Clinical Research Of Bone Cement Injection For Calcaneodynia

Objective:Bone cement injection for calcaneodynia is a self-researched method for calcaneodynia in our hospital.The purpose of this study is to observe the clinical efficacy of this treatment method and to study and discuss the effects of different types of calcaneodynia and different amounts of bone cement injection on the clinical efficacy.To better provide theoretical basis and reference for clinical treatment of heel pain.Method:Bone cement injection for calcaneodynia has entered the clinical trial stage,and 12 patients with calcaneodynia have been treated with this method.A retrospective analysis was made on 12 patients with heel pain from February 2018 to February 2019,including 8 patients with right foot and 4 patients with left foot.There were 7 males and 5 females,aged 40-70 years with an average of 56 years.The history of heel pain ranged from 9 to 36 months with an average of 15 months.All the patients came to our hospital with poor curative effect after treatment by various methods,and were treated by bone cement injection.Collected pain score(VAS score)and AOFAS ankle-hindfoot score before and after treatment,and the amount of bone cement injected,record the amount of bone cement injected,the presence or absence of bone cement leakage,allergy,infection at the puncture site,etc.All patients were followed up for at least 1 year after treatment.According to the presence or absence of fixed tenderness points on heel,they were divided into fixed tenderness points group(group A)with 7 cases and fixed tenderness points group(group B)with 5 cases.According to the different injected amount of bone cement during the operation,it is divided into two groups:low-dose group(1.0ml≤V≤1.5ml)and high-dose group(1.5ml<V≤2.0),with 6 cases in each group.Statistical methods were used to compare the Visual Analogue Scale(VAS)score and AOFAS ankle-hindfoot score at each time point before treatment(T0),2 weeks after treatment(T1),and lyear after treatment(T2).Correlation analysis was conducted between the cement injection amount and the pain relief degree after treatment to judge the effects of different types of heel pain,different cement injection amount on the treatment effect,and whether there was correlation between the cement injection amount and pain relief.Results:1.Pain and function of all patients were effectively relieved after bone cement injection.VAS score of each group after treatment was lower than that before treatment,and AOFAS ankle-hind foot score was higher than that before treatment,with statistical difference(P<0.05);2.The VAS score and AOFAS ankle-hindfoot score of the two types of calcaneodynia patients at different time points before and after treatment with bone cement injection were compared.there was no significant difference between the two groups(P>0.05);3.There was no significant difference in VAS score and AOFAS ankle-hindfoot score between the groups before treatment with different bone cement injections(P>0.05).Compared with the low-dose group at different time points after treatment,the high-dose group with VAS score is lower than the low-dose group,and the high-dose group with AOFAS ankle-hindfoot score is higher than the low-dose group,all of which have statistical differences(P<0.05),and the different bone cement injection amount and pain relief degree(the difference of VAS score before and after treatment)are correlated(R=0.985;P=0.000<0.001).Conclusion:Different types of calcaneodynia patients have achieved good results after bone cement injection treatment.The bone cement injection amount in the range of 0.5-2.0ml can effectively relieve pain and improve function,and the treatment effect increases with the increase of dosage in this range.The treatment method is a newly developed minimally invasive treatment method,and has the characteristics of simplicity,safety,small trauma,quick recovery,short treatment time,obvious effect,economy and practicability,no hospitalization,and has wide application prospect.
