Medial displacement calcaneal osteotomy in treatment of stage II posterior tibial tendon deficiency

Background Medial displacement calcaneal osteotomy is indicated in individuals with stage 2 posterior tibial tendon deficiency (PTTD) with a supple hindfoot and the absence of clinical or radiographic arthritis. Patients and methods This prospective study evaluated the effects of medial displacement calcaneal osteotomy and flexor digitorum longus transfer to navicular bone on pedal realignment and function in 14 patients (15 feet) with a stage 2 PTTD. Results American College of Foot and Ankle Surgeons scoring scale module number 3 was measured before the reconstruction and at latest follow-up, and also patients’ satisfaction were reported, demonstrating a good realignment in short-term follow-up (15–18 months). The American College of Foot and Ankle Surgeons score improved postoperatively from average of 53.5 to 87.4 without progression of arthritis at adjacent joints. Conclusion This simple surgical procedure has an excellent effect on realignment and function of PTTD stage 2 without marked forefoot abduction.
