Lateral open wedge calcaneus osteotomy with bony allograft augmentation in adult acquired flatfoot deformity. Clinical and radiological results

Abstract

The aim of this study is to evaluate the results of patients underwent lateral open wedge calcaneus osteotomy with bony allograft augmentation combined with tibialis posterior and tibialis anterior tenodesis. Twenty-two patients underwent adult-acquired flatfoot deformity were retrospectively evaluated with a minimum 2-year follow-up. Radiographic preoperative and final comparison of tibio-calcaneal angle, talo–first metatarsal and calcaneal pitch angles have been performed. The Visual Analog Scale, American Orthopedic Foot and Ankle Score, the Foot and Ankle Disability Index and the Foot and Ankle Ability Measure were used for subjective and functional assessment. The instrumental range of motion has been also assessed at latest follow-up evaluation and compared with preoperative value. There was a significant improvement of final mean values of clinical scores (p < 0.001). Nineteen out of 22 (86.4%) patients resulted very satisfied or satisfied for the clinical result. There was a significant improvement of the radiographic parameters (p < 0.001). There were no differences between preoperative and final values of range of motion. One failure occurred 7 years after surgery. Adult-acquired flatfoot deformity correction demonstrated good mid-term results and low recurrence and complications rate. Level of evidence Level 4, retrospective case series.

Outcomes and Complications Associated with Lateral Column Lengthening Using Porous Titanium Wedges for Flexible Flatfoot Deformity Correction: A Systematic Review

“…These outcome scores are similar to previously published literature on allograft wedges utilized for LCL. Colo,' et al evaluated outcome scores following LCL utilizing a bony allograft wedge [25]. They found VAS scores improved from 7.7 ± 0.7 (7)(8)(9) preoperatively to 1.8 ± 1.6 (0-7) at final follow-up, while FAAM scores improved from 36.6 ± 6.2 (30-52) preoperatively to 71.8 ± 11.2 (25-84) at final follow-up.…”
