Clinical application of orthopedic on tarsal sinus graft filling in subtalar arthrodesis fusion tendon / 中国基层医药

ABSTRACT

Objective To assess the curative effect of the subtalar arthrodesis on the serious subtalar joint with the posterior tibial tendon dysfunction. Methods 31 patients with serious subtalar joint osteoarthrisis and stage Ⅱ posterior tibial tendon dysfunction were treated by the subtalar arthrodesis. The tibial tendon dysfunction involved 15 right and 16 left lower extremities,before the subtslar arthrodesis,the injured tendons were repaired,and then the bone grafting was performed in the tarsus sinus. All of the patients were assessed before and after operation according to the Hindfoot scores system. Results Among the patients,28 were followed up on an average of 23.6 months (range, 8～61 months ). The AOFAS scores ranged from (45.30±1.08 ) before operation to ( 79.60±2.14) after operation. The pain indexes ranged from ( 15.40±2.23) before operation to (38.50±2.61 ) after operation. The functional indices of the foot and ankle joint ranged from averaged (21.60±3.01 ) before operation to averaged (37.40±2.83) after operation. The angles between the longitudinal line of the talar and the calcaneal bone were (43.70±1.06)。 before operation and (29.40±0.98)。 after operation,and the deviation angles between the cal- eaneal line and the talus were (48.20±0.85)。 before operation and (39.40±1.02)。 after operation. There was a significant difference between before operation and after operation( P.< 0.01 ). Conclusion The subtalar arthrodesis combined with the bone grafting in the tarsus sinus and the repair of the injured tendons can effectively correct the deformity of the metapodium,relieve the pain,retain the adjacent joint motion ability,and this method can be recom- mended for the adult patient who suffers from serious subtalar osteoarthritis.
