Abstract

Objective: To evaluate the effectiveness of the transfer function of the FLD tunnel to the tarsal scaphoid vs tenodesis at the distal stump of the posterior tibial tendon. Methods: We performed a retrospective comparative study of patients with this disease in the Foot and Ankle Unit of HCC between 2005 and 2012, in 27 patients FDL tunnel was performed in the tarsal navicular and in 49 patients FDL tenodesis was performed to the distal posterior tibial tendon stump; in all patients a bone procedure was performed to correct acquired deformity of the hindfoot. Goniometrical measurement was performed of forefoot inversion and plantar flexion at 12 months postop and compared with the healthy foot. Pain or loss of function in the transfer zone was evaluated. Statistical analysis was performed using t Student test. Results: Six patients had bilateral PTTD and were excluded from this study. Patients with tarsal scaphoid FDL tunnel showed a mean of 62% forefoot inversion and 86% of plantar flexion, patients with FDL tenodesis, showed an average of 86% forefoot inversion and 89% of plantar flexion. One tendon tunnel patient lost tendon function and 2 tenodesis patient lost tendon function. 2 patients with FDL tenodesis had pain in the transfer area. Conclusion: From our study we can conclude that FDL tenodesis to the distal posterior tibial tendon stump produces a better forefoot inversion than the FDL tarsal navicular tunnel.
