Abstract
Background
PROMS and PREMS are a fundamental and essential part of the NHS. Chilectomy and fusion procedures for hallux rigidus produce varied outcomes due to their subjective nature. PROMS2.0, a semi-automated web-based system, which allows collection and analysis of outcome data, to compare what PROMS/PREMS for chilectomy/fusion for hallux rigidus are at UHSM including variance across osteoarthritis grades.
Methods
Data was collected from March-2013 to December-2014. Scores used to assess outcomes included EQ-5D-VAS, EQ-5D Health-Index, and MOxFQ, collected pre-operatively and post-operatively. Patient-Personal-Experience (PPE-15) was collected postoperatively. Data was compared.
Results
10 patients (4F, 6M) (9R, 1L) had a 1st MTPJ chilectomy. Average age- 47.3 (range 34–70). 16 patients (12F, 4M) (9RT, 7LT) had a 1st-MTPJ fusion. Average age-60.3yrs (range19–83)
Chilectomy pre-op average MOXFQ scores for pain, walking and social interaction: 33.5 (range 5–70), 27.6 (range 0–64) and 24.9 (range 0–75) respectively. Post operatively these improved to 25.0 (range 0–70), 24.3 (range 0–68) and 21.9 (range 0–50). EQ5D scores showed a regression; pre-op index average of 0.72 and post op 0.70. Pre-op VAS score average of 86.8 with post-op 80.4.
Fusion pre-op average MOXFQ scores for pain, walking and social interaction: 50.7 (range 25–75), 49.1 (range 4–75) and 48.4 (range 25–75) respectively. Post-operatively improved to 9.7 (range 0–57), 16.1 (range 0–57) and 20.1 (range 0–50). EQ5D scores showed improvement; with pre-op index average of 0.68 and post-op 0.83. Pre-op VAS score average of 72.5 and post-op 83.6. Higher grades of OA responded better to fusion and lower grades better to chilectomy. 17 patients (10 fusion/7 chilectomy) filled PPE-questionnaires. Results show overall satisfactory experience for both sets of patients.
Conclusion
Both procedures show improved outcomes. Fusions have greater improvements than chilectomy based on reported outcomes. Higher grades of OA do better with fusion.
