PART ? MULTIMODAL IMAGING STUDY OF PLANT FASCIAObjective Ultrasound,CT and MRI were used to imaging the healthy adult feet,and the thickness of the plantar fascia was observed.The purpose was to compare the correlation of various imaging techniques in the plantar fascia,the advantages and disadvantages of different imaging techniques to the plantar fascia,and to determine the standard parameters of the plantar fascia.Methods From May 2015 to May 2017,50 healthy adult volunteers,25 women and 25 men were selected from the Affiliated Hospital of Inner Mongolia Medical University.The average age was 18-51 years old,the average was(31.6±3.5)years old,the height was 155-181 cm,the average was(172.3±7.6)cm,the weight 49-90 kg,and the average(78.3±3.6)kg.The thickness of plantar fascia on ultrasound image.recorded by CT and MRI scanning respectively.The original image data were imported into Materialise Mimics Innovation Suite 16.0 software in DICOM format.Thedata were analyzed digitally,measured and statistically analyzed.The imaging examination was carried out independently and blind by each professional operator.Ct and MRI scans were performed,the original image data were imported into Materialise Mimics Innovation Suite 16.0 software in DICOM format.The data were analyzed digitally,measured and statistically analyzed.The imaging examination was carried out independently and blind by each professional operator.Results The three methods of ultrasonography,CT and MRI were positively related to the results of the measurement of the beginning of the plantar fascia,the central tendon and the end of the plantar fascia.There was no significant difference in the thickness of the beginning of the plantar fascia,the central tendon and the stop point between the three groups(Male:F=0.040,P=1.000;F=0.112,P=1.000;F=0.586,P=0.840?Female:F=0.105,P=1.000;F=0.051,P=1.000;F=0.397,P=0.957.).There was no statistical difference between the measurements of the vertical section of the same examination position.Meaning(Male:lift,PFSP,F=0.034,P=1.000,PFCT,F=0.105,P=0.991,PFEP,F=0.226,P=0.951;right,PFSP,F=0.028,P=1.000,PFCT,F=0.047,P=0.999,PFEP,F=0.742,P=0.593?Female:lift,PFSP,F=0.101,P=0.992,PFCT,F=0.021,P=1.000,PFEP,F=0.399,P=0.849;right,PFSP,F=0.107,P=0.991,PFCT,F=0.076,P=0.996,PFEP,F=0.297,P=0.914.),there was no statistically significant difference between the left and right sides ofthe same sex(Male:LS,PFSP,F=0.029,P=1.000,PFCT,F=0.021,P=0.998,PFEP,F=0.657,P=0.657;TS,PFSP,F=0.052,P=0.998,PFCT,F=0.230,P=0.949,PFEP,F=0.428,P=0.829?Female,LS,PFSP,F=0.059,P=0.998,PFCT,F=0.076,P=0.996,PFEP,F=0.189,P=0.966;TS,PFSP,F=0.038,P=0.999,PFCT,F=0.032,P=0.999,PFEP,F=0.396,P=0.851.),but there was a significant difference between the male and female in the same side.The three tests showed that the average thickness of the plantar fascia in each site was greater than that of the female(US:left-LS,PFSP,F=1.217,P=0.0001,PFCT,F=1.738,P=0.006,PFEP,F=1.190,P=0.001;left-TS,PFSP,F=1.133,P=0.002,PFCT,F=1.482,P=0.004,PFEP,F=1.210,P=0.0001;right-LS,PFSP,F=1.000,P=0.0001,PFCT,F=2.103,P=0.0001,PFEP,F=1.361,P=0.0001;right-TS,PFSP,F=1.143,P=0.001,PFCT,F=1.397,P=0.009,PFEP,F=1.515,P=0.0001?CT:left-LS,PFSP,F=1.515,P=0.001,PFCT,F=1.210,P=0.001,PFEP,F=1.210,P=0.0001;left-TS,PFSP,F=1.138,P=0.002,PFCT,F=1.200,P=0.001,PFEP,F=1.000,P=0.0001;right-LS,PFSP,F=1.226,P=0.001,PFCT,F=1.089,P=0.001,PFEP,F=1.000,P=0.0001;right-TS,PFSP,F=1.133,P=0.002,PFCT,F=1.085,P=0.004,PFEP,F=1.397,P=0.0001?MRI:left-LS,PFSP,F=1.148,P=0.001,PFCT,F=1.590,P=0.006,PFEP,F=1.210,P=0.0001;left-TS,PFSP,F=1.066,P=0.002,PFCT,F=1.089,P=0.001,PFEP,F=1.190,P=0.001;right-LS,PFSP,F=1.143,P=0.001,PFCT,F=1.873,P=0.002,PFEP,F=1.000,P=0.001;right-TS,PFSP,F=1.000,P=0.004,PFCT,F=1.181,P=0.007,PFEP,F=1.174,P=0.0001?).The average thickness of normal metatarsal fascia of ultrasound in male was(2.86±0.31)mm,central(2.01±1.27)mm and stop point(1.32±0.13)mm.The average thickness of normal metatarsal fascia in female was(2.55±0.29)mm,(1.82±0.21)mm of central part and(1.16±0.13)mm at the end of the normal metatarsal fascia.Conclusion The three methods of ultrasonography,CT and MRI were positively related to the results of the measurement of the beginning of the plantar fascia,the central tendon and the end of the plantar fascia,and the ultrasonic image itself had a high credibility,which could provide a clinical basis for the measurement of the plantar fascia.Ultrasonic measurement with longitudinal section scan showed that the calcaneal tubercle was bone marker with good reproducibility.The thickness of the plantar fascia of the healthy men is greater than that of the female.PART ? DIAGNOSTIC VALUE OF ULRASOUND IN PLANTAR FASCIITISObjective Ultrasonic measurement of the thickness of the plantar fasciae of the healthy and plantar fasciitis of the healthy people and the plantar fasciitis.The ultrasonic changes of the patients with plantar fasciitis were observed by comparing the results of ultrasonic measurementsbetween the normal group and the plantar fasciitis group.Methods From May 2015 to May 2017,50 cases of plantar fasciitis and 42 cases of unilateral plantar fasciitis were diagnosed and confirmed in the Affiliated Hospital of Inner Mongolia Medical University.There were24 cases of women,18 males and 8 cases of bilateral plantar fasciitis,including 3 women and 5 men;the age was 27-65 years,average(47.4±11.4)years and height 155-178 cm,the average(168.2±6.5)cm,weight 55-80 kg,average(69.7±6.9)kg,healthy adult volunteers 50,25 women,25 men,age18-51 years,average(31.6±3.5)years,height 155-181 cm,average(172.3±7.6)cm,The average weight 49-90 kg was(78.3±3.6)kg.The plantar fascia thickness was observed and measured on the longitudinal part of the plantar fascia,the central tendon and the stop point,and the thickness of the plantar fascia was recorded.The data were statistically analyzed.Results Compared with the normal plantar plantar fasciae,the plantar fascioplantar fasciitis of the unilateral plantar fasciitis was more thicker than the central tendon,the difference was statistically significant(Female:F=21.302,P=1.8E-12;F=16.000,P=2.73E-10.? Male : F=6.797,P=5.06E-11;F=82.129,P=0.000).The plantar fascia thickness of the stop point was not statistically significant(Female:F=1.160,P=0.450;Male:F=1.562,P=0.070);the metatarsal fasciitis group was compared with the normal group,and the plantar fasciitis group was compared with thenormal group.The thickness of the plantar fascia was significantly thicker in the beginning and the central tendon(Female:F=13.444,P=7.31E-18;F=24.547,P=2.72E-13;Male:F=11.914,P=2.02E-16,F=16.00,,P=5.5E-12).There was no statistically significant difference in the thickness of the plantar fascia in the stop point(Female : F=1.361,,P=0.318;Male:F=1.563,P=0.200).The thickness of the plantar fasciae plantaris in the beginning of the plantar fasciitis,the thickness of the metatarsal fascia in the central tendon was thicker than the male,and the male of the stop point was thicker than the female(F=1.057,P=0.677;F=1.019,P=0.945;F=1.148,P=0.051)Conclusion The plantar fasciae were characterized by a marked thickening of the plantar fascia from the beginning of the plantar fascia to the central tendon,and the thickening of the stop point was not obvious.The starting part was the standard position of the measurement,the plantar fascia was clear,and the longitudinal section showed the bone sign of the calcaneus.PART ? DIAGNOSTIC VALUE OF X-RAY IN PLANTAR FASCIITISObjective The calcaneal-firstmetatarsal angle,plantar fascia thickness and calcaneal spur were measured in the lateral X-ray films of the feet.Correlation between calcaneal-firstmetatarsal angle,plantar fasciathickness,plantar calcaneal spur and plantar fasciitis were analyzed.To evaluate the diagnostic value of lateral X-ray films for plantar fasciitis.Methods From May 2015 to May 2017,50 cases of plantar fasciitis and 42 cases of unilateral plantar fasciitis were diagnosed and confirmed in the Affiliated Hospital of Inner Mongolia Medical University.There were24 cases of women,18 males and 8 cases of bilateral plantar fasciitis,including 3 women and 5 men;the age was 27-65 years,average(47.4±11.4)years and height 155-178 cm,the average(168.2±6.5)cm,weight 55-80 kg,average(69.7±6.9)kg,healthy adult volunteers 50,25 women,25 men,age18-51 years,average(31.6±3.5)years,height 155-181 cm,average(172.3±7.6)cm,The average weight49-90 kg was(78.3±3.6)kg.The lateral X-ray examination was performed.The images were stored in DICOM format,and the thickness of the plantar and metatarsal fascia and the calcaneal bone spines were measured.The data obtained were statistically analyzed.Results(1)The lateral X-ray films of the feet showed that the male and the plantar angle males were(130.78 + 2.63)°,the females were(131.32 + 2.19)°,and the plantar fasciitis patients were more than140°with the plantar angles.The normal feet of the unilateral plantar fasciitis were compared with the plantar fasciitis foot,the metatarsal plantar fasciae increased and the metatarsal fascia thickness increased,the difference was statistically significant(F=1.497,P=3.88E-15;F=16.784,P=8.88E-16).The heel plantar angle and the metatarsal fascia thickness were positively correlated;the normal group and the plantar fasciitis group were compared with the metatarsal fasciitis group,the metatarsal angle of the plantaris fasciitis group increased and the metatarsal fascia thickness was thicker.The difference was statistically significant(F=1.175,P=0.032;F=1.573,P=6.91E-9);there was no significant difference between the metatarsal angle and the thickness of metatarsal fascia between the female and the male(F=1.442,P=0.269),and the thickness of the metatarsal fascia measured by the foot X-ray side of the foot was positively correlated with the measurement results of ultrasound,CT and MRI.(2)In the normal group,there were 5 cases of foot bone spur,1 cases of Achilles tendon bone spur,2 cases of foot spur and Achilles tendon bone spur,32% of bone spur,4 cases of bone spur in male,2 cases of Achilles tendon,1 cases of Achilles tendon and sole spur,and 28% bone spur.In the plantar fasciitis group,there were 17 cases of bone spur in the foot,2 cases of Achilles tendon bone spur,3 cases of the Achilles tendon and the sole spur,the incidence of spur in 81.4%,the 12 cases of the male foot spur,the 3 cases of the Achilles tendon,2 cases of the Achilles tendon and the sole spur,and the incidence of bone spur in 73.9%.The average length of the calcaneal plantar spur is longer than that of the male,but the average length of the calcaneal calcaneal spur is longer.But there was no statistical difference(F=1.043,P=0.306;F=2.670,P=0.233).Conclusion The X-ray side of the foot showed that the normal population was male(130.78 + 2.63)°,female(131.32 + 2.19)°,the thickness of plantar fascia was less than 4mm,the pantar fasciitis was greater than 140 °,the thickness of plantar fascia was greater than 5mm,the greater the plantar fascia thickness of the calcaneal-firstmetatarsal angle was,the more obvious the plantar fascia was,the line was linear.Plantar calcaneal spur is easy to induce plantar fasciitis,but there is no correlation between the two correlations.
