Abstract

Highlights: Large patient series from a single institution using multiple surgeons. Investigating non-union rates for 1 st MPJ fusion. A single compression and locking cross plate is associated with higher non-union rate compared to a separate interfragmentary compression screw and locking plate. Men at slightly great risk of non-union compared to women. Abstract: Background: The aim of this study was to determine if a single or separate construct with interfragmentary screw was associated with higher rates non-union following first metatarsophalangeal joint (MTPJ) arthrodesis. Methods: A retrospective analysis of patients undergoing first MTPJ arthrodesis between April 2010 and June 2017 was performed. Patients who received either a single (Stryker Anchorage 1 MTP Cross Plate) or separate (Stryker Anchorage 1 MTP locking plate with one Asnis partially threaded compression screw) construct locking plate and interfragmentary compression screw were reviewed. Descriptive statistics were generated for sample demographics and between-group differences were calculated. Multivariable regressions explored internal fixation type and association with non-union. Results: A total of 280 first MTPJ arthrodesis met the inclusion criteria and were reviewed. The incidence of non-union was 7.9% of procedures (22 joints). Following multivariable binary logistic regression, the single construct locking plate with interfragmentary compression screw was associated with an increased risk of non-union (OR 3.43, 95% CI 1.26–9.33), adjusting for age, gender and comorbidity. Conclusions: A single construct interfragmentary screw and locking plate (Stryker Anchorage 1 MTP Cross Plate) was associated with an increased incidence of non-union following first MTPJ arthrodesis.
