Abstract
- Purpose: This study compared the clinical effectiveness and wound complications of a three-dimensional model-assisted spatial weaving screw fixation (3D-SWSF) versus open reduction and internal fixation (ORIF) via an L-shaped extensile lateral approach for calcaneal fractures. Methods: This single-centre retrospective cohort study was conducted with two cohort groups in which patients with Sanders II and III calcaneal fractures underwent 3D-SWSF or conventional ORIF. The clinical outcome measures included operation duration, time to operation, wound complications, blood loss volume, hospital stays, American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score, and visual analog scale (VAS) score. The pre-operative, post-operative, and one-year follow-up Gissane's angle (GA), Böhler's angle (BA), height, and width and length of the calcaneal fractures were also compared between the two groups. Results: From Oct 2015 to Oct 2019, 31 patients received 3D-SWSF and 41 received conventional ORIF. A total of 11 (26.8%) patients in ORIF group had wound complications, compared with only two (6.5%) in 3D-SWSF group (p = 0.032). Operative time, blood loss, and hospital stay in 3D-SWSF group were lesser than those in ORIF group. The patients treated with 3D-SWSF had better AOFAS and VAS scores than those treated with ORIF at the last follow-up. The post-operative and one-year follow-up radiographic indexes as well as the GA, BA, length, width, and height of the calcaneal fractures were relatively comparable between the two groups. Conclusion: Our study revealed that 3D-SWSF could effectively decrease the risk of wound complications, shorten operation time, reduce length of hospitalization, and improve post-operative rehabilitation.
