Prevalencia y biometría del espolón calcáneo en la población chilena: estudio radiológico / Prevalence and biometry of the calcaneal spur in the Chilean population: radiological study

RESUMEN: El dolor en la región calcánea del pie afecta aproximadamente a un tercio de los adultos mayores de 65 años. Asimismo, una gran cantidad de sujetos que consultan por esta condición, revelan hallazgos radiológicos de un crecimiento anormal en el hueso calcáneo, en su cara plantar, en forma de gancho denominado espolón calcáneo (EC). El objetivo del presente estudio fue relacionar la prevalencia y biometría de los EC en individuos chilenos según sexo y edad. Se realizó un estudio radiológico de tipo descriptivo-correlacional donde se revisaron al azar 400 radiografías de pies en proyección lateral de 200 sujetos chilenos entre 15 y 90 años. El análisis de los 200 exámenes radiográficos mostró que en 135 (67,5 %) de ellos presentaban EC de manera unilateral o bilateral. La presencia de al menos un EC era mayor en las mujeres 104 (52 %) que en los hombres 31 (15,5 %). Sin embargo, esta diferencia no es estadísticamente significativa p= 0,621. La edad promedio de los sujetos que presentaron EC era de 60,4 años, ampliamente superior a quien no lo presentaba (43,5 años), siendo esta diferencia estadísticamente significativa P<0,05. Se puede concluir una prevalencia del 67,5 % de EC en la población de estudio, mayor en las mujeres y directamente relacionada con la edad. Esta información podría ser de gran valor morfológico y médico debido a la escasa literatura existente sobre esta materia en individuos chilenos.

SUMMARY: Pain in the talar region of the foot affects approximately one third of people over 65 years of age. Likewise, a large number of patients who consult for this condition reveal radiological findings of an abnormal growth of the hook-shaped calcaneus called a calcaneal spur (CS). The objective of the present study was to relate the prevalence and biometrics of CS in Chilean individuals according to sex and age. A descriptive-correlational radiological study was carried out where 400 lateral projection radiographs of the feet of 200 Chilean patients between 15 and 90 years of age were randomly reviewed. The analysis of the 200 people examined showed that 135 (67.5%) presented CS unilaterally or bilaterally. The presence of at least one CS is greater in the female sex 104 (52%) than in the male sex 31 (15.5%), however, this difference is not statistically significant p = 0.621. The average age of the people who presented CS is 60.43 years, much higher than those who do not present (43.51 years), this difference being statistically significant P = Sig. It can be concluded a prevalence of 67.5% of CS in the study population, higher in the female sex and directly related to age. This information will be of great morphological and medical value due to the little existing literature on this matter in Chilean individuals.

The relationship between age-related incidences of heel spur with sex and side / Relación entre la incidencia del espolón calcáneo con la edad, sexo y lado

SUMMARY: Heel spur is an osteophytic protrusion larger than 2 mm that lies just anterior to the tuberosity of the calcaneus. Heel spur can be of two types: plantar heel spur and dorsal heel spur. The aim of this study was to evaluate the relationship between the heel spurs incidence with age, sex and side. A total of 2000 bilateral radiographs of 1000 patients (518 men and 482 women) aged 20-93 years who applied to Terme state hospital, Samsun, Turkey due to trauma were examined. Patients were grouped into 10 year age ranges (20-29 years; 30-39 years; 40-49 years; 50-59 years; 60-69 years and over 70 years). The incidences of plantar heel spur, dorsal heel spur, and both were evaluated according to age, sex and side relations. Plantar or dorsal heel spurs were detected in 32.6 % (326 patients) of the patients. The incidences of plantar heel spur, dorsal heel spur, plantar and dorsal heel spur were 26.0 %, 16.9 %, and 10.3 % respectively. According to sex, the incidence of plantar heel spur was higher in women in all age groups. Although the incidence of dorsal heel spur was higher in men in the 6th decade, it was more common in women in other age groups. The incidence of plantar heel spur was 2.615 times higher in the right foot and 2.810 times higher in the left foot in women. As the age increased, the risk of plantar heel spur increased 1.060 times in the right foot and 1.061 times in the left foot. The incidence of dorsal heel spur was 1.510 times higher in the right foot and 1.715 times higher in the left foot in women. As the age increased, the incidence of dorsal heel spur increased in both feet and this increase was 1.055 times in both feet.

RESUMEN: El espolón calcáneo es una protuberancia osteofítica de más de 2 mm que se encuentra por delante de la tuberosidad del calcáneo. El espolón calcáneo puede ser de dos tipos: espolón calcáneo plantar y espolón calcáneo dorsal. El objetivo de este estudio fue evaluar la relación entre la incidencia de espolón calcáneo con la edad, el sexo y el lado. Se examinaron un total de 2000 radiografías bilaterales de 1000 pacientes (518 hombres y 482 mujeres) de 20 a 93 años de edad que fueron solicitadas en el hospital estatal de Terme, Samsun, Turquía debido a un traumatismo. Los pacientes se agruparon en rangos de edad de 10 años (20-29 años; 30-39 años; 40-49 años; 50-59 años; 60-69 años y mayores de 70 años). Las incidencias de espolón calcáneo plantar, espolón calcáneo dorsal y ambos se evaluaron de acuerdo con la edad, el sexo y lados. Se detectaron espolones calcáneos plantares o dorsales en el 32,6 % (326 pacientes) de los pacientes. Las incidencias de espolón calcáneo plantar, espolón calcáneo dorsal, espolón calcáneo plantar y dorsal fueron del 26 %, 16,9 % y 10,3 %, respectivamente. Según el sexo, la incidencia de espolón calcáneo plantar fue mayor en mujeres en todos los grupos de edad. Aunque la incidencia del espolón calcáneo dorsal fue mayor en hombres en la sexta década, era más común en mujeres en otros grupos de edad. La incidencia de espolón calcáneo plantar fue 2,6 veces mayor en el pie derecho y 2,8 veces mayor en el pie izquierdo en mujeres. A medida que aumentaba la edad, el riesgo de espolón calcáneo plantar aumentaba 1,06 veces en el pie derecho y 1,061 veces en el pie izquierdo. La incidencia de espolón calcáneo dorsal fue 1,510 veces mayor en el pie derecho y 1,715 veces mayor en el pie izquierdo en mujeres. A medida que aumentaba la edad, la incidencia de espolón calcáneo dorsal aumentaba en ambos pies y este aumento era de 1,055 veces en ambos pies.

The frequency of Achilles and plantar calcaneal spurs in gout patients

Background/aim: Gout may cause various radiographic abnormalities such as cartilage loss, spurs, sclerosis, and periostal new bone formation. The purpose of this study was to investigate the frequency of Achilles and plantar spurs and related factors in gout patients. Matherial and methods: We performed a retrospective review of gout patients, treated at Hacettepe University hospitals between 2014 and 2019. We identified patients from the hospital records using the ICD-10 code (M10). Demographic and clinical features, comorbidities, and foot radiographies were collected. The radiographies were evaluated by a rheumatologist (U.K.) who was experienced in musculoskeletal radiography. Factors predicting the spurs were analyzed by logistic regression analysis. Results: 181 patients who had lateral foot radiograph were included in this study. Eighty-one (44.7%) patients had score ≥ 2 Achilles spur, 81 (44.7%) patients had score ≥ 2 plantar spur, and 22 (12.1%) patients had no spur. Age, disease duration, duration between the gout diagnosis and appearing spur, the presence of metabolic comorbidities and hypertension were higher in both Achilles and plantar spurs than no spur group. Forty (22.1%) patients had score ≥ 2 both Achilles and plantar spur. In this group, the mean age was older and the proportion of metabolic comorbidities was higher than the groups of Achilles and plantar spur with a score 0 or 1. Predictor of the development of large or moderate-severe calcaneal spur was the existence of metabolic comorbidity [OR (95% CI): 3.49 (1.11­11.0) and p = 0.033]. Conclusion: The presence of metabolic comorbidities increases the frequency of calcaneal spurs in gout patients. This condition can be explained by the impaired microvascular structure and increased hypoxia resulting in calcification on the tendon and ligament insertion sites.

Radiologic and Demographic Characteristics of Patients With Plantar Calcaneal Spur.

Many people with heel pain in the general population are often diagnosed with plantar calcaneal spurs (PCS). The aim of this study was to evaluate the radiological and demographic characteristics of PCS patients and to compare the differences with the control group. In 2018, 420 patients with weightbearing lateral ankle X-ray images were included in the study. The patients were divided into 2 groups as PCS group and control group. Groups were compared age and age group (20-29, 30-39, 40-49, 50-59, 60-69, 70 and over) weight, height, body mass index (<25, 25-30, >30), chronic diseases as demographically and were also compared radiologically as calcaneal inclination angle (CIA), lateral talocalcaneal angle (LTCA), Bohler angle and Gissane angle. A statistically significant relationship was found between gender and PCS. Plantar calcaneal spur is more common in females than in males (X2:8.101, p < .03). PCS was less common in patients with BMI <25 and 25-29.9, whereas PCS is more common in patients with BMI >30 (X2:7.698, p < .021). Although the CIA angle was within normal limits in both groups, it was significantly lower in patients with PCS than in the control group(p < .05). There was no statistically significant difference between the 2 groups in terms of age, chronic disease, LTCA, Bohler angle, Gissane angle. Female gender and obesity are among the risk factors for PCS formation. CIA may have an important role in PCS formation. In order to clarify the etiology and pathophysiology of PCS, further studies with radiological features are needed.

Morphometric analysis of calcaneal (heel) spurs in ancient and modern Anatolian populations / Análisis morfométrico de los espolones calcáneos en poblaciones de Anatolia antiguas y modernas

SUMMARY: Heel spurs are the bony protrusion seen especially on the dorsal and plantar face of the calcaneus bone at the attachment site of the muscles. It was aimed herein to obtain data about the life styles, daily lives, and especially the socioeconomic structures of modern and ancient Anatolian populations by evaluating the prevalence, location, age, and gender differences of heel spurs on the calcaneus and comparing these findings between the populations. Herein, the 251 calcaneus bones of 137 skeletons, which had been previously analyzed paleodemographically and dated to the Middle Ages, and 68 calcaneus bones belonging to a modern population, whose gender was unknown but lived in Anatolia, were examined in terms of heel spurs. In the current study, the presence of dorsal, plantar, or both dorsal/plantar heel spurs on these in 251 calcaneus bones was 43.9 %, 11.1 %, and 10.3 %, respectively. The presence of dorsal, plantar, or both dorsal/plantar heel spurs was determined as 22 %, 3 %, and 1.5 %, respectively, among the 68 calcaneus bones belonging to the modern population. When a comparison was made of the current study with studies in the literature on modern and prehistoric populations, a higher prevalence of heel spurs was found in prehistoric samples than in modern populations. It is our belief that this situation may have derived from the heavy labor force, environmental, or sociocultural differences in ancient Anatolian populations, insufficiency of vital materials due to inadequate industrial conditions, and the solution of anatomical disruption. In addition, the findings determined herein will guide the development of future and industrial studies on the foot and foot structure.

RESUMEN: Los espolones del talón son la protuberancia ósea que se ve especialmente en la cara dorsal y plantar del hueso calcáneo en el sitio de inserción de los músculos. El objetivo de este trabajo consistió en obtener datos sobre los estilos de vida, la vida cotidiana y, especialmente, las características socioeconómicas de las poblaciones anatolias modernas y antiguas mediante la evaluación de la prevalencia, la ubicación, la edad y las diferencias de sexo de los espolones calcáneos y comparar estos hallazgos entre los poblaciones. La muestra consistió en 251 calcáneos correspondientes a 137 esqueletos, que habían sido previamente analizados paleodemográficamente y fechados en la Edad Media; también se incluyeron 68 calcáneos pertenecientes a una población moderna de Anatolia, sin distinción de sexo. De la muestra de 251 calcáneos, se encontraron espolones calcáneos dorsales, plantares y dorsales/plantares, en el 43,9%, 11,1 % y 10,3 %, respectivamente. La presencia de espolones calcáneos dorsales, plantares y dorsales/plantares se determinó en el 22%, 3% y 1,5%, respectivamente, entre los 68 calcáneos pertenecientes a la población moderna. Cuando se realizó una comparación del estudio actual con la literatu- ra sobre poblaciones modernas y prehistóricas, se encontró una mayor prevalencia de espolones calcáneos en muestras prehistóricas que en poblaciones modernas. Creemos que esta situación puede haberse derivado a la gran fuerza de trabajo, y las diferencias ambientales o socioculturales en las antiguas poblaciones de Anatolia, la insuficiencia de materiales vitales debido a las condiciones industriales inadecuadas produjo la alteración anatómica. Además, los hallazgos aquí determinados guiarán el desarrollo de estudios futuros e industriales sobre la estructura del pie.

The age dependent change in the incidence of calcaneal spur.

OBJECTIVE: The aim of the present study was to evaluate the association between the calcaneal spur incidence and age, gender and side. METHODS: Lateral ankle X-rays of 1335 patients (550 (41.2%) females and 758 (58.8) males; mean age: 46.5 ± 13.5 years) who referred to our hospital because of trauma were reviewed. Incidence of plantar calcaneal spur, posterior calcaneal spur and association of such incidences with age, gender and side were all evaluated. RESULTS: Incidences of plantar calcaneal spur and posterior calcaneal spur were detected as 32.2% (male: 31%, female: 34%) and 13.1% (male: 11%, female: 16%), respectively. Incidence of plantar calcaneal spur increased by age whereas there was not any association with gender and location. The highest incidence was detected as 41.8% over 70 years of age. Incidence of posterior calcaneal spur increased by age and female gender whereas no significant association was observed with location. The highest incidence was detected as 22.3% between 61 and 70 years of age. CONCLUSION: Incidences of plantar and posterior calcaneal spur were detected as 32.2% and 13.1%, respectively. Both plantar and posterior calcaneal spur incidence increases by age. Posterior calcaneal spur occurs significantly more frequently in females while, no difference is found between the males and females in incidence of the plantar calcaneal spur. LEVEL OF EVIDENCE: Level IV, diagnostic study.

Calcaneal spurs among San and Khoi skeletons.

Only few studies considered the prevalence of calcaneal enthesophytes commonly called heel spurs among historic skeleton samples. In the present study the frequency of plantar calcaneal spurs among 54 19(th) century Khoisan skeletons was analyzed. Five individuals (9.6 %) had a plantar calcaneal spur at the right side or left side. Calcaneal spurs were more likely to occur in older individuals. More than 20 % of the individuals aged between 40 and 60 years (mature) showed plantar spurs, while 6.2 % of the individuals aged between 20 and 40 years had plantar spurs; however this difference was not significant. No sex differences were present in the prevalence of calcaneal spurs. Male and female individuals did not differ in the metric dimensions of the calcanceal spurs significantly.

Association of Achilles tendinopathy and plantar spurs.

Plantar spurs and Achilles tendinopathy are common causes of heel pain. In the authors' practice, it was anecdotally noted that patients with Achilles tendinopathy often presented with plantar spurs. Nonetheless, there is a shortage of studies investigating whether Achilles tendinopathy and plantar spurs exist concomitantly. A better understanding of the association between the 2 pathologies might help physicians recognize and treat both conditions, educate patients about Achilles tendinopathy and plantar spurs, and ultimately investigate possible underlying causes of both pathologies that could be addressed together. The authors examined the prevalence of plantar spurs in patients diagnosed with Achilles tendinopathy as well as demographic differences within the unilateral and bilateral Achilles tendinopathy populations. A total of 785 patient records were retrospectively reviewed. Mean patient age was 56.2±15.5 years (46.9% men and 53.1% women). Seventy-two (9.2%) patients were affected bilaterally by Achilles tendinopathy. Lateral radiographs were reviewed by an orthopedic surgeon to identify the presence of plantar spurs. A total of 329 (41.9%) patients with Achilles tendinopathy were found to have a concomitant plantar spur. Patients with unilateral Achilles tendinopathy and a plantar spur were more likely to be women (58.7% vs 49.8%, P=.020) and older (62.7 vs 51.7 years, P<.001). In the bilateral Achilles tendinopathy group, there were 46 (63.9%) patients with at least one foot presenting with a plantar spur. The study's findings suggest a significant association between Achilles tendinopathy and plantar spurs. Older women with Achilles tendinopathy are at greater risk of being affected by plantar spurs.

Changes in prevalence of calcaneal spurs in men & women: a random population from a trauma clinic.

BACKGROUND: This study reports the changing prevalence of ankle (Achilles and plantar) spurs with age, in order to comment on their significance to rheumatologists. METHODS: 1080 lateral ankle radiographs from each of 9 (50 men and 50 women) age cohorts from 2 to 96 years old of patients attending a trauma clinic were examined and spurs classified as small or large. RESULTS: The prevalence of both Achilles and plantar spurs in relation to the age categories and sex was variable. Overall, there was 38% of the population who had a spur (Achilles or plantar) and only third (11%) with spurs at both sites (Achilles and plantar). Large spurs were more prevalent in older individuals (40 to 79 years). There were no large plantar spurs in individuals <40 years of age and only 2% for the Achilles. The prevalence of spurs (Achilles and plantar) was significantly higher for woman than men in individuals <50 years of age. There was a notable moderate positive correlation (r = 0.71) between both plantar and Achilles spurs for women <30 years of age but no correlation for men (r = -0.03). CONCLUSION: Plantar and Achilles spurs are highly prevalent in older people and the radiographic appearance of spurs differs between men and women. In individuals < 50 years of age, spur (Achilles and plantar) formation is more common in women than in men. Additionally, there was a notable moderate positive correlation between Achilles and plantar spurs for women <30 years of age.

The conundrum of calcaneal spurs: do they matter?

BACKGROUND: Chronic plantar heel pain is a common and potentially debilitating condition, often caused by plantar fasciitis. Plantar calcaneal spurs were originally considered the cause of plantar fasciitis but are now regarded as an incidental finding by most authors. We aimed to test this hypothesis and to investigate predisposing factors for the development of spurs. METHODS: We reviewed all lateral ankle X rays taken in our institution over a 6-month period and identified all X rays demonstrating calcaneal spurs. Then, we identified a similar number of age- and sex-matched controls without spurs. We contacted both groups by telephone and compared symptoms of heel pain, plantar fasciitis, associated comorbidities, and foot and ankle outcome scores (FAOSs). RESULTS: We reviewed the X rays of 1103 consecutive patients and found a spur prevalence of 12.4%, more common in women and older patients. Questioning of the spur group and control group found a higher body mass index in the spur group. Patients with spurs were 4 times more likely to have diabetes mellitus and 10 times more likely to have lower-limb osteoarthritis. Patients with spurs had more foot pain and poorer FAOS than the control group, even when patients with plantar fasciitis were excluded. CONCLUSION: Our results demonstrate that the presence of a plantar calcaneal spur may be an indicator of foot pain independent of plantar fasciitis. Although spurs may not cause foot pain themselves, they may be an indication of other associated conditions. CLINICAL RELEVANCE: We have demonstrated the relevance of a radiographic finding once considered irrelevant.

Plantar fasciitis and the calcaneal spur: Fact or fiction?

BACKGROUND: Plantar fasciitis is a common diagnosis in patients presenting with heel pain. The presence of co-existing calcaneal spurs has often been reported but confusion exists as to whether it is a casual or significant association. METHODS: The lateral heel radiographs of nineteen patients with a diagnosis of plantar fasciitis and nineteen comparison subjects with a lateral ankle ligament sprain matched for age and sex, were reviewed independently by two observers. Objective measurements of calcaneal spur length and a subjective grading of spur size were recorded. RESULTS: There was a significantly higher prevalence of calcaneal spurs in the cases than the comparison group (89% versus 32%; McNemar chi-square=9.09, df=2, p=0.00257). There was good inter- and intra-observer agreement. CONCLUSION: The current study has demonstrated a significant association between plantar fasciitis and calcaneal spur formation. Further research is warranted to assess whether the association is causal.

Anatomic relationship of heel spur to surrounding soft tissues: greater variability than previously reported.

The stimulating factor for the development of heel spur (calcaneal exostosis) is controversial. In a sample of elderly cadaveric specimens, using radiographic, gross morphological, and histological investigation, we demonstrate that heel spurs are generally not found in the trajectory of traction from the plantar aponeurosis enthesis or plantar muscles. Rather, they are variably associated with soft tissues including loose connective tissue, fibrocartilage, muscle, and aponeurosis. Furthermore, the bony trabeculae of the spur are not aligned in the direction of soft tissue traction, but rather in the direction of stress on the calcaneus during walking and standing. These results substantiate the view that the heel spur may be a skeletal response to stress and may serve to protect the bone against the development of microfractures.
