of 10.7 (2) years (16 PSF, 51 IPF, 58 SLJS). There were no significant differences in patient characteristics between the 3 groups. One hundred percent of the patients with PSF (P < .001) and IPF (P < .001) had acute trauma, compared with 24% of patients with SLJS. Fewer patients with PSF had an intact straight leg raise (38%) compared with those with IPF (94%; P < .001) and SLJS (98%; P < .001). Fewer patients with SLJS had knee swelling (41%) compared with those with PSF (93%; P < .001) and IPF (94%; P < .001). More patients with PSF had knee effusion (81%) compared with those with IPF (37%; P = 0.011) and SLJS (3%; P < .001). More patients with SLJS were able to bear weight (88%) compared with those with IPF (12%; P < .001) and PSF (0; P < .001). Radiographically, compared with those with IPF and SLJS, patients with PSFs had increased mean prepatellar swelling (6.1 [P < .001] and 6.5 [P < .001] vs 12.9 mm), intra-articular effusion (6.1 [P = .014] and 4.9 [P = .001] vs 9.2 mm), maximum fragment size (26 [P = .004] and 17.7 [P < .001] vs 45.3 mm), and maximum fragment displacement (1.24 [P = .002] and 1.45 [P = .003] vs 13.30 mm), respectively. Compared with those with SLJS (1.10), patients with PSF (1.92; P < .001) and IPF (1.22; P < .001) had patella alta with higher mean Insall-Salvati ratios >1.2. CONCLUSION: Differences in clinical features such as ability to straight leg raise, knee swelling, knee effusion, ability to bear weight, and radiographic features, such as prepatellar swelling, intra-articular effusion, fragment displacement/size/shape/location, and patellar height, can all be helpful in recognizing rare pediatric inferior patellar pathology, thus increasing efficiency in indicating for higher-level imaging to reach a prompt diagnosis and provide appropriate treatment.

Description of a Revision Technique for Failed Polyvinyl Alcohol Hydrogel Implant in Patient with Freiberg's Disease.

Polyvinyl alcohol hydrogel synthetic cartilage implants are increasingly used to treat advanced Freiberg disease. We report a case with recurrence of symptoms within 6 weeks and required revision for fracture of the implant. We describe a revision technique with modified osteochondral bone graft to deal with the variables of revision surgery namely: the bone loss, collateral ligament insufficiency, and changes to the proximal phalanx articular surface. We describe a postoperative plan, recovery and a good outcome achieved in 12 month follow-up.

Pediatric Osteochondritis Dissecans of the Talus.

OCDs of the ankle are the third most common lesion in the body and a physician should include this in the differential while evaluating the pediatric population with the history of injury and/or pain in the ankle. Pain, stiffness, and swelling are the most common presenting complaints about the pediatric and adolescent patients with an OCD. Conservative treatment options should be attempted before attempting surgical intervention. Multiple surgical procedures exist to manage the lesion based on location, size, and other factors.

RESUMEN Introducción: el dolor torácico agudo es una sensación dolorosa que se manifiesta entre el diafragma y la base del cuello. En Cuba, constituye una de las causas más frecuentes de consulta médica. La provincia de Matanzas muestra un comportamiento similar. Objetivo: caracterizar el perfil clínico de los pacientes con dolor torácico agudo en la Unidad de Cuidados Intensivos Emergentes, del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas. Materiales y métodos: se realizó un estudio transversal descriptivo con las historias clínicas de 418 pacientes que acudieron a la Unidad de Cuidados Intensivos Emergentes, refiriendo dolor torácico agudo, de enero a diciembre de 2019. Resultados: el rango de edad más afectado fue el de 50 a 59 años, para un 30,38 %. Predominó el sexo masculino con el 30,08 %. El ejercicio físico intenso elevó el riesgo de aparición de dolor torácico. Las primeras causas de dolor torácico agudo fueron, en orden de frecuencia, la osteocondritis esternocostal, la bursitis del hombro y el síndrome coronario agudo. Conclusiones: se evidenció que en la mayoría de los casos el origen del dolor fueron causas no cardiovasculares, afectando más al sexo masculino. Existió asociación estadística significativa entre la actividad física intensa y el inicio del dolor torácico agudo. Egresaron vivos de la unidad el 71,53 % de los pacientes. Se recomienda priorizar la atención de los pacientes que refieren dolor torácico agudo, para una correcta clasificación y atención en el menor tiempo posible (AU).

ABSTRACT Introduction: acute chest pain is a painful sensation perceptible between the diaphragm and the base of the neck. It is one of the most frequent causes of medical consultation in Cuba. It shows a similar behavior in the province of Matanzas. Objective: to characterize the clinical profile of the patients with acute thoracic pain in the Emergency Intensive Care Unit of the Teaching Clinic-Surgical Hospital Comandante Faustino Perez Hernandez, of Matanzas. Materials and methods: a descriptive, cross-sectional study was carried out with the clinical records of 418 patients who attended the Emergency Intensive Care Unit referring acute thoracic pain, from January to December 2019. Results: the most affected age range was the one from 50 to 59 years, for 30.38 %. Male sex predominated, with 30.08 %. Intense physical exercise raised the risk of thoracic pain. The first causes of acute thoracic pain were, in order of frequency, sternocostal osteochondritis, shoulder bursitis, and acute coronary syndrome. Conclusions: It was evidenced that in most of the cases the source of the pain was non-cardiovascular causes, more affecting the male sex. There was significant statistic association between intense physical activity and acute thoracic pain. 71.53 % of the patients was discharged from the unit alive. It is recommended to prioritize the attention of patients referring acute thoracic pain, for their correct classification and care in the shortest possible time (AU).

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

BACKGROUND: Talus 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 PRESENTATION: Here, 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. CONCLUSIONS: Young 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.

Tuberculosis arthritis of the ankle mimicking a talar osteochondritis.

Tuberculosis arthritis of the ankle accounts for 10% of all cases of osteoarticular tuberculosis (OT). Because of its rarity and insidious symptoms, diagnosing it may be challenging. Furthermore, its imaging findings mimic those of other diseases. The case of ankle tuberculosis arthritis misdiagnosed as talus necrosis is reported. The difficulties faced by clinicians when confronting such situations are also illustrated.
