Objective To explore the correlation between the manifestations of patients with tarsal sinus injury on MRI im-ages and ankle ligament injury,so as to provide a more reliable basis for clinical diagnosis of tarsal sinus lesions.Methods 230 patients with tarsal sinus injury were retrospectively collected,of whom 124 were males,with an average age of 41.7±15.9 years,and 106 were females,with an average age of 48.9±14.5 years old.Ankle joint MRI plain scan images were obtained to observe the injury type of tarsal sinus and ankle ligament,and its rule and correlation was analyzed.Results 1)The main types of tarsal sinus injury were tarsal sinus ligament injury,synovium/ganglion cyst,effusion and tarsal sinus fibrosis.Injuries of tarsal sinus ligaments included cervical ligaments(CL),anterior and posterior tracts of intercalcaneal ligaments(ITCL),and subextensor retinae(IER),among which the anterior tracts of ITCL had the highest injury rate,followed by CL,IER,and poste-rior tracts of ITCL.2)① There was a positive correlation between CL and ITCL anterior bundle damage(r=0.318);② CL and IER damage were positively correlated(r=0.438);③ There was a positive correlation between anterior and posterior ITCL dam-age(r=0.353).3)The injuries associated with anterior talofibular ligament(ATFL)were 68.2％,followed by deltoid ligament(TRL)and calcaneal fibular ligament(CFL),with 33.3％and 30.3％,respectively.In ITCL anterior bundle injury,ATFL in-jury was 70.0％,followed by TRL that the injury was 35.7％,and then CFL injury was 21.4％.In ITCL posterior bundle injury,ATFL injury was the highest in 64.6％,followed by TRL injury in 29.2％and CFL injury in 16.7％.ATFL lesions were the most common in IER injuries(63.6％),followed by TRL injuries(30.9％)and CFL injuries(16.4％).Conclusion MRI manifesta-tions of tarsal sinus injury can be of various types.In the ligament of tarsal sinus,ITCL anterior bundle and CL are mostly in-jured,which are mostly multiple simultaneous injuries or a single injury.In the case of ATFL,CFL,TRL injury,attention should be paid to the sinus tarsi.
