Abstract:
Objective To explore the clinical and imaging manifestations of posterior tibial tendon dysfunction(PTTD).Methods A retrospective selection was conducted on 61 patients with clinically diagnosed PTTD.According to the classification criteria of Johnson and Strom,8 patients were classified as stage 1,17 as stage 2,20 as stage 3,and 16 as stage 4.The clinical manifestations and imaging features of patients were summarized at each stage.Results Among the 8 patients with stage 1 PTTD,no abnormalities were found on X-ray examination of the weight-bearing foot,while MRI revealed posterior tibial tendon(PTT)tendinitis in 4 cases(50.0％).For stage 2 patients(n=17),X-ray examination of the weight-bearing foot showed a decrease in the longitudinal arch of the foot in 15 patients(88.2％).MRI mainly revealed PTT degeneration in 12 cases(70.6％),PTT tears in 2 cases(11.8％),and other structural injuries in 5 cases(29.4％).For stages 3-4 patients(n=36),X-ray examination of the weight-bearing foot showed flatfoot in all cases.MRI mainly revealed PTT degeneration in 12 cases(33.3％),PTT tears in 24 cases(66.7％),spring ligament injuries in 33 cases(91.7％),and deltoid ligament injuries in 23 cases(63.9％).Conclusion Patients with stage 1 PTTD often have a normal foot longitudinal arch and may present with PTT tendinitis.Middle-aged females are more commonly affected by advanced PTTD,which is characterized by gradual decrease and collapse of the foot arch,accompanied by varying degrees of PTT degeneration and tears.The spring ligament injuries and deltoid ligament are frequently involved in structural injuries associated with PTTD.
