Abstract

Background: Functional outcome following ankle fracture fixation is linked to the restoration of joint congruity, anatomic alignment and stability. If surgical fixation fails to achieve these goals, revision surgery may be indicated. This retrospective study aims to report a consecutive series of fourteen patients with a minimum of one year follow up after revision ankle fixation and describe CT scan based modified Pettrone score used to assess quality of primary fixation.

Methods: Between April 2019 and August 2021, fourteen patients underwent revision ankle fracture fixation. Patients were identified by the multidisciplinary team through a review of intra-operative radiographs. Subsequently, a CT scan-based criteria which is modification of original Pettrone criteria based on plain radiographs was applied to further assess sub-optimal fixation. Demographic, clinical, radiological and patient-reported outcome measures data were collected and examined.

Results: Twelve patients exhibited protonation type injuries according to the Lauge-Hansen classification system. Syndesmotic joint was readdressed in eleven patients. The mean duration between the index surgery and the subsequent revision surgery was 46 days (inter-quartile range - 42 days). The mean Olerud-Molander Ankle Score was calculated as 58, with an IQR of 45. Similarly, the mean EQ-5D-3L VAS score was determined to be 69, with an IQR of 35. In our series, 60 % patients reported good to excellent results using OMAS. The quality-of-life scores of in these patients were also satisfactory.

Conclusion: We recommend early revision fixation should be considered when primary fixation is considered inadequate in early post-operative period. The modified Pettrone criterion can be used to assess sub-optimal fixation.
