description | Category: Bunion Introduction/Purpose: Little is known about the long-term results of percutaneous hallux valgus correction, particularly the recurrence rate and factors leading to recurrence. Methods: We retrospectively reviewed a single surgeon consecutive series of percutaneous chevron and akin osteotomies (PECA) performed between 2012-14 on 127 feet in 86 patients. Mean age was 52+-13 years at surgery and mean follow up (FU) was 69+-7 months. Patient reported outcome measures (PROMs) were completed by 65 patients (MOXFQ, VAS pain (0-100)) and Likert satisfaction scale by 86 patients. Pre-operative, 6 month and final follow up weight bearing radiographs were available for 68 feet. Radiological parameters measured were the hallux valgus angle (HVA) and 1-2 intermetatarsal angle (IMA). The data was normally distributed and presented as mean+-SD. Paired t-test was used to compare pre- and post-operative angles. Ordinal logistic regression was used to test for significant dependent variables on PROMs. Results: Mean MOXFQ was 10+-16 and mean VAS pain was 6+-13 out of 100 at a mean FU of 69+-7 months. 99% (85/86) patients were highly satisfied or satisfied. Mean HVA improved from 28.3+-8.1º to 8.4+-5.6º at final FU (p<0.001). No clinically relevant difference in HVA was seen between 6 months and final FU. Mean IMA improved from 12.7+-2.9º to 6.2+-2.7º at final FU (p<0.001). 2.9% (2/68) had an HVA >20º at final FU, these both started with a pre-operative HVA >40°. Pre-operative HVA >40º was significantly more likely to have an HVA >20º at final FU than those with pre-operative HVA <40º (22% vs 0%, p<0.001). There were 5 re-operations for removal of screws. 1 foot had hallux varus, but was still satisfied. Conclusion: The 5 year results for PECA hallux valgus correction show high levels of patient satisfaction, function and pain relief, with low complication and re-operation rates. Radiological correction is maintained at long term FU. |
