Evans Osteotomy Without Bone Graft in Stage IIB Adult Flatfoot Deformity
Abstract
Objective: To evaluate the radiological and functional outcomes one year after surgery in a consecutive series of patients diagnosed with stage IIB adult-acquired flatfoot deformity who underwent Evans osteotomy without the use of bone graft. Materials and Methods: Two groups of patients were retrospectively evaluated: group 1 (spacer plate, n=12) and group 2 (PEEK cage, n=14). The mean age was 47 years (SD 18) in group 1 and 54 years (SD 12) in group 2. Results: 26 patients (28 feet) were evaluated; 14 (84%) of the patients were women. Radiographic measurements—calcaneal pitch angle, (lateral) talocalcaneal angle, (AP) talocalcaneal angle, talonavicular coverage angle, medial column height, lateral column length—yielded statistically significant differencesbetween preoperative measurements and those taken one year after surgery. The mean score on the AOFAS scale one year after surgery was 96 (SD 4.70) in group 1 and 95 (SD 4.98) in group 2. Regarding the visual analog scale, it was 1.2 (SD 0.42) in group 1 and 1.16 (SD 0.46) in group 2. Conclusions: According to the results obtained, we conclude that Evans osteotomy without the use of bone graft manages to preserve the corrections obtained in the medium term, using either spacer plates or PEEK cages.Downloads
