Abstract:
OBJECTIVE:To evaluate the clinical outcome of tibiotalocalcaneal fusion using cannulated screw and humeral proximal locking plate inverted fixation through a lateral transfibular approach.
METHODS:From June 2015 to December 2018, 15 patients underwent a tibiotalocalcaneal fusion operation using cannulated screw and inverted proximal humerus locking plate through a transfibular approach. There were 10 males and 5 females with the age ranging from 45 to 72 (58.9±6.1) years, and the course of disease ranged from 2 to 35 (11.9±7.9)years. Preoperative diagnosis included 8 cases of post traumatic arthritis, 2 cases of Charcot arthritis, 2 cases of Charcot-Marie -Tooth (CMT), 1 case of ankle tuberculosis, 1 case of talar necrosis, and 1 case of pigmented villonnodular synovitis. Among them, 8 patients were combined with simple varus deformity, 4 patients with simple valgus deformity, 2 patients with equinovarus deformity, 1 patient with equinovarus deformity, 2 patients with adduction and internal rotation of middle and forefoot. American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and the visual analogue scale (VAS) score were used to evaluate the clinical outcome at the last follow up.
RESULTS:One lost follow up and remaining fourteen patients were followed up. The follow up time ranged from 10 to 25(16.6±4.3) months. All the 15 patients had primary healing. Fusion time ranged from 15 to 24 (16.8 ± 2.4) weeks after operation. One patient with diabetes experienced delayed union and was successfully treated with secondary bone grafting combined with Platelet-Rich Plasma (PRP) injection. The AOFAS score increased from 38.7±3.3 to 84.5±2.6 (
CONCLUSION:Tibiotalocalcaneal fusion used cannulated screw and humeral proximal locking plate inverted fixation through a lateral transfibular approach has the advantages of relatively simple technique, high fusion rate, especially for patients with posterior foot deformity, which has satisfactory short term effects.
