Prevalence of Sonographic Achilles Tendon, Patellar Tendon, and Plantar Fascia Abnormalities in Division I Collegiate Athletes From a Variety of Sports. Clin J Sport Med 2024; 34:297-303. [PMID: 37540559 PMCID: PMC10838354 DOI: 10.1097/jsm.0000000000001183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 06/28/2023] [Indexed: 08/05/2023]
Abstract
OBJECTIVE This study aimed to determine the prevalence of ultrasound abnormalities in the Achilles tendon, patellar tendon, and plantar fascia among a large cohort of collegiate student-athletes. DESIGN Observational cross-sectional study. SETTING Three Division I institutions. PARTICIPANTS 243 student-athletes participated in this study. Exclusion criteria included those younger than 18 years or who underwent prior surgery/amputation of structures, including anterior cruciate ligament (ACL) surgeries with patellar tendon grafts. INTERVENTIONS Ultrasound examination of the Achilles tendon, patellar tendon, and plantar fascia of each leg was performed. An experienced sonographer reviewed each tendon video in a blinded manner, with a separate experienced sonographer separately reviewing to establish inter-rater reliability. MAIN OUTCOME MEASURES The primary outcome measured was the presence of any sonographic abnormality including hypoechogenicity, thickening, or neovascularity. RESULTS Ultrasound abnormalities were identified in 10.1%, 37.2%, and 3.9% of all Achilles tendons, patellar tendons, and plantar fasciae, respectively. Abnormalities were significantly associated with the presence of concurrent pain for all structures ( P < 0.01). Specifically, athletes with sonographic abnormalities were approximately 4 times [relative risk (RR) = 4.25; 95% confidence interval (CI), 2.05-8.84], 6 times (RR = 5.69; 95% CI, 2.31-14.00), and 5 times (RR = 5.17; 95% CI, 1.76-15.25) more likely to self-report pain in the Achilles tendon, patellar tendon, and plantar fascia, respectively. CONCLUSIONS This multi-institutional study completed at 3 Division I institutions is the largest study of its kind to identify the prevalence of sonographic abnormalities in the Achilles tendon, patellar tendon, and plantar fascia among collegiate student-athletes of various sports.

Matsumoto Y, Ogihara N. Direct visualization and measurement of the plantar aponeurosis behavior in foot arch deformation via the windlass mechanism. Clin Anat 2024. [PMID: 38642017 DOI: 10.1002/ca.24171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 03/28/2024] [Accepted: 04/11/2024] [Indexed: 04/22/2024]
Abstract
The plantar aponeurosis (PA) is an elastic longitudinal band that contributes to the generation of a propulsive force in the push-off phase during walking and running through the windlass mechanism. However, the dynamic behavior of the PA remains unclear owing to the lack of direct measurement of the strain it generates. Therefore, this study aimed to visualize and quantify the PA behavior during two distinct foot postures: (i) neutral posture and (ii) windlass posture with midtarsal joint plantarflexion and metatarsophalangeal joint dorsiflexion, using computed tomography scans. Six healthy adult males participated in the experiment, and three-dimensional reconstruction of the PA was conducted to calculate its path length, width, thickness, and cross-sectional area. This study successfully visualized and quantified the morphological changes in the PA induced by the windlass mechanism, providing a precise reference for biomechanical modeling. This study also highlighted the interindividual variability in the PA morphology and stretching patterns. Although the windlass posture was not identical to that observed in the push-off phase during walking, the observed PA behavior provides valuable insights into its mechanics and potential implications for foot disorders.

Abstract
Objective To evaluate the accuracy of musculoskeletal ultrasound measurement of plantar fascia thickness and shear wave elastography (SWE) calculation of Young's modulus in the diagnosis of plantar fasciitis (PFis), and to explore whether it will have any impact on clinical decision-making, rather than just using established diagnostic methods of clinical symptoms and signs. Methods A diagnostic single-center study was conducted in 60 patients with PFis and 64 patients with other types of heel pain. The sensitivity and specificity of musculoskeletal ultrasound in the diagnosis of PFis were calculated according to the diagnostic criteria for PFis recommended by the Clinical Practice Guide for PFis of the American Physical Therapy Association (APTA) Orthopaedic Branch. The analysis of the receiver operating characteristic curve of the subjects was used to study the accuracy of the diagnosis of PFis by two indicators alone and two indicators jointly. Results The thickness of plantar fascia measured by musculoskeletal ultrasound and the area under the curve (AUCs) calculated by shear wave elastography for diagnosing PFis were 0.925 and 0.917, respectively, and the optimal cutoff values were 3.15 mm (sensitivity: 100.0%, specificity: 81.3%) and 63.24 kPa (sensitivity: 78.3%, specificity: 92.2%), respectively. The area under the curve (AUCs) for the combined diagnosis of the two is 0.973 (sensitivity: 93.3%, specificity: 93.8%). Conclusion The thickness of plantar fascia measured by musculoskeletal ultrasound and Young's modulus calculated by SWE have high accuracy in diagnosing PFis, and the combined diagnosis of the two can improve the diagnostic accuracy of patients with PFis.

Abstract
Plantar fasciitis (PF) is a common musculoskeletal disease. Histologic findings of patients with PF showed mainly chronic degenerative processes rather than inflammation. In addition to mechanical factors, such as repetitive stress and reduced ankle dorsiflexion, PF is also linked to rheumatologic diseases and genetic factors. Ultrasound is becoming a standard imaging technique for assessing PF. Major sonographic findings included increased plantar fascia thickness and hypoechoic plantar fascia. In addition to traditional B-mode ultrasound, sonoelastography can also be utilized to diagnose PF. Ultrasound can also be used to guide therapeutic interventions. Over 80% of patients with PF improved under nonsurgical treatment. Treatment options for PF include physical therapy, modalities (laser, therapeutic ultrasound), extracorporeal shock wave therapy (ESWT), injections, transcatheter arterial embolization, and surgery. For injections, corticosteroid was mostly used in the past but has been replaced gradually by other techniques such as platelet-rich plasma or dextrose prolotherapy. There is also more and more evidence about ESWT in treating PF. Surgery serves as an option for recalcitrant PF cases, and endoscopic fasciotomy seemed to have good outcomes. Ultrasound plays an important role in diagnosing of PF and evaluating the treatment effect, and the use of sonoelastography in addition to traditional B-mode ultrasound may help in the early detection of PF and assessment of the treatment effect.

Abstract
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.

Abstract
INTRODUCTION Plantar fasciitis is a debilitating clinical condition and is one of the most common causes of heel pain. The risk factors include frequent and prolonged running, obesity, a sedentary lifestyle, work-related weight bearing, and inappropriate footwear. Ultrasonography being a non-invasive, cost-effective, and easily available modality is a useful adjunct in the diagnosis. METHODS A prospective observational study was conducted among 30 patients with unilateral plantar fasciitis. The diagnosis was based on history and examination. Heel pad thickness and plantar fascia thickness were recorded using ultrasonography. RESULTS The ultrasonography results showed increased plantar fascia and heel pad thickness in the affected limb with plantar fasciitis than the normal one (p<0.001). The BMI was positively correlated with the heel pad thickness (p<0.05). The receiver operating characteristic (ROC) curve showed 90% sensitivity and 60% specificity for heel pad thickness (p<0.001). CONCLUSIONS Ultrasonography is a sensitive and specific tool to identify patients with plantar fasciitis.

Abstract
Best-practice guidelines have incorporated ultrasound in diagnostic and procedural medicine. Due to this demand, the Arizona College of Osteopathic Medicine initiated a comprehensive integration of ultrasound into its first-year anatomy course attended by more than 280 students. Ultrasound workshops were developed to enhance student conceptualization of musculoskeletal (MSK) anatomy through visualizing clinically important anatomical relationships, a simulated lumbar puncture during the back unit, carpal tunnel and shoulder evaluations during the upper limb unit, and plantar fascia, calcaneal tendon, and tarsal tunnel evaluations during the lower limb unit. A 5-point Likert scale survey evaluated if ultrasound improved students' self-perceived anatomical and clinical comprehension of relevant anatomy, improved students' ability to orient to ultrasound imagery, and prompted further independent investigation of the anatomical area. Ultrasound examination questions were added to the anatomy examinations. Two-tailed one-sample t-tests for the back, upper limb, and lower limb units were found to be significant across all Likert survey categories (P < 0.001). Positive student responses to the Likert survey in conjunction with examination question average of 84.3% (±10.3) demonstrated that the ultrasound workshops are beneficial to student education. Ultrasound enhances medical students' clinical and anatomical comprehension and ability to orient to ultrasound imagery for MSK anatomy. This study supports early ultrasound education as a mechanism to encourage students' independent learning as evidenced by many undertaking voluntary investigation of clinical concerns associated with MSK anatomy. This study establishes the successful integration of MSK ultrasound into a large medical school program and its benefit to student clinical education.

Abstract
Background: A plantar fasciotomy using a microdebrider coblation wand may be an effective treatment for treating chronic plantar fasciitis. The objective of this prospective study was to determine the success rate of performing a plantar fasciotomy using a microdebrider coblation wand to treat plantar fasciitis and determine utility of ultrasonographic imaging to evaluate for recovery after treatment. Methods: Patients with plantar fasciitis treated with a plantar fasciotomy using a microdebrider coblation wand were prospectively followed for 1 year. Outcome measures included numeric rating scale (NRS) for pain, Foot and Ankle Disability Index (FADI), the Foot and Ankle Ability Measure for activities of daily living (FAAMA) and for sports (FAAMS), and plantar fascia thickness evaluated with ultrasonographic imaging. Results: Forty patients were included. Average patient age was 53.4 ± 9.9 years. Average symptom duration prior to the procedure was 20 ± 26 months. Five patients dropped out of the study at various points, most due to the COVID quarantine. The mean preoperative NRS score was 4.7 and at 3 and 6 months postprocedure was ≤2. At 1 year, the outcomes were all improved compared to the preoperative status: NRS 0.7±1.3 (P < .001), FADI 107±16 (P < .001), FAAMA 95%±10% (P < .001), FAAMS 84%±19% (P < .001), and plantar fascia thickness 6.8 ± 1.2 mm (P = .014). Furthermore, 86% of patients had clinically successful outcome in pain, defined as NRS score ≤ 2 (95% CI 0, 2), and 91% of patients had a clinically successful outcome in their function, defined as having an FAAMA score ≥75%. There were no complications at the operative site either during or after the procedure. Conclusion: In this study of 40 patients followed prospectively, we found percutaneous plantar fasciotomy using a microdebrider coblation wand to be an effective treatment for plantar fasciitis, with a low incidence of complications. Ultrasonographic imaging may help evaluate for interval healing. Level of Evidence: Level IV, prospective case series.

Abstract
Background Medical imaging can be used to assist with the diagnosis of plantar heel pain. The aim of this study was to synthesise medical imaging features associated with plantar heel pain. Methods This systematic review and meta-analysis conducted searches in MEDLINE, CINAHL, SPORTDiscus, Embase and the Cochrane Library from inception to 12th February 2021. Peer-reviewed articles of cross-sectional observational studies written in English that compared medical imaging findings in adult participants with plantar heel pain to control participants without plantar heel pain were included. Study quality and risk of bias was assessed using the National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies. Sensitivity analyses were conducted where appropriate to account for studies that used unblinded assessors. Results Forty-two studies (2928 participants) were identified and included in analyses. Only 21% of studies were rated ‘good’ on quality assessment. Imaging features associated with plantar heel pain included a thickened plantar fascia (on ultrasound and MRI), abnormalities of the plantar fascia (on ultrasound and MRI), abnormalities of adjacent tissue such as a thickened loaded plantar heel fat pad (on ultrasound), and a plantar calcaneal spur (on x-ray). In addition, there is some evidence from more than one study that there is increased hyperaemia within the fascia (on power Doppler ultrasound) and abnormalities of bone in the calcaneus (increased uptake on technetium-99 m bone scan and bone marrow oedema on MRI). Conclusions People with plantar heel pain are more likely to have a thickened plantar fascia, abnormal plantar fascia tissue, a thicker loaded plantar heel fat pad, and a plantar calcaneal spur. In addition, there is some evidence of hyperaemia within the plantar fascia and abnormalities of the calcaneus. Whilst these medical imaging features may aid with diagnosis, additional high-quality studies investigating medical imaging findings for some of these imaging features would be worthwhile to improve the precision of these findings and determine their clinical relevance.

Abstract
BACKGROUND The use of shear wave elastography (SWE) seems to be an important imaging method in the diagnosis of plantar fasciitis (PF). PURPOSE To compare patients diagnosed with PF with similar and young healthy control groups in terms of B-mode ultrasound (US) and SWE results and to evaluate the elasticity of the plantar fascia. MATERIAL AND METHODS A total of 140 feet of 70 participants were evaluated, including 30 patients and 40 healthy individuals as the control. Clinical, B-mode US, and SWE evaluations were performed for each patient. In addition, American Orthopedic Foot and Ankle Score (AOFAS) was calculated to evaluate pain and foot function in both groups. RESULTS Of the patients in the PF group, 40 (88%) were women and the healthy control groups had similar sex distributions (P = 0.23). The AOFAS score was lower in feet with PF compared to the other groups (P < 0.001). Of 30 patients with PF, 15 (50%) had bilateral PF and 15 (50%) unilateral PF. In addition, ≥4 mm thickness measurement, which was used as a diagnostic criterion for PF as a US finding, could be shown in 11 (73.3%) patients with unilateral PF and 6 (40%) patients with bilateral PF. CONCLUSION In conclusion, the evaluation of the diagnosis of PF with clinical findings and regular follow-up of measurements with SWE can provide measurement results with higher sensitivity in the diagnosis of PF.

Abstract
OBJECTIVE Imaging techniques such as ultrasonography are beneficial for diagnosis of plantar fasciitis. The purpose of this study was to investigate intra-rater reliability of plantar fascia thickness and echogenicity in subjects with and without plantar fasciitis and to compare the measurements between the two groups. DESIGN Sonographic evaluation of the plantar fascia was performed in prone position in 20 subjects without plantar fasciitis and 20 subjects with plantar fasciitis. The outcome measures extracted from the ultrasound images included plantar fascia thickness at the insertion, 1 cm and 3 cm distal from the insertion and plantar fascia echogenicity. The reliability of outcome measures was estimated for both groups using absolute and relative reliability variables. The two groups were compared using analysis of variance (ANOVA). RESULTS ICCs (3, 3) for intra-rater reliability of plantar fascia thickness and echogenicity were, respectively, ≥0.89 and ≥0.89 in the healthy controls and 0.87≥ and 0.90≥ in the plantar fasciitis group. The subjects with plantar fasciitis showed a thicker plantar fascia with lower echogenicity in all of measurement stations of plantar fascia compared to the healthy controls. CONCLUSION The results of the present study indicated that ultrasonography is a reliable method to measure plantar fascia thickness and echogenicity. Furthermore, the findings showed that plantar fascia is affected not only at its insertion but also in other points remote from the insertion in patients with plantar fasciitis. These findings support the diagnostic value of ultrasonography in therapy and research of the patients with plantar fasciitis.

Patience A, Steultjens MP, Hendry GJ. Ultrasound features of Achilles enthesitis in psoriatic arthritis: a systematic review. Rheumatol Adv Pract 2021; 5:ii19-ii34. [PMID: 34755026 PMCID: PMC8570148 DOI: 10.1093/rap/rkab056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Accepted: 07/28/2021] [Indexed: 11/29/2022] Open
Abstract
Objectives The objectives were to evaluate the methodological and reporting quality of ultrasound (US) studies of Achilles enthesitis in people with psoriatic arthritis (PsA), to identify the definitions and scoring systems adopted and to estimate the prevalence of ultrasound features of Achilles enthesitis in this population. Methods A systematic literature review was conducted using the AMED, CINAHL, MEDLINE, ProQuest and Web of Science databases. Eligible studies had to measure US features of Achilles enthesitis in people with PsA. Methodological quality was assessed using a modified Downs and Black Quality Index tool. US protocol reporting was assessed using a checklist informed by the European League Against Rheumatism (EULAR) recommendations for the reporting of US studies in rheumatic and musculoskeletal diseases. Results Fifteen studies were included. One study was scored as high methodological quality, 9 as moderate and 5 as low. Significant heterogeneity was observed in the prevalence, descriptions, scoring of features and quality of US protocol reporting. Prevalence estimates (% of entheses) reported included hypoechogenicity [mean 5.9% (s.d. 0.9)], increased thickness [mean 22.1% (s.d. 12.2)], erosions [mean 3.3% (s.d. 2.5)], calcifications [mean 42.6% (s.d. 15.6)], enthesophytes [mean 41.3% (s.d. 15.6)] and Doppler signal [mean 11.8% (s.d. 10.1)]. Conclusions The review highlighted significant variations in prevalence figures that could potentially be explained by the range of definitions and scoring criteria available, but also due to the inconsistent reporting of US protocols. Uptake of the EULAR recommendations and using the latest definitions and validated scoring criteria would allow for a better understanding of the frequency and severity of individual features of pathology.

Abstract
BACKGROUND The shock-absorbing soft tissues of the heel are composed of dermis and specialized fat pads. Heel fat pad atrophy is common and can be painful and debilitating. In our previous work, autologous fat grafting was effective for treating pain from forefoot fat pad atrophy. OBJECTIVES The authors hypothesized that autologous fat grafting to the heel would relieve pain and improve function in patients with heel fat pad atrophy. METHODS Patients with heel fat pad atrophy and associated pain were recruited and randomized into 2 groups. Group 1 received autologous fat grafting on enrollment and was followed for 2 years. Group 2 received offloading and activity modification for 1 year, then crossed over, underwent autologous fat grafting, and was followed for 1 year afterward. Outcome measures included ultrasound-measured fat pad and dermal thickness; pedobarograph-measured foot pressures and forces; and patient-reported outcomes as measured by the Manchester Foot Pain and Disability Index. RESULTS Thirteen patients met the inclusion criteria and completed the study. Seven (12 affected feet) were randomized into Group 1; and 6 (9 affected feet) were randomized into Group 2. The average age was 55 years and BMI was 30.5 kg/m2. Demographics did not significantly differ between groups. Heel fat pad thickness increased after autologous fat grafting but returned to baseline at 6 months. However, autologous fat grafting increased dermal thickness significantly and also increased fat pad thickness under a compressive load compared with controls at 6 and 12 months. Foot pain, function, and appearance were also significantly improved compared with controls at 6 and 12 months. CONCLUSIONS Autologous fat grafting improved patient-reported foot pain, function, and appearance and may rejuvenate local soft tissues in patients with heel fat pad atrophy. LEVEL OF EVIDENCE: 3

Stretching and relaxing the plantar fascia may change plantar fascia thickness but not pressure pain thresholds: a cross-sectional study of patients with plantar fasciopathy. BMC Musculoskelet Disord 2020; 21:804. [PMID: 33272236 PMCID: PMC7713346 DOI: 10.1186/s12891-020-03833-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Accepted: 11/25/2020] [Indexed: 01/02/2023] Open
Abstract
Background Despite the established relevance of ultrasonography and assessment of pressure pain thresholds in patients with plantar fasciopathy, patient and probe positioning has been mostly ignored and are not necessarily reported in research. The primary aim of this study was to compare plantar fascia thickness in stretched and relaxed positions in patients with plantar fasciopathy. The secondary aim was to compare plantar heel pressure pain thresholds in these positions. Methods In this cross-sectional study, we measured the plantar fascia thickness with ultrasonography, and localised pressure pain thresholds using pressure algometry of 20 patients with plantar fasciopathy. These were assessed bilaterally, with the plantar fascia in both a stretched and relaxed position. In the stretched position, toes were maximally dorsiflexed, while in the relaxed position participants’ feet were hanging freely over the end of the table. Results The plantar fascia of the most symptomatic foot was significantly thicker when stretched compared with the relaxed position (sagittal: mean difference 0.2 mm, 95%CI: 0.1–0.4, P = 0.013; frontal: mean difference − 0.27, 95%CI: − 0.49 to − 0.06, P = 0.014). The plantar fascia was significantly thinner in the frontal plane compared with the sagittal plane in both positions (stretched: mean difference − 0.2 mm, 95%CI: − 0.42 to − 0.03, P = 0.025; relaxed: mean difference − 0.3 mm, 95%CI:-0.49 to − 0.08, P = 0.008). There was no difference between pressure pain thresholds in stretched or relaxed positions in either foot (P > 0.4). Conclusions The plantar fascia was significantly thicker in a stretched compared with a relaxed position and in the sagittal compared with the frontal plane, but differences were smaller than the standard deviation. Pressure pain thresholds were not different between the positions. These results highlight the importance of how ultrasonography is performed and reported in research to allow for replication. Trial registration The study was pre-registered September 25th, 2017 on ClinicalTrials.gov (NCT03291665).

Abstract
The heel pad (HP) which is located below the calcaneus comprises a composition of morphometrical and morphological arrangements of soft tissues that are influenced by factors such as gender, age and obesity. It is well known that HP pain and Achilles tendonitis consist of discomfort, pain and swelling symptoms that usually develop from excessive physical activities such as walking, jumping and running. The purpose of this study was to develop biomechanical techniques to evaluate the function and characteristics of the HP. Ten healthy participants (five males and five females) participated in this laboratory-based study, each performing a two-footed heel raise to mimic the toe-off phase during human locomotion. Twenty-six (3 mm) retroreflective markers were attached to the left and right heels (thirteen markers on each heel). Kinematic data was captured using three-dimensional motion analysis cameras synchronised with force plates. Descriptive and multivariate statistical tests were used in this study. In addition, a biomechanical technique that utilises only six markers from 26 markers to assess HP deformation and function has been developed and used in this study. Overall HP displacement was significantly higher in males on the most lateral part of the right heel (p < 0.05). No significant differences were evident when comparing the non-dominant and dominant heels during the baseline, unloading and loading phases (p > 0.05). Findings from this study suggested that biomechanical outputs expressed as derivatives from tracked HP marker movements can morphologically and morphometrically characterise HP soft tissue deformation changes. The outcome of this study highlights the importance of 3D motion analysis being used as a potential prospective intervention to quantify the function / characteristics of the heel pad soft tissues.

Abstract
Background Extracorporeal shock wave therapy (ESWT) has been used as a safe alternative treatment for refractory musculoskeletal diseases, such as plantar fasciitis, Achilles tendinopathy and gluteal tendinopathy, and various forms of fibromatosis including palmar or penile fibromatosis. However, there is limited published data for clinical and sonographic features of plantar fibromatosis after ESWT. The purpose of this study was to evaluate the long-term clinical outcome of ESWT in ultrasonography-confirmed plantar fibromatosis and ultrasonographic changes of plantar fibroma after ESWT. Methods Medical charts of 26 patients (30 feet) with plantar fibromatosis confirmed by ultrasonography were reviewed. Finally, a total of 10 feet who underwent ESWT for “Poor” or “Fair” grade of Roles-Maudsley Score (RMS) and symptoms persisted for >6 months were included in this study. Short-term follow-up was conducted one week after ESWT and long-term follow-up time averaged 34.0 months. The Numerical Rating Scale (NRS) and RMS were collected for the evaluation of clinical features. Follow-up ultrasonography was conducted at long-term follow-up and changes of plantar fibroma was assessed. A greater than 50% reduction in the NRS and achievement of a “good” or “excellent” grade in the RMS were regarded as treatment success. Additionally, medical charts of 144 patients (168 feet) with plantar fasciitis confirmed by ultrasonography were reviewed and subsequently, 42 feet who underwent ESWT with the same protocol were included for the comparison of clinical features. Results In plantar fibromatosis, baseline NRS (6.2 ± 1.3) and RMS (3.5 ± 0.5) were significantly improved at short-term follow-up (NRS, 1.8 ± 1.0; RMS, 2.0 ± 0.8, P < .001, respectively) and long-term follow-up (NRS, 0.6 ± 1.1; RMS, 1.4 ± 0.8, P < .001, respectively). Treatment success was recorded in seven feet (70.0%) at short-term follow-up and 8 feet (80%) at long-term follow-up, which is comparable to that of the plantar fasciitis group (28 feet, 66.7%; 35 feet, 83.3%, respectively). In long-term follow-up ultrasonography, mean fibroma thickness was reduced from 4.4±1.0 to 2.6±0.8 mm (P = .003); however, length and width were not significantly changed. There were no serious adverse effects. Conclusion While these are preliminary findings, and must be confirmed in a randomized placebo control study, ESWT can have a beneficial long-term effect on pain relief and functional outcomes in painful plantar fibromatosis. However, ESWT is unlikely to affect the ultrasonographic morphology of plantar fibroma, with the exception of reducing the thickness. Level of evidence Level III, retrospective cohort study.

Evaluation of plantar fascia using high-resolution ultrasonography in clinically diagnosed cases of plantar fasciitis. Pol J Radiol 2020; 85:e375-e380. [PMID: 32817771 PMCID: PMC7425221 DOI: 10.5114/pjr.2020.97955] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Accepted: 04/30/2020] [Indexed: 12/22/2022] Open
Abstract
Purpose The aim of this study was to assess the efficacy of high-resolution ultrasonography in the assessment of plantar fascia in individuals with heel pain, before and after treatment. Material and methods This study was conducted from 2016 to 2019, during which time 44 clinically diagnosed patients of plantar fasciitis were compared to 50 normal volunteers. There were 25 males and 25 females in the control group and 42 females and two males in the study group. Thirty-eight patients had unilateral disease, and six patients had bilateral disease. The thickness of the plantar fascia was measured just anterior to its calcaneal attachment using ultrasonography. Body mass index (BMI) was also calculated in both groups. Results The plantar fascia was 2-4 mm thick in the control group whereas it was > 4 mm thick in 48 heels in the study group. With cut-off of > 4 mm as diagnostic of plantar fasciitis, this study had a sensitivity of 96%, specificity of 100%, and accuracy of 98%. BMI was increased in 60% of female patients. All patients were treated with local infiltration of corticosteroid. In 37/42 patients (43 heels) who had improved clinically, the thickness of plantar fascia was reduced to < 4 mm when assessed after six weeks of corticosteroid injection. Conclusions Diagnosis of plantar fasciitis can be easily verified by ultrasonography with plantar fascia thickness > 4 mm being suggestive of plantar fasciitis. Ultrasound can also be used to evaluate treatment response. Ultrasono-graphy helps the clinician in confirming the diagnosis of plantar fasciitis and also in assessing the response to treatment.

Abstract
PURPOSE The aim of this study is to compare elasticity features between patients with plantar fasciitis (PFis) and an asymptomatic healthy control group using shear wave elastography (SWE) and to correlate SWE values with clinical scores. METHODS Consecutive patients diagnosed with PFis and asymptomatic subjects were enrolled in the present study. Both groups underwent clinical, ultrasound (US), and SWE evaluation. A plantar fascia thickness > 4 mm was considered pathognomonic of PFis. SWE stiffness elasticity (Young's modulus in kPa and shear wave velocity in m/s) was measured 1 cm distally from the calcaneal insertion. Correlations with VAS and the 17-Italian Foot Function Index (17-FFI) were determined. RESULTS A total of 19 patients satisfied the inclusion criteria for the patient group and were enrolled in the study, and 21 healthy subjects were used as a control group. Statistically significant differences were found for shear wave velocity between the patient and the control group, with SWE findings of 3.8 (5.1; 1.5) m/s and 4.7 (4.07; 7.04) m/s, respectively (p = 0.006). Strong positive correlations were found between the SWE findings and both the pain and the functional scale (VAS: p = 0.001; FFI: p = 0.012). CONCLUSION SWE allows quantitative assessment of the stiffness of the plantar fascia and can show PFis alterations, increasing the diagnostic performance of B-mode US. In addition, SWE shows a strong correlation with clinical scores, improving patient assessment and follow-up.

Abstract
OBJECTIVE Hyperglycemia leads to increase advanced glycation end products (AGEs) in patients with type 1 and type 2 diabetes. Subsequently, formation of AGEs can cause increased plantar fascial thickness (PFT), an imaging feature of plantar fasciitis (PF). This study evaluates the prevalence of PF in a contemporary cohort of type 1 diabetes and type 2 diabetes patients managed according to current standards, compared to patients without diabetes. RESEARCH DESIGN AND METHODS This is a five-year prevalence study in a large tertiary health system (approximately 535,000 patients/visits/year) with a single electronic medical record (EMR), applying a cohort discovery tool and database screen (Data Direct) with use of ICD-9 and ICD-10 codes. All patients with a PF diagnosis between 01/01/2011 and 01/01/2016 were included and divided into 3 groups: type 1 diabetes (7148 patients), type 2 diabetes (61,632 patients), and no diabetes (653,659 patients). Prevalence rates were calculated, accounting for other risk factors including BMI and gender using Fisher's exact test. RESULTS The overall prevalence of PF in the entire study population was 0.85%. Prevalence rates were higher in patients with diabetes, particularly with type 2 diabetes (42% and 64% higher compared with patients with type 1 diabetes and no diabetes respectively). Individually, PF rates were 0.92% in type 1 diabetes and 1.31% in type 2 diabetes compared with 0.80% in patients with no diabetes (Type 1 vs. no diabetes p = 0.26; Type 2 vs. no diabetes p ≪ 0.0001; Type 1 vs. Type 2 diabetes p = 0.0054). Females in all groups had higher prevalence of PF than males (p ≪ 0.0001 for all), with those patients with diabetes having higher prevalence rates than those without diabetes. Patients with higher BMI levels (BMI ≥ 30 kg/m2) were also more likely to have PF in all categories except males with type 1 diabetes (p = 0.40). CONCLUSIONS In this large contemporary population managed in a tertiary health system, prevalence rates of PF were substantially higher in patients with diabetes compared with no diabetes, particularly in type 2 diabetes. Female gender and higher BMI were also associated with higher prevalence of PF in this cohort.

Abstract
Background: Intense therapeutic ultrasound (ITU) is an innovative ultrasound-based therapy where sound waves are concentrated into select musculoskeletal tissue. These focused waves generate thermal coagula at a controlled depth and space while preserving surrounding tissues. A multicenter study was conducted evaluating the efficiency, safety, and patient tolerance of ITU for the treatment of chronic plantar fasciitis (CPF) pain. Methods: Seventy-four CPF patients, having failed conservative and/or minimally invasive treatment, participated in the study. Randomized participants either received 2 ITU treatments or 2 sham ITU treatments in addition to standard-of-care therapy. Plantar fascia pain was assessed pretreatment and at 4, 8, 12, and 26 weeks after treatment. Diagnostic ultrasonographic images were analyzed to examine hypoechoic, perifascial lesions whose volumes were calculated until week 12. Function and patient satisfaction were measured using self-reported outcome measures. Results: The treated group reported significant average pain reduction (–26%, –33%, –43%) and hypoechoic lesion volume (–33%, –53%, –68%) at weeks 4, 8, and 12 compared to baseline. Although the control/sham group reported insignificant pain changes at the same time points (–5%, +8%, and +2%) and increased hypoechoic lesion volume (+15%, +28%, +58%). Treated patients reported a significant increase in daily living activities (+28%, +42%, +47%, +40%) compared to the sham/control group (+0.12%, +12%, +3%, +21%). Patient satisfaction remained more than 80% at weeks 8, 12, and 26 for all treatment groups. Conclusion: ITU is an effective pain relief treatment for CPF, which is refractory to either conservative measures or minimally invasive treatments. Level of Evidence: Level II.

Abstract
Intense therapeutic ultrasound for chronic plantar fasciitis musculoskeletal tissue pain reduction was evaluated in a pivotal clinical trial examining effectiveness, safety, and patient tolerance. In this single-blinded study, 33 patients received 2 treatments that were 4 weeks apart on plantar fascia tissue along with conservative standard of care. Patients were followed for up to 6 months after the first treatment, receiving a physical examination and diagnostic ultrasound at each follow-up visit and completing patient-/subject-reported outcome measure and Foot Function Index surveys. The goal was to reduce overall pain by ≥25% on average and >25% individually. Hypoechoic area changes on diagnostic ultrasound and adverse events were measured. The percentage meeting pain reduction criteria at weeks 4, 8, 12, and 26 were 72%, 81%, 86%, and 79%, respectively. Mean pain scores at each visit were significantly different from baseline (p < .001) at -39%, -49%, -51%, and -44%. Hypoechoic lesions were found in all patients and decreased in size significantly (p < .05) at weeks 8 and 12 (-56% and -67%). Foot Function Index scores declined favorably from baseline (p < .001) at all time points (-32%, -46%, -49%, and -32%). The percentages of patients meeting satisfaction criteria were 72%, 85%, 90%, and 83%. The mean pain score during treatment 1 was 3.4, and during treatment 2, 2.9. Attrition of only 1 patient owing to pain occurred, after treatment 1. No adverse events occurred. Intense therapeutic ultrasound for chronic plantar fasciitis is shown to be effective, safe, and well tolerated in this pivotal clinical trial.

Abstract
BACKGROUND: Ultrasound is a widely used diagnostic tool for patients with plantar fasciitis. However, the lack of standardization during the measurement for plantar fascia thickness has made it challenging to understand the etiology of plantar fasciitis, as well as identify risk factors, such as gender. The purpose of this study was to investigate gender differences regarding plantar fascia thickness while controlling for metatarsophalangeal (MTP) joint position in the healthy and those with unilateral plantar fasciitis. METHODS: Forty participants (20 with unilateral plantar fasciitis and 20 controls) with plantar fascia thickness (mean age, 44.8 ± 12.2 years) participated in this study. The majority were females (n = 26, 65%). Plantar fascia thickness was measured via ultrasound 3 times at 3 different MTP joint positions: (1) at rest, (2) at 30 degrees of extension, and (3) at maximal extension. RESULTS: When comparing gender differences, the males in the plantar fasciitis group had a significantly thicker plantar fascia than the females ( P = .048, η2 = 2.35). However, no significant differences were observed between healthy males and females. The males with unilateral plantar fasciitis also had significantly thicker asymptomatic plantar fasciae collectively compared with controls ( P < .05), whereas females with unilateral plantar fasciitis had a similar but not significant change. CONCLUSION: It appears that healthy males and females have similar plantar fascia thickness. However, as plantar fasciitis develops, males tend to develop thicker plantar fasciae than their female counterparts, which could have future treatment implications. LEVEL OF EVIDENCE: Level III, case-control comparative study.

Abstract
OBJECTIVE The aim of this study was to define a quantitative parameter to indicate which cases of plantar fasciitis will benefit from local corticosteroid injection or ESWT and to compare the efficacy of two different treatment modalities. METHODS Seventy patients (mean age: 49.10; range: 41-58) with chronic plantar fasciitis unresponsive to conservative treatment for 3 months were treated with either betamethasone injection or extracorporeal shock wave therapy (ESWT). Correlation between AOFAS scores, fascia thickness, duration of symptoms, age and calcaneal spur length were assessed. RESULTS Degree of fascial thickening (mean 4.6 mm for all patients) did not influence baseline AOFAS scores (r = -0.054). Plantar fascia thickness significantly decreased in both groups after treatment (1.2 mm for steroid, 1.2 mm for ESWT) (p < 0.01 for both groups). Percentage of change in AOFAS scores (68% for steroid and 79% for ESWT, p = 0.069) and fascial thickness (24% for steroid and 26% for ESWT, p = 0.344) were similar between two groups. Functional recovery was not correlated with baseline fascial thickness (r = 0.047) or degree of fascial thinning after treatment (r = -0.099). Percentage of change in AOFAS scores was correlated only with baseline AOFAS scores (r = -0.943). CONCLUSIONS Plantar fascia thickness increases significantly in plantar fasciitis and responds to treatment. Both ESWT and betamethasone injection are effective in alleviating symptoms and reducing plantar fascia thickness in chronic plantar fasciitis. However, the only predictive factor for functional recovery in terms of AOFAS scores is patients' functional status prior to treatment. Measuring of plantar fascia is not helpful as a diagnostic or prognostic tool and MRI imaging should be reserved for differential diagnosis. LEVEL OF EVIDENCE Level III, Therapeutic study.

Abstract
BACKGROUND We compared diagnostic ultrasound images of the plantar fascia with available patient histories for symptomatic patients previously diagnosed as having plantar fasciitis. Plantar fascia thickness and depth, the prevalence of perifascial hypoechoic lesions, and injury timelines in patients were reviewed. METHODS Images and histories for 126 symptomatic patients were collected from a patient database. We documented plantar fascia depth and thickness and the visualization of hypoechoic perifascial lesions. After image analysis, the obtained plantar fascia thickness measurements were compared with various patient attributes for possible relationships, including age, weight, and body mass index. In addition, plantar fascia thickness measurements were separated based on injury timeline as well as symptomatic/asymptomatic foot for patients with unilateral conditions to check for significant differences between subgroups. These were, in turn, compared with a control group of 71 individuals with no heel pain or diagnosis of plantar fasciitis. RESULTS Overall, mean ± SD symptomatic thickness (n = 148) was 6.53 ± 1.56 mm. Mean ± SD symptomatic depth (n = 136) was 13.36 ± 2.14 mm. For the control group, mean ± SD thickness was 3.20 ± 0.66 mm and depth was 10.30 ± 2.00 mm. Comparison of thickness based on injury timeline showed two significant differences: acute injuries (≤3 months) are significantly thicker than chronic injuries (>3 months), and only acute symptomatic thicknesses are significantly different from their asymptomatic thickness counterparts. Age, weight, and body mass index did not show significant correlations to thickness. Analysis of ultrasound images showed that 93% of symptomatic feet had hypoechoic lesions. CONCLUSIONS Injury timeline and the presence of hypoechoic lesions may play important roles in patient discomfort, diagnosis, and treatment of plantar fasciitis.

Abstract
Background Ultrasound is an inexpensive method for quantifying plantar fascia thickness, especially in those with plantar fasciitis. Ultrasound has also been used to assess the effectiveness of various treatments for plantar fasciitis by comparing plantar fascia thickness before and after an intervention period. While a plantar fascia thickness over 4 mm via ultrasound has been proposed to be consistent with plantar fasciitis, some researchers believe the 4 mm plantar fascia thickness level to be a dubious guideline for diagnosing plantar fasciitis due to the lack of standardization of the measurement process for plantar fascia thickness. In particular, no universal guidelines exist on the positioning of the metatarsophalangeal (MTP) joints during the procedure and the literature also has inconsistent protocols. The purpose of this study is to investigate and compare the influence of MTP joint extension on plantar fascia thickness in healthy participants and those with unilateral plantar fasciitis. Methods The plantar fascia thickness of forty participants (20 with unilateral plantar fasciitis and 20 control) was measured via ultrasound three times at three different MTP joint positions: 1) at rest, 2) 30° of extension from the plantar surface, and 3) maximal extension possible. Results The plantar fascia became significantly thinner as MTP joint extension increased in both the plantar fasciitis group (p < 0.001) and the control group (p < 0.001). In the plantar fasciitis group, the involved plantar fascia was 1.2 to 1.3 mm thicker (p < 0.001) than the uninvolved side depending on the MTP joint position. In the control group, the difference in plantar fascia thickness between the two sides was less than 0.1 mm (p < 0.92) at any MTP joint position. Conclusions MTP joint position can influence the ultrasound measurement of plantar fascia thickness. It is recommended that plantar fascia thickness measurements be performed with the toes at rest. If MTP joints must be extended, then the toes should be extended maximally and then noted to ensure subsequent ultrasound procedures are repeated. Standardizing the position of the MTP joints is not only important for attaining the most accurate thickness measurement of the plantar fascia, but is also important to researchers who use plantar fascia thickness to determine the effectiveness of various plantar fasciitis interventions.

Abstract
BACKGROUND We compared the long-term clinical and ultrasonographic effects of radial extracorporeal shockwave therapy (rESWT) versus ultrasound-guided corticosteroid injection treatment in patients with plantar fasciitis unresponsive to conservative therapy. METHODS Seventy-two patients with unilateral plantar fasciitis were randomized to receive either rESWT (three times once per week) (n = 36) or corticosteroid treatment (a single 1-mL dose of betamethasone sodium plus 0.5 mL of prilocaine under ultrasound guidance by injection into the plantar fascia) (n = 36). The primary outcome measures were visual analog scale (VAS) and Foot Function Index (FFI) scores. Secondary outcome measures included the heel tenderness index (HTI) score and plantar fascia thickness (PFT) as obtained by ultrasound examination. All of the assessments were performed at baseline and 1, 3, and 6 months after treatment. RESULTS Significant improvements were observed in the rESWT group in VAS, HTI, and FFI scores and PFT at the end of treatment and were maintained during follow-up. Posttreatment improvements in VAS, HTI, and FFI scores and PFT were also seen in the corticosteroid group but were not maintained for VAS and FFI scores after the completion of therapy and were lost at 1 and 6 months, respectively. No serious treatment-related complications occurred. CONCLUSIONS Both rESWT and corticosteroid injection therapy are effective modalities for treatment of chronic plantar fasciitis. However, rESWT seems to be superior to corticosteroid injection therapy due to its longer duration of action.

Abstract
Plantar fascia (PF) disorders commonly cause heel pain and disability in the general population. Imaging is often required to confirm diagnosis. This review article aims to provide simple and systematic guidelines for imaging assessment of PF disease, focussing on key findings detectable on plain radiography, ultrasound and magnetic resonance imaging (MRI). Sonographic characteristics of plantar fasciitis include PF thickening, loss of fibrillar structure, perifascial collections, calcifications and hyperaemia on Doppler imaging. Thickening and signal changes in the PF as well as oedema of adjacent soft tissues and bone marrow can be assessed on MRI. Radiographic findings of plantar fasciitis include PF thickening, cortical irregularities and abnormalities in the fat pad located deep below the PF. Plantar fibromatosis appears as well-demarcated, nodular thickenings that are iso-hypoechoic on ultrasound and show low-signal intensity on MRI. PF tears present with partial or complete fibre interruption on both ultrasound and MRI. Imaging description of further PF disorders, including xanthoma, diabetic fascial disease, foreign-body reactions and plantar infections, is detailed in the main text. Ultrasound and MRI should be considered as first- and second-line modalities for assessment of PF disorders, respectively. Indirect findings of PF disease can be ruled out on plain radiography. Teaching Points • PF disorders commonly cause heel pain and disability in the general population. • Imaging is often required to confirm diagnosis or reveal concomitant injuries. • Ultrasound and MRI respectively represent the first- and second-line modalities for diagnosis. • Indirect findings of PF disease can be ruled out on plain radiography.

Abstract
BACKGROUND Heel pain is a prevalent concern in orthopedic clinics, and there are numerous pathologic abnormalities that can cause heel pain. Plantar fasciitis is the most common cause of heel pain, and the plantar fascia thickens in this process. It has been found that thickening to greater than 4 mm in ultrasonographic measurements can be accepted as meaningful in diagnoses. Herein, we aimed to measure normal plantar fascia thickness in adults using ultrasonography. METHODS We used ultrasonography to measure the plantar fascia thickness of 156 healthy adults in both feet between April 1, 2011, and June 30, 2011. These adults had no previous heel pain. The 156 participants comprised 88 women (56.4%) and 68 men (43.6%) (mean age, 37.9 years; range, 18-65 years). The weight, height, and body mass index of the participants were recorded, and statistical analyses were conducted. RESULTS The mean ± SD (range) plantar fascia thickness measurements for subgroups of the sample were as follows: 3.284 ± 0.56 mm (2.4-5.1 mm) for male right feet, 3.3 ± 0.55 mm (2.5-5.0 mm) for male left feet, 2.842 ± 0.42 mm (1.8-4.1 mm) for female right feet, and 2.8 ± 0.44 mm (1.8-4.3 mm) for female left feet. The overall mean ± SD (range) thickness for the right foot was 3.035 ± 0.53 mm (1.8-5.1 mm) and for the left foot was 3.053 ± 0.54 mm (1.8-5.0 mm). There was a statistically significant and positive correlation between plantar fascia thickness and participant age, weight, height, and body mass index. CONCLUSIONS The plantar fascia thickness of adults without heel pain was measured to be less than 4 mm in most participants (~92%). There was no statistically significant difference between the thickness of the right and left foot plantar fascia.

Abstract
BACKGROUND Musculoskeletal ultrasound is a non-invasive and low-cost modality for real-time visualisation of the plantar fascia. Ultrasound examination for plantar fasciitis is generally performed with the patient in a prone position, although the rational for using a prone position has not been validated. The aim of the study was to investigate if ultrasound examination in a supine position, which is more comfortable than the prone position, is valid. METHODS We conducted a prospective study of 30 participants with plantar fasciitis, 8 men (27 %) and 22 women (73 %), with a mean age of 53.9 ± 12.6 (range, 32 to 77) years, and an equal distribution of left and right feet. The plantar heel was divided into three portions for ultrasound examination: medial, central and lateral. Two measurements of plantar fascia thickness were obtained for each portion, with participants in 2 positions (supine and prone) and for 2 ankle postures (neutral and 15° of plantarflexion). Mean measurements of plantar fascia thickness were compared between the two positions (Wilcoxon signed rank tests for non-normally distributed data and paired t-tests for normally distributed data). Participants were asked to report their preferred position for examination, supine or prone. RESULTS The measured thickness was comparable for both supine and prone positions, for both ankle postures, neutral and 15° of plantarflexion (p > 0.05). A specific self-reported preferred position was not identified. CONCLUSIONS Ultrasound examination of plantar fasciitis can be performed in the supine position without any significant difference in measurement compared to examination in the conventional prone position. TRIAL REGISTRATION The Catholic Medical Center Office of Human Research Protection Program (CMC-OHRP)/Institutional Review Board approved the current study (Approval No. KC12DISI0338), and all participants provided their written informed consent for participation and publication.

Abstract
OBJECTIVE To investigate plantar fascia elasticity in patients with typical clinical manifestations of plantar fasciitis but normal plantar fascia morphology on B-mode sonography. MATERIALS AND METHODS Twenty patients with plantar fasciitis (10 unilateral and 10 bilateral) and 30 healthy volunteers, all with normal plantar fascia morphology on B-mode sonography, were included in the study. Plantar fascia elasticity was evaluated by sonoelastographic examination. All sonoelastograms were quantitatively analyzed, and less red pixel intensity was representative of softer tissue. Pixel intensity was compared among unilateral plantar fasciitis patients, bilateral plantar fasciitis patients, and healthy volunteers by one-way ANOVA. A post hoc Scheffé's test was used to identify where the differences occurred. RESULTS Compared to healthy participants (red pixel intensity: 146.9 ± 9.1), there was significantly less red pixel intensity in the asymptomatic sides of unilateral plantar fasciitis (140.4 ± 7.3, p = 0.01), symptomatic sides of unilateral plantar fasciitis (127.1 ± 7.4, p < 0.001), and both sides of bilateral plantar fasciitis (129.4 ± 7.5, p < 0.001). There were no significant differences in plantar fascia thickness or green or blue pixel intensity among these groups. CONCLUSION Sonoelastography revealed that the plantar fascia is softer in patients with typical clinical manifestations of plantar fasciitis, even if they exhibit no abnormalities on B-mode sonography.

Abstract
OBJECTIVES The primary objective of this study was to determine whether the sonographic appearance of the plantar fascia is predictive of the treatment (ie, pain) response in patients receiving supportive therapy for proximal plantar fasciitis. This study was a secondary analysis of data obtained from a randomized controlled trial of ambulatory adults, which examined the efficacy of 3 different foot supports for plantar fasciitis. METHODS Participants underwent diagnostic sonographic examinations of their heel at baseline and again at 3 months by a single experienced foot and ankle surgeon. Quantitative (eg, thickness) and qualitative (eg, biconvexity) characteristics of the fascia were recorded according to a standard protocol. Logistic regression models were used to identify predictors of the pain response. RESULTS Seventy patients completed a baseline evaluation, and 63 patients completed a 3-month follow-up assessment. The pain response was not associated with the type of foot support (P> .05). The only significant indicator of an unfavorable response in the univariate and multivariate analyses was biconvexity of the plantar fascia on sonography at presentation (multivariate odds ratio, 4.76 [95% confidence interval, 1.16-19.5; P= .030). Furthermore, changes in self-reported pain over the 3-month study period were not accompanied by alterations in plantar fascia thickness over this time (r = .056; P = .671). CONCLUSIONS We conclude that patients who present with biconvexity of the plantar fascia may be less responsive to tier 1 treatment regimens that center around mechanical support of the plantar fascia. Furthermore, follow-up measurements of the fascia in this population should not weigh heavily in decisions such as return to play.

Abstract
OBJECTIVES The primary purpose of this investigation was to determine the prevalence and spectrum of asymptomatic sonographically determined structural changes in the plantar fascia and plantar heel pad among experienced runners without a history of heel pain. METHODS Thirty-nine asymptomatic runners without a history of plantar heel pain were recruited. The following sonographic measures were recorded: power Doppler sonography in the plantar heel pad and plantar fascia, echo texture of the plantar heel pad, uncompressed heel pad thickness, compressed heel pad thickness, heel pad compressibility index, plantar fascia thickness, and plantar fascia echo texture. RESULTS Doppler flow was shown in the plantar heel pads of 88% (68 of 77) of heels and 92% (36 of 39) of runners. Heel pad echo texture abnormalities were found in 86% (66 of 77) of heels and 97% (38 of 39) of runners. Mean values for right and left uncompressed heel pad thickness were 13.8 and 13.7 mm, respectively. The mean heel pad compressibility indices were 0.51 for the right heel and 0.53 for the left heel. Eight percent (6 of 77) of fat pads in 10% (4 of 39) of runners had abnormal compressibility indices. Doppler flow was present in the plantar fascia in 31% (24 of 77) of heels and 44% (17 of 39) of runners. The mean plantar fascia thicknesses were 3.78 mm for the right and 3.87 mm for the left. Forty-eight percent (37 of 77) of heels had an abnormal plantar fascia echo texture. CONCLUSIONS At least 1 potentially abnormal sonographic finding was present in each heel of all asymptomatic runners in this study. Consequently, sonographic abnormalities in the plantar heel should be interpreted within the clinical context when evaluating runners.

Abstract
BACKGROUND One of the most common causes of heel pain is plantar fasciitis; however, there are other pathologic disorders that can mimic the symptoms and clinical presentation of this disorder. The purpose of this study was to retrospectively review the prevalence of various pathologic disorders on ultrasound in patients with proximal plantar heel pain. METHODS The medical records and diagnostic ultrasound reports of patients presenting with plantar heel pain between March 1, 2006, and March 31, 2007, were reviewed retrospectively, and the prevalence of various etiologies was collected. The inclusion criteria were based on their clinical presentation of plantar fasciitis or previous diagnosis of plantar fasciitis from an unknown source. Ultrasound evaluation was then performed to confirm the clinical diagnosis. RESULTS We examined 175 feet of 143 patients (62 males and 81 females; age range, 16-79 years). Plantar fibromas were present in 90 feet (51%). Plantar fasciitis was diagnosed in 128 feet (73%). Coexistent plantar fibroma and plantar fascial thickening was found in 63 feet (36%). Of the 47 feet that were negative for plantar fasciitis on ultrasound, 27 (57%) revealed the presence of plantar fibroma. CONCLUSIONS Diagnostic ultrasound can effectively and safely identify the prevalence of various etiologies of heel pain. The high prevalence of plantar fibromas and plantar fascial tears cannot be determined by clinical examination alone, and, therefore, ultrasound evaluation should be performed for confirmation of diagnosis.

Abstract
[Purpose] The purpose of this research was to analyze the efficacy of extracorporeal shock wave therapy for the treatment of stroke patients with plantar fasciitis. [Subjects and Methods] This study included 10 stroke patients diagnosed with plantar fasciitis who were administered 3 sessions of extracorporeal shock wave therapy per week. After the last session, they performed stretching exercises for their Achilles tendon and plantar fascia for 30 min/day, 5 times a week for 6 months. The following parameters were measured and compared prior to therapy, 6 weeks after therapy, and 6 months after therapy: thickness of the plantar fascia, using an ultrasonic imaging system; degree of spasticity, using a muscle tension measuring instrument; degree of pain, using the visual analogue scale; and gait ability, using the Functional Gait Assessment. [Results] Decreased plantar fascia thickness, spasticity, and pain and increased gait ability were noted after therapy. These changes were significantly greater at 6 months after therapy than at 6 weeks after therapy. [Conclusion] These results indicated that extracorporeal shock wave therapy reduced tension in the plantar fascia, relieving pain and improving gait ability in stroke patients.

Abstract
Objective To investigate the long-term effect of low-energy extracorporeal shock wave therapy (ESWT) for plantar fasciitis (PF) according to ultrasonography (US) findings. Methods Thirty feet of 25 patients with clinical diagnosis of PF were enrolled and divided into two groups (Apparent-US and Uncertain-US) according to US findings, such as plantar fascia thickening or hypoechogenicity. Inclusion criteria were symptom duration >6 months and a fair or poor grade in Roles-Maudsley score (RMS). ESWT (0.10 mJ/mm2, 600 shocks) was given once a week for 6 weeks. Numeric rating scale (NRS) and RMS were evaluated prior to each ESWT session, at short-term follow-up (one week after all ESWT sessions) and long-term follow-up telephone interview (mean 24 months after ESWT). Good and excellent grade in RMS were considered as treatment success. Results Repeated measure ANOVA demonstrated that NRS significantly decreased with time after ESWT up to the long-term follow-up (time effect, p<0.001) without group-time interaction (p=0.641), indicating that ESWT equally decreased pain in both groups. Overall success rate was 63.3% (short-term follow-up) and 80.0% (long-term follow-up). In comparative analysis between groups, success rate of Apparent-US and Uncertain-US at short-term follow-up was 61.9% and 66.7%, respectively, and 85.7% and 66.7%, respectively, at long-term follow-up. Conclusion If other causes of heel pain are ruled out through meticulous physical examination and ultrasonography, low-energy ESWT in PF seems to be beneficial regardless of US findings. In terms of success rate, however, long-term outcome of Apparent-US appears to be superior to Uncertain-US.

Abstract
Plantar fasciitis (PFS) is one of the most common causes of heel pain, estimated to affect 10% of the general population during their lifetime. Ultrasound (US) imaging technique is increasingly being used to assess plantar fascia (PF) thickness, monitor the effect of different interventions and guide therapeutic interventions in patients with PFS. The purpose of the present study was to systematically review previously published studies concerning the application of US in the assessment of PF in patients with PFS. A literature search was performed for the period 2000-2012 using the Science Direct, Scopus, PubMed, CINAHL, Medline, Embase and Springer databases. The key words used were: ultrasound, sonography, imaging techniques, ultrasonography, interventional ultrasonography, plantar fascia and plantar fasciitis. The literature search yielded 34 relevant studies. Sixteen studies evaluated the effect of different interventions on PF thickness in patients with PFS using US; 12 studies compared PF thickness between patients with and without PFS using US; 6 studies investigated the application of US as a guide for therapeutic intervention in patients with PFS. There were variations among studies in terms of methodology used. The results indicated that US can be considered a reliable imaging technique for assessing PF thickness, monitoring the effect of different interventions and guiding therapeutic interventions in patients with PFS.

Abstract
BACKGROUND Plantar fasciitis is a common cause of foot pain, and although many episodes are self-limiting with short duration, 10% leave chronic symptoms. Recalcitrant cases can be managed surgically, with studies demonstrating good results in the short term but uncertainties over longer term outcomes. PURPOSE To assess the outcome following surgical intervention for patients with plantar fasciitis. STUDY DESIGN Case series; Level of evidence, 4. METHODS Seventy-nine patients were identified from operative diaries undergoing plantar fasciotomy surgery between 1993 and 2009. They were contacted to investigate long-term results using self-reported outcome measures. RESULTS Sixty-eight responses were received (86% response rate), with an average of 7 years (range, 1-15 years) of follow-up. Patients reported an average reduction in pain by visual analog scale of 79%, and 84% of patients were happy with the surgical results. Greater success was achieved in patients with shorter duration of symptoms preoperatively. No deterioration in success was seen over time. CONCLUSION Plantar fasciotomy surgery for plantar fasciitis remains controversial, with biomechanical arguments against surgery; however, this article reports good success following surgery over a long follow-up period. The results of current operative techniques need to be fully investigated for longer term success, as do the outcomes of newer nonoperative management strategies.

Abstract
Objectives To explore the anatomy of the plantar aponeurosis (PA) and its biomechanical effects on the first metatarsophalangeal (MTP) joint and foot arch. Methods Anatomic parameters (length, width and thickness of each central PA bundle and the main body of the central part) were measured in 8 cadaveric specimens. The ratios of the length and width of each bundle to the length and width of the central part were used to describe these bundles. Six cadaveric specimens were used to measure the range of motion of the first MTP joint before and after releasing the first bundle of the PA. Another 6 specimens were used to evaluate simulated static weight-bearing. Changes in foot arch height and plantar pressure were measured before and after dividing the first bundle. Results The average width and thickness of the origin of the central part at the calcaneal tubercle were 15.45 mm and 2.79 mm respectively. The ratio of the length of each bundle to the length of the central part was (from medial to lateral) 0.29, 0.30, 0.28, 0.25, and 0.27, respectively. Similarly, the ratio of the widths was 0.26, 0.25, 0.23, 0.19 and 0.17. The thickness of each bundle at the bifurcation of the PA into bundles was (from medial to lateral) 1.26 mm, 1.04 mm, 0.91 mm, 0.84 mm and 0.72 mm. The average dorsiflexion of the first MTP joint increased 10.16° after the first bundle was divided. Marked acute changes in the foot arch height and the plantar pressure were not observed after division. Conclusions The first PA bundle was not the longest, widest, or the thickest bundle. Releasing the first bundle increased the range of motion of the first MTP joint, but did not acutely change foot arch height or plantar pressure during static load testing.

Abstract
PURPOSE Eccentric exercise has become the treatment of choice for Achilles tendinopathy. However, little is known about the acute response of tendons to eccentric exercise or the mechanisms underlying its clinical benefit. This research evaluated the sonographic characteristics and acute anteroposterior (AP) strain response of control (healthy), asymptomatic, and symptomatic Achilles tendons to eccentric exercise. METHODS Eleven male adults with unilateral midportion Achilles tendinopathy and nine control male adults without tendinopathy participated in the research. Sagittal sonograms of the Achilles tendon were acquired immediately before and after completion of a common eccentric rehabilitation exercise protocol and again 24 h later. Tendon thickness, echogenicity, and AP strain were determined 40 mm proximal to the calcaneal insertion. RESULTS Compared with the control tendon, both the asymptomatic and symptomatic tendons were thicker (P < 0.05) and hypoechoic (P < 0.05) at baseline. All tendons decreased in thickness immediately after eccentric exercise (P < 0.05). The symptomatic tendon was characterized by a significantly lower AP strain response to eccentric exercise compared with both the asymptomatic and control tendons (P < 0.05). AP strains did not differ in the control and asymptomatic tendons. For all tendons, preexercise thickness was restored 24 h after exercise completion. CONCLUSIONS These observations support the concept that Achilles tendinopathy is a bilateral or systemic process and structural changes associated with symptomatic tendinopathy alter fluid movement within the tendon matrix. Altered fluid movement may disrupt remodeling and homeostatic processes and represents a plausible mechanism underlying the progression of tendinopathy.

Abstract
BACKGROUND The purpose of this study was to determine whether changes in plantar fascia thickness are a reliable gauge of efficacy of treatment protocols for plantar fasciitis. METHODS Thirty-nine feet (30 patients) with plantar fasciitis received an ultrasound examination to measure the thickness of the medial band of the plantar fascia. Each patient assessed his or her pain using the visual analogue scale. Following various treatments, a second ultrasound examination was performed and the thickness of the plantar fascia was again measured and subjective pain level assessed. RESULTS Twenty-nine feet (74.4%) showed a decrease in plantar fascia thickness and a decrease in pain. One foot (2.6%) experienced an increase in fascia thickness and reported an increase in pain. Four feet (10.3%) had an increase in thickness of the plantar fascia and reported no change in pain level. Three feet had minor increases in fascia thickness but reported a decrease in pain (7.7%). One foot (2.6%) had no change in fascia thickness but a decrease in pain and one foot (2.6%) had a decrease in the plantar fascia but no change in pain level. The average reduction in fascia thickness was 0.82 mm ± 1.04 mm, correlating with an average improvement in pain of 3.64 ± 2.7 (P < 0.005). CONCLUSIONS This study provides evidence that changing thickness of the plantar fascia is a valid objective measurement to assess effectiveness of new or existing treatment protocols.

Two sonographers independently imaged the plantar fascia in both longitudinal and transverse planes. Volunteers were assessed twice to evaluate intrarater reliability. Quantitative evaluation of the echogenicity of the plantar fascia was performed by measuring the mean gray level of the region of interest using Digital Imaging and Communications in Medicine viewer software. RESULTS Sonographic evaluation of the thickness of the plantar fascia showed high reliability. Sonographic evaluations of the presence or absence of hypoechoic change in the plantar fascia showed surprisingly low agreement. The reliability of gray-scale evaluations appears to be much better than subjective judgments in the evaluation of echogenicity. Transverse scanning did not show any advantage in sonographic evaluation of the plantar fascia. CONCLUSIONS The reliability of sonographic examination of the thickness of the plantar fascia is high. Mean gray-level analysis of quantitative sonography can be used for the evaluation of echogenicity, which could reduce discrepancies in the interpretation of echogenicity by different sonographers. Longitudinal instead of transverse scanning is recommended for imaging the plantar fascia.

Fabrikant JM, Park TS. Plantar fasciitis (fasciosis) treatment outcome study: plantar fascia thickness measured by ultrasound and correlated with patient self-reported improvement. Foot (Edinb) 2011; 21:79-83. [PMID: 21398108 DOI: 10.1016/j.foot.2011.01.015] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2010] [Revised: 01/27/2011] [Accepted: 01/31/2011] [Indexed: 02/04/2023]
Abstract
Ultrasound, well recognized as an effective diagnostic tool, reveals a thickening of the plantar fascia in patients with plantar fasciitis/fasciosis disease. The authors hypothesized that ultrasound would also reveal a decrease in the plantar fascia thickness for patients undergoing treatment for the disease, a hypothesis that, heretofore, had been only tested on a limited number of subjects. They conducted a more statistically significant study that found that clinical treatment with injection and biomechanical correction does indeed diminish plantar fascia thickness as shown on ultrasound. The study also revealed that patients experience the most heightened plantar fascia tenderness toward the end of the day, and improvement in their symptomatic complaints were associated with a reduction in plantar fascia thickness. As a result, the authors conclude that office-based ultrasound can help diagnose and confirm plantar fasciitis/fasciosis through the measurement of the plantar fascia thickness. Because of the advantages of ultrasound--that it is non-invasive with greater patient acceptance, cost effective and radiation-free--the imaging tool should be considered and implemented early in the diagnosis and treatment of plantar fasciitis/fasciosis.

Abstract
BACKGROUND The enthesis of the plantar fascia is thought to play an important role in stress dissipation. However, the potential link between entheseal thickening characteristic of enthesopathy and the stress-dissipating properties of the intervening plantar fat pad have not been investigated. PURPOSE This study was conducted to identify whether plantar fat pad mechanics explain variance in the thickness of the fascial enthesis in individuals with and without plantar enthesopathy. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS The study population consisted of 9 patients with unilateral plantar enthesopathy and 9 asymptomatic, individually matched controls. The thickness of the enthesis of the symptomatic, asymptomatic, and a matched control limb was acquired using high-resolution ultrasound. The compressive strain of the plantar fat pad during walking was estimated from dynamic lateral radiographs acquired with a multifunction fluoroscopy unit. Peak compressive stress was simultaneously acquired via a pressure platform. Principal viscoelastic parameters were estimated from subsequent stress-strain curves. RESULTS The symptomatic fascial enthesis (6.7 ± 2.0 mm) was significantly thicker than the asymptomatic enthesis (4.2 ± 0.4 mm), which in turn was thicker than the enthesis (3.3 ± 0.4 mm) of control limbs (P < .05). There was no significant difference in the mean thickness, peak stress, peak strain, or secant modulus of the plantar fat pad between limbs. However, the energy dissipated by the fat pad during loading and unloading was significantly lower in the symptomatic limb (0.55 ± 0.17) when compared with asymptomatic (0.69 ± 0.13) and control (0.70 ± 0.09) limbs (P < .05). The sonographic thickness of the enthesis was correlated with the energy dissipation ratio of the plantar fat pad (r = .72, P < .05), but only in the symptomatic limb. CONCLUSION The energy-dissipating properties of the plantar fat pad are associated with the sonograpic appearance of the enthesis in symptomatic limbs, providing a previously unidentified link between the mechanical behavior of the plantar fat pad and enthesopathy.

Abstract
BACKGROUND Magnetic Resonance Imaging (MRI) is generally only indicated in patients with plantar heel pain who have atypical symptoms or who do not improve with appropriate management. MATERIALS AND METHODS This study retrospectively reviewed the MRI findings of 112 patients with heel pain divided into two groups consisting of 50 patients with persistent pain despite appropriate treatment and 62 patients with atypical heel pain. RESULTS Of the 50 patients with persistent heel pain, 38 (76%) of MRIs confirmed the diagnosis of plantar fasciitis. Of the 62 patients who had presented with atypical symptoms or signs, 21 patients had presented with night pain and the remaining 41 had presented with acute pain, tenderness of the lateral or medial aspect of the heel, significant swelling, neurological features or pain posterior to the insertion of the plantar fascia. Patients with night pain were shown to have plantar fasciitis associated with calcaneal marrow edema in 15 (71.4%) cases (p < 0.05). One patient presenting with night pain was found to have a plantar arterio-venous malformation. Acute pain was associated with plantar fascia tears in 4 out of 9 (p < 0.05). CONCLUSION MRI may provide reassurance in cases of persistent heel pain but rarely changes the management. In cases of atypical heel pain, MRI may demonstrate other pathology such as plantar fascia tearing, calcaneal edema or arteriovenous malformation.
