MedCapsNet: A modified Densenet201 model integrated with capsule network for heel disease detection and classification.

Conditions affecting the heel bone, such as heel spurs and sever's disease, pose significant challenges to patients' daily activities. While orthopedic and traumatology doctors rely on foot X-rays for diagnosis, there is a need for more AI-based detection and classification of these conditions. Therefore, this study addresses this need by proposing MedcapsNet, a novel hybrid capsule model combining modified DenseNet201 with a capsule network, designed to accurately detect and classify heel bone diseases utilizing lateral heel x-ray foot images. We conducted a comprehensive series of experiments on the proposed hybrid architecture with several datasets, including the Heel dataset, Breast BreaKHis v1, HAM10000 skin cancer dataset, and Jun Cheng Brain MRI dataset. The first experiment evaluates the proposed model for heel diseases, while the other experiments evaluate the model on a range of medical datasets to demonstrate its performance over existing studies. On the heel dataset, MedCapsNet achieves an accuracy of 96.38%, AUC of 98.35% without data augmentation, cross-validation accuracy of 95.69%, and AUC of 98.87%. The proposed model, despite employing a fixed architecture and hyperparameters, outperformed other models across four distinct datasets, including MRI, X-ray, and microscopic images with various diseases. This is notable because different types of medical image datasets typically require different architectures and hyperparameters to achieve optimal performance.

Insertional Achilles tendinopathy: A radiographic cross-sectional comparison between symptomatic and asymptomatic heel of 71 patients.

Purpose: This retrospective study aimed to investigate whether the standard radiographic indicators for Haglund's syndrome are applicable to insertional Achilles tendinopathy. Methods: Patients who underwent surgery for insertional Achilles tendinopathy in one heel and experienced no pain in the other heel were enrolled in this study. Preoperative calibrated radiographs of the lateral view of the calcaneus were assessed using (1) calcaneal pitch angle, (2) Fowler-Phillip angle, (3) posterior calcaneal angle, (4) Chauveau-Liet angle, (5) X/Y ratio, (6) Haglund's deformity height, (7) Haglund's deformity peak angle, (8) calcification length, (9) calcification width, (10) parallel pitch test, and (11) presence of free body. The Wilcoxon signed rank test and McNemar's test were used for statistical analyses. Results: Seventy-one patients (52 males; mean age, 57.2; mean body mass index, 27.1) were included. Mean values for each index in the symptomatic and asymptomatic heels were as follows, respectively: (1) 23.5, 23.0 (p = 0.30); (2) 58.9, 57.8 (p < 0.05); (3) 7.6, 9.2 (p < 0.05); (4) 15.8, 13.9 (p < 0.05); (5) 2.8, 2.8 (p = 0.87); (6) 5.4, 5.0 (p < 0.05); (7) 99.6, 99.0 (p = 0.44); (8) 10.5, 7.6 (p < 0.001); and (9) 5.1, 4.4 (p < 0.05). The sensitivity, specificity, and area under curve of significant indicators were as follows, respectively: (2) 0.78, 0.37, 0.55; (3) 0.45, 0.72, 0.58; (4) 0.63, 0.54, 0.57; (6) 0.45, 0.69, 0.59; (8) 0.48, 0.80, 0.66; and (9) 0.63, 0.54, 0.59. The presence of free body also showed a significant difference between both heels (p < 0.05). Conclusion: Some radiographic indicators for Haglund's syndrome are applicable to the diagnosis of insertional Achilles tendinopathy. A comparison of the parameters of Haglund's syndrome with those of insertional Achilles tendinopathy may illuminate the etiology and pathology of insertional Achilles tendinopathy and lead to novel treatments.

The Therapeutic Efficacy of Ankle Mobilization and Advance Physiotherapy in Alleviating Heel Spur and Plantar Fasciitis: A Case Report.

Plantar fasciitis arises from progressive damage of the plantar fascia, which originates at the medial calcaneal tuberosity and associated perifascial tissues. The plantar fascia is made up of three segments that grow from the calcaneus and serve a crucial role in appropriate foot biomechanics. The plantar fascia itself is vital in supporting the arch and absorbing trauma. The heel spur is one of the most prevalent causes of foot discomfort. It is important to determine the most effective technique of therapy based on the emergence of pain at each step of the day. This case report describes the thorough rehabilitation of a 42-year-old mesomorphic female, a yoga instructor, and a recreational runner who presented with heel spur and plantar fasciitis symptoms. In addition to traditional therapy, the patient received advanced physical therapy with an emphasis on Mulligan joint mobilization to lessen discomfort and increase range of motion. The objective was to evaluate the effect of this intervention on several outcome measures, such as the visual analogue scale, balance test, foot functional scale, range of motion, and lower extremity functional scale. Targeted exercises and treatments were incorporated into the comprehensive rehabilitation plan to enhance foot function. The patient received the enhanced physiotherapy intervention well. The outcome measure showed notable gains. This case contributes greatly to our knowledge of the best physiotherapy treatments for those with plantar fasciitis and heel spurs.

Comparison of tibial nerve pulsed radiofrequency and intralesional radiofrequency thermocoagulation in the treatment of painful calcaneal spur and plantar fasciitis: a randomized clinical trial.

OBJECTIVE: Ultrasound-guided tibial nerve pulsed radiofrequency (US-guided TN PRF) and fluoroscopy-guided intralesional radiofrequency thermocoagulation (FL-guided intralesional RFT) adjacent to the painful calcaneal spur are two interventions for pain management in painful calcaneal spur and plantar fasciitis. This study aimed to compare the effectiveness of the two procedures. DESIGN: A prospective, randomized, single-blind study. SETTING: Single-center pain clinic. SUBJECTS: Forty-nine patients who met the inclusion criteria were randomized into two groups. METHODS: Group U (25 patients) received US-guided TN PRF at 42°C for 240 s, whereas Group F (24 patients) received FL-guided intralesional RFT at 80°C for 90 s. The most severe numeric rating scale (NRS) score during the first morning steps and the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores were used to evaluate the effectiveness of the procedures. The study's primary outcome assessed treatment effectiveness via the NRS, whereas the secondary outcomes included changes in the AOFAS score and the incidence of procedure-related mild adverse events. RESULTS: NRS and AOFAS scores significantly improved in Groups U and F at 1 and 3 months compared with baseline (P < .05), and there was no significant difference between the groups. At month 1, 50% or greater pain relief was achieved in 72% of patients in Group U and 75% of patients in Group F. No significant difference was observed in the incidence of mild adverse events between the groups. CONCLUSIONS: US-guided TN PRF and FL-guided intralesional RFT have shown significant effectiveness in the treatment of painful calcaneal spur and plantar fasciitis. Larger randomized controlled trials are needed. CLINICAL TRIAL NUMBER: NCT06240507.

Treatment of Plantar Fasciitis in Patients with Calcaneal Spurs: Radiofrequency Thermal Ablation or Extracorporeal Shock Wave Therapy?

BACKGROUND AND OBJECTIVES: We aimed to compare the effectiveness of ESWT (Extracorporeal Shock Wave Therapy) and RFA (Radiofrequency Thermal Ablation) on pain, disability, and activity limitation in the treatment of plantar fasciitis in patients with calcaneal spurs. MATERIALS AND METHODS: Patients who apply to Orthopedics and Traumatology and Physical Medicine and Rehabilitation departments with a complaint of heel pain are included in this retrospective study. We included patients diagnosed with calcaneal spurs who received treatment with ESWT (n = 80) and RFA (n = 79) between 1 August 2021 and 1 September 2022. All patients were evaluated using the Visual Analog Scale (VAS), Foot Function Index (FFI), and the Roles and Maudsley score (RM) before and after treatment. An evaluation was performed on average 6 months after treatment. RESULTS: This study included 79 RFA patients (34 females and 45 males) with a mean age of 55.8 ± 9.6 years and 80 ESWT patients (20 females and 60 males) with a mean age of 49.1 ± 9.5 years. There was a significant decrease in VAS scores after treatment in both the RFA and ESWT groups (z: -4.98, z: -5.18, respectively, p < 0.001). The reductions in FFI pain, FFI activity restriction, FFI disability, and RM scores were significant in both groups, although the scores after treatment were lower in the RFA group. CONCLUSIONS: This study demonstrates that ESWT and RFA significantly reduced pain, disability, and activity restriction in the treatment of plantar fasciitis in patients with calcaneal spurs. ESWT proved particularly effective in alleviating pain, whereas RFA had more pronounced effects on reducing disability and activity limitations. The choice of treatment should be based on the patient's specific complaints.

Clinical, Metabolic, and Radiological Risk Factors in Individuals With Plantar Heel Pain From a South Indian Population: A Cross-Sectional Observational Study.

Background One of the most common conditions seen in an orthopedic outpatient clinic is plantar heel pain (PHP). Studies analyzing various risk factors and their association with the development of PHP have been performed primarily in the Caucasian population, and no study has noted any association between the magnitude of various risk factors and their correlation to the severity of PHP. Hence, we performed a prospective cross-sectional observational study in a select South Indian population presenting with PHP to a tertiary care center. Methods All adult patients presenting to the orthopedic OPD between July 2019 and July 2020 were screened for unilateral PHP and were included after meeting the eligibility criteria. Age, sex, body mass index (BMI), random blood sugar (RBS), uric acid, thyroid-stimulating hormone (TSH), and vitamin D3 were measured as demographic and metabolic parameters. Heel pad thickness, calcaneal spurs, and plantar fascial thickness were noted radiographically. Clinically, the wall-toe distance by weight bear lunge test of each foot was noted, and the severity was measured by the foot functional index (FFI). Results Among the 40 participants, the mean age was 44 (±10.9) years. The average BMI was 30.1 (27.02-32.95). No significant association was noted between the biochemical parameters and the occurrence of PHP. The plantar fascial thickness (PFT) and heel pad thickness (HPT) were thicker than the asymptomatic foot by 1.01 (0.60 - 1.30) mm and 0.79 (0.4-1.7) mm, respectively, which was statistically significant (p<0.001). The heel cord length was found to be reduced by 0.86 (0.6-1) cms, which was statistically significant (p<0.001). The average FFI score was 123.07 (±15.57), and the FFI score percentage in individuals was 53.5% (±6.77). None of the above risk factors showed any significant correlation to the intensity of clinical symptoms measured by FFI (p>0.05). Conclusion Participants had a high BMI and a higher percentage of females. There was a significant increase in PFT and HPT thickness and a significant reduction in gastrocnemius flexibility when compared to the asymptomatic foot. There was no significant association between various clinical, metabolic, and radiological risk factors and the intensity of plantar fasciitis measured by FFI.

Association of Haglund Deformity Size and Insertional Achilles Tendinopathy.

BACKGROUND: We aimed to investigate the effect of Haglund deformity size on insertional Achilles tendinopathy (IAT) using a new measurement system and identify independent risk factors of IAT with Haglund deformity. METHODS: We reviewed medical records of patients with IAT and age/sex-matched patients with diagnoses other than Achilles tendinopathy. Radiographs were reviewed to identify posterior heel spur, plantar heel spur, and intra-Achilles tendon calcification, and to measure Fowler-Philip angle, calcaneal pitch angle, and Haglund deformity angle and height. We introduced a new measurement system for Haglund deformity angle and height and evaluated its intraobserver and interobserver reliability. Multivariate logistic regression analysis was performed to identify independent risk factors of IAT with Haglund deformity. RESULTS: Fifty patients (55 feet) were enrolled in the study group, equaling the size of the age/sex-matched control group. The new Haglund deformity measurement system showed excellent intraobserver and interobserver reliability. No significant differences between the 2 groups were noted in Haglund deformity angle and height: 6.0 degrees in both groups, and 3.3 mm vs 3.2 mm in the study and control group, respectively. The study group had significantly higher calcaneal pitch angle, incidence of posterior heel spur, plantar heel spur, and intra-Achilles tendon calcification: 5.2 vs 23.1 degrees (P = .044), 81.8% vs 36.4% (P < .001), 76.4% vs 34.5% (P = .003), and 67.3% vs 5.5% (P < .001), respectively. Multivariate logistic regression analysis identified independent risk factors of IAT: posterior heel spur (OR = 3.650, 95% CI = 1.063, 12.532), intra-Achilles tendon calcification (OR = 55.671, 95% CI = 11.233, 275.905), and increased calcaneal pitch angle (OR = 6.317). CONCLUSION: Based on our results, the actual size of Haglund deformity as we have reliably measured was not associated with IAT, suggesting a routine Haglund deformity resection may be unnecessary in the surgical treatment of IAT. If patients with Haglund deformity have posterior heel spur, intra-Achilles tendon calcification, or increased calcaneal pitch angle, a higher chance of IAT can be predicted. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Validation of the Foot and Ankle Outcome Score for Use in Infracalcaneal Heel Pain.

There is growing interest in adopting validated and reliable patient-reported outcome measures following surgery. While the Foot and Ankle Outcome Score (FAOS) has previously been validated for use in multiple foot/ankle conditions, it has not yet been validated in patients with infracalcaneal heel pain. In this study we aimed to validate the FAOS by looking at 4 psychometric properties of the survey: construct validity, content validity, reliability, and responsiveness, using patients in our practice with a clinical diagnosis of plantar fasciitis. A total of 150 patients (mean age 49.7 ± 12.1 years [36 men and 114 women]) were included in one or more of the 4 components of this study. All FAOS subscales demonstrated adequate construct validity when compared with the physical health component of the 12-Item Short Form Health Survey (SF-12), and 2 out of 5 subscales demonstrated moderate correlation with the mental health component of SF-12 (all Spearman rho >0.3, and p values <0.05). Most FAOS subscales demonstrated content validity and were found to contain relevant questions from the patient's perspective. All 5 subscales demonstrated good test-retest reliability with intraclass correlation coefficients ≥ 0.827. Finally, 4 out of the 5 subscales (all but other symptoms) were responsive to change at a mean follow up of 12.2 months after surgery (p < .05). We conclude that the FAOS is a responsive, reliable, and valid instrument for use in infracalcaneal heel pain. We believe that due to its ease of use and broad applicability, the FAOS could be more widely adopted in foot/ankle practices as patient-centered healthcare delivery and research becomes increasingly prioritized in the US and abroad.

Comparison of Regenerative Injection Therapy and Conventional Therapy for Proximal Plantar Fasciitis.

Treatment of subacute and chronic heel pain often presents a unique challenge to the physician. Regenerative therapies, such as injectable amnion and connective tissue matrix, may represent a promising new approach in these patients, and have become increasingly popular in the United States. However, little literature exists evaluating these injections compared to conventional nonoperative means. As such, we designed a retrospective comparative study evaluating patients in our practice who received a standardized plantar fascial treatment protocol only (standard therapy), and those who received regenerative plantar fascial injections in addition to standard therapy. A total of 54 patients were followed over a 3-month observation period (91.7 ± 73.9 days), with numeric pain rating (NPR) serving as the primary outcome. Both groups saw an improvement in NPR at the end of the observation period, but patients in the regenerative therapy group demonstrated lower pain scores than those receiving standard therapy alone (mean NPR 2.1 ± 2.3 vs 4.4 ± 2.8, p = .004). Additionally, those in the standard therapy group were significantly more likely to proceed onto surgical intervention compared to the regenerative therapy group (unadjusted odds ratio 15.6, 95% CI 3.0-27.9). The use of regenerative injections for subacute and chronic plantar fasciitis showed promise in our study, and may help mitigate against the need for invasive surgical intervention.

Midterm Outcomes of Endoscopic Plantar Fascia Debridement in 125 Patients: A 5-Year Follow-Up.

Plantar fasciitis is one of the most common pathologies addressed by foot and ankle surgeons. Despite advances and overall success rates for conservative therapy, many of the recalcitrant cases proceed to require surgical correction. Partial to complete release of the fascia is often performed altering foot biomechanics and severing the windlass mechanism. Endoscopic debridement of the plantar fascia allows for direct visualization and removal of the inflammatory tissue while leaving the fascia and its function intact. A total of 125 feet were evaluated with a minimum follow-up time of 5 years. Gender, body mass index, and duration of symptoms were all evaluated and documented. Visual analog scale scores (VAS), American Orthopedic Foot and Ankle Score (AOFAS), and Foot Function Index (FFI) were collected both pre- and postoperatively. AOFAS, FFI, and VAS scores improved from a pre-operative mean of 57.6, 89.4%, and 8.6-89.1, 13.4%, and 0.7 respectively (p < .05) at final follow-up. Of the 125 patients, 98% stated they were satisfied with the operative outcome and would undergo the procedure again. At final follow-up, no patient suffered rupture of the fascia or recurrence. Patients were able to bear weight immediately following the surgery in a walking boot and on average patients were able to return to work at 3.4 days following surgery. This is a novel technique that does not compromise the plantar fascia or alter foot biomechanics with promising 5-year outcomes.

Plantar Fasciitis With a Calcaneal Spur.

This study presents the case of a 47-year-old male with right foot plantar fasciitis and a calcaneal spur. Chronic heel pain can be caused by several medical conditions, including plantar fasciitis and a calcaneal spur, which often may be overlooked on initial evaluation. The risk factors, clinical presentation, imaging findings, and emergency department management of plantar fasciitis with a calcaneal spur are reported and discussed.

Key Considerations When Targeting a Heel Spur.

Heel spur is a common medical condition that can cause substantial discomfort and reduce the quality of life of the affected patients. When seeking treatment for a heel spur, it is important to consider the differential diagnoses and underlying medical conditions that may contribute to the symptoms. This manuscript aims to explore several distinctive diagnostic possibilities, essential factors to consider, and practical strategies for managing heel spurs. This paper explains the common differential diagnoses and addresses medical conditions related to heel spurs. The importance of accurate diagnosis in planning treatment protocol is highlighted. In addition, we explain treatment strategies, including preventive measures, conservative treatments, and more advanced procedures. Physicians can help relieve pain and improve the quality of life of the affected individuals by considering the diverse aspects of managing heel spurs.

[Treatment of Achilles insertional calcific tendinosis using a longitudinal midline incision approach/central tendon splitting approach]. / Therapie der kalzifizierten Insertionstendinopathie der Achillessehne über einen transtendinösen Zugang.

OBJECTIVE: Treatment of Achilles insertional calcific tendinosis through a longitudinal midline incision approach with optional resection of the retrocalcaneal bursa and calcaneal tuberosity (Haglund's deformity). INDICATIONS: Calcific Achilles tendinosis, dorsal heel spur, insertional tendinosis. CONTRAINDICATIONS: General medical contraindications to surgical interventions. Fracture, infection. SURGICAL TECHNIQUE: Longitudinal skin incision medial of the Achilles tendon. Exposure and midline incision of the Achilles tendon with plantar detachment from the insertion site preserving medial and lateral attachment. Resection of a dorsal heel spur and intratendinous calcifications. Optional resection of the retrocalcaneal bursa and calcaneal tuberosity (Haglund's deformity). POSTOPERATIVE MANAGEMENT: Partial weight bearing 20 kg in 30° plantar flexion in a long walker boot for 2 weeks. Afterwards 2 weeks of progressively weight bearing in 15° plantar flexion and another 2 weeks in neutral ankle joint position in a long walker boot. RESULTS: A total of 26 feet of 26 patients with calcific Achilles tendinosis were treated with midline incision of the tendon. In all feet calcific tendon parts were resected. In 10 (38%) feet, a prominent dorsal spur was resected, in 12 feet (38%) retrocalcaneal bursa, and in 24 (92%) feet a calcaneal tuberosity. Mean follow-up was 34.5 months (range 2-64 months). Preoperative Manchester-Oxford Foot Questionnaire (MOXFQ) score was 58.2 (±8.1) and postoperatively the score was 22.75 (±6.0). In all, 7 (26.9%) patients stated delayed wound healing; 1 suffered from deep vein thrombosis. Shoe problems were reported by 50% of patients, and 23.1% suffered from par- or dysesthesia. No revision surgery was required.

Long Term Effectiveness of ESWT in Plantar Fasciitis in Amateur Runners.

BACKGROUND: Shock wave therapy is one of the modern methods of treatment used to treat diseases of muscles, tendons, and entheses in orthopedics, as well as in sports medicine. The therapy is increasingly used in the treatment of plantar fasciitis-a disease that is very difficult and burdensome to treat. Where basic conservative treatment for heel spurs fails, the only alternative consists of excision of the bone outgrowth, and shock wave therapy: a modern, minimally invasive, and relatively safe method. The aim of the study was to determine the long-term effectiveness of extracorporeal shock wave therapy in the treatment of painful ailments occurring in the course of plantar fasciitis in amateur runners. MATERIALS AND METHODS: The study includes a group of 39 men and women, aged 34-64 (mean age 54.05 ± 8.16), suffering from chronic pain in one or both feet, occurring in the course of plantar fasciitis. The patients had to meet five criteria to qualify for the study. The group was divided into two subgroups: those who had not undergone other physiotherapeutic procedures prior to the extracorporeal shock wave therapy (ESWT-alone; 23 people), and those who had received other procedures (ESWT-plus; 16 people). The therapy was performed using extracorporeal shock wave (ESWT). No local anesthesia was used. The effectiveness of the extracorporeal shock wave therapy was evaluated using the visual analogue scale of pain (VAS), Modified Laitinen Pain Index Questionnaire, the AOFAS scale (American Orthopedic Foot and Ankle Society), and a survey questionnaire consisting of 10 questions concerning metrics and subjective assessment of the effects of therapy. The interview was conducted before ESWT, and again five years later. RESULTS: The use of extracorporeal shock wave therapy reduced the intensity and frequency of pain, and improved daily and recreational activity. Moreover, a reduction in the level of pain sensation on the VAS scale and pain symptoms during walking was demonstrated. More favorable results were obtained in the ESWT-plus group; however, the first effects were observed later than in the ESWT-alone group. CONCLUSIONS: Extracorporeal shock wave therapy is an effective form of therapy for amateur runners. It reduces pain associated with plantar fasciitis that amateur runners may experience at rest, while walking, and during daily and recreational activity.

[Surgical treatment of calcifying insertional Achilles tendinopathy via a lateral approach]. / Operative Therapie der kalzifizierenden Insertionstendinopathie der Achillessehne über einen lateralen Zugang.

OBJECTIVE: Reduction of pain and swelling over the Achilles tendon insertion while maintaining function. INDICATIONS: Strong, intolerable pain over the Achilles tendon insertion with chronic, calcifying insertional tendinopathy that does not respond to non-operative treatment over a minimum of 6 months. CONTRAINDICATIONS: Chronic wounds or severe circulatory deficits at the foot or ankle, irradiating or projected pain, complex regional pain syndrome (CRPS). SURGICAL TECHNIQUE: The intratendinous heel spur is resected via a lateral approach. The superior surface of the calcaneal tuberosity is trimmed by resection of the dorsal heel spur with the oscillating saw. A second osteotomy at the medial edge of the tuberosity extends to the insertion of the plantaris tendon. With the third osteotomy, the Haglund deformity is resected. At the resulting area with cancellous bone, the Achilles tendon is reinserted with a suture anchor. POSTOPERATIVE MANAGEMENT: A ventral plastic splint in 20° plantar flexion is worn for a week. Full weight-bearing is allowed in a walking boot with 4 cm heel lift for 6 weeks. The heel lift is then gradually reduced for another 2 weeks. After 8 weeks only an elastic wedge of 1 cm is worn. Physical therapy (isometric exercises) starts in the boot and is intensified after removal of the boot. RESULTS: Seven of 12 patients treated with that technique for calcifying insertional Achilles tendinopathy (58%) stated being pain free according to the Likert scale, while the remaining 5 patients (42%) reported a "substantial improvement". The VISA­A score averaged 84 of 100 points. Postoperative complications have not been observed.

Large variation in participant eligibility criteria used in plantar heel pain research studies - a systematic review.

INTRODUCTION: Variable eligibility criteria across studies on plantar heel pain may result in compromising the generalisability of meta-analyses when heterogeneity is not accounted for. We aimed to explore: (i) heterogeneity of participant eligibility criteria in studies that have investigated plantar heel pain, and (ii) associations between key eligibility criteria and the characteristics of the participants included in the study. METHODS: In this systematic review with narrative synthesis, we extracted participant eligibility criteria, and participants' age, body mass index (BMI), symptom duration and pain level from published studies on plantar heel pain. We performed a content analysis of criteria and aligned overarching criteria to the International Classification of Functioning, Disability and Health (ICF). We pooled studies that used the same thresholds for participant eligibility criteria into sub-groups. We also pooled and reported studies that did not have any eligibility criteria for the quantitative characteristics to use their data for reference values and pooled studies that did not have any eligibility criteria for the characteristics as reference. RESULTS: Two hundred and fourteen articles were included. The most reported participant eligibility criteria (as aligned to the ICF) related to body structures/function and personal factors. Age, BMI, symptom duration and pain level were used with various ranges and/or thresholds across studies (age was reported in 23 different ways across 97 studies; BMI 7/13; symptom duration 14/100; and pain level 8/31). When eligibility criteria included thresholds close to the reference value of a participant characteristic, characteristics were associated with criteria (e.g., younger participants when an upper age threshold was used). CONCLUSION: Participant eligibility criteria in studies on plantar heel pain vary widely; studies differed substantially in their use of quantitative thresholds. Participant characteristics of samples in studies were associated with the criteria used. This study emphasises a need for adjusting for participant heterogeneity in systematic reviews to improve their validity.

The levels of 25-hydroxy vitamin D, parathyroid hormone, calcitonin and lipid profiles in patients with calcaneal spur.

Objectives: The aim of this study was to investigate the 25-hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH), and calcitonin levels and lipid profiles in patients with calcaneal spurs. Patients and methods: Between March 2018 and June 2019, a total of 50 patients (30 males, 20 females; mean age: 39.8±8.1 years; range, 24 to 54 years) admitted to our clinic with heel pain and diagnosed with heel spurs based on radiographic images were included. The control group consisted of 50 age- and sex-matched healthy volunteers (32 males, 18 females; mean age: 35.7±9.6 years; range, 20 to 56 years). Blood samples were collected from all participants. Total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride, phosphate, and calcium levels were measured using the colorimetric method. The PTH and 25(OH)D levels were measured using the chemiluminescent microparticle immunoassay. Calcitonin levels were detected using the chemiluminescent immunometric assay. Results: In the patients with calcaneal spurs, 25(OH)D and HDL-C levels were significantly lower (p<0.001), while LDL-C, triglyceride, and PTH levels were significantly higher (p<0.05, p<0.002 and p<0.001, respectively). There was no significant difference in the calcium, phosphate, body mass index, and calcitonin levels between the groups. Conclusion: Our study results suggest that calcaneal spur formation is associated not only with weight-related pressure, but also with lipid levels and hormonal alterations involved in calcium metabolism. Based on these findings, hormonal alterations and lipids should be considered in patients with calcaneal spurs.

Are models of plantar heel pain suitable for competitive runners? A narrative review.

Background: Plantar heel pain (PHP), or plantar fasciopathy, is a common condition in active and sedentary populations, contributing to short- and long-term reductions in quality of life. The condition's aetiology and pathophysiology are the subjects of a significant body of research. However, much of this research has been conducted with sedentary participants, and comparatively little research exists in a population of highly-trained athletes focused on performance outcomes. Models for PHP and proposed mechanisms, such as high body mass index or systemic disease, are mostly absent from an athletic population. Even less is known about the origins of pain in PHP. Pain is believed to be a complex multifactorial process and may be experienced differently by sedentary and highly active populations, particularly endurance athletes. Consequently, conservative through to surgical treatment for athletes is informed by literature for a different population, potentially hindering treatment outcomes. Aims: The aim of this review, therefore, is to summarise what is known about PHP in athletic populations and propose potential directions for future research. Methods: Embase, PubMed, and Scopus using MeSH search terms for PHP and competitive sport and common synonyms. Discussion: Two explanatory models for PHP were found. These primarily propose mechanical factors for PHP. It remains unclear how gait, body composition, and psychological factors may differ in an athletic population with and without PHP. Therefore, research in these three areas is needed to inform clinical and training interventions for this population.

Quality and readability of online information on plantar fasciitis and calcaneal spur.

Plantar fasciitis and calcaneal spur are common causes of heel pain in the community. People use the Internet to obtain medical information about diseases. We reviewed Internet information sources on plantar fasciitis and calcaneal spur for quality and readability. The first 50 websites for each search term ("calcaneal spur", "heel spur", and "plantar fasciitis") were scanned on www.google.com . Six different valid tools were used for information quality and readability assessment. We searched for HONCode (Health On the Net Foundation Code) stamps on included websites. The total mean points for DISCERN were 50.52 ± 14.62, and the total mean points for JAMA (Journal of the American Medical Association) were 2.42 ± 1.26. In total, 25.72% of 97 websites had HONCode stamps. The average scores for the readability indicators were calculated to be Flesch-Kincaid Grade Level (FKGL): 7.27 ± 1.71, Gunning Fog: 8.46 ± 2.17, Simple Measure of Gobbledygook (SMOG): 6.89 ± 1.24, and Coleman Liau Index: 15.56 ± 1.85. In our study, when the website resources were examined, there were profit websites the most and website quality and readability were moderate level. A significant proportion of the websites have a financial bias and provide low-quality information. A mechanism for monitoring the quality and readability of online information must be established and managed systematically.

68Ga-DOTA-RGD2 Uptake in Plantar Fasciitis: New Insights into its Pathogenesis.

Plantar fasciitis is chronic degenerative tendinopathy of the plantar fascia. Although it has many treatment modalities, none has been very effective due to the largely unknown pathogenesis of this condition. 68Ga-DOTA-RGD2 has an upcoming role in assessing disease activity and treatment response in rheumatoid arthritis. In the present case, we demonstrate the potential role of angiogenesis imaging in understanding the pathogenesis of plantar fasciitis and provide new opportunities for novel imaging options.
