ABSTRACT
[Objective] To investigate the diagnosis and treatment of congenital oblique talus in clinical practice.[Methods]Clinical situation of thirty-one patients displayed tarsoptosis and pas valgus,collapse in medial longitudinal instep,and with no talipes calcaneus,no contraction of tendon and no rigidity.All instep of the patients were restored to normal by chirismus.The X-ray of normotopia showed that axial ray of talus was declivent to wall and was angulated with No.1 metatarsal bones.The X-ray of lateral position showed that semiluxation of articulatio talonavicularis was noted,and axial ray of talus and No.1 metatarsal bones was not normal.The X-ray of lateral position of maximal plant flex and entropion showed that axial ray of talus and No.1 metatarsal bones was normal.Twenty-seven cases were cured by manipulation,4 cases were cured by operation,31 cases were cured by orthopaedic orthosis.[Results]All cases were curative during a follow-up of 12 to 24 months(mean,10 months).All outline forms of feet were good and no valgus calcaneus was found,the medial longitudinal instep were restored,the function of ankle and toes was normal,and the pedal force of enstrophe with ecstrophy was balance.The X-ray of normotopia showed that the angle of axial ray of talus to No.1 metatarsal bones was normal in 26 cases and ≤10? in 5 cases.Kite's angle was normal in 29 cases and ≤20? in 2 cases.The X-ray of lateral position showed that articulatio talonavicularis was good in 29 cases and ≤25? of talus to calcaneus in 6 cases.[Conclusion]Congenital oblique talus in infants can be cured by manipulation or operation.The prognosis is good.
