The association of calcaneal spur length and clinical and functional parameters in plantar fasciitis

Effect of acetic acid shockwave phonophoresis on spur morphology, foot pain and function in patients with calcaneal spur: A randomised controlled trial

OBJECTIVE

To investigate the effect of acetic acid shockwave phonophoresis on spur morphology, foot pain, and function in patients with calcaneal spurs.

DESIGN

A double-blinded, randomised clinical trial.

SETTING

Outpatients physical therapy clinics.

PARTICIPANTS

One hundred forty-seven patients with calcaneal spurs, 18-65 years old, were randomly allocated to three equal groups.

INTERVENTION

The study group (A) received acetic acid shockwave phonophoresis plus conventional physical therapy. The study group (B) received shockwave therapy plus conventional physical therapy. The control group received conventional physical therapy programme only. Interventions were applied twice a week for 3 weeks.

OUTCOME MEASURES

Calcaneal spur width, calcaneal spur length, pain intensity level, pain pressure threshold and foot and ankle ability measure activities of daily living subscale were measured at baseline, after 3 weeks of interventions and after 4 weeks of follow-up with no intervention.

RESULTS

Between-group differences were observed for calcaneal spur width and length, pain intensity, pain pressure threshold and function after 3 weeks favouring Group A (p < 0.001). Mean differences (95% CI) between study groups were -1.11 mm (-1.46, -0.77) for spur width; -1.34 mm (-1.67, -1.01) for spur length; -20.71 mm (-24.66, -16.77) for pain; 1.45 kg/cm2 (1.05, 1.85) for pain pressure threshold; and 12.16 points (9.24, 15.09) for function after 3 weeks.

CONCLUSIONS

Acetic acid shockwave phonophoresis combined with exercise clinically and statistically improves calcaneal spur width, length, pain intensity, pain pressure threshold and foot function more than shockwave therapy alone or conventional physical therapy. This method might be considered an effective, feasible, safe, non-invasive and locally applicable treatment for heel spurs.

Investigation of The Effectiveness of Extracorporeal Shock Wave Therapy in Patients Diagnosed with Plantar Fasciitis: Comparison of Radial and Focus Applications

The aim of the study was to investigate the effectiveness of radial and focus (extracorporeal shock wave therapy) ESWT treatment on pain, function and size of the calcaneal spur in patients with clinical and radiological diagnosis of plantar fasciitis. A total of 112 patients aged between 18 and 95 years, were divided into 2 groups; group 1, rESWT (2.4 bar 12 hz 2000 beats), group 2 received fESWT (0.14 bar 14 hz 1000 beats) 3 times a week for 3 weeks. All patients were evaluated using the Visual Analog Scale (VAS)-pain and Foot Function Index before and after the treatment, at 4 week and 12 weeks. Calcaneal spur size was measured radiographically in the patients before and after the treatment at the 12th week follow-up. According to our records, VAS scores were found to be similar between the groups before treatment and at follow-ups (all p > .05). In both groups, a significant decrease in VAS scores was found in the follow-ups compared to before treatment (p < .001). FFI total, pain, activity and disability scores were found to be similar between the groups before treatment and at follow-up (all p > .05). In both groups, a significant decrease in Foot Function Index scores was found in the follow-ups compared to before treatment (p < .001). Both of rESWT and fESWT were effective in plantar fasciitis treatment there were no significant difference between 2 modalities in long term.

The association of demographic, psychological, social and activity factors with foot health in people with plantar heel pain

BACKGROUND

Plantar Heel Pain (PHP) can be a debilitating musculoskeletal condition from which only 50% recover within a year due to poor understanding of the mechanisms explaining severity and predicting outcomes specific to PHP.

OBJECTIVE

To explore associations between biopsychosocial variables and the severity of people with PHP. Secondly, to determine what combination of self-reported factors distinguishes people with PHP from other foot pain (OFP).

METHODS

We collected data from 235 participants, including 135 (%57) PHP (age 44 ± 12 years, 66% female) and 99 OFP (%43) (age 38 ± 11 years, 57% female) using 5 demographic, 13 biomedical, 8 psychological, 3 social and 8 activity-related factors. These were tested in linear and logistic regression models.

RESULTS

Quality of life (QoL) (β = 0.35; p < 0.001), education (β = -0.22; p = 0.003), gender (β = -0.20; p = 0.007), morning pain duration (β = -0.18; p = 0.01) and disease duration (β = -0.15; p = 0.040) were significantly associated with severity of PHP. The second model, without QoL, showed that having sensitisation (β = -0.18; p = 0.002) and a higher level of morning pain (β = -0.20; p = 0.01) are associated with severity. The logistic regression results revealed that people with PHP tend to have a systemic disease (OR = 3.34; 1.53-7.76), express more kinesiophobia (OR = 1.02; 1.01-1.14), are less likely to have previous injuries (OR = 0.40; 0.19-0.81), worse morning pain (OR = 1.02; 1.01-1.03) and standing pain (OR = 2.60; 1.39-4.87) compared to people with OFP.

CONCLUSIONS

People with PHP have higher associated levels of a range of psychological, social and activity related factors than people with OFP. The findings highlight the importance of considering psychosocial assessments alongside physical examination.

Clinical Study of a Four-Step Program for the Treatment of Plantar Fasciitis with Bone Spurs

OBJECTIVE

The most common causes of plantar and heel pain are plantar fasciitis and calcaneal spurs, and they often co-exist. Surgery is a recognized treatment for refractory plantar fasciitis. However, few studies have proposed treatment options for patients with metatarsophalangeal fasciitis with bone spurs. Accordingly, this study's purpose was to propose a four-step surgical regimen, and to improve the surgical outcome of plantar fasciitis with osteophytes and to establish a procedure for surgical treatment.

METHODS

Retrospective analysis of 45 patients suffering from plantar fasciitis with bone spurs from 2020 to 2023. All patients underwent a four-step procedure, including plantar fascia release, calcaneal spur grinding, inflammatory tissue removal, and calcaneal burr decompression. The imaging parameters and functional scores were recorded before and after the operation. The objective evaluation included the measurement of calcaneal spur length on radiographs. Clinical evaluation included the American Orthopaedic Foot and Ankle Society (AOFAS), the Visual Analog Scale (VAS), and the Foot and Ankle Outcome Scale (FAOS). Measurement data that conformed to normal distribution were expressed as (x2 ± s), and pre-and postoperative AOFAS, FAOS, and VAS scores were compared using repeated-measures ANOVA, and preoperative and postoperative spur lengths were compared using paired t-tests.

RESULTS

The 45 patients were followed up for 3 to 30 months, (17.72 ± 8.53) months, at final follow-up, the patient's AOFAS score improved from preoperative (74.93 ± 5.56) to (94.78 ± 3.98), FAOS score increased from preoperative (76.42 ± 3.37) to (96.16 ± 2.74), the VAS score decreased from (3.18 ± 0.54) to (1.07 ± 1.20) (p < 0.05), the length of spur decreased from (0.72 ± 1.81) cm to (0.23 ± 1.19) cm, and there were significant differences before and after operation (p < 0.05).

CONCLUSION

The four-step surgical regimen is an appropriate and effective surgical procedure to treat plantar fasciitis with bone spurs.

Are enlarged peroneal tubercle and accessory anterolateral talar facet associated with calcaneal spur?

BACKGROUND

As the anatomical variations of the foot, enlarged peroneal tubercle (EPT) and accessory anterolateral talar facet (AALTF) have attracted the attention of foot surgeons in recent years. However, EPT and AALTF have not been examined for a relationship with calcaneus spur (CS) as a common osteophyte.

METHODS

The subjects were 369 individuals who died in northeastern Thailand and were preserved as skeletal specimens. The authors examined for the presence of left and right EPT, AALTF, and calcaneus spur (CS). We divided the EPT (+) group with EPT and the EPT (-) group without it and also divided the AALTF (+) group with AALTF and the AALTF (-) group without it. The age at death and the presence of CS were compared statistically between the EPT (+) and EPT (-) groups and between the AATLF (+) and AALTF (-) groups.

RESULTS

Out of the total 369 cases, EPT was found in 117 cases (31.7%), AALTF was positive in 91 cases (24.7%), and CS was found in 194 cases (52.3%). In comparison between EPT (+) and EPT (-) groups, CS was significantly higher (p < 0.0001) in the EPT (+) group, but there was no significant difference in age at death. In comparison between AALTF (+) and AALTF (-) groups, there was no significant difference in age at death or CS.

CONCLUSION

This study showed a strong relationship between EPT and CS, and the prevalence of EPT and AALTF by age in Thailand was first reported. We believe it helps to know the pathogenesis and biomechanism of EPT and AALTF.

Comparison of Isolated Calcaneal Spur Excision and Plantar Fasciotomy in Addition to Spur Excision in Patients With Plantar Heel Pain Accompanied by Calcaneal Spur

INTRODUCTION

The aim of this study is to clinically compare isolated calcaneal spur excision and plantar fascia release in addition to spur excision in patients with plantar heel pain accompanied by a calcaneal spur.

METHOD

Patients who did not benefit from conservative treatment and underwent surgical excision of the calcaneal spur and/or plantar fasciotomy were retrospectively evaluated. The patients were divided into two groups according to the surgical procedure performed. The evaluation was done according to the pre- and postoperative foot function index (FFI) using pain and functional evaluation. Pain, disability, and activity restriction were evaluated with FFI. The radiological results and FFI scores of both groups were measured before and after surgery, and the difference between the groups was compared.

RESULTS

Of the 46 patients in our study group, 30 (65.2%) were female, and 16 (34.8%) were male. The average age was 41.2 years. There was a significant improvement in postoperative FFI scores in both groups. There was no significant difference in postoperative functional results when the groups were compared.

CONCLUSION

In patients whose plantar heel pain associated with calcaneal spur does not improve despite conservative treatments, both isolated spur excision and plantar fascia release in addition to spur excision may be effective treatment modalities that improve foot functions.

Effectiveness of mechanical treatment with customized insole and minimalist flexible footwear for women with calcaneal spur: randomized controlled trial

BACKROUND

Calcaneal spurs are described as bony outgrowths arising on medial calcaneal, where inappropriate footwear can promote disease progression.

OBJECTIVE

Investigate the effectiveness of mechanical treatment with customized insole and minimalist flexible footwear during gait training program in women with calcaneal spur.

METHODS

Design: A single-blinded, randomized and controlled trial.

SETTING

Biomechanics laboratory.

PARTICIPANTS

Forty-three women, 29 with calcaneal spur and 14 control.

INTERVENTION

Gait training program with use of the minimalist flexible footwear (MFG n = 15, age: 48.9 ± 9.4, height: 1.61 ± 0.1, BMI: 32.1 ± 7.0) and customized insole on footwear (COIG n = 14, age: 50.3 ± 5.8, height: 1.62 ± 0.1, BMI: 32.2 ± 4.3) and control (CG n = 14, age: 47.8 ± 8.6, height: 1.63 ± 0.1, BMI: 27.5 ± 4.5), followed of the evaluations: baseline (T0) and after three (T3) and six (T6) months. Duration of the intervention was of the six months consecutive for at least 42 h per week (six hours a day, seven days a week). Outcome primary were calcaneus pain (visual analogue scale), Foot Function Index (FFI), Foot Health Status Questionnaire (FHSQ-Br) and 6-min walk test (6MWT). Secondary was plantar pressure distribution by a pressure platform system during gait and static index foot posture (FPI).

STATISTICAL ANALYSIS

analysis of variance for repeated measure and between groups were used to detect treatment-time interactions (α = 5%). Effect size with D Cohen's also was used between T0 and after six (T6) months of intervention.

RESULTS

The MFG and COIG were effective at reducing pain after six months (MFG: 2.5-4.5 CI, p = 0.001; COIG: 1.5-3.5 CI, p = 0.011). The FFI and FHSQ-Br showed improvements with MFG and COIG after T6 (MFG: 13.7-15.4 CI, p = 0.010; COIG: 11.3-15.0 CI, p = 0.001). The 6MWT increased with MFG (589.3-622.7 CI) and COIG (401.3-644.7 CI) and foot pronation was decreased after T3 and T6 MFG (FPI Right: 4.2-5.4 CI; Left: 3.6-5.4 CI) COIG (FPI Right: 3.4-6.8 CI; Left: 3.3-5.7 CI). The contact area reduced on forefoot and rearfoot with MFG and GOIG and midfoot and rearfoot with MFG. Maximum force was reduced on foot with MFG after T3 and T6. The peak pressure was reduced on the forefoot with MFG and COIG and on midfoot and rearfoot with MFG.

CONCLUSIONS

The mechanical treatment with customized insole and minimalist flexible footwear during gait training program during six months in women with calcaneal spur reduced the calcaneus pain, increased function and health feet and reduced plantar load on the rearfoot, midfoot and forefoot. However, the footwear alone was more effective than when combined customized insole, given the greater efficacy on clinical and biomechanical aspects.

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

Objectives

The aim of this study was to investigate the 25-hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH), and calcitonin levels and lipid profiles in patients with calcaneal spurs.

Patients and methods

Between March 2018 and June 2019, a total of 50 patients (30 males, 20 females; mean age: 39.8±8.1 years; range, 24 to 54 years) admitted to our clinic with heel pain and diagnosed with heel spurs based on radiographic images were included. The control group consisted of 50 age- and sex-matched healthy volunteers (32 males, 18 females; mean age: 35.7±9.6 years; range, 20 to 56 years). Blood samples were collected from all participants. Total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride, phosphate, and calcium levels were measured using the colorimetric method. The PTH and 25(OH)D levels were measured using the chemiluminescent microparticle immunoassay. Calcitonin levels were detected using the chemiluminescent immunometric assay.

Results

In the patients with calcaneal spurs, 25(OH)D and HDL-C levels were significantly lower (p<0.001), while LDL-C, triglyceride, and PTH levels were significantly higher (p<0.05, p<0.002 and p<0.001, respectively). There was no significant difference in the calcium, phosphate, body mass index, and calcitonin levels between the groups.

Conclusion

Our study results suggest that calcaneal spur formation is associated not only with weight-related pressure, but also with lipid levels and hormonal alterations involved in calcium metabolism. Based on these findings, hormonal alterations and lipids should be considered in patients with calcaneal spurs.

Age, Body Mass Index, and Spur Size Associated with Patients’ Symptoms in Plantar Fasciitis

Background

Plantar fasciitis is a common cause of heel pain affecting 10% of the general population. This study aimed to investigate the specific symptoms in patients with plantar fasciitis using the Foot and Ankle Outcome Score (FAOS) questionnaire and their relationship with demographic and radiographic factors.

Methods

We retrospectively analyzed 73 consecutive patients (mean age, 53.8 ± 10.0 years; 20 men and 53 women) with plantar fasciitis who had visited our foot and ankle clinic and undergone weight-bearing foot X-ray examinations. Their demographic data, anteroposterior and lateral talo-first metatarsal angles, intermetatarsal and hallux valgus angles, and responses to the FAOS questionnaire were recorded.

Results

The quality-of-life subscale showed the lowest score of all FAOS subscales. Age was significantly correlated with quality of life (r = 0.297, p = 0.011), and body mass index was correlated with the function in sports and recreational activities (r = –0.251, p = 0.032). Age and body mass index were statistically significantly correlated with calcaneal spur size (r = 0.274, p = 0.027 and r = 0.324, p = 0.008, respectively). The calcaneal spur size was significantly correlated with pain (r = –0.348, p = 0.004), function in daily living (r = –0.410, p = 0.001), and function in sports and recreational activities (r = –0.439, p < 0.001).

Conclusions

Demographic factors were associated with specific symptoms in patients with plantar fasciitis. Calcaneal spur size was the only radiographic parameter correlated with symptoms. These findings help communicate with patients, set appropriate treatment goals, and evaluate treatment effectiveness.

A Design Study of Orthotic Shoe Based on Pain Pressure Measurement Using Algometer for Calcaneal Spur Patients

The pressure pain threshold (PPT) is a useful tool for evaluating mechanical sensitivity in individuals suffering from various musculoskeletal disorders. The aim of this study is to investigate PPT at the heel area in order to assist in the design of orthotic shoes for sufferers of heel pain due to a calcaneal spur. The size and location of the calcaneal spur was determined by x-ray images, with PPT data measured around the spur at five points by using algometer FDIX 25. The pain test experiment was conducted by pressing each point to obtain the pain minimum compressive pressure (PMCP) and its location. The information of shoe size, spur location and dimensions, and the PMCP location for each individual is used to obtain the exact point location for applying a softer material to the shoe in-sole, in order to reduce heel pain. The results are significant as it can be used by designers to design appropriate shoe in-soles for individuals suffering from heel pain.

The Clinical Efficacy of Two Endoscopic Surgical Approaches for Intractable Plantar Fasciitis

In this randomized retrospective study, 2 different endoscopic approaches were used to treat intractable plantar fasciitis with the aim to reduce complications and improve therapeutic effects. The lateral double incisions group included 23 feet in 22 patients, and the medial and lateral incisions group included 21 feet in 19 patients. Both groups were treated with endoscopy through the suprafascial approach. Patients were evaluated using the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale (AOFAS-AHS) and visual analog scale (VAS) preoperatively and 3, 6, 12, and 24 months postoperatively. At the final follow-up, the Roles-Maudsley (R-M) score was used to determine patient satisfaction. The AOFAS-AHS scores of the lateral double incisions group were 54.54 ± 7.02 preoperatively and 97.71 ± 3.67 postoperatively. Similarly, AOFAS-AHS scores in the medial and lateral incisions group were 55.52 ± 6.41 preoperatively and 96.64 ± 3.18 postoperatively. There was no significant difference in AOFAS-AHS scores between groups before and after surgery. The time to full weightbearing after surgery and the time to return to full athletic activities in the 2 groups showed no significant difference. The postoperative VAS scores were significantly lower than the preoperative values for both groups. However, no differences were noted in VAS scores or R-M scores postoperatively between the 2 groups. In the medial and lateral incisions group, 3 cases of injury of the first branch of the lateral plantar nerve occurred postoperatively. In conclusion, both endoscopic approaches are effective in the treatment of intractable plantar fasciitis. The lateral double incisions approach showed a lower incidence of nerve injury.

The Evaluation of Radiologic Angular Measurements in Patients with Foot Pain

BACKGROUND

The aim of this study was to investigate the relationship between foot deformities by comparing foot radiographs of patients with complaints of foot pain with those of healthy individuals.

METHODS

The study included 30 patients with pes cavus, 30 patients with pes planus, 30 patients with calcaneal spur, and 30 controls aged 30 to 60 years. All participants underwent measurement of right and left foot length; metatarsophalangeal width; and calcaneal pitch (CA), talohorizontal (TA), talometatarsal (TM), and lateral talocalcaneal (LTC) angles from lateral radiographs.

RESULTS

There were no statistically significant differences between all participants regarding sex, age, weight, and body mass index (P > .05). Among patients with clinically diagnosed pes cavus, the diagnostic rate of CA was 100% in both feet, and 83.3% in the right foot and 96.7% in the left foot according to the TM angle. The diagnostic rates of angular measurements in patients with pes planus were as follows: 20% in the right foot and 30% in the left foot depending on the CA angle, 100% in both feet depending on the TM angle, and 66.7% in the right foot and 46.7% in the left foot depending on the LTC angle. A very strong positive correlation was found between the CA and LTC angles in patients with calcaneal spur and pes planus (P < .001); also, statistically significant positive correlation was found between the CA and TA angles (P < .05). The angular measurements in patients with calcaneal spur were found to be consistent with pes planus with a high rate.

CONCLUSIONS

Angular changes caused by deterioration of foot biomechanics lead to various deformities. Pes planus ranks first among these. Therefore, we believe that radiographic angular measurements in patients presenting with foot pain in addition to clinical evaluation would be useful in considering associated deformities and planning treatments.

The Relationship between Calcaneal Spur Type and Plantar Fasciitis in Chinese Population

Plantar heel pain is a common disease with a high incidence in different races. It significantly reduced the quality of life of patients. However, the cause of PHP is still controversial and there were varieties of physiological factors associated with PHP. The most common pathological factor in the population was plantar fasciitis. Some existing research studies had found a correlation between calcaneal spurs and plantar fasciitis, and this study had found the correlation in Chinese population. It is invaluable not only to understand the relationship between different types of plantar calcaneal spurs and plantar fasciitis but also to identify the most appropriate treatment strategies. A total of 71 patients with calcaneal spurs were chosen from the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University. All 71 patients had completed X-rays and MRI scans; then, surgeons had removed their plantar calcaneal spurs. After surgery, all patients were followed up for 12 months; their prognosis was tested by the VAS and AOFAS scores. Type II (29, 40.8%) had the highest incidence in Chinese population, followed with type I (24, 33.8%) and type III (18, 25.4%). Preoperative VAS scores showed that type II (7.72 ± 1.10) was significantly higher than the other two types (P < 0.001). Postoperative VAS scores of type II were higher than those of type I and type III (P < 0.001). Postoperative AOFAS scores of type II were the lowest (P < 0.001). Researchers had proved that type II was more likely to cause PF.

Endoscopic plantar fascia release via a suprafascial approach is effective for intractable plantar fasciitis

PURPOSE

To evaluate the medium-term clinical results of endoscopic plantar fascia release (EPFR) using a suprafascial approach for recalcitrant plantar fasciitis.

METHODS

Twenty-four feet of twenty-three patients who underwent EPFR using a suprafascial approach were followed up for more than 2 years using the American Orthopedic Foot and Ankle Society (AOFAS) score. The AOFAS score at final follow-up was compared between patients who participated in athletic activity (group A) and those who were sedentary (group S) and between those with and those without calcaneal spur (group with CS and group without CS, respectively). The ability of patients to return to athletic activity, and if so, the time interval between surgery and return to athletic activity, were investigated in group A. Complications were recorded.

RESULTS

The median follow-up duration was 48 months. The mean AOFAS score in all patients increased significantly between before surgery and final follow-up (P < 0.001). The mean score in group A at final follow-up was significantly higher than that in group S (P < 0.05). However, there was no significant difference in the mean score at final follow-up between the groups with and without CS. In group A, all patients could return to athletic activity after a median 8 weeks. Injury to the first branch of the lateral plantar nerve occurred in three feet.

CONCLUSION

EPFR using a suprafascial approach was effective for recalcitrant plantar fasciitis. However, the prognosis of sedentary patients was inferior to that of patients engaged in athletic activity.

Bizarre calcaneal spur: A case report

INTRODUCTION

A calcaneal spur, also known as enthesophyte, is an abnormal bone outgrowth at the inferior part of the calcaneus, which is the most common site of bony spur occurrence. Although there is consensus that a calcaneal spur is a common cause of heel pain, approximately 20% of calcaneal spurs are asymptomatic and its pathology remains not fully understood.

PRESENTATION OF CASE

In this report, we present a rare case of a very large and bizarre calcaneal spur in a young adult man. The calcaneal spur was painful, which affected his foot function and was associated with plantar fasciitis. The spur length was measured in the radiograph and exhibited the longest calcaneal spur reported in the literature. The patient was treated conservatively, and he fully recovered his foot function.

DISCUSSION

This case was unique because although the patient presented with an extremely large unilateral calcaneal spur, he was young and did not have any chronic disease; hence, he was treated conservatively. The pain subsided and he regained full function of his foot. This case questions the association between calcaneal spur length and plantar fasciitis symptoms.

CONCLUSION

This case confirms that the length of calcaneal spurs, even extremely long ones, is not associated with the pathology of plantar fasciitis and that surgical treatment is not necessary.

Ultrasound Guidance Does Not Improve the Results of Shock Wave for Plantar Fasciitis or Calcific Achilles Tendinopathy: A Randomized Control Trial

OBJECTIVE

To establish whether the use of ultrasound to direct shock waves to the area of greater calcification in calcaneal enthesopathies was more effective than the common procedure of directing shock waves to the point where the patient has the most tenderness.

DESIGN

Two-armed nonblinded randomized control trial with allocation concealment.

SETTING

The Sports Clinic at Sydney University.

PATIENTS

Participants 18 years or older with symptomatic plantar fasciitis (PF) (with heel spur) or calcific Achilles tendinopathy (CAT). Seventy-four of 82 cases completed treatment protocol and 6-month follow-up.

INTERVENTIONS

Patients were randomized to receive either ultrasound-guided (UG) or patient-guided (PG) shock wave at weekly intervals over 3 to 5 weeks.

MAIN OUTCOME MEASURES

Reduced pain on visual analog scale (VAS) and improved functional score on Maryland Foot Score (MFS) (for PF) or Victorian Institute of Sport Assessment-Achilles (VISA-A) (for CAT). Follow-up was at 6 weeks and 3 and 6 months.

RESULTS

Comparative 6-month improvements in MFS for the 47 PF cases were PG +20/100 and UG +14/100 (P = 0.20). Comparative 6-month improvement in VISA-A score for the 27 CAT cases were PG +35/100 and UG +27/100 (P = 0.37). Comparative (combined PF and CAT) 6-month improvement in VAS pain scores for all 38 PG cases were +38/100 with +37/100 for all 36 UG shock wave cases.

CONCLUSIONS

Although both treatment groups had good clinical outcomes in this study, results for the 2 study groups were almost identical.

CLINICAL RELEVANCE

This study shows that there is no major advantage in the addition of ultrasound for guiding shock waves when treating calcaneal enthesopathies (PF and CAT).

Relationship and Classification of Plantar Heel Spurs in Patients With Plantar Fasciitis

BACKGROUND

This study classified plantar heel spurs and their relationship to plantar fasciitis.

METHODS

Patients included those with plantar fasciitis who were treated from 2012 through 2013. Plantar heel spur shape and size were assessed radiographically and correlated to function and pain before and after treatment. Function and pain were scored with the Foot and Ankle Ability Measures and a visual analog scale, respectively. This study included 109 patients with plantar fasciitis.

RESULTS

The plantar heel spur shape was classified as 0/absent in 26 patients, 1/horizontal in 66 patients, 2/vertical in 4 patients, and 3/hooked in 13 patients. The plantar heel spur size was less than 5 mm in 75 patients, 5-10 mm in 28 patients, and greater than 10 mm in 6 patients. Initially, patients with any shape or size to their spur had no difference in function and pain. With treatment, patients with horizontal and hooked spurs had the greatest improvement in function and pain (P < .05). With treatment, patients with larger spurs had the greatest improvement in function and pain (P < .05).

CONCLUSION

Plantar heel spurs can be classified by shape and size in patients with plantar fasciitis. Before treatment, neither the spur shape nor size significantly correlated with symptoms. After treatment, patients with larger horizontal or hooked spurs had the greatest improvement in function and pain. These findings may be important when educating patients about the role of heel spurs with plantar fasciitis and the effect of nonsurgical treatment with certain spurs.
